(2) Based on our results, we propose the following hypotheses for the neurochemical mechanisms of motion sickness: (1) the histaminergic neuron system is involved in the signs and symptoms of motion sickness, including vomiting; (2) the acetylcholinergic neuron system is involved in the processes of habituation to motion sickness, including neural store mechanisms; and (3) the catecholaminergic neuron system in the brain stem is not related to the development of motion sickness.
(3) The examination of the standard waves' amplitude and latency of the brain stem auditory evoked response (BAEP) was performed in 20 guinea pigs (males and females, weighing 250 to 300 g).
(4) A previous trial into the safety and feasibility of using bone marrow stem cells to treat MS, led by Neil Scolding, a clinical neuroscientist at Bristol University, was deemed a success last year.
(5) Proliferation of quiescent hematopoietic stem cells, purified by cell sorting and evaluated by spleen colony assay (CFU-S), was investigated by measuring the total cell number and CFU-S content and the DNA histogram at 20 and 48 hours of liquid culture.
(6) The last stems from trends such as declining birth rate, an increasingly mobile society, diminished importance of the nuclear family, and the diminishing attractiveness of professions involved with providing maintenance care.
(7) Following BHT administration, the alveolar stem cells (type II pneumocytes) proliferate and differentiate according to a biphasic pattern, with proliferative peaks at d 3 and 7.
(8) In testing the contribution of the long, curved stem to the torsional stability of uncemented prostheses by comparing it with other stems, the long, curved stem was the most stable, followed by a shorter straight stem, and a short, proximally curved stem.
(9) For example, stem pairing with a sequence other than wild-type resulted in normal protein binding in vitro but derepression of protein synthesis in vivo.
(10) These results indicate that this population (approximately 0.1% of bone marrow) may contain the pluripotent hematopoietic stem cell.
(11) Brain-stem CBF varied the most but did not correlate with clinical signs of brain-stem dysfunction.
(12) We infer from these results that endotoxin ameliorates the cyclical changes in blood cell counts by regulating hematopoietic proliferative activity at the stem cell level.

(15) This has stemmed from an inadequate understanding of the mechanisms involved in the formation and propagation of this condition.
(16) We therefore think that the detailed examination of CALLA(-) non-T non-B ALL cells using myeloid specific antibodies is helpful in clarifying the characteristics of myeloid precursors and the common bipotential stem cell of lymphoid and myeloid progenitors.
