از آنجا که اجرای برنامه خصوصیسازی از طریق عرضه عمومی سهام شرکتهای دولتی در بورس میتواند نقدشوندگی بازار را تحت تاثیر قرار دهد، پژوهش حاضر درصدد بررسی اثرات اجرای این برنامه بر نقدشوندگی بورس اوراق بهادار تهران میباشد و توسعه بلندمدت را ارزیابی میکند. دوره زمانی این پژوهش از ابتدای سال 84 تا ششماه نخست سال 92 (34 مشاهده فصلی) میباشد که در نهایت تعداد 2516 داده جمعآوری گردید. به منظور افز...
The present study assesses the effects of neo-adjuvant chemotherapy (NAC) with uracil and tegafur (UFT) alone vs UFT plus cyclophosphamide (CPA), on the activity of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) in breast cancer tissues. Breast cancer patients were randomly assigned to 3 groups; the control (no-treatment) group (n=13), the UFT (5-8 mg/kg/day) alone group (n...
BACKGROUND AND AIM Depressive pseudodementia (DPD) is a condition which may develop secondary to depression. The aim of this study was to contribute to the differential diagnosis between Alzheimer disease (AD) and DPD by comparing the neurocognitive tests and hippocampal volume. MATERIALS AND METHODS Patients who met criteria of AD/DPD were enrolled in the study. All patients were assessed us...
BACKGROUND AND PURPOSE Depression occurs frequently in PD; however the neural basis of depression in PD remains unclear. The aim of this study was to characterize possible depression-related white matter microstructural changes in the thalamus of patients with DPD compared with those with NDPD. MATERIALS AND METHODS FA and MD maps from DTI were obtained in 14 patients with DPD and 18 patients...
This paper examines different linearization techniques which are used to linearize the power amplifier by emphasizing on weakness and strength of each technique. After complete analyze it has been concluded that Digital Pre Distortion (DPD) technique is the best linearization technique to linearize the power amplifier. DPD technique for linearizing a wideband radio frequency power amplifier has...
The H(2)F(3)(-) anion in mononuclear [Cu(dpd)(2)][(H(2)F(3))(2)] (dpd = di-2-pyridyl-methanediol) exists as a HF(2)(-)/HF adduct as evidenced by infrared spectroscopy and X-ray crystallography.
افزایش تقاضای استفاده از آب باعث افزایش رقابت بر سر منابع محدود آب گردیده است. مدل های بهینه سازی موجود نیز قادر به ارائه راه حلی برای این مسائل نیستند. در سال های اخیر به منظور اعمال یک مدیریت کارآتر که رقابت در مصرف را در نظر بگیرد، تعداد محدودی مدل های بازی پویای تصادفی گسسته ارائه گردیده اند. این مدل ها عمدتاً مدیریت توزیع آب منطقی و کارا را ارائه می دهند، اما عملیات محاسباتی پیچیده و حجیمی ...
Dihydropyrimidine dehydrogenase (DPD) is the initial, rate-limiting enzyme in the catabolism of 5-fluorouracil (5-FU). DPD has an important role in regulating the availability of 5-FU for anabolism. It is now clear that DPD also accounts for much of the variability observed with the therapeutic use of 5-FU, including variable drug levels during 24-hour infusion, erratic pharmacokinetics, variab...
5-Fluorouracil (5-FU) is used widely in the treatment of several common neoplasms. Dihydropyrimidine dehydrogenase (DPD) is the initial and rate-limiting enzyme in the catabolism of 5-FU. Several recent studies have described a pharmacogenetic disorder in which cancer patients with decreased DPD activity develop life-threatening toxicity following exposure to 5-FU. We reported recently the firs...
Bone metastasis is common in lung cancer patient and the diagnosis of bone metastasis is usually made by using imaging techniques, especially bone scintigraphy. However, the diagnostic yield from bone scintigraphy is limited. The aim of this study is to assess the clinical usefulness of urinary pyridinoline cross-linked N-telopeptides of Type I collagen (NTx), urinary deoxypyridinoline (DPD), a...
