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.

Microelectrode arrays of diamond-insulated graphitic channels for real time detection of exocytotic events from cultured chromaffin cells and slices of adrenal glands [PDF]

, 2016
A microstructured graphitic 4x4 multielectrode array was embedded in a single crystal diamond substrate (4x4 {uG-SCD MEA) for real-time monitoring of exocytotic events from cultured chromaffin cells and adrenal slices.

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 ...

Ca2+ binding to Chromaffin Vesicle Matrix Proteins [PDF]

, 1986
Recently we found that Ca2+ within chromaffin vesicles is largely bound [Bulenda, D., & Gratzl, M. (1985) Biochemistry 24, 7760-77651. In order to explore the nature of these bonds, we analyzed the binding of Ca2+ to the vesicle matrix proteins as well ...

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

One-Year Chromaffin Cell Allograft Survival in Cancer Patients with Chronic Pain: Morphological and Functional Evidence

Cell Transplantation, 1998
The control of chronic pain through transplantation of chromaffin cells has been reported over the past few years. Analgesic effects are principally due to the production of opioid peptides and catecholamines by chromaffin cells.

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish Species

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors.

A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study

Advanced Biology, Volume 9, Issue 12, December 2025.
Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...
