Monocyte chemoattractant protein-1 is produced by Schwann cells during Wallerian degeneration of a peripheral nerve and contributes to a selective accumulation of macrophages in the degenerating segment. An in vitro preparation has been developed to analyze the molecules from axons and non-neuronal cells in nerves that stimulate an increased production of… (More)
The potential to use Schwann cells (SCs) in neural repair for patients suffering from neurotrauma and neurodegenerative diseases is well recognized. However, significant cell death after transplantation hinders the clinical translation of SC-based therapies. Various factors may contribute to the death of transplanted cells. It is known that prolonged… (More)
The neuropoietic cytokines and their cytoplasmic signaling molecules contribute to axotomy-induced events in the nerve cell body that are beneficial to axonal regeneration. Previous studies have revealed a paradox in that, in vivo, suppressor of cytokine signaling (SOCS3) is induced in axotomized primary sensory neurons which are in a growth mode but, in… (More)
RATIONALE Microbubbles conjugated with targeting ligands are used as contrast agents for ultrasound molecular imaging. However, they often contain immunogenic (strept)avidin, which impedes application in humans. Although targeting bubbles not employing the biotin-(strept)avidin conjugation chemistry have been explored, only a few reached the stage of… (More)
BACKGROUND Professional societies use metrics to evaluate medical schools' policies regarding interactions of students and faculty with the pharmaceutical and medical device industries. We compared these metrics and determined which US medical schools' industry interaction policies were associated with student behaviors. METHODS AND FINDINGS Using survey… (More)

Intracranial endodermal cysts are most commonly located in the posterior cranial fossa anterior to the brainstem. We report a rare case of an endodermal cyst of the posterior fossa located dorsal to the brainstem and is to our knowledge the only other such case reported in the literature.
A 26-year-old male presented with acute mid-thoracic back pain following a witnessed grand mal seizure. There was no trauma and the patient was on steroids for systemic lupus erythematosus. X-rays and CT scans of the thoracic spine revealed compression fractures at T5 and T6, with 50 % loss of vertebral height and kyphosis. He underwent percutaneous… (More)
