Symmetry Scheme for Amino Acid Codons [PDF]

Phys.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 ...

The impact of 60 days of ‐6° head down tilt bed rest on mitochondrial content, respiration and regulators of mitochondrial dynamics

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Reductions in skeletal muscle mitochondrial respiration following 60 days of bed rest explained by a decrease in mitochondrial content, but resulting in an increase in OPA1 and Drp1 mediated mitochondrial fission. Abstract It is unclear how skeletal muscle metabolism and mitochondrial function adapt to long duration bed rest and ...

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

arXiv, 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.

Researches on the Pharmacological Effects of Eicosapentaenoic Acid [PDF]

American Journal of Medicine Studies, 2015
Fish oils are the most common source of omega-3 polyunsaturated fatty acids (n-3 PUFAs), mainly eicosapentaenoic acid(EPA). It has been pointed out protective effects and beneficial effects of EPA on body weight reduction, heart health, blood lipid profile, cardiovascular diseases and other diseases.

Omega‐3 Polyunsaturated Fatty Acids Intake and Blood Pressure: A Dose‐Response Meta‐Analysis of Randomized Controlled Trials

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Current evidence might support the use of omega‐3 fatty acids (preferably docosahexaenoic acid and eicosapentaenoic acid) for lowering blood pressure (BP), but the strength and shape of the dose‐response relationship remains unclear.

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

Journal 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.

Effects of eicosapentaenoic acid and docosahexaenoic acid on lipoproteins in hypertriglyceridemia [PDF]

Current Opinion in Endocrinology, Diabetes & Obesity, 2016
The treatment of hypertriglyceridemia (HTG) with ω-3 fatty acid preparations adds a novel therapy to reduce cardiovascular disease. This review examines the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid on lipoproteins and the cardioprotective effects in HTG.The evidence that ω-3 fatty acid therapy at prescription strength is ...

Fatty Acid Taste Receptor GPR120 Activation by Arachidonic Acid, Eicosapentaenoic Acid, and Docosahexaenoic Acid in Chickens

The Journal of Poultry Science, 2022
It has been reported that the supplementation of chicken diet with polyunsaturated fatty acids (PUFAs) such as arachidonic acid (AA), eicosapentaenoic acid (EPA), or docosahexaenoic acid (DHA) affects the qualities of eggs and meat.

Altering 15‐Lipoxygenases to 18‐Lipoxygenases and Their Application to the Production of 5,18‐Dihydroxyeicosapentaenoic Acids

Biotechnology and Bioengineering, EarlyView.
15R‐ and 15S‐lipoxygenases (15R‐ and 15S‐LOXs) were engineered into 18R‐ and 18S‐LOXs, respectively. Escherichia coli expressing these enzymes converted eicosapentaenoic acid into 18R‐ and 18S‐hydroxyeicosapentaenoic acids (18R‐ and 18S‐HEPEs), respectively.

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]

, 2014
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.
