Initial-state nuclear effects in proton-nucleus collisions

Two important initial-state nuclear effects in hadron-nucleus collisions are considered. The ratios of inclusive differential cross sections for Drell-Yan dimuon production are calculated. The calculated results are compared to the E866 data. It is shown that consideration of multiple soft rescatterings of incident quarks in nuclei and initial-state quark energy loss effects allow to get a good agreement between the calculated results and the experimental data.Comment: 6 pages, 6 figure

Mechanisms of reabsorption of ions in the Henle’s loop and furosemide pharmacodynamics

The article explains mechanisms of reabsorption of ions in the thick segment of the ascending limb of Henle’s loop. The principle of action of one of the key representatives of "loop" diuretics, Furosemide, is examinedВ статье дается объяснение механизмов реабсорбции ионов в толстой части восходящего колена петли Генле. Рассматривается принцип действия одного из ключевых представителей «петлевых» диуретиков – фуросемида

Analysis of prostate gland biopsy findings in clinics of Yekaterinburg from 2000 to 2006

Introduction. New facilities in the diagnosis of prostate cancer and their wide introduction into the every-day practice bring about significant changes in the epidemiology of this clinical entity.The application of screening tests with biopsy has led to developing of heterogeneous diagnostic contingents. They are characterized by various methods of forming, by stage of disease revealed on the first level of medical aid, by demographic indices.Objective. To evaluate the structure of the diagnostic contingents formed in the patient care institutions of Sverdlovsk region we analyzed the findings of the prostate biopsies performed.Subjects and methods. The results of 3133 prostate biopsies carried out in five patient care institutions of Yekaterinburg for a period from 2000 to 2006 were analyzed taking into account the specificity of these institutions. All the biopsies were carried out transrectally, under the control of ultrasound.Results. Significant differences in grouping according to the stages of newly determined cases of the disease were obtained depending on the profile of the patient care institution.Conclusion. When evaluating the diagnosis of the prostate cancer it is necessary to take into consideration the heterogeneity of the diagnostic contingents depending on the profile of the patient care institution. The percentage of the positive biopsies findings and grouping according to the stages of newly determined cases, on the whole, may serve as epidemiologic indices
