Interaction between myeloperoxidase and mixtures of lecithin-cholesterol monolayers were investigated. Solubility of the enzyme in 1-octanol or in octanol were tested too. It is shown that myeloperoxidase demonstrates an ability to concentrate on phase limits. The enzyme well dissolves in lipid membrane phases. It is possible to assume that myeloperoxidase penetrates and accumulates in the eye lens.

GRAS, termed after gibberellic acid insensitive (GAI), RGA (repressor of GA1), and SCR (scarecrow), is a plant-specific transcription factor crucial for plant development and stress response. However, understanding of the functions played by the GRAS members and their target genes in citrus is limited. In this study, we identified a cold stress-responsive GRAS gene from , designated as PtrPAT1, by yeast one-hybrid library screening using the promoter of , a betaine aldehyde dehydrogenase (BADH)-like gene.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.

Mercury (II) ion (Hg) as highly toxic heavy metal may be accumulated in aquatic ecosystems and animals species so as to enter human body to conduct health harm. To ensure the safety of fishes food, hence, it is of great interest to evaluate the Hg levels in different kinds of fishes as well as Hg removal in aquaculture tailwater. In this article, a selective colormetric detection and efficient removal strategy has been developed for Hg ions by the controlled supermolecular self-assembly of melamine (MA)-platinum (Pt) composites onto mesoporous FeO carriers.

Introduction: Gut microbiota alterations have been implicated in Autism Spectrum Disorder (ASD), yet the mechanisms linking these changes to ASD pathophysiology remain unclear.

Objectives: This study utilized a multi-omics approach to uncover mechanisms linking gut microbiota to ASD by examining microbial diversity, bacterial metaproteins, associated metabolic pathways and host proteome.

Methods: The gut microbiota of 30 children with severe ASD and 30 healthy controls was analyzed.

Background: Lead (Pb) could be toxic to the female reproductive system, and resveratrol (Res) may overcome this toxicity.

Objective: To investigate the Res impact on the catalase (), glutathione peroxidase (), and superoxide dismutase () gene expression in the ovary and on the Cat and Gpx enzyme activity in the serum of rats exposed to lead acetate.

Materials And Methods: In this experimental study, 33 female Wistar rats (8-10 wk, 180-200 gr) were divided into 6 groups: a control group (normal saline), a Res group (40 mg/kg), and a Pb group (lead acetate 30 mg/kg).
