Activities of oxygen-dependent thiol: O2 oxidoreductase (EC 1.8.3.2) and glutathione-dependent thiol: protein-disulfide oxidoreductase (EC 1.8.4.2) as well as technological value of seven soft spring wheat cultivars grown on different soil under contrasting climatic conditions (Krasnodar krai and Irkutsk oblast) were studied. It was found that the ratio of these enzymatic activities correlated positively with dough physical properties and flour bread-baking quality.

Background: In recent decades, epidemiological and experimental studies have looked into the role of pesticides, particularly the herbicide paraquat, in the development of Parkinson's disease. Horseradish tree (Moringa oleifera) is an ethnobotanical plant with lots of therapeutic potential, but there is a dearth of information on the bioactive properties of the seed alkaloid extracts.
Method: This study examined the modulatory effects of various concentrations of an alkaloid extract from the seeds of Horseradish Tree (Moringa oleifera) on the survival rate of flies exposed to paraquat, as well as certain biochemical and molecular markers related to Parkinson's disease in the heads of the flies.

Background: Lysyl oxidase-like 2 (LOXL2) is a metalloenzyme that catalyzes oxidative deamination ε-amino group of lysine. It has been found that LOXL2 is a promotor for the metastasis and invasion in kinds of tumors. Previous studies show that disulfide bonds are important components in LOXL2, and their bioactivity can be regulated by those bonds.

Hexabromocyclododecane (HBCD) poses significant environmental risks, and identifying HBCD-degrading microbes and their enzymatic mechanisms is challenging due to the complexity of microbial interactions and metabolic pathways. This study aimed to identify critical genes involved in HBCD biodegradation through two approaches: functional annotation of metagenomes and the interpretation of machine learning-based prediction models. Our functional analysis revealed a rich metabolic potential in Chiang Chun soil (CCS) metagenomes, particularly in carbohydrate metabolism.

Novel and simple spectrophotometric and distance based procedures for thiols (L-cysteine, N-acetylcysteine, and glutathione) determination in biological fluids and pharmaceuticals have been proposed based on their inhibitory action on the oxidation of catechol in the presence of Agaricus bisporus crude extract (ABE). The influence of L-glycine, L-alanine, L-proline, L-methionine, L-cystine, ascorbic acid, uric acid, and bilirubin on the thiol determination has been investigated. Uric acid, bilirubin, L-cystine (oxidized thiol), and L-amino acids do not interfere with the determination.

Quercetin is a natural flavonoid and one of the most powerful antioxidants. Due to its wide range of biological properties, it may improve cognitive and physical performance by affecting nervous tissue. The current study is aimed at determining the effect of prenatal exposure to quercetin against methimazole (MMI)-induced hypothyroidism on reflexive motor behavior in mouse offspring.
