INTRODUCTION Metastases are detected in 20% of patients with solid tumours at diagnosis and a further 30% after diagnosis. Radiation therapy (RT) has proven effective in bone (BM) and brain (BrM) metastases. The objective of this study was to analyze the variability of RT utilization rates in clinical practice and the accessibility to medical technology in our region. PATIENTS AND METHODS We ...

An important class of sequential-sampling models for response time (RT) assumes that evidence for competing response alternatives accrues in parallel and that a response is made when the evidence total for a particular response exceeds a criterion. One member of this class of models is the Poisson counter model, in which evidence accrues in unit increments and the waiting time between increment...

Single neurons in the primary visual cortex (V1) show variability in spike activity in response to an identical visual stimulus. In the current study, we examined the behavioral significance of the variability in spike activity of V1 neurons for visually guided saccades. We recorded single-cell activity from V1 of monkeys trained to detect and make saccades toward visual targets of varying cont...

We report a new technique for the continuous and real-time measurement of microparticle-induced cellular responses using a real-time cell-electronic sensing (RT-CES) technology. The method involves the use of microelectrode-embedded microwells seeded with one of two lung cancer carcinoma cell lines (A549 and SK-MES-1), allowing for continuous measurements of impedance. The change in impedance t...

We developed an immunomagnetic separation (IMS) technique combined with real-time TaqMan reverse transcriptase PCR (RT-PCR), which allowed detection of norovirus at a level as low as 3 to 7 RT-PCR units from artificially contaminated strawberries. The inoculum recovery rate ranged from 14 to 30%. The data demonstrate that IMS combined with real-time RT-PCR will be useful as a rapid and sensitiv...

avian infectious bronchitis (ib), caused by a gammacoronavirus, is an oie-listed (list b) disease and characterized by respiratory and renal involvements, causing high mortality, and economic loss in both layers and broilers. in comparison with other diagnostic methods, real-time polymerase chain reaction (rt-pcr) and conventional rt-pcr are potent, more sensitive and faster techniques for infe...

background: parasitic nematodes cause animal and human diseases of major socio-economic importance worldwide. the suppression of parasite development at particular developmental stages could provide an alternative approach for nema-tode control. in this study, ascaris suum was used as a model system in the study of the differentially expressed genes in the infective l3 stage. methods: the gene ...
