Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Putrescine stimulates chemiosmotic ATP synthesis

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
Putrescine is a main polyamine found in animals, plants and microbes, but the molecular mechanism underlying its mode of action is still obscure. In vivo chlorophyll a fluorescence in tobacco leaf discs indicated that putrescine treatment affects the energization of the thylakoid membrane.

4-Aminobutyrate in mammalian putrescine catabolism [PDF]

open access: yesBiochemical Journal, 1975
The effects of inhibitors of diamine oxidase (EC 1.4.3.6), monoamine oxidase (EC 1.4.3.4) and 4-aminobutyrate aminotransferase (EC 2.6.1.19) on the catabolism of putrescine in mice in vivo were studied. Diamine oxidase inhibitors and carboxymethoxylamine (amino-oxyacetate) markedly inhibit the metabolism of [14C]putrescine to 14CO2, but affect ...

Influence of postharvest putrescine application on respiration rate and physicochemical properties of tomato

open access: yesBMC Plant Biology
Background Tomato (Solanum lycopersicum L.) is a species of vegetable that is widely consumed worldwide and has high nutritional value. However, during storage, quality losses occur, especially water loss, decay, acidity loss and vitamin reduction.

Putrescine biosynthesis in Tetrahymena thermophila [PDF]

open access: yesBiochemical Journal, 1984
The putrescine-biosynthesis pathway in Tetrahymena thermophila was delineated by studying crude extracts prepared from exponentially growing cultures. A pyridoxal phosphate-stimulated ornithine decarboxylase activity competitively inhibited by putrescine was detected. CO2 was also liberated from L-arginine, but analyses by t.l.c.

Protective Effects of Potential Probiotic Pediococcus acidilactici 100 Against Multi‐Drug‐Resistant Diarrheal Escherichia coli Strains Induced Changes in Caenorhabditis elegans Model System

open access: yesFood Safety and Health, EarlyView.
This study shows the protective effects of potential probiotic strain of Pediococci strains against diarrheal Escherichia coli strains in Caenorhabditis elegans model system. The E. coli strains resulted in severe morphological and physiological damage to the worm whereas the probiotic interventions were able to reduce these damages.
