Neural efficiency analyzer scores of reading disabled, normally reading and academically superior children.

Usefulness, under field-testing conditions, of one version of a Neural Efficiency Analygated. The equipment was said to measure efficiency of information processing as reflected in time between alternate EEG falling zero-crossing points. Special emphasis was placed on the difference score, a measure of right-left hemisphere "efficiency" differences. Contrary to earlier reports, no significant differences were found between such scores of groups of reading disabled, normally reading, and academically superior children. Possible reasons for the negative findings are explored.

Mindless reading: eye-movement characteristics are similar in scanning letter strings and reading texts.

The purpose of the present study was to compare the oculomotor behavior of readers scanning meaningful and meaningless materials. Four conditions were used--a normal-text-reading control condition, and three experimental conditions in which the amount of linguistic processing was reduced, either by presenting the subjects with repeated letter strings or by asking the subjects to search for a target letter in texts or letter strings. The results show that global eye-movement characteristics (such as saccade size and fixation duration), as well as local characteristics (such as word-skipping rate, landing site, refixation probability, and refixation position), are very similar in the four conditions. The finding that the eyes are capable of generating an autonomous oculomotor scanning strategy in the absence of any linguistic information to process argues in favor of the idea that such predetermined oculomotor strategies might be an important determinant of eye movements in reading.

Reading the medical record. I. Analysis of physicians' ways of reading the medical record.

Physicians were interviewed about their routines in everyday use of the medical record. From the interviews, we conclude that the medical record is a well functioning working instrument for the experienced physician. Using the medical record as a basis for decision making involves interpretation of format, layout and other textural features of the type-written data. Interpretation of these features provides effective guidance in the process of searching, reading and assessing the relevance of different items of information in the record. It seems that this is a skill which is an integrated part of diagnostic expertise. This skill plays an important role in decision making based on the large amount of information about a patient, which is exhibited to the reader in the medical record. This finding has implications for the design of user interfaces for reading computerized medical records.

A new computerized method of reading sperm morphology (strict criteria) is as efficient as technician reading.

OBJECTIVES: To compare the ability of a computerized method of sperm morphology with the manually recorded method in predicting in vitro fertilization (IVF) results, to compare results obtained by both methods, and to determine the intraobservation variability. DESIGN, SETTING, PATIENTS: Forty-three stained semen slide preparations from two large level-three academic institutions' reproductive endocrinology units (IVF programs) were blindly evaluated, and the sperm were classified into normal and amorphous forms. RESULTS: Experiment 1: Twenty-one slide preparations from the Tygerberg gamete intrafallopian transfer program were manually evaluated; the fertilization rates for the groups with < 14% and > 14% normal sperm forms were 33.3% (15/45 oocytes) and 76.6% (46/60 oocytes), respectively. Corresponding fertilization rates with FERTECH were 46.8% (30/64) and 75.6% (31/41). Experiment 2: Twenty-two slide preparations from the Norfolk IVF program were evaluated. The manual method reported a fertilization rate in the group with < 14% normal forms of 27.4% (14/51 oocytes) compared with 90.0% (127/141 oocytes) in the group with > 14% normal forms. Corresponding figures for the FERTECH method were 33.9% (18/53) and 88.4% (123/139), respectively. Experiment 3: When the 43 slide preparations were blindly evaluated using both methods, 84% of the FERTECH evaluations correlated well with the manual method and FERTECH ability to diagnose the subfertile male (< 14% normal forms) was 95% (sensitivity). Experiment 4: A total of 16 different slides (8 per group) were randomly selected and analyzed five times (100 cells per reading) by the computerized method. The slides were obtained from men with normal sperm morphology of < 14% and > 14% as classified by the manual method. In the first group (< 14%) 97.5% (39/40) of the readings classified the sperm in the proper category, whereas in the second group (> 14%) 95% (38/40) of the cases were correctly identified. CONCLUSION: Using strict criteria for morphology evaluation, there is a positive and significant correlation between FERTECH evaluation and manual assessment. The reproducibility of the computerized method and the ability to distinguish between fertile and subfertile groups using those criteria are good.

The complete sequence of a 33 kb fragment on the right arm of chromosome II from Saccharomyces cerevisiae reveals 16 open reading frames, including ten new open reading frames, five previously identified genes and a homologue of the SCO1 gene.

We report here the sequence of a 33,117 bp DNA fragment located approximately 30 kb from the centromere on the right arm of Saccharomyces cerevisiae chromosome II. We have detected 16 open reading frames (ORFs) longer than 450 bp, provisionally called YBR0301 to YBR0322, covering 70.4% of the entire sequence. The ORFs YBR0301, YBR0302, YBR0303, YBR0305 and YBR0315 correspond to previously sequenced S. cerevisiae genes GAL10, GAL1, FUR4, CAL1 and L2B, respectively. Translation products of two other ORFs, YBR0308 and YBR0312 exhibit similarity to previously known S. cerevisiae proteins: the mitochondrially associated protein SCO1 and the protein kinase YKR2. The predicted protein product of the ORF YBR0321 shows a 41.6% identity score with the Escherichia coli pyroxamine 5'-phosphate oxidase. The nine other ORFs show no significant homology to known proteins.

Human herpesvirus 8 open reading frame 26 and open reading frame 65 sequences from multiple myeloma patients: a shared pattern not found in Kaposi's sarcoma or primary effusion lymphoma.

Human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus, has been implicated in the pathogenesis of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman's disease, and recently multiple myeloma (MM). DNA sequence analyses of HHV-8 suggest that multiple HHV-8 strains exist. We extracted DNA from 24 patients with MM and 3 patients with monoclonal gammopathy of undetermined significance and compared HHV-8 open reading frames (ORFs) 26 and 65 sequences with those derived from patients with KS, PEL, and two HHV-8-positive PEL cell lines KS-1 and BC-1. ORF26 sequence data suggest that MM patients are consistently carriers of HHV-8 strain subtype C3. All MM patients also consistently revealed either a single bp deletion or substitution at position 112197 in ORF65. This unique alteration is not present in patients with KS or PEL or in PEL cell lines. It occurs in the portion of ORF65 that is known to be responsible for a serological response to HHV-8.

How to read clinical journals: X. How to react when your colleagues haven't read a thing.

Physicians receive little instruction on how to interact with colleagues, and even less guidance on what to do when their colleagues are poorly informed. Eight techniques are presented here that may be of use in dealing with colleagues who have clearly not read the literature and are unable to maintain the facade that they have. If employed properly and used judiciously, these techniques may help avoid embarrassment for all and may also improve the exchange of valuable information between professionals.

Is the Autorefractor reading closest to manifest refraction? A comparison of the patient's previous spectacles and the 6600 Autorefractor reading.

In a study of 56 patients, the old glasses of a previously refracted individual were as close to the final subjective refraction as the reading obtained with a 6600 Autorefractor. Therefore, the previous spectacle correction might logically be used for the starting point of a subjective refraction, with retinoscopy or automatic refractor results being used for this purpose in patients whose previous spectacle refraction is unknown or in the first refraction of an aphakic patients.

Cognitive factors at school entry predictive of specific reading retardation and general reading backwardness: a research note.

A sample of 453 Australian children was followed over the first three years of schooling. A broad range of cognitive skills was assessed at the beginning of the first year at school and at the end of the third year the children were classified as retarded, backward or normal readers. At school entry, backward readers were found to be deficient in a broad range of cognitive skills, as might be expected given their lower IQs. Retarded readers, however, were found to be deficient on a more limited range of tasks, mainly involving early literacy and phonological processing skills. The implications of these findings for theories of cognitive deficit in reading retardation are discussed.

Do hourly averaged pH readings correlate with those from point readings of aspiration? Comparison of two different electrode positions with simultaneous aspiration.

Hourly averaged data from continuous intraluminal pH recording were compared with the point aspiration in five 24-hour studies performed on healthy volunteers. Two different electrode positions were compared simultaneously with aspiration. The correlation was performed using the median from the whole hour's recording of the electrode against the aspiration point. There was a significant correlation between both electrodes and aspiration (p less than 0.001), although both electrodes read consistently lower than aspiration: electrode A (gastric antrum), median pH = 1.4; electrode B (gastric body), pH = 1.9; aspiration, pH = 2.3. These findings show that data reported in clinical trials using different recording techniques are not directly comparable and must be interpreted appropriately. The position of the electrode may also be important.
