2 +/- 14.1 vs. 53.4 +/- 10.9% mBq/cell after 30 min (P<0.05)]. Sixty percent of tracer accumulated in the cytosol, and, although total cellular retention increased during hypoxia, there was no enrichment in any particular cellular compartment.Conclusion This apparatus allows the conduction of radiotracer uptake studies in cells under complete atmospheric control, as evidenced by our first demonstration of the hypoxia-dependent uptake of Cu-64-ATSM in ventricular myocytes. It is ideally suited for screening, validating and characterizing

“We determined the temporal and spatial localization of the phytoalexin avenanthramide A, and its biosynthetic enzyme, hydroxycinnamoyl-CoA: hydroxyanthranilate N-hydroxy-cinnamoyltransferase (AsHHT) in oat leaves infected with the crown rust fungus. Accumulation of avenanthramide A and AsHHT was first observed predominantly in hypersensitive response (HR) cells at 36 h post inoculation (hpi), and later in adjacent cells at 48 hpi. At 120 hpi, avenanthramide A was

detected in a wider area of infected tissues, but AsHHT-positive signals were only observed in the HR and adjacent cells, suggesting that avenanthramide A was synthesized around the HR cells, and then transported to other parts of the infected tissues in a center-to-periphery manner.

“Aim: Tuberculosis (TB) continues to be an important health problem in Serbia, as a country with numerous socioeconomic problems. Health care www.selleckchem.com/products/Cyt387.html workers, especially medical CRT0066101 nmr and dental students could be key persons to engage in prevention of TB.\n\nThe aim of our study was to compare the knowledge level and awareness of TB among medical and dental students.\n\nMethods: Cross-sectional study was conducted at the School of Medicine and the School of Dentistry, University of Belgrade, Serbia. A sample of 350 students was selected by stratified sampling. Data about knowledge

and awareness of TB was collected through the anonymous (self-administered) questionnaire.\n\nResults: 300 questionnaires were returned; response rate was 85.7%. Medical students gave significantly higher correct responses about modes of transmission of TB (p<0.001). Significantly higher proportion of medical students (p=0.003) knew that age above 65 years is risk period of life for getting TB, but only 6.5% of them noted that the age of puberty is the risk period too. High proportion of both groups agreed that alcoholism and AIDS are the conditions, which can increase risk for getting TB. Medical students have better knowledge about therapy of TB, but there were no differences concerning questions about diagnosis.\n\nConclusion: In spite of valid basic awareness of TB, there were some gaps in the knowledge, more frequently among dental then medical students. This study suggests that students need more training and more practice.
