Preoperative assessment of breast cancer: sonography versus MR imaging.
2002
The purposes of our study were to compare the diagnostic value of whole-breast sonography and MR imaging as adjunctive techniques to mammography and to determine whether MR imaging should be used routinely in the preoperative assessment of patients with suspected breast cancer.. One hundred four women (age range, 34-84 years; mean age, 60 years) with findings highly suggestive of malignancy in the breast were examined with mammography, sonography, and dynamic MR imaging before undergoing surgery. All visualized suspicious lesions were correlated histologically. The diagnostic relevance of sonographic and MR imaging findings was compared with the diagnostic value of the findings of clinical …
Serum basal hormone concentrations, nutrition and physical fitness during strength and/or endurance training in 39-64-year-old women.
2009
We examined effects of 21 weeks of strength and/or endurance training and nutrition on serum hormones and physical fitness in 39-64-year-old women. Subjects (n=79) were randomized into the endurance group (E), strength group (S), combined group (SE) and controls (C). Total body strength training and high-intensity bicycle training were used. Average energy and nutrient intake remained the same in all groups. Body fat (dual energy X-ray absorptiometry) decreased significantly in all training groups and body mass index in E, SE and C. Only SE increased total body lean mass (2.2%, p=0.001), between groups p=0.044. Maximal cycling power increased more in E (16%) and SE (17%) than in S (8%)(all …
LONG-ACTING AND SELECTIVE SUPPRESSION OF GROWTH HORMONE SECRETION BY SOMATOSTATIN ANALOGUE SMS 201-995 IN ACROMEGALY
1984
In 6 of 7 acromegalic patients a single subcutaneous injection of 50 micrograms of a new octapeptide somatostatin analogue (SMS 201-995) reduced serum growth hormone (GH) from 30 +/- 12 ng/ml to 1.4 +/- 0.4 (mean +/- SEM). Serum GH remained below basal concentration for 9 h. In the remaining patient who had very high basal preprandial serum GH, SMS 201-995 produced a reduction in serum GH of only 20%. Plasma glucose concentrations were increased to the upper limits of the normal range when a high-carbohydrate meal was consumed 2 h after injection. In non-diabetic patients plasma glucose did not exceed 129 mg/dl. The 40% decrease in plasma glucagon, which lasted for 7 h after SMS 201-995 inj…
Growth factor concentrations and their placental mRNA expression are modulated in gestational diabetes mellitus: possible interactions with macrosomia
2009
Abstract Background Gestational diabetes mellitus (GDM) is a form of diabetes that occurs during pregnancy. GDM is a well known risk factor for foetal overgrowth, termed macrosomia which is influenced by maternal hypergycemia and endocrine status through placental circulation. The study was undertaken to investigate the implication of growth factors and their receptors in GDM and macrosomia, and to discuss the role of the materno-foeto-placental axis in the in-utero regulation of foetal growth. Methods 30 women with GDM and their 30 macrosomic babies (4.75 ± 0.15 kg), and 30 healthy age-matched pregnant women and their 30 newborns (3.50 ± 0.10 kg) were recruited in the present study. Serum …
Neuromuscular and hormonal responses in elite athletes to two successive strength training sessions in one day
1988
Acute neuromuscular and endocrine adaptations to weight-lifting were investigated during two successive high intensity training sessions in the same day. Both the morning (I) (from 9.00 to 11.00 hours) and the afternoon (II) (from 15.00 hours to 17.00 hours) training sessions resulted in decreases in maximal isometric strength (p less than 0.01 and less than 0.05), shifts (worsening) in the force-time curve in the absolute scale (p less than 0.05 and ns.) and in decreases in the maximal integrated EMG (p less than 0.01 and less than 0.05) of the selected leg extensor muscles. Increases in serum total (p less than 0.05) and free testosterone (p less than 0.01) and in cortisol (p less than 0.…
Fibrinolytic parameters in normotensive pregnancy with intrauterine fetal growth retardation and in severe preeclampsia
1991
In pregnancy a decrease in fibrinolytic activity, which is due to an increase in plasminogen activator inhibitor activity and plasminogen activator inhibitor type 1 and type 2, has been described. Because the placenta is a source of both type 1 and type 2 plasminogen activator inhibitor, we have studied them and other fibrinolytic parameters in a group of normotensive pregnant women with intrauterine fetal growth retardation and in two groups of women with preeclampsia, with or without intrauterine growth retardation. A significant increase in plasminogen activator inhibitor type 1 antigen and plasminogen activator inhibitor activity was observed in preeclampsia, with or without intrauterin…
Association of Inflammation Markers with Impaired Insulin Sensitivity and Coagulative Activation in Obese Healthy Women
2003
Abstract Insulin resistance is associated with a low chronic inflammatory state. In this study we investigated the relationship between impaired insulin sensitivity and selected markers of inflammation and thrombin generation in obese healthy women. We examined 32 healthy obese women (body mass index ≥ 28), with normal insulin sensitivity (NIS, n = 14) or impaired insulin sensitivity (n = 18), and 10 nonobese women (body mass index < 25). Impaired insulin sensitivity patients had significantly higher levels of C-reactive protein (CRP), TGF-β1, plasminogen activator inhibitor-1 (PAI-1), activated factor VII (VIIa), and prothrombin fragment 1 + 2 (F1 + 2) compared with either control s…
Fumigation of Brazil nuts with allyl isothiocyanate to inhibit the growth of Aspergillus parasiticus and aflatoxin production
2017
Abstract BACKGROUND Brazil produces approximately 40 000 tons of Brazil nuts annually, which is commonly contaminated with fungi and mycotoxins. Gaseous allyl isothiocyanate (AITC) was used to inhibit the growth of Aspergillus parasiticus and its production of aflatoxins (AFs) in Brazil nuts. RESULTS Nuts were inoculated with 104 spores g−1 of A. parasiticus and placed in airtight glass jars with controlled relative humidity (RH = 95 or 85%). Samples were treated with 0, 0.5, 1.0 or 2.5 µL L−1 of gaseous AITC and analyzed after 30 days to determine the fungal population and AFs content. Samples were also submitted to sensory evaluation. AITC at 2.5 µL L−1 could completely inhibit the fungal…
Rapid antibiotic susceptibility testing on blood cultures using MALDI-TOF MS
2018
International audience; Antibiotic resistance is a major public health problem requiring the early optimization of antibiotic prescriptions. Matrix-Assisted Laser Desorption Ionization-Time Of Flight Mass Spectrometry (MALDI-TOF MS) has been shown to accurately identify bacteria from positive blood culture. Here, we developed a rapid detection of Escherichia coli resistance to amoxicillin (AMX) and cefotaxime (CTX) from positive blood culture based on MALDI-TOF MS. Potential sparing of broad-spectrum antibiotics was also evaluated. We tested 103 E. coli-positive blood cultures. Blood cultures were subculture 1-hour in antibiotic-free rich liquid media before further incubation with and with…
Moving European research on work and ageing forward: Overview and agenda:
2010
This paper summarizes the state of affairs of European research on ageing and work. After a close inspection of the age construct, an overview is presented of research in four areas: the relationship between age and HR-policies, early retirement, age and performance/employability, age and health/well-being. The overview results in a research agenda on work and ageing and in recommendations for practice. © 2009 Psychology Press. ispartof: European Journal of Work and Organizational Psychology vol:19 issue:1 pages:76-101 status: published
