Article Synopsis
- * Cornea xenotransplantation using porcine corneas is a potential solution due to the cost-effectiveness and biological compatibility, but there are ethical issues and immune rejection concerns that need to be addressed.
- * Recent advancements in genetic engineering and new immunosuppressive techniques are showing promise in increasing the success rate of porcine corneal transplants, highlighting the need for ongoing research to improve safety and effectiveness.
Phα1β is a neurotoxin purified from spider venom that acts as a high-voltage-activated (HVA) calcium channel blocker. This spider peptide has shown a high selectivity for N-type HVA calcium channels (NVACC) and an analgesic effect in several animal models of pain. Its activity was associated with a reduction in calcium transients, glutamate release, and reactive oxygen species production from the spinal cord tissue and dorsal ganglia root (DRG) in rats and mice.

Histiocytes can pose a significant challenge in serous fluid cytology as they tend to appear atypical due to prolonged accumulation in serous fluids in vivo and processing by liquid-based cytology in vitro. Not many studies have documented the utilization of histiocytic marker such as CD68 in serous fluid cytology, which can subsequently reduce the "atypical" diagnostic category.

Hundreds of mutations and non-coding haplotypes in the GLA gene have been described; however, many are variants of unknown significance, prompting doubts about the diagnosis and treatment. The α-Galactosidase A enzymatic activity in dried blood spot (DBS) samples are widely used for screening purposes; however, even when values below the normal are found, new tests are required to confirm the diagnosis.
View Article and Find Full Text PDFBackground: Fabry disease (FD) is a rare X-linked storage disorder resulting from the deficient activity of the lysosomal hydrolase α-galactosidase A (α-Gal A). Here we describe a 23-year-old man with FD possessing a novel mutation in the GLA gene, the evaluation of his family, and the functional characterization of the novel variant.
Methods: Two generations of a family were screened for FD by clinical symptoms and low enzymatic activity.
