A morphologically defined group of peptidergic neurons in the CNS of the hermaphroditic snail, Lymnaea stagnalis, is concerned with the control of a very specific element of male sexual behavior. These neurons are located in the anterior lobe of the right cerebral ganglion (rAL). By using chronically implanted electrodes, we show that the rAL neurons are selectively active during eversion of th...

in this paper, two patients with severe dysphagia and esophageal stricture secondary to epidermolysis bullosa are presented and discussed. they are siblings of an affected family. primary resection and anastomosis had been performed previously in both patients, but dysphagia had recurred. we treated these patients with free jejunal graft to the esophagus with excellent results. both patients ar...

Current evidence suggests that there are three sphincters that regulate the flow of chyme from stomach to the duodenum. We investigated the hypothesis whether a fourth 'physiologic sphincter' exists at the duodeno-jejunal junction. The pressure response of the jejunum, duodeno-jejunal junction and duodenum to individual balloon distension of the jejunum and duodenum was recorded in 28 healthy s...

Development of patellofemoral pain syndrome (PFPS) is considered to be multifactorial. The aims of this systematic review were to (i) summarise and critique the body of literature addressing kinematic gait characteristics associated with PFPS; and (ii) provide recommendations for future research addressing kinematic gait characteristics associated with PFPS. A comprehensive search of MEDLINE, E...

The purpose of this study was to compare in vivo segmental foot motion during walking and step descent in patients with midfoot arthritis and asymptomatic control subjects. Segmental foot motion during walking and step descent was assessed using a multi-segment foot model in 30 patients with midfoot arthritis and 20 age, gender and BMI matched controls. Peak and total range of motion (ROM), ref...

Trachomatous Entropion with Trichiasis The procedure presented by Stallard (1958) as "tarsal paring and eversion" has, in my experience, been most satisfactory and I believe that it is the best technique to be adopted in any area of the world where the incidence of trachomatous entropion is still high. In the course of 559 operations of "tarsal paring and eversion" which I have performed in Add...

BACKGROUND The purpose of this study was to establish the effect of simple non moulded flat based insoles on three-dimensional foot motion during normal walking. Excessive foot pronation is considered a major contributing factor to lower limb injuries. Moulded foot orthoses have been shown to decrease maximum foot eversion. Simple insoles are widely used in clinical practice as an alternative t...
