Abstract Recent studies have shown that genetic effects on bone mineral density (BMD) and turnover are related to allelic variation in the vitamin D receptor (VDR) gene. We examined influences of VDR gene 202 normal healthy premenopausal Japanese women (age 30.1 ± 1.2, mean SEM). The effect BMD is similar observed Caucasian women; however, there major differences allele frequency. B by Bsm I restriction fragment length polymorphisms (RFLPs), associated with low high turnover, found only 12%...

The fracture toughness of a variety dental composites was evaluated using notched bending specimens, with and without pre-cracks. pre-crack simulates more accurately sharp, natural flaw in material than does notch, is standard procedure fracture-toughness evaluation. related to the filler composition degree conversion composite resins. In general, highest heavily filled resins, independent matrix. results also show that producing certain reduced value their compared notched-only specimens.

To study distribution and patterns of nerve hypertrophy in chronic inflammatory demyelinating polyneuropathy (CIDP), magnetic resonance neurography with 3-dimensional reconstruction short tau inversion recovery images was performed 33 patients. This technique clearly showed longitudinal morphological changes from the cervical roots to trunks proximal arm. Nerve enlargement detected 88% According clinical subtype CIDP, typical CIDP patients symmetric root-dominant hypertrophy, whereas...

We studied the influence of erythropoietin (EPO) treatment on hemoglobin A1c (HbA1c) levels under conditions which eliminate effect changes in blood glucose concentration. HbA1c levels, glucose, hematocrit (Hct) and reticulocyte counts were serially measured every two weeks after starting or stopping EPO administration 15 non-diabetic hemodialysis patients. significantly influenced more erythropoiesis fluctuated by changing dose EPO, changed, though there no significant during study period....

Glycated albumin (GA), which is an alternative glycemic marker, influenced by factors associated with turnover, and it not clear whether proteinuria influences GA values in diabetic patients chronic kidney disease (CKD).We enrolled 94 CKD stages 3 to 5. GA, glycated hemoglobin, urinary protein excretion (UP) levels were consecutively obtained each patient. The correlations between UP those changes examined.There was a significant correlation all cases (r=-0.46, p<0.0001), however no found of...

Although sarcoid-like reactions are uncommon in colorectal cancer, they can coexist with other cancers. We herein report a 50-year-old woman sigmoid adenocarcinoma and osseous that resembled metastases. Positron emission tomography-computed tomography revealed an uptake the iliac bone para-aortic lymph nodes. The depth of invasion indicates non-metastatic lesions. Bone node biopsies epithelioid non-caseating granulomas trabeculae, resulting final diagnosis pathological T2N2aM0, Stage IIIB....

The compressive yield strength and creep of 21 dental composite resins were evaluated correlated with filler volume percent extent cure in the resin. In general, composites more dependent upon fraction than on cure. However, types monomers fillers used formulation appeared to play a major role determining characteristics materials.

Summary Alcohol‐induced osteonecrosis of the femoral head ( ONFH ) is observed in alcohol abusers and patients with alcoholic fatty liver disease. It has been reported that Toll‐like receptor 4 TLR 4) signalling plays a crucial role pathogenesis We previously corticosteroid‐induced rat model, suggested contributes to . Thus, it thought alcohol‐induced probably similar The aim this study was develop new animal model for evaluate relationship between pro‐inflammatory response via TLRs...

The aim of this study was to clarify clinicopathological features, frequencies molecular biomarkers, and prognoses in Japanese colorectal cancer patients compare them with right-sided colon (RCC) left-sided (LCRC).We consecutively selected 575 who underwent surgical resection from 2008 2011. RCC located the cecum transverse colon, LCRC splenic flexure rectum. Frequencies KRAS gene mutation, BRAF microsatellite instability (MSI), l18qLOH CpG island methylator phenotype (CIMP) were...

Density gradient centrifugation (DGC) and swim-up techniques have been reported for semen preparation in assisted reproductive humans. We investigated whether using a combination of DGC could effectively decrease morphologically abnormal human sperms at the ultrastructural level. Semen samples were obtained from 16 infertile males fractionated by following DGC. Ultrastructural abnormalities original semen, lower layer DGC, upper analyzed transmission electron microscopy. The correlation...

Abstract Background Advanced surgical interventions are required to treat malignancies in the anterior skull base (ASB). This study investigates utility of endoscopic endonasal and transcranial surgery (EETS) using a high‐definition three‐dimensional exoscope as an alternative traditional microscopy. Methods Six patients with carcinomas varying histopathologies underwent employing EETS maneuver, which synchronized three distinct modalities: harvesting anterolateral thigh flap, initiation...
