Chronical haloperidol and clozapine treatment in rats: Differential RNA display analysis, behavioral studies and serum level determination

1998

1. Adult, female rats were treated orally for 23 days with 1.6 mg/kg haloperidol or 36 mg/kg clozapine per day, to study chronic effects of the two neuroleptics. 2. At five time points during the neuroleptic treatment, animal behavior was recorded in an open field and locomotive activity was analysed. At the end of the experiment, rats were decapitated, blood samples were collected and serum concentrations of haloperidol and clozapine were determined by a radioreceptor or HPLC assay, respectively. RNA was isolated from each brain, without cerebellum, and subjected to differential RNA display. 3. Mean serum concentrations were 8 ng/ml for haloperidol and 21 ng/ml for clozapine. Analysis of o…

New approaches in the treatment of Adamantiades-Behçet's disease.

2005

Purpose of review To update clinicians on the recent advances in the treatment of Adamantiades-Behcet's disease. Recent findings Interferon-α-2a and infliximab have proved able to induce prompt remission in the vast majority of Adamantiades-Behcet's patients with DMARD-resistant uveoretinitis. Efficacy of interferon-α-2a has also been reported for mucocutaneous lesions, arthritis, and (more anecdotally) for neuro-Behcet, while results from small case series suggest that infliximab is beneficial for mucocutaneous lesions and (more anecdotally) for arthritis and gastro-intestinal manifestations. Two cases of neuro-Behcet treated with infliximab showed a complete resolution. Finally, in a rand…

Transcatheter Vs. Surgical Closure of Atrial Septal Defects in Adults

2018

Abstract Percutaneous transcatheter device closure of secundum atrial septal defects (ASD) has now largely replaced surgical closure in most centres. The aim of this study was to compare results of transcatheter and surgical ASD closure in adults in Latvia during the years 2002–2014 and to analyse long-term outcomes of transcatheter closure. We analysed data from 334 patients with secundum ASD who underwent ASD closure in Pauls Stradiņš Clinical University Hospital. Patients were included into device or surgical closure groups. In the device group, three follow-ups were made 1, 6, and 12 months after the procedure. No follow-up data were available for surgical arm patients beyond their hosp…

Vacuum-Assisted Abdominal Closure in Surgical Emergency: A Single Institution Experience Treating a Cohort with a Prevalence of Faecal Peritonitis

2021

Abstract Vacuum-assisted abdominal closure (VAAC) has evolved as a promising method for treatment of emergent surgical patients. The aim of the study was an assessment of the complication rate and outcomes following routine application of VAAC in a cohort of patients suffering predominantly with peritonitis of the lower gastrointestinal tract (GIT) origin. The prospectively collected data was analysed retrospectively, including demographic data, aetiological factors, comorbid conditions and severity of the disease. The indications for VAAC included complicated intra-abdominal infection, purulent peritonitis with sepsis and/or risk of increased intra-abdominal pressure. In total, 130 patient…

Canakinumab in systemic juvenile idiopathic arthritis: real-world data from a retrospective Italian cohort

2021

Abstract Objective The objective of this study was to use real-world data to evaluate the effectiveness and safety of canakinumab in Italian patients with systemic JIA (sJIA). Methods A retrospective multicentre study of children with sJIA was performed. Clinical features, laboratory parameters and adverse events were collected at baseline, and 6 and 12 months after starting canakinumab. The primary outcome measure of effectiveness was clinically inactive disease (CID) off glucocorticoids (GCs) treatment at 6 months. Results A total of 80 children from 15 Italian centres were analysed. Of the 12 patients who started canakinumab in CID while receiving anakinra, all maintained CID. Of the 68 …

Control of Acetylcholine Release and of Intestinal Motility by Subtypes of Muscarine Receptors

1988

Two types of neuronal muscarine receptors have been investigated in the myenteric plexus preparation of the guinea-pig small intestine: 1. Presynaptic receptors activation of which inhibits the depolarization-evoked release of acetylcholine. Pirenzepine and dicyclomine have low affinities to the release-inhibitory receptors (pA2 values 6.9 and 7.6) which suggests that the presynaptic receptors (similar to the smooth muscle receptors) belong to the M2 subtype. The inhibition of the electrically-evoked acetylcholine release by muscarine (0.01 - 1 μmol/1) was not affected by forskolin (1μmol/l). This indicates that cyclic AMP is not crucially involved in the muscarinic inhibition of acetylchol…

Migraine and cluster headache – the common link

2018

Abstract Although clinically distinguishable, migraine and cluster headache share prominent features such as unilateral pain, common pharmacological triggers such glyceryl trinitrate, histamine, calcitonin gene-related peptide (CGRP) and response to triptans and neuromodulation. Recent data also suggest efficacy of anti CGRP monoclonal antibodies in both migraine and cluster headache. While exact mechanisms behind both disorders remain to be fully understood, the trigeminovascular system represents one possible common pathophysiological pathway and network of both disorders. Here, we review past and current literature shedding light on similarities and differences in phenotype, heritability…

Optimal carbohydrate antigen 125 cutpoint for identifying low-risk patients after admission for acute heart failure

2022

Introduction and objectives: Carbohydrate antigen 125 (CA125) has been shown to be useful for risk stratification in patients admitted with acute heart failure (AHF). We sought to determine a CA125 cutpoint for identifying patients at low risk of 1-month death or the composite of death/HF readmission following admission for AHF.Methods: The derivation cohort included 3231 consecutive patients with AHF. CA125 cutoff values with 90% negative predictive value (NPV) and sensitivity up to 85% were identified. The adequacy of these cutpoints and the risk of 1-month death/HF readmission was then tested using the Royston-Parmar method. The best cutpoint was selected and externally validated in a co…

Proton conductance of human transient receptor potential-vanilloid type-1 expressed in oocytes of Xenopus laevis and in Chinese hamster ovary cells.

2004

Transient receptor potential-vanilloid type-1 (TRPV1) is a ligand-gated cation channel with preference for divalent cations, especially Ca(2+) (sequence of conductances: Ca(2+)Mg(2+)Na(+) approximately/= K(+) approximately/= Cs(+)). In the present study, the two-electrode voltage-clamp technique was used on oocytes of Xenopus laevis expressing TRPV1 to evaluate whether human TRPV1 also conducts protons. In medium devoid of K(+), Na(+), Mg(2+), and Ca(2+), capsaicin 1 microM induced a significant inward current (62% of the current in physiological medium). The effects of capsaicin were abolished in the presence of capsazepine 3 microM. The capsaicin-induced currents in medium devoid of Na(+)…
