Both large, acute doses of erythropoietin (EPO) and short-term hypoxia increase platelet counts in mice, but long-term hypoxia causes thrombocytopenia. Therefore, we tested the hypothesis that EPO injected in large, chronic doses (a total of 80 U of EPO over a 7-day period) might cause thrombocytopenia. EPO caused increased red blood cell (RBC) production, ie, increased hematocrits, RBC counts,...

BACKGROUND AND OBJECTIVES Specially designed surgical instruments have been developed for single-incision laparoscopic surgery, but high instrument costs may impede the implementation of these procedures. The aim of this study was to compare the cost of operative implements used for elective cholecystectomy performed as conventional laparoscopic 4-port cholecystectomy or as single-incision lapa...

A short discussion of some conventional diagnostic techniques, followed by a discussion of the Raman effect and the laser Doppler anemometer, is given. The apparatus used at PINY and the techniques developed utilizing the Raman effect are described. Some experimental results concerning concentrations of mixtures and temperature measurements in flames are presented and discussed. ** This researc...

The purpose of this study is to demonstrate that the percentage of obese individuals initially presenting to total joint arthroplasty clinics in a public, tertiary hospital is greater than the proportion of obese individuals in the general population. In a retrospective, comparative study of patients seen in total joint replacement clinics at a public, tertiary hospital with an ICD-9 diagnosis ...

The hemostatic effect of platelets has been well-known since it was first reported by Duke in 1910.1 The possible role of red blood cells (RBC) in hemostasis was also suggested in that article. Since then, RBC transfusions have been used to stop uremic bleeding.2 In our previous experience, adequate RBC transfusion had good hemostatic effect in patients with anemia and thrombocytopenia.3 Thus, ...

OBJECTIVE To determine exercise efficacy in improving dynamic balance in community-dwelling elderly with a fall history. METHODS Thirty-five participants were randomly assigned to a treatment (TG; n = 19, 77 ± 7 yr) or control group (CG; n = 16, 75 ± 8 yr). The TG received an individualized home exercise program, and the CG received phone calls twice per week for 12 weeks. Participants' dynam...
