A Century-Old Threat: Disseminated Tuberculosis in a Healthy Host - Case Report.

Disseminated tuberculosis (dTB) is usually rare in immunocompetent individuals. We report a case of dTB presented with constitutional symptoms and extensive lymphadenopathy with bilateral lung parenchymal airspace opacities. Histopathological and molecular methods confirmed the etiological agent - Mycobacterium tuberculosis.

Attrition in serum anti-DENV antibodies correlates with high anti-SARS-CoV-2 IgG levels and low DENV positivity in mosquito vectors-Findings from a state-wide cluster-randomized community-based study in Tamil Nadu, India.

The decline in dengue incidence and/or prevalence during the COVID-19 pandemic (2020-22) appears to be attributed to reduced treatment-seeking rates, under-reporting, misdiagnosis, disrupted health services and reduced exposure to mosquito vectors due to prevailing lockdowns. There is limited scientific data on dengue virus (DENV) disease during the COVID-19 pandemic. Here, we conducted a community-based, cross-sectional, cluster-randomized survey to assess anti-DENV and anti-SARS-CoV-2 seroprevalence, and also estimated the spatial distribution of DENV-positive aedine mosquito vectors during the COVID-19 pandemic across all the 38 districts of Tamil Nadu, India.

Serosurveillance of dengue infection and correlation with mosquito pools for dengue virus positivity during the COVID-19 pandemic in Tamil Nadu, India - A state-wide cross-sectional cluster randomized community-based study.

Background: Dengue is a vector-borne viral disease impacting millions across the globe. Nevertheless, akin to many other diseases, reports indicated a decline in dengue incidence and seroprevalence during the COVID-19 pandemic (2020-22). This presumably could be attributed to reduced treatment-seeking rates, under-reporting, misdiagnosis, disrupted health services and reduced exposure to vectors due to lockdowns.

Single nucleotide polymorphisms of Interleukin - 4, Interleukin-18, FCRL3 and sPLA2IIa genes and their association in pathogenesis of endometriosis.

Background: Endometriosis is a complex gynaecological disorder that contributes to infertility, dysmenorrhea, dyspareunia, and other chronic issues. It is a multifactorial disease involving genetic, hormonal, immunological and environmental components. Endometriosis's pathogenesis remains unclear.

Central nervous system tubercular abscess masquerading as intracranial space-occupying lesion.

This is a case report of patient suffering from multiple central nervous system tuberculoma which progressed to tubercular abscess. Patient developed signs and symptoms of mass effect and compression. Computed tomography of brain and magnetic resonance spectroscopy confirmed the diagnosis.

A rare chromosomal polymorphism in a Kangayam bull () of south India.

A chromosomal polymorphism was detected on karyological screening of Kangayam breeding sires prior to subjecting them for frozen semen collection. One bull possessed the chromosomal complement 2n = 60, consisting of 58 acrocentric autosomes, one large sub-metacentric X-chromosome, and one small acrocentric Y-chromosome with a small visible p-arm, which was further confirmed using CBG- and GTG-banding. This polymorphism was attributed to a heterochromatin variation of the acrocentric Y-chromosome routine in the Linnaeus, 1758 cattle.

Genetic and non-genetic factors affecting semen production and quality characteristics of Gir cattle breed under semi-arid climate.

Aim: This study aims to evaluate genetic and non-genetic factors influencing semen production potential of Gir bulls.

Materials And Methods: Data on semen quantity (n=6911) and quality (n=466) available from January 2011 to December 2018 at BAIF's frozen semen station, Jind, Haryana, India, were utilized for the study. Factors, namely, season of collection, age at collection, and bull (random effect) were studied for their effect on quantitative and qualitative semen traits.

Ascertaining the paternal lineage in crossbred calves.

Karyotyping is one among the culling parameter used for taking up culling decisions. Cytogenetic screening of breeding bulls has been recommended to screen for chromosomal abnormalities before semen production in artificial insemination. The chromosomal analysis of a Holstein Friesian crossbred bull revealed the presence of acrocentric Y-chromosome, which was further confirmed by CBG banding.

Polymorphic Regions in Fc Gamma Receptor and Tumor Necrosis Factor-α Genes and Susceptibility to Chronic Periodontitis in a Cohort From South India.

Background: Polymorphisms in the immunoglobulin G Fc receptor II (FcGR) and tumor necrosis factor-α (TNFA) genes are known to influence pathogenesis and severity of several inflammatory conditions. Association of FcGR and TNFA gene polymorphisms with chronic periodontitis (CP) susceptibility has been found to be diverse among different ethnic populations. Objectives of the present study are to determine association of functional single nucleotide polymorphisms (SNPs) in FcGR and TNF-α genes with CP susceptibility in a cohort from South India.

Molecular docking studies shows tivozanib and lapatinib as potential inhibitors of EML4-ALK translocation mediated fusion protein in non small cell lung cancer.

Identification of activating mutations in non-small cell lung cancers (NSCLC) has been a focus in recent years. This led to successful evidence of using tyrosine kinase inhibitors (TKIs) over the standard platinum doublet based chemotherapy as the first line treatment in the metastatic setting.The rearrangements of fusion protein EML4-ALK in NSCLC lead to the use of crizotinib for this class of tumors.

Association between interleukin-1 gene polymorphism and severity of chronic periodontitis in a south Indian population group.

Background: Periodontitis is a bacterial disease modified by multiple factors. Interleukin-1 (IL-1) is a key regulator of the host response and a major modulator of extracellular matrix catabolism and bone resorption. It has been reported that variations in IL-1 gene are associated with increased susceptibility to periodontitis.

Sublethal effect of copper toxicity against histopathological changes in the spiny lobster, Panulirus homarus (Linnaeus, 1758).

The tissue damage induced by various organic pollutants in aquatic animals is well documented, but there is a dearth of information relating to the histological alterations induced by copper in the spiny lobster. In the present study, intermoult juveniles of the spiny lobster Panulirus homarus (average weight 150-200 g) were exposed to two sublethal concentrations of the copper (9.55 and 19.

Anthropogenic nexus on organochlorine pesticide pollution: a case study with Tamiraparani river basin, South India.

The levels of 17 organochlorine pesticides residues (OCPs) in surface water and sediments from Tamiraparani river basin, South India were investigated to evaluate their potential pollution and risk impacts. A total of 96 surface water and sediment samples at 12 sampling stations were collected along the river in four seasons during 2008-2009. The ΣOCP concentrations in surface water and sediments were in the range of 0.

Effect of copper on morphology, weight, and chromosomal aberrations in the spiny lobster, Panulirus homarus (Linnaeus, 1758).

Spiny lobster Panulirus homarus which had been exposed to cupric ion at 9.55 and 19.1 μg/l for 28 days was examined for sub-lethal effects including morphology, wet weight, and induced genotoxic effect on the chromosome.

Modification of cyclophosphamide-induced clastogenesis and apoptosis in rats by alpha-lipoic acid.

The aim of the present study was to investigate the protective efficacy of alpha-lipoic acid (LA) on the cyclophosphamide (CP)-induced chromosomal aberrations (CA) and apoptosis in the bone marrow of rats. Male Wistar rats of 140+/-20 g were categorized into eight groups. Five groups were administered CP (40 mg/kg body weight, intraperitoneally) to induce toxicity; four of these groups received a single intraperitoneal injection of LA at a dose of either 100 or 200 mg/kg body weight, and either 30 or 60 min prior to CP administration.

Salubrious effects of lipoic acid against adriamycin-induced clastogenesis and apoptosis in Wistar rat bone marrow cells.

Adriamycin (ADR), an anthracycline antibiotic, which is widely used as an antineoplastic drug in the treatment of various solid tumors, has been shown to induce genotoxicity in erythropoietic system. The aim of the present study was to investigate the protective efficacy of DL-alpha-lipoic acid (LA) on ADR-induced clastogenicity and apoptosis in the bone marrow of rats. The animals were randomly divided into eight groups consisting of six rats each.
