Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

open access: yesAndrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Improving ARTs: Microfluidics as a Tool for Sperm Selection

open access: yesAndrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Seminal Biomarkers and Sperm Proteomic Signatures Differentiate Acute and Chronic Male Accessory Gland Inflammation

open access: yesAndrology, EarlyView.
ABSTRACT Background Male accessory gland inflammation (MAGI) comprises a heterogeneous group of inflammatory conditions that may differentially affect the seminal microenvironment and sperm function. However, whether transrectal ultrasound (TRUS)‐defined MAGI phenotypes correspond to distinct biological profiles remains insufficiently characterized ...

Ischaemic Optic Neuropathy After Cardiac Surgery: A Systematic Review and Meta‐Analysis of Incidence and Risk Factors

open access: yesANZ Journal of Surgery, EarlyView.
Across 11 observational studies comprising 6 471 577 patients, the pooled incidence of ischaemic optic neuropathy after cardiac surgery was approximately 1.5 cases per 10 000 procedures. Coronary artery disease, peripheral vascular disease and anaemia were associated with increased odds of ION, although these findings should be interpreted in the ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and
