Tooth infections or injuries involving dental pulp are treated routinely by root canal therapy. Endodontically teeth devitalized, susceptible to re-infections, fractures, and subsequent tooth loss. Here, we report regeneration of dental-pulp-like tissue cell homing without transplantation. Upon in vivo implantation endodontically real-size, native human mouse dorsum for the tested 3 weeks, delivery basic fibroblast growth factor and/or vascular endothelial (bFGF VEGF) yielded re-cellularized...
We investigated the potential of a nanofiber-based poly(DL-lactide-co-glycolide) (PLGA) scaffold to be used for cartilage reconstruction. The mechanical properties nanofiber scaffold, degradation and cellular responses under stimulation were studied. Three different types (lactic acid/glycolic acid content ratio = 75 : 25, 50 50, or blend 25 50) tested. tensile modulus, ultimate stress corresponding strain scaffolds similar those skin slightly lower than human cartilage. This suggested that...
Gastric cancers have recently been classified into several types on the basis of molecular characterization, and new taxonomy has shown to clinical relevance. However, technology required for thorough classification is complicated expensive, currently preventing widespread use. We aimed reproduce results using only simple techniques, that is, immunohistochemical analysis in situ hybridization. a cohort 349 successive gastric adenocarcinomas 5 subtypes, protein or mRNA expression MLH1,...
We investigated the transport of neuronal mitochondria using superlocalized near-fields with plasmonic nanohole arrays (PNAs). Compared to traditional imaging techniques, PNAs create a massive array light beams and allow 3D mitochondrial dynamics be sampled extracted almost in real time. In this work, fluorescence excited by was captured an optical microscope dual objective lenses, which produced while minimizing scattering substrate. It found that move average velocity 0.33 ± 0.26 μm/s,...
Abstract This study aimed to evaluate the incidence rates of and risk factors for complex regional pain syndrome type 1 (CRPS-1) after surgery distal radius fractures (DRFs). Using data from January 2007 December 2014, we analysed Korean Health Insurance Review Assessment (HIRA) service. After extracting patients aged ≥18 years whose diagnostic operation codes DRFs were entered into HIRA database, CRPS-1. From 172,194 treated surgically. Within year postoperatively, 1,103 CRPS-1 cases...
Little is known about whether clones of ectopic, non-muscle stem cells contribute to muscle regeneration. Stem/progenitor that are isolated for experimental research or therapeutics typically heterogeneous. Non-myogenic lineages in a heterogeneous population conceptually may compromise tissue repair. In this study, we discovered mononucleated human tooth pulp fused into multinucleated myotubes robustly expressed myosin heavy chain vitro with without co-culture mouse skeletal myoblasts (C2C12...
The development of suitable synthetic scaffolds for use as human tendon grafts to repair ruptures remains a significant engineering challenge. Previous have demonstrated suboptimal tissue ingrowth and synovitis due wear particles from fiber-to-fiber abrasion. In this study, we present novel fiber-reinforced hydrogel (FRH) that mimics the hierarchical structure native graft material. Ultrahigh molecular weight polyethylene (UHMWPE) fibers were impregnated with either biosynthetic polyvinyl...
Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by ectopic bone formation. The anti-inflammatory function of dipeptidyl peptidase-4 (DPP4) inhibitor has been reported in metabolism, but its utility AS not previously investigated. We assessed DPP4 level serum, synovial fluid, and facet joint tissue patients. Additionally, we investigated the effect an experimental model using curdlan-injected SKG mice. Following curdlan injection, mice were orally administered...
Few studies have reported the epidemiology of lateral epicondylitis (LE) and medial (ME) in nationwide databases. This study aimed to investigate LE ME South Korea. We analyzed data from database Korean Health Insurance Review Assessment Service 2013 2017. investigated incidence, prevalence, surgical trends patients with or ME. Between 2017, we identified 2813,431 836,610 ME, respectively. were more frequently diagnosed women than men. During period, mean annual age-adjusted incidence rates...
This study compares ultrasound and surgical findings of anatomical variations in de Quervain's disease. Seventy-four wrists from patients with unilateral disease were examined through ultrasonography surgery. Presence intracompartment septum, abductor pollicis longus (APL) slips, selective stenosis verified by both methods. Two orthopedic surgeons assessed for intra- interobserver reliability. Amongst 74 participants (43 women 31 men), 60.8% had a complete 31.1% an incomplete 8.1% no septum;...
We investigate label-free measurement of molecular distribution by super-resolved Raman microscopy using surface plasmon (SP) localization. Localized SP was formed with plasmonic nanopost arrays (PNAs) for the in HeLa cells. Compared conventional on gold thin films, PNAs induce a localized near-field, which allows enhancement peak signal-to-noise ratio as much 4.5 dB shifts. Super-resolved distributions aromatic amino acids and lipids (C-C stretching C-H2 twist mode) targets cells were...
To assess the incidence rate of carpal tunnel syndrome (CTS) in patients with rheumatoid arthritis (RA) and investigate correlations between CTS disease activity duration RA.This retrospective cohort study was conducted to 1070 RA who had visited our rheumatism center March 2001 May 2013, participated follow-up at least once over a 5-year period. We also investigated C-reactive protein (CRP) levels time occurrence identify RA, RA.The cumulative for 12 years 6.8% (12/176), 37 cases occurred...
