| psoas abscess complicating crohn's disease. | psoas abscess classically was described as secondary to tubercular spondylitis but now more frequently is a complication of an intraabdominal process such as crohn's disease. less well recognized is that the fever, flexion contracture of the hip, and weight loss characterizing psoas abscess may be the first indications of crohn's disease; in fact, gastrointestinal symptoms may be completely absent. psoas abscess was the first sign of crohn's disease in 11 of 46 reported patients. we present thre ... | 2010 | 2933953 |
| [formation of drug resistance in vibrio cholerae of non-o1 group inhabitating surface-water reservoirs]. | in the study of 255 v. cholerae strains unrelated to vibrio o group i (nag vibrios), which were isolated from water bodies in the region of the volga delta in 1977-1982, antibioticograms of 17 types were obtained and r factor was detected in 37.7% of the strains under study. the pronounced heterogeneity of nag vibrio populations, evaluated in minimal inhibitory concentration (mic) values with respect to different antibiotics, is specifically manifested by the presence of various dominating subpo ... | 1985 | 2933906 |
| [the so-called anterior tibio-peroneal trunk. its influence on the mode of revascularization by femoropopliteal bypass]. | femoro-popliteal bypass is difficult to perform when the posterior tibial artery originates at a high level in the lower limb. the problems arising from this anatomical variation, in which the tibio-peroneal trunk is, at least classically, anterior to the popliteal muscle, can be overcome by the technique described. | 2010 | 2933680 |
| localization of the e1b proteins of adenovirus 5 in transformed cells, as revealed by interaction with monoclonal antibodies. | monoclonal antibodies, one against the adenovirus type 5 e1b 55-kda protein and one against the e1b 21-kda protein, have been isolated and shown to recognize the same proteins as antitumor sera. immunofluorescence studies with these monoclonal antibodies on transformed cells containing the complete adenovirus early region 1, showed that the e1b 21-kda protein is localized in the perinuclear region. the e1b 55-kda protein is localized in a number of different sites: a strong fluorescence is obser ... | 1985 | 2932843 |

| sequence analysis of hla class ii domains: characterization of the dqw3 family of dqb genes. | hla class ii allelic variants within the dqw3-related family of genes carry distinct allo-specificities and have been implicated in specific hla-disease associations, such as insulin-dependent diabetes mellitus. to investigate the nucleotide variations which characterize dqw3 genes, we applied a novel cdna cloning strategy that uses a single-stranded vector/primer system to facilitate dna sequencing of allelically variable gene families. using a dqb-specific primer sequence and m13 bacteriophage ... | 2010 | 2925231 |
| [plasmapheresis in the combination therapy of patients with pyogenic destructive diseases of the lungs and pleura]. | plasmapheresis is an effective method for controlling the resorption factor in patients with pyogenic destructive diseases of the lungs and pleura. it facilitates rapid normalization of the parameters of the patients' clinical condition and the radiological picture, and reduces endogenous intoxication. protein-volemic disorders are more manifest in patients with a fatal outcome, which increase with the gradual progression of the disease and must be corrected before performing plasmapheresis. | 2009 | 2925111 |
| putative role of adenohypophysis in the osmoregulation of tilapia larvae (oreochromis mossambicus; teleostei): an ultrastructure study. | ultrastructure of the secretory cells in the adenohypophysis of tilapia (oreochromis mossambicus) larvae hatched in fresh water or sea water was compared. adenohypophysis of newly hatched larvae of tilapia is a short columnar body attached to the ventral floor of the diencephalon. the adenohypophysis is at its early differentiation stage, i.e., various types of secretory cells are still undistinguishable. only part of the cells in the putative rostral pars distalis look like typical endocrine ce ... | 2010 | 2925074 |

| the two-period crossover design in medical research. | the crossover design has enjoyed popularity with many clinical researchers, but has been criticized by biostatisticians. the central problem is the inability to derive an unbiased estimate of the treatment effect when differences occur because of the different sequences in which treatments are applied. this problem can be traced to a deficiency of the logic of the crossover arrangement itself. factors that can invalidate the findings of a crossover trial include nonuniform pharmacologic and psyc ... | 2009 | 2923388 |
| bilateral central retinal artery occlusions, disk drusen, and migraine. | a central retinal artery occlusion occurred in the left eye of a 25-year-old woman with migraine and bilateral intrapapillary drusen. an extensive investigation failed to establish the presence of any systemic disease or vasculopathy. eight years later she had a central retinal artery occlusion in her right eye. optic disk drusen and migraine may have combined to produce this patient's bilateral visual loss consequent to retinal vaso-occlusion. | 2010 | 2923150 |
| hyperuricemia, gout, and autosomal dominant polycystic kidney disease. | the relationship between hyperuricemia, gout, and autosomal dominant polycystic kidney disease (adpkd) is not widely recognized. in an attempt to further clarify this relationship, the authors have studied 17 patients with adpkd, 9 controls, 9 patients with proven gout and chronic renal failure, 11 patients with gout and normal renal function, and 11 patients with chronic renal failure. the mean serum uric acid concentration was higher in patients with adpkd as a group than in controls (8.0 +/- ... | 2010 | 2923134 |
| hepatic structural correlates of liver fibrosis: a morphometric analysis. | liver fibrosis is an important feature of many liver diseases, and the assessment of fibrosis is essential for diagnosis and prognosis. liver needle biopsy, however, tends to sample preferentially the soft parenchyma, which poorly reflects the true extent of fibrosis. therefore, we have searched for capsule and parenchymal features that are correlated with the fibrosis. to test for these correlations, we used a morphometric analysis of a rat model of liver fibrosis. we demonstrated that, of the ... | 1989 | 2920817 |
| maternal zinc during oral iron supplementation in pregnancy: a preliminary study. | 1. to investigate the possible effect of iron ingestion on maternal zinc status, one group of women was given 94 mg of iron per day as ferrous sulphate with multivitamins during the second and third trimesters of their pregnancies and another, control, group was given a placebo of multivitamins without iron. 2. the subjects given iron developed significantly lower plasma zinc concentrations than those in the control group. this effect on zinc was maximal by 6 weeks, whilst that on maternal iron ... | 2010 | 2920535 |
| paradoxical effect of respiration on ventricular rate in atrial fibrillation. | 1. in 50 subjects with atrial fibrillation we have attempted to demonstrate variation of ventricular rate with respiration, as evidence of cardioregulatory reflex activity. 2. the electrocardiogram was recorded for 3 min during spontaneous respiration. the presence of respiratory variation of r-r intervals was analysed by multiple regression against a cosine function (cosinor analysis), making it possible to determine the phase of respiration when the intervals were longest. 3. variation in vent ... | 2010 | 2920528 |
| late regrowth of pituitary adenomas after irradiation and/or surgery. hazard function analysis. | a retrospective analysis was performed on all patients with pituitary adenomas treated at the radiation oncology center, mallinckrodt institute of radiology, st. louis, missouri. of 210 patients treated from april 1954 through december 1982, 70 were treated with radiotherapy alone (rt), 121 received immediate postoperative rt (2 to 6 weeks), and 19 received rt following surgical failure. the mean follow-up time from the date of diagnosis for those patients alive at the time of last follow-up was ... | 2010 | 2920360 |
| congenital complete heart block in an infant with free plasma carnitine deficiency. | a newborn male presenting with congenital complete heart block was found to have low levels of free plasma carnitine. among the many complications of carnitine deficiency is a structural disruption of myocardial tissue. a deficiency of carnitine may be causally related to the presence of cardiac dysrhythmias in this patient on the basis of mechanical disturbance to the cardiac conducting system. | 2010 | 2920306 |
| the duty to warn about transfusion risks. | blood banks and transfusion services should anticipate that patients contracting transfusion-transmitted diseases will claim that these facilities have a duty to warn or notify patients of potential transfusion risks. although physicians treating patients must secure informed consent by describing significant risks and possible alternatives, precedent does not support extending informed consent requirements to the hospital or blood bank. nonetheless, efforts to find new sources of compensation m ... | 2010 | 2919960 |

| [treatment methods of keloid and hypertrophic scar formation]. | hypertrophic scar and keloid are diagnoses based on clinical symptoms. hypertrophic scar is an unacceptably enlarged scar, within the boundaries of the original wound; whereas keloid is an unacceptably enlarged scar infiltrating the surrounding tissue. hypertrophic scar and keloid belong to the same category of diseases, characterized by increased collagen development. the treatments employed are compression, excision, corticosteroid injections and irradiation. new medical treatments affecting t ... | 2010 | 2916252 |
| the biochemical and pathological changes produced by the intratracheal instillation of certain components of zinc-hexachloroethane smoke. | zinc chloride which is formed by igniting a mixture of zinc oxide and hexachloroethane in the production of white smokes has been shown to produce oedema when given to rats as a single instillation. the oedematous reaction, as assessed by histopathology and measurements of alveolar surface protein in lavage fluid, is variable, dose-dependent, and maximal at 3 days but at sub-lethal doses it regresses after 7 days. the parent compound, zinc oxide, does not produce these effects. in some animals t ... | 1989 | 2916244 |
| uptake of 63ni2+ in the central and peripheral nervous system of mice after oral administration: effects of treatments with halogenated 8-hydroxyquinolines. | oral administration of 63ni2+ to mice resulted in higher levels of the metal in the sciatic nerves, the trigeminal ganglia, spinal nerve roots and the spinal cord than in the cerebellum and the frontal cortex. in the sciatic nerves, the trigeminal ganglia and the spinal nerve roots a high vascular permeability may explain the preferential uptake of the 63ni2+. the higher accumulation of the 63ni2+ in the spinal cord than in the examined structures of the brain may be related to a diffusion from ... | 2010 | 2916242 |
| [stress fracture of the femoral neck in a marathon runner. case report and review of the literature]. | stress fracture of the femoral neck is rare, and the conditions in which it occurs are complex. an unusually high, rhythmically acting force resulting from body weight and muscle tension leads to decompensation of the dynamic equilibrium otherwise prevalent in bone metabolism in conditions of adaptation. even small differences in leg length predispose to fracture of the longer leg, owing to the increased muscular activity. bone scanning is helpful in diagnosis when no signs of fracture are revea ... | 2010 | 2916132 |

| assessment of right ventricular function in acute inferior myocardial infarction using 133-xenon imaging. | the detection of right ventricular dysfunction in acute inferior myocardial infarction is important because of its potentially serious consequences which may be remediable with the appropriate therapeutic manoeuvres. a technique has been developed to assess right ventricular function using 133-xenon. this technique was applied to 26 patients who had sustained an acute inferior myocardial infarction. right ventricular ejection fractions ranged from 7-54%, mean 30 +/- 11%, which was significantly ... | 2010 | 2914743 |
| one of two subunits of masking protein in latent tgf-beta is a part of pro-tgf-beta. | a high molecular mass latent form of transforming growth factor type-beta (tgf-beta) was purified to homogeneity from rat platelets by a seven-step procedure involving group-specific affinity chromatographies on red-toyopearl and zinc chelating-sepharose. the purified latent tgf-beta was a complex of tgf-beta (25 kda) and the binding protein previously named masking protein (approximately 400 kda) [(1986) biochem. biophys. res. commun. 141, 176-184]. analysis of the peptide structure by gel elec ... | 1989 | 2914605 |
| improved sexual function in hemodialysis patients on recombinant erythropoietin: a possible role for prolactin. | as it was reported that correction of anemia in long-term hemodialysis patients by recombinant human erythropoietin (r-huepo) is associated with improved sexual function, we conducted the present study to further delineate the mechanism(s) by which this is brought about. serum prolactin, testosterone, and parathyroid hormone (pth) levels were followed during 4 months of r-huepo therapy. within 4 months of treatment with r-huepo, hematocrit values rose from 23.7 +/- 1.2 to 35.7 +/- 0.2% and hemog ... | 1989 | 2914405 |
| the astroglial response to autonomic tissue grafts. | autonomic (superior cervical) ganglia were grafted either into the iv ventricle where minimal trauma occurred or directly into the cerebral cortex which was necessarily traumatic. previous studies have shown that host astroglia may migrate into autonomic tissue grafts. the purpose of the present study was to compare and contrast the astroglial response in allo- and autografts. by monitoring the host response in the two model sites using glial fibrillary acidic protein (gfap) immunostaining in 1 ... | 1989 | 2914205 |
| effect of altering handle position of a rolling walker on gait in children with cerebral palsy. | the purpose of this study was to determine whether altering the handle position on a rolling walker would affect the gait pattern of children with spastic cerebral palsy (cp). sixteen children with cp (2-10 years old) performed six gait trials, three with the handle on the rolling walker positioned horizontally and three with the handle positioned vertically. using the footprint-on-paper method, gait characteristics of right and left step width, step length, and stride length; cadence; and veloc ... | 2010 | 2913581 |
| an adaptive response of vibrio cholerae strain ogawa 154 to furazolidone. | since furazolidone is an antimicrobial drug, any possibility of its evoking an adaptive response appears to be very important. this response was studied in vibrio cholerae cells as a model system. in order to determine this response, a dose-response relation of these cells to furazolidone and the kinetics of inactivation of the drug were studied. the study of the adaptive response of these cells to furazolidone reveals that cells treated with a low concentration of furazolidone for a particular ... | 1989 | 2913490 |
| rapid identification of vibrio cholerae serotype o1 from primary isolation plates by a coagglutination test. | a coagglutination test was developed for identifying suspected colonies of vibrio cholerae serotype o1 directly from primary isolation plates. visible agglutination occurs when v. cholerae o1 antibody attached to cell-wall protein a of staphylococcus aureus reacts with its homologous antigen. from 314 faecal samples from clinically suspected cases of cholera, 210 colonies from thiosulphate citrate bile salts sucrose (tcbs) agar and 222 colonies from taurocholate tellurite gelatin (ttg) agar were ... | 1989 | 2913315 |
