Haemoprotozoan and haemorickettsial carrier status in pet and community owned dogs of south India.

The increasing population of dogs and changes in the climatic conditions have resulted in the emergence and re-emergence of vector-borne diseases in canines. These vectors borne diseases in canines pose a diagnostic challenge to the field veterinarians because of co-infections with several pathogens. Comprehensive data on the prevalence of haemoparasites and haemorickettsiales in pet and community owned dogs from south India are scant.

Carboplatin-loaded zeolitic imidazolate framework-8: Induction of antiproliferative activity and apoptosis in breast cancer cell.

The challenge with breast cancer is its ongoing high prevalence and difficulties in early detection and access to effective care. A solution lies in creating tailored metal-organic frameworks to encapsulate anticancer drugs, enabling precise and targeted treatment with less adverse effects and improved effectiveness. Zeolitic imidazolate framework-8 (ZIF-8) and carboplatin (CP)-loaded ZIF-8 were synthesized and characterized using various analytical techniques.

Molecular detection and characterisation of species in community owned dogs of Kerala, a South Indian State.

Haemotropic mycoplasmas (haemoplasmas) are obligate epierythrocytic bacteria that infect a wide range of vertebrate hosts. The molecular characterisation of  organisms in dogs has not previously been attempted from India. Hence, in the present study, the molecular characterisation of  spp.

Safety and efficacy of CRISPR-mediated genome ablation of VEGFA as a treatment for choroidal neovascularization in nonhuman primate eyes.

CRISPR-based genome editing enables permanent suppression of angiogenic factors such as vascular endothelial growth factor (VEGF) as a potential treatment for choroidal neovascularization (CNV)-a major cause of blindness in age-related macular degeneration. We previously designed adeno-associated viral (AAV) vectors with S. pyogenes Cas 9 (SpCas9) and guide RNAs (gRNAs) to target conserved sequences in VEGFA across mouse, rhesus macaque, and human, with successful suppression of VEGF and laser-induced CNV in mice.

A network pharmacology-based approach to understand the mechanism of action of anti-mycobacterial activity of Acacia nilotica: a modelling and experimental study.

The rapid rise in drug-resistant tuberculosis poses a serious threat to public health and demands the discovery of new anti-mycobacterial agents. Medicinal plants are a proven potential source of bioactive compounds; however, identifying those responsible for the putative anti-mycobacterial action still remains a challenging task. In this study, we undertook a systematic network pharmacology approach to identify and evaluate anti-mycobacterial compounds from a traditional plant, Acacia nilotica, as a model system.

In vitro evaluation of acaricidal activity of eugenol and benzaldehyde against Rhipicephalus annulatus.

Economic importance of ticks for both humans and animals is significant primarily because of their involvement in disease transmission. The continuous use of synthetic chemical acaricides on animals and/or in the environment has resulted in the emergence of resistant tick populations. Consequently, there is a compelling need to explore newer natural alternatives that can address their adverse effects effectively.

Molecular characterization of infecting a primate in South India.

spp. is a mite-borne cestode parasite that inhabits the small intestine of wide range of mammals, including non-human primates. In the present study, the morphological and molecular analysis of recovered from the small intestine of a bonnet macaque () from Wayanad, Kerala (South India) was performed.

An exploratory deep learning approach to investigate tuberculosis pathogenesis in nonhuman primate model: Combining automated radiological analysis with clinical and biomarkers data.

Background: Tuberculosis (TB) kills approximately 1.6 million people yearly despite the fact anti-TB drugs are generally curative. Therefore, TB-case detection and monitoring of therapy, need a comprehensive approach.

Comparing machine learning screening approaches using clinical data and cytokine profiles for COVID-19 in resource-limited and resource-abundant settings.

Accurate screening of COVID-19 infection status for symptomatic patients is a critical public health task. Although molecular and antigen tests now exist for COVID-19, in resource-limited settings, screening tests are often not available. Furthermore, during the early stages of the pandemic tests were not available in any capacity.

Biomolecular condensates as drivers of membrane trafficking and remodelling.

Membrane remodelling is essential for the trafficking of macromolecules throughout the cell, a process that regulates various aspects of cellular health and pathology. Recent studies implicate the role of biomolecular condensates in regulating multiple steps of the membrane trafficking pathway including but not limited to the organization of the trafficking machinery, dynamic remodeling of membranes, spatial and functional regulation, and response to cellular signals. The implicated proteins contain key structural elements, most notably prion-like domains within intrinsically disordered regions that are necessary for biomolecular condensate formation at fusion sites in processes like endocytic assembly, autophagy, organelle biosynthesis and synaptic vesicle fusion.

Declining Levels of Neutralizing Antibodies to SARS-CoV-2 Omicron Variants Are Enhanced by Hybrid Immunity and Original/Omicron Bivalent Vaccination.

We determined neutralizing antibody levels to the ancestral Wuhan SARS-CoV-2 strain and three Omicron variants, namely BA.5, XBB.1.

Anticancer Effects of Ethanolic Extracts of Leaves on Human Oral Squamous Carcinoma Cell Lines: An Study.

Cancer is a disease resulting from the disruption of cell cycle regulation, leading to the abnormal and unchecked proliferation of cells. Medicinal plants are rich in various bioactive phytochemicals or nutritional compounds. The aim is to determine the cytotoxic and genotoxic effects of ethanolic extracts of leaves on human oral cancer cell lines.

Facile engineering of aptamer-coupled silk fibroin encapsulated myogenic gold nanocomposites: investigation of antiproliferative activity and apoptosis induction.

Nanocomposites selectively induce cancer cell death, holding potential for precise liver cancer treatment breakthroughs. This study assessed the cytotoxicity of gold nanocomposites (Au NCs) enclosed within silk fibroin (SF), aptamer (Ap), and the myogenic Talaromyces purpureogenus (TP) against a human liver cancer cell (HepG2). The ultimate product, Ap-SF-TP@Au NCs, results from a three-step process.

Evidence on Milk Consumption and Production Linkages from Rural Bihar, India.

Background: Milk is an important source of protein for many Indian households. However, milk intake is very low. Hence, it is necessary to examine production-consumption linkages of milk within the paradigm of accessibility, availability, and affordability.

Associations of the glycaemic index and the glycaemic load with risk of type 2 diabetes in 127 594 people from 20 countries (PURE): a prospective cohort study.

Background: The association between the glycaemic index and the glycaemic load with type 2 diabetes incidence is controversial. We aimed to evaluate this association in an international cohort with diverse glycaemic index and glycaemic load diets.

Methods: The PURE study is a prospective cohort study of 127 594 adults aged 35-70 years from 20 high-income, middle-income, and low-income countries.

Citizens protein project: A self-funded, transparent, and concerning report on analysis of popular protein supplements sold in the Indian market.

Protein powders, including those containing herbal and dietary supplements such as vitamins, minerals, and other natural or synthetic ingredients, can be associated with hepatotoxicity. Protein supplements are often mislabeled and deceptive in their contents. In this self-funded transparent study, we extensively analyzed popular protein supplements in India to identify potential hepatotoxic substances based on industrial standards.

Complementary and alternative medicines and liver disease.

Complementary and alternative medicines (CAM) include conventional medical treatments. Patients worldwide use CAM at alarming rates; thus, reports of CAM-related DILI have been on the rise. The clinical presentations include asymptomatic liver test abnormalities, acute hepatitis with or without jaundice, acute cholestatic liver disease (bland or with hepatitis), acute liver failure, severe hepatitis with features of portal hypertension, and acute decompensation of known or unknown cirrhosis that can lead to acute-on-chronic liver failure.
