De novo design of peptide binders to conformationally diverse targets with contrastive language modeling.

Designing binders to target undruggable proteins presents a formidable challenge in drug discovery. In this work, we provide an algorithmic framework to design short, target-binding linear peptides, requiring only the amino acid sequence of the target protein. To do this, we propose a process to generate naturalistic peptide candidates through Gaussian perturbation of the peptidic latent space of the ESM-2 protein language model and subsequently screen these novel sequences for target-selective interaction activity via a contrastive language-image pretraining (CLIP)-based contrastive learning architecture.

Routine Fundoscopy: Unravelling Undiagnosed Significant Coarctation of the Aorta.

A 10-year-old boy was brought to the outpatient department with complaints of diminished vision for two years. On examination, the best-corrected visual acuity (BCVA) in oculus dexter (OD) was 20/40 and in oculus sinister (OS) was 20/80. The patient was dilated for routine fundoscopy, which revealed grade IV hypertensive retinopathy changes in both eyes, with a macular fan in the left eye.

Combatting Salmonella: a focus on antimicrobial resistance and the need for effective vaccination.

Background: Salmonella infections represent a major global public health concern due to their widespread zoonotic transmission, antimicrobial resistance, and associated morbidity and mortality. This review aimed to summarize the zoonotic nature of Salmonella, the challenges posed by antimicrobial resistance, the global burden of infections, and the need for effective vaccination strategies to mitigate the rising threat of Salmonella.

Methods: A systematic review of literature was conducted using databases such as PubMed, Scopus, Web of Science, and Google Scholar.

Nanoparticle Interactions with the Blood Brain Barrier: Insights from Drosophila and Implications for Human Astrocyte Targeted Therapies.

This review explores the intricate connections between Drosophila models and the human blood-brain barrier (BBB) with nanoparticle-based approaches for neurological treatment. Drosophila serves as a powerful model organism due to its evolutionary conservation of key biological processes, particularly in the context of the BBB, which is formed by glial cells that share structural and functional similarities with mammalian endothelial cells. Recent advancements in nanoparticle technology have highlighted their potential for effective drug delivery across the BBB, utilizing mechanisms such as passive diffusion, receptor-mediated transcytosis, and carrier-mediated transport.

Metal-organic framework catalysed multicomponent reactions towards the synthesis of Pyrans.

Metal-Organic Frameworks (MOFs) gaining increasing interest in heterogeneous catalysis owing to their advantageous properties such as superior porosity, high surface area, ample catalytic sites. Their properties can be tailored by varying the metal ions or metal clusters (nodes) and organic linkers. Magnetically active nano core-shell MOF composites are also discovered for easy separation and reuse of catalyst.
