Carbohydrates play pivotal roles in the first stages of microbial infections and can be exploited as decoys to hijack the interactions between bacteria and the host cell. Multivalent glycan probes mimicking the natural presentation of glycans in living cells have been successfully employed to study fundamental carbohydrate/protein interactions in microbial systems; however, most pathogenic glycan receptors exhibit a shared specificity for commonly found sugars present in both healthy and pathogenic cells, posing a challenge for target selectivity. In this study, we report the synthesis of a small library of d-arabinose multivalent probes, a sugar absent in human physiology, and their evaluation in a bacteria agglutination assay using cluster analysis.

Article Synopsis
  • Sperm capacitation occurs in the female reproductive tract and enables sperm to fertilize an egg through a series of biochemical changes, which can be replicated in lab settings with specific nutrients.
  • Genetic studies highlight the essential role of the K channel SLO3 in this process, with infertility observed in mice lacking SLO3 expression and two critical events—sperm hyperpolarization and intracellular alkalinization—being fundamental to capacitation.
  • The study reveals that Na/H exchangers (NHEs) are vital for sperm membrane hyperpolarization during capacitation, with particular focus on the sperm-specific NHE (sNHE) and its interaction with cyclic AMP, underscoring their importance in the activation of SLO3.

Although global vaccination campaigns alleviated the SARS-CoV-2 pandemic in terms of morbidity and mortality, the ability of the virus to originate mutants may reduce the efficacy of vaccines, posing a serious risk of a renewed pandemic. There is therefore a need to develop small molecules capable of targeting conserved viral targets, such as the main protease (M). Here, a series of benzisoselenazolones and diselenides were tested for their ability to inhibit M; then the most potent compounds were measured for antiviral activity in vitro, and the mechanism of action was investigated.

Purpose: Radiofrequency ablation has been used to treat chronic shoulder pain with mixed results. Thanks to recent anatomical studies, the precise location of articular branches of the suprascapular, lateropectoral and axillary nerves has been determined. Cooled radiofrequency is a neuroablative modality of treatment which has been demonstrated as efficient in different anatomical locations, and targeting the aforementioned nerves could result in a complete and efficient denervation of the shoulder.
