Shiga Toxin (Stx) Classification, Structure, and Function [PDF]

Microbiology Spectrum, 2014
ABSTRACT Shiga toxin (Stx) is one of the most potent bacterial toxins known. Stx is found in Shigella dysenteriae 1 and in some serogroups of Escherichia coli (called Stx1 in E. coli ). In addition to or instead of Stx1, some E.

Assessing the role of plan complexity and target geometry through multi‐institutional gel based end‐to‐end QA in multi‐focal single isocenter stereotactic radiosurgery

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Single‐isocenter stereotactic radiosurgery enables efficient treatment of multiple brain metastases (SI‐MBM SRS), but demands high geometric accuracy. Plan complexity metrics are increasingly used as indicators for quality assurance (QA) performance, however their applicability to SRS remains uncertain, particularly in the context ...

454-Pyrosequencing: A Molecular Battiscope for Freshwater Viral Ecology [PDF]

, 2010
Viruses, the most abundant biological entities on the planet, are capable of infecting organisms from all three branches of life, although the majority infect bacteria where the greatest degree of cellular diversity lies.

Prospective Head Motion Correction in T1‐ and T2‐Weighted Long Echo Train Sequences Using Servo Navigation

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

Effect of anti-Stx IgY given via different routes from Stx on mortality of mice.

, 2013
(A) ppStx-1 (2.5 times LD50) and (B) ppStx-2 (2 times LD50) were administered i.p. to ddY mice. Anti-Stx-1 IgY and anti-Stx-2 IgY were given i.v. at doses of 50 and 100 mg/kg at 10 min before challenge. Control mice were given PBS instead of anti-Stx IgY.

Uncovering the Complex Transcriptome Response of Mytilus chilensis against Saxitoxin: Implications of Harmful Algal Blooms on Mussel Populations. [PDF]

PLoS ONE, 2016
Saxitoxin (STX), a principal phycotoxin contributing to paralytic shellfish poisoning, is largely produced by marine microalgae of the genus Alexandrium. This toxin affects a wide range of species, inducing massive deaths in fish and other marine species.

Dosimetric and radiobiological evaluations as well as technical aspects of left breast treatment employing DIBH with SGRT in radiotherapy with IMRT step and shoot, IMRT Dynamic MLC and VMAT

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Treatment of the left breast using deep inspiration breath hold (DIBH), combined with surface guided radiotherapy (SGRT), has emerged as the standard for reducing the dose to the heart, the left anterior descending coronary artery (LAD), and the ipsilateral lung.

Neutralizing activity of anti-Stx IgY.

, 2013
(A) hpStx-1, (B) hpStx-2 and (C) hpStx-2A1B were mixed with serial dilutions of anti-Stx-1 IgY and anti-Stx-2 IgY, and incubated for 1 h at 37°C. The mixture was subjected to the cytotoxicity assay.

Structural basis for saxitoxin congener binding and neutralization by anuran saxiphilins

Nature Communications
Dinoflagellates and cyanobacteria produce saxitoxin (STX) and ~50 congeners that disrupt bioelectrical signals by blocking voltage-gated sodium channels (NaVs). Consuming seafood carrying these toxins causes paralytic shellfish poisoning (PSP).
