Lower developmental potential of rat zygotes produced by ooplasmic injection of testicular spermatozoa versus cauda epididymal spermatozoa

open access: yesThe Journal of Reproduction and Development
Intracytoplasmic sperm injection (ICSI) is clinically used to treat obstructive/nonobstructive azoospermia. This study compared the efficacy of ICSI with cauda epididymal and testicular sperm in Wistar (WI) and Brown-Norway (BN) rats.

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Relationship between Potential Sperm Factors Involved in Oocyte Activation and Sperm DNA Fragmentation with Intra-Cytoplasmic Sperm Injection Clinical Outcomes

open access: yesCell Journal, 2016
Objective: The present study aimed to simultaneously evaluate the association between expression of three potential factors [post-acrosomal sheath WW domain-binding protein (PAWP), phospholipase Cζ (PLCζ), and truncated form of the kit receptor (TR ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Experimental models of cerebral small vessel disease: Physiological constraints, translational challenges and future directions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Overview of cerebral small vessel disease (cSVD) pathophysiology and current modelling challenges. Left: clinical burden and key unresolved research questions. Right: neurovascular unit (NVU) architecture highlighting sites of cSVD pathology across arterioles, capillaries and venules, including interactions between endothelial ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, Volume 41, Issue 7, Page 379-394, July 2026.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Comparative Effects of Laparotomy and Laparoscopy‐Assisted Embryo Transfer on Oxidative Stress and Thiol–Disulphide Homeostasis in Tuj Ewes

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Laparoscopic embryo transfer in Tuj ewes induces less oxidative stress and better preserves thiol–disulphide homeostasis than laparotomy. These findings indicate that minimally invasive approaches better maintain redox balance and antioxidant defence during embryo transfer procedures.

Reactive Oxygen Species‐Induced Damage in Cryopreserved Bovine Sperm: Mitigation Strategies

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Cryopreservation of bovine sperm results in overproduction of ROS due to osmotic pressure variations, ice crystals and dysfunction of mitochondria, which causes lipid peroxidation, fragmentation of DNA, protein damage and ultimately decline of post‐thaw sperm quality.
