The ventral tegmental area (VTA) as a major source of dopamine neurons projecting to cortical and limbic regions has a crucial role in reward as well as stress processes. Dopamine is a predominant neurotransmitter in the reward system, which plays an important role in both drug priming-induced and cue-induced reinstatement of cocaine and heroin seeking. It has been shown that this neurotransmitter has a role in stress-induced relapse to drug seeking. Therefore, the present study aims to evaluate the effects of intra-VTA administration of SCH-23390, as a dopamine D1-like receptor antagonist, and sulpiride, as a dopamine D2-like receptor antagonist, on drug priming-induced and food deprivation (FD)-induced reinstatement...

Titanium is a biocompatible material that is frequently used for making implantable medical devices. Nanoengineering of the surface is the common method for increasing material biocompatibility, and while the nanostructured materials are well-known to represent attractive substrata for eukaryotic cells, very little information has been documented about the interaction between mammalian cells and bactericidal nanostructured surfaces. In this study, we investigated the effect of bactericidal titanium nanostructures on PC12 cell attachment and differentiation—a cell line which has become a widely used in vitro model to study neuronal differentiation...

Acute liver failure (ALF) is a lethal disease with limited life-saving therapy. Because lack of whole organ donors for liver transplantation, a substitute treatment strategy is needed for these patients. Preclinical and clinical findings have proved that treatment with mesenchymal stem cells (MSCs) is beneficial for recovery from ALF. In this approach, however, the appropriate sources of these cells are unclear. In the present study, we investigated and compared the therapeutic potentials of bone marrow-mesenchymal stem cells (BM-MSC) with those of adipose tissue (AT-MSC) in carbon tetrachloride (CCL4)-induced acute liver failure in mice...

A major diagnostic challenge for cardiologists is to distinguish cardiac syndrome X (CSX) from obstructive coronary artery disease in women with typical angina and a positive exercise tolerance test (ETT). We performed this study to develop a scoring system that more accurately predicts CSX in this patient population. Data on 976 women with typical angina and a positive ETT who underwent coronary angiography at our center were randomly divided into derivation and validation datasets. We developed a backward stepwise logistic regression model that predicted the presence of CSX, and a scoring system was derived from it...
