Eco-Friendly Synthesis of Zirconium Dioxide Nanoparticles from : Applications in Dye Degradation, Antioxidant and Antibacterial Activity.

Zirconium dioxide nanoparticles (ZrO NPs) have gained significant attention due to their excellent bioavailability, low toxicity, and diverse applications in the medical and industrial fields. In this study, ZrO NPs were synthesized using zirconyl oxychloride and the aqueous leaf extract of as a stabilizing agent. Analytical techniques, including various spectroscopy methods and electron microscopy, confirmed the formation of aggregated spherical ZrO NPs, ranging from 15 to 30 nm in size, with mixed-phase structure composed of tetragonal and monoclinic structures.

Intranasal delivery of metformin using metal-organic framework (MOF)-74-Mg nanocarriers.

Dosage tolerance is one of the translational challenges of using metformin (Met) in brain therapeutics. This paper presents metal-organic framework (MOF)-74-Mg nanocarriers (NCs) for intranasal (IN) delivery of brain-specific agents with a prolonged release time. We confirmed their excellent biocompatibility (5 mg/mL) and intrinsic fluorescence properties (370/500 nm excitation/emission peak) in Neuro-2A cells.

Enhancing prediction and inference of daily in-stream nutrient and sediment concentrations using an extreme gradient boosting based water quality estimation tool - XGBest.

Estimating constituent loads in streams and rivers is a crucial but challenging task due to low-frequency sampling in most watersheds. While predictive modeling can augment sparsely sampled water quality data, it can be challenging due to the complex and multifaceted interactions between several sub-watershed eco-hydrological processes. Traditional water quality prediction models, typically calibrated for individual sites, struggle to fully capture these interactions.

Expert consensus and recommendations on the live attenuated hepatitis A vaccine and immunization practices in India.

While Hepatitis A Virus (HAV) vaccination in global immunization programs has shown a virtual elimination of the disease within few years of the vaccination program, changing epidemiological landscape in India underscores the need for evidence-based, updated guidance on immunization practices. In May 2024, a panel of 15 distinguished opinion leaders and an organizing committee convened for an intensive, face-to-face advisory board meeting on high burden of HAV infection among adults, increased mortality rate in adolescents, symptomatic presentation in children, and evolving landscape globally and within India. Extensive comparable deliberations on long-term follow-up data from India and data from country of origin advocated immunogenicity, tolerability, and long-term protective effects of single-dose live attenuated HAV vaccine in children.

Diversity, abundance, and domain architecture of plant NLR proteins in .

The resistance () gene family in plants is a vital component of the plant defense system, enabling host resistance against pathogens through interactions with pathogen effector proteins. These R genes often encode nucleotide-binding (NB-ARC or N) and leucine-rich-repeat (LRR or L) domains, collectively forming the NLR protein family. The NLR proteins have been widely explored in crops from and , but limited studies are available for crops in other families, including .
