Recombinant 3AB3 nonstructural protein-based indirect ELISA for detection of foot-and-mouth disease virus infection-elicited antibodies in goat.

Foot-and-mouth disease (FMD) is one of the most important animal diseases of economic significance globally. It is a highly infectious and contagious disease of cloven-hoofed animals including sheep and goat. For sero-diagnosis of FMD, recombinant antigen-based assays are considered as alternatives to conventional approaches such as the liquid phase blocking ELISA (LPBE).

Complete coding region sequence analyses and antigenic characterization of emerging lineage G-IX of foot- and-mouth disease virus serotype Asia1.

Foot-and-mouth disease Virus (FMDV) serotype Asia1 is prevalent in the Indian subcontinent, with only G-III and G-VIII reported in India until 2020. However, in 2019, a novel genetic group within serotype Asia1, designated as G-IX, emerged in Bangladesh, followed by its detection in India in 2020. This report presents analyses of the complete coding region sequences of the G-IX lineage isolates.

Estimation of foot-and-mouth disease virus sero-prevalence rates using novel computational approach for the susceptible bovine population in India during the period 2008-2021.

Foot-and-mouth disease (FMD) is a severe contagious viral disease of cloven-hoofed animals. In India, a vaccination-based official FMD control programme was started, which got expanded progressively to cover entire country in 2019. The serological tests are used to determine non-structural protein based sero-prevalence rates for properly implementing and assessing the control programme.

Porcine respiratory disease complex (PRDC) in Indian pigs: a slaughterhouse survey.

Porcine Respiratory Disease Complex (PRDC) is an unequivocally leading cause of economic losses to the pig industry. To investigate the pathogens associated with PRDC, a total of 900 lungs with gross lesions and 125 lungs with no appreciable gross lesions were collected from the abattoirs and subjected to pathological investigation for distribution of lesions/and types of exudates, as well as to molecular confirmation of bacterial and viral pathogens by PCR. The pneumonic lungs showed the higher prevalence of Mycoplasma spp.

Regulation of neuroinflammation in Alzheimer's disease via nanoparticle-loaded phytocompounds with anti-inflammatory and autophagy-inducing properties.

Background: Alzheimer's disease (AD) is characterized by neuroinflammation linked to amyloid β (Aβ) aggregation and phosphorylated tau (τ) protein in neurofibrillary tangles (NFTs). Key elements in Aβ production and NFT assembly, like γ-secretase and p38 mitogen-activated protein kinase (p38MAPK), contribute to neuroinflammation. In addition, impaired proteosomal and autophagic pathways increase Aβ and τ aggregation, leading to neuronal damage.

Diagnostic application of formalin fixed archived tissues for detection of foot-and-mouth disease.

Early and definitive disease diagnosis is critical for effective disease control. 50% buffered glycerine is commonly used viral transport medium, which is not always available and required cold chain. Tissues samples archived in 10% neutral buffered formalin (NBF) can preserve nucleic acid that can be used in molecular studies and disease diagnosis.

Estimation of microsatellite-based autozygosity and its correlation with pedigree inbreeding coefficient in crossbred cattle.

In countries where farming is largely subsistence, no pedigree records of farm animals are maintained at farmers' herd and scientific mating plans are not observed which leads to the accumulation of inbreeding and loss of production potential. Microsatellites have been widely used as reliable molecular markers to measure inbreeding. We attempted to correlate autozygosity estimated from microsatellite data with the inbreeding coefficient () calculated from pedigree data in Vrindavani crossbred cattle developed in India.

Multigroup prediction in lung cancer patients and comparative controls using signature of volatile organic compounds in breath samples.

Early detection of lung cancer is a crucial factor for increasing its survival rates among the detected patients. The presence of carbonyl volatile organic compounds (VOCs) in exhaled breath can play a vital role in early detection of lung cancer. Identifying these VOC markers in breath samples through innovative statistical and machine learning techniques is an important task in lung cancer research.

Pathomorphology, immunohistochemical, and molecular detection of an atypical porcine dermatitis and nephropathy syndrome (PDNS) due to PCV-2d-2 in naturally affected grower pigs of India.

Porcine circovirus type 2 (PCV-2) is of great economic significance to porcine industry worldwide. PCV-2 variants and genotypes, alternating world over, are the etiological agent of several clinical syndromes such as porcine dermatitis and nephropathy syndrome (PDNS), post-weaning multi-systemic wasting syndrome (PMWS) and others in pigs. This study is reporting an atypical manifestation of PDNS in twelve grower pigs, 3- to - 4.

Differential Expression Analysis of Single-Cell RNA-Seq Data: Current Statistical Approaches and Outstanding Challenges.

With the advent of single-cell RNA-sequencing (scRNA-seq), it is possible to measure the expression dynamics of genes at the single-cell level. Through scRNA-seq, a huge amount of expression data for several thousand(s) of genes over million(s) of cells are generated in a single experiment. Differential expression analysis is the primary downstream analysis of such data to identify gene markers for cell type detection and also provide inputs to other secondary analyses.

Effect of inhibition of Toll-like receptor 3 signaling on pathogenesis of rabies virus in mouse model.

Rabies is a zoonotic viral disease with inevitably fatal outcome. Toll-like receptor 3 (TLR3) could sense dsRNA viral infections, and implicated in pathogenesis of rabies and Negri bodies (NBs) formation. Present study was undertaken to elucidate the role of TLR3 in pathogenesis, NBs formation, and therapeutic potential of blocking TLR3/dsRNA interaction in rabies infection.

Novel pathological findings and immunohistochemical detection of FMDV antigens in the brain of calves naturally infected with foot-and-mouth disease.

Foot-and-mouth disease (FMD) is an extremely contagious and economically devastating viral disease of cloven-hoofed domestic and wildlife animals. The disease is endemic in India and other developing countries of the world. The disease is mainly characterized by the presence of vesicular lesions and "tigroid heart" in calves.

One-step SYBR green-based real-time RT-PCR assay for detection of foot-and-mouth disease virus circulating in India.

Rapid, sensitive, and reliable laboratory detection of foot-and-mouth disease virus (FMDV) infection is essential for containing and controlling virus infection in any geographical area. In this report a SYBR green-based 3D-specific one-step real-time RT-PCR (rRT-PCR) assay was developed for the pan-serotype detection of FMDV in India. The detection limit of the SYBR green-based rRT-PCR was 10 TCID/50 µl, which is 10 times more sensitive than the traditional agarose gel electrophoresis-based RT-multiplex PCR (RT-mPCR).

Regenerated silica-based RNA purification columns to address the short supply of RNA purification kits for COVID-19 diagnosis.

Background: RT-qPCR technique is the current world-wide method used for the early detection of SARS-CoV2 RNA in the suspected clinical samples. Viral RNA extraction is the key pre-analytical step for SARS-CoV2 detection which often achieved using commercial RNA-extraction kits. However, due to the COVID-19 pandemic, bulk production and the supply chains for the commercial RNA-extraction kit have been seriously compromised.

Short communication: preliminary observations on the serum levels of HSP70 and its correlation with serum cortisol, thyroid hormones, and acute-phase protein concentration in cattle naturally infected with foot-and-mouth disease virus.

The study aimed to explore the serum levels of HSP70 and identify its possible association with serum cortisol, thyroid hormones, and acute-phase protein concentrations in cattle naturally infected with foot-and-mouth disease (FMD) virus. After the FMD outbreak in an organized dairy cattle farm in India, blood samples were obtained from clinically infected (n = 40) and apparently healthy (n = 30) animals. Samples were processed and tested by an in-house DIVA assay for confirmation of FMD infection.
