Abstract
We characterize the equation of state (EoS) of the SU(N>2) Fermi-Hubbard Model (FHM) in a two-dimensional single-layer square optical lattice. We probe the density and the site occupation probabilities as functions of interaction strength and temperature for N=3, 4, and 6. Our measurements are used as a benchmark for state-of-the-art numerical methods including determinantal quantum Monte Carlo and numerical linked cluster expansion. By probing the density fluctuations, we compare temperatures determined in a model-independent way by fitting measurements to numerically calculated EoS results, making this a particularly interesting new step in the exploration and characterization of the SU(N) FHM.

Abstract
Pancreatic cancer has the worst prognosis among all cancers, underscoring the need for improved management strategies. Dysregulated mitochondrial function is a common feature in several malignancies, including pancreatic cancer. Although mitochondria have their own genome, most mitochondrial proteins are nuclear-encoded and imported by a multi-subunit translocase of the outer mitochondrial membrane (TOMM). TOMM22 is the central receptor of the TOMM complex and plays a role in complex assembly. Pathobiologic roles of TOMM subunits remain largely unexplored. Here we report that TOMM22 protein/mRNA is overexpressed in pancreatic cancer and inversely correlated with disease outcomes. TOMM22 silencing decreased, while its forced overexpression promoted the growth and malignant potential of the pancreatic cancer cells. Increased import of several mitochondrial proteins, including those associated with mitochondrial respiration, was observed upon TOMM22 overexpression which was associated with increased RCI activity, NAD+/NADH ratio, oxygen consumption rate, membrane potential, and ATP production. Inhibition of RCI activity decreased ATP levels and suppressed pancreatic cancer cell growth and malignant behavior confirming that increased TOMM22 expression mediated the phenotypic changes via its modulation of mitochondrial protein import and functions. Altogether, these results suggest that TOMM22 overexpression plays a significant role in pancreatic cancer pathobiology by altering mitochondrial protein import and functions. IMPLICATIONS TOMM22 bears potential for early diagnostic/prognostic biomarker development and therapeutic targeting for better management of patients with pancreatic cancer.

Abstract
MYB acts as a potentiator of aggressiveness and castration resistance in prostate cancer (PCa) through aberrant activation of androgen receptor (AR) signaling. Since Black men experience higher PCa incidence and mortality than White men, we examined if MYB was differentially expressed in prostate tumors from patients of these racial backgrounds. The data reveal that aberrant MYB expression starts early in precancerous high-grade prostate intraepithelial neoplastic lesions and increases progressively in malignant cells. PCa tissues from Black patients exhibit higher MYB expression than White patients in overall and grade-wise comparisons. MYB also exhibits a positive correlation with AR expression and both display higher expression in advanced tumor stages. Notably, we find that MYB is a better predictor of biochemical recurrence than AR, pre-treatment PSA, or Gleason's grades. These findings establish MYB as a promising molecular target in PCa that could be used for improved risk prediction and therapeutic planning.

Abstract
Microalgae, as photosynthetic organisms, have the potential to produce biomolecules for use in food, feed, cosmetics, nutraceuticals, fuel, and other applications. Faster growth rates and higher protein and lipid content make microalgae a popular chassis for many industrial applications. However, challenges such as low productivity and high production costs have limited their commercialization. To overcome these challenges, bioengineering approaches such as genetic engineering, metabolic engineering, and synthetic biology have been employed to improve the productivity and quality of microalgae-based products. Genetic engineering employing genome editing tools like CRISPR/Cas allows precise and targeted genetic modifications. CRISPR/Cas systems are presently used to modify the genetic makeup of microalgae for enhanced production of specific biomolecules. However, these tools are yet to be explored explicitly in microalgae owing to some limitations. Despite the progress made in CRISPR-based bioengineering approaches, there is still a need for further research to optimize the production of microalgae-based products. This includes improving the efficiency of genome editing tools, understanding the regulatory mechanisms of microalgal metabolism, and optimizing growth conditions and cultivation strategies. Additionally, addressing the ethical, social, and environmental concerns associated with genetic modification of microalgae is crucial for the responsible development and commercialization of microalgae-based products. This review summarizes the advancements of CRISPR-based bioengineering for production of industrially important biomolecules and provides key considerations to use CRISPR/Cas systems in microalgae. The review will help researchers to understand the progress and to initiate genome editing experiments in microalgae.

Abstract
The true coincidence summing correction factor for a Broad Energy Germanium detector has been calculated at far and close geometry set-up using radioactive γ-ray sources. The correction factors were calculated using both experimental and analytical methods. Geant4 simulation was done to calculate the full-energy peak and total efficiencies of the detector. Standard, as well as fabricated mono-energetic γ-ray sources, were used for the γ-ray efficiency measurements. The simulated efficiencies of mono-energetic γ-ray sources were matched to the experimental γ-ray efficiencies by optimizing the detector parameters. The same parameters were used to obtain the full-energy peak and total efficiencies for γ-rays of current interest. Analytical and experimental correction factors were found to agree well with each other. The coincidence summing effect is found to be significant for source-to-detector distances less than 5 cm.

Abstract
Early detection and recurrence prediction are challenging in triple-negative breast cancer (TNBC) patients. We aimed to develop mitochondrial DNA (mtDNA)-based liquid biomarkers to improve TNBC management. Mitochondrial genome (MG) enrichment and next-generation sequencing mapped the entire MG in 73 samples (64 tissues and 9 extracellular vesicles [EV] samples) from 32 metastatic TNBCs. We measured mtDNA and cardiolipin (CL) contents, NDUFB8, and SDHB protein expression in tumors and in corresponding circulating EVs. We identified 168 nonsynonymous mtDNA mutations, with 73% (123/186) coding and 27% (45/168) noncoding in nature. Twenty percent of mutations were nucleotide transversions. Respiratory complex I (RCI) was the key target, which harbored 44% (74/168) of the overall mtDNA mutations. A panel of 11 hotspot mtDNA mutations was identified among 19%-38% TNBCs, which were detectable in the serum-derived EVs with 82% specificity. Overall, 38% of the metastatic tumor-signature mtDNA mutations were traceable in the EVs. An appreciable number of mtDNA mutations were homoplasmic (18%, 31/168), novel (14%, 23/168), and potentially pathogenic (9%, 15/168). The overall and RCI-specific mtDNA mutational load was higher in women with African compared to European ancestry accompanied by an exclusive abundance of respiratory complex (RC) protein NDUFB8 (RCI) and SDHB (RCII) therein. Increased mtDNA (p < 0.0001) content was recorded in both tumors and EVs along with an abundance of CL (p = 0.0001) content in the EVs. Aggressive tumor-signature mtDNA mutation detection and measurement of mtDNA and CL contents in the EVs bear the potential to formulate noninvasive early detection and recurrence prediction strategies.

Abstract
Early detection, accurate monitoring, and therapeutics are major problems in non-small-cell lung cancer (NSCLC) patients. We identified genomic copy number variation of a unique panel of 40 mitochondria-targeted genes in NSCLCs (GEOGSE #29365). Validation of mRNA expression of these molecules revealed an altered panel of 34 genes in lung adenocarcinomas (LUAD) and 36 genes in lung squamous cell carcinomas (LUSC). In the LUAD subtype (n = 533), we identified 29 upregulated and 5 downregulated genes, while in the LUSC subtype (n = 502), a panel of 30 upregulated and 6 downregulated genes were discovered. The majority of these genes are associated with mitochondrial protein transport, ferroptosis, calcium signaling, metabolism, OXPHOS function, TCA cycle, apoptosis, and MARylation. Altered mRNA expression of SLC25A4, ACSF2, MACROD1, and GCAT was associated with poor survival of the NSCLC patients. Progressive loss of SLC25A4 protein expression was confirmed in NSCLC tissues (n = 59), predicting poor survival of the patients. Forced overexpression of SLC25A4 in two LUAD cell lines inhibited their growth, viability, and migration. A significant association of the altered mitochondrial pathway genes with LC subtype-specific classical molecular signatures was observed, implicating the existence of nuclear-mitochondrial cross-talks. Key alteration signatures shared between LUAD and LUSC subtypes including SLC25A4, ACSF2, MACROD1, MDH2, LONP1, MTHFD2, and CA5A could be helpful in developing new biomarkers and therapeutics.

Abstract
Abstract
Smoking is among the most significant preventable risk factors associated with cancer and other benign diseases. Cancer development is a multi-step process in which transforming cells gradually gain malignant properties through a series of oncogenic genetic alterations. Successful cancer progression also depends on the remodeling of the surrounding stroma, which feeds the cancer cells in a host-parasite interaction. Tumor angiogenesis, the process of blood vessel formation, is an essential feature of solid tumors that ensures that they have the needed supply of food and oxygen to sustain their proliferative growth. We previously demonstrated that nicotine, an addictive component of tobacco smoke, promoted tumor angiogenesis by impacting the growth of endothelial cells. In the present work, we examined the differences in tumor vasculature between smoker and non-smoker patients to find clinical support for our laboratory findings. After searching the available tumor cases in the repository for the patient’s smoking history, I selected 27 smokers (12 lung and 15 prostate adenocarcinomas) and 19 non-smokers (4 lung and 15 prostate adenocarcinomas) cases. The tissue blocks were sectioned and subjected to hematoxylin and eosin staining and immunohistochemistry using an antibody against CD31, a biomarker for endothelial cells. Following digital scanning, all slides were reviewed to identify tumor areas and CD31+ tubular structures (blood vessels). We observed that lung and prostate tumor tissues from smoker patients had a significantly higher number of blood vessels than those from non-smoker patients. Thus, increased tumor vascularization appears to be a common feature of smoking cancer patients providing clinical support for a novel mechanism by which smoking may contribute to tumor pathobiology.

Abstract
In our country majority of the coronary artery bypass surgery (CABG) are done off-pump and was reported having excellent clinical outcome along with cost efficiency by various investigators. Heparin is commonly used as most effective anticoagulant, and protamine sulfate is now generally used to reverse the anticoagulant action of heparin. While under dosing of protamine may result in incomplete heparin reversal and prolonged anticoagulation, protamine overdosing is associated with impaired clot formation exerted by the intrinsic anti-coagulation properties of protamine itself, moreover protamine administration is associated with mild to severe cardiovascular and pulmonary complications. Apart from traditional full neutralization of heparin now-a-days, half dose protamine was also introduced showing good outcome regarding lower activated clotting time (ACT), overall, less surgical bleeding with less transfusion. This comparative study was designed to detect differences between traditional and decreased protamine dosing in Off-Pump Coronary Artery Bypass (OPCAB) surgery. Four hundred (400) patients who underwent Off-Pump Coronary Artery Bypass Surgery (OPCAB) surgery at our institution over a period of 12 months were analyzed and were divided into two groups. Group A- received 0.5mg of protamine per 100 unit of heparin; Group B-received 1.0mg of protamine per 100 unit of heparin. ACT, blood loss, hemoglobin and platelet count units of blood and blood product transfusion requirements, clinical outcome and hospital stay were assessed in each patient. This study showed that 0.5mg of protamine per 100 unit of heparin was always able to reverse the anticoagulant effect of heparin with no significant difference in hemodynamic parameters, amount of blood loss and requirements of blood transfusion in between the groups. A standard protamine dosing formula (protamine-heparin at ratio of 1:1) adequate for on-pump cardiac surgical procedures significantly overestimates protamine requirements for OPCAB. Patients treated with decreased protamine do not appear to have adverse outcomes in terms of post-operative bleeding.

Abstract
Background and Objective The global impact of cancer and cancer-related deaths has been a huge challenge and continues to be a setback in the health sector and beyond even in recent times. Cancer is the second leading cause of death globally with lung cancer (LC) being the second most prevalent malignancy and the leading cause of mortality amongst cancers in men and women worldwide. LC still constitutes a major burden despite recent advances in diagnostic and treatment tools. In this article, we review the trends in LC with an emphasis on non-small cell LC. We aimed to identify nuclear and mitochondrial genetic alterations, microbiome dysbiosis, and their significance in non-small cell LC tumorigenesis as well as its relevance in the future management of LCs. Methods We identified studies for this review by searching the PubMed, Cochrane, Education Resources Information Center (ERIC), and Surveillance, Epidemiology, and End Results (SEER) databases for English-Language articles published from January 1, 2000 through to July 30, 2022, using keywords: lung cancer, non-small cell lung cancer, early detection, treatment, mitochondria, microbiome and epigenetics. Key Content and Findings This review will highlight the genomic environment, mitochondrial and nuclear alterations that play a role in the etiopathogenesis of LC and its application in the progression as well as management of the disease. We also elaborate on current molecular tumor biomarkers and their therapeutic targets. Conclusions LC remains the leading cause of cancer-related deaths globally with poor prognosis despite available treatment options and even recent advances in both diagnostic tools and management guidelines. Human nuclear and mitochondrial alterations clearly play a role in tumorigenesis and progressive genomic evolution is crucial in the early carcinogenesis of LC which is strongly influenced by host immune surveillance. It is imperative that more research and clinical trials be undertaken to appreciate an in-depth understanding of LC from the molecular level to facilitate the discovery of more targeted therapy and overall better management of LC.

Abstract
Microalgae cultivation utilizes the energy of sunlight to reduce carbon dioxide (CO2) for producing renewable energy feedstock. The commercial success of the biological fixation of carbon in a consistent manner depends upon the availability of a robust microalgae strain. In the present work, we report the identification of a novel marine Nannochloris sp. through multiparametric photosynthetic evaluation. Detailed photobiological analysis of this strain has revealed a smaller functional antenna, faster relaxation kinetics of non-photochemical quenching, and a high photosynthetic rate with increasing light and temperatures. Furthermore, laboratory scale growth assessment demonstrated a broad range halotolerance of 10-70 parts per thousand (PPT) and high-temperature tolerance up to 45 °C. Such traits led to the translation of biomass productivity potential from the laboratory scale (0.2-3.0 L) to the outdoor 50,000 L raceway pond scale (500-m2) without any pond crashes. The current investigation revealed outdoor single-day peak areal biomass productivity of 43 g m-2 d-1 in summer with an annual (March 2019-February 2020) average productivity of 20 g m-2 d-1 in seawater. From a sustainability perspective, this is the first report of successful round-the-year (> 347 days) multi-season (summer, monsoon, and winter) outdoor cultivation of Nannochloris sp. in broad seawater salinity (1-57 PPT), wide temperature ranges (15-40 °C), and in fluctuating light conditions. Concurrently, outdoor cultivation of this strain demonstrated conducive fatty acid distribution, including increased unsaturated fatty acids in winter. This inherent characteristic might play a role in protecting photosynthesis machinery at low temperatures and in high light stress. Altogether, our marine Nannochloris sp. showed tremendous potential for commercial scale cultivation to produce biofuels, food ingredients, and a sustainable source for vegetarian protein.

Abstract
There is a complete lack of highly sensitive and specific biomarkers for early pancreatic ductal adenocarcinoma (PDAC) diagnosis, limiting multi-modal therapeutic options. Mitochondrial DNA (mtDNA) is an excellent resource for biomarker discovery because of its high copy number and increased mutational frequency in cancer cells. We examined if mtDNA mutations can be detected in circulating extracellular vesicles (EVs) of PDAC patients and used for discerning between cancer and non-cancer subjects. A greater yield of circulating EVs (~ 1.4 fold; p = 0.002) was obtained in PDAC patients (n = 20) than non-cancer (NC) individuals (n = 10). PDAC-EVs contained a higher quantity of total DNA (~ 5.5 folds; p = 0.0001) than NC-EVs and had greater enrichment of mtDNA (~ 14.02-fold; p = 0.0001). PDAC-EVs also had higher levels of cardiolipin (a mitochondrial inner-membrane phospholipid), suggestive of their mitochondrial origin. All mtDNA mutations in PDAC-EVs were unique and frequency was remarkably higher. Most mtDNA mutations (41.5%) in PDAC-EVs were in the respiratory complex-I (RCI) (ND1-ND6), followed by the RCIII gene (CYTB; 11.2%). Among the non-coding genes, D-Loop and RNR2 exhibited the most mutations (15.2% each). Altogether, our study establishes, for the first time, that mtDNA mutations can be detected in circulating EVs and potentially serve as a tool for reliable PDAC diagnosis.

Abstract
BACKGROUNDS Microbiome dysbiosis is an important contributing factor in tumor development and thus may be a risk predictor for human malignancies. In the United States, women with Hispanic/Latina (HIS) and African American (AA) background have a higher incidence of cervical cancer and poorer outcomes than Caucasian American (CA) women. METHODS Here, we assessed the distribution pattern of microbiota in cervical intraepithelial neoplasia (CIN) lesions obtained from HIS (n = 12), AA (n = 12), and CA (n = 12) women, who were screened for CC risk assessment. We employed a 16S rRNA gene sequencing approach adapted from the NIH-Human Microbiome Project to identify the microbial niche in all CIN lesions (n = 36). RESULTS We detected an appreciably decreased abundance of beneficial Lactobacillus in the CIN lesions of the AA and HIS women compared to the CA women. Differential abundance of potentially pathogenic Prevotella, Delftia, Gardnerella, and Fastidiosipila was also evident among the various racial groups. An increased abundance of Micrococcus was also evident in AA and HIS women compared to the CA women. The detection level of Rhizobium was higher among the AA ad CA women compared to the HIS women. In addition to the top 10 microbes, a unique niche of 27 microbes was identified exclusively in women with a histopathological diagnosis of CIN. Among these microbes, a group of 8 microbiota; Rubellimicrobium, Podobacter, Brevibacterium, Paracoccus, Atopobium, Brevundimonous, Comamonous, and Novospingobium was detected only in the CIN lesions obtained from AA and CA women. CONCLUSIONS Microbial dysbiosis in the cervical epithelium represented by an increased ratio of potentially pathogenic to beneficial microbes may be associated with increased CC risk disparities. Developing a race-specific reliable panel of microbial markers could be beneficial for CC risk assessment, disease prevention, and/or therapeutic guidance.

Abstract
BACKGROUND The Mycobacterium genus encompasses at least 192 named species, many of which cause severe diseases such as tuberculosis. Non-tuberculosis mycobacteria (NTM) can also infect humans and animals. Some are of emerging concern because they show high resistance to commonly used antibiotics while others are used and evaluated in bioremediation or included in anticancer vaccines. RESULTS We provide the genome sequences for 114 mycobacterial type strains and together with 130 available mycobacterial genomes we generated a phylogenetic tree based on 387 core genes and supported by average nucleotide identity (ANI) data. The 244 genome sequences cover most of the species constituting the Mycobacterium genus. The genome sizes ranged from 3.2 to 8.1 Mb with an average of 5.7 Mb, and we identified 14 new plasmids. Moreover, mycobacterial genomes consisted of phage-like sequences ranging between 0 and 4.64% dependent on mycobacteria while the number of IS elements varied between 1 and 290. Our data also revealed that, depending on the mycobacteria, the number of tRNA and non-coding (nc) RNA genes differ and that their positions on the chromosome varied. We identified a conserved core set of 12 ncRNAs, 43 tRNAs and 18 aminoacyl-tRNA synthetases among mycobacteria. CONCLUSIONS Phages, IS elements, tRNA and ncRNAs appear to have contributed to the evolution of the Mycobacterium genus where several tRNA and ncRNA genes have been horizontally transferred. On the basis of our phylogenetic analysis, we identified several isolates of unnamed species as new mycobacterial species or strains of known mycobacteria. The predicted number of coding sequences correlates with genome size while the number of tRNA, rRNA and ncRNA genes does not. Together these findings expand our insight into the evolution of the Mycobacterium genus and as such they establish a platform to understand mycobacterial pathogenicity, their evolution, antibiotic resistance/tolerance as well as the function and evolution of ncRNA among mycobacteria.

Abstract
Mitochondria are pivotal organelles that govern cellular energy production through the oxidative phosphorylation system utilizing five respiratory complexes. In addition, mitochondria also contribute to various critical signaling pathways including apoptosis, damage-associated molecular patterns, calcium homeostasis, lipid, and amino acid biosynthesis. Among these diverse functions, the energy generation program oversee by mitochondria represents an immaculate orchestration and functional coordination between the mitochondria and nuclear encoded molecules. Perturbation in this program through respiratory complexes' alteration results in the manifestation of various mitochondrial disorders and malignancy, which is alarmingly becoming evident in the recent literature. Considering the clinical relevance and importance of this emerging medical problem, this review sheds light on the timing and nature of molecular alterations in various respiratory complexes and their functional consequences observed in various mitochondrial disorders and human cancers. Finally, we discussed how this wealth of information could be exploited and tailored to develop respiratory complex targeted personalized therapeutics and biomarkers for better management of various incurable human mitochondrial disorders and cancers.

Abstract
Abstract
Study question
Are couples presenting to infertility clinics actually infertile, or is there an undiagnosed underlying sexual dysfunction whose treatment can lead to natural conception avoiding the need for assisted reproductive techniques?
Summary answer
All couples presenting with infertility should be asked about sexual function. If sexual dysfunction is diagnosed, a signicant proportion can achieve pregnancy without assisted reproduction
What is known already
Infertility is defined as the inability to conceive after one year of frequent and regular unprotected sexual intercourse (SI). Although sexual histories are a key part of primary care screening guidelines for infertility, they are often overlooked during the infertility work-up. It is postulated that a large proportion of couples presenting to infertility clinics have underlying sexual dysfunction. Treatment through specialist counselling for couples with sexual dysfunction can help achieve pregnancy, negating the need for complex assisted reproductive techniques such as intravaginal insemination (IVI) and intrauterine insemination (IUl).
Study design, size, duration
108 couples were recruited from a national fertility clinic. The duration of the study was 3.5 years, from January 2016 to August 2019. The study was based primarily on surveys, where diagnostic work-up for infertility included tools for measuring sexual dysfunction, such as the IIEF-15 questionnaire. Our objectives were to find the extent of improvement of SI before and after specialist referral, and the time to conceive (TTC) in those with and without sexual dysfunction.
Participants/materials, setting, methods
Couples who never had successful completion of SI (despite producing an ejaculate sample) prior to clinic attendance were included. Treatment via specialist referral was then offered to these patients.
Data were analysed to compare outcomes between those who subsequently had successful SI (“Group A”) and those who had not had successful SI (“Group B”). Both groups were counselled for fertility treatments, such as IVI and IUI. TTC between the groups was analysed using Kaplan-Meier analysis
Main results and the role of chance
Out of 2057 couples presenting to the Infertility Clinic, 128 (5.98%) had never had successful SI. From this, 108 couples were included in the study. Two-thirds of couples revealed sexual difficulties at the beginning of the initial consultation. In men, erectile dysfunction was the predominant cause (70.4%, n = 76). In women, dyspareunia was the leading problem (18.2%, N = 20). Fertility investigations, which included hormone profiles, revealed normal results in most cases.
Treatment via referral to specialist sexual counselling was offered to all couples. Only 33 couples reported successful SI during subsequent visits (Group A). 13 of these 33 couples went on to conceive (11 naturally, 1 by IUI and 1 by IVI). The rest (n = 75), who had no improvement (Group B), had a significantly longer duration of sexual dysfunction, which was also more severe. Out of these 75 couples, 8 conceived (0 naturally, 6 by IVI, and 2 by IUI).The IIEF-15 scores (index for sexual dysfunction) between groups A and B were 10.72 ± 4.28 vs. 8 ± 4.73, P-value 0.0142. Group A couples (less severe sexual dysfunction) conceived earlier than Group B (mean duration 27.2 weeks vs. 48.8 weeks log-rank P value <0.001).
Limitations, reasons for caution
The main limitations of this study include a small sample size and a small minority of couples refusing to undergo specialist counselling despite having sexual difficulties as they were only interested in assisted reproductive interventions such as IUl and IVI. These limitations hinder the internal/external validity of the study.
Wider implications of the findings
All couples presenting with infertility should be asked about sexual function. If sexual dysfunction is diagnosed, a signicant proportion can be helped to achieve pregnancy without assisted reproduction. In the cases of couples with persistent sexual difficulty, assisted reproductive techniques like IUI and IVI give a reasonable pregnancy rate.

Abstract
Abstract
Study question
Investigate the differences in sexual dysfunction and time to pregnancy between infertile couples pursuing timed intercourse and Regular Intercourse (RI at least twice a week).
Summary answer
TI significantly increased the risk of SD compared to RI for both males and females after adjusting all other contributing factors.
What is known already
Timed Intercourse (TI) involves aligning sexual intercourse to the time around ovulation to increase the chance of conception in couples trying to conceive. Whilst TI is often advocated to increase conception rates and potentially accelerate the time to pregnancy (TTP) for infertile couples, the stressful nature of this approach may be associated with adverse effects such as sexual dysfunction (SD) within the couple.
Study design, size, duration
This prospective cohort study recruited 371 infertile couples who had been trying to conceive for more than a year, presenting to three regional infertility clinics between January 2016 and December 2018. 283 couples pursued TI and 88 couples pursued RI for a year, with all couples having no pre-existing sexual or psychiatric illness, and no medical contraindications to frequent intercourse.
Participants/materials, setting, methods
The SD score of both partners was assessed at the first visit using the validated Arizona Sexual Experiences Scale (ASEX) and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V). TTP was determined using Kaplan Meier Analysis in couples for whom natural conception was possible and no reversible fertility pathology was identified.
Main results and the role of chance
Timed Intercourse (TI) involves aligning sexual intercourse to the time around ovulation to increase the chance of conception in couples trying to conceive. Whilst TI is often advocated to increase conception rates and potentially accelerate the time to pregnancy (TTP) for infertile couples, the stressful nature of this approach may be associated with adverse effects such as sexual dysfunction (SD) within the couple.
TI significantly increased the risk of SD compared to RI for both males (Odds ratio [OR] 15.24, 95% confidence interval [CI] 7.96-29.15) and females (OR 5.52, 95% CI 2.38- 12.78), after adjusting for age, medical disorders, obesity, smoking, cause of infertility, and previous assisted reproductive techniques. TI carried a higher risk of developing erectile dysfunction, premature ejaculation, male hypoactive sexual dysfunction, female sexual interest-arousal disorder, and female orgasmic disorder. The TTP for natural conception was similar between TI and RI (p = 0.1365).
Limitations, reasons for caution
TI, a well-known strategy for increasing conception rates, did not improve time to natural conception compared to regular sexual intercourse. In contrast, the risk of sexual dysfunction in both men and women was significantly higher in TI, compared with RI.
Wider implications of the findings
This large study raises the question of effectiveness of the long-held belief that TI (intercourse limited around the ovulation-time, based on different methods of ovulation-prediction) improves pregnancy outcomes.

Abstract
Abstract
Prostate cancer (PCa) is the most diagnosed non-cutaneous malignancy and the second leading cause of cancer-related death in American men. Significant racial disparities also exist in incidence and clinical outcome. African American (AA) men are nearly two times more likely to be diagnosed with PCa and have more than twice mortality rate than their Caucasian American (CA) counterparts. Despite an early diagnosis in majority of the cases, about one-third patients face biochemical recurrence following local therapy, with a likelihood of developing distant metastasis. Gleason score used as a prognosticator exhibits discrepancy between AA and CA men highlighting the need for better predictive markers. We previously demonstrated functional significance of MYB in PCa growth, aggressiveness, and castration-resistance. We also showed a role of MYB in sustained androgen receptor (AR) signaling under androgen-deprived condition and prostate-specific antigen (PSA) expression. Here, we studied the expression of MYB in PCa by immunohistochemistry and examined if it varied between AA and CA PCa cases and had any clinicopathological correlation. A total of 105 PCa [CA (n=50) and AA (n=55)] cases with available clinicopathologic data were included. MYB expression was also studied in adjacent benign prostatic hyperplasia (BPH) and high-grade prostate intraepithelial neoplastic (HGPIN) lesions. Stained slides were scanned and digitally analyzed for the measurement of percent positivity (0-100%) and staining intensity (1+, 2+ and 3+). Significant overexpression of MYB (p<0.0001) was reported in PCa relative to HGPIN and BPH. PCa predominantly exhibited moderate to strong staining, compared to weak to moderate staining with low precent positivity rate in HGPIN and weak MYB staining with low percent positivity in BPH. A significantly higher expression of MYB (p<0.0001) was noted in high Gleason score (8-9) PCa, compared to the low-medium Gleason score (≤7) PCa. Interestingly, MYB expression was significantly (p= 0.024) higher in AA PCa than CA PCa in overall and Gleason score wise comparisons. Correlation analysis of MYB showed its inverse association with time to BCR (r =-0.467, 95% CI=-0.675 to -0.190, p=0.002). Altogether, our findings establish MYB as a potentially useful biomarker for PCa diagnosis and prognosis and provide clinical support to our prior findings on the pathobiological role of MYB in PCa.

Abstract
Abstract
Lung cancer killed 1.8 million people globally in 2020. In the United States, there will be over 235,760 cases of lung cancer with an estimated death of 131,880 individuals in 2021. Despite significant improvement in multimodal therapeutic approaches, overall 5-year survival rate is only 21.7%. Lung cancer appears to be mitochondria enriched cancer, however, alteration pattern of hallmark molecular pathways associated with diverse mitochondrial functions remain largely unknown in lung tumorigenesis. Utilizing high-throughput genomic profiling, we identified altered copy number of a panel of 40 mitochondria targeted molecules in primary lung cancer patients and their histologically normal appearing follow up mucosal biopsies. These altered molecules are critical components of the mitochondrial protein carrier, OXPHOS, stress response, amino acid metabolism and apoptosis pathways. This finding suggests for clonal genetic relationship between multifocal lesions and potential role of these alterations in the evolution of second primary tumors, which is an existing problem among lung cancer patients. The Human Cancer Genome Atlas database was utilized to further assess the mRNA expression pattern of these 40 molecules and determine their clinico-pathological correlations. Immunohistochemistry and digital pathology system based evaluations were performed to validate expression pattern of key altered molecules. We identified overexpression of various critical mitochondria pathway molecules including AARS2, AGMAT, SDHA, NDUFB7, LONP1, DGUOK, MRM1 and GCAT in both lung adenocarcinomas (LUAD) and squamous cell carcinomas (LUSC), predicting poor prognosis. Significant loss of expression of ACSF2, ACSS1, MTCH1, SLC25A4, ACAD8 and NAGS was evident in both adenocarcinoma and squamous cell carcinoma subtypes. Molecular characterization of both LUAD and LUSC tumor subtypes identified significant association of various key molecules including ACAD8, AGMAT, DGUOK and NDUFAB1 with proximal-inflammatory, proximal-proliferative and terminal respiratory unit pathways in LUAD; and an association of DGUOK, MDH2, MRM1 and MRPL10 with basal, classical, primitive and secretory pathways in LUSC. Significant loss of SLC25A4 protein expression was evident in lung cancer tissues, which predicted poor survival of the lung cancer patients. Capturing the compendium of hallmark mitochondrial alterations in lung tumorigenesis may open up novel avenues for therapeutic and biomarker interventions to improve the overall survival of the lung cancer patients.

Abstract
Abstract
Tobacco smoke (TS) is one of the most prominent risk factors for lung and several other malignancies. Toxic chemicals present in TS induce DNA damage leading to carcinogenic mutations. Moreover, TS can also cause epigenetic and gene expression changes in tumor and other cells of the tumor microenvironment, especially through its addictive component nicotine. We and others have reported that nicotine promotes tumor angiogenesis via its direct impact on the endothelial cells or by altering the cancer cell secretome. In this study, we wanted to explore the association of smoking habits with the differential expression of angiogenesis-related genes in lung adenocarcinoma (LUAD) patients. Gene Set Enrichment Analysis (GSEA) identified a set of 48 angiogenesis-related genes that were surveyed for differential expression in smoker versus non-smoker patients in The Cancer Genomic Atlas (TCGA) database using an interactive web application, UALCAN. Gender and age of the LUAD patients were considered as confounding variables since patients of different age groups and gender can have biological and physiological differences, which could influence gene expression regardless of the smoking habits. We identified a total of fourteen differentially-expressed genes, of which four (HTATIP2, NCL, SPHK1, and VEGFA) were overexpressed and ten (AGGF1, AMOT, C1GALT1, ERAP1, NPR1, PML, RNH1, SHH, SPINL5, and TNFSF12) were downregulated in LUAD of smokers than those of non-smokers. Five of the differentially-expressed genes (HTATIP2, NCL NPR1, PML, and TNFSF12) exhibited significantly different transcript levels in males versus females and three (SPHK1, AGGF1, and SPINK5) showed varying pattern of expression in LUAD of different age group patients. Literature survey found prior published evidence for an association of two of the fourteen differentially expressed genes (NCL and NPR) with nicotine exposure. Together, our findings identify smoking-associated angiogenic gene signatures that could be potential effectors of nicotine signaling that promotes cancer angiogenesis and should be validated further by conducting laboratory investigations.

Abstract
COVID has posed several challenges for higher education. There is a rise in blended teaching and learning models that can improve the quality of education, observed Raman. Classroom interaction vital in quality of education is affected by power distance between the teacher and students, states Kasuya. Much research has been done on blended learning but hardly any on the role of power distance in blended learning in higher education, specifically post COVID. Keeping in mind the growing significance of blended learning shortly, it becomes strategically important to understand the role of power distance in blended learning in higher education post-COVID-19. This research paper tries to address the research gap. The study is exploratory, exploring the role of power distancing in blended learning formats during post-COVID-19. The findings indicate that there is a relationship between power distance and the autonomy of an individual. The higher the power distance between a teacher and a student from the teacher’s perspective, it becomes teacher-centred learning. So blended learning with the best of low power distances in terms of the media and delivery mechanism of offline and online ensures the mitigation of power between the teacher and the taught. The research will help the universities create a perfect blended learning format that enhances the quality of higher education. Due to the paucity of time and resources and a ban on respondent interaction due to pandemics, this research is based on secondary data analysis.

Abstract
INTRODUCTION Marine microalgae protein has better solubility and digestibility than other protein-based feeds. Apart from protein, high-value biomolecules have an immense potential to enhance the quality of feed, but knowledge about them is scarce. OBJECTIVE Marine microalga Picochlorum sp. biomass molecular characterisation along with commonly used protein feed such as fishmeal and soymeal for potential feed ingredients. METHODOLOGY Liquid chromatography coupled with mass spectrometry (LC-MS) was used for biomolecular characterisation. The correlation of biomolecules sets was evaluated using principal component analysis (PCA) and heatmap clustering. RESULTS LC-MS identified 116 biomolecules cumulatively among microalga, fishmeal, and soymeal that includes fatty acids, acylglycerols, vitamins, sterols, pigments, nucleotides, unique amino acids, amines, sugars and miscellaneous. These 116 biomolecules were screened based on their functional importance as feed ingredients. Among the different sets of biomolecules, microalga contained a more diverse set of fatty acids, pigments, sterols, and vitamins than acylglycerols, unique amino acids, nucleotides, and sugars. Fishmeal contained a more diverse set of acylglycerols, unique amino acids, nucleotides, and amines, while soymeal contained the highest number of sugars and miscellaneous biomolecules. The PCA confirmed the significance level (P > 95%) and heatmap clustering showed the diversity and relatedness of biomolecules among the microalga, fishmeal, and soymeal. CONCLUSION This study showed that the marine microalga Picochlorum sp. biomass has a rich source of biomolecules and could complement fishmeal or soymeal in feed and is also sustainable and economical as compared to fishmeal and soymeal.

Abstract
A discrete degree of freedom can be engineered to match the Hamiltonian of particles moving in a real-space lattice potential. Such synthetic dimensions are powerful tools for quantum simulation because of the control they offer and the ability to create configurations difficult to access in real space. Here, in an ultracold 84Sr atom, we demonstrate a synthetic-dimension based on Rydberg levels coupled with millimeter waves. Tunneling amplitudes between synthetic lattice sites and on-site potentials are set by the millimeter-wave amplitudes and detunings respectively. Alternating weak and strong tunneling in a one-dimensional configuration realizes the single-particle Su-Schrieffer-Heeger (SSH) Hamiltonian, a paradigmatic model of topological matter. Band structure is probed through optical excitation from the ground state to Rydberg levels, revealing symmetry-protected topological edge states at zero energy. Edge-state energies are robust to perturbations of tunneling-rates that preserve chiral symmetry, but can be shifted by the introduction of on-site potentials. Synthetic dimensions, states of a system engineered to act as if they were a reconfigurable extra spatial dimension, have been demonstrated with different systems previously. Here the authors create a synthetic dimension using Rydberg atoms and configure it to support topological edge states.

Abstract
Rapidly exhausting fossil fuels combined with the ever-increasing demand for energy led to an ongoing search for alternative energy sources to meet the transportation, manufacturing, domestic and other energy demands of the grown population. Microalgae are at the forefront of alternative energy research due to their significant potential as a renewable feedstock for biofuels. However, microalgae platforms have not found a way into industrial-scale bioenergy production due to various technical and economic constraints. The present review provides a detailed overview of the challenges in microalgae production processes for bioenergy purposes with supporting techno-economic assessments related to microalgae cultivation, harvesting and downstream processes required for crude oil or biofuel production. In addition, biorefinery approaches that can valorize the by-products or co-products in microalgae production and enhance the techno-economics of the production process are discussed.

Abstract
Over the years, we have made considerable progress in our understanding of the biology of various cancers leading to advancements in their management strategies. Consequently, we have witnessed steady improvements in survival rates of cancer patients post-diagnosis. The progress; however, has been slow for some cancer types and the advances in cancer care have not benefited all the communities equally in the United States. The state of Alabama has one of the most diverse demographics in the country and as a result, we witness significant health disparities among our populations. Breast and cervical cancers are the two major cancer types that disparately affect the women in our state. Here, we describe the extent of disparities in the diagnosis and death rates from these cancers in the state of Alabama and discuss potential underlying causes affecting the health outcomes. We also discuss ongoing efforts undertaken to reduce the disparity gaps and provide a perspective for addressing these disparities more effectively.

Abstract
Till date, the existing understanding of negative differential resistance (NDR) is obtained from metal-ferro-metal-insulator-semiconductor (MFMIS) FET, and it has been utilized for both MFMIS and metal-ferro-insulator-semiconductor (MFIS) based NCFETs. However, in MFIS architecture, the ferroelectric capacitance (CFE) is not a lumped capacitance. Therefore, for MFIS negative capacitance (NC) devices, the physical explanation which governs the NDR mechanism needs to be addressed. In this work, for the first time, we present the first principle explanation of the NDR effect in MFIS NC FDSOI. We found that the output current variation with the drain to source voltage (VDS), (i.e.gds) primarily depends upon two parameters: (a)VDSdependent inversion charge gradient (∂n/∂VDS); (b)VDSsensitive electron velocity (∂v/∂VDS), and the combined effect of these two dependencies results in NDR. Further, to mitigate the NDR effect, we proposed the BOX engineered NC FDSOI FET, in which the buried oxide (BOX) layer is subdivided into the ferroelectric (FE) layer and the SiO2layer. In doing so, the inversion charge in the channel is enhanced by the BOX engineered FE layer, which in turn mitigates the NDR and a nearly zerogdswith a minimal positive slope has been obtained. Through well-calibrated TCAD simulations, by utilizing the obtained positivegds, we also designed aVDSindependent constant current mirror which is an essential part of analog circuits. Furthermore, we discussed the impact of the FE parameter (remanent polarization and coercive field) variation on the device performances. We have also compared the acquired results with existing literature on NC-based devices, which justifies that our proposed structure exhibits complete diminution of NDR, thus enabling its use in analog circuit design.

Abstract
Resistance to platinum-based chemotherapy is a major clinical challenge in ovarian cancer, contributing to the high mortality-to-incidence ratio. Management of the platinum-resistant disease has been difficult due to diverse underlying molecular mechanisms. Over the past several years, research has revealed several novel molecular targets that are being explored as biomarkers for treatment planning and monitoring of response. The therapeutic landscape of ovarian cancer is also rapidly evolving, and alternative therapies are becoming available for the recurrent platinum-resistant disease. This review provides a snapshot of platinum resistance mechanisms and discusses liquid-based biomarkers and their potential utility in effective management of platinum-resistant ovarian cancer.

Abstract
Microalgae offer a promising source of biofuel and a wide array of high-value biomolecules. Large-scale cultivation of microalgae at low density poses a significant challenge in terms of water management. High-density microalgae cultivation, however, can be challenging due to biochemical changes associated with growth dynamics. Therefore, there is a need for a biomarker that can predict the optimum density for high biomass cultivation. A locally isolated microalga Cyanobacterium aponinum CCC734 was grown with optimized nitrogen and phosphorus in the ratio of 12:1 for sustained high biomass productivity. To understand density-associated bottlenecks secretome dynamics were monitored at biomass densities from 0.6 ± 0.1 to 7 ± 0.1 g/L (2 to 22 OD) in batch mode. Liquid chromatography coupled with mass spectrometry identified 880 exometabolites in the supernatant of C. aponinum CCC734. The PCA analysis showed similarity between exometabolite profiles at low (4 and 8 OD) and mid (12 and 16 OD), whereas distinctly separate at high biomass concentrations (20 and 22 OD). Ten exometabolites were selected based on their role in influencing growth and are specifically present at low, mid, and high biomass concentrations. Taking cues from secretome dynamics, 5.0 ± 0.5 g/L biomass concentration (16 OD) was optimal for C. aponinum CCC734 cultivation. Further validation was performed with a semi-turbidostat mode of cultivation for 29 days with a volumetric productivity of 1.0 ± 0.2 g/L/day. The secretomes-based footprinting tool is the first comprehensive growth study of exometabolite at the molecular level at variable biomass densities. This tool may be utilized in analyzing and directing microalgal cultivation strategies and reduction in overall operating costs.

Abstract
Heavy metal (HM) pollution is a serious agro-economic concern and algae can be used as one of the bioremediating agents as it can grow in different water bodies. In this study, the Scenedesmus acutus and Chlorella pyrenoidosa were exposed to various concentrations of Pb2+ for 96 h and a multidimensional toxicity assessment has been performed by pulse amplitude modulation technique and Fourier transform infrared spectroscopy (FTIR). High-angle annular dark-field scanning transmission electron microscopy coupled energy dispersive spectroscopy (HAADF-S/TEM-EDS) detected intracellular localization of Pb2+ , thus confirming algal bio-accumulation abilities. Sensitivity assay demonstrated that 500 and 400 ppm of Pb2+ as minimum inhibitory concentrations (MIC50) for S. acutus and C. pyrenoidosa, respectively, which inhibited growth (OD) by >50% in 96 h. During bioremoval studies, S. acutus and C. pyrenoidosa were found to remove ∼52 and ∼32% of total Pb2+ , respectively. The particulate analysis of Pb2+ by ICP-OES showed >99.5% biosorption capacity by both the species. The biomass characterization by FTIR showed the involvement of various cell wall functional groups such as hydroxyl, alkane, and C=C groups in the biosorption of Pb2+ by both the species. The noninvasive chlorophyll fluorescence techniques provide a quick insight on heavy metal stress and can be adapted as a rapid detection tool to study the Pb2+ stress. S. acutus strain showed higher tolerance and higher bioremoval capacity than C. pyrenoidosa. However, both the species can be exploited for biosorption of Pb2+ from aquatic streams as an alternative way for low cost Pb2+ recovery systems.

Abstract
Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 pandemic, has infected more than 179 million people worldwide. Testing of infected individuals is crucial for identification and isolation, thereby preventing further spread of the disease. Presently, Taqman™ Reverse Transcription Real Time PCR is considered gold standard, and is the most common technique used for molecular testing of COVID-19, though it requires sophisticated equipments, expertise and is also relatively expensive. Objective Development and optimization of an alternate molecular testing method for the diagnosis of COVID-19, through a two step Reverse Transcription Loop-mediated isothermal AMPlification (RT-LAMP). Results Primers for LAMP were carefully designed for discrimination from other closely related human pathogenic coronaviruses. Care was also taken that primer binding sites are present in conserved regions of SARS-CoV2. Our analysis shows that the primer binding sites are well conserved in all the variants of concern (VOC) and variants of interest (VOI), notified by World Health Organization (WHO). These lineages include B.1.1.7, B.1.351, P.1, B.1.617.2, B.1.427/B.1.429, P.2, B.1.525, P.3, B.1.526 and B.1.617.1. Various DNA polymerases with strand displacement activity were evaluated and conditions were optimized for LAMP amplification and visualization. Different LAMP primer sets were also evaluated using synthetic templates as well as patient samples. Conclusion In a double blind study, the RT-LAMP assay was validated on more than 150 patient samples at two different sites. The RT-LAMP assay appeared to be 89.2% accurate when compared to the Taqman™ rt-RT-PCR assay.

Abstract
The COMPASS Collaboration experiment recently discovered a new isovector resonancelike signal with axial-vector quantum numbers, the a_{1}(1420), decaying to f_{0}(980)π. With a mass too close to and a width smaller than the axial-vector ground state a_{1}(1260), it was immediately interpreted as a new light exotic meson, similar to the X, Y, Z states in the hidden-charm sector. We show that a resonancelike signal fully matching the experimental data is produced by the decay of the a_{1}(1260) resonance into K^{*}(→Kπ)K[over ¯] and subsequent rescattering through a triangle singularity into the coupled f_{0}(980)π channel. The amplitude for this process is calculated using a new approach based on dispersion relations. The triangle-singularity model is fitted to the partial-wave data of the COMPASS experiment. Despite having fewer parameters, this fit shows a slightly better quality than the one using a resonance hypothesis and thus eliminates the need for an additional resonance in order to describe the data. We thereby demonstrate for the first time in the light-meson sector that a resonancelike structure in the experimental data can be described by rescattering through a triangle singularity, providing evidence for a genuine three-body effect.

Abstract
With increasing demand for resources to achieve global food-water-energy nexus and rapid decline in land-based sources, oceans represent both solution and boost to sustainable environment and economy. In addition to fundamental part of earth's ecosystem for uncatalogued diversity of life, oceans are undervalued economy powerhouse with gross marine product value. With sustainable management of existing assets including shipping, transportation, manufacturing, fisheries, tourism and exploration of new business like marine biotechnology and renewable energy, the ocean or blue economy has potential to fulfill sustainable development goals (SDG). In spite of recognition of blue economy as a new economic frontier, investments by existing industries and emergence of new ones are limited and less known, hence require more in depth attention and scientific understanding. In the present study, authors present a systematic comparative assessment of blue economy sectors with distinct challenges and strategies to be further explored and implemented for industrial deployment. The conceptualization of integrated routes of bio(economy) by the current study can act as gateway for key stakeholders, i.e. governance, bluepreneurs (scientists and industries) to prioritize technologies for sustainable applications of marine resources.

Abstract
Microalgae are rapidly evolving alternative ingredients in food and feed. Desirable nutritional and functional qualities make them high potential sources of feed ingredients. Certain microalgae species are known to accumulate large amounts of protein, containing all essential amino acids while some species contain essential fatty acids and bioactive compounds hence offering several possible health benefits. However, successful inclusion of microalgae-based products in feed requires a clear understanding of physiological responses and microbiota of animals receiving microalgae diets. In this review, key microalgae-based feed ingredients and their effect on gut microbiome and immunomodulatory responses of microalgae fed animals, with a focus on aquatic species will be discussed.

Abstract
Mitochondria are highly dynamic, maternally inherited cytoplasmic organelles, which fulfill cellular energy demand through the oxidative phosphorylation system. Besides, they play an active role in calcium and damage-associated molecular patterns signaling, amino acid, and lipid metabolism, and apoptosis. Thus, the maintenance of mitochondrial integrity and homeostasis is extremely critical, which is achieved through continual fusion and fission. Mitochondrial fusion allows the transfer of gene products between mitochondria for optimal functioning, especially under metabolic and environmental stress. On the other hand, fission is crucial for mitochondrial division and quality control. The imbalance between these two processes is associated with various ailments such as cancer, neurodegenerative and cardiovascular diseases. This review discusses the molecular mechanisms that control mitochondrial fusion and fission and how the disruption of mitochondrial dynamics manifests into various disease conditions.

Abstract
Bacterial nanocellulose production is gaining popularity owing to its applications in food, cosmetics and medical industry. Three Acetobacter strains isolated from organic waste and fermented tea were identified using 16S rDNA sequencing and their ability to produce nanocellulose was studied. Strain isolated from Kombucha has 99% homology with Komagataeibacter rhaeticus DSM 16663 T. This is the first report where nanocellulose productivity of this strain with different carbon sources such as glucose, glycerol, fructose and sucrose has been studied. 1% glycerol was found to be optimal concentration, with up to 69% of the utilized carbon converted to nanocellulose. Maximum productivity of 4.5 g/L of bacterial nanocellulose was obtained. Average nitrogen and phosphorus consumption rate was 45 mg/L/day each. Physical properties such as crystallinity, fibril dimensions, and glass transition temperature were studied. Bacterial cellulose was 80% crystalline when glycerol and glucose were used as carbon source and 73% for fructose and sucrose. Renewable materials such as bacterial cellulose with their unique properties are the future for applications in the field of cosmetics, composite and wound care.

Abstract
Cadmium (Cd) contamination in different water bodies is a matter of serious concern, as it can cause biomagnification in our food chain up to several trophic levels. In this study, Cd toxicity was investigated in the micro-algae Chlorella pyrenoidosa and Scenedesmus acutus exposed to various concentrations of Cd for 96 h. The inhibitory and toxic effects of Cd2+ on growth and photosynthetic parameters of algae were demonstrated. The bioremediation potentials of these algae were investigated and bioremoval mechanisms were confirmed using qualitative electron microscopic assay such as scanning/transmission electron microscope (S/TEM). The photochemical quenching (Fv/Fm), quantum yield (YII), relative electron transfer rate (rETR) and non-photochemical quenching (NPQ) were inhibited significantly and reduced by ≥ 50% of the control at MIC 50 values. The C. pyrenoidosa and S. acutus biomass have shown 30% and 20% reduction in carbon content and 10% and 12% reduction in nitrogen content at MIC50 values of Cd2+ treatment, respectively. During bioremoval studies, C. pyrenoidosa and S. acutus have shown 45.45% and 57.14% Cd2+ removal of Cd2+ from initial concentration of 1.5 ppm. Out of total cadmium removal C. pyrenoidosa was reported 3% bioaccumulation and 97% biosorption. Whereas S. acutus showed 1.5% accumulation and 98.5% biosorption. The S/TEM images showed the surface accumulation and bioaccumulation of cadmium inside the cytoplasm, vacuoles, and chloroplast. Thus cultivating C. pyrenoidosa and S. acutus would be beneficial in Cd2+ contaminated water bodies as they serve the dual purpose by Cd remediation and algal biomass production.

Abstract
In oral-cancer, the number of tumor-infiltrating lymphocytes (TILs) associates with improved survival, yet the prognostic value of the cellular composition and localization of TILs is not defined. We quantified densities, localizations, and cellular networks of lymphocyte populations in 138 patients with T1-T2 primary oral-tongue squamous cell carcinoma treated with surgical resections without any perioperative (chemo)radiotherapy, and correlated outcomes to overall survival (OS). Multiplexed in-situ immunofluorescence was performed for DAPI, CD4, CD8, CD20, and pan-cytokeratin using formalin-fixed paraffin-embedded sections, and spatial distributions of lymphocyte populations were assessed in the tumor and stroma compartments at the invasive margin (IM) as well as the center of tumors. We observed a high density of CD4, CD8, and CD20 cells in the stroma compartment at the IM, but neither lymphocyte densities nor networks as single parameters associated with OS. In contrast, assessment of two contextual parameters within the stroma IM region of tumors, i.e., the number of CD20 cells within 20 µm radii of CD20 and CD4 cells, termed the CD20 Cluster Score, yielded a highly significant association with OS (HR 0.38; p = .003). Notably, the CD20 Cluster Score significantly correlated with better OS and disease-free survival in multivariate analysis (HR 0.34 and 0.47; p = .001 and 0.019) as well as with lower local recurrence rate (OR: 0.13; p = .028). Taken together, our study showed that the presence of stromal B-cell clusters at IM, in the co-presence of CD4 T-cells, associates with good prognosis in early oral-tongue cancer patients.

Abstract
Iron deficiency anemia (IDA) is probably the most ignored situation in the world of malnutrition-largely due to its slow progression. Multiple reasons can be attributed as the cause of IDA, which is not limited to any specific region or population; therefore, making it a matter of global concern. Despite the human body's ability to absorb and conserve iron stores, the gradual loss due to various physiological conditions leads to net deficiency of iron. Countless commercial iron supplements are available, but at given physiological conditions, almost all of these "Bio-not-available" iron forms quite often become ineffective. World Health Organization and other government bodies have jointly developed health advisories and tried to developed nutrition supplements several times in the last two decades. IDA, when combined with other disease conditions, becomes a life-threatening situation. At the same time, an overdose of iron could also be very harmful to the body. Therefore, it is important to deal with this situation with caution. This article covers iron metabolism, available options for iron supplementation, regulatory aspects and strategies to prevent IDA.

Abstract
Ovarian cancer (OC) is the most lethal gynecological malignancy among women worldwide. In most cases, it is diagnosed late at an advanced stage and does not respond well to existing therapies leading to its poor prognosis. In addition, other factors including epidemiological, complex histological diversity, multiple molecular alterations, and overlapping signaling pathways are also important contributors to poor disease outcome. Efforts have continued to develop a deeper understanding of the molecular pathogenesis and altered signaling nodes that provide hope for better clinical management through the development of novel approaches for early diagnosis, disease subtyping, prognosis, and therapy. In this chapter, we provide a detailed overview of OC and its histological subtypes and discuss prevalent molecular aberrations and active signaling pathways that drive OC progression. We also summarize various diagnostic and prognostic markers and therapeutic approaches currently being employed and discuss emerging findings that hold the potential to change the future course of OC management.

Abstract
Host excessive inflammatory immune response to SARS-CoV-2 infection is thought to underpin the pathogenesis of COVID-19 associated severe pneumonitis and acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). Once an immunological complication like cytokine storm occurs, anti-viral based monotherapy alone is not enough. Additional anti-inflammatory treatment is recommended. It must be noted that anti-inflammatory drugs such as JAK inhibitors, IL-6 inhibitors, TNF-α inhibitors, colchicine, etc., have been either suggested or are under trials for managing cytokine storm in COVID-19 infections. Natural astaxanthin (ASX) has a clinically proven safety profile and has antioxidant, anti-inflammatory, and immunomodulatory properties. There is evidence from preclinical studies that supports its preventive actions against ALI/ARDS. Moreover, ASX has a potent PPARs activity. Therefore, it is plausible to speculate that ASX could be considered as a potential adjunctive supplement. Here, we summarize the mounting evidence where ASX is shown to exert protective effect by regulating the expression of pro-inflammatory factors IL-1β, IL-6, IL-8 and TNF-α. We present reports where ASX is shown to prevent against oxidative damage and attenuate exacerbation of the inflammatory responses by regulating signaling pathways like NF-ĸB, NLRP3 and JAK/STAT. These evidences provide a rationale for considering natural astaxanthin as a therapeutic agent against inflammatory cytokine storm and associated risks in COVID-19 infection and this suggestion requires further validation with clinical studies.

Abstract
Global population is predicted to approach 10 billion by 2050, an increase of over 2 billion from today. To meet the demands of growing, geographically and socio-economically diversified nations, we need to diversity and expand agricultural production. This expansion of agricultural productivity will need to occur under increasing biotic, and environmental constraints driven by climate change. Clustered regularly interspaced short palindromic repeats-site directed nucleases (CRISPR-SDN) and similar genome editing technologies will likely be key enablers to meet future agricultural needs. While the application of CRISPR-Cas9 mediated genome editing has led the way, the use of CRISPR-Cas12a is also increasing significantly for genome engineering of plants. The popularity of the CRISPR-Cas12a, the type V (class-II) system, is gaining momentum because of its versatility and simplified features. These include the use of a small guide RNA devoid of trans-activating crispr RNA, targeting of T-rich regions of the genome where Cas9 is not suitable for use, RNA processing capability facilitating simpler multiplexing, and its ability to generate double strand breaks (DSB) with staggered ends. Many monocot and dicot species have been successfully edited using this Cas12a system and further research is ongoing to improve its efficiency in plants, including improving the temperature stability of the Cas12a enzyme, identifying new variants of Cas12a or synthetically producing Cas12a with flexible PAM sequences. In this review we provide a comparative survey of CRISPR-Cas12a and Cas9, and provide a perspective on applications of CRISPR-Cas12 in agriculture.

Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR) - Cas associated protein 9 (Cas9) system is very precise, efficient and relatively simple in creating genetic modifications at a predetermined locus in the genome. Genome editing with Cas9 ribonucleoproteins (RNPs) has reduced cytotoxic effects, off-target cleavage and increased on-target activity and the editing efficiencies. The unicellular alga Chlamydomonas reinhardtii is an emerging model for studying the production of high-value products for industrial applications. Development of C. reinhardtii as an industrial biotechnology host can be achieved more efficiently through genetic modifications using genome editing tools. We made an attempt to target MAA7 gene that encodes the tryptophan synthase β-Subunit using CRISPR-Cas9 RNPs to demonstrate knock-out and knock-in through homology-dependent repair template at the target site. In this study, we have demonstrated targeted gene knock-out in C. reinhardtii using programmed RNPs. Targeted editing of MAA7 gene was confirmed by sequencing the clones that were resistant to 5-Fluoroindole (5-FI). Non-homologous end joining (NHEJ) repair mechanism led to insertion, deletion, and/or base substitution in the Cas9 cleavage vicinity, encoding non-functional MAA7 protein product (knock-out), conferring resistance to 5-FI. Here, we report an efficient protocol for developing knock-out mutants in Chlamydomonas using CRISPR-Cas9 RNPs. The high potential efficiency of editing may also eliminate the need to select mutants by phenotype. These research findings would be more likely applied to other green algae for developing green cell factories to produce high-value molecules.

Abstract
COVID-19 pandemic posed an unprecedented threat to global public health and economies. There is no effective treatment of the disease, hence, scaling up testing for rapid diagnosis of SARS-CoV-2 infected patients and quarantine them from healthy individuals is one the best strategies to curb the pandemic. Establishing globally accepted easy-to-access diagnostic tests is extremely important to understanding the epidemiology of the present pandemic. While nucleic acid based tests are considered to be more sensitive with respect to serological tests but present gold standard qRT-PCR-based assays possess limitations such as low sample throughput, requirement for sophisticated reagents and instrumentation. To overcome these shortcomings, recent efforts of incorporating LAMP-based isothermal detection, and minimizing the number of reagents required are on rise. CRISPR based novel techniques, when merge with isothermal and allied technologies, promises to provide sensitive and rapid detection of SARS-CoV-2 nucleic acids. Here, we discuss and present compilation of state-of-the-art detection techniques for COVID-19 using CRISPR technology which has tremendous potential to transform diagnostics and epidemiology.

Abstract
PURPOSE OF REVIEW To investigate the association between the olfactory dysfunction and the more typical symptoms (fever, cough, dyspnoea) within the Sars-CoV-2 infection (COVID-19) in hospitalized and non-hospitalized patients. RECENT FINDINGS PubMed, Scopus and Web of Science databases were reviewed from May 5, 2020, to June 1, 2020. Inclusion criteria included English, French, German, Spanish or Italian language studies containing original data related to COVID19, anosmia, fever, cough, and dyspnoea, in both hospital and non-hospital settings. Two investigators independently reviewed all manuscripts and performed quality assessment and quantitative meta-analysis using validated tools. A third author arbitrated full-text disagreements. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 11 of 135 studies fulfilled eligibility. Anosmia was estimated less prevalent than fever and cough (respectively rate difference = - 0.316, 95% CI: - 0.574 to - 0.058, Z = - 2.404, p < 0.016, k = 11 and rate difference = - 0.249, 95% CI: - 0.402 to - 0.096, Z = - 3.185, p < 0.001, k = 11); the analysis between anosmia and dyspnoea was not significant (rate difference = - 0.008, 95% CI: - 0.166 to 0.150, Z = - 0.099, p < 0.921, k = 8). The typical symptoms were significantly more frequent than anosmia in hospitalized more critical patients than in non-hospitalized ones (respectively [Q(1) = 50.638 p < 0.000, Q(1) = 52.520 p < 0.000, Q(1) = 100.734 p < 0.000). SUMMARY Patient with new onset olfactory dysfunction should be investigated for COVID-19. Anosmia is more frequent in non-hospitalized COVID-19 patients than in hospitalized ones.
