Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, Volume 9, Issue 1, January 2026.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...

GABA signaling and neuroactive steroids in adrenal medullary chromaffin cells

Frontiers in Cellular Neuroscience, 2016
GABA is produced not only in the brain, but also in endocrine cells by the two isoforms of glutamic acid decarboxylase (GAD), GAD65 and GAD67. In rat adrenal medullary chromaffin cells only GAD67 is expressed, and GABA is stored in large dense core ...

Navigating Solute Carrier Transporters—A Comprehensive Review of Functionalized Small Molecule Probes for Target Identification and Characterization

Medicinal Research Reviews, Volume 46, Issue 1, Page 238-271, January 2026.
ABSTRACT Solute carrier transporters (SLCs) are integral membrane proteins that play pivotal roles in maintaining cellular homeostasis by mediating the transport of a diverse range of substrates across cell membranes. With their involvement in fundamental physiological processes such as nutrient uptake, neurotransmitter signaling, and drug transport ...

Alcohol and the endocrine system: A critical review of disruptions, potential mechanisms, and health implications

Alcohol, Clinical and Experimental Research, Volume 50, Issue 1, January 2026.
The endocrine system coordinates whole body cellular function and maintains homeostasis. Alcohol impacts the integrity of endocrine regulation at multiple sites, contributing to risk for comorbidities. Some of the alcohol‐mediated pathophysiological effects on the endocrine system include alterations in receptor expression and responsiveness, protein ...

Functional distribution of Ca²⁺-coupled P2 purinergic receptors among adrenergic and noradrenergic bovine adrenal chromaffin cells

BMC Neuroscience, 2007
Background Adrenal chromaffin cells mediate acute responses to stress through the release of epinephrine. Chromaffin cell function is regulated by several receptors, present both in adrenergic (AD) and noradrenergic (NA) cells.

Plasma Membrane and Chromaffin Granule Characteristics in Digitonin‐Treated Chromaffin Cells [PDF]

Journal of Neurochemistry, 1985
Abstract: Digitonin permeabilizes the plasma membranes of bovine chromaffin cells to Ca2+, ATP, and proteins and allows micromolar Ca2+ in the medium to stimulate directly catecholamine secretion. In the present study the effects of digitonin (20 μM) on the plasma membrane and on intracellular chromaffin granules were further characterized. Cells with

Mass Spectrometric Measurements of 11‐Deoxycortisol, Androstenedione and Dehydroepiandrosterone Are Superior to Cortisol to Assess Selectivity of Non‐Stimulated Adrenal Vein Sampling

Clinical Endocrinology, Volume 104, Issue 1, Page 10-18, January 2026.
ABSTRACT Objective Successful adrenal venous sampling (AVS) is traditionally assessed using the ratio of cortisol in adrenal to peripheral venous plasma to calculate the selectivity index. With mass spectrometry other steroids can be simultaneously measured that may improve numbers of apparent successful sampling procedures.

11C‐Hydroxyephedrine PET/CT for preoperative surgical planning in large pheochromocytoma and paraganglioma

Journal of Neuroendocrinology, Volume 38, Issue 1, January 2026.
Abstract Early detection of metastases and timely surgical intervention play a crucial role in the management of neuroendocrine tumors. In large‐sized pheochromocytomas and sympathetic paragangliomas (PPGL), functional imaging with positron emission tomography (PET) is recommended, as it improves the detection of metastases, which may go undetected on ...

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Review of Pediatric Pheochromocytoma and Paraganglioma

Frontiers in Pediatrics, 2017
Pheochromocytoma (PCC) and paraganglioma (PGL) are rare chromaffin cell tumors which secrete catecholamines and form part of the family of neuroendocrine tumors.
