Limited research exists on how speech impairments affect quality of life (QOL) factors over time in patients with amyotrophic lateral sclerosis (ALS). A review of the literature, including the history, disease course, and prevalence of ALS, is presented. Physical and psychosocial functioning, especially the decline of bulbar functioning’s potential impact on QOL factors and communication style,...

This project aims to overcome the access barriers to virtual worlds for motorand speech-impaired users by building a gaze-controlled interface for Second Life that will enable them to interact with the virtual world by just moving their eyes. We have conducted a study to assess (1) the facilitation of gaze-controlled text input using word prediction technique to speed up chatstyle text input in...

Case description: A 20-year-old male patient presented for routine dental treatment. By radiographic examination we noted an extensive radioluscent area, laterally to the permanent maxillary right lateral incisor, with possibility of communication with the lateral periodontium, suggestive of a chronic apical periodontitis. Due to external root resorption detection, we used a calcium hydroxide r...

The effect of lateral pressure on the wavelength response characteristics of a fiber Bragg grating embedded in a cylindrical package of silicone rubber has been investigated in this report. Due to high Poisson’s ratio (0.48) and low stiffness of silicone rubber, force applied in one direction will be efficiently transferred to the perpendicular direction also. A wavelength shift of more than 1 ...

Lateral roots are formed postembryonically and determine the final shape of the root system, a determinant of the plants ability to uptake nutrients and water. The lateral root primordia are initiated deep into the main root and to protrude out the primary root they have to grow through three cell layers. Recent findings have revealed that these layers are not merely a passive physical obstacle...

INTRODUCTION Cleft lip and palate are craniofacial anomalies highly prevalent in the overall population. In oral clefts involving the alveolar ridge, variations of number, shape, size and position are observed in maxillary lateral incisors. The objective of this manuscript is to elucidate the embryonic origin of maxillary lateral incisors in order to understand the etiology of these variations....

Pheromones play major roles in intraspecific communication in many animals. Elaborated communication systems in eusocial insects provide excellent materials to study neural mechanisms for social pheromone processing. We previously reported that alarm pheromone information is processed in a specific cluster of glomeruli in the antennal lobe of the ant Camponotus obscuripes. However, representati...

Distinct domains of the prefrontal cortex in primates have a set of connections suggesting that they have different roles in cognition, memory, and emotion. Caudal lateral prefrontal areas (areas 8 and 46) receive projections from cortices representing early stages in visual or auditory processing, and from intraparietal and posterior cingulate areas associated with oculomotor guidance and atte...
