The dependence of the critical current density Jc on hydrostatic pressure to 0.6 GPa is determined for a single 25 degrees [001]-tilt grain boundary in a bicrystalline ring of nearly optimally doped melt-textured YBa2Cu3Ox. Jc is found to increase rapidly under pressure at +20%/GPa. A new diagnostic method is introduced (pressure-induced Jc relaxation)(More)
BACKGROUND/AIMS Autophagic cell death has recently been implicated in the pathophysiology of tendinopathy. Prostaglandin E2 (PGE2), a known inflammatory mediator of tendinitis, inhibits tenofibroblast proliferation in vitro; however, the underlying mechanism is unclear. The present study investigated the relationship between PGE2 production and autophagic(More)
Stem cells have long been hypothesized to improve outcomes following rotator cuff repair. However, these cells must be signaled in order to do so. TGIF1 is a transcription factor that has been found to be down-regulated in cells involved in chondrogenesis. We therefore wished to examine whether stem cells expressing lower levels of TGIF1 could better(More)
BACKGROUND/AIMS The slow healing process of tendon-to-bone junctions can be accelerated via implanted tendon-derived stem cells (TDSCs) with silenced transforming growth interacting factor 1 (TGIF1) gene. Tendon-to-bone insertion site is the special form of connective tissues derivatives of common connective progenitors, where TGF-β plays bidirectional(More)
OBJECTIVES To investigate the effectiveness of intermittent pneumatic compression (IPC) devices combined with anticoagulants for the prevention of deep vein thrombosis (DVT) after total knee arthroplasty (TKA). PATIENTS AND METHODS In total 120 patients were involved in this pilot study. Patients in the control group received 10 mg of rivaroxaban per day(More)
The asymmetric unit of the title compound, {[Eu(C(7)H(3)NO(4))Cl(CH(3)OH)(2)]·CH(3)OH}(n), contains one Eu(III) ion, one pyridine 2,3-dicarboxylate dianion (PDC), two CH(3)OH mol-ecules coordinating to the metal atom, one coordinating chloride and one lattice occluded CH(3)OH mol-ecule. In the crystal, each PDC anion coordinates to three adjacent Eu(III)(More)
Hyaluronic acid fillers are used to improve the appearance of nasolabial folds (NLF). This study aimed to compare the efficacy, safety, and durability of a new hyaluronic acid gel (BioHyalux) versus Restylane for the correction of NLF. This was a multicenter, double-blinded, randomized, controlled, non-inferiority clinical trial involving 88 subjects with(More)
BACKGROUND The aim of this study was to identify whether iliac vein compression syndrome (IVCS) is a risk factor for left-sided deep venous thrombosis (DVT) in hip fracture patients and the influence IVCS may have on the treatment of DVT. MATERIAL AND METHODS A retrospective study was carried out among 424 hip fracture patients admitted to our hospital from(More)
To evaluate the effect of leptin combined with CoCl2 on rat femur fracture healing. 48 male Sprague Dawley rats were randomly divided into two main groups. Then standardized femur fractures were created to all rats. Control group rats were treated with 0.5 mL physiological saline, and experimental group rats were treated with 5 μg/Kg.d leptin and 15 mg/Kg.d(More)
BACKGROUND The aim of this study was to evaluate the safety and clinical outcome of primary total knee arthroplasty in patients with diabetes mellitus. MATERIAL AND METHODS Among the patients who were treated with total knee arthroplasty, there were 98 patients (116 knees) associated with diabetes. Osteoarthritis was diagnosed in 90 patients and rheumatoid(More)
