Novel liquid chromatography–mass spectrometry method shows that vitamin E deficiency depletes arachidonic and docosahexaenoic acids in zebrafish (Danio rerio) embryos

open access: yesRedox Biology, 2014
To test the hypothesis that embryogenesis depends upon α-tocopherol (E) to protect embryo polyunsaturated fatty acids (PUFAs) from lipid peroxidation, new methodologies were applied to measure α-tocopherol and fatty acids in extracts from saponified ...

Symmetry Scheme for Amino Acid Codons [PDF]

open access: yesPhys.Rev.E65, 021912 (2002), 2003
Group theoretical concepts are invoked in a specific model to explain how only twenty amino acids occur in nature out of a possible sixty four. The methods we use enable us to justify the occurrence of the recently discovered twenty first amino acid selenocysteine, and also enables us to predict the possible existence of two more, as yet undiscovered ...

Plasma oxylipins and unesterified precursor fatty acids are altered by DHA supplementation in pregnancy: Can they help predict risk of preterm birth? [PDF]

open access: yes, 2019
Oxidized lipids derived from omega-6 (n-6) and omega-3 (n-3) polyunsaturated fatty acids, collectively known as oxylipins, are bioactive signaling molecules that play diverse roles in human health and disease.

Dietary arachidonic acid increases deleterious effects of amyloid-β oligomers on learning abilities and expression of AMPA receptors: putative role of the ACSL4-cPLA2 balance

open access: yesAlzheimer’s Research & Therapy, 2017
Background Polyunsaturated fatty acids play a crucial role in neuronal function, and the modification of these compounds in the brain could have an impact on neurodegenerative diseases such as Alzheimer’s disease.

Inhibition of the Nicotinic Ion Channel by Arachidonic Acid and Other Unsaturated Fatty, Acids in Chromaffin Cells from Bovine Adrenal Medulla

open access: yesCHIMIA, 1991
The effects of arachidonic and other cis-unsaturated fatty acids were investigated in cultured chromaffin cells from bovine adrenal medulla with respect to Ca2+ influx and secretion of catecholamines.

Is the anti-filarial drug diethylcarbamazine useful to treat COVID-19? [PDF]

open access: yesarXiv, 2020
The SARS-CoV-2 virus has resulted in a devastating pandemic of COVID-19. Exploring compounds that could offer a breakthrough in treatment is the need of the hour. Re-positioning cheap, freely available and safe drugs is a priority. The paper proposes evidence for the potential use of diethylcarbamazine (DEC) in the treatment of COVID-19.

Gut Microbiota-derived Bile Acids Promote Gamma-secretase Activity Through Interactions with Nicastrin Subunits [PDF]

open access: yesarXiv, 2023
Alzheimer's disease (AD) has emerged as a progressively pervasive neurodegenerative disorder worldwide. Bile acids, synthesized in the liver and modified by the gut microbiota, play pivotal roles in diverse physiological processes, and their dysregulation in individuals with AD has been well-documented.

Functional Characterization of Mouse and Human Arachidonic Acid Lipoxygenase 15B (ALOX15B) Orthologs and of Their Mutants Exhibiting Humanized and Murinized Reaction Specificities [PDF]

open access: yes, 2023
The arachidonic acid lipoxygenase 15B (ALOX15B) orthologs of men and mice form different reaction products when arachidonic acid is used as the substrate.

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]

open access: yesJournal of the European Ceramic Society, Volume 32, Issue 1, 2012, Pages 235-244, 2013
The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

n-3 polyunsaturated fatty acids, inflammation, and inflammatory diseases.

open access: yesAmerican Journal of Clinical Nutrition, 2006
Inflammation is part of the normal host response to infection and injury. However, excessive or inappropriate inflammation contributes to a range of acute and chronic human diseases and is characterized by the production of inflammatory cytokines ...
