BACKGROUND AND STUDY AIMS Esophageal squamous papilloma (ESP) is a rare lesion. The aims of this study were to assess the prevalence of ESP in northeastern France and the risk of associated squamous cell carcinoma (SCC). PATIENTS AND METHODS The charts of 78 patients who were diagnosed with ESP between January 2005 and February 2013 at three hospitals in northeastern France were reviewed. R...

The locus of enterocyte effacement (LEE), which includes five major operons (LEE1 through LEE4 and tir), enables enterohemorrhagic Escherichia coli (EHEC) O157:H7 to produce attaching and effacing lesions on host cells. Expression of LEE2, LEE3, and tir is positively regulated by ler, a gene located in LEE1. Transcriptional regulation of the esp operon (LEE4), however, is not well defined. Tran...

ESP can help the road vehicle to improve driving dynamics and prevent accidents which result from loss of control. Based on the theory and account method of Multi-body System Dynamics, the Multi-body System Dynamics model of an A-class car is built by the ADAMS/Car software, which includes steering system, front and rear suspension, braking system, body, and so on. In order to study the handlin...

Chicken eggshell powder (ESP) might be an attractive source of Ca for human nutrition. To study its nutritional value, we analyzed minerals, amino acids, and hormones in commercially available Slovakian ESP. The mineral composition was compared with three Dutch ESP samples that differed in feed and housing, a Japanese ESP, refined CaCO3, and an oyster shell supplement. Chicken eggshell powder c...

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

While several self-indexes for highly repetitive texts exist, developing a practical self-index applicable to real world repetitive texts remains a challenge. ESP-index is a grammar-based self-index on the notion of edit-sensitive parsing (ESP), an efficient parsing algorithm that guarantees upper bounds of parsing discrepancies between different appearances of the same subtexts in a text. Alth...

language and culture are now deemed to be co-constitutive; hence english language teaching (elt) textbooks should incorporate cultural aspects and promote intercultural competence. however, careful decisions should be made as regards to the cultural content of materials and the ways in which culture is represented. this study was an attempt to deconstruct the patterns of cultural representation...

BACKGROUND Strategies employed by parasites to establish infections are poorly understood. The host-parasite interface is maintained through a molecular dialog that, among other roles, protects parasites from host immune responses. Parasite excretory/secretory products (ESP) play major roles in this process. Understanding the biology of protein secretion by parasites and their associated functi...

Investigators have pondered whether or not ESP size has an impact on mercury capture by sorbent injection or deposition on fly ash. If important, ESP size would then have an impact on how effectively a power plant captures mercury and can comply with mercury control requirements. There are two possible elements to the impact of ESP size. First, does a larger ESP enable more mercury capture to o...
