Extra-hepatic bile duct injury from blunt abdominal trauma is uncommon. Complete traumatic transection of the common bile duct (CBD) with subsequent complication of a choledochoduodenal fistula is extremely rare and only a handful of reports are found in the medical literature. We describe a 20-year-old male patient who presented with a complete transection of the CBD following blunt abdominal ...

Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...

Olfactory ensheathing cells (OECs) prepared from the olfactory bulbs of adult transgenic Sprague Dawley (SD) rats expressing green fluorescent protein (GFP) were transplanted into a dorsal spinal cord transection lesion of SD rats. Five weeks after transplantation, the cells survived within the lesion zone and oriented longitudinally along axons that bridged the transection site. Although the h...

It has been proposed that the responses of the cerebral circulation to hypoxia, hypercapnia and hypotension may be partially mediated by an autonomic reflex with receptors in the carotid body or sinus serving as sensors and the efferent limbs being the 7th cranial nerves. Transection of the 7th cranial nerve has been reported to impair the cerebral circulatory response to isolated chemoreceptor...

Central Nervous System (CNS) regeneration and repair mechanism are two important aspects of functional recovery in the adult central nervous system following brain and spinal cord injury. Following olfactory tract transection in neonatal rats, functional connectivity between the olfactory bulb and the piriform cortex gets re-established by 120 days. The recovery of the dendritic morphology was ...

During the development of central nervous system, radial glial cells support target-specific neuronal migration. We recently reported that after implantation of chitosan channels with complete spinal cord transection, the tissue bridging the spinal cord stumps contained axons and radial glial cells. The purpose of this study was to clarify the role of the radial glial cells in the tissue bridge...

Minimally invasive liver resection (MILR) has evolved considerably in the past decade. Safe hepatic parenchymal transection, has been one of the technical hurdles that has become evident during the growth of MILR. Advances in technology have now made safe liver transection a reality allowing resections of greater magnitude. In this review, the precoagulation approach is described in both method...

After spinal transection in ammocoetes (lamprey larvae) 4 to 5 years old, functional recovery is accompanied by a limited regeneration in which axons grow as far as 5 millimeters beyond the scar. In axotomized giant interneurons labeled intracellularly with horseradish peroxidase 16 to 120 days after transection, 74 percent of regenerating neurites grew in their normal projection pattern, rosta...

In this paper, a new practical implementation of a person verification system using features of longitudinal section and transection and other facial, rotation compensated 3D face image, is proposed. The approach works by finding the nose tip that has a protrusion shape on the face. In feature recognition of 3D face image, one has to take into consideration the orientated frontal posture to nor...

CONTEXT Isolated pancreatic transection is a rare but well-recognized complication following blunt trauma of the abdomen. Diagnosis at presentation may be difficult and delayed due to subtle initial symptoms and evolving nature of the injury. CASE REPORT We describe an isolated complete pancreatic transection in a 14-year-old female secondary to a previously unreported and highly unusual mech...
