BACKGROUND The vicinity of brainstem and cranial nerves as well as the limited operative working space make clip ligation of posterior inferior cerebellar artery (PICA) aneurysms challenging. The small caliber of the PICA and the broad neck often associated with these aneurysms also create challenges in preserving this artery during treatment. Few data(More)
When the fluorescence signal of a dye is being quantified, the staining protocol is an important factor in ensuring accuracy and reproducibility. Increasingly, lipophilic dyes are being used to quantify cellular lipids in microalgae. However, there is little discussion about the sensitivity of these dyes to staining conditions. To address this, microalgae(More)
Classically, small molecule antagonists have targeted membrane bound receptors and intracellular enzyme targets. While this drug discovery strategy is extremely successful, the number of new chemical entities in the pharmaceutical pipeline is diminishing and complementary strategies are in need. A particularly attractive therapeutic strategy is to(More)
BACKGROUND To better understand the longitudinal trend in the proportion of techniques employed for cerebral aneurysm treatment, we reviewed our experience with 2253 patients over the last 11 years. METHODS We reviewed data in our prospective aneurysm database for all consecutive patients treated from January 1998 through December 2009. Data regarding(More)
OBJECTIVE Ophthalmic aneurysms present unique challenges to a vascular team. This study reviews the 16-year experience of a multidisciplinary neurovascular service in the treatment, complications, outcomes, and follow-up of patients with ophthalmic aneurysms from 1990 to 2005. METHODS A retrospective analysis of prospectively collected data of 134(More)
OBJECTIVE Endovascular retrograde suction decompression with balloon occlusion of the internal carotid artery is a useful adjunct in the surgical treatment of ophthalmic aneurysms. This technique helps establish proximal control, facilitates intraoperative angiography, and may aid dissection by evacuating blood and softening the aneurysm. Although the(More)
Traumatic intracranial aneurysms are rare lesions that are relatively more common in the pediatric population. Proximal traumatic aneurysms occur near the skull base. Direct surgical repair of these lesions is difficult due to the anatomically confined area, clinical status of a head injury patient, and the transmural nature of the injury. These lesions(More)
BACKGROUND Contour deformities after massive weight loss are diverse and often severe in nature. Current progress has necessitated a valid, accessible, and comprehensive rating system that correlates appearance and appropriate surgical treatment. Presently, no existing rating system addresses the breadth and variety of deformities that can occur or allows(More)
Nerve growth factor (NGF) is critical for the proliferation, differentiation, and survival of neurons through its binding to the p75(NTR) and TrkA receptors. Dysregulation of NGF has been implicated in several pathologies, including neurodegeneration (i.e., Parkinson's and Alzheimer's diseases) and both inflammatory and neuropathic pain states. Therefore,(More)
This work investigated a top-lit open microalgae bioreactor that uses a gas-lift system to enable deeper production depths, thereby significantly reducing the footprint. Growth of Scenedesmus sp. in a one-meter deep system by sparged with 6% CO2-enhanced air was evaluated. The results gave comparable volumetric biomass productivity (0.06 g(dw) L(-1)(More)
