Activity of single neurons in the nucleus accumbens (NAcc) of rats was recorded extracellularly on the 2nd and 15th days of intravenous cocaine self-administration. Each of the two electrophysiological recording sessions consisted of three successive phases: a pre-drug baseline recording period, a cocaine self-administration session, and a post-drug recording period. Firing of individual neuron...

Gothic Art and Architecture, religious and secular buildings, sculpture, stained glass, and illuminated manuscripts and other decorative arts produced in Europe during the latter part of the Middle Ages (5th century to 15th century). Gothic art began to be produced in France about 1140, spreading to the rest of Europe during the following century. The Gothic Age ended with the advent of the Ren...

Introduction: There is considerable evidence that glutamate-mediated excitatory neurotransmission plays an important role in mediating the behavioral actions of acutely administered ethanol. The aim of the present study was to investigate the effect of acute ethanol exposure on NR1 subunit of NMDA (n-methyl-d-aspartate) receptor distribution in the cerebral cortex of chick embryo on the 10th...

In this study we investigated the five-year-results of our smoking cessation outpatient clinic retrospectively. Out of 839 subjects admitted to our clinic during this time period 634 of them completed the one-year follow up period. 318 (50.2%) of these subjects were male and 316 (49.8%) of them were female. Subjects were divided into two groups. While one group received nicotine patch therapy, ...

PURPOSE To assess the advantages of iterative reconstruction for quantitative computed tomography (CT) analysis of pulmonary emphysema. MATERIALS AND METHODS Twenty-two patients with pulmonary emphysema underwent chest CT imaging using identical scanners with three different tube currents: 240, 120, and 60 mA. Scan data were converted to CT images using Adaptive Iterative Dose Reduction using...

In order to investigate the expression patterns of the transforming growth factor (TGF)beta isoforms in the internal ear, an immunohistochemical study of rat embryos was performed. Rat embryos were taken on the 13th, 15th, 17th, and 19th day after conception and their internal ears were immunohistochemically stained against TGF beta1, beta2, and beta3. As a result, the 13-day-old embryo showed ...

INTRODUCTION Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. OBJECTIVE The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency...

Herbicides adversely affect both the target plant and its environment. In this study, Helianthus annuus L. cv. “Oliva CL” was treated post-emergence with 0.3 to 3.1 mM quizalofop-p-ethyl. The peroxidase activity (POD), ascorbate peroxidase activity (APX), lipid peroxidation, pigment system and total phenolic content were then determined on the 1st, 5th, 10th and 15th days following treatment. T...

By Antonio Bonati, Paola Zanelli, Sergio Ferrari, Anna Plebani, Bruno Starcich, Mario Savi, and Tauro M. Neri T-cell ,receptor (TCR) @chain proteins appear early ( 15th week of gestation) during human thymic ontogenesis. These p-chain proteins, which appear before terminal deoxynucleotidyl transferase (TdT), could be an expression of a fully rearranged (V-D-J), incompletely rearranged (D-J), or...
