| social class and preschool language skill: v. cognitive and semantic mastery of number. | this study was done to test the validity of two hypotheses of why children, and especially black children, of families of the poverty sector commonly fail in school. sociologists deny for them either a cognitive or a linguistic deficit, and blame their failures on having to master the unfamiliar dialect of standard english while learning to read. the authors, on the other hand, blame the failures on inadequacies of early preschool experience that result in such deficits as one in semantic master ... | 2005 | 1175915 |

| functional states of various heart segments during protracted hypokinesis in patients with tuberculosis of bones and joints. | by the method of acceleration cinecardiography the effect of hypokinesis on the contracting activity of the left and right heart was studied in 46 patients with tuberculous affections of bones and joints, confined to strict bed rest. as controls here served 40 patients with unrestricted mobility and 33 healthy subjects. it was found that the restriction of mobility and compulsory horizontal body positions of the patients contributed to a rearrangement of the phasic structure of the cardiac cycle ... | 2005 | 544173 |
| effects of professional and media warnings about the association between aspirin use in children and reye's syndrome. | the media played a central role in changing the use of aspirin among children with viral illness following reports of its association with a rare but deadly disease, reye's syndrome (rs). it did so by alerting health professionals and parents about ways to prevent rs in children. indeed, by the time aspirin product labeling was required by the fda in 1986, most of the decline in rs incidence had already occurred. in the past, media-only health education campaigns have been relatively unsuccessfu ... | 2005 | 1316991 |
| hodgkin's disease in childhood. | the histopathologic study of 103 patients with hodgkin's disease including 5 cases who had staging laparotomy during the last 10 years were reviewed. the following conclusions were drawn: 1. no significant sex difference among subtypes were noted. 2. associated glomerulopathy, nephrotic syndromes, and amyloidosis were occasionally found. 3. in childhood lymphomas excluding leukemia are the most frequent malignacies. among the lymphomas, hodgkin's disease predominates. 4. the most frequent subtyp ... | 2004 | 387804 |

| protease and phospholipase inhibition protect veneza zonata (hemiptera coreidae) against septicemia caused by parasite trypanosomatid 563dt. | veneza zonata (hemiptera coreidae) is an insect which causes losses in several crops, and it is also an important vector of lower trypanosomatids. v. zonata specimens were collected on rural properties in londrina, state of paraná, southern brazil. inoculation of leptomonas 563dt into v. zonata hemocoel caused insect death within approximately 24 h, with large bacterial proliferation into their hemocoels. some bacteria which were found in the digestive tract of those insects, such as escherichia ... | 2004 | 14992855 |
| cloning, overexpression, and characterization of a novel thermostable penicillin g acylase from achromobacter xylosoxidans: probing the molecular basis for its high thermostability. | the gene encoding a novel penicillin g acylase (pga), designated pgaw, was cloned from achromobacter xylosoxidans and overexpressed in escherichia coli. the pgaw gene contains an open reading frame of 2586 nucleotides. the deduced protein sequence encoded by pgaw has about 50% amino acid identity to several well-characterized pgas, including those of providencia rettgeri, kluyvera cryocrescens, and escherichia coli. biochemical studies showed that the optimal temperature for this novel pga (pga6 ... | 2004 | 15128530 |
| universal primer pcr with dgge for rapid detection of bacterial pathogens. | a universal primer pcr (uppcr) combined with denaturing gradient gel electrophoresis (dgge) was evaluated as a method permitting the rapid detection of pathogens. the results show that this method is efficient at amplifying the conserved regions of bacterial 16s rrna genes with universal primers and can detect causative bacterial pathogens rapidly. six species of bacteria from fisheries (pseudomonas fluorescens, vibrio anguillarum, aeromonas hydrophila, vibrio fluvialis, providencia rettgeri and ... | 2004 | 15134888 |
| per-1 production in a urinary isolate of providencia rettgeri. | a providencia rettgeri strain resistant to extended-spectrum cephalosporins and intermediate to aztreonam was isolated from the urine of a patient hospitalized in the urology clinic of ssk educational hospital in ankara. clavulanic acid restored the activity of extended-spectrum cephalosporins, suggesting that the strain was harboring an extended-spectrum beta-lactamase. since the per-1 enzyme is widespread in turkey, and had been already detected in a related species such as proteus mirabilis, ... | 2004 | 15332708 |
| metallo-beta-lactamase-producing gram-negative bacilli: laboratory-based surveillance in cooperation with 13 clinical laboratories in the kinki region of japan. | a total of 19,753 strains of gram-negative rods collected during two 6-month periods (october 2000 to march 2001 and november 2001 to april 2002) from 13 clinical laboratories in the kinki region of japan were investigated for the production of metallo-beta-lactamases (mbls). mbls were detected in 96 (0.5%) of the 19,753 isolates by the broth microdilution method, the 2-mercaptopropionic acid inhibition test, and pcr and dna sequencing analyses. mbl-positive isolates were detected in 9 of 13 lab ... | 2004 | 15528723 |
