BACKGROUND AND OBJECTIVE: The association between cigarette smoking and periodontitis was examined employing two nationally representative samples of adults in Japan. MATERIAL AND METHODS: Data were derived from the Survey of Dental Diseases (SDD) and the National Nutrition Survey (NNS) in 1999. In the SDD, periodontal conditions were evaluated by calibrated dentists utilizing the Community Periodontal Index (CPI), whereas in the NNS, participants were interviewed on the basis of smoking status by enumerators. Among 6805 records electronically linked via a household identification code, 4828 records of individuals aged 20 yr or older were analyzed. RESULTS: The prevalence of periodontal disease varied significantly by smoking status (p < 0.0001): 39.3%, 49.5% and 47.3% (CPI > or = 3), and 7.9%, 11.7% and 12.4% (a more severe form of periodontitis, CPI = 4), for nonsmokers, former smokers and current smokers, respectively. In adults aged > or = 40 yr (n = 3493), logistic regression models revealed greater probabilities (approximately 1.4 times higher) of periodontitis [CPI > or = 3, odds ratio = 1.38 (1.12-1.71), p = 0.0024] and a more severe form of periodontitis [odds ratio = 1.40 (1.04-1.89), p = 0.0288] in current smokers compared with nonsmokers, following adjustment for possible confounding factors. CONCLUSION: Based on the findings of this study and other numerous reports, cigarette smoking leads to deterioration of periodontal conditions in Japanese adults. 相似文献

Objectives
Renal cell carcinoma (RCC) is characterized by a propensity for extension into the renal vein and inferior vena cava (IVC) and is associated with poor prognosis. BAP1 mutation, which occurs in about 15% of patients with clear cell RCC (ccRCC), also predicts poor prognosis. The aim of this study was to elucidate the association between BAP1 protein expression and clinicopathological outcomes in patients with nonmetastatic ccRCC with an IVC tumor thrombus (IVCTT).Material and methods
Thirty-five patients with nonmetastatic ccRCC with an IVCTT who underwent radical nephrectomy and tumor thrombectomy at our institution from 1999 to 2010 were retrospectively evaluated. Immunohistochemical (IHC) analyses were performed for the expression of BAP1 protein, and the associations between the expression of BAP1 and clinical outcomes were assessed. Survival analyses were performed using the Kaplan-Meier method and log-rank test. Multivariate analyses of the associations between disease-free survival (DFS) and clinical variables including BAP1 protein expression, tumor size, Karnofsky performance status (KPS) score, and the extension level of the tumor thrombus were performed using a Cox proportional hazard model.Results
The median follow-up time was 58.8 months (range: 2–130 months). The median age was 68 years (range: 37–80 years). The median size of the primary tumor was 9.6 cm (range: 3.0–15.0 cm). The IVCTT extended above and below the diaphragm in 10 (28.6%) and 25 (71.4%) patients, respectively. The KPS score was>80 in 23 patients (65.7%). BAP1 protein expression on IHC was positive in 24 cases (68.8%) and negative in 11 cases (31.2%). The median overall survival in cases with BAP1-negative and -positive tumor on IHC staining were 44.7 and 81.5 months, respectively (P = 0.052). BAP1-negative tumor on IHC staining was associated with a significantly shorter DFS than BAP1-positive tumor (median DFS = 10.0 vs. 26.0 months, respectively; P = 0.011). Multivariate analysis showed that only BAP1-negative tumor on IHC staining was significantly associated with shorter DFS (P = 0.004).Conclusions
Patients whose tumors had loss of BAP1 protein expression were significantly associated with poor prognosis in patients with ccRCC with an IVCTT who underwent radical nephrectomy and tumor thrombectomy. 相似文献3.

In an attempt to develop a method to produce a cryoprecipitate with a predictable Factor VIII potency, several variables were studied and statistically analyzed. These included the hematocrit, age, blood group and Rh type of the donor; possible epinephrine release; the degree of lipemia, volume, pH and Factor VIII activity of the donor plasma; the volume of cryoprecipitates, its Factor VIII activity and the per cent yield; and the Factor VIII activity of the supernatant plasma. Cryoprecipitates were prepared by the method of Pool and Shannon from the plasmas of 40 random male donors, half the bloods being drawn in ACD and half in CPD. None of the variables had a significant influence on the per cent yield of activity, although the mean values obtained suggest that the per cent yield of Factor VIII activity in the cryoprecipitates prepared from CPD plasmas is higher than in those prepared from ACD plasma. Although the per cent yield of Factor VIII in cryoprecipitates prepared from CPD plasma is not significantly different from that of ACD plasma, the mean total units of Factor VIII activity is significantly higher in CPD cryoprecipitates. It also was confirmed that a higher per cent Factor VIII activity in the donor results in a relatively higher activity in the cryoprecipitate. The data indicate that if CPD plasma collected from donors having above a certain minimum per cent activity were used for cryoprecipitate production, one could be assured of having a minimum of 100 units of Factor VIII activity per bag. 相似文献

We have reported a rounded atelectasis in a 65-year-old man. On CT scan a pleural-based mass was associated with curved, ragged projections from the lower pole of the lesion. This phenomenon appears to be the counterpart of the so-called comet tail on regular tomography and, because of its clarity, may further facilitate the diagnosis of this entity. 相似文献

Mutations in the connexin26 gene (GJB2) are the most common genetic cause of congenital bilateral non-syndromic sensorineural hearing loss. Transgenic mice were established carrying human Cx26 with the R75W mutation that was identified in a deaf family with autosomal dominant negative inheritance [Kudo T et al. (2003) Hum Mol Genet 12:995–1004]. A dominant-negative Gjb2 R75W transgenic mouse model shows incomplete development of the cochlear supporting cells, resulting in profound deafness from birth [Inoshita A et al. (2008) Neuroscience 156:1039–1047]. The Cx26 defect in the Gjb2 R75W transgenic mouse is restricted to the supporting cells; it is unclear why the auditory response is severely disturbed in spite of the presence of outer hair cells (OHCs). The present study was designed to evaluate developmental changes in the in vivo and in vitro function of the OHC, and the fine structure of the OHC and adjacent supporting cells in the R75W transgenic mouse. No detectable distortion product otoacoustic emissions were observed at any frequencies in R75W transgenic mice throughout development. A characteristic phenotype observed in these mice was the absence of the tunnel of Corti, Nuel's space, and spaces surrounding the OHC; the OHC were compressed and squeezed by the surrounding supporting cells. On the other hand, the OHC developed normally. Structural features of the lateral wall, such as the membrane-bound subsurface cisterna beneath the plasma membrane, were intact. Prestin, the voltage-dependent motor protein, was observed by immunohistochemistry in the OHC basolateral membranes of both transgenic and non-transgenic mice. No significant differences in electromotility of isolated OHCs during development was observed between transgenic and control mice. The present study indicates that normal development of the supporting cells is indispensable for proper cellular function of the OHC. 相似文献
