Mishra AK, Santos R, Hall-Spencer JM. Elevated trace elements in sediments and seagrasses at CO 2 seeps. MARINE ENVIRONMENTAL RESEARCH 2020; 153:104810. [PMID: 31733909 DOI: 10.1016/j.marenvres.2019.104810] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 09/29/2019] [Accepted: 10/04/2019] [Indexed: 06/10/2023]
Abstract
Seagrasses often occur around shallow marine CO2 seeps, allowing assessment of trace metal accumulation. Here, we measured Cd, Cu, Hg, Ni, Pb and Zn levels at six CO2 seeps and six reference sites in the Mediterranean. Some seep sediments had elevated metal concentrations; an extreme example was Cd which was 43x more concentrated at a seep site than its corresponding reference site. Three seeps had metal levels that were predicted to adversely affect marine biota, namely Vulcano (for Hg), Ischia (for Cu) and Paleochori (for Cd and Ni). There were higher-than-sediment levels of Zn and Ni in Posidonia oceanica and of Zn in Cymodocea nodosa, particularly in roots. High levels of Cu were found in Ischia seep sediments, yet seagrass was abundant there, and the plants contained low levels of Cu. Differences in bioavailability and toxicity of trace elements helps explain why seagrasses can be abundant at some CO2 seeps but not at others.

Volatile organic compound measurements point to fog-induced biomass burning feedback to air quality in the megacity of Delhi. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 689:295-304. [PMID: 31276997 DOI: 10.1016/j.scitotenv.2019.06.438] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Revised: 06/25/2019] [Accepted: 06/26/2019] [Indexed: 06/09/2023]
Abstract
We report the first ambient measurements of thirteen VOCs for investigations of emissions and air quality during fog and non-fog wintertime conditions at a tower site (28.57° N, 77.11° E, 220 m amsl) in the megacity of Delhi. Measurements of acetonitrile (biomass burning (BB) tracer), isoprene (biogenic emission tracer in daytime), toluene (a traffic exhaust tracer) and benzene (emitted from BB and traffic), together with soluble and reactive oxygenated VOCs such as methanol, acetone and acetaldehyde were performed during the winters of 2015-16 and 2016-17, using proton transfer reaction mass spectrometry. Remarkably, ambient VOC composition changes during fog were not governed by solubility. Acetaldehyde, toluene, sum of C8-aromatics (e.g. xylenes), sum of C9-aromatics (e.g. trimethyl benzenes) decreased by ≥30% (>95% confidence interval), whereas acetonitrile and benzene showed significant increases by 20% (>70% confidence interval), even after accounting for boundary layer dilution. During fog, the lower temperatures appeared to induce an emissions feedback from enhanced open BB within Delhi for warming, releasing both gaseous and aerosol pollutants with consequences for fog chemistry, sustenance and intensity. The potential feedback is important to consider for improving current emission parametrizations in models used for predicting air quality and fog in such atmospheric environments.

Abstract
There is an exponential growth in the field of biomedical literature over the years. Although numerous articles are published every year, few of them present important conceptual advances in that particular field and are found to be influential in the evolution of the field. The number of citations a publication receives can be used as a proxy marker of its impact on the field. Hence we aimed to analyze the top cited articles (n = 100) on obsessive compulsive disorder (OCD) as of July 2018. Google scholar database was searched using a freely available software, Publish or Perish. Information related to number of citations, publication title, publication year, name of the journal, country of origin, author details, institution of origin, article type, and article design. The original research articles were further classified into descriptive/epidemiology, mechanism, management, scale/measurement, imaging and medical psychiatry. The citation classics suggest that clinical trials/management, epidemiology and neuroimaging were the most researched areas in the OCD research. These citation classics provide an important insight into the historical developments, like the role of serotonin and caudate in OCD. This approach of citation analysis provides an opportunity to retrieve the classic articles on OCD, and describes the trends in OCD research.

Abstract
Background Anxiety disorders are the most frequent mental disorders encountered in childhood and adolescent years. The number of epidemiological studies done in this area within India is limited. Objectives We determined the prevalence of anxiety disorders among adolescents in a rural community of Ballabgarh block, district Faridabad, Haryana. Secondarily, we also assessed sociodemographic and other factors associated with anxiety disorders among adolescents. Materials and Methods This community-based cross-sectional study was conducted among 729 adolescents (10-19 years). Screen for Child Anxiety-Related Emotional Disorders tool was used for assessing prevalence and type of anxiety disorders. Sociodemographic and personal factors were included in the logistic regression multivariable model to establish associations. Adjusted odds ratios (AOR) along with 95% confidence intervals (CI) are computed. Results The prevalence of anxiety disorders among adolescents was (22.7%; 95% CI: 19.7-26.0). Girls (27.6%) had higher prevalence than boys (18.3%) (P < 0.01). Social anxiety disorder (14.3%; 95% CI: 11.7-16.9) was the most common form of anxiety disorder. Female sex (AOR 1.8; 95% CI 1.2-2.6; P < 0.01), lower-middle socioeconomic status (AOR 1.96; 95% CI 1.2-3.1; P < 0.01), and presence of stressful event within the past 1-year (AOR 2.48; 95% CI: 1.12-5.06; P = 0.01) were found to be associated with the presence of anxiety disorders. Conclusions Anxiety disorders are common among adolescents in rural settings of India. Tackling them will require appropriate health systems response. Adequate interventions should be incorporated at primary care level to address the mental health concerns of adolescents.

Abstract
Introduction: Well-structured instructions for authors in journals help researchers in reporting unbiased results, which subsequently facilitates the review process. There have been reports of systematic evaluations of instructions for authors from journals in various medical specialties. However, precise information on the nature and extent of these instructions for authors in addiction science is lacking. Hence, this study systematically evaluated the instructions for authors for journals in addiction science. Methods: A total of 1139 journal titles were retrieved across multiple databases. Finally, 88 exclusive titles fulfilling the eligibility criteria were considered in this study. The four domains evaluated were journal characteristics, reporting, statistical reporting, and ethical requirements. Results: More than half of the journals were published by academic institutions or professional societies. Less than one-fourth of the journals endorsed adherence to various reporting guidelines and endorsed the Consolidated Statements on Randomized Controlled Trials guidelines to the maximum level (14.8%). Approximately, half (48.9%) of the journals had a separate section on "statistical analysis." The various parameters of statistical reporting were suboptimally endorsed. Conclusion/Importance: The instructions for authors in addiction science journals provide insufficient information in various domains. There is an urgent need to improve the author instructions segment of addiction science journals so that the process of research dissemination can occur more effectively. A higher rate of endorsement of various reporting guidelines and statistical reporting may help to minimize reporting bias as well as prevent unnecessary delays in the publication of important research findings.

Abstract
Setting: Four Tuberculosis (TB) Units in the Union Territory of Puducherry in India. Objectives: To identify factors associated with unfavourable outcomes among retreatment TB cases in Puducherry. Design: The study had a mixed-methods design in which routinely reported TB data from retreatment TB cases registered during 2014 and 2015 were used for the quantitative part; the qualitative phase comprised interviews and focus group discussions with health care providers. Results: Among the 392 retreatment cases, 297 (75.8%) had favourable outcomes. Outcome for previous treatment such as loss to follow-up (LTFU) (adjusted relative risk [aRR] 1.6, 95%CI 1.1-2.4, P = 0.001), treatment failure (aRR 1.7, 95%CI 1.04-2.8, P = 0.03) and pre-treatment weight <40 kg (aRR 1.8, 95%CI 1.3-2.5, P = 0.001) had increased risk for unfavourable outcomes. Health care providers reported that alcoholism, lack of family support, job-related issues and lack of access to trained staff for injections were some of the reasons for unfavourable outcomes. Providing incentives, nutritional supplements and early retrieval of the LTFU cases were some of the suggestions to reduce unfavourable outcomes. Conclusion: Outcome of previous treatment and low pre-treatment weight of the patient affected retreatment outcomes. Health professionals and workers highlighted social and health system-related factors. Commitment at all levels on the part of health care providers and addressing their concerns can improve retreatment outcomes.

Abstract
Crossbreds of low-producing indigenous cattle and high-producing exotic dairy bulls (Holstein Friesian and Jersey) have contributed in ensuring that India continues to be the world's top milk-producing country. However, subfertility observed in crossbred male progenies has been a major obstacle in exploitation of heterosis due to crossbreeding. There is sufficient scientific evidence in support of genetic and epigenetic regulation of key physiological processes including spermatogenesis. Bovine Vasa Homology (Bvh) is considered a molecular marker for the study of gametogenesis. Significant negative correlation between DNA methylation and gene expression has been reported in cattle-yaks hybrids and their parents. The present study analyzed promoter methylation status and expression profile of Bvh gene in spermatozoa from exotic Holstein Friesian cattle, indigenous Sahiwal cattle and their crossbreds with varying semen motility parameters. The degree of methylation of the Bvh promoter region was significantly higher in poor motility crossbred bulls (13.3%) as compared to good motility crossbreds (5.3%), Sahiwal (3%) and Holstein Friesian bulls (1%) (P < 0.05). Gene expression analysis revealed significantly higher mRNA abundance of Bvh in purebreds (Holstein Friesian and Sahiwal) as compared to crossbred counterparts (P < 0.001). Inverse correlation observed in this study between promoter methylation and gene expression of Bvh gene in spermatozoa from crossbred bulls with poor motility phenotype as compared to purebred parents provides an important insight into understanding the graded fertility of crossbred bulls.

Abstract
Salmonella Abortusequi causes important clinical diseases in horses possibly leading to abortion. In the present investigation, the protective efficacy of both plain and aluminum hydroxide gel adjuvanted phage lysate was evaluated in guinea pig model. Broad host range bacteriophage PIZ-SAE-2, was characterized and used for generation of lysates. Three different lysate batches, produced through separate cycles and characterized, were pooled together for immunization study. Plain and adjuvanted phage lysate preparations elicited both humoral and cellmediated immunity. The adjuvanted lysate at a dose of 50 μl elicited the highest protective efficacy against direct challenge at 28th DPI. Thus, the present study describes a new method of bacterial inactivation for producing a new class of better & safe immunprophylactic agents. This is the first report of producing an inactivated vaccine candidate using a new approach against equine salmonellosis.

Abstract
OBJECTIVES In our ongoing studies to develop ER targeting agents, we screened for dual-acting molecules with a hypothesis that a single molecule can also target both ER positive and negative groups of breast cancer. MATERIALS AND METHODS 1-(2-(4-(Dibenzo[b,f]thiepin-10-yl)phenoxy)ethyl)piperidine (DTPEP) was synthesized and screened in both MCF-7 (ER+ve) and MDA-MB-231 (ER-ve) cells. Assays for analysis of cell cycle, ROS, apoptosis and MMP loss were carried out using flow cytometry. Its target was investigated using western blot, transactivation assay and RT-PCR. In vivo efficacy of DTPEP was validated in LA-7 syngeneic rat mammary tumour model. RESULTS Here, we report identification of dual-acting molecule DTPEP that downregualtes PI3K/Akt and PKCα expression, induces ROS and ROS-dependent apoptosis, loss of mitochondrial membrane potential, induces expression of caspase indicative of both intrinsic and extrinsic apoptosis in MCF-7 and MDA-MB-231 cells. In MCF-7 cells, DTPEP downregulates ERα expression and activation. In MDA-MB-231 cells, primary cellular target of DTPEP is not clearly known, but it downregualtes PI3K/Akt and PKCα expression. In vivo study showed regression of LA-7 syngeneic mammary tumour in SD rat. CONCLUSIONS We identified a new dual-acting anti-breast cancer molecules as a proof of concept which is capable of targeting both ER-positive and ER-negative breast cancer.

Abstract
Background Approximately 5% of all fractures consists of proximal humeral fractures. In the elderly population, most of these fractures are related to osteoporosis. Internal fixation has led to unpredictable results, especially in patients with osteopenic bone and those with comminuted fractures. Objective To evaluate functional outcome and complications following proximal humerus fracture fixation using locking plate. Method This prospective observational study was conducted at Nepal Medical College and Teaching Hospital from February 2014 to June 2015. We reviewed 35 patients with proximal humerus fractures, who underwent open reduction and internal fixation with locking plate.Functional outcome was evaluated according to the ConstantMurley shoulder assessment. Result Fracture union was achieved in all cases with the mean time to union being 14.6 weeks (11-24 weeks). At the final follow up the mean constant murley score was 73.6 (48-94). There was total 8(22.85%) cases who developed complication. Conclusion Internal fixation with the locking plate for proximal humerus fractures provides stable construct with better functional outcome as it allows early shoulder mobilization.

Abstract
This work examined window/door opening as means of bedroom ventilation and the consequent effect upon occupants' sleep, using data from 17 healthy volunteers. Bedroom CO2 level, temperature, and relative humidity were measured over 5 days, for two cases: open window or door (internal, bedroom door), and closed window and door. Participant filled questionnaires and sleep diary provided subjective measure of sleep quality. Actigraphy objectively monitored the participants during sleep. Additionally, a FlexSensor, placed under pillows of participants, detected movement during sleep. Average CO2 level for the Open conditions was 717 ppm (SD = 197 ppm) and for Closed conditions was 1150 ppm (SD = 463 ppm). Absolute humidity levels were similar for both conditions, while Open conditions were slightly cooler (mean = 19.7°C, SD = 1.8°C) than Closed (mean = 20.1°C, SD = 1.5°C). Results showed significant correlations (P < .001) between actigraphy data and questionnaire responses for: sleep latency (r = .45), sleep length (r = .87), and number of awakenings (r = .28). Of all analyzed sleep parameters, questionnaire-based depth of sleep (P = .002) and actigraphy-based sleep phase (P = .003) were significantly different between Open and Closed conditions.

Abstract
BACKGROUND AND PURPOSE Dengue is a common arboviral disease, which uncommonly involves the brain. There has been a recent surge in dengue cases and dengue-related deaths in tropical countries. The aim of this study was to describe brain imaging findings in patients with dengue infection having neurologic symptoms. MATERIALS AND METHODS Thirty-five patients with positive serology for dengue with CNS symptoms undergoing imaging of the brain were included in the study. Clinical, laboratory, and imaging parameters were assessed and correlated to poor outcome. RESULTS A Glasgow Coma Scale score of ≤12 at presentation, clinical classification of severe-type dengue, and the presence of acute renal failure were associated with poor outcome. Imaging parameters associated with poor outcome were involvement of the thalami and cerebellar peduncles and the presence of diffusion restriction and hemorrhagic foci in the brain parenchyma. CONCLUSIONS Although not specific, dengue infection has imaging findings that can be used to narrow down the differential list and help in prognostication.

Abstract
Aim: Assessment of the status of subclinical mastitis (SCM) in Jamunapari and Barbari goats in Indian organized farms, the involvement of bacterial pathogens and their sensitivity to antibiotics. Materials and Methods: A total of 181 composite milk samples were aseptically collected from the apparently healthy Barbari (n=95) and Jamunapari (n=86) goats. The California mastitis test (CMT) and somatic cell count (SCC) were used to diagnose SCM. The milk samples with CMT scores of 0 and +1 were considered as negative, while the samples with the score of +2 or +3 were taken as positive, and further, the positive samples were used for the bacteriological examination. An antibiotic sensitivity test was performed by disk diffusion method using seven commercially available antibiotic discs. Results: All the samples having CMT score of +2 or +3 demonstrated SCC more than 1 million. Overall, the prevalence of SCM in the goats was assessed as 19.89% (36/181). The prevalence of SCM in Barbari and Jamunapari goats was found as 24.21% (23/95) and 15.12% (13/86), respectively. Out of 11 isolates of Staphylococci, 9 isolates were identified as coagulase-negative Staphylococci (CNS), whereas 2 isolates were found as Staphylococcus aureus. The identified bacterial isolates (n=30) did not show antibiotic resistance. Conclusion: The current investigation showed the considerable prevalence of SCM among Jamunapari and Barbari goats which may have a negative impact on quantity and quality of the milk. CNS was found as the most prevalent cause of SCM in the goats. Negligible antibiotic resistance was found among the identified udder pathogens.

Abstract
INTRODUCTION Erectile dysfunction (ED) is a common complication of diabetes mellitus. ED, like other sexual disorders, is often under-reported and under-diagnosed, as talking about sex is considered a taboo in our society. METHODOLOGY All the male patients with diabetes mellitus (with or without active complaints of ED) attending Medicine or Psychiatry OPD of the institute during the study period were enrolled in the study. They were investigated for their body-mass index (BMI), blood sugar and lipid profile; and were assessed on HAM-D, General Health Questionnaire-30, IIEF, sex myth checklist and QOL Instrument for Indian Diabetes Patients (QOLID). RESULT AND DISCUSSION In the present study, a total of 138 diabetic patients were assessed, and those with severe ED were found to have poor glycemic control, worse lipid profile, higher body mass index, later age of onset, and longer duration of untreated diabetes as compared to non-ED patients. ED patients also scored higher on depression rating scale, had poorer general health and quality of life (QOL). Early attention to ED in diabetic patients can improve general health and QOL of the sufferers. CONCLUSION DM patients with poor glycemic control and advanced age have a higher propensity of developing severe ED, which further deteriorates the already compromised health & QOL.

Abstract
AIM The aim of the present study was to investigate the molecular etiopathology of occurrence of reproductive diseases in female goats. Reproductive diseases in goats account for major economic losses to goat farmers in terms of valuable loss of offspring and animal productivity. MATERIALS AND METHODS A total of 660 female genitalia were examined for pathological conditions (macroscopic and microscopic lesions). The etiopathological study was carried out for the presence of pathogenic organisms such as Brucella, Chlamydia, and Campylobacter in the uterus and ovary. Based on the microscopic lesions, suspected samples were subjected to diagnostic polymerase chain reaction (PCR) for various etiological agents employing 16srRNA genus specific primers for Campylobacter and Chlamydophila and OMP31 gene-based PCR for Brucella melitensis and nested PCR using ITS-1 gene primers for Toxoplasma gondii. For Brucella suspected samples, immunohistochemistry (IHC) was also performed. RESULTS In studied female genitalia, 108 (16.30%) showed gross abnormalities with overall 23.32% occurrence of pathological conditions (macroscopic and microscopic lesions). Pathological involvement of the uterus was the highest 68 (62.96%), followed by the ovaries 27 (25%) and other organs. Major uterine condition observed was endometritis (5.60%). In uterine infections, 35 (5.30%) samples were found positive for Campylobacter spp., 12 (1.81%) samples for B. melitensis, and 3 (0.45%) samples were positive for Chlamydophila spp. Among the samples positive for B. melitensis by PCR, 3 were found positive by IHC also. Corynebacterium ovis was detected by PCR using specific primers in a case of hydrosalpinx. It was concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats. CONCLUSION The present study concluded that many pathological lesions in female genitalia of functional significance play a major role in infertility in goats.

Abstract
Urothelial cancer patients are prone to recurrence, and there is no marker to predict which cases become refractory to the immunotherapy given to these patients. Tumour behaviour is decided by the dynamics between the pro- and anti-tumorigenic cytokines. In this study, 27 cytokines were estimated in serum and urine of 72 urothelial cancer patients and 42 healthy volunteer controls. Serum cytokines IL-1RA, IL-4 and RANTES were in significantly higher concentration in serum of patients compared to controls, while IL-2 was significantly less in concentration. Patients were found to have significantly high concentrations of 12 urinary cytokines (IL-2, IL-4, IL-8, IL-10, GM-CSF, IFN-γ, IP-10, MIP-1a, PDGF, MIP-1b, RANTES and VEGF) in comparison to healthy controls. Serum VEGF and urinary IL-1ra, IL-4, IL-10, GM-CSF, IP-10, MIP-1a and MIP-1b concentrations were found significantly higher in concentration in high-grade tumours compared to low-grade tumours. There was no difference in either the serum or urinary cytokines between non-invasive and muscle-invasive cases. Serum IL-1ra, IL-6, IL-10, TNF-α and VEGF and urinary IL-1ra, IL-4, IL-8, IL-10, GM-CSF, IP-10, MIP-1a, PDGF, MIP-1b and VEGF were found to be significantly higher in recurrent patients compared to non-recurrent patients. Of these, high concentrations of urinary IL-1RA, IL-4, IL-10, IP-10, PDGF and VEGF and serum IL-1ra, IL-6, IL-10, VEGF and TNF-α were associated with poor recurrence-free survival. Poor recurrence-free survival was also seen with increasing number of cytokines showing high concentrations. The study shows that the estimation of a combination of these cytokines in minimally or non-invasive samples may act as a prognostic indicator.

Abstract
In this work, the exceptionally improved sensing capability of highly porous three-dimensional (3-D) hybrid ceramic networks toward reducing gases is demonstrated for the first time. The 3-D hybrid ceramic networks are based on doped metal oxides (MexOy and ZnxMe1-xOy, Me = Fe, Cu, Al) and alloyed zinc oxide tetrapods (ZnO-T) forming numerous junctions and heterojunctions. A change in morphology of the samples and formation of different complex microstructures is achieved by mixing the metallic (Fe, Cu, Al) microparticles with ZnO-T grown by the flame transport synthesis (FTS) in different weight ratios (ZnO-T:Me, e.g., 20:1) followed by subsequent thermal annealing in air. The gas sensing studies reveal the possibility to control and change/tune the selectivity of the materials, depending on the elemental content ratio and the type of added metal oxide in the 3-D ZnO-T hybrid networks. While pristine ZnO-T networks showed a good response to H2 gas, a change/tune in selectivity to ethanol vapor with a decrease in optimal operating temperature was observed in the networks hybridized with Fe-oxide and Cu-oxide. In the case of hybridization with ZnAl2O4, an improvement of H2 gas response (to ∼7.5) was reached at lower doping concentrations (20:1), whereas the increase in concentration of ZnAl2O4 (ZnO-T:Al, 10:1), the selectivity changes to methane CH4 gas (response is about 28). Selectivity tuning to different gases is attributed to the catalytic properties of the metal oxides after hybridization, while the gas sensitivity improvement is mainly associated with additional modulation of the electrical resistance by the built-in potential barriers between n-n and n-p heterojunctions, during adsorption and desorption of gaseous species. Density functional theory based calculations provided the mechanistic insights into the interactions between different hybrid networks and gas molecules to support the experimentally observed results. The studied networked materials and sensor structures performances would provide particular advantages in the field of fundamental research, applied physics studies, and industrial and ecological applications.
