Exploring the Pathophysiology of Henoch-Schönlein Purpura (HSP): A Comprehensive Review
Abstract: Blood from tiny veins can leak into nearby tissues, causing purpura, a disorder marked by red spots or patches on the skin that may have an impact on the kidneys. Henoch-Schönlein purpura (HSP) is associated with vasculitis and inflammation of blood vessels. The range of renal conditions associated with purpura includes severe glomerulonephritis and mild proteinuria. For instance, immunological complex accumulation in the renal glomeruli of HSP patients might result …

Association of Vitamin D Binding Protein BP rs2282679 Gene Polymorphism and Serum Levels of Vitamin D in Patients with Vitiligo
Abstract: For vitamin D to have an impact, the vitamin D receptor (VDR) must be expressed and activated in the nucleus. The VDR has several known genetic variants. Biological impacts can be caused by changes in DNA sequences known as "polymorphisms" that are common in the population. Vitiligo is a disease that causes loss of skin color in patches, and it is a chronic (long-lasting) autoimmune disorder loss of color. The …

Use of Geopolymer Composites for Controlling Structural Cracks
Abstract: A building’s safety and stability can be compromised by ignoring the potential structural issues indicated by occurring cracks in buildings. Extensive damage may cause over the period from unidentified cracks.Good quality concrete never cracks in normal service conditions unless high horizontal force is applied. Through the cracks, carbon dioxide is released into the concrete and speeds up carbonation throughout the cracks, thus reducing the structure usage. The materials which are …
