Hepatic epithelioid hemangioendothelioma (HEH) is an unusual, low-grade malignant vascular tumor of the liver. Here we describe a case of a 40-year-old woman who presented with abdominal pain in the upper right quadrant and giant hepatomegaly, in which imaging studies and a fine-needle liver biopsy confirmed the presence of a large EHE with an isolated lung metastasis. After balancing all possi...

December 1, 2009, marks the tenth anniversary of the Institute of Medicine report on medical errors, To Err Is Human, which arguably launched the modern patient-safety movement. Over the past decade, a variety of pressures (such as more robust accreditation standards and increasing error-reporting requirements) have created a stronger business case for hospitals to focus on patient safety. Rela...

Contemporary Grid environments are featured by an increasingly growing virtualization and distribution of resources. Such situations impose greater demands on load-balancing and fault-tolerant capabilities. The checkpointrestart mechanism seems to be the most intuitive tool that can fulfill the specific requirements. However, as there is still a lack of widely available, production-grade checkp...

In recent years, two concepts similar to /?-sequences have appeared, essential sequences and asymptotic sequences. This work explores the general nature of such sequences. Introduction. In the last three years, two concepts similar to that of Ä-sequences have appeared, asymptotic sequences and essential sequences. Motivated by these examples, this paper will study the general nature of such seq...

background and aims: p504s (amacr) is a mitochondrial enzyme expressed in renal cell carcinoma. some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. amacr expression increases with higher histological grading in different tumors; however, in rcc it is not obvious. in this study, we tried to investigate if any relat...

In order to reduce the unbalance vibration of the rotating machinery automatically during the work process, a new type of liquid-transfer active balancing system was proposed. In the system, a balancing disc divided into four liquid storage chambers was mounted on the rotor. When the unbalance response of the rotating machinery was higher than the limiting value, compressed air was injected to ...
