OBJECTIVE The aim of this study was to analyze the effect of transdermal estradiol replacement therapy (HRT) on immune function in menopausal women. STUDY DESIGN A prospective comparative study was carried out in 30 women, aged 48-55 years, who were divided into two groups; 20 of them received transdermal estradiol 50 microg/day during 3 months and 10 who(More)
BACKGROUND AND AIMS We undertook this study to assess the relationship between circulating adipokines and insulin resistance during pregnancy and postpartum in women with gestational diabetes mellitus (GDM). METHODS This was a prospective study including 60 women with GDM and 60 subjects with normal gestation who were evaluated at gestational week 30, 6(More)
OBJECTIVE Recent evidence suggests that adiponectin may play a role in bone metabolism. Previous studies demonstrated that the adiponectin levels had a negative correlation with bone mineral density (BMD) in women. However, little is known about the relationship between adiponectin and BMD in men. The aim of this study was to determinate the relationship(More)
The objective of this study was to determine the effect of body fat distribution and hyperinsulinemia on the occurrence of ovulation. Fifty-six women (20-35 years old) either with overweight or obesity (body mass index >/=25) were studied. They were classified in two groups according to waist/hip ratio (WHR); one with predominance of adiposity in the upper(More)
OBJECTIVE This study aimed to examine possible genetic effects of some retinol binding protein-4 (RBP4) single nucleotide polymorphisms (SNPs) on the risk of gestational diabetes mellitus (GDM). In addition, the SNPs were examined for their possible association with insulin resistance at 6 weeks after delivery. METHODS This was a prospective study of 100(More)
AIM Fetal intrauterine growth retardation (IUGR) is one of the most common obstetric problems, with a frequency of 12% in Mexico. In the past, investigations have focused on extrinsic causes of IUGR. More recent studies have examined the intrinsic factors that cause fetal intrauterine growth. Maintenance of fetal growth has been attributed to insulin-like(More)
Ernest H. Starling introduced the term hormone 100 years ago in his Croonian Lectures to the Royal College of Physicians in June 1905. It was demonstrated for the first time that one part of the body could influence the function of another distant part. Starling for the first time suggested the word hormone. This review attempts to trace the development of(More)
Serum immunoreactive FSH was undetectable in a) pregnant women past 38 weeks of gestation, b) newborn infants, and c) anencephalic infants. The intravenous administration of 100 mug of synthetic LHRH elicited no FSH release in each instance. These results seem to indicate that the absence of FSH in serum in pregnant women in the last trimester, as well as(More)
