Standardisation of Dog Sperm Morphology Classification
Reproduction in Domestic Animals, Volume 60, Issue 2, February 2025.ABSTRACT Sperm morphology is an important component of dog fertility analysis. Visual examination is the gold standard technique for evaluation, but large variations within and across evaluators have been documented. Databases of sperm morphology images are valuable practical aids for training and performance testing and can improve sperm ...

Patterns in Space: Coordinating Adhesion and Actomyosin Contractility at E-cadherin Junctions [PDF]
, 2013 Cadherin adhesion receptors are fundamental determinants of tissue organization in health and disease. Increasingly, we have come to appreciate that classical cadherins exert their biological actions through active cooperation with the contractile actin cytoskeleton.

The contractile vacuole in Ca(2+)-regulation in Dictyostelium: its essential function for cAMP-induced Ca(2+)-influx [PDF]
, 2006 BACKGROUND: cAMP-induced Ca(2+)-influx in Dictyostelium is controlled by at least two non-mitochondrial Ca(2+)-stores: acidic stores and the endoplasmic reticulum (ER).

The effect of ionizing radiation on testicular interstitial stromal cells
Reproductive Medicine and Biology, Volume 24, Issue 1, January/December 2025.The interstitial stromal cells play an important supportive role in male fertility, but radiation‐induced damage to these cells is still poorly understood. We aimed to investigate the impact of a high (1 Gy) and very high (8 Gy) single pelvic radiotherapy on pubertal testicular histology and factors such as CSF‐1R, CD105, FGF2, and GNDF to study the ...

Superoxide dismutase C and Ras affects Dictyostelium Contractile vacuole morphogenesis and function [PDF]
, 2017 Dictyostelium cells lacking SodC displayed severely compromised CV morphogenesis and function. The sodC- cells were vulnerable to hypotonic stress and showed poorly developed CV tubules, significant increase in the number of CV bladders, and a prolonged ...

Journal of Eukaryotic Microbiology, Volume 72, Issue 1, January/February 2025.Abstract The globally distributed ciliate Balanion planctonicum is a primary consumer of phytoplankton spring blooms. Due to its small size (~20 μm), identification and quantification by molecular tools is preferable as an alternative to the laborious counting of specimen in quantitative protargol stains. However, previous sequencing of the 18S rDNA V9
