cm jejunal segment proximal (n=6) and a 40 cm ileal segment distal (n=6) to a GCDC infusion port were measured. During GCDC infusion (60 pimoVmin) jejunal and ileal transit were markedly (p<005) delayed (31.6 (7.7), mean (SEM) v 14.5 (3.8) min and 37.0 (5.7) v 21-0 (3.5) min, respectively), segment volumes increased (141.1 (30.2) v 59.2 (9.9) ml and 173.2 (26.3) v 83.9 (9.5) ml; p<0 05), while ...

The aim of this study was to determine whether the changes in myocardial activation pattern resulting from acute stretching during ventricular fibrillation can be counteracted by administering a compound that blocks receptors sensitive to stretch. The study involved 16 isolated rabbit hearts, in which refractoriness and activation frequency during ventricular fibrillation were measured before, ...

have been used for more than 30 years for heat and moisture retention during general anesthesia. Studies about bacteriostatic vs nonbacteriostatic HMEs (BHMEs/ NHMEs) have been conducted to assess their role in preventing bacterial transmission to the anesthesia breathing circuit; none have been done on anesthetized patients in the operating room. The present study adds to existing knowledge ab...

In a prospective, randomized, parallel study, two regimens of platelet-suppressant therapy (PST)--dipyridamole-aspirin and pentoxifylline-aspirin--were compared with standard oral anticoagulation with warfarin in the prevention of prosthetic heart valve thromboembolism. In the entire group of 254 patients followed for 395.6 patient-years, the thromboembolic rate was significantly less in the wa...

Assurance cases provide a structured method of explaining why a system has some desired property, for example, that the system is safe. But there is no agreed approach for explaining what degree of confidence one should have in the conclusions of such a case. This report defines a new concept, eliminative argumentation, that provides a philosophically grounded basis for assessing how much confi...

The purpose was to determine the effect of personal and professional factors, as well as motivational orientations, on the participation of nursing staff in continuing education at two health institutions, one public and another private. Descriptive, comparative, correlational design. Probabilistic sampling, random estimation, error limit 0.05, confidence level 95%. Participants were 105 subjec...

BACKGROUND Sinus mucosa abnormalities on image studies, which is the major diagnostic measure for sinusitis, were investigated in patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). METHODS A retrospective review of the MRIs for patients with NPC was conducted. Sinus mucosa abnormalities were staged by the Lund-Mackay system. RESULTS A total of 94 pat...

Cultivar characterization for fruit trees certification requires fast, efficient and reliable techniques. Microsatellite markers (SSR) were used in the molecular characterization of 29 Prunus spp. rootstocks. The DNA from the rootstocks was analyzed using five pre-selected SSR primers (UDP96-005, UDP96-008, UDP96013, UDP96-18 and UDP98-414) and revealed 81 alleles, which allowed each genotype t...
