The various types of glomerulonephritis, including many forms of vasculitis, are responsible for about 15% of cases of end-stage renal diesease (ESRD). Arterial hypertension represents a frequent finding in patients suffering from glomerulonephritis or vasculitis and hypertension also serves as an indicator for these severe types of diseases. In addition, ...

Primary hyperoxaluria Type 1 is a rare autosomal recessive inborn error of glyoxylate metabolism, caused by a deficiency of the liver-specific enzyme alanine:glyoxylate aminotransferase. The disorder results in overproduction and excessive urinary excretion of oxalate, causing recurrent urolithiasis and nephrocalcinosis. As glomerular filtration rate declines due to progressive renal involvement, ...

The highly conserved HIV-1 gp41 "pocket" region is a promising target for inhibiting viral entry. PIE12-trimer is a protease-resistant trimeric D-peptide inhibitor that binds to this pocket and potently blocks HIV entry. PIE12-trimer also possesses a reserve of binding energy that provides it with a strong genetic barrier to resistance ...
