Autologous minimally manipulated adipose‐derived stromal vascular fraction in knee osteoarthritis: Lasting symptom relief and imaging evidence from a 12‐month prospective study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the safety and efficacy of intra‐articular autologous transplantation of adipose‐derived connective tissue micrografts rich in stromal vascular fraction (CTM‐SVF), obtained using an enzyme‐free system (Hy‐Tissue® SVF) for knee osteoarthritis (OA). Methods Thirty patients (mean age of 53.3 ± 6.4 years) with Kellgren–Lawrence

Living with the Unknown: Intolerance of Uncertainty in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is marked by pervasive uncertainty due to fluctuating motor and non‐motor symptoms, variable treatment response, and an unpredictable clinical course. Intolerance of uncertainty (IU), a tendency to perceive ambiguity as threatening and respond with worry, avoidance, or decisional paralysis, may be ...

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Erratic behavior of platinum-group elements along an olivine–Cr-spinel cotectic in sulfide-undersaturated basaltic magma: roles of Cr-spinel and alloys

Scientific Reports
The behavior of platinum-group elements (PGE) in sulfide-undersaturated primitive magmas may be controlled by crystallization of either Cr-spinel, platinum-group minerals (PGM) or olivine.
