Past studies of cold-acclimated bacteria have focused primarily on organisms not capable of sub-zero growth. Siberian permafrost isolates Exiguobacterium sp. 255-15 and Psychrobacter sp. 273-4, which grow at subzero temperatures, were used to study cold-acclimated physiology. Changes in membrane composition and exopolysaccharides were defined as a function(More)
Although the mortality rate for fungal brain abscesses in immunosuppressed patients remains unacceptably high, this figure may be reduced if computed tomography or magnetic resonance imaging scans are performed more promptly in susceptible individuals with seemingly mild intracranial complaints. Earlier presumptive amphotericin B treatment and more timely(More)
OBJECT The authors conducted a study to determine how to avoid emergency postoperative reintubation and its associated morbidity in patients who have undergone multilevel anterior-posterior cervical spine surgery. METHODS In a group effort between the departments of anesthesia and neurosurgery, a protocol was developed to avoid having to reintubate(More)
BACKGROUND Cerebrospinal fluid (CSF) fistulas may occur during anterior cervical surgery performed for the resection of ossification of the posterior longitudinal ligament (OPLL), as OPLL occasionally erodes to and through the dura. These fistulas have been variously managed with gelfoam, dural substitutes sutured in place, fibrin glue, lumbar drains, and(More)
The extracellular polysaccharides (EPS) of six strains of cowpea rhizobia were examined. The strains (MI50A, M6-7B, IRC253) produced polysaccharides containing glucose, galactose and mannose in a molar ratio of 2:1.1:1, 1:1.3:3.1 and 1:1.3:3.5 respectively. Two strains (513-B and Ez-Aesch) produced polysaccharides containing galactose and mannose in a molar(More)
In a series of 81 fractures of the distal end of the radius, 20% had unsatisfactory results. Damage to the ulnar collateral mechanism adversely affects the clinical result despite a good anatomical result. Immobilization of injuries to the ulnar collateral mechanism should be in pronation and ulnar deviation even when there is no significant radial(More)
Radiological examination of the ankles of spina bifida children with flail lower limbs and valgus flat foot deformity has revealed a high incidence of abnormal valgus tilt of the ankle-joint. A study of ankle X-rays of spina bifida children before and after extra-articular subtalar fusion in which the bone graft is removed from the ipsilateral tibia has(More)
The authors evaluated the clinical, radiological, and surgical management of ossification of the anterior longitudinal ligament (OALL) that contributed to dysphagia in a patient with simultaneous cervical ossification of the posterior longitudinal ligament (OPLL). A 57-year-old man presented with increasing dysphagia and moderate myelopathy. Imaging(More)
