Pigmented villonodular synovitis (PVNS) is an uncommon proliferative disease of synovium. We report a 35-year-old male with diffuse form of PVNS of left knee, treated with intraarticular injection of 5 mCi of yttrium-90 (Y-90) silicate colloid consisting of two doses with a 3-month interval between them. During follow-up, the affected knee showed clinical(More)
Progressive systemic sclerosis (PSS) may involve any portion of the gastrointestinal tract, including the colon. Constipation is common in patients with PSS. Cisapride, a benzamide derivative, is a potentially useful agent in the treatment of chronic idiopathic constipation. The effect of cisapride on colonic transit was evaluated in 16 PSS patients by a(More)
Introduction: It has been shown that manganese-enhanced MRI (MEMRI) could be used to perform anterograde neuronal tract tracing in a number of neural systems, including olfactory pathway [1,2]. Recently, laminar structure in the somatosensory cortex could also be imaged by MEMRI [3,4]. The purpose of this study was to determine if MEMRI could distinguish(More)
FP HP Nose Barrel Fig 1.Visualization of soma – totopic maps in the rat S1 cortex. S1 subdivisions of forepaw (FP, yellow), hindpaw (HP, green), barrel (Barrel, purple), and nose (Nose, red) are represented in 2D coronal t-maps (A) and 3D contour (B), which is in an excellent agreement with the somatotopic maps established by electrophysiology (inset) [4].(More)
In previous studies, we have found that electrical stimulation on the hind paw of rats successfully elicit BOLD fMRI activation in several regions of the cerebral cortex. This preliminary study explored the effect of morphine on such kind of footshock-induced brain activity. Rats were anesthetized by alpha-chloralose (20 mg/kg/hr, i.v.) and received(More)
Introduction Rodent neural progenitor cells (NPCs) continually populate the olfactory bulb (OB). Once in the olfactory bulb, these NPCs migrate radially and integrate into preexcising neural circuitry. Based on histological evidence, the NPC distribution within the OB as well as their number can be effected when animals are continually exposed to odors(More)
