Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Genetic suppression of cryoprotectant toxicity

Cryobiology, 2019
We report here a new, unbiased forward genetic method that uses transposon-mediated mutagenesis to enable the identification of mutations that confer cryoprotectant toxicity resistance (CTR). Our method is to select for resistance to the toxic effects of M22, a much-studied whole-organ vitrification solution.

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

Subregion‐specific perineuronal net remodelling in the dorsal hippocampus drives vulnerability and resilience to chronic stress: The role of venlafaxine treatment

British Journal of Pharmacology, EarlyView.
Background and Purpose Neuronal plasticity enables the brain to adapt to internal and external demands by dynamically regulating synaptic connectivity and emotional circuitry. Impaired neuroplasticity represents a core pathophysiological framework of major depressive disorder, one of the leading causes of disability worldwide. Chronic stress is a major

Human Pancreatic Cancer Organoids

Cell Proliferation, EarlyView.
This guideline establishes a comprehensive framework for the application of patient‐derived pancreatic cancer organoids. It outlines the stringent technical requirements and testing methods necessary to ensure high fidelity to the original tumor tissue, including morphological assessment, pathological biomarker expression (e.g., CK19, CK7), and genetic
