Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However,those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection(EFTR) is an evolving technique,which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

Over the last 10 years,numerous psychophysical studies have indicated that binocular mechanisms are structurally intact but functionally suppressed in amblyopia(1-8).Many of these studies have used a contrast balancing approach,whereby the contribution of each eye to binocular vision is equated or“balanced”by presenting higher contrast stimulus elements to the amblyopic eye than the fellow eye(6).Using this approach,the strength of suppression can be quantified by measuring the magnitude of interocular contrast difference required for normal binocular *** suppression strength has been correlated with other clinical measures,stronger suppression has been associated with worse stereoacuity and worse amblyopic eye visual acuity indicting a link between the monocular and binocular deficits in amblyopia(5,7).

Physical activity can enhance cognitive function and increase resistance against deleterious effects of stress on mental health. Enhanced cognitive function and stress resistance produced by exercise are conserved among vertebrates, suggesting that ubiquitous mechanisms may underlie beneficial ef- fects of exercise. In the current review, we summarize the beneficial effects of exercise on cognitive function and stress resistance and discuss central and peripheral signaling factors that may be critical for conferring the effects of physical activity to brain circuits involved in cognitive function and stress. Additionally, it is suggested that norepinephrine and serotonin, highly conserved monoamines that are sensitive to exercise and able to modulate behavior in multiple species, could represent a conver- gence between peripheral and central exercise signals that mediate the beneficial effects of exercise. Finally, we offer the novel hypothesis that thermoregulation during exercise could contribute to the emotional effects of exercise by activating a subset of temperature-sensitive serotonergic neurons in the dorsal raphe nucleus that convey anxiolytic and stress-protective signals to forebrain regions. Throughout the review, we discuss limitations to current approaches and offer strategies for future re- search in exercise neuroscience.
