Abstract
Abstract Germin-like proteins (GLPs) play an important role against various stresses. Vitis vinifera L. genome contains 7 GLPs; many of them are functionally unexplored. However, the computational analysis may provide important new insight into their function. Currently, physicochemical properties, subcellular localization, domain architectures, 3D structures, N-glycosylation & phosphorylation sites, and phylogeney of the VvGLPs were investigated using the latest computational tools. Their functions were predicted using the Search tool for the retrieval of interacting genes/proteins (STRING) and Blast2Go servers. Most of the VvGLPs were extracellular (43%) in nature but also showed periplasmic (29%), plasma membrane (14%), and mitochondrial- or chloroplast-specific (14%) expression. The functional analysis predicted unique enzymatic activities for these proteins including terpene synthase, isoprenoid synthase, lipoxygenase, phosphate permease, receptor kinase, and hydrolases generally mediated by Mn+ cation. VvGLPs showed similarity in the overall structure, shape, and position of the cupin domain. Functionally, VvGLPs control and regulate the production of secondary metabolites to cope with various stresses. Phylogenetically VvGLP1, -3, -4, -5, and VvGLP7 showed greater similarity due to duplication while VvGLP2 and VvGLP6 revealed a distant relationship. Promoter analysis revealed the presence of diverse cis-regulatory elements among which CAAT box, MYB, MYC, unnamed-4 were common to all of them. The analysis will help to utilize VvGLPs and their promoters in future food programs by developing resistant cultivars against various biotic (Erysiphe necator and in Powdery Mildew etc.) and abiotic (Salt, drought, heat, dehydration, etc.) stresses.

Abstract
Increased invasive bloodstream infections caused by multidrug resistant Shigella sonnei were noted in Vancouver, British Columbia, Canada, during 2021-2023. Whole-genome sequencing revealed clonal transmission of genotype 3.6.1.1.2 (CipR.MSM5) among persons experiencing homelessness. Improvements in identifying Shigella species, expanding treatment options for multidrug resistant infections, and developing public health partnerships are needed.

Abstract
Introduction Workplace violence (WPV) is a significant problem for healthcare professionals across the world, regardless of whether they work in developed or developing countries. Studies have shown that in India, up to 75% of doctors have experienced some form of violence in the workplace. The purpose of the present study was to examine the extent of violence against doctors and its impact on patient management. Methodology This cross-sectional study was conducted in a tertiary care hospital in New Delhi in June 2022. A total of 326 resident doctors from six departments were selected using stratified random sampling. Data were collected using a semi-structured interview schedule and a pre-validated questionnaire. Statistical analysis was done using Stata 17, and ethical clearance was obtained from the Institute Ethical Committee. Result Workplace violence was prevalent among healthcare professionals, with 80.4% (95% confidence interval (CI): 75.6%-84.5%) experiencing verbal abuse and 21.7% (95% CI: 17.4%-84.5%) experiencing physical violence. Perceived delays in treatment and patient deaths were the most common causes of violence. Most participants were hesitant to report WPV due to time-consuming reporting processes and a lack of organisational support. WPV had a negative impact on doctors' mental and personal well-being, with 73.3% reporting its negative impact. WPV has led to a decrease in the provision of surgical and medical interventions. Conclusion The study findings suggest that a significant proportion of doctors in a tertiary care hospital in Delhi encounter some form of workplace violence. Despite the high incidence of WPV, reporting of these events remains low due to inadequate support and deficient reporting procedures within healthcare organisations. The negative impact of WPV is not limited to the physicians' psycho-social well-being but extends to their approach to patient care as well. Therefore, taking appropriate actions to prevent WPV is crucial for ensuring the safety and well-being of healthcare professionals and improving patient outcomes.

Abstract
This study was performed to determine the seropositivity of human brucellosis among the patients suffering from pyrexia of unidentified origin. This cross-sectional study was performed at department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from September 2018 to August 2019; among the patients of pyrexia of unknown origin visited inpatient and outpatient facility of department of Medicine and department of Paediatrics, Mymensingh Medical College Hospital (MMCH) in Mymensingh division of Bangladesh. A total of 400 serum samples were screened by Brucella-specific latex agglutination test to determine seropositivity. Seven percent (7.0%) (28/400) serum samples were found to be seropositive for brucellosis by detecting Brucella-specific antibody at a titer ≥1:160. Therefore, Brucella-specific latex agglutination test may be recommended as a screening test for human brucellosis in developing and underdeveloped countries.

Abstract
The leading causes of hepatitis are viral infections, Hepatitis B virus (HBV) and Hepatitis C virus (HCV). Millions of people have been infected with these deadly viral infections worldwide, and in Pakistan, every tenth person is infected with these viruses. Different populations respond with different rates to infectious diseases due to host genomic differences. To evaluate and compare the biochemical parameters in different types of hepatitis (Hepatitis B, C, and Co-infection) and different ethnic groups, a total of 200 pre-screened patients were recruited from District Headquarters Teaching Hospital Dera Ismail Khan and Tank. Blood samples (5ml) were taken from patients and were assayed for biochemical parameters, including four liver function tests (LFTs) and two renal function tests (RFTs). In 200 patients, the mean scores of Alanine transaminase (ALT) were 376±335, 315±265, and 478±519 IU/L in HBV, HCV, and co-infected patients, respectively. Moreover, the mean score of ALT was 31±7.2 IU/l in the normal control group. All other biochemical parameters demonstrated elevated levels in co-infection, HBV, and HCV, respectively, except total proteins. The RFTs showed a threshold or upper normal limit (UNL); nonetheless, when compared to normal control subjects, RFTs parameters were high in infected patients, as compared to normal control. Ethnicity wise comparison of parameters indicated that Pushtoon ethnic group indicated a high degree of severity of HBV infection and co-infection, as compared to Saraiki and Rajpoot ethnic groups, while Saraiki ethnic group showed a higher severity of HCV than both of Pushtoon and Rajpoot. Rajpoot ethnic group was least affected than both Pushtoon and Saraiki ethnic groups. Co-infected patients were more severely affected, as compared to HBV and HCV patients. The ethnicity-wise study provided evidence that different ethnic groups showed different degrees of severity. There may be some genetic background involved in hepatitis B and C viral infection due to which all three ethnic groups showed different degrees of severity. In gender-wise comparisons, male patients were more affected than female patients.

Abstract
Ocular tuberculosis is an extra-pulmonary form of systemic Tuberculosis (TB). It is rarely found concomitant with active pulmonary tuberculosis (PTB). The aim of this prospective observational study was to evaluate the pattern of tubercular uveitis (TBU) in the patients with active PTB who attended in our Uvea clinic at NIO&H from July 2018 to December 2020. Active PTB patients who had uveitis consistent with TBU and TBU patients who were confirmed as active lung lesion were included in the study. Chest X-ray, TST, IGRA (QuantiFERON-TB Gold Test), RT PCR of aqueous fluid for tubercular bacillus, Gene Xpert TB test of sputum were done to confirm the diagnosis of ocular and primary TB. If the induration is 15 mm of TST was considered patient in this study. Among 33 patients of active PTB, 4 had TBU (12.12%). Among 48 patients of TBU, 5 had active PTB (10.41%). 13 eyes of 9 patients were affected. Mean age at presentation was 41.8 years. There were anterior uveitis in 23.00% eyes, posterior uveitis in 69% eyes and panuveitis in 7.00% eyes. Choroidal granuloma was the most common presentation of posterior uveitis (46.00%). There were more than 4 times chance to develop choroidal granuloma in patients with active PTB than extrapulmonary TB (Χ²=4.53, <0.05), TBU patients with choroidal granuloma should be evaluated meticulously for active PTB and active PTB patients should be evaluated routinely by ophthalmologist for the search of TBU.

Abstract
Angiotensin-II is considered as a peptide responsible for the vascular dysfunction and complications in various tissues including liver through inducing free radicle mediated oxidative stress. This study aimed to evaluate the effect of ramipril, an angiotensin-converting enzyme inhibitor (ACE inhibitor), on oxidative stress, inflammation, and fibrosis in the liver of alloxan-induced diabetic rats. In this investigation, rats were divided into four groups (six rats in each group): control, control+ramipril, alloxan, and alloxan+ ramipril. A single dose (90 mg/kg) of alloxan was given intra-peritoneally to induce type two diabetes. After the induction of diabetes, ramipril (10 mg/kg) was administered to each animal for 21 days. An oral glucose tolerance test (OGTT) was performed. All animals were sacrificed at the end of the study. Blood and liver tissues were collected from each animal and stored for further biochemical studies. Liver marker enzymes and oxidative stress parameters were also assayed followed by histological examination in the liver. Alloxan administration in rats showed oral glucose intolerance and increased fasting blood glucose levels. Ramipril (10 mg/kg) treatment in alloxan administered rats improved the OGTT and lowered fasting blood glucose level. This study also revealed the elevation of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) enzymes activities in the alloxan administered rats which were attenuated by ramipril treatment. Oxidative stress parameters such as advanced protein oxidative products (APOP), nitric oxide (NO), and malondialdehyde (MDA) were also increased in alloxan administered rats which were diminished by the treatment of ramipril. Moreover, alloxan administration increased inflammation and fibrosis in the liver, which was further prevented by ramipril treatment. In conclusion, ramipril alleviated oxidative stress and fibrosis in the liver by suppressing oxidative stress. This investigation suggests that ACE inhibitors may be useful for treating diabetic complications and liver injury in alloxan-administered rats.

Abstract
Objective: This study has been designed to determine the effectiveness of heterologous plate¬let-rich plasma (hPRP) against infected wounds in rabbits.
Materials and Methods: Staphylococcus aureus contamination was present in 24 surgical inci¬sions, each 8 mm in diameter. The animals were then divided into two groups as follows: group A, also known as the hPRP group, received topically applied, freshly manufactured hPRP twice weekly, and group B, also known as the control group, only received sterile saline. Evaluations of the histological architecture of wounds, posttherapeutic morphology, morphometry, and in-vitro and in-vivo antimicrobial potentials of hPRP were made.
Results: Rabbits that were given hPRP exhibited quicker rates of wound contraction and shorter healing times. The samples from day 7 in the hPRP group showed less inflammation and more structured fibroblasts than those from the control wounds, according to histological analysis. On day 21 of the histological examination, the hPRP group’s epidermis showed notable thickening. As demonstrated by in-vitro antibacterial activity, undiluted hPRP successfully suppressed S. aureus growth. A serum biochemical analysis showed that hPRP had no harmful effects on the liver or kidneys.
Conclusions: Based on the findings of the histological features, antibacterial properties, and wound morphology, it can be said that hPRP gel holds promise as an alternative to antibiotics for the treatment of wound infections.

Abstract
Abstract
Background
In general, rates of in-hospital cardiac arrest are reportedly 9 to 10 arrests per 1000 admissions, with survival rates of approximately 20–25%. Data regarding clinical characteristics and outcomes in patients with COVID-19 who received in-hospital CPR (cardiopulmonary resuscitation) are limited. This information can help guide end-of-life care conversations between families and health care workers based on real-world experience.
Purpose
To observe the outcomes (survival to discharged alive from the hospital) in critically sick COVID-19 patients who experienced in-hospital cardiac arrest.
Methods
This is a multi-centre institutional review board (IRB) approved retrospective study. The RT-PCR confirmed adult COVID-19 patients consecutively admitted from March 1st to April 30, 2020, were included. Data were extracted manually using the hospital's electronic medical record. The final date of follow-up to monitor clinical outcomes was January 2021.
Results
A total of 721 patients were admitted to the hospital. Of these, only 64 (8.87%) patients had “no CPR” orders.Cardiac arrest occurred in 141 (19.5%) patients. The mean duration of beginning of resuscitation was less than a minute and the mean duration of CPR was 19 minutes. The median age was 65 years; 62.4% were male. The most common co-morbidities were hypertension (66%) and diabetes mellitus (56%). The initial rhythm was non-shockable in 93.7% of patients [asystole in 48.4% and Pulseless Electrical Activity (PEA) in 45.3% of patients]. Only six (4.2%) patients had pulseless ventricular tachycardia and three (2.1%) patients had ventricular fibrillation. A total of eight patients (5.6%) survived and were discharged from the hospital; six (4.25%) had non-shockable and two (0.82%) had shockable initial rhythms. The median age of those who survived was 60 years (Figure 1).
Conclusions
Our study showed that critically sick patients with COVID-19 have a high rate of cardiac arrest and poor outcomes in those who received CPR. A non-shockable initial rhythm indicates that non-cardiac reasons might be playing a major role. These include acute respiratory insufficiency, severe sepsis, or multiorgan failure. These data should inform end-of-life care discussions between providers and patients' families.

Abstract
Brucellosis is a zoonotic disease that is one of the important infectious causes of Pyrexia of Unknown Origin (PUO). The objective of the present study was to determine the seropositivity and molecular detection of human brucellosis among the patients with pyrexia of unknown origin on both risk and non-risk group of individuals in greater Mymensingh. A total of 400 blood samples were randomly collected from pyretic patients started from September 2018 to August 2019. Questionnaires were used to collect data on both risk and non-risk group of individuals. All samples were initially screened for anti-Brucella antibodies using the Brucella-specific latex agglutination test. For accurate investigation, seropositive as well as seronegative serum samples were tested by BCSP31 Brucella genus-specific TaqMan real-time PCR. Overall 32(8%) cases were positive out of 400 samples by Brucella-specific latex agglutination test and/or BCSP31 Brucella genus-specific real-time PCR. Brucella-specific latex agglutination test documented 7% (28/400) positivity for brucellosis. 22(5.5%) samples found Brucella genus-specific real-time PCR positive out of 400 samples. Most real-time PCR positive cases were found from sero-positive samples of risk group population (15/32). Sero-negative but real-time PCR positive cases also found only from risk group population (4/32). There were 10 seropositive cases where real-time PCR was negative. In addition to Brucella-specific latex agglutination test as a screening test, Brucella genus-specific real-time PCR was performed for confirmation and also to avoid unjustified costs, drug toxicity, and masking of other potentially dangerous diseases.

Abstract
Abstract
BACKGROUND
Brain tumours are the leading cause of cancer deaths in the under-40s. Research on end-of-life care, especially in brain tumour patients is rare, yet important to patients and carers. The GlioCova project holds data on all adult brain tumour patients in England diagnosed between 2013 and 2018. Using this linked data set, we performed preliminary analysis on end-of-life care, focusing on treatment close to death and place of death.
MATERIAL AND METHODS
We used data from the English National Cancer Registry and identified all patients with a primary CNS tumour (ICD-10: C70, C71, C72) who were diagnosed between 2013 - 2018. We examined demographics, tumour morphology and grade, primary cause of death, treatment received within the last 3 and 1 month of life, and the location of death. For patients with unclear location of death (‘unknown’, ‘other’, ‘NA’), we looked at their final destination of discharge recorded in their last inpatient admission.
RESULTS
We identified 26,239 brain tumour patients of whom 20,715 had died. 41.7% were female and median age was 68 (IQR=19). Most patients had a malignant neoplasm of brain (98.6%), followed by meninges (0.7%) and spinal cord, cranial nerves and other parts of central nervous system (0.7%). The most common primary cause of death was malignant neoplasm (70%). Of the 10,021(48.4%) patients who received radiotherapy at any time between diagnosis and death, 1,341 (6.5%) received it within the last three months of life and 254 (1.3%) received it within the last month of life. Of the 5,957 (28.8%) patients who received chemotherapy, 1,358 (6.6%) started a chemotherapy regimen 3 months and 200 (0.97%) 1 month before death. 36.0% of all patients died at home, 23.8% at hospital, 14.7% in a hospice and 8.8% in a nursing home. For 16.7% of patients with an unclear location of death, the most common destination of discharge during their last hospital admission was usual place of residence (54.5%), non-NHS run Care Home (13.9%), NHS run Care Home (11.2%).
CONCLUSION
To the best of our knowledge, this is the first national analysis of end-of-life care in brain tumour patients. Active treatment towards the end of life and in a hospital deaths appear lower in brain tumour patients than in studies of other cancer groups.

Abstract
BACKGROUND Permanent chemotherapy-induced alopecia (pCIA), for which preventive interventions remain limited, can manifest with scarring. While the underlying pathomechanisms of pCIA are unclear, depletion of epithelial hair follicle (HF) stem cells (eHFSCs) is likely to play a role. OBJECTIVES To explore the hypothesis that eHFSCs undergo pathological epithelial-mesenchymal transition (EMT) besides apoptosis in pCIA, thus explaining the scarring phenotype. Furthermore, we tested whether a PPARγ modulator can prevent pCIA-associated pathomechanisms. METHODS Organ-cultured human scalp HFs were treated with the cyclophosphamide metabolite, 4-hydroperoxycyclophosphamide (4-HC). Additionally, HFs were pre-treated with the agnostic PPARγ modulator, N-Acetyl-GED-0507-34-Levo (NAGED), which we had previously shown to promote K15 expression and antagonize EMT in eHFSCs. RESULTS In accordance with anticipated hair bulb cytotoxicity, dystrophy and catagen induction, 4-HC promoted apoptosis along with increased p53 expression, DNA damage and pathological EMT in keratin 15+ (K15) bulge eHFSCs, as evidenced by decreased E-cadherin expression and the appearance of fibronectin- and vimentin-positive cells in the bulge. Pre-treatment with NAGED protected from 4-HC-induced hair bulb cytotoxicity/dystrophy, and halted apoptosis, p53 up-regulation, and EMT in the bulge, thereby significantly preventing the depletion of K15+ human eHFSCs ex vivo. CONCLUSIONS A cyclophosphamide metabolite alone suffices to damage and deplete human scalp eHFSCs by promoting apoptosis, DNA damage, and EMT ex vivo. Therefore, pCIA-therapeutic strategies need to target these pathological processes. Our data introduce the stimulation of PPARγ signaling as a novel intervention strategy for the prevention of pCIA, given the ability of NAGED to prevent chemotherapy-induced eHFSCs damage ex vivo.

Abstract
Carcinogenesis is a complex multi-stage process associated with abnormal oncogenic signals in various signaling pathways. HNSCC (Head and neck squamous cell carcinoma) includes the majority of head and neck cancers (HNC). Also, HNSCC indicates a tumors heterogeneous group that derives from the squamous epithelium of the oropharynx, hypopharynx, oral cavity, and larynx. The main cancer management approach contains chemotherapy, radiation, and surgery separately or in combination. Each therapeutic approach has a limitation that influences cancer therapy procedures. Different treatment manners, stimuli-responsive therapeutic methods can improve on-target responses and reduce side effects. Sonodynamic therapy (ST) shows promising potential as an alternative treatment for cancer in the last few years. There is a hypothesis that shows ST using sonosenitizer in combination with low-intensity ultrasound (LIUS) could be useful in all kinds of cancer without focusing on specific target proteins, molecules, and/or genes. This review study discussed the application of ST for the treatment, ST mechanisms, and also, advances in the treatment of HNCs approaches in the recent decades.

Abstract
In this study, an attempt was made to estimate the antioxidant activity of some popular
Bangladeshi legumes by employing DPPH radical scavenging assay, total phenolic
content (TPC), and ferric reducing antioxidant assay (FRAP). The extraction efficiency
and total flavonoid content (TFC) of hyacinth bean (Lablab niger), kidney bean
(Phaseolus vulgaris), black gram (Vigna radiate), mung bean (Vigna mungo), and green
pea (Pisum sativam) by different solvents were also examined. Extraction was done using
80% acetone, ethanol, and methanol as solvent. The maximum and minimum DPPH
scavenging activity was shown by mung bean (27.67±1.53%) and Hyacinth bean
(4.33±1.53%), respectively using ethanol as solvent. The highest and lowest FRAP value
was recorded 89.60±0.80 μg AAE/mL for green pea and 35.11±1.39 μg AAE/mL for
mung bean, respectively with ethanol solvent. For TPC, green pea with ethanol solvent
showed the highest value (1045.92±21.30 mg GAE/100 g), and mung bean with ethanol
solvent exhibited the lowest value (415.92±1.44 mg GAE/100 g). For TFC, black gram
with ethanol solvent exhibited the highest value (342.21±3.05 mg QE/100 g), while mung
bean with acetone solvent exhibited the lowest value (77.38±0.80 mg QE/100 g).

Abstract
A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes to enhance canola productivity. The research was carried out at Agronomy Research Farm, The University of Agriculture Peshawar in winter 2016-2017. The experiment was conducted in randomized complete block factorial design. The study was comprised of three factors including nitrogen (60, 120 and 180 kg ha-1), phosphorous (70, 100 and 130 kg ha-1) and beneficial microbes (with and without BM). A control treatment with no N, P and BM was also kept for comparison. Application of beneficial microbes significantly increased pods plant, seed pod, seed filling duration, 1000 seed weight, biological yield and seed yield as compared to control plots. Nitrogen applied at the rate of 180 kg ha-1 increased pods plant-1, seed pod, seed filling duration, seed weight, biological yield and seed yield. Maximum pods plant-1, seed pod, early seed filling, heavier seed weight, biological yield, seed yield, and harvest index were observed in plots treated with 130 kg.ha-1 phosphorous. As comparison, the combine treated plots have more pods plant-1, seeds pod-1, seed filling duration, heaviest seeds, biological yield, seed yield and harvest index as compared to control plots. It is concluded that application of beneficial microbes with N and P at the rate of 180 kg ha-1 and 130 kg ha-1, respectively, increased yield and its attributes for canola.

Abstract
The effects of two processing methods (boiling and roasting) on physicochemical qualities
of dark red kidney bean (Phaseolus vulgaris) were investigated. Changes in total
polyphenol content (TPC) and antioxidant activity due to processing were also analyzed
by using Folin–Ciocaltue method and 1,1 diphenyl-2-picrylhydrazyl (DPPH) assay,
respectively. Analysis of physicochemical properties exhibited substantial variations
(p<0.05) in the levels of moisture, ash, protein, fat, carbohydrate, gross energy and pH of
raw and processed beans. Meanwhile, there was no considerable difference (p<0.05) in the
fibre content of fresh and processed beans. Investigation of total phenolic content showed
the significant (p<0.05) reduction of phenolic compounds in boiled (5.53±0.74 mg GAE/
g) and roasted (8.15±1.60 mg GAE/g) beans than raw samples (12.55±1.42 mg GAE/g).
DPPH radical scavenging activity was also decreased significantly (p<0.05) in boiled and
roasted samples with IC50 value of 0.0608±0.0765 mg/mL and 0.0523±0.0026 mg/mL,
respectively. In the case of household cooking, keeping boiling water would be advised
for the preservation of minerals, vitamins and phenolic compounds. The roasting process
may be used to develop high-quality health-promoting dark red kidney bean products.

Abstract
BACKGROUND Stromal vascular fraction (SVF), derived enzymatically or mechanically from adipose tissue, contains a heterogenous population of cells and stroma, including multipotent stem cells. The regenerative capacity of SVF may potentially be adapted for a broad range of clinical applications, including the healing of acute cutaneous wounds. OBJECTIVE To evaluate the available literature on the efficacy and safety of autologous adipose-derived stromal vascular fraction (SVF) for the treatment of acute cutaneous wounds in humans. METHODS A systematic review of the literature utilizing MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials was performed to identify published clinical trials of autologous adipose-derived SVF or similar ADSC-containing derivatives for patients with acute cutaneous wounds. This was supplemented by searches for ongoing clinical trials through ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. RESULTS 872 records were initially retrieved. Application of inclusion and exclusion criteria yielded 10 relevant studies: two completed non-randomized controlled trials and eight ongoing clinical trials. Both completed studies reported a statistically significant benefit in percentage re-epithelialization and time to healing for the SVF treatment arms. Safety information for SVF was not provided. Ongoing clinical trials were assessing outcomes such as safety, patient and observer reported scar appearance, wound healing rate, and wound epithelization. CONCLUSION In the context of substantial limitations in the quantity and quality of available evidence, the existing literature suggests that SVF may be a useful treatment for acute cutaneous wounds in humans. More clinical trials with improved outcome measures and safety assessment are needed.

Abstract
Cabbage (Brassica oleracea) is popular winter vegetables cultivated all over Bangladesh
and contains essential nutrients. This study aimed to evaluate the efficacy of pre-blanching
on the preservation of cabbage by drying. In this research work, cabbage was blanched at
80°C, 90°C, and 100°C temperature for 12, 8, and 2 mins, respectively. Then the samples
were dried at 60°C maintaining 60% relative humidity. The moisture and ash content of
untreated and treated dried samples was in the range of 16.07±0.04 to 10.80±0.01% and
5.71±0.06 to 3.81±0.02%, respectively. The total phenolic content in cabbage was
74.47±0.63 mg GAE/100g at 100°C blanching temperature for a short time of 2 mins,
which was higher compared to 61.91±0.48 mg GAE/100g at 80°C for 12 mins. It was
observed that the antioxidant activity and two water-soluble vitamins-ascorbic acid and
beta carotene decreased in pre-blanched dried samples in contrast with fresh ones.
Blanching at higher water temperature and a short period was found useful for the
retention of total phenolic content and greenness of cabbage. Blanching pre-treatments
were also found to have better color retention capacity than untreated dried cabbage. A
proper combination of drying time and temperature, along with the incorporation of
blanching pretreatment, might be useful to preserve cabbage for a long time.

Abstract
BACKGROUND The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials. OBJECTIVES To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC. METHODS One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders. After consolidation of this long list, 55 candidate outcomes were rated by 19 physician and 10 patient stakeholders, in two rounds of Delphi exercises. Outcomes scored 'critically important' (score of 7, 8 or 9) by ≥ 70% of patients and ≥ 70% of physicians were provisionally included. At the consensus meeting, after discussion and voting of 44 international experts and patients, the provisional list was reduced to a final core set, for which consensus was achieved among all meeting participants. RESULTS A core set of seven outcomes was finalized at the consensus meeting: (i) serious or persistent adverse events, (ii) patient-reported quality of life, (iii) complete response, (iv) partial response, (v) recurrence-free survival, (vi) progression-free survival and (vii) disease-specific survival. CONCLUSIONS In order to increase the comparability of results across trials and to reduce selective reporting bias, cSCC researchers should consider reporting these core outcomes. Further work needs to be performed to identify the measures that should be reported for each of these outcomes.

Abstract
This survey presents a review of state-of-the-art deep neural network architectures, algorithms, and systems in vision and speech applications. Recent advances in deep artificial neural network algorithms and architectures have spurred rapid innovation and development of intelligent vision and speech systems. With availability of vast amounts of sensor data and cloud computing for processing and training of deep neural networks, and with increased sophistication in mobile and embedded technology, the next-generation intelligent systems are poised to revolutionize personal and commercial computing. This survey begins by providing background and evolution of some of the most successful deep learning models for intelligent vision and speech systems to date. An overview of large-scale industrial research and development efforts is provided to emphasize future trends and prospects of intelligent vision and speech systems. Robust and efficient intelligent systems demand low-latency and high fidelity in resource-constrained hardware platforms such as mobile devices, robots, and automobiles. Therefore, this survey also provides a summary of key challenges and recent successes in running deep neural networks on hardware-restricted platforms, i.e. within limited memory, battery life, and processing capabilities. Finally, emerging applications of vision and speech across disciplines such as affective computing, intelligent transportation, and precision medicine are discussed. To our knowledge, this paper provides one of the most comprehensive surveys on the latest developments in intelligent vision and speech applications from the perspectives of both software and hardware systems. Many of these emerging technologies using deep neural networks show tremendous promise to revolutionize research and development for future vision and speech systems.

Abstract
This study describes the molecular detection of human brucellosis among patients with pyrexia of unknown origin. It was a cross-sectional descriptive study and was carried out in the Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Non-probability purposive type of sampling technique was used. Blood samples were collected from 400 pyretic patients from September 2018 to August 2019. BCSP31 Brucella genus-specific TaqMan real-time PCR and SYBR Green real-time PCR were undertaken for molecular detection. Out of 400 samples, 22 (5.5%) samples found BCSP31 Brucella genus-specific real-time PCR positive. The study revealed that a considerable number of brucellosis is present in rural areas among risk as well as non-risk group study population having definite male predominancy, most prone to develop among >40-80 years age group. Brucella genus and species-specific real-time PCR might be performed for confirmation and also to avoid unjustified costs, drug toxicity, and un-masking of other potentially dangerous diseases.

Abstract
BACKGROUND Given that unwanted hair growth (hirsutism, hypertrichosis) can cause major psychological distress, new pharmacological treatment strategies with safe and effective hair growth inhibitors that do not destroy the hair follicle (HF) and its stem cells need to be developed. OBJECTIVES To establish if osteopontin-derived fragments may modulate human hair growth given that human HFs express the multifunctional, immunomodulatory glycoprotein, osteopontin. METHODS Our hypothesis was tested ex vivo and in vivo by using a newly generated, toxicologically well-characterized, modified osteopontin-derived peptide (FOL-005), which binds to the HF. RESULTS In organ-cultured human HFs and scalp skin, and in human scalp skin xenotransplants onto SCID mice, FOL-005 treatment (60 nmol L-1 to 3 μmol L-1 ) significantly promoted premature catagen development without reducing the number of keratin 15-positive HF stem cells or showing signs of drug toxicity. Genome-wide DNA microarray, quantitative reverse-transcriptase polymerase chain reaction and immunohistochemistry revealed decreased expression of the hair growth promoter, fibroblast growth factor-7 (FGF7) by FOL-005, while cotreatment of HFs with recombinant FGF7 partially abrogated FOL-005-induced catagen promotion. CONCLUSIONS With caveats in mind, our study identifies this osteopontin-derived peptide as an effective, novel inhibitory principle for human hair growth ex vivo and in vivo, which deserves systematic clinical testing in hirsutism and hypertrichosis. What's already known about this topic? The treatment of unwanted hair growth (hypertrichosis, hirsutism) lacks pharmacological intervention, with only few and often unsatisfactory treatments available. Osteopontin is prominently expressed in human HFs and has been reported to be elevated during catagen in the murine hair cycle. What does this study add? We tested the effects on hair growth of a novel, osteopontin-derived fragment (FOL-005) ex vivo and in vivo. In human hair follicles, high-dose FOL-005 significantly reduces hair growth both ex vivo and in vivo. What is the translational message? High-dose FOL-005 may provide a new therapeutic opportunity as a treatment for unwanted hair growth.
