anorectal functioning in fecal incontinence.manometric testing was performed on three groups of subjects: 14 patients complaining of fecal incontinence, 14 age- and sex-matched continent patients, and 14 sex-matched younger normal controls. the younger group displayed significantly stronger contractions of the external anal sphincter and puborectalis than the two patient groups, which did not differ. no differences were found in the relaxation of the internal and sphincter. the incontinent group required a significantly larger stimulus in ...20123338357
demonstration of phosphatidylinositol anchors on ly-6 molecules by specific phospholipase c digestion and gel electrophoresis in octylglucoside.release by phosphatidylinositol-specific phospholipase c is frequently provided as evidence for membrane anchorage of a protein through phosphatidylinositol. demonstration that the enzyme removes a lipophilic moiety from the protein is stronger evidence, and is presented here for members of the ly-6 family of lymphocyte antigens: ly-6a, c and e. treatment of these molecules with the enzyme greatly increased their electrophoretic mobilities on polyacrylamide gels containing nonionic detergent. fu ...20123318830
optimal bandpass filters for time-domain analysis of the signal-averaged electrocardiogram.the optimal bandpass filter for signal averaging of the surface qrs complex to detect late potentials is undefined. a study was conducted in 87 patients; 25 (mean age 34 +/- 10 years) were normal (group i), 29 (60 +/- 20 years) had organic heart disease without ventricular tachycardia (group ii) and 33 (62 +/- 15 years) had sustained ventricular tachycardia (group iii). in all patients signal-averaged electrocardiography (200 beats) was performed using a sharp, bidirectional filter and data anal ...20123318369
effect of fibric acid derivatives on blood lipid and lipoprotein levels.the literature for the last seven years was reviewed in terms of the effect of the various fibric acid derivatives on blood lipid and lipoprotein levels. the criteria for review resulted in a greater focus on three of the newer fibric acid derivatives: bezafibrate, ciprofibrate, fenofibrate. in type ii a hyperlipoproteinemia, all fibric acid derivatives produce modest reductions in total plasma cholesterol and low-density lipoprotein cholesterol. the evidence suggests that bezafibrate, ciprofibr ...20123318453
treatment of blastic transformation of chronic myelogenous leukemia with mitoxantrone.twenty-four patients with blastic-phase chronic myelogenous leukemia (cml) were treated with mitoxantrone. the patients included 19 whose cells were philadelphia chromosome (ph1+) and 5 who were either ph1- or in whom cytogenetics were not available. six of the 19 whose cells were ph1+ responded and one of those who were ph1- responded. the patients were further characterized into lymphoid or nonlymphoid on the basis of terminal deoxynucleotidyl transferase or morphology. two of the patients wit ...20123459595
congenital deficiency of the tibia.the late results of treatment of 24 legs in 21 children with congenital deficiency of the tibia are presented. a new classification is proposed which correlates well with recommendations for treatment and with the final functional result. three types of deficiency were recognised: type i, total absence of the tibia; type ii, distal absence; type iii, distal deficiency with tibiofibular diastasis. the early radiographic appearances, the functional status of the quadriceps and the severity of flex ...20124030854

recording dowel pin position with plastic logs.six readily available plastic materials were evaluated for use as a log for locating the ends of die dowel pins. seven criteria were divided into two main categories of adherence qualities of the material and useability. cost was the third category evaluated and compared. color and availability were also considered. forty-two sophomore dental students accomplished 84 evaluations. plasticine and weatherstrip caulking cord were found to meet all criteria best.20123511239
normal cholesterol levels with lovastatin (mevinolin) therapy in a child with homozygous familial hypercholesterolemia following liver transplantation.patients with homozygous familial hypercholesterolemia produce no normal low-density lipoprotein (ldl) receptors, and as a result, ldl accumulates in plasma, causing severe premature atherosclerosis. two years ago, liver transplantation was performed in a child with homozygous familial hypercholesterolemia, restoring ldl receptor activity to about 60% of normal and reducing the ldl cholesterol level by 81%. however, the patient's lipoprotein levels remained significantly elevated for her age and ...20123534334
hemiretinal differences in speed of light detection in esotropic amblyopes.nine esotropic amblyopes were tested monocularly in a simple reaction time (rt) paradigm with brief suprathreshold flashes of light presented at various eccentricities along the horizontal meridian of the nasal or temporal hemiretinae. all were clinically amblyopic in one eye only. rt was significantly longer in the amblyopic than in the other eye at 1, 5 and 10 deg but not at 25 and 35 deg from the fovea. another clearcut finding concerned hemiretinal differences: in the non-amblyopic eye, as i ...20123414004

prevalence and antibiotic susceptibility of bacteroides fragilis group isolated from stool samples in north lebanon.fifty one strains of the bacteroides fragilis group were isolated from 45 fecal samples. classical phenotypic identification showed that 16 isolates were b. thetaiotaomicron, 12 b. uniformis, 9 b. eggerthii, 7 b. vulgatus, 3 b. caccae, 2 parabacteroides distasonis with 1 identified b. ovatus and 1 b. fragilis. the 51 strains were tested for susceptibility against 16 antimicrobial agents and the mics for metronidazole were determined. the tests showed that imipenem, meropenem and chloramphenicol ...201324516449
discovery of β-1,4-d-mannosyl-n-acetyl-d-glucosamine phosphorylase involved in the metabolism of n-glycans.a gene cluster involved in n-glycan metabolism was identified in the genome of bacteroides thetaiotaomicron vpi-5482. this gene cluster encodes a major facilitator superfamily transporter, a starch utilization system-like transporter consisting of a tonb-dependent oligosaccharide transporter and an outer membrane lipoprotein, four glycoside hydrolases (α-mannosidase, β-n-acetylhexosaminidase, exo-α-sialidase, and endo-β-n-acetylglucosaminidase), and a phosphorylase (bt1033) with unknown function ...201323943617
characterization of adherent bacteroidales from intestinal biopsies of children and young adults with inflammatory bowel disease.there is extensive evidence implicating the intestinal microbiota in inflammatory bowel disease [ibd], but no microbial agent has been identified as a sole causative agent. bacteroidales are numerically dominant intestinal organisms that associate with the mucosal surface and have properties that both positively and negatively affect the host. to determine precise numbers and species of bacteroidales adherent to the mucosal surface in ibd patients, we performed a comprehensive culture based anal ...201323776434
major phenylpropanoid-derived metabolites in the human gut can arise from microbial fermentation of protein.plant secondary metabolites, such as phenolic acids are commonly associated with benefits for human health. two of the most abundant phenylpropanoid-derived compounds detected in human faecal samples are phenylacetic acid (paa) and 4-hydroxylphenylacetic acid (4-hydroxypaa). although they have the potential to be derived from diets rich in plant-based foods, evidence suggests that these compounds can be derived from the microbial fermentation of aromatic amino acids (aaas) in the colon.201323349065
analysis of a novel 8.9kb cryptic plasmid from bacteroides uniformis, its long-term stability and spread within human microbiota.the analysis of plasmid content in dominant bacteroidales order intestinal strains isolated from the same child at a 5 year interval identified a 8.9 kb plasmid in bacteroides uniformis bun24 strain isolated at age 6 and indistinguishably sized plasmids in the isolates of b. uniformis, b. vulgatus, b. intesinalis, and parabacteroides distasonis at age 11. we sequenced a b. uniformis bun24 plasmid, designated pbun24, and using molecular surveys of diverse species we established that this 8944bp m ...201323201047
protein function annotation with structurally aligned local sites of activity (salsas).the prediction of biochemical function from the 3d structure of a protein has proved to be much more difficult than was originally foreseen. a reliable method to test the likelihood of putative annotations and to predict function from structure would add tremendous value to structural genomics data. we report on a new method, structurally aligned local sites of activity (salsa), for the prediction of biochemical function based on a local structural match at the predicted catalytic or binding sit ...201323514271
protein substrates of a novel secretion system are numerous in the bacteroidetes phylum and have in common a cleavable c-terminal secretion signal, extensive post-translational modification, and cell-surface attachment.the secretion of certain proteins in porphyromonas gingivalis is dependent on a c-terminal domain (ctd). after secretion, the ctd is cleaved prior to extensive modification of the mature protein, probably with lipopolysaccharide, therefore enabling attachment to the cell surface. in this study, bioinformatic analyses of the ctd demonstrated the presence of three conserved sequence motifs. these motifs were used to construct hidden markov models (hmms) that predicted 663 ctd-containing proteins i ...201324007199
flx pyrosequencing analysis of the effects of the brown-algal fermentable polysaccharides alginate and laminaran on rat cecal microbiotas.edible brown algae are used as major food material in far east asian countries, particularly in south korea and japan. they contain fermentable dietary fibers, alginic acid (uronic acid polymer) and laminaran (β-1,3-glucan), that are fermented into organic acids by intestinal bacteria. to clarify the effect of edible algae on the intestinal environment, the cecal microbiotas of rats fed diets containing no dietary fiber (control) or 2% (wt/wt) sodium alginate or laminaran for 2 weeks were analyz ...201323183985
appearance of adenosine triphosphate in the perfusate from working frog heart.frog hearts (rana pipiens) were perfused in situ with ringer's solution and the perfusate tested on firefly extract for the presence of atp. at a normal perfusion pressure of 8 cm. h2o the rate of release of atp into the perfusate was 8.8 (+/- s.e.1.7) pmoles.min-1. when the workload was increased by raising the perfusion pressure to 12 cm. h2o the rate of release increased to 28.3 (+/- s.e.4.8) pmoles.min-1. the rate of release was found to be proportional to the amount of workload imposed upon ...20133877270

limitations in hardware design in impedance imaging.the collection of data suitable for impedance imaging is a well defined task. once the number of electrodes is chosen, it is possible to specify the number of independent measurements which must be made. having done so, a data collection system can be designed; preferably with the view to both maximising the speed of data collection and minimising the noise on the measurements. the former is desirable to eliminate aliasing when taking measurements on regions in which the conductivity varies with ...20133568576
treatment of idiopathic hypercalciuria with indapamide.twenty-six patients with idiopathic hypercalciuria (urine calcium level greater than 300 mg/24 h [7.5 mmol/d]) were treated with indapamide (a nonthiazide diuretic), 2.5 mg/d for 3 consecutive months. a mean decrease in urine calcium levels of 52% was noted (p less than 0.05). when therapy with indapamide was stopped, the calcium levels returned to pretherapy values. the effect of indapamide on urine calcium levels was similar to that of hydrochlorothiazide in 10 patients who were receiving the ...20133719496
