OBJECT Vasospasm is one of the leading causes of morbidity and death following aneurysmal subarachnoid hemorrhage (SAH). Many patients suffer devastating strokes despite the best medical therapy. Endovascular treatment is the last line of defense for cases of medically refractory vasospasm. The authors present a series of patients who were treated with a(More)
OBJECT Approaching the C2-3 disc level is challenging because of its location behind the mandible and the vital neurovascular structures overlying the area. The purpose of this study was to illustrate in a stepwise fashion the microsurgical anatomy of the submandibular approach to the C2-3 disc. METHODS Ten adult formalin-fixed cadaveric specimens (20(More)
OBJECT The authors undertook this cadaveric and angiographic study to examine the microsurgical anatomy of the V₃ segment of the vertebral artery (VA) and its relationship to osseous landmarks. A detailed knowledge of these variations is important when performing common neurosurgical procedures such as the suboccipital craniotomy and the far-lateral(More)
OBJECTIVE Drawbacks of the far-lateral approach to the lower clivus and pontomedullary region include the morbidity of a large incision extending into the cervical musculature and tedious exposure of the vertebral artery (VA), particularly when performing the transcondylar and transtubercular extensions. The authors describe a minimally invasive alternative(More)
One of the most challenging issues in the design of system for Wireless Sensor Networks (WSN) is to keep the energy consumption of the sensor nodes as low as possible. Many localization systems require that the nodes keep the transceiver active during a long time consuming energy. In this work we propose a scheme to reduce the energy consumption of the(More)
We evaluated the comparative plasma and abomasal fluid disposition kinetics of albendazole (ABZ) and its metabolites in calves either grazing on pasture or fed a grain-based concentrate diet. Six male Holstein calves (weight 180 to 200 kg) were allowed to graze on lush pasture for three weeks before intraruminal administration of ABZ at 10 mg kg-1(pasture(More)
The effects of two doses of polyestradiol phosphate on lecithin:cholesterol acyltransferase activity and on liver and plasma cholesterol levels have been studied on female and male rats. Both treatments increased the hepatic content of esterified cholesterol, but the LCAT activity expressed as a percentage of cholesterol esterification was unaltered. The(More)
BACKGROUND Currently, there is no prioritization scale available to distinguish those patients with pituitary tumors who require urgent surgical intervention from those who are candidates for elective treatment. OBJECTIVE To develop a classification system that can help primary care physicians, endocrinologists, neurosurgeons, ancillary support staff, and(More)
