The predictive roles of dihydropyrimidine dehydrogenase (DPD) in patients who undergo curative resection and adjuvant chemotherapy with S-1, which is the oral 5-fluorouracil prodrug tegafur combined with oteracil and gimeracil, remain unclear. In the present study, the clinical data from 66 consecutive patients who underwent curative resection and received adjuvant chemotherapy with S-1 for the...
BACKGROUND Patients with depersonalization disorder (DPD) typically complain about emotional detachment. Previous studies found reduced autonomic responsiveness to emotional stimuli for DPD patients as compared to patients with anxiety disorders. We aimed to investigate autonomic responsiveness to emotional auditory stimuli of DPD patients as compared to patient controls. Furthermore, we examin...
BACKGROUND A highly specific antibody against recombinant human dihydropyrimidine dehydrogenase (DPD) has been developed to immunohistochemically assess DPD expression in tumors. A new oral DPD inhibitory fluoropyrimidine (DIF), S-1, is reportedly effective against gastric scirrhous carcinoma. PATIENTS AND METHODS In this study, the relationship between immunoreactivity to DPD in biopsy speci...
Measurement of biochemical bone markers is commonly used in the management of various metabolic bone diseases (1, 2). The pyridinium crosslinks pyridinoline (PYD) and deoxypyridinoline (DPD) are well-characterized markers for bone resorption that have been available for several years (3 ). Assays to measure the sum of free and peptide-bound urinary PYD or DPD (total PYD or DPD) or free, non-pep...
background: statins have been effective medications in lowering serum total cholesterol (tc) concentrations across populations over time. the aim of this study was to estimate national and provincial trends in atorvastatin sales in iran, to systematically quantify its relationship with socio-economic indicators, and changes in tc level. methods : in this retrospective ecological study, conduc...
ترکیب جدید (n2,n6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide(dpd 2-نیتروژن، 6-نیتروژن دی (تیازول-2-ایل) پیریدین-2 و 6-دی کربوکسیلامید با استفاده از واکنش بین 2-آمینوتی ازول و پیریدین دی کربوکسیلیک اسید سنتز شد. ساختار dpd با تجزیه عنصری، طیف سنجی فروسرخ (ft-ir) و رزونانس مغناطیسی هسته (1hnmr) بررسی و تأیید شد. قابلیت حذف یون های فلزات سنگین (cd2+ و zn2+) از محلول، با dpd مورد مطالعه قرار گرفت. ...

BACKGROUND Thymidine phosphorylase (TP) is a key enzyme involved in pyrimidine nucleoside metabolism. Dihydropyrimidine dehydrogenase (DPD) is the major catabolic enzyme of 5-fluorouracil (5-FU). These are important enzymes in the pyrimidine salvage pathway and are considered to be key enzymes for determining the prognosis of patients with gastrointestinal cancer. In the present study, TP and D...
AIM Dihydropyrimidine dehydrogenase (DPD) deficiency can lead to severe toxicity following 5-fluorouracil (5FU) or capecitabine (CAP) treatment. Uracil (U) can be used as a probe to determine systemic DPD activity. The present study was performed to assess the sensitivity and specificity of a U loading dose for detecting DPD deficiency. METHODS Cancer patients with Common Toxicity Score (CTC)...
We investigated the correlation between tumor sensitivity to 5-fluorouracil (5-FU) and the enzymatic activity and mRNA levels of thymidylate synthetase (TS) and dihydropyrimidine dehydrogenase (DPD) using human tumor xenografts in nude mice. Three gastric carcinoma xenografts (SC-1-NU, St-4, and H-111), two colon carcinoma xenografts (Co-4 and Col-3-JCK), one pancreatic carcinoma xenograft (PAN...
