AVERSIVE EVENT ANTICIPATION AFFECTS CONNECTIVITY BETWEEN THE VENTRAL STRIATUM AND THE ORBITOFRONTAL CORTEX IN AN FMRI AVOIDANCE TASK.

Aversive event anticipation affects connectivity between the ventral striatum and the orbitofrontal cortex in an fMRI avoidance task.

Ability to anticipate aversive events is important for avoiding dangerous or unpleasant situations.The motivation to avoid an event is influenced by the incentive salience of an event-predicting cue.In an avoidance fMRI task we used tone intensities to manipulate salience in order to study the involvement of the orbitofrontal cortex in processing o

Intensity modulated radiation therapy (IMRT): differences in target volumes and improvement in clinically relevant doses to small bowel in rectal carcinoma

Abstract Background A strong dose-volume relationship exists between the amount of small bowel receiving low- to intermediate-doses of radiation and the rates of acute, severe gastrointestinal toxicity, principally diarrhea.There is considerable interest in the application of highly jerome brown jersey conformal treatment approaches, such as intens

NONENZYMATIC BROWNING KINETIC REACTION AND ASCORBIC ACID DEGREDATION OF HEAT-TREATED ORANGE JUICE DURING STORAGE

The kinetics of ascorbic acid (AA) degradation and nonenzymatic browning (NEB) of heat-treated single strength orange juice (OJ) over a temperature between 70-95 oC for 2-10 min.and stored under opaque condition at 4 and 20 oC for 2 months have been studied.Analysis of kinetic data by measuring liftmaster expansion board absorbance at 420 nm (A420)

Tollip or not Tollip: what are the evolving questions behind it?

Tollip plays an important role in the interleukin-1 receptor IL-1R and Toll pathways.As a modulator of the immune pathway, it indirectly controls the amount of antimicrobial peptides.This could indicate a vital step in maintaining animal immune systems and preventing infection.Evolutionary questions are crucial to understanding the conservation and
