Memantine and SKF82958 but not an enriched environment modulate naloxone-precipitated morphine abstinence syndrome without affecting hippocampal tPA mRNA levels in rats.

There is accumulating evidence supporting the involvement of tissue-plasminogen activator (tPA) in the mechanisms underlying the effects of morphine and an enriched environment. This study was designed to investigate possible interactive roles of the glutamatergic and the dopaminergic systems regarding hippocampal tPA in the neurobiology of morphine dependence. For this purpose, Wistar albino rats, housed in either a standard- (SE) or an enriched environment (EE) were implanted subcutaneously with morphine (150 mg base) or placebo pellets.

The Role of the Left Atrial Strain Parameters on Grading of Aortic Regurgitation.

Background: Grading the severity of aortic regurgitation (AR) is very important for clinical follow-up. In AR, left atrial (LA) mechanics can be affected in time and LA strain variations can be illuminating for the grading of AR. The purpose of this study is to determine whether the LA strain parameters are associated with the severity of AR or not.

Evaluation of aortic distensibility in patients with mitral valve prolapse using echocardiography and applanation tonometry.

Objective: Mitral valve prolapse (MVP) is a heart valve anomaly that affects a considerable segment of the population. Studies of patients with isolated MVP have shown that aortic distensibility decreased as the aortic diameter increased. The aim of this study was to compare evaluations of aortic distensibility in MVP patients using both applanation tonometry and the conventional echocardiographic examination.

Insulin-like growth factor-1 levels predict myocardial injury and infarction after elective percutaneous coronary intervention: an optical coherence tomography study.

Introduction: Periprocedural myocardial necrosis, which can range from a low level elevation of cardiac biomarkers to a large myocardial infarction (MI), is a common complication after percutaneous coronary intervention (PCI).

Aim: We hypothesized that insulin-like growth factor-1 (IGF-1) levels may play a protective role in myocardial injury after coronary stent placement and aimed to investigate the relationship between IGF-1 levels and plaque characteristics assessed by optical coherence tomography (OCT).

Material And Methods: Between May 2015 and December 2015 we prospectively enrolled 74 patients with stable angina pectoris in whom single de novo coronary artery stenosis was present.

Rationale, design, and methodology of the EPIC (Epidemiology of Polypharmacy and Potential Drug-Drug Interactions in Elderly Cardiac Outpatients) study.

Objective: The aim of this study is to assess the prevalence of polypharmacy, inappropriate drug use, and drug-drug interactions (DDIs) in elderly patients presenting at outpatient cardiology clinics in Turkey.

Methods: The EPIC (Epidemiology of Polypharmacy and Potential Drug-Drug Interactions in Elderly Cardiac Outpatients) study will be an observational, real-world, multicenter study conducted to evaluate DDIs and polypharmacy in elderly cardiac outpatients. All consecutive patients (aged ≥65 years) admitted to outpatient cardiology clinics between July 30, 2018 and July 30, 2019 who provide written, informed consent will be enrolled.
