The objective of the study was to compare the water test and the hypoosmotic test (HOS) in the assessment of the human sperm membrane. A total of 686 semen samples from human male donors were subjected to water and HOS tests after routine semen evaluation. The mean percentage of swollen spermatozoa was 71.8 +/- 9.6% in the HOS test and 67.8 +/- 9.4% for the(More)
A retrospective study was undertaken on 178 cases (6.9% out of 2569 autopsies) of fatal pulmonary thromboembolism, 86 males and 92 females, aged 28-87 years (mean age = 71 +/- 13), in whom pulmonary emboli were found at autopsies, performed from 1971 to 1988. Fatal pulmonary thromboemboli means that no other cause of death was found at autopsy, and emboli(More)
A retrospective study was undertaken on 178 cases of fatal pulmonary thromboembolism, 86 males and 92 females, in whom major pulmonary emboli were found at autopsies, performed from 1971 to 1988. The 178 cases represent 6.9% from 2569 autopsies. In 43 cases (24.2%) the fatal pulmonary thromboembolism developed after surgery. The clinical diagnosis was(More)
A comparative study of 71 patients with unilateral primary breast cancer was performed to verify a possible correlation between the mammographic findings of the cancer and the content of hormonal receptor. The Nielsen & Poulsen, and Wolfe classification were employed. Hormonal receptor content was determined using the Taylor method. The estrogen content was(More)
A study on circadian and circannual rhythmicity in the episodes of fatal pulmonary thromboembolism has been conducted in 152 cases. The data demonstrate that the incidence in the episodes of pulmonary thromboembolism, evaluated as hour and day of onset in the clinical symptoms, presents a temporal, both circadian, and circannual distribution. The greater(More)
In order to assess the prognostic value of 15 different prognostic variables for multiple myeloma and to select the variables with the best prognostic significance, the multivariate analysis according to Cox's proportional hazard regression model was employed for a group of 80 patients followed from first diagnosis to their demise. The significant(More)
