The chemical profiles of vaginal fluid collected from cows in oestrus and nonoestrus were analysed by gas chromatography-mass spectrometry (GC-MS) to establish any qualitative differences that might have potential value in bovine biocommunication. Eight different organic compounds were detected using the two chromatograms. The chemical profiles of oestrus vaginal fluid were distinguished signif...

Circulating trimethylamine-N-oxide (TMAO) levels are strongly associated with atherosclerosis. We now examine genetic, dietary, and hormonal factors regulating TMAO levels. We demonstrate that two flavin mono-oxygenase family members, FMO1 and FMO3, oxidize trimethylamine (TMA), derived from gut flora metabolism of choline, to TMAO. Further, we show that FMO3 exhibits 10-fold higher specific ac...

A preterm baby boy with blood and bone changes of copper deficiency is described. Copper deficiency was suspected after fracture of the left femur during examination of the hip joint. A low serum copper concentration (2.7 mumol/l; 17.2 micrograms/100 ml) and caeruloplasmin (0.04 g/l; 0.004 g/100 ml) confirmed the diagnosis. Despite the introduction of solids at 18 weeks the copper concentration...

Hyperglycaemia impairs recovery from transient cerebral ischaemia: the importance of tissue acidification for this phenomenon has not been clarified in detail. We investigated this issue in a less complex in vitro preparation of isolated rat dorsal spinal roots exposed for 30 min to hyperglycaemic hypoxia. Peak height of compound action potentials recovered minimally in 5 mM bicarbonate. Howeve...

This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg(-1) phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg(-1) feed additive whereas egg production, ...

COHEN, JULIUS J., MARCUS A. KRUPP, CHARLES A. CHIDSEY III AND CHARLES I. BILTZ. Effect of trimethylamine and its homologues on renal conservation of brimethylamine oxide by the spiny dogjsh, Squalus acanthias, Am. J. Physiol. I g6( I): 93-99 I g5g.-In renal clearance experiments with dogfish, trimethylamine HCL (TMA) d a ministration (i.m.) results in a large increase in trimethylamine oxide (O...

The composition of the gaseous phases during pyrolytic laser-induced chemical vapor deposition (LCVD) of aluminium from triisobutylaluminium (TIBA) and trimethylamine alane (TMAA) (aluminium trihydride trimethylamine) was determined. The analysis was carried out by means of quadrupole mass spectrometer (QMS) in closed reaction cell. The developed arrangement for sampling allowed in situ analyse...

The major inducible trimethylamine oxide reductase was purified from Salmonella typhimurium LT2. The molecular weights of the native enzyme were estimated to be 332,000 by gel filtration and 170,000 by nondenaturing disc gel electrophoresis. In sodium dodecyl sulfate-gel electrophoresis, the enzyme formed a single band of molecular weight 84,000. The isoelectric point was 4.28. Maximum activity...

The outcome of neutral and photoionized N~CH3!2 primary products of trimethylamine photodissociation at 193 nm is determined by combining photoionization detection with supporting G3 theoretical calculations. N~CH3!2 primary products with very little internal energy show an experimentally observed ionization onset of 9.160.2 eV, but do not appear at the parent ion (m/e544). Instead, the parent ...

The extractive constituents, which are known as taste active components of fisheries products in many research works have been reviewed..This review found glutamate, glycine, alanine, arginine, proline, valine, methionine, phenylalanine, tyrosine, inosine 5’-monophosphate (IMP), adenosine 5’monophosphate (AMP), guanosine 5’-monophosphate (GMP), trimethylamine, trimethylamine oxide (TMAO), glyci...
