Differences in Polyamine Metabolism between Carcinomatous and Uninvolved Human Breast Tissues
The International Journal of Biological Markers, 1986 The polyamine biosynthetic enzymes ODC and SAMDC show higher activity in carcinomatous human breast tissue than in uninvolved tissue of the same breast; the interconversion enzyme PAO shows significantly lower activity in carcinomatous than uninvolved ...

Medium alkalization due to carbon metabolism is largely responsible for inhibition of bacterial growth by Vibrio cholerae supernatants [PDF]
, 2017 Vibrio cholerae is the causative agent of the diarrheal disease cholera. Many Vibrio species secrete antimicrobial factors, though the identity of such a factor has not been determined for any V. cholerae strain.

Cyclosporine augments hepatic regenerative response in rats [PDF]
, 1990 A number of mechanisms participate in the hepatic injury that occurs during and following liver transplantation. A normal allograft regenerative response is probably essential for a successful transplant outcome. In this study, the effect of cyclosporine,

Animal Research and One Health, EarlyView.Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
