OBJECTIVE To assess the risk factors that influence mortality from perforated peptic ulcer. DESIGN Retrospective study. SETTING General hospital, Taiwan. SUBJECTS 179 patients who had their perforated peptic ulcers operated on and who had minimum follow-up of one year. MAIN OUTCOME MEASURES Mortality. RESULTS The overall mortality was 15%(More)
Treatment is always abandoned in those HCC with jaundice, because it is usually attributed to the underlying liver cirrhosis and extensive tumor. In this series, 7 cases (0.8%) of HCC with jaundice were caused by bile duct invasion and tumor thrombi (BTT). 57% of cases showed Charcot's triad. 57% of BTT were small HCC, significantly higher than the 1.7% of(More)
Previous research has failed to consider the importance of caregiving circumstances and their impact on social support and caregiver burden. Hence, this study aimed to investigate the association between perceived and received social support and caregiver burden. This cross-sectional study was carried out on 301 family caregivers. Data was collected using(More)
The effect of clomiphene, an ovulation-inducing agent, on cytosolic free Ca2+ levels ([Ca2+]i) in MG63 human osteosarcoma cells was explored by using fura-2 as a Ca2+ indicator. Clomiphene at concentrations between 5-75 microM increased [Ca2+]i in a concentration-dependent manner with an EC50 of 50 microM. The [Ca2+]i signal consisted of an initial rise and(More)
PCR and hybridization assays are widely used for the detection and identification of Escherichia coli serogroups and serotypes. We used these techniques for the detection of E. coli O157:H7, a dominant serogroup among E. coli strains that are considered major public health problems worldwide. We developed a quantitative PCR assay using SYBR Green I, based(More)
DNA separations were performed in poly(ethylene oxide) (PEO) solutions prepared in 100 mM Tris-boric acid (TB) buffers using a capillary filled with TB buffers with concentrations up to 2.5 M, pH 10.0. The electroosmotic flow (EOF) increased with increasing the concentration of TB buffers till 1.5 M as a result of decreasing PEO adsorption on the capillary(More)
Single-base resolution in the separation of DNA markers V and VI was achieved in the presence of electroosmotic flow (EOF), using poly(ethylene oxide) (PEO) solutions containing ethidium bromide (EtB) under isocratic conditions. Furthermore, a new approach called stepwise capillary electrophoresis (SCE) has been developed for DNA analysis, including(More)
A new and simple method was demonstrated for separating phi X-174/Hae III DNA restriction fragments and DNA markers V and VI, respectively, without filling capillaries with polymer solutions prior to analysis. Using this novel method, poly(ethylene oxide) (PEO) solutions containing ethidium bromide migrated into capillaries by electroosmotic flow (EOF)(More)
Proteins were separated in 0.6% poly(ethylene oxide) (PEO) solutions using a capillary filled with buffers prior to analysis and were detected by laser-induced native fluorescence using a pulsed Nd:YAG laser. PEO solutions entered the capillary by electroosmotic flow (EOF) during the separation. The composition and concentration of the buffer affected the(More)
