As pregnancy can adversely affect the immune response of vaccination against foot and mouth disease virus (FMDV) due to physiological immunosuppressive milieu, we tested the effect of FMDV vaccination during mid-gestation on the antibody response. Pregnant and non-pregnant cows of crossbred and indigenous breed (n = 28/group) were vaccinated with inactivated FMD vaccine covering O, A, and Asia1 serotypes and the sera were harvested at weekly interval till day 42 post-vaccination. Virus neutralization test (VNT) was done and the analysis of log VN antibody titer by mixed model ANOVA indicated that pregnancy did not significantly affect the log VN titer for FMDV serotype O and Asia1.

Vulvar carcinoma is a relatively rare malignancy and there is a paucity of data, especially from India and other developing countries regarding the prognostic factors impacting recurrence and survival. A retrospective observational study was conducted in the Department of Gynecologic Oncology at a tertiary care, regional cancer institute, including all patients with carcinoma vulva who underwent surgery between 2009 and 2018. Demographic profile, surgical-pathological information, details of neo-adjuvant chemotherapy, adjuvant radiation and chemotherapy, and peri-operative complications were analyzed.

Extensive investigations were made and empirical relations were proposed for the thermal conductivity of mono-nanofluids. The effect of concentration, diameter, and thermal properties of participating nanoparticles is missing in the majority of existing thermal conductivity models. An attempt is made to propose a model that considers the influence of such missing parameters on the thermal conductivity of hybrid nanofluids.

is a group of microbes known for antibiotic production and has contributed to more than 70% of present commercially available antibiotics. These antibiotics are important in the management, protection, and treatment of chronic illnesses. In the present study, the isolated strain from mangrove soil in Mangalore, India (GenBank accession number: MW785875) was subjected for differential cultural characterization, phenotype involving brown pigmentation, filamentous mycelia, and ash-colored spore production was observed using field emission scanning electron microscopy (FESEM) analysis revealing filamentous mycelia possessing a straight spore chain.

Till now Mg-based alloys have attracted much attention due to the high storage capacity of hydrogen. An effort was made to evaluate the apparent activation energy and electrochemical behavior of transition metals such as scandium (Sc), zirconium (Zr), and niobium (Nb) alloyed with Mg-Ti. MgTi, MgTiSc, MgTiZr, and MgTiNb alloy powders were synthesized using high-energy ball milling.

The aim of this study was to evaluate the clinico-pathological behaviour and treatment patterns of low-grade serous carcinomas (LGSC) of ovary treated at a regional cancer centre. A retrospective analysis was done for the histopathology-proven cases of low-grade serous ovarian carcinoma, treated at a tertiary cancer institute between January, 2010, and September, 2019. There were 28 patients identified from the medical records with low-grade serous ovarian carcinoma.

Magnesium matrix composites are extensively used in automotive and structural applications due to their low density, high strength, and wear-resistant properties. To reach the scope of industry needs, research is carried out regarding enhancing the mechanical and tribological behavior of the magnesium composites by reinforcing the nano-sized reinforcements. In the present work, research has been carried out to enhance the properties of the magnesium AZ91D hybrid composite by reinforcing carbon fibers (CFs) and multi-walled carbon nanotubes (MWCNTs) with varying weight percentages (AZ91D + 0.

Two-dimensional nanostructures have gained tremendous interest in the field of biomedical applications and cancer activity in particular. Although sulfur is known for its wide range of biological activities, its potentiality in two-dimensional forms as an antitumor agent is hitherto unexplored. To address the current deficient knowledge on nano-sulfur as an antitumor agent, we report the synthesis of nano-sulfur sheets/particles and their cytotoxic, apoptotic activity against human carcinoma cell lines.

Introduction: Human papilloma virus (HPV) has been associated with oral squamous cell carcinoma (OSCC) as a potential carcinogen. There are several types of HPV, of which type 16 has been strongly implicated in carcinogenesis. HPV16 in saliva can potentially facilitate early detection of subclinical cases that may warrant further diagnosis, monitoring and intervention.

Aim: Studies on the changes in the presentation and management of acute myocardial infarction (AMI) during the COVID-19 pandemic from low- and middle-income countries are limited. We sought to determine the changes in the number of admissions, management practices, and outcomes of AMI during the pandemic period in India.

Methods & Results: In this two-timepoint cross-sectional study involving 187 hospitals across India, patients admitted with AMI between 15th March to 15th June in 2020 were compared with those admitted during the corresponding period of 2019.
