OBJECTIVE To determine whether the extent of surgery is associated with survival in anorectal malignant melanoma (ARMM). BACKGROUND ARMM is a rare and highly malignant neoplasm with unfavorable prognosis. The optimal surgical management, abdominoperineal resection (APR) or local excision (LE), has been long debated, but conclusive evidence has not been obtained. METHODS A comprehensive elec...

Aqueous phase reforming (APR) of biomass derived feedstock producing hydrogen was reviewed. The APR process was discussed based on different feedstock categories such as sugars, polyols and ethanol. The mechanism of APR was analyzed referring to different structures of feedstock. The reaction pathways of APR were investigated. The usage of catalysts should be judged by feedstock on the requirem...

OBJECTIVE To evaluate the performance of APR-DRG (All Patient Refined-Diagnosis Related Group) Risk of Mortality (ROM) score as a mortality risk adjustor in the intensive care unit (ICU). DESIGN Retrospective analysis of hospital mortality. SETTING Medical ICU in a university hospital located in metropolitan New York. PATIENTS 1213 patients admitted between February 2004 and March 2006. ...

This paper describes the evolution of Assistant Personal Robot (APR) project developed at Robotics Laboratory University Lleida, Spain. first APR-01 prototype developed, basic hardware improvement, specific anthropomorphic improvements, and preference surveys conducted with engineering students from same university in order to maximize perceived affinity final APR-02 mobile robot prototype. The...

In this paper, we introduce the notion of soft (apr P , aprP ) (resp, (Apr P , aprP ), (aprP , AprP ), (AprP , AprP )) rough approximations. Mathematics Subject Classification: 08A05, 54A05, 94A15

BACKGROUND Understanding co-morbidity of depression and tuberculosis (TB) has been limited by challenges in measurement of depression due to overlapping symptoms, use of small hospital samples and uncontrolled analysis. This study was conducted to better understand the burden and presentation of depression, and associated factors in people with TB in primary care settings in Ethiopia. METHODS...

BACKGROUND Bladder exstrophy (BE) and cloacal exstrophy (CE) are rare birth defects that have been reported to occur in 1:30,000-50,000 and 1:200,000-400,000 live births. Disagreement exists as to whether they comprise two distinct disorders or are part of a spectrum. We examined epidemiologic trends and risk factors for BE and CE in a large population-based dataset. METHODS Potential cases w...
