DNA damage and ALAD polymorphism in high blood lead (Pb) levels of pregnant women attending a tertiary care teaching hospital.

Background: Pregnant women are particularly vulnerable to lead toxicity due to increased absorption and decreased elimination of lead from their bodies. The δ-aminolevulinic acid dehydratase (ALAD) gene plays a crucial role in lead metabolism, and its polymorphisms have been implicated in modifying the susceptibility to lead toxicity.

Methods: A cross-sectional study was conducted involving 90 pregnant women and blood samples were collected to measure blood lead levels (BLL) and assessed DNA damage using the comet assay.

Mapping malaria vectors and insecticide resistance in a high-endemic district of Haryana, India: implications for vector control strategies.

Background: Achieving effective control and elimination of malaria in endemic regions necessitates a comprehensive understanding of local mosquito species responsible for malaria transmission and their susceptibility to insecticides.

Methods: The study was conducted in the highly malaria prone Ujina Primary Health Center of Nuh (Mewat) district of Haryana state of India. Monthly entomological surveys were carried out for adult mosquito collections via indoor resting collections, light trap collections, and pyrethrum spray collections.

There is a paucity of robust evidence from qualitative studies on the acceptability and expectations of potential recipients from the COVID-19 vaccine around the time of its rollout in India. We conducted this study to explore the acceptance and expectations of the COVID-19 vaccine among the healthcare workers and community in Bhavnagar, India.

Brain Mitochondria as a Therapeutic Target for Carnosic Acid.

Carnosic acid (CA), a diterpene obtained mainly from and , exerts antioxidant, anti-inflammatory, and anti-apoptotic effects in mammalian cells. At least in part, those benefits are associated with the ability that CA modulates mitochondrial physiology. CA attenuated bioenergetics collapse and redox impairments in the mitochondria obtained from brain cells exposed to several toxicants in both and experimental models.

Metagenomics analysis of mice gut microbiome to unravel the role of metal exposure and piperine.

The gut and intestinal microbiota consists of trillions of microorganisms inhabiting the human gastrointestinal tract. It plays a crucial role in human health leading to understanding the dynamic crosstalk of host-microbe interaction in the gut and has become necessary for the detection, prevention, or therapy of diseases. Gut microbiota deviations are linked with many diseases, suggesting that various pathways involved in immunity, energy, lipid, and glucose metabolism are affected.

Blood lead levels in pregnant women and their newborn infants at an Indian teaching hospital.

Background And Aim: With the growth of the world's economy and industrialization, lead (Pb) contamination in the environment has become a major issue on a global scale. Lead is typically linked to unfavorable pregnancy outcomes such as stillbirth, low birth weight preterm, and spontaneous abortion. In this study, we evaluated the blood lead levels of pregnant women and their birth outcomes attending an Indian tertiary care teaching hospital, those who were not exposed to any lead-associated industry or shops.

Prevalence and predictors of high-frequency hearing loss among mine workers in Gujarat, western India: a cross-sectional study on the need to implement a comprehensive hearing conservation program.

Background: High-frequency hearing loss (HFHL) stands as a prevalent occupational morbidity globally, with numerous associated risk factors, some of which are modifiable. In the context of a comprehensive hearing conservation program, the initial steps involve early screening and identification of workers with these modifiable risk factors, aiming to reduce the prevalence of hearing loss. Our objective was to estimate the prevalence of HFHL and determine its predictors among mine workers.

Reproducibility is a preferred aim in any scientific research, including occupational health research. Datamanagement is an important and essential step in marching towards reproducibility. A good datamanagement helps us stay organized, improve transparency, quality and fosters collaboration.

ABDpred: Prediction of active antimicrobial compounds using supervised machine learning techniques.

Background Objectives: Discovery of new antibiotics is the need of the hour to treat infectious diseases. An ever-increasing repertoire of multidrug-resistant pathogens poses an imminent threat to human lives across the globe. However, the low success rate of the existing approaches and technologies for antibiotic discovery remains a major bottleneck.

Artificial intelligence in advancing occupational health and safety: an encapsulation of developments.

Objectives: In an era characterized by dynamic technological advancements, the well-being of the workforce remains a cornerstone of progress and sustainability. The evolving industrial landscape in the modern world has had a considerable influence on occupational health and safety (OHS). Ensuring the well-being of workers and creating safe working environments are not only ethical imperatives but also integral to maintaining operational efficiency and productivity.

Intranasal immunization of mice with chimera of Salmonella Typhi protein elicits protective intestinal immunity.

Development of safe, highly effective and affordable enteric fever vaccines is a global health priority. Live, oral typhoid vaccines induce strong mucosal immunity and long-term protection, but safety remains a concern. In contrast, efficacy wears off rapidly for injectable, polysaccharide-based vaccines, which elicit poor mucosal response.

A candidate glycoconjugate vaccine induces protective antibodies in the serum and intestinal secretions, antibody recall response and memory T cells and protects against both typhoidal and non-typhoidal serovars.

Human infections pose significant public health challenges globally, primarily due to low diagnostic yield of systemic infections, emerging and expanding antibiotic resistance of both the typhoidal and non-typhoidal strains and the development of asymptomatic carrier state that functions as a reservoir of infection in the community. The limited long-term efficacy of the currently licensed typhoid vaccines, especially in smaller children and non-availability of vaccines against other serovars necessitate active research towards developing a multivalent vaccine with wider coverage of protection against pathogenic serovars. We had earlier reported immunogenicity and protective efficacy of a subunit vaccine containing a recombinant outer membrane protein (T2544) of Typhi in a mouse model.
