Similar efficacy of low and standard doses of transdermal estradiol in controlling bone turnover in postmenopausal women
2006
To investigate the effects of a low transdermal estradiol dose on bone metabolism and to compare it with both the standard dose and absence of treatment.In this study performed in a third-level academic center, 66 healthy postmenopausal women underwent hormone therapy (HT) with patches containing estradiol at standard (0.050 mg/day, HT50, 33 women) or low dosage (0.025 mg/day, HT25, 33 women) and 70 women were without treatment (NT). The values (mean of three samples) of several bone biochemical parameters were compared between groups after adjusting for confounding factors. Bone mineral density (BMD) was assessed (by dual-energy X-ray absorptiometry) in the spine and hip in all cases, and …
Raloxifene promotes prostacyclin release in human endothelial cells through a mechanism that involves cyclooxygenase-1 and -2
2005
Objective To examine the effects of raloxifene on prostacyclin production by human umbilical vein endothelial cells (HUVEC) and to shed light on the molecular details of that action. Design Cell culture for 4, 8, 16, 24, and 48 hours. Setting University research laboratory. Patient(s) Source of HUVEC. Intervention(s) Measurement of prostacyclin production and of protein levels and mRNA expression of cyclooxygenase (COX)-1 and -2. Main Outcome Measure(s) Prostacyclin production was measured by enzyme immunoassay, the mRNA expression of COX-1 was measured by quantitative real time-polymerase chain reaction, and the protein levels of COX-1 and -2 were measured by immunoblotting. Result(s) Ralo…
Characteristics of histamine tachyphylaxis in rat uterine smooth muscle.
2002
Objective and design: To study both the desensitisation induced by short-term exposure to histamine and the mechanism responsible in the isolated rat uterus.¶Material: Precontracted isolated uterus (37 mM KCl) from oestrogenised Wistar rats were used.¶Treatment: Repetitive responses to histamine (10–6, 10–5, 10–4, 10–3 M), dimaprit and clonidine (10–4 M) were tested at 15, 30, 45 and 105 min., with their modifications by (5 mg/ kg, 24 h before sacrifice) reserpine, 10–7 M propranolol, 10–8 M atropine, and 10–6 M indomethacin. Dose-response curves for adrenaline were carried out as standard protocol.¶Methods: In vitro techniques (de Jalon's solution, 31°C, carbogen, isotonic registration, re…
Personalised Medicine in National Cancer Plans: How Can Innovation Be Translated Into Policy?
2014
ABSTRACT Stratified, precision or personalised medicine (PM) is emerging as one of the most important areas of clinical innovation in cancer care. Yet, implementing policies to translate these innovations to practice entails deep changes, including in how patient information is treated, how funding is allocated, how diagnostic tests are validated and carried out, how care is organised, how clinical trials are conducted and how new drugs are approved. National Cancer Control Programmes (NCCPs), for their part, have emerged as the primary instrument to coordinate the range of cancer control policies within individual countries, and virtually all European countries have adopted one. This means…
Inhibition of intracellular Ca2+ release by a Rho-kinase inhibitor for the treatment of ischemic damage in primary cultured rat hippocampal neurons.
2008
The effects of hydroxy fasudil, a specific Rho-kinase inhibitor, on behavior and brain neuronal activity in animal studies have been described previously. However, whether a Rho-kinase inhibitor can directly protect neurons against ischemic damage and the molecular mechanisms underlying these effects are poorly understood. The present work was designed to investigate the effect of hydroxy fasudil against oxygen-glucose deprivation (OGD) induced acute neuronal injury and the underlying mechanisms in vitro. Pretreatment with hydroxy fasudil at 5 and 10 microM could concentration-dependently improve cell viability and decrease Lactate dehydrogenase (LDH) level in extracellular solution of neur…
Cardiovascular disease in primary sjögren’s syndrome
2018
Background A close relationship between rheumatic diseases and cardiovascular disease (CVD) has been reported, accounting for the higher mortality and morbidity observed in these patients. In the last years, it has been clearly reported that patients affected by primary Sjogren's syndrome (pSS) experienced an increased risk of CVD. Objective This review aimed at investigating CVD, traditional cardiovascular (CV) risk factors and possible targeted therapeutic strategies in pSS patients. Method Available literature concerning CV risk factors in pSS patients has been selected and discussed. Conclusion Disease-related characteristics and traditional CV risk factors contribute to observed athero…
Cloning of two melanocortin (MC) receptors in spiny dogfish
2004
We report the cloning and characterization of two melanocortin receptors (MCRs) from the spiny dogfish (Squalus acanthias) (Sac). Phylogenetic analysis shows that these shark receptors are orthologues of the MC3R and MC5R subtypes, sharing 65% and 70% overall amino acid identity with the human counterparts, respectively. The SacMC3R was expressed and pharmacologically characterized in HEK293 cells. The radioligand binding results show that this receptor has high affinity for adrenocorticotropic hormone (ACTH)-derived peptides while it has comparable affinity for alpha- and beta-melanocyte stimulating hormone (MSH), and slightly lower affinity for gamma-MSH when compared with the human ortho…
Intimate partner violence against women and the Nordic paradox
2016
Nordic countries are the most gender equal countries in the world, but at the same time they have disproportionally high prevalence rates of intimate partner violence (IPV) against women. High prevalence of IPV against women, and high levels of gender equality would appear contradictory, but these apparently opposite statements appear to be true in Nordic countries, producing what could be called the 'Nordic paradox'. Despite this paradox being one of the most puzzling issues in the field, this is a research question rarely asked, and one that remains unanswered. This paper explores a number of theoretical and methodological issues that may help to understand this paradox. Efforts to unders…
A review of settings-based health promotion with applications to sports clubs.
2013
Sports clubs have a long and tradit ional history in many countries, ye t they remain underdeveloped and underutilized settings for health promotion. Leisure ti me settings, in general, have been in minor role among settings-based health promotion initiatives. Curre nt health concerns in western countries, such as sedentary lifestyles and obesity, have aroused a need to expand he alth promotion to include also settings with greater potential to reach and engage children and adoles cents in more vigorous activity. To develop these alternative, most often non-institutiona l, settings to the level of the established ones, it is important to review what has been done, what ha s been accepted, a…
Can bureaucrats order public health? The case of Norway
2013
Introduction: The implementation of a new structural reform, the Coordination Reform, prioritizing a new public health agenda, was initiated to develop a more decentralized, integrated health care system in Norway in 2012. The same year, new health legislation was implemented and due to the new Public Health Act the responsibility for implementing a new public health agenda was decentralized to the local level. Historically, due to lack of funding – these issues have got low priority among local authorities. The new public health legislation reflects a shift in policy focus from treatment to illness prevention – where planning and partnership among primary end specialist health care, as wel…
