Brain computer interface (BCI) is an assistive technology, which decodes neurophysiological signals generated by the human brain and translates them into control to external devices, e.g., wheelchairs. One problem challenging noninvasive BCI technologies limited dimensions from decoding movements of, mainly, large body parts, upper lower limbs. It has been reported that complicated dexterous functions, i.e., finger movements, can be decoded in electrocorticography (ECoG) signals, while it...

Prader–Willi syndrome (PWS) is a neurodevelopmental genetic disorder characterized by multiple system involvement with hypotonia, poor suck feeding difficulties, growth and other hormone deficiencies, intellectual disability, behavioral problems childhood onset of hyperphagia resulting in obesity, if not externally controlled. Transcranial direct current stimulation (tDCS) has been increasingly shown to modulate cognitive processes children adults, including food-intake behaviors patients...

BACKGROUND Esophageal chromoendoscopy with iodine solution is important for detecting early esophageal cancer. The effect of routine treatment lesions lightly stained Lugol’s limited, and the addition natural substances to a regular diet becoming increasingly common. Vinegar has antitumor effects as reported in previous studies. AIM To evaluate whether vinegar supplementation could improve prognosis patients lesions.

Although most large submucosal tumors in the esophagus such as leiomyomas are benign, obstructive symptoms may develop owing to their size [1]. Endoscopic resection of remains difficult [2], and exophytic mid-esophagus worst. The main problem is presence important adjacent organs bronchus, aorta, spine. We report a novel concept for facilitating endoscopic resection: 3D-printed model guidance tumor (3DM-GTR). model, based on enhanced computed tomography, could clearly display anatomy details...
