Allosteric modulation of retinal GABA receptors by ascorbic acid [PDF]

, 2011
Ionotropic GABA receptors (GABAA and GABAC) belong to the Cys-loop receptor family of ligand-gated ion channels. GABAC receptors are highly expressed in the retina, mainly localized at the axon terminals of bipolar cells.

Nutritional and industrial quality assessment of Spanish durum wheat commercial cultivars

Journal of the Science of Food and Agriculture, Volume 105, Issue 12, Page 6839-6849, September 2025.
Abstract BACKGROUND Durum wheat is the raw material used to produce pasta, and its price is determined by grain physical characteristics, gluten strength and semolina yellowness. Gluten strength is mainly determined by high‐ and low‐molecular‐weight glutenin subunits (HMW‐GS and LMW‐GS). Semolina yellowness is determined by loci that control carotenoid

A Recursive Model Approach to Include Epigenetic Effects in Genetic Evaluations Using Simulated DNA Methylation Effects

Journal of Animal Breeding and Genetics, Volume 142, Issue 5, Page 550-559, September 2025.
ABSTRACT The advancement of epigenetics has highlighted DNA methylation as an intermediate‐omic influencing gene regulation and phenotypic expression. With emerging technologies enabling the large‐scale and affordable capture of methylation data, there is growing interest in integrating this information into genetic evaluation models for animal ...

Application of Neesler reagent in the ammonium quantification used in the fermentations of biotechnology products

VacciMonitor, 2015
The ammonium salts are used in fermentations to supplement the deficient amounts of nitrogen and stabilize the pH of the culture medium. The excess ammonium ion exerts a detrimental effect on the fermentation process inhibiting microbial growth.

Enhancer turnover and conserved regulatory function in vertebrate evolution [PDF]

, 2013
Mutations in regulatory regions including enhancers are an important source of variation and innovation during evolution. Enhancers can evolve by changes in the sequence, arrangement and repertoire of transcription factor binding sites, but whole ...

Accessory Chromosome Contributes to Virulence of Banana Infecting Fusarium oxysporum Tropical Race 4

Molecular Plant Pathology, Volume 26, Issue 9, September 2025.
The independent accessory chromosome 12 (AC12) is dispensable for vegetative growth but contributes significantly to the virulence of banana‐infecting Fusarium oxysporum Tropical Race 4. ABSTRACT Filamentous fungi have evolved compartmentalised genomes comprising conserved core regions and dynamic accessory regions, which are thought to drive ...
