Arachidonic Acid Stress Impacts Pneumococcal Fatty Acid Homeostasis

open access: yesFrontiers in Microbiology, 2018
Free fatty acids hold dual roles during infection, serving to modulate the host immune response while also functioning directly as antimicrobials. Of particular importance are the long chain polyunsaturated fatty acids, which are not commonly found in ...

Acid zeta function and ajoint acid zeta function [PDF]

open access: yesarXiv, 2010
In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Characterization of the pattern of development of key compounds contributing to aroma quality of chicken meat and their metabolic markers

open access: yesAnimal Research and One Health, EarlyView.
The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.

Peroxisome Proliferators Attenuate Free Arachidonic Acid Pool in the Kidney Through Inducing Lysophospholipid Acyltransferases

open access: yesJournal of Pharmacological Sciences, 2009
Attenuating effects of peroxisome proliferators on the concentration of free arachidonic acid by inducing 1-acyl-2-lysophospholipid acyltransferases in the kidney were studied.

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]

open access: yesarXiv, 1999
Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

open access: yesAnimal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

open access: yesarXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

The Factors of the Classification of Protein Amino Acids [PDF]

open access: yesThis paper is published in GLASNIK of Montenegrin Academy of Science and arts, 2000, 13, pp. 173-194, 2006
In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

Arachidonic acid in cellular activation [PDF]

open access: yesKidney International, 1999
The paper by Huang et al in this issue of Kidney International addresses the interesting and still unsettled question as to whether arachidonic acid (AA), in and of itself, is a specific pathophysiologic "mediator" of injury, independently of its further transformation into oxygenated derivatives1.

Efficient One‐Step Production of 7S,17S‐ and 10S,17S‐Dihydroxydocosahexaenoic Acids by a Double‐Oxygenating 15S‐Lipoxygenase From Chlamydomonas incerta

open access: yesBiotechnology and Bioengineering, EarlyView.
Biotransformation pathway from polyunsaturated fatty acids into dihydroxy fatty acids as lipid mediators by Escherichia coli expressing Chlamydomonas incerta 15S‐lipoxygenase with double oxygenating activity. The 15S‐lipoxygenase was the most efficient for the simultaneous production of resolvin D5 (7S,17S‐dihydroxydocosahexaenoic acid, 7S,17S‐DiHDHA ...
