When thyroxine is submitted to paper electrophoresis in barbitone buffer at pH 8.6 in the presence of either an ultrafiltrate of trypsin-digested serum or of phenylalanine or other amino acids it migrates Nike Air Max 97
towards the anode to a position close to that of human serum thyroxine-binding protein (TBP), whereas at pH 7.6 it hardly moves from the origin. Under the same conditions triiodothyronine remains near the origin at both pH 8.6 and pH 7.6. A method of testing for the presence of TBP in biological materials is suggested; based on a study of the electrophoretic mobility of thyroxine and triiodothyronine in barbitone buffer at pH 8.6 and pH 7.6.
Although menstruation is still considered a natural event by women in India, Nike Air Max 1 Essential perceptions about menstruation are changing. We report on our study of 1150 urban and 850 rural women. The urban women included high school and college students, professional women,
and housewives. A 10-point questionnaire was pretested in a clinic setting and then administered to the study group. The responses show that 80% of high school and college students and professional women wish to have infrequent menses or no menses at all. In contrast, 70% of rural women prefer to have monthly menses. The authors wish to initiate a debate on this issue among health care providers and women's groups.
