Article Synopsis
- Viperid snake venoms contain metalloproteinases like barnettlysin-III (Bar-III), which cause bleeding and disrupt blood clotting and tissue integrity in victims.
- Bar-III, a specific type of metalloproteinase, has been characterized in terms of its properties, including its activity being enhanced by calcium and inhibited by zinc, and its ability to degrade important blood and tissue proteins.
- The study also highlights Bar-III’s effects on platelets and endothelial cells, suggesting that it affects platelet aggregation and cell adhesion, providing insights that could lead to new treatments for snakebite envenomation.
Burns in the elderly are a public health concern. This study aimed to analyze etiology, clinical characteristics, and independent risk factors for outcomes of burns in elderly patients. This retrospective study included elderly patients (65 years and over) admitted to a major burn unit between 2006 and 2016.

The resistance to chlorine-based sanitizers, ability to attach to stainless steel surfaces, and antibiogram profile of a large set of S. aureus strains (n = 585) were assessed.
