introduction the brachial plexus, a complex network of nerves, innervates to the upper limbs. variation in the course of the nerves in the upper limb is common. case presentation this paper describes two cases of upper limb variations in a cadaver dissected at lorestan university of medical sciences. in the first variation, the median nerve in the arm has a different route, so that the median m...

Background: Two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (OP) and abductor pollicis brevis (APB). However, Riché-Cannieu communicating branch (RCCB) may limit the use of these muscles in electrodiagnosis. This condition is confusing in the case of median nerve injuries. This study was conducted to evaluate the prevalence of RCCB. &...

OBJECTIVE: Diabetes mellitus is one of the most common endocrine diseases with micro-vascular complications and is a common cause of polyneuropathy. We studied the effect of enalapril on electrophysiologic criteria and clinical symptoms of patients with type II diabetes and sensory neuropathy. MATERIALS AND METHODS: A double blind study was conducted on 45 Patients with type II diabetes and ne...

Using previously published data from flume studies, we test a new approach for quantifying the effects of sediment supply (i.e., bed material supply) on surface grain size of equilibrium gravel channels. Textural response to sediment supply is evaluated relative to a theoretical prediction of competent median grain size (D950). We find that surface median grain size (D50) varies inversely with ...

— In this paper we consider multiperiod médian problems on networks, in which multiple facilities are to be located. In order to reduce the choices available for the location of the facilities a number of important properties are studied. For the absolute multiperiod médian the vertex optimality property is established^ and for continuous multiperiod problems, the set of vertices and middle poi...

The colourful simplicial depth (CSD) of a point x ∈ R relative to a configuration P = (P , P , . . . , P ) of n points in k colour classes is exactly the number of closed simplices (triangles) with vertices from 3 different colour classes that contain x in their convex hull. We consider the problems of efficiently computing the colourful simplicial depth of a point x, and of finding a point in ...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...
