The genome of bovine herpesvirus 1 (BHV-1) strains exhibiting a neuropathogenic potential compared to known BHV-1 strains by restriction site mapping and cross-hybridization.

Bovine herpesvirus 1 (BHV-1) strains can be differentiated by their DNA and polypeptide patterns, and by antigenic properties as demonstrated by monoclonal antibodies. We classified the BHV-1 strains according to these data as BHV-1.1, BHV-1.

Development and characteristics of airstepping in chronic spinal cats.

Airstepping, walking-like movements of the hindlimbs, is a commonly observed behavior in chronic spinal animals when they are held vertically. The purpose of this study was to: describe the development of airstepping after spinalization and compare it to the onset of segmental reflexes, characterize the EMG pattern of muscle activity during spontaneous airstepping, and examine the effects of sensory perturbation on the characteristic pattern. Airstepping was analyzed during three conditions of tonic sensory perturbation which included: tail pinching, tape applied to one hindpaw, and immobilization of the ankle and knee in a plaster cast.

Factors to consider in the rehabilitation aspect of burn care.

The rehabilitation of an individual with burns presents a formidable challenge to physical therapists. Early physical intervention and prevention of joint deformity is the key to maximal functional recovery. Throughout the period of rehabilitation, the frequent changes of a patient's condition may require a process of ongoing evaluation and appropriate adjustments in the physical therapy program.

Purification of sea-urchin RNA polymerase II. Characterization by template requirements and sensitivity to inhibitors.

The purification of RNA polymerase II from gastrulae of Paracentrotus lividus is described. The enzyme obtained is homogeneous as judged by electrophoresis under non-denaturing conditions. It is able to transcribe both native high-Mr P.
