quantitation of skin bacteria: lethality of the wash solution used to remove bacteria.a widely used technique for the quantitative removal of bacteria from the skin uses a detergent, triton x-100 (p, t-octylphenoxynonaethoxyethanol), to remove and suspend the bacteria. we determined the half-life for the survival of five common skin bacteria suspended in the solution. the shortest-lived was streptococcus pyogenes with a half-life of 0.9 hours. all of the others (propionibacterium acnes, staphylococcus epidermidis, staphylococcus aureus, and klebsiella pneumoniae) had half-lives o ...197993373
adjuvant effect of a peptidoglycan attached covalently to a synthetic antigen provoking anti-phage antibodies.the synthetic antigen denoted p2-a--l, comprising the fragment p2 of the coat protein of ms-2 coliphage attached to multichain poly-dl-alanine, served for the immunization of guinea-pigs. immunization was carried out either in phosphate buffered saline (pbs) or in freund's incomplete adjuvant (fia) in the presence or absence of a small molecular weight peptidoglycan prepared from bacillus megaterium, which was checked for its adjuvant effect. the various antisera were assessed by their capacity ...1978101440
beta-galactosidase and selective neutrality.three hypotheses to explain the amino acid composition of proteins are inconsistent (p congruent to 10(-9) with the experimental data for beta-galactosidase from escherichia coli. the exceptional length of this protein, 1021 residues, permits rigorous tests of these hypotheses without complication from statistical artifacts. either this protein is not at compositional equilibrium, which is unlikely from knowledge about other proteins, or the evolution of this protein and its coding gene have not ...1979106468
[age and season related dynamics of vitamin e levels in the serum of young cattle from birth to the age of 22 months].the dynamics of serum vitamin e levels in heifers was followed for 22 months. we found that calves were born with a very low, almost nil, content of this vitamin (on an average 0.029 mg%) as a result of the limited diaplacental transfer from the mother to the fetus. in the following period of extrauterine life and growing up of the young cattle conspicuous age dynamics was recorded which is, however, linked or affected by the seasons. colostral nutrition which is reflected in the increasing seru ...1979106508
local antivirals in a herpes simplex stromal keratitis model.a herpes simplex stromal keratitis rabbit model, which was produced by intrastromal injection of live virus, was used to evaluate the effects of local antivirals on the natural course of the disease. topical trifluridine (trifluorothymidine) and vidarabine monophosphate (adenine arabinoside monophosphate), when given early and frequently, suppressed the disease, indicating that viral replication was important in initiating the disease. however, seven days after the stromal disease had begun to d ...1979106813
physiological and genetic modifications of the expression of the yeast mitochondrial adenosine triphosphatase inhibitor.1. the oligomycin-sensitive atpase activity of submitochondrial particles of the glycerol-grown "petite-negative" yeast: schizosaccharomyces pombe is markedly stimulated by incubation at 40 degrees c and by trypsin activations are treatment. both increased in triton-x 100 extracts of the submitochondrial particles. 2. a trypsin-sensitive inhibitory factor of mitochondrial atpase with properties similar to that of beef heart has been extracted and purified from glycerol-grown and glucose-grown s. ...1975123768
biological properties of the peptidoglycan.this review deals with those biological activities of peptidoglycan that are not directly analogous to the properties of gram-negative bacterial endotoxin. the report is divided into 3 major parts: 1. a survey of peptidoglycan activities such as the induction of inflammatory skin reactions, lesion-enhancing activity (virulence factor), inhibition of phagocytosis of bacteria, inhibition of cell migration, cytotoxicity to mammalian cells, potentiation of the humoral and cellular immune response (a ...1975126557
[the protective effect of magnesium-aspartate-procaine cardioplegia on the hypertrophied left ventricle of the mini-pig (author's transl)].after induction of left ventricular hypertrophy by supravalvar constriction of the ascending aorta in mini pigs (atp and lactate) were measured under different cardioplegic conditions. in normothermia and plain anoxic arrest atp decrease and lactate increase were significantly slower in hypertrophied myocardium compared to normal myocardium. injection cardioplegia using magnesium-aspartate-procaine at 37 degrees c did not influence the atp decrease and lactate increase in the hypertrophied ventr ...1978150067
scanning electron microscopy of interaction of peripheral blood lymphocytes from colonic cancer patients with human colonic cancer-derived cells; p-4788.peripheral blood lymphocytes and the various lymphocyte fractions from patients with cancer of the colon were cultivated with target cells (p-4788) derived from the colon cancer. changes in the surface ultrastructure during tumor cell destruction were studied by scanning electron microscopy (sem). p-4788 cells adhering to the coverslip showed various surface activity. the surfaces of some cells were relatively flat; others were smooth or had fine granules. still other cells were villous, round o ...1979161468
catabolite inactivation of phosphoenolpyruvate carboxykinase in spheroplasts from saccharomyces cerevisiae.catabolite inactivation of phosphoenolpyruvate carboxykinase was studied in yeast spheroplasts using 0.9 m mannitol or 0.6 m potassium chloride as the osmotic support. in the presence of potassium chloride the rate of catabolite inactivation was nearly the same as that occurring in intact yeast cells under different conditions of incubation. however, in the presence of mannitol, catabolite inactivation in spheroplasts was prevented. the mannitol inhibition of catabolite inactivation was released ...1979383159
thallium-201 accumulation by epidermoid inclusion cyst.an elderly male undergoing re-evaluation for coronary artery disease demonstrated an extra-cardiac focus of 201tl accumulation during the performance of a planar myocardial perfusion scan. this corresponded to a subcutaneous lesion of the left posterior thorax found on a concurrent computerized axial tomographic (cat) scan and upon surgical excision proved to be an "epidermoid inclusion cyst." a follow-up nuclear scan failed to reveal any residual extracardiac tracer localization. confusing this ...19921403158
detection of mycobacterium tuberculosis antigen 5 in cerebrospinal fluid by inhibition elisa and its diagnostic potential in tuberculous meningitis.inhibition elisa was used to quantitate mycobacterium tuberculosis antigen 5 in cerebrospinal fluid (csf) specimens of 40 patients with a clinical diagnosis of tuberculous meningitis. in all 10 culture-proven patients, the assay was positive; in 30 culture-negative patients, the assay yielded positive results for 21. csf antigen 5 concentrations ranged from 9 to 82 ng/ml (mean +/- sd, 45.5 +/- 6.2). in 40 patients with nontuberculous neurologic diseases, mean concentration was 1.45 ng/ml. thus, ...19911899876

a molecular strategy for the study of bacterial invasion.bacterial populations are often clonal, and even within a bacterial species, the frequency of gene exchange and recombination is quite low. consequently, mobile genetic elements--plasmids, bacteriophages, and transposons--have been the central factors in the evolution of pathogenic traits. one central feature of pathogenicity, the capacity to enter epithelial cells, is encoded by the bacterial chromosome of yersinia pseudotuberculosis but by plasmid genes in enteroinvasive escherichia coli. a si ...19872825322
[human chorionic prealbumin: its identification, physicochemical properties and detection in the blood serum in trophoblastic disease].human chorionic prealbumin (hcpa) was immunochemically identified and isolated in pure form from immature placenta, particularly, from chorion. comparative immunodiffusion analysis shows that hcpa differs from the known placenta-specific proteins. hcpa is a glycoprotein with mw about 100 kd determined by gel-filtration and 45 kd by sds polyacrylamide gel electrophoresis. by immunodiffusion hcpa was not found in fetal and adult tissues and in biological fluids. hcpa was discovered in patients wit ...19882848598
suppression of sv40-promoted gene expression by differentiation of preadipose cells.when a plasmid bearing the chloramphenicol acetyltransferase (cat) gene under the control of an sv40 early promoter is introduced into preadipose or adipose cells of line 3t3-f442a, the promoter directs high levels of transient expression of cat. however, when the plasmid is introduced into preadipose cells and the cells are then allowed to differentiate into adipose cells, the expression of the cat gene is suppressed. in this process, the plasmid is not changed detectably in amount, topology, o ...19882849579
a murine monoclonal antibody raised against human non-small cell carcinoma of the lung.murine monoclonal antibodies (mabs) reactive with human non-small cell carcinoma of the lung (nsccl) were produced following immunization with a membrane preparation of calu-3, a human adenocarcinoma of the lung cell line grown in nude mice. positive hybrids unreactive with normal liver membranes and human peripheral white blood cells were selected for further testing. one mab (rs5-4h6) recognized an antigen expressed in a variety of lung and other carcinoma cell lines as detected by flow cytome ...19882853133
purification of carp growth hormone and cloning of the complementary dna.the growth hormone (gh) was isolated and purified from common carp (cyprinus carpio) pituitary glands by salt precipitation and hplc on reverse-phase c18 columns. the carp gh cdna was synthesized and cloned in escherichia coli using ecori linkers and pbr322 as vector. the positive clones were selected and sequenced. the full-length carp gh cdna contains 1187 nucleotide basepairs with an open reading frame coding for the precursor form carp gh of 210 amino-acid residues. the partial amino-acid se ...19892920175
diabetic embryopathy and fuel-mediated organ teratogenesis: lessons from animal models.the growing recognition that faulty maternal metabolism during early organogenesis may be implicated in the increased incidence of birth defects in pregnancies complicated by diabetes has prompted worldwide efforts to institute improved preconceptional metabolic regulation. however, the failure to identify the periods of greatest risk for diabetic embryopathy, the mediating teratogen(s), and the underlying mechanisms have complicated attempts to establish precise therapeutic guidelines and targe ...19883053387

localization and quantification of nonapeptide binding sites in the kidney of xenopus laevis: evidence for the existence of two different nonapeptide receptors.the distribution and properties of nonapeptide binding sites in the kidney of the anuran xenopus laevis were investigated using quantitative in vitro autoradiography. the binding studies were performed with [3h]arginine vasopressin (avp) as ligand because [125i]arginine vasotocin (avt) lacks biological activity. specific binding sites for [3h]avp are located in the glomeruli of the kidney. [3h]avp binding results in a steady state of association and dissociation between ligand and binding sites. ...19921563620

influence of antibiotics on the faecal excretion of bile pigments in healthy subjects.we have evaluated the effects of 10 antibiotics, given orally for 6 days to healthy subjects, on faecal excretion of urobilinogen. intake of bacitracin, vancomycin, clindamycin, erythromycin, and ampicillin resulted in a pronounced suppression of the faecal excretion of urobilinogen (p less than 0.05). intake of doxycycline, metronidazole, nalidixic acid, ofloxacin, and trimethoprim/sulphamethoxazole had no significant effect. the effects of three antibiotics-ampicillin, clindamycin, and metroni ...20133775264
predictive behavior of optokinetic eye movements.optokinetic nystagmus is often thought of as a "primitive" oculomotor response, while smooth pursuit is thought of as a "higher" one. we have used conditions that are usually thought of as eliciting optokinetic responses; i.e., large-field stimuli confined to the retinal periphery, and instructions to subjects to respond passively. in spite of this, the responses showed predictive behavior similar to that described for smooth pursuit.20103224671
hepatic injury in chronic iron overload. role of lipid peroxidation.in both hereditary hemochromatosis and in the various forms of secondary hemochromatosis, there is a pathologic expansion of body iron stores due mainly to an increase in absorption of dietary iron. excess deposition of iron in the parenchymal tissues of several organs (e.g. liver, heart, pancreas, joints, endocrine glands) results in cell injury and functional insufficiency. in the liver, the major pathological manifestations of chronic iron overload are fibrosis and ultimately cirrhosis. evide ...20092663196

[use of chickpea (cicer arietinum l.) in non-dairy formulas. ii. nitrogen balance in children with lactose intolerance, fed with a formula based on chickpea and a commercial soybean product].the nutritive value of chick-pea and soy infant formulas was evaluated. nitrogen balance was performed in 17 malnourished babies, seven of which were fed with the chick-pea formula, and 10 with the soy commercial formula (sobee). the percentage of absorption, retention and biological value of the chick-pea formula were 72.4, 26.4 and 35.1, respectively and 69.6, 24.3 and 34.0 in the same order, with the soy formula. since the nutritional quality of the chick-pea was not different to the commerci ...20113146951

depletion of monoamine transmitters by tetrabenazine in brain tissue in huntington's disease.the neurochemical effect of tetrabenazine was assessed by determining the levels of dopamine, noradrenaline and 5-hydroxytryptamine and their metabolites in post-mortem brain from huntington's disease patients with or without a history of tetrabenazine treatment. the tetrabenazine-treated group showed a general description of monoamines in all regions studied, the greatest reduction being dopamine in the caudate. this provides the basis for the effect of tetrabenzine on chorea, while monoamine l ...20102901681
silver staining of native and denatured eucaryotic dna in agarose gels.a modified method of silver staining for native and denatured eucaryotic dna in 1% agarose gel is described. this method is at least fivefold more sensitive than ethidium bromide staining, with a detection limit of 2.5 ng for total dna. the calibration curve is linear within the range 5-30 ng of single-stranded and double-stranded dna. this method is especially advantageous for electrophoretic assessment of dna molecular weights.20082446526
effects of physical conditioning on the heart size and wall thickness of college women.m-mode echocardiograms were obtained from 40 sedentary college women, 8 sprinters, 6 distance runners, 10 swimmers, 9 basketball players, 8 dancers, and 10 sedentary men (ages 19 to 31 yr). treadmill stress tests were performed by all groups except the basketball players. the aerobic capacities of the athletes were 30 to 48% greater (p less than 0.05) than the sedentary subjects. the athletes exhibited trends toward higher than average left ventricular (lv) end-diastolic dimensions (7 to 25%), l ...20133683147
