TL;DR: Urinary pyridinium crosslinks of collagen also show great promise as markers of therapeutic efficacy in bone disorders associated with accelerated bone resorption.
Abstract: The hydroxypyridinium compounds pyridinoline and deoxypyridinoline are specific constituents of mature skeletal collagens. They are released into the circulation and excreted in the urine. Their measurement in urine is a sensitive index of the extent of ongoing bone resorption. Currently, quantification of collagen crosslinks in urine is achieved by chromatographic techniques, but more convenient immunoassays will make these measurements more widely available in the near future. Clinical applications of hydroxypyridinium markers include numerous metabolic bone disorders such as osteoporosis, primary hyperparathyroidism, Paget's disease of bone, and metastatic bone disease. Urinary pyridinium crosslinks of collagen also show great promise as markers of therapeutic efficacy in bone disorders associated with accelerated bone resorption.

TL;DR: Sodium fumarate was the preferred propionate precursor for use as a feed ingredient to decrease CH4 emissions from ruminants and caused a stimulation in fibre digestion.
Abstract: Fifteen potential precursors of propionate were tested for their ability to decrease CH4 production by ruminal fluid in vitro. Sodium acrylate and sodium fumarate produced the most consistent effects in batch cultures, with 50 % of the added precursors being fermented to propionate and CH4 production decreasing by between 8 and 17 %, respectively. Additives were more effective when added as free acids, but this also decreased the pH and may have inhibited fibre digestion. Changing the dietary substrate from predominantly grass hay to predominantly concentrate had no influence on the effectiveness of acrylate and fumarate. In an in vitro fermentor (the rumen simulating technique, Rusitec) with a grass hay-concentrate (50:50, w/w) diet as substrate, both compounds were again fermented to propionate (33 and 44 % conversion to propionate, respectively). However, fumarate appeared more effective as a H2 sink compound. It was calculated to capture 44 % of the H2 previously used for CH4 formation compared with a 22 % capture of H2 with acrylate. Fumarate also caused a stimulation in fibre digestion. Thus, sodium fumarate was the preferred propionate precursor for use as a feed ingredient to decrease CH4 emissions from ruminants.

TL;DR: A gas chromatography/mass spectrometry method for measuring very low levels of enrichment of d5-phenylalanine (0.002-0.09 atom percent excess) makes it possible to determine the enrichment of amino acid incorporated into tissue protein during studies of protein synthesis in man.
Abstract: A gas chromatography/mass spectrometry (GC/MS) method for measuring very low levels of enrichment of d5-phenylalanine (0.002-0.09 atom percent excess) is described. This method makes it possible to determine the enrichment of amino acid incorporated into tissue protein during studies of protein synthesis in man. Phenylalanine is enzymatically converted to phenylethylamine and the d5-enrichment is measured in the heptafluorobutyryl derivative by selective-ion recording under electron ionization conditions. The coefficients of variation for muscle-protein hydrolysate samples enriched with d5-phenylalanine at the 0.005 and 0.05 atom percent excess levels were 6.0 and 1.2%, respectively. This precision at low enrichment and the small amount of protein needed (about 1 mg) provide real advantages for clinical studies of tissue protein synthesis. Moreover, in contrast to the conventional approach which uses GC/MS for plasma amino acids (typically 2-20 atom percent excess) but gas isotope-ratio mass spectrometry for protein-bound amino acids, the enrichment of both plasma-free and protein-bound d5-phenylalanine can be measured with a single instrument.

TL;DR: Investigation in term placentae from normal pregnancies found a mechanism to allow the preferential transfer of docosahexaenoic acid and the essential fatty acids to the fetal circulation, thereby protecting the polyunsaturated fatty acid supply to the fetus during a critical period of development.

TL;DR: It was found that the effects of the steroidal saponins in Yucca schidigera extract (YE) on ruminal microbial activity and saponin degradation, but did not affect DMD or bacterial activity, and did not induce resistance to YE at a concentration of 5 mg ml −1 .
