Article Synopsis
- Bothrops snake venom causes serious local effects like pain, swelling, and bleeding; it's made up mostly of metalloproteinases and phospholipase A2 toxins.
- A study on 22 patients in Manaus highlighted common symptoms such as fang marks, infections, and blistering, along with specific skin changes like spongiosis and hyperkeratosis.
- The findings suggest that both the venom and the body’s inflammatory response contribute to skin damage, indicating a need for improved treatment strategies for snakebite victims.
Violence risk is a major challenge among acute psychiatric inpatients. The study aimed to predict violent behavior risk in an acute psychiatric ward using video recordings from the emergency department. 69 videos of the emergency department recording the first ten minutes following patients' arrivals were included.

In this context, wild animals can share energy wirelessly besides their data communications as they opportunistically come into range of each other. Our goal is to find a way to balance the energy among the nodes and minimize this energy loss.

- * A new fabrication technique has been developed to create flexible and stretchable piezoelectric fibers using a hybrid nanocomposite that can convert physical movements into electrical energy, offering high output voltage and power density.
- * Testing of the nanocomposite fibers shows they are non-toxic and compatible with human cells, making them promising candidates for smart biomedical devices and scaffolding in tissue engineering.
Background: Trace metals such as iron, nickel, copper, zinc, and cadmium (Fe, Ni, Cu, Zn, and Cd) are essential micronutrients (and sometimes toxins) for phytoplankton, and the analysis of trace-metal stable isotopes in seawater is a valuable tool for exploring the biogeochemical cycling of these elements in the ocean. However, the complex and often time-consuming chromatography process required to purify these elements from seawater has limited the number of trace-metal isotope samples which can be easily processed in biogeochemical studies. To facilitate the trace-metal stable isotope analysis, here, we describe a new rapid procedure that utilizes automated chromatography for extracting and purifying Ni and Cu from seawater for isotope analysis using a prepFAST-MC™ system (Elemental Scientific Inc.
