Ocular microbial infection has emerged as a major public health crisis during the past two decades. A variety of causative agents can cause ocular microbial infections; which are characterized by persistent and destructive inflammation of the ocular tissue; progressive visual disturbance; and may result in loss of visual function in patients if early and effective treatments are not received. The conventional therapeutic approaches to treat vision impairment and blindness resulting from microbial infections involve antimicrobial therapy to eliminate the offending pathogens or in severe cases; by surgical methods and retinal prosthesis replacing of the infected area...

MAS receptor (MASR), expressed in several brain areas, conferred neuroprotection against neurodegenerative disorders when activated by angiotensin (Ang) 1-7; however, its role in Parkinson's disease (PD) remains elusive. Intra-striatal post-administration of Ang1-7, using a 6-hydroxydopamine (OHDA) PD model, improved motor performance and muscle coordination. On the molecular level, Ang1-7 upregulated the striatal expression of MASR and caused upsurge in its downstream targets (p-PI3K/p-Akt/p-CREB/BDNF) to phosphorylate TrKB, which in a positive feedback upregulates MASR...

Staphylococcus aureus is a major cause of nosocomial infections and secretes a diverse spectrum of virulence determinants as well as forms biofilm. The emergence of antibiotic-resistant S. aureus highlights the need for alternative forms of therapeutics other than conventional antibiotics. One route to meet this need is screening small molecule derivatives for potential anti-infective activity. Using a previously optimized C. elegans - S. aureus small molecule screen, we identified a benzimidazole derivative, UM-C162, which rescued nematodes from a S...
