A Microgel Platform Enables Site‐Specific Intestinal Delivery of Lactoferrin, Improving its Bioavailability for Targeted Alleviating Liver Injury and Colitis

Advanced Science, EarlyView.
This work first time reports an eco‐friendly desert plant food‐based polysaccharide ASKP microgels which have intestinal site‐specific release properties which can achieve small‐intestine or colon targeting capability via different cross‐linking chemistry.

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Effect of Lactulose on the Intestinal Flora of Elderly Constipation Patients With Chronic Renal Insufficiency

AGING MEDICINE, EarlyView.
This study investigates the regulatory effects of lactulose and polyethylene glycol (PEG) on the composition of gut microbiota in elderly constipation patients with chronic renal insufficiency by comparing the changes in microbial abundance. Both lactulose and PEG significantly modulate the gut microbiota structure, though their specific mechanisms and

Stepwise evolution of the Sec machinery in Proteobacteria [PDF]

Trends in Microbiology, 2006
The Sec machinery facilitates the translocation of proteins across and into biological membranes. In several of the Proteobacteria, this machinery contains accessory features that are not present in any other bacterial division. The genomic distribution of these features in the context of bacterial phylogeny suggests that the Sec machinery has evolved ...

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

American Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

The origin of aerobic methanotrophy within the Proteobacteria [PDF]

FEMS Microbiology Letters, 2019
ABSTRACTAerobic methanotrophs play critical roles in the global carbon cycle, but despite their environmental ubiquity, they are phylogenetically restricted. Via bioinformatic analyses, it is shown that methanotrophy likely arose from methylotrophy from the lateral gene transfer of either of the two known forms of methane monooxygenase (particulate and
