Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

Comprehensive analysis of microtubule‐inhibiting herbicides reveals shared subcellular phenotypes and distinct resistance profiles

open access: yesPest Management Science, EarlyView.
Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...

Clinical benefit of metaphase I oocytes

open access: yesReproductive Biology and Endocrinology, 2005
Background We studied the benefit of using in vitro matured metaphase I (MI) oocytes for ICSI in patients with a maximum of 6 mature metaphase II (MII) oocytes at retrieval.

Mosaic Ring-like Small Supernumerary Marker Chromosome and Gene Mutation in a Male With Intermittent Azoospermia: A Rare Case Report

open access: yesAmerican Journal of Men's Health, 2020
This study aimed to report a rare case of intermittent azoospermia and ring-like small supernumerary marker chromosomes (sSMCs). An infertile man was diagnosed with azoospermia presenting a normal male phenotype with complete masculinization. Karyotyping

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Structure of human metaphase chromosomes

open access: yesHereditas, 2008
Human metaphase chromosomes possesss an organized axial structure retaining the helical pattern of the chromatid macrocoil (Ohnuki-coil) after the dispersion of virtually all chromatin. This result is based on electron microscopy of chromosomes treated with alkaline pH or hot phosphate and stained with silver nitrate or phosphotungstic acid.
