Dexamethasone suppresses eNOS and CAT-1 and induces oxidative stress in mouse resistance arterioles

2004

Long-term treatment with glucocorticoids is associated with mild to moderate hypertension. We reported previously that downregulation of endothelial NO synthase (eNOS) expression and activity is likely to contribute to this increase in blood pressure. In the present study, we tested the effects of dexamethasone on the vasodilation of microvascular arterioles using implanted dorsal skin-fold chambers in anesthetized C57BL/6J mice. Experiments were performed on control mice or on mice treated with dexamethasone (0.1–3 mg/kg of body wt). Endothelium-dependent vasodilation in response to ACh (0.1–10 μM) was reduced by dexamethasone in a dose-dependent fashion. Comparable inhibition was seen in …

Effect of cocaine and related drugs on the uptake of noradrenaline by heart and spleen

1961

Noradrenaline uptake by heart and spleen after intravenous infusion of noradrenaline was measured in the pithed rat. Cocaine, given before the infusion, inhibited the noradrenaline uptake in relation (a) to the dose administered and (b) to the amount of noradrenaline infused. There was an association between increase in the pressor response to a test dose of noradrenaline and inhibition of the uptake by the heart. Drugs related chemically to cocaine, such as alpha-cocaine, amethocaine, and atropine, did not alter the noradrenaline uptake or potentiate the blood pressure response to noradrenaline. The noradrenaline uptake by the heart was unchanged after dibenamine, but blocked by the dichlo…

Hysteroscopic and ultrasonographic evaluation of ulipristal acetate treatment for symptomatic myomas in premenopausal women: a prospective study

2020

Objective: This study aimed to analyze the effects of a six-month therapy with ulipristal acetate (UPA) on myoma size and endometrial thickness in premenopausal women. Material and methods: Seventy-four women undergoing conservative therapy with UPA were enrolled for this study. All women underwent transvaginal ultrasound evaluation to assess the endometrial thickness, and the number and size of myomas at the beginning and after six months. Hysteroscopy and biopsy were performed after six months, if necessary. Results: After six months of treatment, sonographic examination showed a statistically significant (p <.05) reduction of the size of the largest myoma (56.3 ± 5.1 vs. 31.7 ± 10.1 m…

Lack of binding of gestodene to estrogen receptor in human breast cancer tissue

1990

Competition studies with progesterone and estradiol receptors of human myometrial tissue as well as of mammary cancer tissue showed that gestodene bound with high affinity to the progesterone receptor, as did other synthetic and natural progestogens. However, gestodene did not bind to the estradiol receptor. The relative binding affinities of all tested synthetic and natural ligands showed no organ-specific differences and no differences between neoplastically transformed and normal tissues.

Guidelines for Youth Sports Clubs to Develop, Implement, and Assess Health Promotion Within Its Activities

2014

The settings approach to health promotion is a world-known concept concerning settings like city, hospital, school, and workplace. The concept has also been used in some regionally specific settings, such as island, prison, or university. However, there are still many, often noninstitutional, settings that have a lot of potential but have not yet been recognized. One of the newcomers is the youth sports club, which has the potential to reach a lot of children and adolescents and is effective, via its casual educational nature based on voluntary participation. According to research, health is an important aim for most youth sports clubs, but it has not been converted into practical actions.…

P–409 Comparison of the incidence of ectopic pregnancies in fresh versus frozen embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Co…

2021

Abstract Study question Is the incidence of ectopic pregnancy (EP) increased in fresh compared with frozen embryo transfer (ET)? Summary answer The fresh ET is not associated with an increase of the incidence of EP in comparison with frozen ET. What is known already EP represents the first cause of mortality in the first trimester of pregnancy. Assisted reproductive technologies (ART) are associated with an increased EP risk. The reasons of this effect are inadequately explained and may be associated with variables patients-related as tubal diseases and ART-related as the number of embryos transferred, the depth of insertion of the catheter tip during ET and the supraphysiological estradiol…

Optical analysis to predict outcomes after implantation of a double intraocular lens magnification device.

2007

Purpose To analyze the effect of different optical parameters of the eye on the outcomes of implantation of a double intraocular lens (IOL) magnification device in patients with low vision. Setting Fundacion Oftalmologica del Mediterraneo, Valencia, Spain. Methods The eye's refraction and magnification before and after surgery were evaluated using a theoretical eye model based on paraxial optics approximation. Four parameters on which refraction and magnification are dependent were evaluated: anterior chamber depth (ACD), axial length (AL), mean keratometry (Km), and the distance between the 2 implanted IOLs. The 4 variables were analyzed separately in the first stage. Next, different combi…

Vascular leiomyoma in the oral cavity : report of two cases

2019

Vascular leiomyomas (VL) are benign lesions of perivascular origin. We report two new cases and discuss their clinical, histological and immunohistochemical characteristics, in order to facilitate the diagnosis and treatment of such lesions. The patients, both male, presented asymptomatic nodules located in the bottom of the labial sulcus and buccal mucosa. In the second case, color doppler ultrasonography was performed, which showed no change in blood flow. After excisional biopsies, a limited lesion was observed histologically, with multiple tortuous vessels of varying sizes and calibers, and among them, spindle cells bundles, positive for smooth muscle actin. Oral VLs have clinical featu…

Tetralogy of Fallot as a Model to Study Cardiac Progenitor Cell Migration and Differentiation During Heart Development

2009

Tetralogy of Fallot (ToF) has long been considered a congenital disorder that occurs due to environmental alterations during gestation. Recently, several mutated genes have been discovered that are thought to be responsible for the malformations observed in ToF. These genetic mutations, which are microdeletions, are sporadic and are frequently also present in trisomy 21 patients. The ToF malformations can be lethal, but for the last 50 years, surgical repairs that place an artificial patch to repair the four features of ToF have improved the survival of patients with ToF. However, 0.5% to 6% of patients who survive after surgical repair of ToF die of sudden cardiac death caused by ventricul…
