This study was carried out to estimate the relationship between hand length, foot length and stature using multiple linear regression analyses based on a sample of male and female adult Turks residing in Adana. Measurements of hand length, foot length and stature were taken from 155 adult Turks (80 male, 75 female) aged 17-23 years. The participants were students of the Medical Faculty of Cukurova University. A multiple linear regression model was fitted to the observed data. Stature was taken as the response or dependent variable, hand length and foot length were taken as explanatory variables or regressors. All possible (simple and multiple) linear regression models for each of males, females and both genders together were tested for the best model. The multiple linear regression model for both genders together was found to be the best model with the highest values for the coefficients of determination R2 = 0.861 and R2adjusted = 0.859, and multiple correlation coefficient R = 0.928. 相似文献
The role of survivin that regulates the biological behavior of non-small-cell lung carcinoma (NSCLC) is still controversial. We aimed to investigate survivin expression in NSCLC and to define any correlation with expressions of p53, bcl-2, bax, apoptotic index (AI), tumor cell proliferation, clinicopathologic variables, and overall survival. Tumors of 63 patients with NSCLC were examined for expressions of survivin, p53, bcl-2, bax, and Ki-67 by immunohistochemistry. AI was also evaluated. Results for each antibody were correlated with each other, and with clinicopathologic variables including age, sex, histologic subtype, TNM (T: primary tumor, N: regional lymph node metastasis, M: distant metastasis) stage, lymph node status, smoking history, and prognosis. Nuclear survivin expression was inversely correlated with p53 expression (P = 0.04, r = - 0.367), and tumor stage (P = 0.03, r = - 0.273), and positively correlated with tumor cell proliferation (P = 0.009, r = 0.329). Cytoplasmic survivin expression positively correlated with smoking history (P = 0.02, r = 0.282). Survivin/bax ratio was inversely correlated with AI (r: - 0.004). By Kaplan-Meier analysis, TNM stage (P < or = 0.001), lymph node metastasis (P = 0.04), and Ki-67 index (P < or = 0.001) were associated with survival, whereas survivin was not. In multivariate analysis, only TNM stage was an independent predictor. Although survivin and other apoptosis-related protein expressions fail to predict the clinical outcome, the present findings suggest that survivin is involved in tumor cell apoptosis and proliferation and may play a role in critical steps of cancer progression in NSCLC. 相似文献
This study aims to synthesize and characterize an economical and ecological adsorbent with high adsorption capacity. For this purpose, the peanut shells (Pistacia vera L.) were modified chemically. After the synthesis of activated carbon (AC), the optimum conditions for enrichment steps were performed using parameters: pH and contact time for uranium in the model solutions. The measurements were carried out by inductively coupled plasma-mass spectrometry (ICP-MS). From the shapes of the BET isotherms, the AC obtained exhibits type I. The study indicated that the surface area and total pore volume of the AC were found to be 679.9 m2 g−1 and 0.31 cc g−1, respectively. The adsorption capacity was found to be 260 mg g−1. The optimum pH was found to be 6.0 for enrichment using the AC obtained by sulfuric acid as a chemical-modifier. The optimized method was applied to enrichment of U at ppb levels in the model solutions.
To investigate the factors affecting primary bladder closure in cloacal exstrophy (CE). A successful primary closure is important for optimizing reconstructive outcomes, and it is a critical first-step in the reconstruction of CE. The authors' hypothesize that a smaller diastasis and use of an osteotomy are independent predictors of a successful closure.
Methods
A prospectively maintained database of 1332 exstrophy-epispadias complex (EEC) patients was reviewed for CE patients closed between 1975 and 2015. Univariate and multivariable analyses were performed to identify significant factors associated with CE primary bladder closure.
Results
Of 143?CE patients identified, 99 patients met inclusion criteria. Median follow-up time was 8.82 [IQR 5.43–14.26] years. In the multivariable model, the odds of having a successful closure are about 4 times greater for the staged cloacal approach compared to the 1-stage approach (OR, 3.7; 95% CI 1.2–11.5; p-value?=?0.023). Also, having an osteotomy increases the chance of a successful closure by almost six-fold (OR, 5.8; 95% CI 1.7–19.6; p-value?=?0.004).
Conclusions
Using the staged approach with a pelvic osteotomy is paramount to a successful primary closure in CE. The authors strongly recommend using the staged approach and osteotomy as these factors independently increase the chance for a successful primary bladder closure.
Summary The authors report four patients with intracranial hydatic cysts. One patient had a pontine lesion which was punctured and aspirated and the cyst wall removed with a satisfactory outcome. The second patient had multiple cysts which was comparable to meningeomatosis. She had a rapidly deteriorating neurologic condition which proved to be fatal in spite of two consecutive surgical interventions. The third patient had nine lesions although only six were evident on the MRI. All of the cysts were removed, while two cysts ruptured. Multiple paracardial cysts of this patient were surgically removed shortly after the craniotomy. The last patient, again with multiple intracranial hydatid cysts had safe, total removal of all cysts. The first postoperative control CT raised the possibility of recurrence since the CT was highly suggestive of a hydatid cyst. However, this was not confirmed in the follow-up CT examination. Problems and the solutions of management are discussed.
Zusammenfassung Die Autoren berichten über vier Fälle mit intrakraniellen Echinococcus-Zysten. Eine Patientin hatte eine Brückenläsion, die durch Punktion und Aspiration des Zysteninhaltes mit Entfernung der Zystenwand behandelt wurde. Die zweite Patientin wies multiple Zysten auf, die mit einer Meningomatose vergleichbar waren. Trotz zweier chirurgischer Interventionen kam es zur raschen neurologischen Verschlechterung mit tödlichem Ausgang. Der dritte Patient hatte neun Herde, von denen sich im Kernspintomogramm nur sechs darstellten. Alle Zysten wurden entfernt. Bei zwei Zysten kam es zur Ruptur. Kurz nach der Kraniotomie wurden bei diesem Patienten multiple parakardiale Zysten chirurgisch entfernt. Bei der vierten Patientin bestanden ebenfalls multiple intrakranielle Echinococcus-Zysten, die alle sicher exstirpiert werden konnten. Beim ersten postoperativen Kontroll-CT bestand aufgrund der zystenähnlichen Strukturen Verdacht auf ein Rezidiv, der sich bei der Wiederholungsuntersuchung jedoch nicht bestätigte. Probleme und therapeutisches Management werden diskutiert.
