ABSTRACT

Studies suggest that the human lumbosacral spinal cord can generate steplike oscillating electromyographic (EMG) patterns, but it remains unclear to what degree these efferent patterns depend on the phasic peripheral sensory information associated with bilateral limb movements and loading. We examined the role of sensory information related to lower-extremity weight bearing in modulating the efferent motor patterns of spinal-cord-injured (SCI) subjects during manually assisted stepping on a treadmill. Four nonambulatory subjects, each with a chronic thoracic spinal cord injury, and two nondisabled subjects were studied. The level of loading, EMG patterns, and kinematics of the lower limbs were studied during manually assisted or unassisted stepping on a treadmill with body weight support. The relationships among lumbosacral motor pool activity [soleus (SOL), medial gastrocnemius (MG), and tibialis anterior (TA)], limb load, muscle-tendon length, and velocity of muscle-tendon length change were examined. The EMG mean amplitude of the SOL, MG, and TA was directly related to the peak load per step on the lower limb during locomotion. The effects on the EMG amplitude were qualitatively similar in subjects with normal, partial, or no detectable supraspinal input. Responses were most consistent in the SOL and MG at load levels of < 50% of a subject's body weight. The modulation of the EMG amplitude from the SOL and MG, both across steps and within a step, was more closely associated with limb peak load than muscle-tendon stretch or the velocity of muscle-tendon stretch. Thus stretch reflexes were not the sole source of the phasic EMG activity in flexors and extensors during manually assisted stepping in SCI subjects. The EMG amplitude within a step was highly dependent on the phase of the step cycle regardless of level of load. These data suggest that level of loading on the lower limbs provides cues that enable the human lumbosacral spinal cord to modulate efferent output in a manner that may facilitate the generation of stepping. These data provide a rationale for gait rehabilitation strategies that utilize the level of load-bearing stepping to enhance the locomotor capability of SCI subjects.

ABSTRACT

The objective of this study is to determine the prevalence of cervical lesions in a population of young adults. This study took into account 897,900 pap smears kindly provided by the cytopathology division at the University of Mississippi Medical Center. These cases were subdivided into three different groups based on age. Group one represents the age population of 0-17, group two represents the age population of 18-34, and group three represents the age population of 35 and higher. Seven different parameters were evaluated in this study. These include negative: unsatisfactory, atypia, CIN I, CIN II, CIN III, and invasive carcinoma. Data obtained from this study suggests that cervical lesions among young teenagers were found to be significant and our observations recommend that this population be screened and evaluated on a regular basis. The results of this study conclude that cervical lesions are significant among young adults. This age group would benefit from education and routine screening. In addition early sexual activity, multiple partners, and infectious diseases were noted in cases with cervical cancer. This could be due to the high occurrences of SIL in young adults. Screening of this age group is highly recommended for those young adults at "high risk."

ABSTRACT

Whole-cell lysates and proteinase K-extracted lipopolysaccharide (LPS) of 19 strains of the group eugonic fermenter-4 (EF-4) were analyzed by electrophoresis and protein immunoblotting. These strains were isolated from dog- and cat-bite abscesses in human beings, ferret and human gastric lesions, and cat-lung infections. These strains represent 2 biovar groupings; EF-4a biovars ferment glucose and possess arginine dihydrolase activity, whereas EF-4b biovars do not. Electrophoresis of whole-cell lysates could distinguish between these biovars groups. Electrophoresis of LPS extracts revealed that all strains of EF-4 possess smooth chemotypes. Two strains of EF-4a reacted weekly in protein immunoblots and revealed distinct LPS profiles. These studies suggests that subgroups of EF-4 biovars may exist.
