Different prognostic value of exercise electrocardiogram in men and women.

In 1,455 subjects (947 men and 508 women) who underwent a bicycle ergometer stress test for evaluation of atypical chest pain, the incidence of coronary events (definite myocardial infarction or sudden death) was assessed by the life table method. The follow-up period ranged from 3 to 7 years (mean 5.2 years).

Variability of essential amino acid content in seeds of 22 Phaseolus species.

The reserve protein composition of 22 Phaseolus species has been studied. The non-sulphur-containing amino acids were present at values higher than those suggested for animal (and human) nutrition, but the sulphur-containing amino acids, with some exceptions, were under the minimum accepted requirement. However, taking into account the variability in the percentages of methionine and cystine, as well as the cystine/methionine ratio, it is concluded that the genus Phaseolus has a theoretical possibility for synthesizing a reserve protein with a balanced sulphur-containing amino acid content.
