Arterial thoracic outlet syndrome.

Thoracic outlet syndrome (TOS) is used to describe the constellation of symptoms arising from neurovascular compression of the thoracic outlet. The structures passing through the thoracic outlet include the subclavian artery, subclavian vein and trunks of the brachial plexus. Patients may experience symptoms related to compression of any one or various combinations of these structures.

Relative contribution of individual versus combined functional imaging studies in predicting seizure freedom in pediatric epilepsy surgery: an area under the curve analysis.

Objective: The goal of this study was to evaluate the predictive value and relative contribution of noninvasive presurgical functional imaging modalities based on the authors' institutional experience in pursuing seizure-free surgical outcomes in children with medically refractory epilepsy.

Methods: This was a retrospective, single-institution, observational cohort study of pediatric patients who underwent evaluation and surgical treatment for medically refractory partial epilepsy between December 2003 and June 2016. During this interval, 108 children with medically refractory partial epilepsy underwent evaluation for localization and resective epilepsy surgery.

NMR structure/function relationships of peptides corresponding to the C1B1 Region of PKC gamma.

The region (101-112) of C1B domain in PKC gamma plays a crucial role in the activation of the enzyme and subsequent gap junction inhibition. Substitution studies on peptides correlating to the C1B region show that a flexible structure and ability to be phosphorylated on serine 109 are critical for this purpose.
