Barocaloric effects in barium-dicalcium propionate salts
… In this thesis, I synthesised barium dicalcium propionate and barium dicalcium butyrate and investigated their refrigerant properties. Using differential scanning calorimetry, I found the thermally driven entropy changes associated with the phase transition as ~39.6 J K-1 kg-1, for barium …

Mechanisms of Ionophore Toxicoses: Laidlomycin Propionate Toxicosis in the Horse and Monensin, Laidlomycin, and Laidlomycin Propionate in Muscle Cultures
Cellular effects of monensin, laidlomycin, and LP were evaluated after 24-hour exposure in 3-day (myoblasts) and 14-day ($>$90% myotubes) cultures of E-63 rat skeletal muscle cells. Each of these ionophores induced dose-dependent increases in lactate concentrations, decreases in pyruvate …

The effects of testosterone propionate on hindlimb immobilized rats
… received a daily injection of 5 mg testosterone propionate. The animals in group IV were not castrated but were casted.These rats also received a daily injection of testosterone. The duration of treatment was two weeks for each rat. Body weights were measured before and after treatment. The …

Semi-biological domino catalysis using acetate- and propionate-producing microbes
… waste streams, can be converted into acetate and propionate, respectively, via microbial fermentation. This thesis demonstrates new production routes to acetate and propionate utilising acetate-producing (acetogenic) and propionate-producing (propionic acid) bacteria. Acetogenic bacteria require …

Supplementation of Chromium Propionate Positively Impacts Reproductive Performance of Beef Females
… the effects of supplementing Chromium propionate (CrP) during the peripartum until weaning on productive and reproductive performance in Bos taurus beef cows. In Exp. 1, 62 Angus-based beef cows were stratified by predicted calving date, body weight (BW) and randomly assigned to one of …

Effect of feeding calcium propionate on carcass composition, and productive performance of male broilers
… diet and diets with 1.5% and 2.7% calcium propionate (CaP). Broiler diets were supplemented with CaP for the first 2,4,6, or 8-week intervals. After being fed CaP for the previous mentioned times the broilers received a control diet for the remainder of each period. All broilers …

Propionate induces gluconeogenesis in dairy cattle through direct activation of the bovine cytosolic phosphoenolpyruvate carboxykinase gene promoter
… cows, a condition linked to increased ruminal propionate production. The central hypothesis of this dissertation is that propionate regulates its own metabolism in liver of dairy cattle through regulation of the PCK1 gene. The objectives of this dissertation were to determine: 1) the effect of …

The effect of propofol on α‐amino‐5‐methyl‐4‐isoxazole propionate(AMPA) induced neurotoxicity in rat mixed cortical cultures
BACKGROUND: Excessive extracellular glutamate accmulation due to cerebral ischemia is belived to induce excitotoxic cascade by overstimulation of glutamate receptors such as Nmethyl- D-aspartate (NMDA), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), and kainite. The pattern of AMPA …

Studying the Effect of Zinc 3-(Dibutylamino) Propionate (ZDAP) Additive on Fire Retardant, Mechanical, and Physical Characteristics of Epoxy-Amine Networks
… research group developed zinc 3-(dibutylamino)propionate (ZDAP) as a fire-retardant additive. This zinc-salt-based fire retardant is an endothermically-degrading char former that is functionalized with tertiary amines that allow for its dissolution in epoxy-amine. As a result, ZDAP-loaded EANs …

Evaluation of Granulation Processes in Upflow Anaerobic Sludge Blanket Reactors Using Oligonucleotide Probe Hybridizations
The potentials for Methanosaeta concilii and propionate-degrading syntrophic consortia to serve as nuclei for granulation were evaluated by monitoring granulation processes starting from non-granular sludge in two laboratory-scale upflow anaerobic sludge blanket reactors (Reactor G and Reactor GP). …

Effects of Reduced Phenolic Acids on Ruminant Hepatic Metabolism
… reduced phenolics inhibited gluconeogenesis from propionate in bovine liver tissue at.4 mM and BA, PPA, and CA inhibited it at.2 mM. Oxidation of palmitate was inhibited by all the reduced phenolics (.2 mM) with 4OHPPA being least inhibitory. The reduced phenolics caused leakage of lactate …

THE EFFECT OF DIETARY FIBRE ON HUMAN LIPID METABOLISM
… effect of soluble fibre may be mediated through propionate, a short chain fatty acid (SCFA) normally produced from the fermentation in the colon. Propionyl-CoA may compete with acetyl-CoA for binding sites on HMG-CoA synthase. Changes in serum glucagon have been reported when SCFA are infused …

SHORT-CHAIN FATTY ACIDS INDUCED AUTOPHAGY SERVES AS AN ADAPTIVE STRATEGY FOR RETARDING MITOCHONDRIA-MEDIATED APOPTOTIC CELL DEATH
… fibers in human large intestine. SCFAs, mostly propionate and butyrate, inhibit proliferation and induce apoptosis in colon cancer cells, but clinical trials had mixed results regarding the anti-tumor activities of SCFAs. Herein we demonstrate that propionate and butyrate induced autophagy in …

Volatile Fatty Acid Production in Ruminants
… errors (RMSPE) were 63, 63, and 49% for acetate, propionate and butyrate, respectively. An assessment from two studies reporting VFA production revealed a potential of reducing errors of prediction by representing interconversion among VFA. In the second study, equations based on thermodynamics …

Oxygen Regulated Genes in Salmonella Typhimurium
… it encodes a 42-kD protein which has acetate/propionate kinase activities. The cloned oxd-2 gene, under a foreign promoter, complemented an ackA (encoding an acetate kinase) mutation. Both Oxd-2 and AckA have a similar substrate range, and Oxd-2 has higher affinity for propionate than for …

Influence of Homeorhetic State on Ruminant Metabolism and Substrate Selection for Hepatic Gluconeogenesis
… glucose demand on conversion of (1-$\sp{14}$C) propionate and (1-$\sp{14}$C) alanine to CO$\sb2$ and glucose. Phlorizin tended to increase conversion of substrates to CO$\sb2.$ Conversion of (1-$\sp{14}$C) alanine to glucose was increased more by phlorizin treatment than that of (1-$\sp{14}$C) …

Roles of the Methylcitrate and Methylmalonyl-COA Pathways in Mycobacterial Metabolism and Pathogenesis
… uses the methylcitrate cycle for growth on propionate. In the absence of the methylcitrate cycle M. smegmatis, in contrast to M. tuberculosis, can eventually endogenously activate the methylmalonyl-CoA pathway in vitro, presumably through B12 synthesis. In mutants of both species, lacking …
