Clinical Relevance of Thyroid-Stimulating Immunoglobulins in Graves' Ophthalmopathy
2011
Purpose Thyroid-stimulating immunoglobulins (TSIs) likely mediate Graves' ophthalmopathy (GO). The clinical relevance of these functional autoantibodies was assessed in GO. Design Cross-sectional trial. Participants A total of 108 untreated patients with GO. Methods Thyroid-stimulating immunoglobulins, assessed with a novel bioassay, bind to the thyrotropin receptor (TSHR) and transmit signals for cyclic adenosine monophosphate (cAMP)-dependent activation of luciferase gene expression. The cAMP/cAMP response element-binding protein/cAMP-regulatory element complex induces luciferase that is quantified after cell lysis. The TSI levels were correlated with activity and severity of GO and compa…
Increased LH and FSH release from the anterior pituitary of ovariectomized rat, in vivo, by copper-, nickel-, and zinc-LHRH complexes.
1992
Abstract The effect of Cu 2+ , Ni 2+ , Zn 2+ and their complexes with LHRH on the release of luteinizing hormone (LH) and follicle stimulating hormone (FSH) was estimated in in vivo experiments with the use of the method proposed by Ramirez and McCann. Ovariectomized, estradiol, and progesterone pretreated rats were injected intraveneously either with LHRH alone, a metal ion alone, a mixture of metal and hormone, or a metal-LHRH complex. A metal alone or a mixture of it with LHRH did not affect gonadotropin release at all or no more than LHRH alone. However, the complex of Cu 2+ with LHRH brought about a high release of LH and even higher release of FSH. This indicates that copper complex i…
STIMULATING THE STUDENTS’ CREATIVITY IN THE FOREIGN LANGUAGE CLASS
2010
Throughout one’s life time each individual is required to find solutions to different problems by carrying out new operations, by combining the data and knowledge available, or by joining together disparate pieces of information. The students’ creative potential must be formed through teaching techniques that stimulate their resourcefulness: the essay, the scientific paper, the research project and the portfolio, which can be used as useful complementary evaluation methods as well.
Therapeutic dosages of oral or transdermal estradiol did not modify sCD40L levels in postmenopausal women.
2008
The CD40/CD40L system is considered a crucial modulator of the inflammatory process underlying the progression and complication of atheroma plaques. The soluble fraction of CD40L (sCD40L) is a reliable indicator of the CD40/CD40L system. Our purpose was to investigate whether a therapeutic dose of estradiol, by either the oral or the transdermal route, was associated with changes in circulating levels of sCD40L. Forty-seven women completed a 4-week course of treatment with either oral estradiol valerate (2 mg/day, 20 women) or transdermal estradiol (50 microg/day, 27 women). Serum levels of sCD40L were measured by conventional enzyme-linked immunosorbent assay. Oral, but not transdermal est…
Body mass reduction markedly improves muscle performance and body composition in obese females aged 61-75 years: comparison between the effects exert…
2004
OBJECTIVE: To investigate the effectiveness of a body mass reduction programme entailing diet caloric restriction and moderate physical activity with or without supplementary treatment with recombinant (r) GH or steroids to improve body composition and muscle performance in severely obese women aged 61-75 years. METHODS: Twenty women were randomly assigned to one of three groups: body mass reduction alone; body mass reduction plus rGH; body mass reduction plus nandrolone undecanoate. Body composition, isotonic muscle strength and anaerobic power output during jumping were determined before and after the 3-week period. RESULTS: Whatever the experimental group considered, body mass (P<0.01…
Does hysterectomy with ovarian conservation affect bone metabolism and density?
2002
We evaluated whether hysterectomy with ovarian conservation (HYX) has an effect on bone metabolism and density in 176 healthy Caucasian postmenopausal women aged 48-59 years. Bone properties of the hip, spine, radius, tibia, and calcaneus were measured using different bone assessment modalities. In addition, bone turnover was assessed using serum bone-specific alkaline phosphatase (BAP), osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) 5b as biomarkers. Our results showed that women having HYX had a significantly lower level of OC ( P = 0.017) and a marginally lower level of TRAP 5b ( P = 0.051) and higher bone mineral density (BMD) of the femoral neck ( P = 0.037) and lumba…
Physical Performance During the Menopausal Transition and the Role of Physical Activity
2020
Abstract Background To examine longitudinal changes in physical performance during the menopausal transition and the role of physical activity (PA) in these changes. Methods Based on follicle-stimulating hormone levels and bleeding diaries, women (47–55 years) were classified as early (n = 89) and late perimenopausal (n = 143) and followed prospectively until postmenopausal status, with mean duration of 17.5 and 13.8 months, respectively. Physical performance was measured by handgrip force, knee extension torque, vertical jumping height, maximal walking speed, and 6-minute walking distance. Physical activity was self-reported and categorized as inactive, low, medium, and high. Longitudinal …
