Lacticaseibacillus rhamnosus HA-114 and Bacillus subtilis R0179 Prolong Lifespan and Mitigate Amyloid-β Toxicity in C. elegans via Distinct Mechanisms.

Background: Recent advances linking gut dysbiosis with neurocognitive disorders such as Alzheimer's disease (AD) suggest that the microbiota-gut-brain axis could be targeted for AD prevention, management, or treatment.

Objective: We sought to identify probiotics that can delay Aβ-induced paralysis.

Methods: Using C.

Sedation practices in gastrointestinal endoscopy-A survey from southern India.

Gastrointestinal endoscopies can cause an unpleasant experience for the patient. In India, most endoscopists follow a common institutional policy for sedation. The aim of this study was to analyze the sedation practices in various endoscopy centers across southern India.

The cooperation of enamelin and amelogenin in controlling octacalcium phosphate crystal morphology.

Enamel matrix proteins, including the most abundant amelogenin and lesser amounts of enamelin, ameloblastin, and proteinases, play vital roles in controlling crystal nucleation and growth during enamel formation. The cooperative action between amelogenin and the 32-kDa enamelin is critical to regulating the growth morphology of octacalcium phosphate crystals. Using biophysical methods, we investigated the interaction between the 32-kDa enamelin and recombinant pig amelogenin 148 (rP148) at pH 6.

Imatinib-induced pancreatitis.

Drug-induced pancreatitis is a rare but serious complication of many drugs, some of which have been well documented. Here we present a case of a middle-aged man with chronic myeloid leukemia who developed acute pancreatitis after being initiated on imatinib mesylate. The case history, the pharmacodynamics, uses, and adverse effects of imatinib mesylate are discussed in detail.

Immunogenic potential of Enterococcus faecalis biofilm under simulated growth conditions.

Introduction: The aim of this study was to evaluate the effect of growth modes (planktonic and biofilms) of Enterococcus faecalis on the intracellular survival and ability to produce tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-6 after interacting with monocytes/in vitro-differentiated macrophages.

Methods: In vitro biofilms of three E. faecalis strains (ATCC-29212, OG1RF, and FA2-2) were grown on dentin under simulated nutrient-rich and nutrient-deprived conditions.

Influence of irrigation regimens on the adherence of Enterococcus faecalis to root canal dentin.

Enterococcus faecalis is frequently associated with post-treatment endodontic infections. Because adherence of bacteria to a substrate is the earliest stage in biofilm formation, eliciting the factors that links adherence of this bacterium to dentin would help in understanding its association with treatment-failed root canals. This investigation aimed to study the effects of endodontic irrigants on the adherence of E.
