Impact of varicocoelectomy on male semen parameters: A long‐term analysis of sperm quality and outcomes

Andrology, Volume 14, Issue 2, Page 352-357, February 2026.
Abstract Background Varicocoeles are common in 40% of men presenting with infertility. Semen parameters including sperm motility, low sperm count and sperm morphology are altered by the presence of varicocoeles. Though varicocoelectomy has been associated with improvements in these parameters, studies on long‐term outcomes are limited.

Regulation of T cell lymphokine production by killer cell inhibitory receptor recognition of self HLA class I alleles. [PDF]

, 1996
The killer cell inhibitory receptors (KIRs) are surface glycoproteins expressed by natural killer (NK) and T cells that specifically recognize defined groups of polymorphic human histocompatibility leukocyte antigen (HLA) class I molecules.

Effects of Defined Pig Microbiota on Acute Salmonellosis in Gnotobiotic Piglets

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
Germ‐free piglets lack protective microbiota and are highly vulnerable to Salmonella Typhimurium LT2 infection. Pre‐colonization with defined pig microbiota supports early immune response and intestinal barrier maturation. By measuring pathogen spread, intestinal structure, goblet cell density, cytokines, and tight‐junction markers with molecular and ...

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

FEBS Open Bio, Volume 16, Issue 1, Page 161-177, January 2026.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

Development of a procedure for isolation, identification and quality assessment of bovine spermatids and evaluation of their fertilizing ability in vitro

Frontiers in Bioengineering and Biotechnology
Intracytoplasmic spermatid injection into oocytes has limited efficiency in cattle, with no offspring generated so far, partly due to ambiguous spermatid identification.

Differentiation Treatment Applied to Lung Cancer Model Reduces Pathogenic Traits in Vitro

Advanced Biology, Volume 10, Issue 1, January 2026.
Non‐small cell lung cancer cells (A549) treated with a differentiation medium showed strong reduction in proliferation, migration, clonogenicity, spheroid formation and stemness markers, with enhanced adhesion properties and alveolar features, all pointing to a notably less aggressive phenotype in support of differentiation therapy as a promising ...

Shedding Light on the Cellular Uptake Mechanisms of Bioactive Glass Nanoparticles as Controlled Intracellular Delivery Platforms: A Review of the Recent Literature

Advanced Healthcare Materials, Volume 15, Issue 1, 9 January 2026.
This review summarizes the main uptake pathways of bioactive glass nanoparticles (BGNs) and their intracellular localization, highlighting that BGNs are mainly internalized and entrapped within endosomes/lysosomes. Strategies for controlled intracellular ion release, with implications for targeted modulation of cell behavior, are discussed. The need to
