Tissue Responses to Shiga Toxin in Human Intestinal OrganoidsSummary
Cellular and Molecular Gastroenterology and Hepatology, 2020 Background & Aims: Shiga toxin (Stx)-producing Escherichia coli (eg, O157:H7) infection produces bloody diarrhea, while Stx inhibits protein synthesis and causes the life-threatening systemic complication of hemolytic uremic syndrome.

Robust Estimation and Inference for Time‐Varying Unconditional Volatility
Journal of Time Series Analysis, EarlyView.ABSTRACT We derive a general and robust estimator of a large class of parametric specifications of time‐varying unconditional volatility of financial returns, both univariate and multivariate, and establish the Consistency and Asymptotic Normality (CAN) of the estimator.

A Rapid and Sensitive Method to Measure the Functional Activity of Shiga Toxins in Human Serum
Toxins, 2015 Shiga toxins (Stx) have a definite role in the development of hemolytic uremic syndrome in children with hemorrhagic colitis caused by pathogenic Stx-producing Escherichia coli (STEC) strains. The dramatic effects of these toxins on the microvasculature

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1741-1754, October 2026.ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

Effects ofSaxitoxin (STX) and Veratridine on BacterialNa + -K + Fluxes: a Prokaryote-BasedSTXBioassay [PDF]
Applied and Environmental Microbiology, 2003 ABSTRACT Saxitoxin (STX) is a potent natural sodium channel blocker and represents a significant health concern worldwide. We describe here the antagonistic effects of STX and veratridine (VTD), an Na + channel activator, on three gram-negative bacteria and their application to an STX bioassay. STX reduced

Proteasome inhibitors prevent cell death and prolong survival of mice challenged by Shiga toxin
FEBS Open Bio, 2015 Shiga toxin (Stx) causes fatal systemic complications. Stx induces apoptosis, but the mechanism of which is unclear. We report that Stx induced rapid reduction of short‐lived anti‐apoptotic proteins followed by activation of caspase 9 and the progression
