Sensitivity to onset and rhyme does predict young Children's reading: a comment on Muter, Hulme, Snowling, and Taylor (1997)

Muter, Hulme, Snowling, and Taylor (1997) claimed that measures of phoneme segmentation, and not measures of rhyme, predict young children's reading. They base this claim on the relative predictive success of two rhyme and two phoneme segmentation tasks. However, there is a problem with one of their two rhyme measures, the Rhyme Detection measure. The children were asked to select a choice word which "rhymes with or sounds like" a target word, but the authors only scored rhyme choices ("boat"-"coat") as correct. Choices of words with the same onset as the target ("train"-"tractor") were counted as mistakes, even though these latter choices also shared a common sound with the target. A better way to score the task is to count onset as well as rhyme choices as correct. The new score predicts reading and spelling as well as the phoneme tasks. This result is consistent with the hypothesis of Goswami and Bryant (1990) that sensitivity to onset and rhyme, as well as awareness of phonemes, plays a part in children's success in reading and to spelling.

Cortical connections of the frontoparietal opercular areas in the rhesus monkey

The connections of the frontoparietal opercular areas were studied in rhesus monkeys by using antero- and retrograde tracer techniques. The rostral opercular cortex including the gustatory and proisocortical motor (ProM) areas is connected with precentral areas 3, 1, and 2 as well as with the rostral portion of the opercular area which resembles the second somatosensory type of cortex (area SII) and the ventral portion of area 6. Its distant connections are with the ventral portion of prefrontal areas 46, 11, 12, and 13 as well as with the rostral insula and cingulate motor area (CMAr). The mid opercular region (areas 1 and 2) is connected with pre- and postcentral areas 3, 1, and 2 as well as SII. Additionally, it is connected with the ventral portion of area 6, area 44, area ProM, the gustatory area, and the rostral insula. Its distant connections are with area 4, the ventral portion of area 46, area 7b, and area POa in the intraparietal sulcus (IPS). The rostral parietal opercular region is connected with the postcentral portions of areas 3, 1, and 2; areas 5, 7, and SII; the gustatory area; and the vestibular area. Its other connections are with area 4, area 44, the ventral portion of area 46, area ProM, CMAr, and the supplementary motor area (SMA). The caudal opercular region is connected with the dorsal portion of area 3; areas 2, 5, and 7a; and areas PEa as well as IPd of IPS. It is also connected with area SII, insula, and the superior temporal sulcus. Its distant connections are with area 44; the dorsal portion of area 8 and the ventral portion of area 46; as well as CMAr, SMA, and the supplementary sensory area. This connectivity suggests that the ventral somatosensory areas are involved in sensorimotor activities mainly related to head, neck, and face structures as well as to taste. Additionally, these areas may have a role in frontal (working) and temporal (tactile) memory systems.     

The interaction of peripheral blood leukocytes with alpha1-acid glycoprotein, its carbohydrate chains and neoglycoconjugates

The interaction of human peripheral blood leukocytes with alpha 1-acid glycoprotein (AGP), its glycoforms as well as neoglyco-conjugates representing carbohydrate chains of AGP or its fragments was studied by flow cytometry. It was shown that the main target cells for AGP as well as for conjugates of its carbohydrate chains with polyacrylamide (PAA) are monocytes and polymorphonuclear leukocytes but not lymphocytes. The interaction of AGP with monocytes and granulocytes are mediated by its carbohydrate chains: the binding of AGP with cells was inhibited by AGP, AGP oligosaccharides as well as conjugates of oligosaccharides and its fragments with PAA. The data obtained show the existence of monocyte (and granulocyte) receptors which interact with complex type sialooligosaccharides of AGP.

Connection between disease progress and coping with stress in patients with retinopathy centralis serosa

To illuminate the disease progression in retinopathy centralis serosa, 50 patients were enrolled in a basic study. Evaluated data included medical and sociodemographic data as well as data regarding the patient's coping with everyday conflicts and the disease. Hence, the German multidimensional coping inventory (SVF, Janke, Erdmann u. Boucsein 1985), measuring the trait aspects of coping with everyday troubles, as well as the German coping questionnaire (EFK, Franke 1997), dealing with coping with retinopathy, were applied. We described three different clusters of patients according to active and passive coping strategies. These three clusters also differed in terms of coping with the disease as well as in ophthalmological parameters. To illuminate the individual situation of the members of the clusters, we discuss the specific situation of three patients.

The electrophysiological indices of the state of the different sections of the auditory analyzer in persons with a normal voice and with functional voice disorders]

Individuals with normal voice and patients with voice functional impairments undergone electrophysiological investigation of various parts of the hearing system, using tone audiometry, including the extended frequency band (10, 12, 14 and 16 kHz), as well as short- and long-latency acoustic evoked potentials (SLAEP and LLAEP). It was found out, that individuals with voice functional impairments had all of their hearing system's parts impaired to various extent, with more marked impairments in the central, rather than in the peripheral part of the hearing system. It was shown, that hearing at 4-8 kHz, as well as with the extended frequency band, especially at 14-16 kHz, time patterns of acoustic evoked potentials (latencies of waves III and V of SLAEP, the interpeak interval I-V, as well as the latency periods of the LLAEP components P2 and N2) could be useful in professional selection of individuals of voice and speech professions and for solving labor expertise matters. Of those individuals with normal voice but systematic vocal stress, 17.5% had impaired hearing at 14 and 16 kHz, as well as significant latency prolongation of the LLAEP wave N2 with tone stimulation at 1 and 4 kHz. Apparently, individuals of voice and speech professions should be referred to as the "risk" group. It may well be, that extended band audiometry and acoustic evoked potentials time patterns could be useful in determining the thresholds between the normality and pathology in voice dysfunctions.     

Community health in eastern Africa--and the East African Medical Journal''s contribution over seventy years

Antineutrophil antibodies may be found in the sera of patients with chronic neutropenia as well as in the sera of a variety of patients with neutropenia and associated autoimmune or infectious disorders. We evaluated an immunofluorescent flow cytometric technique for the measurement of antineutrophil antibodies in serum. Sera from patients with suspected immune neutropenia were studied and compared with a group of sera from normal healthy individuals, as well as with sera from patients with rheumatoid arthritis and systemic lupus erythematosus. Of 159 patients with suspected immune neutropenia and a variety of associated clinical disorders, 59 (37%) were found to have evidence for enhanced binding of IgG to normal target neutrophils, interpreted as positive for antineutrophil antibodies. Whereas 0/37 non-neutropenic patients with typical RA had positive results, 51/244 (21%) of sera from nonneutropenic patients with SLE or other collagen vascular disorders showed enhanced IgG binding to neutrophils. Living neutrophils were used to study the effects of cellular activation, and increased antibody binding was observed with certain sera that contained IgG directed against activation-dependent antigens. We found that, under controlled conditions, flow cytometry can be reliably used to detect antineutrophil autoantibodies, with unfixed, living neutrophils as antigenic targets.     

The characteristics of disorders of intracardiac hemodynamics and hemorheology in pulmonary heart failure

Overall ninety patients with chronic obstructive bronchitis presenting with signs of varying degree cardiopulmonary insufficiency (CPI) were evaluated by radionuclide ventriculography with technetium pertechnetate as well as by rotational viscosimetry of blood. The degree of hemorheological derangements tended to get higher with CPI severity (light, moderately severe, severe) being accompanied by progressing impairement of systolic and diastolic functions of both ventricles of the heart. Mechanisms of compensation of endocardiac hemodynamics were realized as a result of increase in end-diastolic and end-systolic volumes of both ventricles together with changes in amplitude and time characteristics of processes of ventricular ejection and filling. Forecast of the probable course of the condition may rely upon the functional state of right as well as left ventricle of the heart.
