The parietal mechanisms of eye-hand coordination during reaching were studied by recording neural activity in area PEc while monkeys performed different tasks, aimed at assessing the influence of retinal, hand-, and eye-related signals on neural activity. The tasks used consisted of 1) reaching to foveated and 2) to extra-foveal targets, with constant eye position; and 3) saccadic eye movement ...

The cerebral cortex must have access to an eye position signal, as humans can report passive changes in eye position in total darkness, and visual responses in many cortical areas are modulated by eye position. The source of this signal is unknown. Here we demonstrate a representation of eye position in monkey primary somatosensory cortex, in the representation of the trigeminal nerve, near cel...

abstract objective: diabetic peripheral neuropathy is the main risk factor of diabetic foot ulcer and its early diagnosis is important to prevent limb amputation. we assessed the prevalence of peripheral neuropathy in diabetic patients. materials and methods: this cross-sectional study was performed on 352 randomly selected diabetic patients using a standardized questionnaire including age, gen...

background: because of the adverse effects of ionizing radiation on fetuses, prior to radiotherapy of pregnant patients, fetal dose should be estimated. fetal dose has been studied by several authors in different depths in phantoms with various abdomen thicknesses (at). in this study, the effect of maternal at and depth in fetal dosimetry was investigated, using peripheral dose (pd) distributio...

cytomegalovirus is the most important pathogen affecting transplant recipients and causing significant morbidity and morbidity. the prevalence of cmv  infections in transplant recipient varies from country to country.  the aim of this study was to determine the prognostic value of pcr assay for cmv  detection in patients before keratoplasty.  a total of 23 patient samples enrolled in this study...

malignant peripheral nerve sheath tumor (mpnst) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. the cell of origin is believed to be the schwann cell and possibly other nerve sheath cells. in this report, we describe a rare case of mpnst that arise from the socket of second left maxillary molar that has been already extracted in a young man. he was ref...

background: the standard method for repair of an injured peripheal nerve is epineural repair with separate sutures. herein we describe a method in which the nerve is sutured with continous sutures. in fact this method has not been utilized for nerve repair previously and our purpose was to compare it to the standard method. if it proved to be successful it would replace the standard method in c...

The hybrid polymer was synthesized by a radical polymerization of a B(12) derivative and a Ru complex having styrene moieties in each peripheral position, and the hybrid polymer showed photocatalytic activity for molecular transformation with visible light irradiation.

An unusual case of peripheral hypoglossal nerve palsy, caused by lateral position of the external carotid artery and an abnormally high carotid bifurcation is reported. Improvement followed ligation and cutting of the external carotid artery at its origin.

Aiming to examine Netflix’s strategies in its global expansion and based on the debates transnationalization of tv flows, we observe platform’s presence two peripheral markets: Brazil South Korea. In both, find similar tactics, such as licensing commissioning local content partnerships with national production companies. Although identified a recent shift company’s from Latin America towards As...
