Most clinicians agree that impaired nasal breathing results in obligatory mouth breathing. Some believe that mouth breathing influences dentofacial growth; others disagree. The term mouth breathing is confusing because total mouth breathing rarely occurs. A combination of nasal and oral breathing is more usual. The purpose of the present study involving 116 adult subjects was to (1) assess the ...

The method of constant stimuli was used to examine the accuracy with which two-dimensional spatial information can be represented in mental images. In experiment 1, subjects had to decide which of two successively presented two-dot separations was wider. Over the range of interstimulus intervals employed (0 to 30s), there was a linear relationship between interstimulus interval and spatial inte...

The article concerns potential harmful effects of exposure to lead. Although the occurrence of severe lead poisoning has receded in several countries, occupational exposure resulting in moderate and clinically symptomatic toxicity is still common. An earlier and precise characterization of an individual response is obligatory in order to assess the possible risks for human health. Biomarkers ma...

Plasma atrial natriuretic peptide concentrations were measured by radioimmunoassay six to 77 weeks after operation in eight cardiac transplant recipients with no appreciable evidence of cardiac failure or rejection and in eight control subjects matched for age, sex, race, and blood pressure. Plasma atrial natriuretic peptide concentrations were significantly higher in the cardiac transplant rec...

1 Fact and Fiction in Icelandic Control Jonathan David Bobaljik and Idan Landau Abstract A rich literature on Icelandic syntax has established that infinitival complements of obligatory control (OC) verbs constitute a case assignment domain independent from the matrix clause, and in this differ systematically from all types of A-movement, which manifest case dependence/preservation. As Landau (...

Selective auditory attention powerfully modulates neural activity in the human auditory cortex (AC). In contrast, the role of attention in subcortical auditory processing is not well established. Here, we used functional MRI (fMRI) to examine activation of the human inferior colliculus (IC) during strictly controlled auditory attention tasks. The IC is an obligatory midbrain nucleus of the asce...

The left inferior frontal gyrus (LIFG) has long been claimed to play a key role in language function. However, there is considerable controversy as to whether regions within LIFG have specific linguistic or domain-general functions. Using fMRI, we contrasted linguistic and task-related effects by presenting simple and morphologically complex words while subjects performed a lexical decision (LD...

A pragmatic emotional model is one of obligatory subjects for building a humanoid computer. This paper presents a conception of a Mental State Transition Network Model using psychological research for reference [1]. The ongoing work proposes a novel approach to detect human emotions. According to Pluchik’s basic emotional classification, we defined nine basic emotional states and carried out a ...

Primary drug resistance is an emerging problem in HIV infections. We have investigated the current prevalence of primary resistance in Korea and compared it with previous data. Drug-naive HIV patients attending the outpatient clinic of Seoul National University Hospital between April and August 2006 were enrolled. A medical interview and a genotypic resistance test were performed for each patie...

[Purpose] The fluid goniometer is an instrument for measuring range of motion. Reliability of the fluid goniometer has not been established for subjects with painful knee joints. The purpose of this study was to determine the inter-rater and intra-rater reliability of the fluid goniometer in measuring active knee flexion of painful knees and to test its agreement with the gold standard ruler go...
