We have investigated low Reynolds number flow past single dissipative-particle-dynamics particles (point centers of repulsion), their clusters, and their filaments using dissipative-particle-dynamics (DPD) simulations. The objective of our study was to verify whether DPD particles immersed in a sea of DPD particles behave like Langevin particles suspended in a continuous Newtonian fluid solvent...
Dihydropyrimidine dehydrogenase (DPD) activity could be affected by single nucleotide polymorphisms (SNPs), resulting in either no effect, partial or complete loss of DPD activity. To evaluate if SNPs of DPD can be used to predict 5-FU toxicity, we evaluated five SNPs of DPD (14G1A, G1156T, G2194A, T85C and T464A) by TaqMan real time PCR in 60 colorectal cancer patients. Clinical data demonstra...
A cognitive-behavioural model of depersonalisation disorder (DPD) suggests that catastrophic attributions and appraisals, and increased attention to symptoms, play important roles in the development and maintenance of the disorder. Empirical testing of this model was investigated in three groups: 25 patients with DPD, 21 patients with anxiety (obsessive-compulsive or panic disorder), and 22 psy...
BACKGROUND AND OBJECTIVES The reliability and usefulness of the right ventricular (RV) Tei index (RTX) remains controversial because it has not been possible to simultaneously measure RV inflow and outflow. However, dual pulsed-wave Doppler (DPD) enables flow velocities to be obtained at different sampling sites simultaneously. In this study we evaluated the feasibility and reliability of RTX v...
Background and purpose: 5-Flourouracil (5-FU) is one of the most common chemical drugs used in chemotherapy of patients with cancers. Dihydropyrimidine dehydrogenase (DPD) is a critical enzyme in the catabolism of 5-FU. More than 80% of the administered 5-FU is catabolized by DPD. c.1905+1G>A mutation on DPD gene is the most important mutation associated with DPD enzymatic deficiency which lead...
Radiosonde humidity records represent the only in situ observations of tropospheric water vapor content with multidecadal length and quasi-global coverage. However, their use has been hampered by ubiquitous and large discontinuities resulting from changes to instrumentation and observing practices. Here a new approach is developed to homogenize historical records of tropospheric (up to 100 hPa)...
PURPOSE To investigate a rationale of pancreatobiliary cancers, thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) concentrations in cancer tissues were evaluated. PATIENTS AND METHODS Twenty-nine patients with pancreatic cancer (PC) and 43 with biliary tract cancer (BTC; 27 cases of bile duct cancer, 8 of gallbladder cancer and 8 of cancer of the papillary area) were include...
Dihydropyrimidine dehydrogenase (DPD) is the initial, rate-limiting enzyme in the catabolism of 5-fluorouracil, one of the most widely used cancer chemotherapeutic agents. Previous studies have demonstrated the clinical importance of determination of DPD in cancer patients, suggesting that the efficacy and toxicity of 5-fluorouracil may directly relate to the DPD activity in both tumor and host...
Dihydropyrimidine dehydrogenase (DPD) is the initial key enzyme in the catabolism of 5-fluorouracil (5-FU). We measured DPD activity in lymphocytes from 57 consecutive head and neck cancer patients while simultaneously monitoring 5-FU pharmacokinetics during 5-day, continuous infusion (1000 mg/m2/day) 5-FU therapy (82 cycles in total). The mean value for DPD activity was 0.186 +/- 0.068 (SD) nm...
BACKGROUND The enzyme dihydropyrimidine dehydrogenase (DPD) is involved in the metabolism of 5-fluorouracil (5-FU). The aim of this study was to clarify the correlation between the expression of DPD and the efficacy of 5-FU therapy in patients with lung adenocarcinoma (AD). PATIENTS AND METHODS We examined surgically resected specimens from 90 stage I to IIIA patients with lung ADs to determi...
