Masticatory performance indicates the development of psychological frailty: A 6-year prospective cohort study by the SONIC study group.

Purpose: Although the association between oral health and physical frailty is well established, psychological frailty has not been investigated. Therefore, this prospective cohort study was conducted to examine the association between masticatory performance and psychological frailty in older community-dwelling Japanese individuals.

Methods: The participants included 498 older adults who completed baseline and 3- and 6-year follow-up surveys.

Polysulfur-based bulking of dynamin-related protein 1 prevents ischemic sulfide catabolism and heart failure in mice.

The presence of redox-active molecules containing catenated sulfur atoms (supersulfides) in living organisms has led to a review of the concepts of redox biology and its translational strategy. Glutathione (GSH) is the body's primary detoxifier and antioxidant, and its oxidized form (GSSG) has been considered as a marker of oxidative status. However, we report that GSSG, but not reduced GSH, prevents ischemic supersulfide catabolism-associated heart failure in male mice by electrophilic modification of dynamin-related protein (Drp1).

Isolation method of brain microvessels from small frozen human brain tissue for blood-brain barrier protein expression analysis.

Background: Protein expression analysis of isolated brain microvessels provides valuable insights into the function of the blood-brain barrier (BBB). However, isolation of brain microvessels from human brain tissue, particularly in small quantities, poses significant challenges. This study presents a method for isolating brain microvessels from a small amount of frozen human brain tissue, adapting techniques from an established mouse brain capillary isolation method.

Intra-individual polymorphisms in the mitochondrial COI gene of tick-killing Ixodiphagus wasps parasitizing Haemaphysalis flava ticks.

We present a case of an elderly man with a subcutaneous nodule in his lower leg that had persisted for four decades, accompanied by pain in the last several years. Imaging revealed a 20-mm elongated subcutaneous nodule along with a similar intraosseous lesion in the ipsilateral fibula.

Clinical characteristics of monoclonal immunoglobulin-associated renal disease: a retrospective cohort study.

Introduction: Clinical epidemiological data on monoclonal gammopathy of renal significance (MGRS) are lacking. In this retrospective observational study, MGRS was compared with B-cell or plasma cell malignancies (BCM/PCM) with renal involvement to clarify differences in their clinical features.

Methods: Among the 1408 renal biopsies performed at our hospital, 25 MGRS and 18 BCM/PCM patients were identified.

Progressive Amyloid-β Accumulation in the Brain leads to Altered Protein Expressions in the Liver and Kidneys of APP knock-in Mice.

Impaired hepatic and renal function influence Alzheimer's disease (AD) progression; however, whether AD progression affects these important organ functions remains unclear. Here, we investigated the impact of AD progression, characterized by brain amyloid-beta (Aβ) accumulation, on liver and kidney function of App (APP-KI) mice using quantitative proteomics. SWATH-based quantitative proteomics revealed changes in mitochondrial, drug metabolism, and pharmacokinetic-related proteins in mouse liver and kidneys during the early (2-month-old) and intermediate (5-month-old) stages of Aβ accumulation.

Decortication with uniport video-assisted thoracoscopic surgery for empyema due to postoperative esophageal leakage: a report of two pediatric cases.

Background: Video-assisted thoracoscopic surgery (VATS) is considered useful for the treatment of parapneumonic empyema in children. However, thoracoscopic management of empyema due to esophageal leakage as an operative complication has not been well described in the literature.

Case Presentation: We successfully decorticated severe empyema using uniport VATS in 2 children (a 2-year-old boy who suffered esophageal perforation after laparoscopic anti-reflux surgery, and a 7-month-old girl who had anastomotic leakage after thoracoscopic repair of esophageal atresia).

Implanted cartilaginous grafts following rhinoplasty: A retrospective histopathological study.

To describe histopathological features of rhinoplasty-related implanted cartilages, 83 cartilages surgically removed from 42 patients (2 men and 40 women) with a median age of 28.0 years (range, 21-47 years) following correction/revision rhinoplasty were examined. These cartilages included 16 autologous costal cartilages (ACCs), 14 irradiated homologous costal cartilages (IHCCs), 24 autologous nasal cartilages (ANCs), 2 irradiated homologous nasal cartilages (IHNCs), 14 autologous ear cartilages (ECs) and 13 combined cartilaginous grafts.

Ischemic fasciitis (IF) is a rare pseudosarcomatous lesion usually occurring in physically debilitated or immobilized, elderly patients. The current case presents a 76-year-old mobile man with IF on his back. The 33-mm subcutaneous lesion, focally involving the latissimus dorsi muscle, had been slowly increasing in size for 2 months and was clinically suggested to be a soft-tissue sarcoma.

Volumetric muscle composition analysis in sporadic inclusion body myositis using fat-referenced magnetic resonance imaging: Disease pattern, repeatability, and natural progression.

Introduction/aims: Fat-referenced magnetic resonance imaging (MRI) has emerged as a promising volumetric technique for measuring muscular volume and fat in neuromuscular disorders, but the experience in inflammatory myopathies remains limited. Therefore, this work aimed at describing how sporadic inclusion body myositis (sIBM) manifests on standardized volumetric fat-referenced MRI muscle measurements, including within-scanner repeatability, natural progression rate, and relationship to clinical parameters.

Methods: Ten sIBM patients underwent whole-leg Dixon MRI at baseline (test-retest) and after 12 months.

Design and Mechanistic Insights into α-Helical -Terphenyl Guanidines as Potent Small-Molecule Antifreeze Agents.

Ice formation is a critical challenge across multiple fields, from industrial applications to biological preservation. Inspired by natural antifreeze proteins, we designed and synthesized a new class of small-molecule antifreezes based on α-helical -terphenyl scaffolds with guanidine side chains. These -terphenyl guanidines , among the smallest molecules that mimic α-helical structures, exhibit potent ice recrystallization inhibition (IRI) activity, similar to that of existing large α-helical antifreeze compounds.
