OBJECTIVES/HYPOTHESIS Robotic surgery has significant potential in pharyngeal and microlaryngeal surgery. We demonstrate the use of a surgical robot in pharyngeal and microlaryngeal surgery in a cadaver. STUDY DESIGN Six experimental surgical dissections, modeled after commonly performed pharyngeal and microlaryngeal procedures, were performed in a(More)
We evaluated the effects of glycine exposure upon CA1 evoked response in the rat hippocampal slice. Exposure to 10 mM glycine for 16 min, produced rapid neuronal firing and increased orthodromic population spike (PS), followed by loss of CA1 neural transmission. Upon recovery, CA1 orthodromic and antidromic PS regained a mean of only 12 +/- 6% and 8 +/- 5%(More)
Dissection of the musculature in the cervical spines of four cadavers indicated that the semispinalis cervicis and capitis muscles appeared to be the muscles primarily responsible for extension of the cervical spine and head. The minimum force needed to balance a biomechanical model of the cervical spine in the neutral prone position against gravity(More)
—The myriad filter has demonstrated to be a robust countermeasure against the negative effect that impulsive noise has over electronic systems. However, its use is still limited in systems where processing speed is critical, as is the case of radar, sonar, and real-time audio and video processing. This limitation has its roots in the challenges imposed by(More)
Murine nonparenchymal liver cells from various genetic strains isolated by collagenase digestion and differential sedimentation contain both lymphocytes and macrophages. Nonparenchymal liver cells as well as spleen cells, mononuclear blood cells, and peritoneal exudate cells from C3HeB/FeJ mice were tested for natural cytotoxicity against YAC-1 (sensitive(More)
The liver serves as the key organ for the removal and detoxification of bacterial endotoxins that are continously absorbed in small amounts from the gastrointestinal tract. This paper postulates that liver injury impairs this detoxification process leading to further liver damage and systemic effects as well. Evidence is reviewed to support the contention(More)
