Knowledge, Attitude and Behavioral Intention about Cancer of Oral Cavity and Pharynx among Public Health Students in Southeast Georgia
<p>Oral cancer is a significant public health problem; however, there is lack of awareness at community level regarding oral cancer. Considering the importance of public health education, which educates people regarding prevention of disease and promotion of health, public health professionals can …

A link between c. Elegans morphogenesis and mrna export
… development of the Caenorhabditis elegans pharynx. In this study we used whole genome sequencing (WGS) and CloudMap/Hawaiian Variant Mapping to specifically map a mutation that produced a Pun pharynx (unattached pharynx) phenotype. We discovered a thermo-sensitive t2160 mutant allele of …

Molecular, cellular, and circuit analysis of C. elegans spitting behavior
… simple system for such behavioral studies is the pharynx of the nematode worm C. elegans, which contracts rhythmically (pumps) to ingest food. The connectivity (connectome) of the 20 pharyngeal neurons has been completely determined, making the pharynx one of the anatomically simplest and …

Heme Peroxidase Hpx-2 Protects Caenorhabditis Elegans From Pathogens
… labeling of HPX-2 revealed its expression in the pharynx, an organ in which BLI-3 also resides. Interestingly, loss of HPX-2 increased intestinal colonization of <em>E. faecalis, </em>suggesting its role in the pharynx may limit intestinal colonization. Moreover, disruption of a catalytic residue …

Magnetic Resonance Imaging of the Levator Veli Palatini Muscle During Speech and Swallowing
… a functional biomechanical model of the human pharynx. Such models will be useful in the development of therapy protocols and to assist surgeons in the plan for reconstructive surgery.

Epidemic influenza: its causation and prevention
… discharge from the epithelium of the nose, pharynx, and bronchial tree. Economically it is important, as twenty per cent or more of a given population may be affected by it; taking to bed for about four days and remaining "off-colour" for two or three weeks thereafter.

Studies on the development of the upper air passages
… of the development of the nose, mouth, and pharynx. The methods of research employed in this piece of work have been mainly the use of wax plate reconstructions, while some embryos have been examined by the microscope alone. However, as the number of human embryos available was very limited, …

Comparative anatomy and evolution of the gastrotrich muscular system
… muscles in 50--60° angles are present on the pharynx and intestine of most species. Longitudinal muscles are arranged radially around the digestive tract in dorsal, lateral, ventral and ventrolateral positions. Extraordinary muscle orientations are present in several species.</p><p>In …

Identifizierung und Charakterisierung von AST-1 in C. elegans, einem ETS Transkriptionsfaktor, der die axonale Wegfindung reguliert
… Defekten noch späte Differenzierungsdefekte des Pharynx. Ast-1 kodiert für einen Transkriptionsfaktor mit einer ETS DNS-Bindedomäne und ist eng mit der Fli-1 Unterfamilie in Säugetieren verwandt. Ast-1::YFP Expression begann während der Embryonalentwicklung in sensorischen Neuronen und …

An investigation into the mode of action of the anthelmintic emodepside: a molecular, pharmacological and electrophysiological characterisation
… reduces the sensitivity of the C. elegans pharynx to emodepside (Willson et al 2004). Targeting of either lat-1 or lat-2 by RNA interference reduced the sensitivity of C. elegans to emodepside’s effects on locomotion. Simultaneous targeting of lat-1 and lat-2 by RNA interference reduced the …

Pathological study of the pathways of infection to the intracranial structures from foci of inflammation on the face and in the nasal and nasal accessory cavities
… foci in the nose, nasal accessory sinuses, and pharynx, the writer was much impressed by the fact that in almost every case published in which the author had mentioned the pathway by which the infection had passed from the peripheral focus to within the cranium, the lymphatic system either was …

Complicaciones respiratorias en pacientes intervenidos por cáncer de cavidad oral, faringe y laringe en La Rioja
… thesis focuses on tumors of the oral cavity, pharynx, and larynx, as sinonasal and nasopharyngeal tumors have different epidemiological, pathological, and therapeutic characteristics. Recently, a decrease in laryngeal cancers and an increase in oral cavity and oropharyngeal cancers have been …

A size and shape analysis in obstructive sleep apnea patients
… Results from the PLS analysis confirmed that the pharynx variables obtained in the upright position may best predict symptom severity. Overall, the new morphometric tools adopted here were found to be viable inOSA analysis.
