the adhesion of film coatings to tablet surfaces--the effect of some direct compression excipients and lubricants.the effect of some direct compression excipients and lubricants on the adhesion of hydroxypropyl methyl cellulose films has been examined using a specially designed tensile testing apparatus (fisher & rowe, 1976). the adhesion was found to be influenced by both the roughness, including microporosity, of the tablet surface and its polarity. tablets prepared from microcrystalline cellulose showed very high adhesions despite having relatively smooth surfaces, owing to the surface being saturated wi ...199822617
the measurement of the adhesion of film coatings to tablet surfaces: the effect of tablet porosity, surface roughness and film thickness.the effect of tablet porosity, surface roughness and film thickness on the adhesion of hydroxypropyl methyl cellulose films to placebo tablet substrates have been studied using a specially designed tensile tester (fisher & rowe, 4976). there were direct relations between measured adhesion and tablet porosity and also surface roughness and tablet porosity. the effect of film thickness on the measured adhesion is complex with an initial decrease with thicknesses up to 35 micron and then a gradual ...199926762
relative tissue distribution of radioactivity in rats with endocrine "autonomous" breast carcinomas after 3h-,99mtc-, and 64cu-bleomycin.the localization of 64cu-, 3h-, and 99mtc-labeled bleomycin was studied in tissues of fisher rats bearing an endocrine autonomous breast tumor. the 64cu-bleomycin showed a greater uptake than 3h- and 99mtc-bleomycin in the breast tumor at all time intervals studied, from 2 to 72 hr after the tracer. this same differential uptake was shared by the liver and kidney.197545938
cordycepin inhibition of 3-methylcholanthrene-induced transformation in vitro.cordycepin (3-deoxyadenosine), an inhibitor of poly (a) synthesis, was found to inhibit the induction of the endogenous type "c" rna virus by 5-iodo-2'-deoxyuridine in a line of fisher rat embryo cells (h43) grown in vitro, and when continuously incorporated into the medium at those same concentrations, it was found to protect the cells from transformation by the chemical carcinogen 3-methylcholanthrene.197554927

the evolution of dominance: haldane v fisher revisited.fisher's model for the evolution of dominance indicates that the accumulation of dominance modifiers will be accelerated by (1) an increased frequency of the mutant heterozygote, (2) increased selection for the phenotype of the normal homozygote. the model has been criticised by haldane on the grounds that point (1) is not fulfilled, that is dominance appears to be more common in populations with a low frequency of mutant heterozygotes (populations of inbreeders). in support of fisher's model it ...1985268310
error estimate for the diffusion approximation of the wright--fisher model.the wright--fisher model and its approximating diffusion model are compared in terms of the expected value of a smooth but arbitrary function of nth-generation gene frequency. in the absence of selection, this expectation is shown to differ in the two models by at most a linear combination (with coefficients depending only on the derivatives of the smooth function involved) of the maximum mutation rate and the reciprocal of the population size.1977270745

the influence of the mating system on the maintenance of genetic variability in polygenic characters.the traditional models of the effect of assortative mating and inbreeding on the genetic variance of polygenic characters (fisher 1918; wright 1921) presume that there is no natural selection or mutation. in a large population, the genetic variance determined by additive genes may then increase by up to a factor of two with local inbreeding, and even more with assortative mating. the classical models are still used to interpret data from natural populations. but contrary to their assumptions, mo ...1977407132

effects of carbon disulfide on motor function and responsiveness to d-amphetamine in rats.male, albino rats of the fisher strain were exposed to 2 mg carbon disulfide/l of air for 4 hours per day, 5 days per week for 6 weeks. neurobehavioral effects were not observed after 3 weeks of dosing, but hindlimb extensor responses and performance on the inclined screen (motor coordination) were impaired after 6 weeks of exposure. forelimb grip strength and exploratory locomotor activity were not affected. three weeks after cessation of dosing, recovery of function was observed. rats exposed ...1979551304
a method for the routine assessment of fore- and hindlimb grip strength of rats and mice.a technique to measure the fore-and hindlimb grip strength of rats (adult and preweanling) and mice is described. the procedure utilizes inexpensive equipment, is rapid and efficient, and provides continuous level data. as a means of validating the sensitivity of the test, the effects of phenobarbital and chlordiazepoxide on the grip strength of adult fisher strain and sprague-dawley derived adult rats were investigated. dose-related decreases in fore- and hindlimb grip scores were observed in b ...1979551317
the influence of diazepam administration in rats bearing the r3230ac mammary carcinoma.the growth of the r3230ac mammary carcinoma was studied in female fisher 344 rats that were treated with diazepam. diazepam at 250 micrograms/animal/day (2.5 mg/kg body weight) and 500 micrograms/day was administered for 4 weeks, starting 2 days before subcutaneous transplantation of uniform pieces of the tumour. tumour size was significantly increased in the group receiving 250 micrograms but was below the levels observed in the saline treated controls in those given 500 micrograms diazepam. pl ...1979552103
[4 cases of one and a half syndrome' observed following surgery of primary pontine hemmorhage].in 1967, fisher named the "one and a half syndrome" for a particular ocular movement which is observed in the lesion of pontine tegmentum, when horizontal movement of one eye is totally disabled and the abducence of another eye is only preserved associating mono-ocular nystagmus in the same eye. vertical movement and convergence are preserved. we experienced this syndrome in four cases of small localized hematoma of the pontine tegmentum which were all removed under operative microscope. all pat ...1977560193
age pigments, cell loss and hippocampal function.the specific aims of this study were to perform direct correlational analyses of age differences in learning, short-term memory and arousal in relation to cell loss and lipofuscin increase in the hippocampus ca1 zone and in visual area 17 of the fisher 344 rat. the following tentative conclusions can be made from the results presented in this study: (1) significant age differences in 2 and 6 hour passive-avoidance retention or memory between mature and old rats were related to non-significant ag ...1979571502
helminth parasites of fisher martes pennanti (erxleben) from manitoba, species of helminths were recovered during a survey of 162 fisher (martes pennanti) from four areas of manitoba: baylisascaris devosi in 52 fisher; taenia sibirica in 25; physaloptera sp. in nine; alaria mustelae in two; metorchis conjunctus in one; trichinella spiralis in one of 81; molineus sp. in one. b. devosi was the most prevalent parasite and differences in its geographical distribution were possibly related to population density of fisher. the prevalence of other parasites did not ...1979574167

fisher syndrome of ophthalmoplegia, ataxia and areflexia (a report of three cases with unusual features). 1977612667
syndrome of ophthalmoplegia, ataxia and areflexia.the clinical details and results of some laboratory investigations are described in 4 patients who initially presented with severe external ophthalmoplegia, ataxia and areflexia. in 3 of these patients paresis of the limbs was restricted and minimal as in the syndrome first described by fisher (1956). the fourth patient initially presented with similar symptoms but his illness progressed to a more typical form of acute idiopathic polyneuropathy, confirming fisher's (1956) contention that this sy ...1977616611
age differences in short-term memory and cell loss in the cortex of the rat.studies with human and animal subjects have indicated age declines in short-term memory and cell loss in the cortex. cell loss has been estamated by descriptive nonautomated methods. declines in short-term memory may be related to reduced learning, movtivation, motor capacity, or some combination of these factors. passive-avoidance tests of memory minimize these factors. direct correlational studies on learning and memory in relation to cell loss in the same subject are not feasible in man and t ...1978624457
[ophthalmophlegic polyneuritis. a clinical contribution to fisher's syndrome].this paper describes 6 patients with the syndrome of ophthalmoplegic polyneuritis fairly identical to that described by fisher. the most striking symptom of the ophthalmoplegic polyneuritis is the acute ophthalmoplegia, usually total and bilateral, often with sparing of the pupillary reflexes and of the levater palpebrae. the disturbances may simulate a paralysis of gaze or a internuclear palsy. following features may announce this illness: mild harmless infectious disease, sensory deficits, gen ...1978625400
rate of polymer formation and entropy production during competitive replication.the rate of increase in the mean polymer formation rate constant during competitive replication by qbeta rna variants (kramer et al., 1974) has been shown to agree statistically with the variance in their formation rate constants. this result demonstrates that fisher's fundamental theorem of natural selection (fisher, 1930) can define time variations in the mean rate of synthesis for a heterogeneous population of replicating polymers. it was also revealed that rna replication, far from equilibri ...1978633382
frequency and cooccurrence of vocal tract dysfunctions in the speech of a large sample of parkinson this study, the frequency of occurrence of speech and voice symptoms in 200 parkinson patients was defined by two expert listeners from high-fidelity tape recordings of conversational speech samples and readings of the sentence version of the fisher-logemann test of articulation competence. specific phonemes that were misarticulated were catalogued. other vocal-tract dysfunctions, including laryngeal disorders, rate disorders, and hypernasality, were also recorded. cooccurrence of symptoms in ...1978633872
tolerance to amphetamine's facilitation of self-stimulation responding: anatomical specificity.further work on the phenomenon reported by leith and barrett, wherein tolerance was shown to develop to the well-known d-amphetamine-induced facilitation of self-stimulation, clearly indicates that the development of such tolerance is dependent on the location of the stimulating electrode. thirty-seven fisher or harlan rats were trained to bar press for hypothalamic stimulation (60 hz, ac). following several sessions during which small doses of d-amphetamine were administered to demonstrate faci ...1978638781
survival of normal and magnesium-deficient erythrocytes in rats: effect of magnesium-deficient diet vs. splenectomy.magnesium deficiency in rats causes anemia, the mechanism of which is unknown. the effect of dietary magnesium, splenectomy, and magnesium content of erythrocytes on erythrocyte survival was studied in fisher rats. half of the animals were splenectomized, the remainder sham-splenectomized; each group was subdivided, and some were placed on a magnesium-deficient diet, the rest on a control diet. after 6 weeks, each of the four subgroups was divided, half were given 51cr-labeled red cells from mag ...1978641390
hybridization between different strains of schistosoma intercalatum fisher, 1934 from cameroun and zaïre.the offspring from hybridization experiments between schistosoma intercalatum, cameroun (intermediate host bulinus forskalii) and s. intercalatum, zaïre (intermediate host b. globosus) was investigated. reciprocal crosses between the two forms were performed. f1- and f2-miracidia developed in both parental intermediate hosts. the minimum prepatent period was 24 days at 26 degrees c, an average of the prepatent periods for the two parental strains. the total cercariae production per 100 exposed s ...1978659822
the effect of halothane anaesthesia on liver regeneration.the effects of halothane and diethyl ether on the regenerating liver following 70 per cent hepatectomy were studied in fisher/344 (f) rats. our aim was to discover whether halothane administered repeatedly and over prolonged periods could influence the liver regenerative process or hepatocyte function. we also wished to know if the effects of halothane differed from those of diethyl ether. we found: 1. prolonged halothane or diethyl ether anaesthesia did not inhibit liver mitotic activity, even ...1978667672

selfish genes, evolutionary games, and the adaptiveness of behaviour.the science of sociobiology, which began in principle with the work of fisher and haldane and has more recently been developed by hamilton, maynard smith, trivers, wilson and others, has been the centre of both scientific and political controversy. dr parker discusses the strengths and weaknesses of the approach, and illustrates that behaviour can be adapted in a complex way in conformity with sociobiological theory.1978683325
[change in the concentration and non-homogeneity of rna and sh-group distribution in pyramidal neurons of cat cerebral cortex following epileptiform activity].concentrations of rna and sh-groups were determined in pyramidal neurons of somatosensory cortex of the intact cats and after epileptiform activity induced by electrical stimulation. the mean concentrations of rna and of sh-groups and the fisher information exponent were calculated in different zones of the pyramidal neuron cytoplasm zone of the apical dendrite and that of the axon departure. with epileptiform activity, rna and sh-group contents and the information exponent were seen decreased. ...1978695011
on factors possibly restricting the distribution of schistosoma intercalatum fisher, 1934.two hypotheses have been postulated explaining the limited distribution of schistosoma intercalatum. the first hypothesis is correlated with physical factors and behaviour of cercariae. histochemical and ultrastructural studies have shown that in response to increased temperature change the cercariae of s. intercalatum form aggregates, unlike other schistosome cercariae of man, which are non-infective to the definitive host. the aggregates are formed by the release of the adhesive post-acetabula ...1978695826
[effect of microbial and tumor cell adaptation to rubomycin on their uptake of rubomycin and carminomycin].anthracycline antibiotics rubomycin (daunomycin) and carminomycin rapidly accumulated in the bacterial and ascitic tumor cells and their intracellular concentrations significantly exceeded the concentrations in the medium. the strains of staph. aureus and fisher mouse ascitic lymphadenosis l-5178/p resistant to rubomycin preserved sensitivity to carminomycin. the resistance of the bacterial and tumor strains to rubomycin was accompanied by a significant decrease in the accumulation of rubomycin ...1978697342
[effect of normal microflora, age and sex of rats on serum igg2 levels].germfree and conventional rats of fisher inbred strain and mongrel animals were used in this study. igg2 was separated from the pool serum of mongrel rats, and anti-igg2 was obtained by hyperimmunization of rabbits. igg2 content was determined by in the sera of different groups of rats radial immunodiffusion. there was 5.4 times less igg2 in the sera of fisher germfree rats than in conventional fisher animals; its level in female animals was by 10--15% higher than in the male ones. the first hou ...1978698380
