The Multifaceted Activity of the VirF Regulatory Protein in the Shigella Lifestyle [PDF]

, 2016
Shigella is a highly adapted human pathogen, mainly found in the developing world and causing a severe enteric syndrome. The highly sophisticated infectious strategy of Shigella banks on the capacity to invade the intestinal epithelial barrier and cause ...

Metabolic changes during cardiac regeneration in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Spermidine promotes Bacillus subtilis biofilm formation by activating expression of the matrix regulator slrR [PDF]

, 2017
Ubiquitous polyamine spermidine is not required for normal planktonic growth of Bacillus subtilis but is essential for robust biofilm formation. However, the structural features of spermidine required for B.

The Carbon Number‐specific Impact of Mineral Oil Saturated Hydrocarbons on Inducing Colonic Inflammation in Female and Male Fischer 344 Rats

Food Frontiers, EarlyView.
MOSH‐induced colonic alterations and sex‐specific metabolic pathways in female and male F344 rats. ABSTRACT This study investigated the effects of mineral oil saturated hydrocarbon (MOSH) sub‐fractions (C20‐30 and C30‐50) on the colon of male and female F344 rats and the underlying mechanisms.

A liquid crystalline phase in spermidine-condensed DNA [PDF]

, 1994
Over a large range of salt and spermidine concentrations, short DNA fragments precipitated by spermidine (a polyamine) sediment in a pellet from a dilute isotropic supernatant.

Protective Effects of Potential Probiotic Pediococcus acidilactici 100 Against Multi‐Drug‐Resistant Diarrheal Escherichia coli Strains Induced Changes in Caenorhabditis elegans Model System

Food Safety and Health, EarlyView.
This study shows the protective effects of potential probiotic strain of Pediococci strains against diarrheal Escherichia coli strains in Caenorhabditis elegans model system. The E. coli strains resulted in severe morphological and physiological damage to the worm whereas the probiotic interventions were able to reduce these damages.

Host‐driven hepatic conversion of gut microbiota‐derived putrescine to spermidine mediates mannose's protective effects against hepatic steatosis in zebrafish

iMeta, EarlyView.
Evidence for liver metabolism of gut‐derived microbial compounds into beneficial secondary metabolites has been lacking. Here, we demonstrate that Cetobacterium somerae (C. somerae), enriched by mannose supplementation under high‐fat diet conditions, convert arginine into putrescine.

Aggregation‐induced emission luminogens in in vitro diagnostics: Advancing biomarker detection in body fluids

Interdisciplinary Medicine, EarlyView.
This review systematically summarizes recent advances in aggregation‐induced emission (AIE) materials for in vitro diagnostics (IVD). It highlights probe design strategies—categorizing them into direct‐responsive, indirect‐responsive, and nano‐immunoprobes—and their applications in detecting a wide range of biomarkers across diverse body fluids ...
