Effect of inhibition of the electrogenic Na+/K+ pump on the mechanical activity in the rat uterus.

1996

The effects of ouabain and K(+)-free solution were studied in estrogen-primed rat uterine strips under resting tone or repeatedly stimulated with KCl, acetylcholine or oxytocin applied for 20 minutes at 60 minute intervals. These effects were compared with those of the K+ channel opener cromakalim. In preparations under resting tone, ouabain (0.1 mM and 0.3 mM) induced rhythmic contractions which disappeared after 20-30 minutes whereas at a higher concentration (1 mM) it evoked a rapid, phasic response followed by a small tonic contraction. Exposure of the strip to a K(+)-free solution induced either rhythmic waves, which ceased after 8-10 minutes, or a single phasic contraction which was f…

Cromakalim inhibits electrically-evoked [3H]acetylcholine release from a tube-preparation of the rat isolated trachea by an epithelium-dependent mech…

1993

Rat isolated tracheae were labelled by incubation with [3H]choline to measure the tritium efflux elicited by electrical stimulation of the extrinsic parasympathetic nerves in vitro. Stimulated tritium efflux reflects the neuronal release of newly synthesized acetylcholine; the effects of potassium channel openers on the stimulated tritium efflux were investigated. In tracheae opened longitudinally neither cromakalim nor its 3S,4R-enantiomer, BRL 38227, reduced the stimulated tritium efflux, whereas in intact tube-preparations cromakalim (0.01-1 mumol/l) mediated a concentration-dependent inhibition. The inhibitory effect of 1 mumol/l cromakalim was prevented by 0.1 mumol/l glibenclamide. Li…

MORBILIDAD PSÍQUICA, EXISTENCIA DE DIAGNÓSTICO Y CONSUMO DE PSICOFÁRMACOS. DIFERENCIAS POR COMUNIDADES AUTÓNOMAS SEGÚN LA ENCUESTA NACIONAL DE SALUD …

2010

Background: Most of the studies on sychological distress in Spain have been conducted in small geographical areas or specific population groups. However, there are no studies that provide representative data for each Autonomous Community (AC). The objectives of this paper are to determine, both in Spain and in the AC, the prevalence of psychological distress, diagnosis, use of psychoactive medication, social support and self-perceived health, as well as to study the association between psychological distress and the rest of the variables. Methods: Cross-sectional study, using data from the 2006 National Health Survey, that was completed by 29,478 persons. Variables studied: sociodemographic…

Facilitatory and inhibitory muscarine receptors on the rat phrenic nerve: effects of pirenzepine and dicyclomine

1988

Neuronal transmitter stores of the rat phrenic nerve were labelled by an incubation with [3H]choline. Release of [3H]acetylcholine was elicited either by a short (100 pulses, 5 Hz) or by a long (1500 pulses, 5 or 25 Hz) period of electrical nerve stimulation. Pirenzepine and dicyclomine enhanced transmitter release evoked by the short stimulation period. Both antagonists reduced transmitter release evoked by the long stimulation period. Pirenzepine reduced transmitter release at low concentrations (1 nmol/l) whereas a higher concentration was necessary for the enhancing effect; the opposite pattern was found for dicyclomine. A low concentration of oxotremorine (10 nmol/l) enhanced and a hig…

Immunochemotherapy with Fludarabine (F), Cyclophosphamide (C), and Rituximab (R) (FCR) Versus Fludarabine and Cyclophosphamide (FC) Improves Response…

2008

Abstract Introduction: Previous phase II studies have suggested that a combination of FCR may increase the outcome of both untreated and relapsed CLL pts. In order to validate this concept the German CLL study group (GCLLSG) initiated a multicentre, multinational phase III trial, CLL8, to evaluate the efficacy and tolerability of FCR versus FC for the first-line treatment of pts with advanced CLL. Methods and Patients: 817 pts with good physical fitness as defined by a cumulative illness rating scale (CIRS) score (Extermann et al., JCO 1998) of up to 6 and a creatinine clearance (cr cl) □d 70 ml/min were enrolled between July 2003 and March 2006. Pts were randomly assigned to receive 6 cour…

Efficacy of Caplacizumab in Patients with aTTP in the HERCULES Study According to Initial Immunosuppression Regimen

2019

Background: Acquired thrombotic thrombocytopenic purpura (aTTP) is an acute, life-threatening thrombotic microangiopathy that requires urgent and specialized treatment. Prior to the introduction of caplacizumab, the treatment for aTTP was based on daily therapeutic plasma exchange (TPE; to replenish functional ADAMTS13 enzyme) plus immunosuppression (mainly corticosteroids and rituximab; to suppress anti-ADAMTS13 autoantibody production). TPE combined with immunosuppressive therapy improved outcomes in patients; however, episodes of aTTP are still associated with an acute mortality of up to 20% as these therapies do not have an immediate effect on the pathologic microvascular thrombosis. Th…

Safety of Topical Non-steroidal Anti-Inflammatory Drugs in Osteoarthritis: Outcomes of a Systematic Review and Meta-Analysis

2019

Objective We aimed to assess the safety of topical non-steroidal anti-inflammatory drugs (NSAIDs) in the management of osteoarthritis (OA) in a systematic review and meta-analysis of randomized, placebo-controlled trials. Methods A comprehensive literature search was undertaken in the MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus electronic databases. Randomized, double-blind, placebo-controlled, parallel-group trials that assessed adverse events (AEs) with topical NSAIDs in patients with OA were eligible for inclusion. Authors and/or study sponsors were contacted to obtain the full report of AEs. The primary outcomes were overall severe and serious AEs, as w…

Ombitasvir plus paritaprevir plus ritonavir with or without ribavirin in treatment-naive and treatment-experienced patients with genotype 4 chronic h…

2015

Summary Background Hepatitis C virus (HCV) genotype 4 accounts for about 13% of global HCV infections. Because interferon-containing treatments for genotype 4 infection have low efficacy and poor tolerability, an unmet need exists for effective all-oral regimens. We examined the efficacy and safety of an all-oral interferon-free regimen of ombitasvir, an NS5A inhibitor, and paritaprevir (ABT-450), an NS3/4A protease inhibitor dosed with ritonavir (ombitasvir plus paritaprevir plus ritonavir), given with or without ribavirin. Methods In this multicentre ongoing phase 2b, randomised, open-label combination trial (PEARL-I), patients were recruited from academic, public, and private hospitals a…

Does the Intrapelvic Compartment Syndrome Exist?

1998

Pelvic compartment syndrome is a rare condition. As in other musculoskeletal localizations, the intra-compartmental pressure raises above a critical level. In the pelvic compartment syndromes, the gluteal compartments are mainly concerned. We report on three patients with bilateral ureteral obstruction, due to compression by a massive retroperitoneal haematoma as a complication of an unstable pelvic ring or acetabular fracture. Anuria with renal organ failure, due to compression of the ureters in the small true pelvis represents an intrapelvic compartment syndrome. Anuria, due to ureteral compression, mostly developing 24 to 48 hours after injury, has to be differentiated from anuria due to…
