| syndactyly and split hand. supplement. | in a series of studies of clinical and radiological features of hand anomalies, the author has recently encountered cases which may be explained by reference to the relationship between syndactyly and split hand. these cases suggested how the typical split hand is formed prenatally, and it is concluded that the typical split hand should not be classed as "arrest of development of parts" due to embryonal failures. | 1990 | 213354 |
| mapping the atp-binding site in the catalytic subunit of adenosine-3':5'-monophosphate-dependent protein kinase. spatial relationship with the atp site of the undissociated enzyme. | a set of 24 atp analogs modified at various positions of the atp molecule was used for mapping the atp-binding site in the free catalytic subunit (c) of camp-dependent protein kinase (type i). ki values for these analogs (of which 23 were shown to be competitive with atp) were measured and compared with ki values previously obtained for the same set of analogs upon binding to the undissociated form of the enzyme (r2c2). it was found that modifications at the adenine part of atp bring about a con ... | 1990 | 213278 |
| immunological studies on cytochrome c oxidase: arrangements of protein subunits in the solubilized and membrane-bound enzyme. | seven protein subunits of cytochrome c oxidase from bovine heart were isolated by gel filtration in the presence of sodium dodecyl sulphate (subunits i, ii and iii) and guanidine hydrochloride (subunits v, vi and vii), and ion-exchange chromatography in 6 m urea (subunit iv) after the enzyme had been dissociated in 6 m guanidine hydrochloride. when analysed by highly cross-linked sodium dodecyl sulphate/polyacrylamide gel electrophoresis in the presence of urea, the apparent molecular weights we ... | 1978 | 213267 |
| a time-resolved electron spin resonance study of the oxidation of ascorbic acid by hydroxyl radical. | time-resolved electron spin resonance (esr) spectroscopy for the study of radicals produced by pulse radiolysis is illustrated by a study of the oxidation of ascorbic acid by oh radical in aqueous solution. in basic solution, the direct oxidation product, the ascorbate mono-anion radical, is formed within less than 2 mus of the radiolysis pulse. in acid solutions (ph 3(-4.5), n(2)o:saturated) three radicals are initially formed, the ascorbate mono-anion radical, an oh adduct seen also in steady- ... | 1990 | 213133 |

| the spin-state transition of the hemochrome non-equilibrium conformation in partially reduced human methemoglobin. a pulse-radiolysis study of aqueous-methanol solutions of methemoglobin. | the effect of external parameters on the relaxation process of the hemochrome-type non-equilibrium conformation in partially reduced methemoglobin has been investigated. the relaxation of the intermediate ferrous low-spin state to the high-spin equilibrium conformation of hemoglobin appears to be facilitated particularly by protons and phosphate ions. in addition to studying the spin-state transition in aquomethemoglobin we have also studied it in complexes of the heme group in methemoglobin wit ... | 1978 | 211030 |
| localization of central noradrenergic mechanisms in cardiovascular regulation in rats. | 1. various drugs were injected stereotactically into the brain of anaesthetized rats. 2. noradrenaline injected into the area of the nucleus of the tractus solitarius in the lower brain stem or into the far anterior hypothalamus/pre-optic region induced a fall in blood pressure and heart rate related to the administered dose. 3. when injected into the anterior hypothalamus/pre-optic region, clonidine and alpha-methylnoradrenaline induced a long-lasting decrease in blood pressure and heart rate. | 1975 | 210991 |
| electron-paramagnetic-resonance studies on nitrogenase of klebsiella pneumoniae. evidence for acetylene- and ethylene-nitrogenase transient complexes. | klebsiella pneumoniae nitrogenase exhibited four new electron-paramagnetic-resonance signals during turnover at 10 degrees c, ph7.4, which were assigned to intermediates present in low concentrations in the steady state. 57fe-substituted mo--fe protein showed that they arose from fe--s clusters in the mo--fe protein of nitrogenase. the new signals are designated: ic, g values at 4.67, 3.37 and approx. 2.0; vi, g values at 2.125, 2.000 and 2.000; vii, g values at 5.7 and 5.4; viii, g values at 2. ... | 1978 | 210766 |
| [interferonogenic and antiviral activity of the double-stranded replicative form of phage f2 rna in tissue culture and on animals]. | biological activity of a new natural interferon inductor, the replicative rna form of phage f2 (rff2) was studied. a possibility of using rff2 for production of highly active interferon under conditions of superinduction providing an increase in the interferon yield by to 256--512 times as compared to the control samples was shown. the protective interferonogenic and antiviral effect of rff2 in mice infected with semliki forest virus (sfv) and tickborne encephalitis virus (tbev) was studied on a ... | 1978 | 210710 |
| glucagon effects on plasma cyclic amp and other reactants in normals and low insulin responders. | the metabolic response to i.v. glucagon was evaluated in 11 normal individuals and 8 healthy low insulin responders. elevations of plasma cyclic amp and blood glucose were similar in both groups. accordingly, no indications were seen of differing hepatic responsiveness to glucagon. in contrast, the groups differed in the course of plasma glycerol during the test. | 1988 | 210635 |

| sonography of the common bile duct: value of the right anterior oblique view. | the common hepatic and proximal common bile ducts (common duct) lie anteriorly and generally to the right of the portal vein in the porta hepatis. this constant anatomic relationship can be used to demonstrate the common duct and to differentiate it from the portal vein by gray scale ultrasonography. the patient is scanned longitudinally from the right anterior abdominal wall with the ultrasound beam directed posteromedially until two tubular structures are demonstrated in the porta hepatis. the ... | 1994 | 205124 |
| the synthesis and secretion of serum albumin in morris hepatomas 5123tc and 9121. | in vivo, morris hepatomas 5123tc and 9121 do not secrete serum proteins into the bloodstream. however, they synthesize albumin, at a reduced rate, if compared with liver. the produced albumin accumulates, leading to an enlargement of the golgi apparatus and the appearance of intracellular vesicles. the proportion and the absolute amount of albumin found within the hepatoma cells is increased compared with liver. as described recently for liver in vivo and for hepatocyte suspensions, albumin is s ... | 1977 | 205109 |

| cyclic gmp regulation and responses of polysphondylium violaceum to chemoattractants. | in cells of the cellular slime mold polysphondylium violaceum an attractant, which is released during the aggregation stage, causes a transient rise of the cyclic gmp concentration. cells of this organism develop in shaken suspensions after they have finished growth. cell development is not accompanied by an increase in the edta stability of cell adhesion. both the developmental regulation and the specificity of chemotactic responses is reflected in the light scattering patterns recorded in cell ... | 1988 | 204422 |
