Quantitative Detection of Syntrophic Fatty Acid-degrading Bacterial Communities in Methanogenic Environments [PDF]

open access: yes, 2015
In methanogenic habitats, volatile fatty acids (VFA), such as propionate and butyrate, are major intermediates in organic matter degradation. VFA are further metabolized to H2, acetate and CO2 by syntrophic fatty acid-degrading bacteria (SFAB) in ...

Inhaled corticosteroids versus long-acting beta -agonists for chronic obstructive pulmonary disease (Review). [PDF]

open access: yes, 2011
Long-acting beta(2)-agonists and inhaled corticosteroids can be used as maintenance therapy by patients with moderate to severe chronic obstructive pulmonary disease. These interventions are often taken together in a combination inhaler.

Role of gut microbiota-generated short chain fatty acids in metabolic and cardiovascular health [PDF]

open access: yes, 2018
Purpose of this Review: This review assesses the latest evidence linking short-chain fatty acids (SCFA) with host metabolic health and cardiovascular disease (CVD) risk and presents the latest evidence on possible biological mechanisms.

Determination of the degree of substitution (DS) of mixed cellulose esters by elemental analysis [PDF]

open access: yes, 2001
Equations for transforming the results of elemental analysis (EA) into degree of substitution (DS) values for aliphatic cellulose esters were developed.

Genomic reconstruction of short-chain fatty acid production by the human gut microbiota

open access: yesFrontiers in Molecular Biosciences, 2022
Short-chain fatty acids (SCFAs) including acetate, formate, propionate, and butyrate are the end products of dietary fiber and host glycan fermentation by the human gut microbiota (HGM).

Lactate-proton co-transport and its contribution to interstitial acidification during hypoxia in isolated rat spinal roots [PDF]

open access: yes, 1993
Exposure of nervous tissue to hypoxia results in interstitial acidification. There is evidence for concomitant decrease in extracellular pH to the increase in tissue lactate.

Resonance Raman Interrogation of the Consequences of Heme Rotational Disorder in Myoglobin and its Ligated Derivatives [PDF]

open access: yes, 2008
Resonance Raman spectroscopy is employed to characterize heme site structural changes arising from conformational heterogeneity in deoxyMb and ligated derivatives, i.e., the ferrous CO (MbCO) and ferric cyanide (MbCN) complexes.

Enhanced product recovery from glycerol fermentation into 3-carbon compounds in a bioelectrochemical system combined with in situ extraction

open access: yesFrontiers in Bioengineering and Biotechnology, 2016
Given the large amount of crude glycerol formed as a by-product in the biodiesel industries and the concomitant decrease in its overall market price, there is a need to add extra value to this biorefinery side stream.

Narasin inclusion for feedlot lambs fed a diet containing high amounts of ground flint corn

open access: yesScientia Agricola, 2020
: Narasin is an antibacterial agent that may change rumen fermentation. Two experiments were proposed to evaluate the efficiency of narasin inclusion for lambs fed a diet containing high amounts of ground flint corn.
