Speech Facilitates the Categorization of Motions in 9-Month-Old Infants.

Two experiments were used to investigate the influence of both native and non-native speech on the categorization of a set of an object's motions by 9-month-olds. In Experiment 1, infants were habituated to a set of three object motions and tested with familiar and novel motions. Results of Experiment 1 show that infants were more likely to categorize the motion stimuli if they listened to either the native or non-native speech during the categorization process than if they listened to music or heard nothing at all.

Comparative innate immune interactions of human and bovine secretory IgA with pathogenic and non-pathogenic bacteria.

Secretory IgA (SIgA) from milk contributes to early colonization and maintenance of commensal/symbiotic bacteria in the gut, as well as providing defence against pathogens. SIgA binds bacteria using specific antigenic sites or non-specifically via its glycans attached to α-heavy-chain and secretory component. In our study, we tested the hypothesis that human and bovine SIgA have similar innate-binding activity for bacteria.

Systolic blood pressure does not reliably identify vasoactive status in chronic heart failure.

Background: In chronic heart failure (CHF), titration of vasodilating medications is often guided by monitoring of systolic blood pressure (BP). However, systolic BP may not indicate the patient's true vasoactive status-best approximated by systemic vascular resistance-because cardiac output is also a contributing factor. Impedance cardiography (ICG) is a validated noninvasive method of measuring cardiac output and systemic vascular resistance.

Studies of Ion Kinetic-Energy Distributions in the Gaseous Electronics Conference RF Reference Cell.

A review is presented of kinetic-energy distribution measurements for ions striking grounded surfaces in a Gaseous Electronics Conference (GEC) rf Reference Cell. Two experimental arrangements that have been used to measure ion energies in the GEC Cell are described, and a comparison of their performance under different operating conditions is presented. Significant results from ion-energy analysis in the Reference Cell are highlighted, including evidence of effects due to surface conditions on ion sampling, verification of electrical behavior of the cell, inferences about ion-molecule reactions indicated by the shapes of measured ion kinetic-energy distributions (IEDs), and the use of measured IEDs for the validation of theoretical models.

System for Measuring Conditional Amplitude, Phase, or Time Distributions of Pulsating Phenomena.

A detailed description is given of an electronic stochastic analyzer for use with direct "real-time" measurements of the conditional distributions needed for a complete stochastic characterization of pulsating phenomena that can be represented as random point processes. The measurement system described here is designed to reveal and quantify effects of pulse-to-pulse or phase-to-phase memory propagation. The unraveling of memory effects is required so that the physical basis for observed statistical properties of pulsating phenomena can be understood.

Isoform patterns of apolipoprotein E in diabetes mellitus.

Apolipoproteins in delipidated VLDL preparations from normal, diabetic, and non-diabetic hyperlipidaemic subjects were analysed by SDS-polyacrylamide gel electrophoresis, and by isoelectric focusing. On electrophoresis, diabetic VLDL contained more apolipoprotein E (17.3 +/- 7.

The effect of calcium antagonists on the activities of lipid metabolizing enzymes in the isolated ischaemically perfused and reperfused rat heart.

Isolated rat hearts were perfused with various external Ca2+ concentrations and with various Ca2+ uptake antagonists. Compared to control activities (at 1.2 mM Ca2+), 0.

Identification of ADPR-transferase activity in the rat tapeworm, Hymenolepis diminuta.

1. The nuclear fraction of the rat tapeworm Hymenolepis diminuta (Cestoda) contains the enzyme adenosine diphosphoribosyl transferase (ADPR-transferase). 2.

The effect of coronary artery occlusion and reperfusion on the activities of triglyceride lipase and glycerol 3-phosphate acyl transferase in the isolated perfused rat heart.

Glycerol 3-phosphate acyltransferase (GPAT) and Triglyceride lipase (TGL) were measured in homogenates from non-ischaemic and ischaemic tissue from the isolated perfused rat heart. Ischaemia was produced by occlusion of the left descending coronary artery for 10 min. Compared to activities measured in tissue from normally perfused hearts, GPAT activity measured in tissue from the ischaemic area was considerably reduced.

The effect of adrenergic agents on the activities of glycerol 3-phosphate acyltransferase and triglyceride lipase in the isolated perfused rat heart.

Glycerol 3-phosphate acyltransferase (GPAT) activity and triglyceride lipase (TGL) activity were measured in homogenates from hearts perfused with adrenergic agonists and antagonists. Perfusion with adrenalin or the beta-agonist isoprenaline produced an increase in TGL activity and a fall in GPAT activity. These changes could be imitated by incubation of heart homogenates with cAMP-dependent protein kinase.

Production Rates for Oxyfluorides SOF, SOF, and SOF in SF Corona Discharges.

The most abundant, long-lived stable gaseous species generated by corona discharges in SF gas containing trace levels of O and HO are the oxyfluorides SOF, SOF, and SOF. Absolute energy and charge rates-of-production of these and the minor products SO, OCS, and CO have been measured at different total gas pressures from 100 kPa to 300 kPa and for discharges of different current, power, and polarity. Oxyfluoride yields for SF/O mixtures containing up to 10% O have also been measured.

Stimulus intensity, catch trial effects, and the speed-accuracy tradeoff in reaction time: A variable criterion theory interptation.

Ss responded to a 1,000-Hz tone of 50, 80, or 100 dB. Catch trial conditions were none, blank trials, a red light, a noise, and an 1,800-Hz tone. Auditory catch signals were of the same intensities.
