HLA CW3 and HLA CW4 have a protective effect on acquisition of chronic myeloid leukemia on Mexican patients.

Introduction: Chronic myeloid leukemia (CML) is characterized by a chromosomal translocation t(9; 22) resulting in the chimeric ber-abl oncogene that encode for the p210 protein which has an increased tyrosine kinase activity. The fusion part of this protein contains a novel aminoacid sequence. If peptides derived from this leukemia-specific part of p210 are expressed in the context of HLA molecules on malignant cells this may elicit immunologically specific responses.

Changes on hemostatic parameters induced by 17beta-estradiol, ethinylestradiol, and the 17beta-aminoestrogen pentolame in the male Wistar rat.

Oral contraceptives containing estrogens increases the incidence of thromboembolic events. In contrast, administration of 17beta-aminoestrogens prolonged blood clotting time (BCT) in rodents. We studied the effect of estradiol (E(2)), ethinylestradiol (EE) and pentolame on some screening hemostatic tests.

Increased incidence of anxiety and depression during bone marrow transplantation.

Background: Since the first organ transplantation in the 1950s, there have been reports that patients who underwent organ transplantation had a poor prognosis if they were depressed and/or anxious prior to transplantation. Our objective in this study was to determine the prevalence of anxiety and depression in the different stages of bone marrow transplantation (BMT).

Methods: Mood disorders (MD), anxiety disorders (AD), and adjustment disorders (ADD) were measured five times with DSM IV.
