Abstract This experiment evaluated the effects of multiple bovine appeasing substance administration during a 42-day preconditioning program followed by feedlot receiving period on productivity, health, and physiological variables feeder cattle. Ninety recently weaned calves were obtained from Red Bluff Ranch (Norris, MT). All weighed (prior to transport). Calves loaded into livestock trailer, ...

A number of nonamino organic acids associated with inborn errors of metabolism can be detected by gas chromatography. The organic acids are extracted into ethyl acetate and diethyl ether, the extracts combined, and the solvents evaporated under nitrogen. The residue is taken up in carbon disulfide and an aliquot chromatographed on 5% neopentyl glycol adipate to separate short-chain fatty acids ...

Background: Human linkage and animal QTL studies have indicated the contribution of genes on Chr17 into blood pressure regulation. One candidate gene is PNMT, coding for phenylethanolamine-N-methyltransferase, catalyzing the synthesis of epinephrine from norepinephrine. Methods: Fine-scale variation of PNMT was screened by resequencing hypertensive (n = 50) and normotensive (n = 50) individuals...

Glucose- and temperature-sensitive polymers of a phenylboronic acid derivative and diethylene glycol dimethacrylate (poly(3-acrylamidophenyl boronic acid-b-diethylene glycol methyl ether methacrylate); p(AAPBA-b-DEGMA)) were prepared by reversible addition-fragmentation chain transfer polymerization. Successful polymerization was evidenced by 1H nuclear magnetic resonance and infrared spectrosc...

Biodegradation is generally recognised as an important removal mechanism for pollutants in natural ecosystems. It determines the concentration of substances in the environment. According to the legislation of the European Union, there are three levels for biodegradability testing protocols for chemicals which cover different test conditions. This paper describes one such multilevel approach to ...

Epithelial injury contributes to pathogenesis in idiopathic pulmonary fibrosis (IPF) but its role in the interstitial lung disease (ILD) of systemic sclerosis (SSc) is uncertain. We quantified the prognostic significance of inhaled technetium-99m ((99m)Tc)-labelled diethylene triamine pentacetate (DTPA) pulmonary clearance, a marker of the extent of epithelial injury, in both diseases. Baseline...
