A concise outline of background is given on assistive methods for writing and communicating for non-speaking people, highlighting the role of efficient text entry in augmentative and alternative communication (AAC). AAC systems are designed to assist people with communication impairments to interact with others and to compose messages and other documents. Efficient text entry is therefore of gr...

Objective: Visible aortic arch calcification (AAC) on chest radiographs is putatively associated with cardiovascular outcomes. This retrospective study investigated a correlation between the semi-quantitative extent of AAC and cardiovascular disease severity. Methods: 305 consecutive patients presenting with chest pain who underwent coronary artery angiography and chest radiography during the s...

BACKGROUND Augmentative and alternative communication (AAC) interventions are used for children with autism, often as stand-alone communication interventions for those who are minimally verbal. Our aim was to synthesize the evidence for AAC interventions for children (up to 21 years), and then consider the role of AAC within established, comprehensive, evidence-based autism interventions target...

(AAC), it is particularly difficult to satisfy the diversity of AAC user requirements because individual user characteristics (e.g., abilities, skills, requirements, and preferences) may vary significantly. In principle, each AAC user may require a communication device specifically tailored to his or her particular needs. Technological advancements have led to the development of a wide variety ...

OBJECTIVES The Acuity Adaptable Patient Care (AAC) unit system allows all beds within a nursing unit to negate the need for transfer with changes in patient status. The unit is specialty specific to all levels of patient care. This system was implemented in March 2006 for cardiothoracic surgery at our institution. The purpose of this study was to evaluate the impact of the AAC system on the out...

This study examines linguistic co-occurrence patterns in the discourse of individuals with communication impairments who use augmentative and alternative communication (AAC) devices in the workplace by comparing them to those of non-AAC users in similar job settings. A typical workweek (≈ 40 hours) per focal participant (four AAC; four non-AAC) was recorded and transcribed to create a specializ...

The nuclear factor Acinus has been suggested to mediate apoptotic chromatin condensation after caspase cleavage. However, this role has been challenged by recent observations suggesting a contribution of Acinus in apoptotic internucleosomal DNA cleavage. We report here that AAC-11, a survival protein whose expression prevents apoptosis that occurs on deprivation of growth factors, physiological...

The ADP/ATP carrier (AAC) that facilitates the translocation of ATP made in mitochondria is inserted at the inner mitochondrial membrane by the TIM10-TIM22 protein import system. Here we addressed the state of the AAC precursor during insertion (stage IV of import) and identified residues of the carrier important for dimerization. By a combination of (i) import of a mix of His-tagged and untagg...

BACKGROUND Abdominal aortic calcification (AAC) is a marker of subclinical atherosclerotic disease and an independent predictor of subsequent vascular morbidity and mortality. This study was conducted to investigate the association of AAC with lifestyle and risk factors of cardiovascular disease. METHODS The results of the abdominal computed tomography of 380 patients who visited Chungnam Nat...

The iPad and other mobile technologies provide powerful new tools to potentially enhance communication for individuals with developmental disabilities, acquired neurogenic disorders, and degenerative neurological conditions. These mobile technologies offer a number of potential benefits, including: (a) increased awareness and social acceptance of augmentative and alternative communication (AAC)...
