Abstract XIAP directly inhibits executor caspases, making it the most downstream antiapoptotic molecule. Here, we examined expression and function of in normal urothelium TCC. We also therapeutic effect xiap AS PODN on cell cycle apoptosis multidrug‐resistant T24 bladder cancer cells. was moderately expressed transitional epithelium with prominent superficial layer Seventy‐nine 108 (73.15%) tumor samples were positive for protein, but positivity not correlated stage or grade. Moreover, 4...

The death receptor Fas (Apo1/CD95) and ligand (FasL) system is recognised as a major pathway for the induction of apoptosis in vivo, antiapoptosis via its blockade plays critical role carcinogenesis progression several malignancies. However, function Fas–FasL urothelial cancer (UC) has not been elucidated. We therefore investigated expression Fas, FasL Decoy 3 (DcR3) UC specimens cell lines, examined cytotoxic effect an anti-Fas-activating monoclonal antibody (mAb) vitro. Immunohistochemical...

To determine whether lectin-like oxidized low-density lipoprotein (ox-LDL) receptor 1 (LOX-1) and the soluble form of LOX-1 (sLOX-1) are novel target molecules for diagnosis treatment rheumatoid arthritis (RA).Expression ox-LDL proteins in human RA synovium was evaluated by immunohistochemistry. Human fibroblast-like synoviocytes (FLS) were assessed ox-LDL-induced expression production matrix metalloproteinase (MMP-1) MMP-3. Levels sLOX-1 plasma synovial fluid patients with RA, compared...

The hingeless plastic ankle-foot orthosis (AFO) changes stiffness largely depending on how much is trimmed around the ankle. To support proper selection of and final adjustment orthotic stiffness, correlation between posterior upright width resistance to dorsi- plantar flexion movements was measured in 30 posterior-type AFOs. varied by regularly trimming ankle nine stages. bending AFOs 15d` with measuring device described Part 1. All decreased their both proportion reduction width. maximum...

Abstract Caspases exist as zymogens, and are activated by various extracellular stimuli, leading to apoptosis. One such stimulus is Fas/CD95, a member of the tumor necrosis factor receptor family, providing one means cytotoxic T lymphocyte (CTL)‐mediated cell lysis. Clinical evidence has shown that administration cytokine leads regression in selected patients with renal carcinomas (RCCs). Interferon‐γ (IFN‐γ) indicates its contribution anti‐tumor activity immune cells. IFN‐γ elicits effect...

Stromal cell-derived factor 1 (SDF-1/CXCL12/PBSF) plays important roles in the biological and physiological functions of haematopoietic mesenchymal stem cells. This chemokine regulates formation multiple organ systems during embryogenesis. However, its skeletal development remain unclear. Here we investigated SDF-1 chondrocyte differentiation. We demonstrated that protein was expressed at pre-hypertrophic hypertrophic chondrocytes newly formed endochondral callus rib fracture as well growth...

Twelve different prosthetic feet were tested by 10 male subjects with right below-knee amputations. Level walking each foot was investigated using a pair of force plates. Five parameters selected to compare the functional characteristics feet: 1) step length, 2) velocity on sound side in relation side, 3) depth valley pattern vertical component floor reaction force, 4) efficiency deceleration and acceleration foot, 5) irregular patterns wave form fore aft components force.

For paraplegics, two major disadvantages of hip-knee-ankle-foot orthotic systems that have a medial single hip joint are the short stride and horizontal rotation pelvis. The authors consider pelvic is caused by factors; one lack mechanism to assist flexion, other fixed ankle joints cause instability when step length becomes longer. Users must rotate their pelvis initiate swing in legs achieve stability making as parallel possible order avoid losing balance. To overcome those disadvantages,...

Previous research has shown that low-frequency repetitive transcranial magnetic stimulation over the primary motor area and supplementary can reduce L-dopa-induced dyskinesias in Parkinson's disease; however, it involved only patients with peak-dose or diphasic dyskinesia. We report a case of patient severely painful off-period dystonia unilateral lower limb who underwent 0.9-Hz subthreshold contralateral area. Repetitive significantly reduced walking disturbances but did not. The cortical...

Abstract The treatment for lymph node involvement (LNI) after radical prostatectomy (RP) has not been established. This study aimed to reveal the outcomes of various management strategies among patients with LNI RP. Retrospectively, 561 pelvic dissection (PLND) RP treated between 2006 and 2019 at 33 institutions participating in Japanese Urological Oncology Group were investigated. Metastasis‐free survival (MFS) was primary outcome. Patients stratified by prostate‐specific antigen (PSA)...

A device was developed to measure the dorsi- and plantar flexion moment of plastic ankle-foot orthoses when deflected. It is operated by manually controlling a lever which used apply nearly static force. Various can be classified according characteristics correcting force measured this device. Simplicity high reproducibility are major advantages. However, obtain measurements approximating under wearing conditions its use restricted made low-viscosity materials.

To assess the utility, safety and feasibility of laparoscopic adrenalectomy (LA) for pheochromocytoma. We reviewed our experience, focusing on surgical outcomes compared with historical open (OA) modifications in procedures.Between 1997 2007, 23 patients pheochromocytoma underwent LA at institution. As controls, 18 undergoing OA were examined retrospectively. In first cases LA, we used an abdominal wall-lifting device low pneumoperitoneal pressure initial ligation adrenal vein. subsequent...

Transrectal ultrasound (TRUS) guided prostate biopsy is standard diagnostic procedure for cancer (PCa). However, possibility of dissemination cells by not negligible. To investigate this possibility, we examined specific antigen (PSA)-bearing in peripheral blood the 108 patients before and after biopsy. Peripheral samples were obtained from with elevated serum PSA (sPSA) levels, who had undergone sextant using TRUS. The presence PSA-mRNA bearing was nested RT-PCR method enabling detection...
