Immunophenotypic assessment of pure embryonal carcinoma and yolk sac tumour suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche

Histopathology, EarlyView.
Immunohistochemical analysis of transcription factors in GCNIS associated with pure EC and YST suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche. In these tumors, reprogramming may occur immediately upon invasion of the stroma or within seminiferous tubules but outside the spermatogonial niche (i.e., in intratubular ...

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Lipofuscin: The Missing Link in the Worsening of Obstructive Sleep Apnea

The Laryngoscope, Volume 136, Issue 5, Page 2362-2369, May 2026.
Lipofuscin, also known as the age pigment, is a permanent autofluorescent intracellular deposit that accumulates with aging or oxidative stress, thereby interfering with cellular function. This study revealed significantly larger deposits of lipofuscin in the lateral pharyngeal wall muscles of patients with severe obstructive sleep apnea (OSA) compared

Prevalence and age-related trends of high-risk Human Papillomavirus genomes in Ecuadorian women: a comprehensive cross-sectional study

BMC Infectious Diseases
Background Human Papillomavirus (HPV) is a leading cause of cervical cancer worldwide. Previous studies on HPV prevalence in Ecuador have presented inconsistent findings due to limited sample sizes and regional foci.

Platelet‐Activating Factor Pathway in Women With Metabolic Dysfunction‐Associated Steatotic Liver Disease and Obesity

Obesity, Volume 34, Issue 5, Page 1056-1067, May 2026.
Increased hepatic PAFR expression in MASLD is associated with histological disease severity and may contribute to progression through platelet activation, whereas circulating Lp‐PLA2 levels lack discriminatory value as a noninvasive biomarker. ABSTRACT Objective This study aimed to investigate the platelet‐activating factor (PAF) pathway in obesity ...
