The effect of recombinant bovine somatotropin (bST) on the chemiluminescence, diapedesis, and expression of adhesion receptors (CD11a, CD11b, CD18) of isolated polymorphonuclear leukocytes was studied. The plasma concentrations of insulin-like growth factor-I (IGF-I), bST, cortisol, and alpha-lactalbumin were also monitored. In addition, general and local clinical symptoms and the differentiati...

Growth hormone (somatotropin—STH) deficiency therapy requires daily injections of recombinant human growth hormone. The FDA approved treatment with STH one dose per week for the first time in 2021. However, injectable drug application is accompanied by numerous inconveniences. Therefore, an attempt was made to formulate a less invasive formulation topical skin. A substrate prepared based on pol...

Background: Bovine follicle-stimulating hormone (bFSH) is a heterodimer hormone that consists of a common -subunit which noncovalently associated with the hormone-specific -subunit. During the past 15 years, the methylotrophic yeast Pichia pastoris has become an important host organism for recombinant protein production because it is able to use methanol as a sole carbon and energy source. Th...

with the plasmid dna from a clinical isolate of enterotoxigenic escherichia coli (etec) h 10407 as template, pcr-mediated cloning of the sequence encoding the heat-labile toxin b subunit (l t -b) has been carried out. then this sequence was recloned into the ptrc 99a and pet23a expression vectors to give the pjasmids ptrcltb and petltb, respectively. after induction, the former plasmid provides...
