Using a Temperature Gradient against the Time in Polyacrylamide Gel Electrophoresis May Eliminate the Need for Stacking Gels
Background and Objectives: Making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. Considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity. Ultimately, a downward tempera...
متن کاملWhy Minimum Wage Hikes May Not Reduce Employment
may accept findings that minimum wage increases do not adversely affect employment, but economists question them. Critics have charged that the studies use poor data or incorrect methodologies. Some economists also argue that no convincing theoretical model predicts that minimum wage increases do not reduce employment.

متن کاملHaemoccult does not reduce the need for colonoscopy in surveillance after curative resection for colorectal cancer.
Patients who had undergone curative resection for colorectal cancer were studied to compare the efficacy of faecal occult blood detection (Haemoccult test) with colonoscopy in the detection of metachronous tumours. Fifty nine patients were studied and both Haemoccult testing and colonoscopy were successfully completed in 54 patients. In 37 patients, both tests were negative. One patient with a ...
متن کاملLow-Dose Sevoflurane May Reduce Blood Loss and Need for Blood Products After Cardiac Surgery
Patients undergoing cardiac surgery often experience abnormal bleeding, due primarily to cardiopulmonary bypass (CPB)-induced activation of platelets. Sevoflurane may inhibit platelet activation, raising the possibility that administering it during CPB may reduce blood loss.Patients between 18 and 65 years old who were scheduled for cardiac surgery under CPB at our hospital were prospectively e...
متن کاملAdenoidectomy May Not Be Effective to Reduce the Number of Hospital Visits for Sinusitis
BACKGROUND The objective of this study was to compare post-operative (post-op) visits for sinusitis between adenoidectomy and non-adenoidectomy participants (control). METHODS Using the national cohort study from the Korean Health Insurance Review and Assessment Service, we used 1:4 matching to select 2,593 adenoidectomy participants and 10,372 control participants. Post-op visits for sinusit...
