The Ti6Al4V alloy is widely recognized for its extensive industrial applications, particularly in the aeronautics sector, due to its exceptional strength to-weight ratio and corrosion resistance. In this context, many industrial processes depend critically on surface area, topology, and roughness. A promising approach involves combining Ti6Al4V alloy with polymer composites, which offers significant potential for engineers to design parts that are not only high-performing but also environmentally friendly.

Water Res
December 2024
Arsenic (As) enrichment in groundwater stems from natural and hydrogeochemical factors, leading to geological contamination. Groundwater and surface water are interconnected, allowing As migration and surface water contamination. The As contamination poses health risks through contaminated water consumption.

- Paropsisterna bimaculata is a harmful pest for eucalyptus trees, leading to significant defoliation and even tree death in Tasmanian plantations, impacting wood production.
- The study focused on creating an ecoclimatic index model using CLIMEX software to predict where this pest might spread globally, identifying high-risk areas for eucalyptus crops.
- Results indicated that regions with temperate climates across Asia, Africa, Europe, Oceania, and America are especially vulnerable, with a notable risk present in Brazil's southern and southeastern areas, guiding prevention strategies.
Early exposure to a cholinergic receptor blocking agent mitigates adult obesity and protects pancreatic islet function in male rats.
Am J Physiol Endocrinol Metab
January 2025
We tested the hypothesis that attenuation of the circulating insulin level in rats during early life can provide sustained protection against diet-induced obesity and metabolic dysfunction in adulthood. Male Wistar rats received intraperitoneal scopolamine butylbromide (SB) during the first 12 days of suckling, whereas control rats received 0.9% saline injections.

There is scarce data in the literature on survival of these patients, especially in upper and lower middle-income countries. We aimed to describe the clinical and demographic characteristics, treatment, and outcome of pediatric patients with ependymoma admitted to a public cancer hospital.
