Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

A CCNA1 Missense Variant Associated With Chromatid Non‐Disjunction in Abnormal‐Headed Sperm and Male Infertility

Andrology, EarlyView.
ABSTRACT Background Macrozoospermia is a rare form of teratozoospermia characterized by tetraploids, large‐headed spermatozoa with multiple flagella, usually caused by bi‐allelic AURKC mutations. The etiology of atypical phenotypes with a lower proportion of large headed spermatozoa and single flagella however often remains unresolved.

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

Biallelic Truncating Variant in LRGUK Is Associated With Severe Multiple Morphological Abnormalities of the Sperm Flagella and Sperm Nuclear Defects in Humans

Clinical Genetics, EarlyView.
A homozygous truncating variant in LRGUK results in loss of the LRGUK protein and causes multiple morphological abnormalities of the flagella (MMAF), disrupted axonemal architecture, central pair defects, abnormal chromatin organization, and severe male infertility, establishing LRGUK as a novel human infertility gene.

Cell‐Migration Visualization: Task Taxonomy, Systematic Review and Research Agenda

Computer Graphics Forum, EarlyView.
We present an expert‐validated task taxonomy for cell migration analysis and a PRISMA‐based systematic review that maps visualization tools to the tasks they support and the techniques they employ. This synthesis identifies current gaps and outlines opportunities for future research in cell migration visualization.

An Atypical Skin Presentation of Adult‐Onset Still's Disease With Histological Description: A Case Report

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Adult‐onset Still's disease (AOSD) is an auto inflammatory disorder with a variable clinical presentation, and without a pathognomonic diagnostic test, characterized by high spiking fever, arthralgia/arthritis, a suggestive skin rash, elevated white blood cell count 10 G/L (> 80% neutrophils), elevated ferritin, with glycosylated ferritin < 20%
