De Novo Design of Lipopeptide-Based β-Sheet-Like Self-Assemblies: A Strategy to Develop Fusion Inhibitors as Broad-Spectrum Antivirals.

The recent surge in emerging viral infections warrants the design of broad-spectrum antivirals. We aim to develop a lead molecule that targets a common biochemical feature of many enveloped viruses, membrane fusion. To achieve the broad-spectrum ability, instead of targeting the fusion machinery, we plan to modulate the physicochemical properties of the host and viral membranes to block fusion.

"TB drug stock planning in advance is a futile activity" health system's perceived challenges and suggested solutions pertaining to Nikshay Aushadhi portal in central India.

Background: The National TB elimination programme (NTEP) is facilitating sub-national certification of "TB Free" status with benchmarks at every 20% reduction in incidence from the baseline of 2015. Drug consumption/sale is essential criteria to claim for the award. During the certification process in 10 districts of Madhya Pradesh in 2022, it was found that Nikshay Aushadhi (a web-based supply chain management portal) entries were incomplete or vacant in most of the districts and it was observed that quarterly drug requests were not sent using Nikshay Aushadhi.

Length-weight relationship and condition factor of Nile tilapia ( ) fed diets supplemented with guava and star gooseberry leaf extract.

Background: Nile tilapia ( ) is predominant cultured species in aquaculture. However, there is a scarcity of literature regarding relationship between guava and star gooseberry leaf extract and the condition factor. Thus, the present study aims to investigate the effect of guava and star gooseberry leaf extract-supplemented diets on the specific growth rate, length-weight relationship, and condition factor of Nile tilapia.

Bimetallic nanoparticles with sulfated galactan eliminate Vibrio parahaemolyticus in shrimp Penaeus vannamei.

Bimetallic (Au/Ag) nanoparticles (BNPs) have shown enhanced antibacterial activity compared to their monometallic counterparts. Sulfated galactans (SG) are a naturally occurring polymer commonly found in red seaweed Gracilaria fisheri. They are biocompatible and biodegradable and environmentally friendly.
