Escalating problems with drug resistance continue to compromise the effectiveness of commercial antibiotics, necessitating the search for novel classes of antimicrobial agents. To circumvent problems with resistance, a multitarget single-pharmacophore approach has been employed to discover inhibitors that possess balanced activity against multiple target enzymes. In this chapter, we examine the application of computational techniques, in particular, structure-based drug design approaches, to design new dual-targeting antibacterial agents against bacterial topoisomerases.

Intratumoral drug delivery systems hold immense promise in overcoming the limitations of conventional IV chemotherapy, particularly in enhancing therapeutic efficacy and minimizing systemic side effects. In this study, we introduce a novel redox-responsive intratumoral nanogel system that combines the biocompatibility of natural polysaccharides with the tailored properties of synthetic polymers. The nanogel features a unique cross-linked architecture incorporating redox-sensitive segments, designed to leverage the elevated glutathione levels in the tumor microenvironment for controlled drug release.

It is imperative to investigate more cost-effective, long-lasting, efficient, and reliable non-noble metal electrocatalysts for the oxygen evolution reaction (OER) in hydrogen production via water splitting. Metal-organic complexes have been extensively researched and utilized for this purpose, yet their transformation in this process remains intriguing and underexplored. To enable a comprehensive comparison, we synthesized three types of metal-organic complexes with varying morphologies using the same raw material.

Introduction: Undetectable equals untransmittable (U=U) is an education campaign promoting science that people living with human immunodeficiency virus (HIV) who maintain an undetectable viral load cannot transmit HIV to others. Researchers theorize that undetectable equals untransmittable messaging will decrease HIV stigma by reducing fears of HIV transmission and providing evidence to dismantle discriminatory policies. However, little is known about how people with HIV in South Africa interpret the results of their viral load tests, undetectable equals untransmittable messaging, or its impact on stigma.

Vasculogenic mimicry (VM) represents a novel form of angiogenesis discovered in numerous malignant tumours in recent years. Unlike traditional angiogenesis, VM facilitates tumour blood supply independently of endothelial cells by enabling tumour cells to form functional vascular networks. This phenomenon, where tumour cells replace endothelial cells to form tubular structures, plays a pivotal role in tumour growth and metastasis.

Macroscale neuroimaging results have revealed significant differences in the structural and functional connectivity patterns of gyri and sulci in the primate cerebral cortex. Despite these findings, understanding these differences at the molecular level has remained challenging. This study leverages a comprehensive dataset of whole-brain in situ hybridization (ISH) data from marmosets, with updates continuing through 2024, to systematically analyze cortical folding patterns.
