Estrogen receptor agonists and immune system in ovariectomized mice.
2006
Several data implicate the immune system in bone lost after estrogen deficiency, however, some of the effects on the immune system of estrogen deficiency or of estrogen receptor (ER) modulation are not well established. In this study, the effect of ER agonists on the immune system in ovariectomized mice is analyzed. Mice were ovariectomized and were administered 17β-estradiol (E2), raloxifene (RAL) or genistein (GEN). The effect of a 4-week treatment on bone turnover and on several parameters that reflect the status of the immune system was studied. Results show that ovariectomy provoked both uterine atrophy and thymic hypertrophy. Although RAL corrected thymic hypertrophy, only E2 correct…
Comparative effects of estradiol, raloxifene, and genistein on the uterus of ovariectomized mice.
2005
To explore the uterine effects of administration of compounds that exert their bone-sparing functions through estrogen receptors, we administered 17beta-E2, raloxifene, or genistein to ovariectomized mice and analyzed the uterus weight and histology 4 weeks after beginning the treatments. Results indicated that raloxifene and genistein have partial agonistic properties on the uterus in estrogen-depleted mice, and that genistein induced apoptosis and several atypias in the glandular epithelium of endometrium, as demonstrated in hematoxylin-eosin-stained histological sections.
Infections associated with medical devices: pathogenesis, management and prophylaxis.
2005
The insertion or implantation of foreign bodies has become an indispensable part in almost all fields of medicine. However, medical devices are associated with a definitive risk of bacterial and fungal infections. Foreign body-related infections (FBRIs), particularly catheter-related infections, significantly contribute to the increasing problem of nosocomial infections. While a variety of micro-organisms may be involved as pathogens, staphylococci account for the majority of FBRIs. Their ability to adhere to materials and to promote formation of a biofilm is the most important feature of their pathogenicity. This biofilm on the surface of colonised foreign bodies is regarded as the biologi…
Ibandronic acid subsequent to raloxifene: Effect on bone metabolism and on cardiovascular risk factors
2015
s / Maturitas 81 (2015) 144–190 161 Materials andmethods: This randomized double-blind clinical trialwas carried out inAhvaz (Iran) fromAugust toDecember 2010. Forty postmenopausal women with symptoms of vaginal atrophy were randomly allocated to two groups to take vaginal suppositories of either 5mg hyaluronic acid sodium salt (n=20) or 1mg vitamin E (n=20) for 8 weeks. The symptoms of vaginal atrophy were evaluated by a self-assessed 4-point scale and the composite score was determined as none, mild, moderate, and severe in four periods. Results: The results showed that the symptoms were relieved significantly in both groups (P<0.001). The relief of symptomswas significantly superior in t…
Three-dimensional hysterosonography for the study of endometrial tumors: comparison with conventional transvaginal sonography, hysterosalpingography,…
1997
We studied endometrial thickness and homogeneity in 36 patients with postmenopausal bleeding using three-dimensional ultrasound following distention of the uterine cavity with a sterile saline solution (3D-SHSG). Results with 3D-SHSG were compared with findings using transvaginal sonography, transvaginal sonohysterography, transvaginal color Doppler, and hysteroscopy. Sixteen patients (including three on tamoxifen) were undergoing hormone therapy at the time when they were studied. Visualization of the uterine cavity and of endometrial thickness was better with 3D-SHSG than with any of the other ultrasound techniques. The results with 3D-SHSG corresponded to the findings observed with hyste…
Multicenter experience with the antegrade fenestration and reentry technique for chronic total occlusion recanalization
2020
Objectives We aimed to evaluate the efficacy and safety of antegrade fenestration and reentry (AFR) for chronic total occlusion (CTO) recanalization in a multicenter registry. Background Adoption of antegrade dissection/reentry (ADR) for CTO recanalization has been limited, and novel ADR techniques are needed. Methods AFR involves the balloon-induced creation of multiple fenestrations between the false and true lumen. A targeted true lumen reentry is subsequently achieved with a low tip-load polymer-jacketed guidewire. Following the initial description and dissemination of AFR, patients undergoing AFR-based CTO recanalization at nine centers were included in the present registry. Study endp…
Novel Combination of Sorafenib and Celecoxib Provides Synergistic Anti-Proliferative and Pro-Apoptotic Effects in Human Liver Cancer Cells
2013
Molecular targeted therapy has shown promise as a treatment for advanced hepatocellular carcinoma (HCC). Sorafenib, a multikinase inhibitor, recently received FDA approval for the treatment of advanced HCC. However, although sorafenib is well tolerated, concern for its safety has been expressed. Celecoxib (Celebrex®) is a selective cyclooxygenase-2 (COX-2) inhibitor which exhibits antitumor effects in human HCC cells. The present study examined the interaction between celecoxib and sorafenib in two human liver tumor cell lines HepG2 and Huh7. Our data showed that each inhibitor alone reduced cell growth and the combination of celecoxib with sorafenib synergistically inhibited cell growth an…
Tubular carcinoma of the breast: Outcome and loco-regional recurrence in 307 patients
2005
Abstract Purpose The aim of this study is to describe the University of Florence experience in evaluating clinical, pathologic and treatment factors as they are related to the outcome and loco-regional recurrence in patients with tubular breast carcinoma. Material and methods Three hundred and seven patients (median age 56.4 years, range 26–91 years) with histological verified tubular carcinoma of the breast were consecutively treated at University of Florence from 1976 to 2001. All patients were followed for a median of 8.4 years (range 3 months to 20 years). Thirty-seven women underwent mastectomy and 270 underwent breast conserving surgery. Positive axillary nodes were found in 15% of pa…
Spontaneous labour at term is associated with fetal monocyte activation.
1999
SUMMARYThe aetiology of both term and preterm labour remains incompletely understood. Maternal infectious diseases as well as intra-uterine infections were shown to be a well established cause of uncontrollable preterm delivery, indicating that inflammatory reactions, regulated by maternal immunecompetent cells, are implicated in labour-promoting mechanisms. To investigate the possibility that the activation of the fetal immune system may be involved in labour induction, we examined cytokine production patterns of different cord blood cell populations obtained from neonates after spontaneous onset of normal term labour and vaginal delivery (n = 25), vaginal delivery but induced term labour …
Fastlegers informasjonsbehov ved medisinsk avstandsoppfølging : En kvalitativ studie
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Bakgrunn:For å møte den fremtidige økningen i forekomsten av ikke-smittsomme kroniske sykdommerhar Norge prøvd utmedisinsk avstandsoppfølging siden2016. Resultatene så langt viser en økt trygghet, samt følelse av oppfølging og kontroll over egen helse hos pasientene. Det understrekes at det å involvere fastleger i tjenestene har vært utfordrende(Helsedirektoratet, 2018a). Videreutprøvingble startet opp i 2018 og er planlagt å fortsette til og med2021. Hensikt:Formålet med denne masteroppgaven er å bidra med kunnskap om hvordan IKT best mulig kan understøtte fastlegenes tiltenkte rolle som koordinator i medisinsk a…
