Transport of Ag(i), Cd(ii), Co(ii), Cu(ii), Ni(ii), Pb(ii) and Zn(ii) cations across a bulk liquid membrane (BLM) containing N,N′-dibenzyl-N′′-(2,2,2-trifluoroacetyl)-phosphoric triamide (PTC) as a new carrier is studied by atomic absorption spectrometry. The results show selective and efficient transport of the copper(ii) cation from aqueous solution in the presence of the other cations. Various factors are optimized in order to obtain maximum transport efficiency. The PTC ligand is characterized by single crystal X-ray diffraction analysis, IR, NMR (19F, 31P, 1H, 13C) and mass spectroscopy. The complex formation reaction between copper(ii) and PTC is studied by a conductometric method, which shows the 1 : 1 stoichiometry for ligand and copper(ii).Selective transport of Cu(ii) cation in the presence of six other cations across a bulk liquid membrane containing a novel phosphoric triamide carrier is studied. 相似文献

Background
Sternal wound infection (SWI) is an uncommon but potentially life-threatening complication of cardiac surgery. Predisposing factors for SWI are multiple with varied frequencies in different studies. The purpose of this study was to assess the incidence, risk factors, and mortality of SWI after coronary artery bypass grafting (CABG) at Tehran Heart Center. 相似文献35.

OBJECTIVE: The objective of this study was to examine the impact of introducing rosuvastatin calcium on direct and indirect costs among patients at high risk for coronary heart disease. METHODS: An economic simulation model was developed to project the number of cardiovascular events and associated direct and indirect costs under varying treatment scenarios. RESULTS: In an average-sized commercial health plan with 210,000 covered lives and 9,336 high-risk patients, an uptake of rosuvastatin by 11% of high-risk patients would result in eight fewer cardiovascular events, a net savings of 0.85 million dollars in direct medical costs and a net savings of 36,404 dollars in productivity loss over a period of 5 years. The overall reduction in total costs is equivalent to 1735 dollars per rosuvastatin-treated patient. CONCLUSIONS: At current statin prices, the use of rosuvastatin could lead to fewer cardiovascular events and lower direct and indirect costs. 相似文献

ObjectiveTo evaluate the preventive effect of neonatal circumcision on urinary tract infection and the incidence of complications following neonatal circumcision using Plastibell.Materials and methodsA prospective study was carried out between 2004 and 2008. During this period, there were 3000 neonatal circumcisions. All of the cases were examined for any complications 1 week later, and occurrence of meatal stenosis was followed up to 15 months of age. In this group, urine analysis and culture was successfully performed four times for 2000 circumcised infants at 1.5, 3, 9 and 15 months. In the control group of 3000 uncircumcised infants, 1000 cases accomplished urine analysis and culture at the same designated intervals.ResultsA positive urine culture was observed in none of the circumcised cases and in 20 (2%) uncircumcised cases after obtaining a suprapubic bladder aspiration sample. The latter 20 infants were circumcised and follow-up cultures were negative in 17 cases. The overall complication rate in the circumcised group was 1.6%. The difference in frequency of urinary tract infection between the two groups was statistically significant (P < 0.0001).ConclusionNeonatal circumcision has few complications and reduces the incidence of asymptomatic urinary infection. It may be considered as a preventative health measure. 相似文献

The Calmette-Güerin vaccine (BCG) is administered to all the newborns in Iran in order to prevent tuberculosis. Complications of this vaccine are uncommon. We report disseminated BCG disease in 17 patients less than 10 years old. This is a retrospective study of total of 17 cases who were admitted in Children Medical Center Hospital with systemic syndrome compatible with Mycobacterium disease with evidence of histopathologic demonstration of acid-fast bacilli during 1995-2004. Fourteen cases occurred in children younger than 1 year old. Nine patients were female. Ten of the 17 total cases were associated with an immune deficiency including severe combined immunodeficiency, chronic granulomatous disease and cell mediated immune defect. Response to therapy was ineffective and 10 of them (58.8%) died. Disseminated BCG disease is an uncommon but devastating complication of vaccination that should be considered in the appropriate clinical setting. Immune-compromised infants are at greatest risk and they respond poorly to standard therapies. 相似文献

Endometrial stromal sarcomas (ESS) are the second most common uterine sarcomas. Endometrial stromal sarcomas account for 0.25% of all uterine malignancies. Uterine sarcomas most often affect postmenopausal women. The aim of this retrospective study was to review the experience in the treatment and clinical outcome of low grade malignant endometrial stromal sarcoma. Seventeen patients with histologically proven low grade ESS in department of Gynecologic Oncology of the Vali-e-Asr Hospital, Tehran-Iran, between 1999 and 2008 were included in the analysis. Demographics, pathology, treatment, time to recurrence, salvage therapy and survival information was collected. The median age of our patients was 45.35 ± 6.8 (range 36-61). The median parity of the patients was 5 (range 0-8). Most patients were diagnosed at FIGO stage I. The mean survival for patients with stage I and II was 73.5 ± 35.09 and 57.6 ± 5.37 months, respectively, with mortality rate of 5.9% through a median follow-up time of 68.82 ± 30 months. Of 17 patients, seven cases (35.29%) were disease free at 6 years after hysterectomy. Radiotherapy was administered to four patients (23.53%). Only one patient recurred at 10th month after surgery. Surgeries not preserving ovarian function were helpful to decrease the risk of recurrence compared with those sparing ovarian function. 相似文献
