The Inhibitory Effects of Prednisone, 16-Methylen-Prednisolone, and Acth on Con-A Induced Lymphokines (Interferon-Y) as Measured by the Chemiluminesc…
1988
When lymphocytes are stimulated with mitogens or antigens they are enhanced via a cascade of lymphokines to produce interferon-y (IFN-y). IFN-y augments the H2O2 secretion of human monocytes which indirectly can be measured by chemiluminescence. We tested prednisone, 16-methylen-prednisolone and ACTH for their effect to inhibit the Con-A induced stimulation of the chemiluminescence-activity. All three hormones inhibited significantly the stimulation: prednisone up to 52.5% (concentration = 150 micrograms/ml, p = 0.000005), 16-methylen-prednisolone up to 22.5% (concentration = 2.5 micrograms/ml, p = 0.006) and ACTH up to 33% (concentration = 10 micrograms/ml, p = 0.0036).
Constitutive androstane receptor activation stimulates faecal bile acid excretion and reverse cholesterol transport in mice.
2010
The constitutive androstane receptor (CAR) is a nuclear receptor expressed in the liver and involved in xenobiotic metabolism. The aim of this study was to assess whether pharmacological CAR activation could affect neutral sterol and bile acid elimination under conditions of cholesterol overload.Wild type, Car-/-, ApoE-/-, and low-density lipoprotein receptor (Ldlr)-/- mice fed a western-type diet were treated with the CAR agonist TCPOBOP.CAR activation was associated with a decrease in faecal cholesterol output related to the repression of the Abcg5/g8 cholesterol transporters. In contrast, TCPOBOP treatment induced a marked increase (up to three fold, p0.01) in the elimination of faecal b…

Antihistamine-resistant Angioedema in Women with Negative Family History: Estrogens and F12 Gene Mutations
2013
Abstract Background In women with sporadic recurrent angioedema with an unknown cause who are unresponsive to antihistamines and have normal C1 inhibitor activity and a negative family history of angioedema, it is unclear whether they have idiopathic angioedema or hereditary angioedema with normal C1 inhibitor, and what impact exogenous estrogens have on their angioedema. Methods A cohort of 147 women was analyzed for F12 exon 9 mutations and for the influence of oral contraceptives, hormonal replacement therapy, and pregnancy on their angioedema. Results A total of 142 women had idiopathic angioedema unresponsive to antihistamines. Five women had an F12 mutation and thereby hereditary angi…
Anti-inflammatory effects of zinc in PMA-treated human gingival fibroblast cells
2015
Objectives: Abnormal cellular immune response has been considered to be responsible for oral lesions in recurrent aphthous stomatitis. Zinc has been known to be an essential nutrient metal that is necessary for a broad range of biological activities including antioxidant, immune mediator, and anti-inflammatory drugs in oral mucosal disease. The objective of this study was to investigate the effects of zinc in a phorbol-12-myristate-13-acetate (PMA)-treated inflammatory model on human gingival fibroblast cells (hGFs). Study Design: Cells were pre-treated with zinc chloride, followed by PMA in hGFs. The effects were assessed on cell viability, cyclooxygenease-1,2(COX-1/2) protein expression, …
Impact of Proportionality of Secondary Mitral Regurgitation on Outcome After Transcatheter Mitral Valve Repair
2020
The purpose of this paper was to evaluate the impact of proportionality of secondary mitral regurgitation (SMR) in a large real-world registry of transcatheter edge-to-edge mitral valve repair (TMVr) BACKGROUND: Differences in the outcomes of recent randomized trials of TMVr for SMR may be explained by the proportionality of SMR severity to left ventricular (LV) volume.The ratio of pre-procedural effective regurgitant orifice area (EROA) to LV end-diastolic volume (LVEDV) was retrospectively assessed in patients undergoing TMVr for severe SMR between 2008 and 2019 from the EuroSMR registry. A recently proposed SMR proportionality scheme was adapted to stratify patients according to EROA/LVE…
Cigarette smoke-induced pulmonary endothelial dysfunction is partially suppressed by sildenafil.
2009
Abstract Cigarette smoke mediated oxidative stress and endothelial dysfunction are important processes in the pathogenesis of several lung disorders. In this study we evaluated the effect of PDE5 inhibition on pulmonary artery endothelial dysfunction induced by cigarette smoke in vitro . Human pulmonary artery endothelial cells (HPAEC) were incubated in the absence or presence of PDE5 inhibitor sildenafil (10 nM–1 μM), PKG agonist 8-Br-cGMP (1 mM), or the antioxidants dyphenyleneiodonium (DPI 1 μM) and N -acetylcysteine (NAC 1 mM) for 30 min. Then, cigarette smoke extract (CSE) was added for 24 h. CSE (2.5–10%)-induced ROS generation was suppressed by DPI, and partially reversed by sildenaf…
Diagnosis of Endometrial Carcinoma: Predictive Value of Transvaginal Color Doppler
1995
The objective of this study was to determine whether transvaginal ultrasound plus color Doppler flow improve the ability to diagnose endometrial carcinoma and allow better discrimination between benign and malignant endometrial lesions. One hundred thirty women with abnormal uterine bleeding were evaluated with transvaginal color Doppler before fractional dilatation and curettage (D&C). The endometrial line thickness and endometrial characteristics were evaluated by endosonography. The resistive and pulsatile indices of the uterine arteries and of the endometrium were evaluated with transvaginal color Doppler. Following D&C and tissue diagnosis, women were divided into two groups, 62 with a…
Leg extension power deficit and mobility limitation in women recovering from hip fracture.
2008
OBJECTIVE: After hip fracture, muscle strength and power remain persistently poor, especially in the fractured leg. This study explores whether asymmetrical leg extension power (LEP) deficit affects mobility in women after proximal femoral fracture (PFF). DESIGN: In this observational study, LEP of both legs, 10- and 50-foot walking speed, and stair-climbing speed were measured in 43 women, aged 73-96, at 1 and 13 wks after surgical repair of PFF. Asymmetrical LEP deficit was calculated as (fractured/(sum both legs)) x 100%. RESULTS: Between weeks 1 and 13 after PFF surgery, LEP increased in the fractured and nonfractured legs by 100% and 30%, respectively. Asymmetrical deficit was reduced …
