Nanoplastics Enhance Transmembrane Transport and Uptake of Carcinogens: Transcriptional Changes and the Effects of Weathering

open access: yesAdvanced Science, EarlyView.
Nanoplastics exposed to defined weathering conditions are systematically investigated as vectors for polycyclic aromatic hydrocarbons (PAHs). This investigation demonstrates significant potential for enhancing PAH uptake and transport in an intestinal membrane model.

Age characteristics of changes in invertase activity of the mucous membrane of the small intestine [PDF]

open access: yes
Rats of varying ages were subjected to stress from heat, cold, and hydrocortisone injection. Invertase activity in homogenates of small intestine mucous membranes was studied following sacrifice. Invertase activity was low in young animals, but increased

Zinc Alleviates Gut Barrier Dysfunction by Promoting the Methylation of AKT

open access: yesAdvanced Science, EarlyView.
Zinc activates the ZNG1‐METAP1 complex to elevate intracellular SAM levels, which promotes PRMT5‐mediated symmetrical dimethylation of AKT at R391 and R15. This epigenetic modification facilitates AKT membrane translocation and mTORC2 activation, thereby enhancing epithelial proliferation and gut barrier integrity.

Hologenomics Reveals Specialized Dietary Adaptations in the Mengla Snail‐Eating Snake

open access: yesAdvanced Science, EarlyView.
Dietary adaptation studies from a holobiome perspective are scarce beyond mammals. This research reveals how genomic and microbial interactions drive dietary specialization in the Mengla snail‐eating snake, with evidence of gut symbiont convergence between reptiles and mammals.

A Combined Aptamer Pulldown‐DNAzyme Cleavage Assay for Intact Methicillin Resistant Staphylococcus aureus Cells

open access: yesAngewandte Chemie, EarlyView.
Rapid fluorescence and lateral flow assays were developed for methicillin resistant Staphylococcus aureus (SA) by combining a DNA aptamer for selective isolation and an RNA‐cleaving DNAzyme for detection of MRSA. Abstract Accurate and convenient detection of methicillin resistant Staphylococcus aureus (MRSA) plays a vital role in determining ...

Lung‐Penetrating Biomimetic Extracellular Vesicle Spherical Nucleic Acids for Pulmonary Fibrosis Therapy Through ROS Scavenging and Anti‐Inflammatory Effects

open access: yesAggregate, EarlyView.
This work describes a biomimetic extracellular vesicle‐spherical nucleic acid (BEV‐SNA) platform for idiopathic pulmonary fibrosis (IPF) therapy. BEV‐SNA is composed of mechanically extruded BEVs from primary MSCs and cholesterol‐modified ssDNA that are assembled through hydrophobic interactions.

RESEARCHES CONCERNING THE HISTOCHEMISTRY AND MICROBIAL FLORA OF THE PUERPERAL UTERUS IN COWS [PDF]

open access: yesJournal of Central European Agriculture, 2002
The microbial population represents a group of heterogeneous germs comprising several different species which live and act together in the same place. The communities of micro-organisms, as independent population groups, are better adapted for growing ...
