Long non-coding RNA signatures in non-small cell lung cancer and their clinicopathological significance.

Lung cancer is the most common type of cancer in our country and worldwide, and it is a leading cause of cancer-related deaths. According to the latest global cancer statistics, lung cancer was identified as the second most common type of cancer, and the leading cause of cancer-related deaths. Long non-coding RNAs (lncRNAs) are a highly heterogeneous class of RNA molecules sharing many characteristics with mRNAs, except for the protein-coding potential.

Protective effects of wheat germ oil against erectile and endothelial dysfunction in streptozotocin-induced diabetic rats.

Our aim was to investigate the protective effect of wheat germ oil (WGO) at different doses on diabetes mellitus (DM)-induced erectile and endothelial dysfunction. Twenty-four male Wistar rats weighing 250-300 g were divided into four groups as; control group treated with saline, DM group, DM group treated with 3 ml/kg WGO (DM + 3WGO group), DM group treated with 6 ml/kg WGO. Type 1 DM was induced by intraperitoneal injection of 60 mg/kg streptozotocin (STZ).

Measuring Alexithymia via Trait Approach-I: A Alexithymia Scale Item Selection and Formation of Factor Structure.

Introduction: It is not clear in the literature whether available instruments are sufficient to measure alexithymia because of its theoretical structure. Moreover, it has been reported that several measuring instruments are needed to measure this construct, and all the instruments have different error sources. The old and the new forms of Toronto Alexithymia Scale are the only instruments available in Turkish.

Health profiles of methyl bromide applicators in greenhouses in Turkey.

Introduction: Methyl bromide is a toxic substance that has hazardous effects on human health with acute and chronic exposure. Our previous study showed that methyl bromide applicators frequently use large amounts of methyl bromide haphazardly in greenhouses in the prefectures of Narlidere and Balcova in the Aegean city of Izmir. This study aims to evaluate the health conditions of these workers.

The role of adenosine triphosphate-regulated potassium channels in propofol-induced beneficial effect on contractile function of hypercholesterolemic isolated rabbit hearts.

Objective: To investigate the role of adenosine triphosphate-regulated potassium (KATP) channels in the propofol-induced changes in the contractile function of hypercholesterolemic rabbit hearts.

Methods: This study was carried out in the Department of Pharmacology Laboratory, Faculty of Medicine, Dokuz Eylul University, Izmir, Turkey during the period January to December 2003. Twenty-two isolated rabbit hearts were grouped into 4.

[The effects of water-pipe, cigarette and passive smoking on mucociliary clearance].

We aimed to determine the effects of water-pipe smoking on lung mucociliary clearance system using radioaerosol ventilation scintigraphy and compare with cigarette and passive smoking and determine the level of exposure to tobacco smoke by measuring urinary cotinine in each group. Volunteer water-pipe only and cigarette only smokers from various cafés in Izmir city and passive smokers as control group were included in the study after exclusion and inclusion criteria. The ages, type of smoking, duration and daily amount of tobacco smoked and the medical histories of the volunteers were noted down.

Influence of carvedilol on serum digoxin levels in heart failure: is there any gender difference?

Objective: The activity of the human cytochrome P450 and P-glycoprotein (P-gp) changes according to gender. The present study evaluated the effect of gender on the influence of carvedilol on serum digoxin levels in patients with heart failure.

Methods: Twenty-four patients (12 female and 12 male) with New York Heart Association class II-III heart failure were included in the study.

Effects of lactational cyclosporine A use on rat pups.

We aimed to evaluate the structural and functional changes in the thymus and kidneys of rat pups whose mothers were given cyclosporine A (CsA) during lactational period. Six adult nursing Wistar rats and their 30 pups were studied. Rat pups were divided into four groups as follows: 21-day treated group and 21-day placebo group, each including 10 breastfeeding pups sacrificed on the 21st day, whose mothers were given CsA or placebo, respectively (infancy groups) and, 60-day treated group and 60-day placebo group, each including five breastfeeding pups sacrificed on the 60th day, whose mothers were given CsA or placebo, respectively (puberty groups).

The effects of gender and menopause on serum lidocaine levels in smokers.

It has been established that human cytochrome P450 (CYP) enzymatic activity is affected by gender, or by hormonal factors such as the menopause in women. Gender differences have a more pronounced effect on cytochrome (CYP) 3A4 isoenzyme activity, whereas cytochrome (CYP) 1A2 isoenzyme activity is mainly induced by chronic smoking. Lidocaine is frequently used in the treatment of hemodynamic changes following laryngoscopy and tracheal intubation during general anesthesia, and is metabolized by CYP3A4 and CYP1A2 isoenzymes in the liver.

Turkish coffeehouse kahvehane is an important tobacco smoke exposure area in Turkey.

This study was undertaken to investigate the extent of environmental tobacco smoke (ETS) exposure in coffeehouses, as these are commonly frequented public places in Turkey. From 86 coffeehouses in the 3 districts, 59 coffeehouse workers and 35 hospital staff members (as a control group) were evaluated. Participants answered a questionnaire about demographics, working characteristics, smoking behavior, and ETS exposure during their daily life lives.

Do adenosine receptors play a role in amitriptyline-induced cardiovascular toxicity in rats?

Objective: The aim of the our study was to investigate the role of adenosine receptors on cardiovascular toxicity induced by amitriptyline, a tricyclic antidepressant agent. Therefore, the hypothesis of this study was that adenosine receptor antagonists would improve and/or prevent amitriptyline-induced hypotension and conduction abnormalities in an anesthetized rat model of amitriptyline intoxication.

Methods: Two separate experimental protocols were performed.

Effect of menthol on the pharmacokinetics and pharmacodynamics of felodipine in healthy subjects.

Objectives: The present study was undertaken to determine whether menthol affects the metabolism of and pharmacological responses to the calcium channel antagonist felodipine in people.

Methods: Eleven healthy subjects (ten female, one male) participated in a randomized, double-blind, two-way crossover study, comparing the kinetics and effects of a single oral dose of felodipine ER tablet (Plendil, 10 mg) with menthol (test) or placebo (reference) capsules. Ten subjects completed the study.

The interaction of the diltiazem with oral and intravenous cyclosporine in rats.

This study investigated the effect of diltiazem on the bioavailability of oral and intravenous cyclosporine (CsA) in rats. While control rats received normal saline, experimental groups received 60 or 90 mg/kg diltiazem orally for 3 days. Each group divided into 2 equal groups that received a single oral dose or i.

Influence of menthol on caffeine disposition and pharmacodynamics in healthy female volunteers.

Objectives: The present study was undertaken to determine whether a single oral dose of menthol affects the metabolism of caffeine, a cytochrome P(450) 1A2 (CYP1A2) substrate, and pharmacological responses to caffeine in people.

Methods: Eleven healthy female subjects participated in a randomized, double-blind, two-way crossover study, comparing the kinetics and effects of a single oral dose of caffeine (200 mg) in coffee taken together with a single oral dose of menthol (100 mg) or placebo capsules. Serum caffeine concentrations and cardiovascular and subjective parameters were measured throughout the study.

The effect of the nitric oxide synthesis inhibitor L-NAME on amitriptyline-induced hypotension in rats.

Objective: Hypotension induced by tricyclic antidepressants is multifactorial. Previous animal experiments suggest a contribution from nitric oxide production. Our study aimed to evaluate the role of nitric oxide in amitriptyline-induced hypotension using N-nitro-L-arginine methyl ester, a nitric oxide synthesis inhibitor, and 3-morpholino sydnonimine, a nitric oxide donor, in anesthetized rats.
