Development of pharmacological strategies for the control of locomotion in patients with spinal cord injury or disease requires an understanding of the neuroactive substances involved in the activation of the spinal cord neural systems for the control of locomotion. Studies using the in vitro preparations of the lamprey, frog embryo, and newborn rat(More)
The c-fos immunohistochemical method of activity-dependent labeling was used to localize locomotor-activated neurons in the adult cat spinal cord. In decerebrate cats, treadmill locomotion was evoked by electrical stimulation of the mesencephalic locomotor region (MLR). Spontaneous or MLR-evoked fictive locomotion was produced in decerebrate animals(More)
The protein truncation test (PTT) is a mutation-detection method used to scan for premature termination (nonsense) mutations. PCR amplification of the DNA or mRNA source material is performed using forward primers containing a T7-promoter sequence and translation initiation signals such that the resultant products can be transcribed and translated in vitro(More)
In newborn English Infants, the predominant faecal bacteria were coliforms and bacteroides, as shown by Gram film, culture, and gas-liquid chromatography, whether they were bottle fed or exclusively breast fed. This contrasted with bifidobacterial predominance in faeces from breast-fed Nigerian infants. Presumably environmental factors other than exclusive(More)
This paper describes a system that automatically transforms a PDDL encoding, calls a planner to solve the transformed representation, and translates the solution back into the original representation. The approach involves counting objects that are indistinguishable, rather than treating them as individuals, which eliminates some unnecessary combinatorial(More)
One hundred and twenty-three total colonoscopies were performed on 115 children with ages ranging from 3 months to 16 years. The major indications were suspected inflammatory bowel disease and unexplained rectal bleeding. Ninety-seven per cent of all procedures were carried out with sedation only. Adult colonoscopes were used in most of the patients but in(More)
