Article Synopsis
- Greenhouse gas emissions are primarily responsible for rising global temperatures, with Brazil's major contributions coming from forestry, land use, and agriculture sectors.
- The study analyzed two GHG inventories (Climate TRACE and SEEG) to assess carbon removal's impact on Brazil's national emissions and investigated how seasonal factors like precipitation and photosynthesis affect these estimates.
- Results showed significant differences in GHG inventory estimates, especially in the forestry sector, with the Caatinga biome contributing nearly 50% to Brazil's carbon removals in 2022, emphasizing the importance of halting deforestation for achieving net-zero emissions.
The development of new wound dressings made from biomaterials, which offer a better cost-benefit ratio and accelerate the healing process, is increasing nowadays. Various biopolymers can be electrospun to form functional membranes for wound healing. Therefore, in this study, chitosan and nanochitosan membranes with or without hyaluronic acid were prepared using the electrospinning technique, characterized and evaluated in the healing of skin wounds in rats.

Methods: Diabetes was induced in female Wistar rats 24 h after birth through the administration of Streptozotocin. The diabetic condition of the rats was further confirmed in adulthood.
The Blood-Brain Barrier in Both Humans and Rats: A Perspective From 3D Imaging.
Int J Biomed Imaging
August 2024
Article Synopsis
- - The study focuses on imaging the blood-brain barrier (BBB) using advanced techniques in order to better understand its 3D structure in both human and rat brain tissue.
- - Researchers used the CUBIC clearing method along with confocal and two-photon microscopes to visualize and reconstruct the BBB, revealing uneven expression of certain proteins in human brain endothelial cells.
- - Findings indicated that astrocytes only partially cover blood vessels, highlighting significant structural differences between the 3D BBB and previously understood 2D models, and suggesting that tissue clearing and 3D imaging could enhance our understanding of biological structures.
This study aims to evaluate the phytochemical properties of Bauhinia holophylla (Bong.) Steud leaf extract, and their impact on maternal reproductive and fetal development in diabetic rats. For this, adult female Wistar rats (100 days of life) received streptozotocin (40 mg/Kg, intraperitoneal) for induction of diabetes, were mated and distributed into four groups: Nondiabetic; Nondiabetic given B.
