| genetic and biochemical characterization of the thymidine kinase gene from herpesvirus of turkeys. | the thymidine kinase gene encoded by herpesvirus of turkeys has been identified and characterized. a viral mutant (atr0) resistant to 1-beta-d-arabinofuranosylthymine was isolated. this mutant was also resistant to 1-(2-fluoro-2-deoxy-beta-d-arabinofuronosyl)-5-methyluracil and was unable to incorporate [125i]deoxycytidine into dna. the mutant phenotype was rescued by a cloned region of the turkey herpesvirus genome whose dna sequence was found to contain an open reading frame similar to that fo ... | 1989 | 2724415 |
| [imbecility of moderate degree in schoolchildren]. | the data of an experimental psychological investigation and self-service skills acquisition are presented for children with slight imbecility in three age groups: junior, middle and senior school-age. the peculiarities of the course of mental functions are discussed and potential intellectual capacities assessed in terms of the social and labor rehabilitation. | 2009 | 2728743 |
| biomechanical considerations on some postoperative problems of directly anchored total hip replacements. | uncemented total hip replacements have resulted in a higher incidence of postoperative complaints than cemented ones. the theoretical explanation of these not well defined discomforts is based on the differences of the stress and strain fields around the distal portions of the femoral components. while the noncemented stems are press-fitted and most of them tapered distally, thus creating hoop stresses and strains in the surrounding cortical bone, the shrinkage of the cement prevents these mecha ... | 2009 | 2738082 |
| human gastric lipase. the n-terminal tetrapeptide is essential for lipid binding and lipase activity. | human gastric lipase subjected to limited tryptic proteolysis lost its ability to hydrolyze emulsified long-chain triacylglycerol. activity against a water-soluble substrate was however retained, indicating that proteolysis did not affect the active site. sequence analysis revealed that trypsin specifically cleaved the linkage between lysine-4 and leucine-5. this cleavage rendered the enzyme unable to bind to emulsified triacylglycerol particles, e.g. human milk fat globules. we suggest that the ... | 1989 | 2753032 |
| effects of systemic morphine upon a delta- and c-fibre evoked activities of subnucleus reticularis dorsalis neurones in the rat medulla. | the effects of intravenous administration of morphine were examined on a delta- and c-fibre evoked activities of subnucleus reticularis dorsalis (srd) neurones in the rat medulla. this region may have an important role in nociception since srd neurones exhibit whole body receptive fields from which they can be activated preferentially or exclusively by noxious stimulation. the present study demonstrates that morphine can depress the c-fibre evoked responses of srd neurones in a dose-related (3-1 ... | 1989 | 2753082 |
| identification and characterization of an 8-kd peptide stimulating late erythropoiesis. | chronic renal failure is often associated with severe anemia, subnormal levels of erythropoietin (epo), and the presence of erythropoietic inhibitors. we studied an anephric patient with polycystic kidney disease maintaining a hemoglobin level of 13-14 g. biochemical, endocrine, and hematological parameters were all within normal limits. epo levels examined on two occasions during the clinical investigation were found to be low to subnormal. plasma of this patient supported human bone marrow ery ... | 1989 | 2753086 |
| the dispersion of echinococcus granulosus in the intestine of dogs. | we studied the dispersion of adult echinococcus granulosus in the intestine of experimentally infected dogs at 2 scales of habitat use. on a coarse scale, worms were found most frequently in the anterior third of the small intestine. on a fine scale, clumps or aggregations, typically of 4-5 worms in an area of 12 mm2, occurred throughout the anterior two-thirds of the intestine. the most likely proximate cause of aggregative behavior is attraction between individual worms. there are at least 2 e ... | 1989 | 2760768 |
