The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Is semen analysis without strict criteria misleading decisions in IVF? A prospective systematic study

International Journal of Reproductive BioMedicine, 2018
Background: Sperm morphology has been strongly linked to fertilization. This makes it an important component in semen analysis. They are usually assessed by world health organization (WHO) standard or Kruger strict criteria in in-vitro fertilization (IVF)

Protective Effect of All-Trans Retinoic Acid in Cisplatin-Induced Testicular Damage in Rats

The World Journal of Men's Health, 2019
Purpose: To investigate the effects of all-trans retinoic acid (ATRA) in cisplatin (CP)-induced testicular damage in rats. Materials and Methods: Twenty-eight male Wistar rats were divided into four groups: Control, ATRA alone, ATRA+CP, and CP alone ...

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

Advanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

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.

Contribution of Bacterial Infection to Male Infertility in Nigerians [PDF]

, 2009
There is disagreement as to the influence of certain microbial infection on male infertility and such agents are ignored. The incidence of these microbial agents in seminal fluid isolates is on the increase.

Genome Sequencing in 19 Families With Bladder Exstrophy and Epispadias Complex Indicates Involvement of the ADGR‐Gene Family

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Bladder exstrophy and epispadias complex (BEEC) is one of the most severe congenital malformations of the urogenital tract, significantly impacting continence, sexual function, and renal function. To date, the only recurrent genetic aberration identified is the 22q.11.2 microduplication, but several candidate regions and genes including ...

Use of endocrine and immune responses as predictors of bull sperm motility [PDF]

, 2015
Research has shown that peripheral blood cell populations change in response to an immune challenge, and hormone concentrations directly affect sperm characteristics.

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.
