BACKGROUND: Outpatient craniotomy, biopsy, and spinal decompression have been performed at our center for more than a decade. Early feasibility studies suggest that they are safe, successful, cost-effective, and well-tolerated by patients. However, a largescale study of this magnitude has not been performed. OBJECTIVE: To characterize postoperative complications and the rate of successful disch...

In London on September 11-12, 2000, the Royal Society—the independent scientifi c academy in Britain, the counterpart to the U.S. National Academy of Science—hosted a discussion meeting on the “Origins of HIV and the AIDS epidemic.” The brochure about the meeting gave this synopsis: “HIV-1 and HIV-2 causing AIDS are new human viruses of animal origin. When, how and why these cross-species infec...

Introduction Neurodisability is probably the most significant contributor to chronic surgical disability in African children. It involves primarily hydrocephalus (HC) and spina bifida (SB), which can occur in isolation or together. Other causes of neurodisability include encephaloceles, which are part of the spectrum of neural tube defects (NTDs). True cerebral palsy is primarily nonsurgical, a...

Three new Block Code Diversity combing schemes for digital transmission over a Rayleigh fading channel have been proposed. It has been shown that improved performance in term of probability of error versus signal to noise ratio has been obtained using soft-decision Viterbi decoding together with diversity techniques. Simulation results have been included to verify the performance of the propose...

A new and the first mammal fossil locality from the Zagros Basin of Iran is reported here. The fossil locality, known as Dimeh, is located in the Lorestan province, west of Iran. The fauna includes abundant bovid cranial remains, mostly representing boselaphines and palaeoryxoids, as well as gazelles and spiral horned antelopes. Hipparionine horses similar to Hippotherium group are also represe...

Typically, mature neurons are polarized cells composed of a dendritic arbor and a single axon (reviewed by Craig and Banker, 1994; Higgins et al., 1997). This polarity becomes apparent early during development when the neuron extends a growth cone to form a single unbranched axon (reviewed by Goodman, 1996; Goodman and Tessier-Lavigne, 1997; Mueller, 1999). In some neuronal populations collater...
