Metabolomic and lipidomic signatures of Helicobacter pylori infection: Unveiling biochemical pathways associated with neurodegeneration

iMetaOmics, EarlyView.
Our study employed an integrated lipidomics and metabolomics approach to elucidate Helicobacter pylori‐driven metabolic perturbations along the gut–brain axis. H. pylori infection was established in gastric epithelial (AGS) cells, and the resulting conditioned media (secretome) was collected and exposed to neuronal (IMR‐32) cells.

Fluorometric Determination of Urinary Metanephrine and Normetanephrine

Clinical Chemistry, 1964
Abstract A detailed procedure for the quantitative determination of metanephrine and normetanephrine is given. Epinephrine and norepinephrine are eliminated by selective adsorption on an alumina column. Metanephrine and normetanephrine are isolated with a cation-exchange resin.

Optimized procedures for testing plasma metanephrines in patients on hemodialysis

Scientific Reports, 2021
Diagnosis of pheochromocytomas and paragangliomas in patients receiving hemodialysis is troublesome. The aim of the study was to establish optimal conditions for blood sampling for mass spectrometric measurements of normetanephrine, metanephrine and 3 ...

Biochemical analysis and management of phaeochromocytoma: A case report

Ibom Medical Journal, 2023
Phaeochromocytoma is a tumour from chromaffin cells in adrenal medulla or extra-adrenal autonomic ganglia, usually releasing catecholamines and metanephrines. It is an unusual cause of severe hypertension in the young.

Hypertensive emergency and type 2 myocardial infarction resulting from pheochromocytoma and concurrent capnocytophaga canimorsus infection [PDF]

, 2014
A diagnosis of myocardial infarction is made using a combination of clinical presentation, electrocardiogram and cardiac biomarkers. However, myocardial infarction can be caused by factors other than coronary artery plaque rupture and thrombosis.

Lipid Profile in Primary Aldosteronism: Cross‐Sectional and Post‐Treatment Analyses

Lipids, EarlyView.
ABSTRACT The relationship between primary aldosteronism (PA) and lipid metabolism remains controversial, with inconsistent findings reported in the literature. This study aimed to clarify PA's impact on the lipid profile using both a cross‐sectional comparison with essential hypertension (EH) controls and a longitudinal within‐patient pre‐post ...

Routine genetic screening with a multi-gene panel in patients with pheochromocytomas [PDF]

, 2017
PURPOSE: Several new gene mutations have been reported in recent years to be associated with a risk of familial pheochromocytoma. However, it is unclear as to whether extensive genetic testing is required in all patients. METHODS: The clinical data

BSAVA Petsavers Article: Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, EarlyView.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...
