| effects of rapid cooling on mechanical and electrical responses in ventricular muscle of guinea-pig. | the effect of rapidly lowering bathing solution temperature from 36.5 +/- 0.5 degrees c to various low temperatures was examined in guinea-pig ventricular muscle to explore the possible role of intracellular ca2+ store sites in excitation-contraction coupling. rapid cooling from 36.5 +/- 0.5 degrees c to below 18 degrees c caused contracture (rapid cooling contracture, r.c.c.) with subthreshold depolarization for contraction, if electrical stimulation was applied before cooling. r.c.c. peak tens ... | 1985 | 3989731 |
| size, form and orientation of the neuronal perikarya and nuclei in the nucleus infundibularis of the male rat. | size, form and orientation of nerve cells of the nucleus infundibularis have been analyzed in frontal, horizontal and sagittal semithin sections of vestopal-embedded hypothalami of the male rat. morphometric studies were performed with a semiautomatic image analyzing system. by combining data from three different planes of section the three-dimensional size, shape and orientation of perikarya and nuclei in the different parts of the nucleus infundibularis as well as gradients in mediolateral, ro ... | 1985 | 3989281 |
| can the rapid semiquantitative estimation of serum c reactive protein be adapted for the management of bacterial infection? | serum c reactive protein concentrations measured by a laboratory based assay were compared with the semiquantitative results obtained with a visual agglutination method (well-cotest, crp kit). using this agglutination kit, diluting serum 1/10 and 1/20 gave c reactive protein results which could be of more clinical value than those obtained using the 1/2, 1/4, 1/8, and 1/16 dilutions recommended by the manufacturers. the kit was also used on the ward by junior medical staff, who showed that after ... | 2014 | 3988960 |
| carbohydrate metabolism in transforming lymphocytes from the aged. | there is an age-related decline in immune capacity which has been linked to a decreased response of lymphocytes to mitogens in vitro. during transformation, lymphocytes require a marked increase in energy production and biosynthesis which is supplied primarily by glycolysis. in the elderly, the glycolytic enzymes increase significantly in transforming lymphocytes at least 24 hr later than in the young and then at significantly reduced levels. glucose utilization is also impaired in stimulated ly ... | 2014 | 3988814 |
| clinicians' knowledge about the families of their patients. | this study was designed to determine what doctors and nurses in family medicine actually know about the families of their patients; to assess the accuracy of the professed knowledge; and to relate this knowledge to the patient's level of satisfaction and compliance. clinicians completed questionnaires dealing with their knowledge of personal and family information about patients. these patients completed a mirror-image questionnaire--to assess the accuracy of the clinician's responses--and a que ... | 2014 | 3988012 |
| complement and hla. further definition of high-risk haplotypes in insulin-dependent diabetes. | the families of 41 probands with type i (insulin-dependent) diabetes mellitus (iddm) were typed for hla-a, hla-b, and hla-dr antigens in addition to the complement polymorphisms c2, c4a, c4b, and bf. all of these loci are encoded on the short arm of human chromosome 6 in a narrow region. alleles at hla-b (8, 15, 18, and 40), hla-dr (3 and 4), and bf (f1) have been associated with increased relative risk (rr) for iddm, while hla-b7 and hla-dr2 have been associated with decreased rr for iddm. this ... | 1985 | 3987976 |
| purification of the 25-kda vibrio cholerae major outer-membrane protein and the molecular cloning of its gene: ompv. | the 25-kda peptidoglycan-associated outer-membrane protein and most likely porin of vibrio cholerae is a major immunogenic species. it has been purified by ion-exchange elution on hydroxyapatite followed by gel filtration on bio-gel p150 both in the presence of sodium dodecyl sulfate. this protein, of greater than 90% purity as judged by western blotting, has been used to raise antibodies in rabbits. the antisera were then used to screen v. cholerae gene banks, constructed in escherichia coli k1 ... | 1985 | 3987695 |
| cone photoreceptor shedding in the tree shrew (tupaia belangerii). | tree shrews were sacrificed at various times during a 12 h light-12 h dark cycle and the retinal pigment epithelium (rpe) was examined for phagosomes. analysis of photoreceptor densities showed that the tree-shrew retina consists of approximately 96% cone photoreceptors. therefore, phagosomes in the rpe were assumed to be mostly those of cones. a peak in the number of rpe phagosomes was found about one hour after the onset of light. the number of phagosomes/mm rpe during the light cycle varied f ... | 2014 | 3986885 |
| effects of peripheral vasoconstriction on the measurement of blood pressure in a finger. | using noninvasive techniques only, the fall in mean pressure and the pulse amplification between brachial and finger arterial pressure were measured in six anaesthetised female subjects during surgery. brachial pressure was measured every 2 min with an oscillometric technique. finger pressure was measured continuously using an arterial volume clamp method. in addition changes in the degree of peripheral vasoconstriction were established on an adjacent finger with a photo reflection plethysmograp ... | 2014 | 3986857 |
| a study of the extent and pathology of experimental avulsion injury in rabbit arteries and veins. | a comparison was made between operating microscope observations and histopathological examination of the ruptured ends of experimentally avulsed rabbit femoral arteries and veins. under the operating microscope no damage was evident in arteries or veins more than 0.8 cm (on average) from the rupture site, the common lesions being tears, holes, bruising, sleeving and dilatations. in light microscope and electron microscope studies arterial and venous lesions were often noted up to 4 cm from the r ... | 1985 | 3986426 |
| molecular mechanisms of olfactory reception. vi. kinetic characteristics of camphor interaction with binding sites of rat olfactory epithelium. | camphor binding to a possible receptor of rat olfactory epithelium has been studied within the ligand concentration range 10(-11)-10(-6) m. at these concentrations camphor is bound by a set of receptors. they are distinguished by both the affinity to the ligand (k1 = 5 x 10(-10) m, k2 = 3.5 x 10(-8) m, k3 approximately equal to 10(-6) m) and their amount in the epithelium. the differences in the affinities are due to different values of the association rate constant of camphor (k1), which varies ... | 1985 | 3986222 |
| exclusive activation of aromatic amines in the marine mussel mytilus edulis by fad-containing monooxygenase. | microsomes from the marine mussel mytilus edulis possess the enzyme activity that selectively metabolizes primary aromatic amines and not polycyclic aromatic hydrocarbons. this activity is nadph-dependent and has a ph optimum at 8.4. by these characteristics this enzyme is identical with the purified pig liver fad-containing monooxygenase (ec 1.14.13.8, dimethylaniline monooxygenase). the exposure of mussels to diesel-2 oil does not induce the enzyme activity. these results are discussed in term ... | 1985 | 3985956 |
| [reciprocal regulation of growth and differentiation in hepatocytes by cell surface modulator and loss of regulation during carcinogenesis]. | in primary monolayer cultures of mature rat hepatocytes, cell growth and hepatocyte-specific functions were mediated by a cell surface component (named the cell surface modulator) via cell-cell contact. the modulator activity was heat-labile and trypsin-sensitive. activity was also found in plasma membranes from kidney, brain, lung, and erythrocytes. the modulator was solubilized by 4% octylglucoside plus 4m guanidine hcl from liver membranes. the molecular weight of the modulator was 670kd dete ... | 1985 | 3985639 |
| apple juice. an unappreciated cause of chronic diarrhea. | chronic nonspecific diarrhea (cnsd) remains a common pediatric problem. previous reports have suggested disordered small intestinal motility, food intolerances, dietary fat restriction, and excessive fluid consumption as possible contributory factors. we have recently encountered a subset of children with cnsd in whom nonexcessive apple juice intake seemed to cause their diarrhea. in five subjects, ingestion of 240 ml of apple juice disclosed evidence of significant carbohydrate malabsorption by ... | 2014 | 3984976 |
| ventricular shunt survival in children with neural tube defects. | ventricular shunting has dramatically improved the care of children with hydrocephalus. yet shunt malfunctions are extremely common and cause significant morbidity. to document shunt problems in children with a neural tube defect and hydrocephalus, 67 children born since 1973 were studied via life-table analysis. 28% of the shunts failed within the first 6 months after insertion, 37% failed within the first year and 50% failed by 4 1/2 years after insertion. shunt survival was similar in childre ... | 2014 | 3984790 |
| [determination of free serum phenol by gas-liquid chromatography in hemosorption]. | a modified procedure is developed for estimation of free phenol in blood serum by means of gas-liquid chromatography, appropriate in clinico-biochemical assays. the method enabled to evacuate the blood serum free phenol in healthy persons as well as in various pathologies of abdominal cavity before and after hemosorption. after hemosorption a distinct decrease of the free phenol content was observed in blood, correlating with improved clinico-biochemical patterns of the patients, with a decrease ... | 2014 | 3984277 |
| differentiation of volume averaging and mass on magnetic resonance images of the mediastinum. | volume averaging of high intensity mediastinal fat and low intensity flowing blood in mediastinal vessels can mimic a mediastinal mass on magnetic resonance (mr) images of the chest. however, when different repetition times (tr) are used to perform two imaging sequences, volume averaging can be distinguished from true disease, since the ratio of intensities of mediastinal fat, which is volume averaged, to nonvolume-averaged fat will remain relatively constant on a pair of images obtained using d ... | 2014 | 3983392 |

| management of chronic pain. | pain is an unpleasant, subjective experience which escapes objective measurements. it is the normal response to the disruption of healthy tissues, but its persistence beyond the period of healing should alert the practitioner to other unrecognized causes. on the other hand, learned pain is a condition resulting mainly from socio-emotional factors in the absence of progressive, invasive and, most of the time, demonstrable pathology. the key to success in the management of a painful condition is a ... | 2014 | 3969229 |
| further studies on the role of neuraminidase and the mechanism of low ph dependence in influenza virus-induced membrane fusion. | the role of neuraminidase and the mechanism of low ph dependence in influenza virus-induced membrane fusion have been studied further using fowl plague virus (fpv, h7n1). two specific anti-fpv neuraminidase antisera obtained from chickens immunized with recombinant virus strains inhibited viral neuraminidase activity without influencing its haemagglutinating activity. these sera totally inhibited the fpv-induced fusion of erythrocytes and partially reduced haemolysis. but both fusion and haemoly ... | 1985 | 3968541 |
| seroepidemiological studies of el tor cholera in bangladesh: association of serum antibody levels with protection. | in rural bangladesh, family contacts of patients with cholera were studied prospectively to examine whether protection against colonization and disease due to vibrio cholerae o1 was associated with circulating antibodies to v. cholerae. family contacts (1,071) of 370 patients with cholera were visited daily for 10 days, cultured for v. cholerae, and queried about diarrhea. sera collected on days 1 and 21 were assayed for vibriocidal antibodies, igg and iga antibodies to cholera toxin, and igg an ... | 1985 | 3968450 |

| occurrence of 2-keto-deoxyoctonic acid 5-phosphate in lipopolysaccharides of vibrio cholerae ogawa and inaba. | a phosphorylated 2-keto-3-deoxyoctonic acid (kdo) was released from the lipopolysaccharides of vibrio cholerae ogawa and inaba after strong acid hydrolysis. the phosphorylated kdo was identified by gas-liquid chromatography and mass spectrometry after reduction and permethylation as kdo-5-phosphate and an isomer of it being phosphorylated at position 7 or 8. after treatment with alkaline phosphatase, kdo was detected by gas-liquid chromatography and mass spectrometry. it was indistinguishable fr ... | 1985 | 3968044 |
| intestinal absorption of bacterial antigens in normal adult mice. ii. a comparative study of techniques. | marked differences were seen in the oral absorption of boivin antigen (ba) and flagellin (fla) using antigens labelled by 3h-dinitrophenylation. thus, after feeding 3h-dnp-fla, a large proportion of the label was rapidly absorbed, concentrated and degraded by the liver so that no antigenic material could be recovered from the circulation. in contrast, the absorption of 3h-dnp-ba was low and slow; the absorbed material appeared stable and not readily taken up by the liver, so that 8-20% of the no ... | 1985 | 3967930 |
| intestinal absorption of bacterial antigens in normal adult mice. i. preparation and characterization of the antigens. | the preparation of flagellin (fla) from salmonella adelaide and boivin antigen (ba) from vibrio cholerae is described. these two antigens differed chemically from each other and showed marked differences in their degradability by mouse intestinal juice in vitro and in their fate in the intact mouse when given intravenously. unlike ba, fla was rapidly degraded in intestinal juice and readily sequestered and degraded by the liver. the suitability of these antigens in oral absorption studies is dis ... | 1985 | 3967929 |
| iron-vibriobactin transport system is not required for virulence of vibrio cholerae. | the possible requirement of a functional siderophore (vibriobactin)-mediated iron transport system in the pathogenicity of vibrio cholerae was determined. two mutants of v. cholerae defective in the iron-vibriobactin transport system were examined for their ability to multiply and elicit diarrhea in infant mice. one mutant, 40130, was unable to synthesize vibriobactin. the second mutant, 1510, was able to synthesize, but not transport, the siderophore. both mutants retained the ability to multip ... | 1985 | 3967921 |

| pyostomatitis vegetans. a reactive mucosal marker for inflammatory disease of the gut. | pyostomatitis vegetans is a rarely occurring disorder of the oral mucosa, which has a dramatic clinical picture and a striking histopathologic pattern. moreover, the condition is a highly specific oral mucosal marker for inflammatory bowel disease, particularly ulcerative colitis. our findings in two cases and a review of the literature emphasize the relationship of pyostomatitis vegetans to inflammatory bowel disease and the vegetating dermatoses. | 2014 | 3966824 |
| flammable surgical drapes--a patient and personnel hazard. | after a surgical drape fire, the new york state society of anesthesiologists, operating room safety committee, investigated the factors contributing to it. subsequently, eight detailed cases were collected. it found that no voluntary standards or government regulations exist to oversee the flammability of surgical drapes; no agency or bureau collects reports of operating room fires; most professionals are not aware of the hazard because no labelling requirements regarding flammability exist and ... | 2013 | 3966652 |

| direct synthesis of low-density lipoprotein apoprotein b in the miniature pig. | the metabolism of apoprotein b (apo b) was investigated in five miniature pigs following the injection of radiolabeled, very low-density lipoproteins (vldl). the fractional catabolic rate (fcr) for vldl apoprotein b was 0.71 +/- 0.10 h-1 (mean +/- se), the rate of flux was 0.77 +/- 0.05 mg h-1 kg-1, and the pool size of apoprotein b averaged 1.26 +/- 0.20 mg kg-1. examination of precursor-product relationships between vldl and low-density lipoprotein (ldl) apoprotein b illustrated that a signifi ... | 1985 | 3965861 |
| effects of aging and illness on the pituitary testicular axis in men: qualitative as well as quantitative changes in luteinizing hormone. | decreased testicular function occurs as a concomitant of aging in men and is accentuated by the presence of systemic illness. previous studies identified an intrinsic leydig cell defect, as reflected by high lh to testosterone ratios and impaired hcg responsiveness in older men. this study questioned whether a qualitative change in lh secretion, as reflected by secretion of lh with an altered ratio of biological to immunological lh (b/i) activity, might occur during aging. to examine this possib ... | 1985 | 3965490 |
