What Do Younger and Well-Educated Adults Think about Self-Medication? Results of a Survey during a Public Science Event at Leipzig University.

Background: Consecutive visitors to a public science event at Leipzig University were asked about their opinions/attitudes regarding their personal use of self-medication.

Methods: A written questionnaire survey addressed (i) participants' characteristics, (ii) frequency of self-medication use in the last 12 months, (iii) symptoms/complaints most frequently considered applicable, (iv) preconditions, (v) limitations, (vi) risks, (vii) fears, (viii) medication information sources, (ix) influencing factors, and (x) reasons for decision making.

Results: (i) A total of 189 visitors (median age: 29.

Development and Verification of a Body Weight-Directed Disease Trial Model for Glucose Homeostasis.

Weight loss has been associated with improvement in insulin sensitivity. It is consequently a cornerstone in the management of type 2 diabetes mellitus (T2DM). However, the strictly quantitative relationship between weight loss, insulin sensitivity, and clinically relevant glucose homeostasis biomarkers as well as changes therein as T2DM progresses is not yet fully understood.

Riociguat for interstitial lung disease and pulmonary hypertension: a pilot trial.

We assessed the safety, tolerability and preliminary efficacy of riociguat, a soluble guanylate cyclase stimulator, in patients with pulmonary hypertension associated with interstitial lung disease (PH-ILD). In this open-label, uncontrolled pilot trial, patients received oral riociguat (1.0-2.

Naturally occurring regulatory T cells (CD4+, CD25high, FOXP3+) in the antrum and cardia are associated with higher H. pylori colonization and increased gene expression of TGF-beta1.

Background: Helicobacter pylori causes gastric inflammation. Despite the induction of H. pylori-specific B- and T cells, the immune response is not sufficient to clear the infection.

Almotriptan in migraine patients who respond poorly to oral sumatriptan: a double-blind, randomized trial.

Objective: To investigate the efficacy and tolerability of almotriptan 12.5 mg in migraine patients who respond poorly to sumatriptan 50 mg.

Background: Poor response to sumatriptan therapy for acute migraine attacks has been documented in the literature, but few controlled trials have investigated the efficacy of an alternative triptan in this subgroup of patients.

Cathepsins K, L, B, X and W are differentially expressed in normal and chronically inflamed gastric mucosa.

The expression of cathepsins K, L, B, X and W was studied by quantitative RT-PCR in normal and inflamed gastric mucosa (antrum, corpus, cardia). Cathepsins B, L, K and X were expressed ubiquitously. In contrast, cathepsin W was expressed at very low levels.

TFF3 expression at the esophagogastric junction is increased in gastro-esophageal reflux disease (GERD).

At the gastric cardia, the molecular mechanisms of inflammation and metaplasia are incompletely understood. Thus, the aim of this study was to determine the expression of TFF1, TFF2 and TFF3 at this site and correlate these data with Helicobacter pylori infection or gastro-esophageal reflux disease (GERD). In 27 patients without intestinal metaplasia at the cardia, endoscopic biopsies were obtained for histology and RT-PCR.

[New aspects in pain research at Bayer].

Considerable advances in the fields of molecular biology and pain research during the last decade has led to the identification of a wide range of pharmacological targets for new analgesics. Genes of interesting targets may be regulated either upwards or downwards under pathophysiological, i. e.

Transport characteristics of differently charged cephalosporin antibiotics in oocytes expressing the cloned intestinal peptide transporter PepT1 and in human intestinal Caco-2 cells.

To investigate whether multiple peptide transporters mediate absorption of beta-lactams carrying different charges at physiological pH, we used the human intestinal cell line Caco-2 and Xenopus laevis oocytes expressing the cloned rabbit intestinal peptide transporter PepT1. Characteristics of transport of the anionic cefixime and the zwitterionic cefadroxil were assessed by 1) flux studies using radiolabeled compounds, by 2) measuring changes in pHin in cells and oocytes as a consequence of substrate-mediated proton influx and 3) by applying the two-electrode voltage clamp technique to assess the electrophysiological phenomena associated with beta-lactam transport in oocytes expressing PepT1. Both beta-lactams were rapidly taken up into Caco-2 cells and oocytes expressing PepT1 by a pH-dependent and saturable transport pathway.

General pharmacology of the putative cognition enhancer linopirdine.

The putative cognition enhancer linopirdine (3,3-bis(4-pyrindinylmethyl)-1-phenylindolin-2-one, CAS 105431-72-9) is supposed to act by enhancing the release of neurotransmitters, especially acetylcholine. The present study assessed the effects of a single administration of this compound on the central nervous system in eight different rat and mouse models (CNS general pharmacology). In each test performed, linopirdine was administered subcutaneously in doses of 3, 10, and 30 mg/kg.

Biphasic effect of pyrazolone derivatives on drug-metabolizing enzyme in rat liver.

The pyrazolone derivatives aminophenazone, phenazone, and propyphenazone known as inducers are capable of inhibiting initially monooxygenase-dependent biotransformation steps. In the dose of 1.5 mmol X kg-1 they prolong the hexobarbital narcosis (max.
