MTCA‐Net: Multi‐Task Cascade Analysis Network for Real‐Time Sperm Quality Analysis

Advanced Intelligent Systems, EarlyView.
This article proposes MTCA‐Net, a multi‐task cascaded analysis network for real‐time sperm quality assessment in intracytoplasmic sperm injection. The framework integrates detection, tracking, and segmentation modules to jointly analyze sperm morphology and motility.

Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

Variation in Mating Dynamics across Five Species of Leiobunine Harvestmen (Arachnida: Opliones) [PDF]

, 2018
The study of mating choices often focuses on correlates of traits to the overall outcome of a mating interaction. However, mating interactions can proceed through a series of stages, with opportunities for assessment at each stage.

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

Advanced NanoBiomed Research, EarlyView.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

Intraspecific divergence in sperm morphology of the green sea urchin, Strongylocentrotus droebachiensis: implications for selection in broadcast spawners

BMC Evolutionary Biology, 2008
Background Sperm morphology can be highly variable among species, but less is known about patterns of population differentiation within species. Most studies of sperm morphometric variation are done in species with internal fertilization, where sexual ...

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]

, 2020
Although thousands of genetically modified mouse strains have been cryopreserved by sperm freezing, the likelihood of cryorecovery success cannot be accurately predicted using conventional sperm parameters.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of
