MRI-Derived Transition Zone Index Is Highly Predictive of Urodynamic Bladder Outlet Obstruction Prior to Holmium Laser Enucleation of the Prostate.

Introduction And Objective: Urodynamic study (UDS) is required to diagnose bladder outlet obstruction (BOO) during evaluation of benign prostatic hyperplasia (BPH) but is seldom performed due to cost and invasiveness. Therefore, anatomic and clinical parameters to predict BOO have been proposed, including the prostate transition zone index (TZI) which is the ratio of prostate transition zone volume (TZV) to whole gland volume (WGV). Historically computed with ellipsoid volume estimation of prostate WGV and TZV from transrectal ultrasound measurements, controversy exists regarding the utility of TZI to predict likelihood of BOO on UDS and clinical outcomes following BPH surgery.

Dileucine ingestion, but not leucine, increases lower body strength and performance following resistance training: A double-blind, randomized, placebo-controlled trial.

Background: The essential amino acid leucine (LEU) plays a crucial role in promoting resistance-training adaptations. Dileucine (DILEU), a LEU-LEU dipeptide, increases MPS rates, however its impact on resistance training outcomes remains unexplored. This study assessed the effects of DILEU supplementation on resistance training adaptations.

Effects of and extract on cognitive function in a healthy adult population: a double-blind, randomized, placebo-controlled trial.

Unlabelled: Flavonoids, known for their neuroprotective properties, are abundant in and Yet, human studies on their combined effects are limited.

Objective: This study evaluated the cognitive effects of combined and supplementation in healthy adults.

Methods: In a randomized, double-blind, placebo-controlled trial, 26 males and 59 females ( = 85; 43 ± 8 yrs) consumed the test product (TP) containing 240 mg stem extract of and 51 mg heartwood extract of (UP326, Unigen, Tacoma, WA USA) or placebo (PLA) for four weeks.

Controllable orbital angular momentum monopoles in chiral topological semimetals.

The emerging field of orbitronics aims to generate and control orbital angular momentum for information processing. Chiral crystals are promising orbitronic materials because they have been predicted to host monopole-like orbital textures, where the orbital angular momentum aligns isotropically with the electron's crystal momentum. However, such monopoles have not yet been directly observed in chiral crystals.
