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, Volume 67, Issue 8, Page 680-685, August 2026.
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.

Hybrid Osprey‐Salp Swarm Optimization Algorithm for Single and Multiobjective Optimal Power Flow in Smart Grids With Renewable Energy Integration

Energy Science &Engineering, Volume 14, Issue 7, Page 3346-3387, July 2026.
The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Right Ventricular Function Improves With Pulmonary Vasodilator Treatment in Pediatric Patients With Pulmonary Hypertension and Multivessel Pulmonary Vein Stenosis in a Single Center Cohort

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Pulmonary hypertension (PH) and right ventricular (RV) dysfunction increase mortality in multivessel pediatric pulmonary vein stenosis (PVS). Pulmonary vasodilator use is limited in PVS due to the perceived risk of pulmonary edema. We aimed to describe our experience with pulmonary vasodilators in PVS and to assess changes in RV function and ...

The adjustable shunt valve in the treatment of adult hydrocephalus - Effect on clinical symptoms, intracranial pressure and complications

, 2014
Background: Hydrocephalus causes impaired gait, balance, cognition and continence, all of which can be reversed by shunt treatment. Adjustable valves are commonly used in the shunt treatment of hydrocephalus but randomized controlled trials (RCT) are ...
