neonatal hyperammonaemia with complete absence of liver carbamyl phosphate synthetase activity.two newborn infants, male (a) and female (b), with lethal hyperammonaemia are described in the same family. in both, symptoms started on the second day of life. lethargy and hypotonia were the most prominent initial findings and were followed by convulsions and coma. in both, blood ammonia levels rose to 570 mumol/u (795 microgram/100 ml) a few hours before death, which occurred on the third and fourth day of life respectively. assay of liver urea cycle enzymes in baby b showed a complete absenc ...1992206210
kinetic studies on the reactions catalyzed by chorismate mutase-prephenate dehydrogenase from aerobacter aerogenes.steady-state kinetic techniques have been used to investigate each of the reactions catalyzed by the bifunctional enzyme, chorismate mutase-prephenate dehydrogenase, from aerobacter aerogenes. the results of steady-state velocity studies in the absence of products, as well as product and dead-end inhibition studies, suggest that the prephenate dehydrogenase reaction conforms to a rapid equilibrium random mechanism which involes the formation of two dead-end complexes, viz, enzyme-nadh-prephenate ...1978206281

fast-neutron irradiation of glioblastoma multiforme. neuropathological analysis.various modes of therapy, alone or in combination, have had little effect in improving the survival of patients with glioblastoma multiforme. recently, in a pilot study, 34 patients with glioblastoma were treated by fast-neutron-beam irradiation of the whole brain. following treatment, the patients became steroid-dependent and pursued a gradual downhill course with increasing obtundation. although there was no improvement in the length or quality of survival of these patients, neuropathological ...1991207833
differential effects of isolated lipoproteins from normal and hypercholesterolemic rhesus monkeys on cholesterol esterification and accumulation in arterial smooth muscle cells in culture.whole serum obtained from hypercholesterolemic rhesus monkeys was found to stimulate cholesterol esterification and cholesteryl ester accumulation in rhesus monkey arterial smooth muscle cells in culture to a significantly greater extent than normocholesterolemic serum. this was true even when the cholesterol concentration of the culture medium was equalized. isolation and characterzation of the low density lipoproteins (ldl) from rhesus monkeys indicated that the ldl from hypercholesterolemic a ...1978208631
estimating adrenal cortical function in dogs with acth.the peripheral blood response to intramuscular injection of 10 units acth in dogs was investigated because no experimental evidence for the standardization of this procedure for clinical use was available. following the injection of acth in sodium chloride solution, neutrophilia, monocytosis, eosinopenia, and lymphopenia occurred. with the exception of eosinopenia, the greatest change in the concentration of each cell type in peripheral blood occurred between 2 and 4 hours post injection. the ma ...1978208814
sources of variation in the output of locust spiracular motoneurones receiving common synaptic driving.1. the closer muscles of the left and the right spiracles of a thoracic segment are both innervated by two motoneurones, which spike in a variety of patterns during expiration. this paper seeks to explain the origin of these patterns. 2. no direct coupling between the two motoneurones is revealed. in an isolated thoracic ganglion both motoneurones spike at different frequencies with no tendency for their spikes to become synchronized. 3. the two closer motoneurones in one segment receive common, ...1990209120

alterations in the expression of the cytomegalovirus-induced cytopathogenic effect in fibroblasts by aflatoxin b1.aflatoxin b1 has been shown both to promote and to alter the expression of the cytopathogenic effect observed when human fibroblasts are challenged with human cytomegalovirus (cmv). although the cells become round, as is the characteristic effect of this virus on fibroblasts, multinucleate cells are seen to arise from cell fusion within 48 h after virus addition.1978218602
phosphatases in the central nervous system of spiders (arachnida, araneae).the central nervous systems of web-building spiders (araneidae, agelenidae) and hunting spiders (lycosidae, salticidae) were tested for non-specific and specific phosphatases. acid phosphatase exhibited weakly to moderately positive reactions in the neuronal cell bodies and in the neuropile fibre mass of all species investigated. alkaline phosphatase could only be demonstrated in the external and internal neural lamellae of the brain and ventral cord of several specimens of the araneid species i ...1985218910
[blood transfusion and viral diseases. recent acquisitions concerning viral hepatitis viruses, cytomegaloviruses and epstein-barr virus].in recent years, an increasingly clear picture has been formed of the virus-induced syndromes that may follow a blood transfusion or the use of blood derivatives. up to about 10 years ago, post-infusion infection was predominantly due to serum hepatitis. blumberg's discovery of hbsag (formerly known as australia antigen) has made it possible to check and prevent viral hepatitis, type b, and to recognise such distinct forms as the mononucleosis-like syndrome caused by cytomegalic virus, infectiou ...1979219399
