"Popping the Ion-Basket": Enhancing Thermoelectric Performance of Conjugated Polymers by Blending with Latently Dissociable Perovskite Quantum Dots.

A novel additive method to boost the Seebeck coefficient of doped conjugated polymers without a significant loss in electrical conductivity is demonstrated. Perovskite (CsPbBr) quantum dots (QDs) passivated by ligands with long alkyl chains are mixed with a conjugated polymer in a solution phase to form polymer-QD blend films. Solution sequential doping of the blend film with AuCl solution not only doped the conjugated polymer but also decomposed the QDs, resulting in a doped conjugated polymer film embedded with separated ions dissociated from the QDs.

Application of Orofacial Muscle Strength Measurement to Screen for Penetration/Aspiration Risk in Older Adults With Sarcopenia: A Diagnostic Accuracy Study.

Background: Early identification of penetration/aspiration (P/A) risk in older adults with sarcopenia is crucial to prevent complications and maintain quality of life.

Purpose: To evaluate the diagnostic utility of orofacial muscle strength measurements for predicting the risk of P/A in older adults with sarcopenia.

Methods: In this observational and prospective study, we collated consecutive data from community-dwelling older adults diagnosed with sarcopenia at a musculoskeletal disorder clinic.

Junctional Role of Anionic Domain of Mussel Foot Protein Type 4 in Underwater Mussel Adhesion.

Mussel byssi form a robust underwater adhesive system, anchoring to various surfaces in harsh marine environments. Central to byssus is foot protein type 4 (fp-4), a junction protein connecting collagenous threads to proteinaceous plaque. This study investigated an anionic plaque-binding domain of fp-4 (fp-4a) and its interactions with cationic foot proteins (fp-1, fp-5, and fp-151 as model substitutes for fp-2) and metal ions (Ca, Fe, and V).

Canine Stem Cell-derived Exosomes for Lung Inflammation: Efficacy of Intratracheal Intravenous Administration in an Acute Lung Injury Mouse Model.

Background/aim: Acute lung injury (ALI) is an important pathological process in acute respiratory distress syndrome; however, feasible and effective treatment strategies for ALI are limited. Recent studies have suggested that stem cell-derived exosomes can ameliorate ALI; however, there remains no consensus on the protocols used, including the route of administration. This study aimed to identify the appropriate route of administration of canine stem cell-derived exosomes (cSC-Exos) in ALI.

Non-operative treatment in advanced atraumatic osteonecrosis of the humeral head in patients under 50 years old: an observational study.

The humeral head is the second most common anatomical site of osteonecrosis after the femoral head. Studies have reported satisfactory clinical outcomes after shoulder arthroplasty to treat osteonecrosis of the humeral head (ONHH). However, there are concerns regarding implant longevity in relatively young patients.
