Arachidonic Acid Stress Impacts Pneumococcal Fatty Acid Homeostasis
Frontiers 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]
arXiv, 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.

Animal 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.

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

Animal 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]
arXiv, 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]
This 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]
Kidney 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.

Biotechnology 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 ...
