Autophagy is an evolutionarily conserved intracellular catabolic system for degradation of long-lived proteins or damaged organelles. In this study, we have identified and characterized a new gene, epg-1, that plays a role in the autophagy pathway in C. elegans. Loss of function of epg-1 causes defects in various autophagy-regulated processes, including degradation of aggregate-prone proteins a...

Electropalatography (EPG) has become relatively well established as a safe and convenient technique for use in the assessment, diagnosis and treatment of children and adults with articulation disorders. EPG's wide applicability is reflected in the range of different cases that has been researched in recent years. Some research has been carried out using EPG therapy for deaf individuals who use ...

Knowledge of horses that shed the same number of strongyle eggs over time can lead to the optimization of parasite control strategies. This study evaluated shedding of strongyle eggs in 424 horses on 10 farms when a selective anthelmintic treatment regime was used over a 3-year period. Faecal egg counts were performed twice yearly, and horses exceeding 200 eggs per gram (EPG) of faeces were tre...

Four ErbB receptors and multiple growth factors sharing an epidermal growth factor (EGF) motif underlie transmembrane signaling by the ErbB family in development and cancer. Unlike other ErbB proteins, ErbB-2 binds no known EGF-like ligand. To address the existence of a direct ligand for ErbB-2, we applied algorithms based on genomic and cDNA structures to search sequence data bases. These sear...

OBJECTIVE This study investigated the influence of a standard electropalatography (EPG) palate upon speech articulation in 3 normal speakers under standard EPG testing conditions. PATIENTS AND METHODS Three adult females aged 26, 31 and 34 years read the experimental phrase 'say CV again' 5 times under 3 experimental conditions: normal speech (without a palate in situ), 45 min after EPG palat...

A cross-sectional survey was undertaken in children aged 9-14 years in Beyla and Macenta Prefectures, Forest Guinea. Stool samples were examined by Kato-Katz and urine samples were examined by the centrifugation method. The overall prevalence and intensity of infection was 66.2% and 462.4 eggs per gram of faeces (epg) for Schistosoma mansoni, 21.0% and 17.8 eggs per 10ml of urine for S. haemato...

A newly isolated Galactomyces geotrichum ZJUTZQ200 strain containing an epoxide hydrolase was used to resolve racemic ethyl 3-phenylglycidate (rac-EPG) for producing (2R,3S)-ethyl-3-phenylglycidate ((2R,3S)-EPG). G. geotrichum ZJUTZQ200 was verified to be able to afford high enantioselectivity in whole cell catalyzed synthesis of this chiral phenylglycidate synthon. After the optimization of th...

This paper outlines new developments and recent research in electropalatography (EPG) and discusses how they have contributed to theoretical issues in speech pathology and clinical practice. A central theoretical issue in speech pathology is defining the articulatory processes underlying speech disabilities. EPG data are providing increasing evidence that abnormal speech motor control underlies...

The screening of candidate compounds and natural products for anthelmintic activity is important for discovering new drugs against human and animal parasites. We previously validated in Caenorhabditis elegans a microfluidic device ('chip') that records non-invasively the tiny electrophysiological signals generated by rhythmic contraction (pumping) of the worm's pharynx. These electropharyngeogr...

Autophagy is a catabolic process through which damaged organelles and protein aggregates are delivered to lysosomes for degradation. Autophagy genes are reported to promote exposure of "eat me" signals on the surface of apoptotic cells, but whether they function in engulfing cells is not clear. Recently, we found that the autophagy mutants atg-18 and epg-5 are defective in removing apoptotic ce...
