African dung beetle Onthophagus gazella Fabricius (Coleoptera: Scarabaeidae) esterase isozymes

Brazilian Journal of Biology
African beetles Onthophagus gazella from both sexes were analyzed by electrophoresis for an investigation of esterase isozymes using alpha-naphthyl propionate and methylumbelliferyl propionate as substrates. Only one of the esterases (Est.

Hypothalamic Astrocytes Exhibit Glycolytic Features Making Them Prone for Glucose Sensing

Glia, EarlyView.
Hypothalamic astrocytes versus cortical astrocytes: are more glycolytic due to high Pkm2, Glut1 and Mct4 expression do not exhibit glutamate‐induced glycolysis detect glucose concentration variations via an AMPK sensor with altered lactate production. ABSTRACT In the hypothalamus, detection of energy substrates such as glucose is essential to regulate ...

Biallelic ELOVL1 Variants Are Linked to Hypomyelinating Leukodystrophy, Movement Disorder, and Ichthyosis

Movement Disorders, EarlyView.
Abstract Background Very long chain fatty acids (VLCFAs) are an integral component of myelin and the epidermal water barrier. Variants in genes encoding enzymes responsible for catalyzing the first and rate limiting step in the production of VLCFAs, elongation of VLCFAs (ELOVLs), underlie a novel group of metabolic disorders. Objectives The goal was to

Variability among inbred lines and RFLP mapping of sunflower isozymes

Genetics and Molecular Biology, 2002
Eight isozyme systems were used in this study: acid phosphatase (ACP), alcohol dehydrogenase (ADH), esterase (EST), glutamate dehydrogenase (GDH), malate dehydrogenase (MDH), phosphoglucoisomerase (PGI), 6-phosphogluconate dehydrogenase (PGD), and ...

Design, Synthesis, Biological Evaluation, and In Silico Study of Tetrahydropyridines as Prospective Monoamine Oxidase Inhibitors

ChemistryOpen, EarlyView.
This work investigates the selective inhibition of MAO enzymes by varying the substitution of electron‐withdrawing and donating groups on the phenyl rings of tetrahydropyridines (4 a–4 o). Compounds 4 l and 4 n exhibit promising IC50 values of 0.40±0.05 and 1.01±0.03 μM against MAO‐A and MAO‐B, respectively.

How do eyespot resistance genes transferred into winter wheat breeding lines affect their yield?

Journal of Plant Protection Research, 2016
Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez;

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Genetic diversity and population structure of pedunculate oaks (Quercus robur) in Wytham Woods

PLANTS, PEOPLE, PLANET, EarlyView.
Genetic diversity underpins forest resilience and adaptation, yet centuries of human activity have reshaped woodland ecosystems worldwide. We studied the population genetics of pedunculate oaks (Quercus robur) in Wytham Woods, UK, across stands with different ages and management histories.
