Lexical and morphological knowledge of school-aged children are correlated with each other, and are often difficult to distinguish. One reason for this might be that many tasks currently used to assess morphological knowledge require children to inflect or derive real words in the language, thus recruiting their vocabulary knowledge. The current study investigated the possible separability of l...

Contractile tissues demonstrate a pronounced capacity to remodel their composition in response to mechanical challenges. Descriptive evidence suggests the upstream involvement of the phosphotransfer enzyme FAK (focal adhesion kinase) in the molecular control of load-dependent muscle plasticity. Thereby FAK evolves as a myocellular transducer of mechanical signals towards downstream transcript e...

Patients with a tuberculoma typically present with pulmonary involvement of tuberculosis and have risk factors for tuberculosis (TB). The risk factors for tuberculosis include bacillary load, proximity to infectious case, immunosuppressive conditions, malnutrition, young age, diabetes mellitus, working in healthcare, recent incarceration, alcohol use, and tobacco use. Although rare, it is possi...

manual patient handling is known to be the major source of musculoskeletal load among hospital nurses. the objectives of the present study were determination of frequency of musculoskeletal disorders (msds) and its associated factors together with assessment of musculoskeletal load due to patient transfer by ptai method in hospital nursing staff of shiraz university of medical sciences (sums), ...

Early neuropathological changes characteristic of late-onset Alzheimer's disease (LOAD) involve brain stem and limbic structures that regulate neurovegetative functions, including sleep-wake rhythm. Indeed, sleep pattern is an emerging biomarker and a potential pathophysiological mechanism in LOAD. We hypothesized that cognitively asymptomatic, middle-aged offspring of patients with LOAD (O-LOA...

Previous research reveals that older adults sometimes show enhanced processing of emotionally positive stimuli relative to negative stimuli, but that this positivity bias reverses to become a negativity bias when cognitive control resources are less available. In this study, we test the hypothesis that emotionally positive feedback will attenuate well-established age-related deficits in rule le...

Humans can program and control movements, including breathing-related movements. On the electroencephalogram (EEG), this preparation is accompanied by a low-amplitude negativity starting approximately 2.5 s before inspiration that is best known as a Bereitschaftspotential (BP). The presence of BPs has been described during the compensation of mechanical inspiratory loading, thus identifying a c...

This paper reports a study which investigated if there was a match between students’ English vocabulary size and the vocabulary load of a locally produced textbook. The analysis of the passages of the pre-university English textbook currently in use in Iran’s education system using RANGE program indicated that in order to comprehend the texts, students need to know not only words from 2000 high...

background the immune system plays important roles in determining the outcomes of hepatitis c virus (hcv) infection. interleukin-23 and -27 (il-23 and il-27) are two novel il-12 cytokine family members known to enhance the t-lymphocyte response, but their precise involvement in hcv infection is not well known. objectives we investigated the serum il-27 and il-23 levels in patients with hcv infe...
