Apparent Bilateral Aldosterone Suppression During Adrenal Vein Sampling: An Artefact of the Liaison Chemiluminescence Immunoassay and Other Causes Revealed by Comparisons With Another Commercial Immunoassay and Mass Spectrometry

open access: yesClinical Endocrinology, Volume 105, Issue 2, Page 175-184, August 2026.
ABSTRACT Objective Subtyping of primary aldosteronism usually requires adrenal vein sampling (AVS). Interpretation can be compromised by apparent bilateral aldosterone suppression (ABAS), which we hypothesised reflects an artefact of the Liaison immunoassay of aldosterone.

IgG4‐Related Disease Overlapping With Anti‐Acetylcholine Receptor Antibody–Positive Myasthenia Gravis

open access: yesClinical and Experimental Neuroimmunology, Volume 17, Issue 3, August 2026.
ABSTRACT Background IgG4‐related disease (IgG4‐RD) is a systemic, immune‐mediated, fibroinflammatory disorder with multiorgan involvement and variable clinical presentation, often creating diagnostic difficulty. Myasthenia gravis (MG) is an antibody‐mediated autoimmune disorder of the neuromuscular junction, most commonly associated with anti ...

Clinical Implications and Research Progress of Salivary Biomarkers for Endocrine and Metabolic Disorders

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 6561-6575, August 2026.
ABSTRACT Aims Similar to blood, saliva contains a broad range of biomarkers and may offer a non‐invasive, repeatable specimen for endocrine and metabolic assessment. This review aims to synthesise and evaluate recent advances in the clinical translation of salivary biomarkers, while providing a critical assessment of the diagnostic reliability and ...

Acute GIP and GLP‐1 Administration Exerts Differential Metabolic Effects in Totally Pancreatectomised Individuals

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 7280-7290, August 2026.
ABSTRACT Aims While being recognised for stimulating pancreatic insulin secretion, GIP and GLP‐1 exert various extrapancreatic effects relevant in the context of incretin‐based therapies. Here, we evaluated the extrapancreatic effects of GIP and GLP‐1, separately and combined, on postprandial physiology in totally pancreatectomised individuals ...

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

open access: yesJournal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...

Salivary estradiol and progesterone across the menstrual cycle: Association and agreement with serum concentrations

open access: yesPhysiological Reports, Volume 14, Issue 15, August 2026.
Abstract Saliva provides a noninvasive alternative to serum for serial sampling of estradiol and progesterone. This study examined salivary estradiol and progesterone patterns and the relationship between salivary and serum estradiol, progesterone, and the estradiol to progesterone ratio (E2:P) across the menstrual cycle (MC) in physically active ...

Aquaporin‐4 in Narcolepsy Type 1: Investigation of Perivascular Fluid Movement in Sleep Disorders

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1498-1502, July 2026.
ABSTRACT Narcolepsy type 1 (NT1) is caused by the loss of hypocretin‐1 leading to excessive daytime sleepiness and cataplexy. Additionally, disrupted nighttime sleep has become an increasingly recognized feature of NT1. As the glymphatic fluid movement has been linked to sleep architecture, we investigated cerebrospinal fluid (CSF) Aquaporin‐4 (AQP4 ...

Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.

Quantitative Mass Spectrometry‐Based Biodistribution of Monoclonal Antibodies: An Alternative to Radio‐Biodistribution

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
Monoclonal antibodies are powerful anticancer therapeutics targeting tumor‐associated antigens. Mass spectrometry enables precise and accurate quantification of mAbs in tumor plasma and healthy organs. Unlike ligand binding assay and radioactivity, mass spectrometry does not suffer from matrix effects and labelling artefacts while facilitating method ...
