Medium alkalization due to carbon metabolism is largely responsible for inhibition of bacterial growth by Vibrio cholerae supernatants [PDF]

open access: yes, 2017
Vibrio cholerae is the causative agent of the diarrheal disease cholera. Many Vibrio species secrete antimicrobial factors, though the identity of such a factor has not been determined for any V. cholerae strain.

Effect of genotype on duodenal expression of nutrient transporter genes in dairy cows [PDF]

open access: yes, 2013
peer-reviewedBackground Studies have shown clear differences between dairy breeds in their feed intake and production efficiencies. The duodenum is critical in the coordination of digestion and absorption of nutrients.

Localization and Functional Relevance of System A Neutral Amino Acid Transporters in Cultured Hippocampal Neurons [PDF]

open access: yesJournal of Biological Chemistry, 2002
Glutamine and alanine are important precursors for the synthesis of glutamate. Provided to neurons by neighboring astrocytes, these amino acids are internalized by classical system A amino acid carriers. In particular, System A transporter (SAT1) is a highly efficient glutamine transporter, whereas SAT2 exhibits broad specificity for neutral amino ...

Nature of the Cosubstrate Action of Na+ and Neutral Amino Acids in a Transport System

open access: yesJournal of Biological Chemistry, 1971
Abstract We have studied in the rabbit reticulocyte and the pigeon erythrocyte the interactions between Na+ and various neutral amino acids with respect to transport by an apparently ubiquitous Na+-dependent system that prefers the linear aliphatic and hydroxy aliphatic amino acids.

Heat Stress and feeding strategies in meat-type chickens [PDF]

open access: yes, 2011
Heat stress can induce hyperthermia in poultry. A reduction in heat load can be achieved by increasing the possibilities for dissipation, decreasing the level of heat production or by changing the thermal production pattern within a day.

Biological hot spots and the accumulation of marine dissolved organic matter in a highly productive ocean margin [PDF]

open access: yes, 2016
Concentrations of dissolved organic carbon (DOC) and major biochemicals (amino acids and carbohydrates) were measured during five cruises (2009–2010) to the Louisiana margin in the northern Gulf of Mexico.

Neutral amino acid transport systems of tissue culture cells.

open access: yesJournal of Biological Chemistry, 1977
We have studied the interactions among a varied group of neutral amino acids for uptake into two different animal tissue culture cell lines. 3T3 mouse cells and Chinese hamster ovary cells were used in these studies. The results showed that the affinities of the amino acids clustered into two groups, one including amino acids such as glycine, alanine ...

Effect of charged lipids on the ionization behavior of glutamic acid containing transmembrane helices [PDF]

open access: yes, 2020
Transmembrane proteins make up critical components of living cells. Protein function can be greatly impacted by the charged state of its respective components, the side chains of amino acid residues.

Pharmacometabolomic mapping of early biochemical changes induced by sertraline and placebo. [PDF]

open access: yes, 2013
In this study, we characterized early biochemical changes associated with sertraline and placebo administration and changes associated with a reduction in depressive symptoms in patients with major depressive disorder (MDD).
