| [study of the dynamics of acid formation in the stomachs of dogs under the influence of thyroidin by the method of intragastric ph-graphy]. | intragastral ph-graphy was applied to the study of the dynamics of acid production in the stomach of dogs with fistulae of the fundal portion of the stomach out of and during digestion, and also before and after the thyroidin prescription. biphasic character of the changes in acid production in the stomach under the effect of the hormonal preparation was revealed. | 1978 | 31210 |
| [levels of testosterone and dihydrotestosterone in guinea pig sex canals during embryonic life]. | at the undifferentiated stage, testosterone and dihydrotestosterone levels were comparable in sexual ducts of both sexes. an hormonal sexual dimorphism appeared at the time of differentiation: while testosterone rapidly decreased in the female ducts, it considerably increased in those of the male. testosterone rather than dht seems to be responsible for the wolffian duct stabilization in the male foetus. | 1978 | 95894 |

| occurrence and distribution of western equine encephalomyelitis in florida. | research and surveillance programs relating to the occurrence and distribution of western equine encephalomyelitis virus in florida, conducted between 1955 and 1976, suggest that the virus is (1) an endemic arbordae, (2) transmitted in a continuous cycle throughout the year by culiseta melanura mosquitoes, and (3) restricted to fresh water swamps and waterways in central, north, and northwest florida. | 1978 | 23372 |
| [formation of cutaneous nerve trunks in the chick. ultrastructural and quantitative analysis]. | in chick skin structuration of nervous trunks takes place at 14-15 days of incubation, at the time of formation of the adult pattern of cutaneous innervation. at this same stage, myelogenesis begins, but develops mainly after hatching: only 4% of axons are myelinated at hatching, 40% in 6-week old chickens and 60% in adults. this "critical" stage (14-15 days of incubation) apparently corresponds to the stabilization of cutaneous nerve supply. | 1978 | 96985 |
| [nature of the mutations that determine the ability of bacillus subtilis a-50 to sporulate at high glucose concentrations in the medium]. | the ability of bacillus subtilis a-50 to sporulate in the medium containing high glucose concentrations is caused by at least two mutation types: pts mutations and cat (or tgl) mutations, both of them affecting differently the level of alkaline proteinase synthesis. the decrease of the level of enzyme activity in the case of pts mutation (glur3 mutant) occurs at the expense of glucose transport disturbance. the mutation cat (tgl) (mutant glur5) causes the increase in enzyme synthesis at the expe ... | 1978 | 97172 |
| biosynthesis of delta-aminolevulinic acid by blue-green algae (cyanobacteria). | when levulinic acid, a competitive inhibitor of delta-aminolevulinic acid dehydratase, was added to growing cultures of blue-green algae (cyanobacteria), delta-aminolevulinic acid was excreted into the medium and cell growth was inhibited. | 1978 | 97274 |
| amino acid sequence of beta-galactosidase. viii. sequence of the nh2-terminal segment, cnbr peptides 1 to 9, residues 1 to 377. | the amino acids in 9 cyanogen bromide peptides have been placed in sequence starting from the nh2 terminus. the peptides account for residues 1 to 377 of the whole protein and include the largest (cnbr7, 119 residues) and the smallest (cnbr1, 2 residues) of the cyanogen bromide peptides. this region contains only 3 of the 20 lysine residues in the polypeptide chain. a high proportion of charged groups are present (28 of 66 arginine, 28 of 60 glutamic acid, and 24 of 65 aspartic acid residues). | 1978 | 97295 |

| direct administration of methotrexate into the central nervous system of primates. part 1: distribution and degradation of methotrexate in nervous and systemic tissue after intraventricular injection. | levels of methotrexate (mtx) measured by both 3h radioactivity and dihydrofolate reductase assays were determined in cerebrospinal fluid (csf), plasma, urine, and both neural and non-neural tissues at varying times after a single intraventricular injection into cynomolgus monkeys (macaca fascicularis). clearance of the mtx from csf was rapid after injection. a relatively constant level of 3hmtx was reached in plasma 2 1/2 hours after injection, and about 30% of the 3hmtx dose was excreted in the ... | 1978 | 96228 |
| the pattern of sporulation in anabaena circinalis and comments on the role of heterocysts in sporulation in blue-green algae. | cells between two intercalary heterocysts differentiate at random into spores in a. circinalis. one or more cells, which fail to transform into spores, are present between the two adjacent spores, and these cells disorganize later. a critical c:n ratio regulates sporulation and heterocyst formation. during sporulation the reductive ability of the heterocyst gradually diminishes. it is concluded on the basis of this and other evidence that sporulation is regulated by interactions between heterocy ... | 1978 | 97869 |

| formylation of initiator trna methionine in procaryotic protein synthesis: in vivo polarity in lactose operon expression. | eucaryotic and procaryotic organisms differ in two aspects of their translation machinery: polycistronic messengers are expressed as a sequence of individual proteins only in procaryotes, and the initiation of protein synthesis proceeds with an initiator trna which is found to be modified (formylated) in procaryotes and not in eucaryotes. in the present study, we show that formylation is required in vivo for the coordinate expression of the escherichia coli lactose operon. our experiments are co ... | 1978 | 98518 |
| the effects of sodium nitroprusside and trimethaphan camsylate on cerebral blood flow in rhesus monkeys. | hemispheric cerebral blood flow was measured in the rhesus monkey before and after infusion of the hypotensive agents sodium nitroprusside and trimethaphan camsylate. the intracarotid injections of 133xe was utilized, and flow was calculated by the "flow initial" technique. cerebral blood flow did not change significantly with the administration of trimethaphan camsylate. however, with a small reduction in blood pressure (10.6%) during the administration of sodium nitroprusside, the cerebral blo ... | 1978 | 98729 |
| location of the genes for human heavy chain immunoglobulin to chromosome 6. | immunoglobulin synthesis was examined in 31 man-mouse hybrid clones produced by fusing rag mouse cells with human lymphoid cells. cells were grown in serum-free medium containing [(14)c]leucine and a (14)c-labeled amino acid mixture. spent medium was dialyzed, concentrated, and subjected to radioimmunoelectrophoresis. eighteen clones were found to produce material that gave a radiolabeled precipitin line with anti-human igg (gamma-chain specific). production of material which was indistinguishab ... | 1978 | 98768 |

| vascular dynamics of an experimental cerebral arteriovenous shunt in the primate. | an arteriovenous fistula which shunted arterial blood from the circle of willis to the internal jugular vein was created in ten monkeys. continued patency of the shunt was confirmed angiographically. cerebral blood flow measurements were then obtained with the shunt both open and occluded. flow was also determined in response to elevations of systemic arterial pressure and raised arterial carbon dioxide tensions (paco2), again with the shunt both patent and occluded. in addition, flow through th ... | 1978 | 98854 |
| [some aspects relating to the aflatoxin generation during the self-heating of cereals]. | in a stored batch of grain which was already affected by mould-formation tests were carried out with the known aflatoxin producer aspergillus flavus. a significantly lower aflatoxin production ensued if the mould growth was not connected with self-heating of the stored product. however, in conformity with increasing mould formation the germinating power was adversely affected and the significant signs (fatty acid number, reductive and none-reductive sugars) were influenced in the grain, irreleve ... | 1978 | 98933 |
| pars plana vitrectomy as a primary treatment for acute bacterial endophthalmitis. | we successfully treated six patients with culture-proven acute bacterial endophthalmitis by a combination of emergency pars plana vitrectomy and the instillation of intravitreal antibiotics. all six patients regained satisfactory vision. | 1978 | 99040 |
| interferon inducing activity of polyinosinic acid. | although poly(i) is generally considered to be inactive as an interferon inducer, we have found several authentic poly(i) preparations to be effective inducers. their interferon inducing ability varied considerably from one cell system to another. in human diploid fibroblasts, primed with interferon and superinduced by cycloheximide and actinomycin d, all active poly(i) samples proved nearly as effective in inducing interferon as poly(i).poly(c). in primary rabbit kidney cell cultures, the activ ... | 1978 | 99486 |
| lumbar spondylectomy in the subhuman primate. | removal of the 2nd or 3rd lumbar vertebrae (or both) has been accomplished in the subhuman primate (macaca mulatta). variations between this animal and the dog in posture, vertebral column anatomy, and spinal cord blood supply made no apparent difference in the results when compared with those in previous experiments. all macaques were able to clinb and to use their hind legs in a normal manner within 3 days after surgical operation. once hair had regrown over the surgical incision, persons not ... | 1978 | 100028 |

| dietary modification of amphetamine stereotyped behaviour: the action of tryptophan, methionine, and lysine. | rats fed diets high in tryptophan, methionine, and tryptophan plus methionine or lysine were subsequently injected with 10 mg/kg d-amphetamine. the amount of amphetamine-induced stereotyped behaviour observed varied as a function of the dietary addition, with methionine showing the greatest difference to controls, and lysine the least. whole brain catecholamine levels and 5-hydroxytryptamine levels also showed amino acid-specific changes. | 1979 | 108724 |
| evidence of a high-activity c type of carbonic anhydrase in human ciliary processes. | carbonic anhydrase activity was found in the ciliary process of fresh human donor eyes, originating from an enzyme antigenically similar to the erythrocyte high-activity isoenzyme hca c. it was sensitive to inhibition by acetazolamide and resistant to inhibition by halides like hca c. the enzyme is probably identical with hca c. its tissue concentration was one fifth to one tenth of that in the human kidney. the erythrocyte low-activity isoenzyme hca b was also found in the processes as a contam ... | 1979 | 110722 |
| lethal effect of protamine and histone on competent bacillus subtilis cells. inhibition of genetic transformation by protamine in sublethal concentration. | under experimental conditions of genetic transformation, protamine and total histone were bactericidal for bacillus subtilis cells. the abilities to cause lethality were very similar for both, either protamine or histone, with no antagonistic effects amongst these natural polycations. with both basic proteins acting simultaneously the enhancement was higher than a summation of the separate lethal effects. sublethal concentration of protamine added at the beginning of transformation time, produce ... | 1979 | 111002 |
