A Drosophila Model for Clostridium difficile Toxin CDT Reveals Interactions with Multiple Effector Pathways. [PDF]

open access: yes, 2020
Clostridium difficile infections (CDIs) cause severe and occasionally life-threatening diarrhea. Hyper-virulent strains produce CDT, a toxin that ADP-ribosylates actin monomers and inhibits actin polymerization.

Alnustone Ameliorates Metabolic Dysfunction‐Associated Steatotic Liver Disease by Facilitating Mitochondrial Fatty Acid β‐Oxidation via Targeting Calmodulin

open access: yesAdvanced Science
Metabolic dysfunction‐associated steatotic liver disease (MASLD), including its more severe manifestation metabolic dysfunction‐associated steatohepatitis (MASH), poses global public health threats with limited therapeutics.

Genetic Diversity, Ochratoxin A and Fumonisin Profiles of Strains of Aspergillus Section Nigri Isolated from Dried Vine Fruits

open access: yesToxins, 2020
We investigated ochratoxin A (OTA) contamination in raisin samples purchased from Slovak markets and determined the diversity of black-spored aspergilli as potential OTA and fumonisin (FB1 and FB2) producers.

The Goldfish as a Model for Studying Neuroestrogen Synthesis, Localization, and Action in the Brain and Visual System [PDF]

open access: yes, 2011
Organizational and activational effects of estrogen (E) in the central nervous system (CNS) are exerted directly by circulating E and indirectly after aromatization of circulating androgen to E in the brain itself. Understanding an environmental chemical'

Protection Against Cardiac Injury by Small Ca\u3csup\u3e2 +\u3c/sup\u3e-Sensitive K\u3csup\u3e+\u3c/sup\u3e Channels Identified in Guinea Pig Cardiac Inner Mitochondrial Membrane [PDF]

open access: yes, 2013
We tested if small conductance, Ca2 +‐sensitive K+ channels (SKCa) precondition hearts against ischemia reperfusion (IR) injury by improving mitochondrial (m) bioenergetics, if O2‐derived free radicals are required to initiate protection via SKCa ...

Tetanic Stimulation Leads to Increased Accumulation of Ca^(2+)/Calmodulin-Dependent Protein Kinase II via Dendritic Protein Synthesis in Hippocampal Neurons [PDF]

open access: yes, 1999
mRNA for the ɑ-subunit of CaMKII is abundant in dendrites of neurons in the forebrain (Steward, 1997). Here we show that tetanic stimulation of the Schaffer collateral pathway causes an increase in the concentration of ɑ-CaMKII in the dendrites of ...

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

open access: yesBMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Calcium retinoate nanoparticle mediated microglial polarization to regulate inflammatory microenvironment for therapy of neuroinflammatory disease

open access: yesBMEMat, EarlyView.
A nano‐drug based on retinoic acid and calcium is developed, which can be rapily endocytosed by microglia and decomposed into small molecule/ion storms in lysosomes. This nano‐drug regulates microglial phenotype switching from M1 to M2 while indirectly guiding neuronal differentiation of endogenous neural stem cells, thereby ameliorating ...
