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 ...

Gamma-aminobutyric acid and probiotics: Multiple health benefits and their future in the global functional food and nutraceuticals market

Journal of Functional Foods, 2020
Probiotics have attracted growing interest in recent decades due to their multiple health benefits. The synergistic relationship between probiotics and prebiotics can enhance the production of metabolites called postbiotics, which are gaining increasing ...

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.

Effects of ethylenediamine – a putative GABA-releasing agent – on rat hippocampal slices and neocortical activity in vivo [PDF]

, 2010
The simple diamine diaminoethane (ethylenediamine, EDA) has been shown to activate GABA receptors in the central and peripheral nervous systems, partly by a direct action and partly by releasing endogenous GABA.

Calcium Imaging Reveals Coordinated Simple Spike Pauses in Populations of Cerebellar Purkinje Cells

Cell Reports, 2016
The brain’s control of movement is thought to involve coordinated activity between cerebellar Purkinje cells. The results reported here demonstrate that somatic Ca2+ imaging is a faithful reporter of Na+-dependent “simple spike” pauses and enables us to ...

Coordination of opposing sex-specific and core muscle groups regulates male tail posture during Caenorhabditis elegans male mating behavior [PDF]

, 2009
Background To survive and reproduce, animals must be able to modify their motor behavior in response to changes in the environment. We studied a complex behavior of Caenorhabditis elegans, male mating behavior, which provided a model for understanding ...

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.

Learning the Hydrophilic, Hydrophobic and Aromatic Character of Amino Acids from their Interfacial Thermal Conductance in Water [PDF]

, 2021
In this study, the thermal relaxation of the 20 naturally occurring amino-acids in water is investigated using transient non-equilibrium molecular-dynamics simulations. By modeling the thermal relaxation process, the relaxation times of the amino-acids in water occurs over a timescale covering 2-5 ps.

Characterization of biodegradable food packaging films prepared with polyamide 4: Influence of molecular weight and environmental humidity

Food Bioengineering, Volume 1, Issue 3-4, Page 276-288, December 2022., 2022
Colorless and translucent polyamide 4 (PA4) films, which are both bio‐based and biodegradable, were prepared by the solution casting method in a dual‐solvent system. The physical properties of single PA4 films were originally characterized, and the effects of molecular weight and environmental humidity on PA4 were investigated. Abstract The development

The Role of GABA and Insulin Regulated Aminopeptidase on Insulin Resistance and GLUT4 in Prediabetes and Type 2 Diabetes Mellitus

مجله كليه طب الكندي
Background: Different proposed mechanisms for insulin resistance have been put forth to understand the relationship and changes in insulin resistance. Looking at the levels of insulin, the neurotransmitter gamma-aminobutyric acid, glucose transport type
