Although the short-chain dehydrogenase/reductase (SDR) superfamily contains a very large number of members defined in annotated databases and by biochemical and structural studies, very few SDR enzymes have been identified that have a homologous partner catalyzing the same reaction but with an opposite stereospecificity. In the present study we have cloned and expressed one of these enzymes, th...

INTRODUCTION Hemangiopericytoma (HPC) is an unusual perivascular tumor and first case was described by Stout and Murray in 1942 (1). Moreover, it is classified as a soft-tissue vascular tumor originating from pericytes, which occurs commonly in the extremities, pelvis, head and neck, and meninges (2,3). On the other hand, HPC is rarely encountered in urogenital system (4-6). Renal HPC is also e...

The possibility of preparation of hydrogenated phosphatidylcholine (HPC) liposome precursors (LP) using supercritical anti-solvent technology (SAS) was evaluated. Vitamin D (VD) and coenzyme Q10 (CoQ10) were chosen as the model drugs, and HPC was used as the wall material. The influences of operation conditions (pressures, concentrations and etc.) on the HPC were studied. The structure of the L...

This paper 1 describes a preliminary design of the High-Performance C (HPC) language 2]. HPC, a machine-independent language extension to C, allows the user to write programs for distributed-memory systems using global addresses. HPC includes high-level features for specifying processor arrays and both static and dynamic data distributions across processors and for formulating explicitly loops ...

Networks are the backbone of modern HPC systems. They serve as critical infrastructure, tying together applications, analytics, storage and visualization. Despite this importance, we have not fully explored how evolving communication paradigms and network design will impact scientific workloads. As networks expand in the race towards Exascale, a principled approach should be taken to reexamine ...

In the title coordination polymer, {[Eu(C(7)H(2)NO(5))(H(2)O)(3)]·H(2)O}(n), the Eu(III) atom is eight-coordinated by a tridentate 4-oxidopyridine-2,6-dicarboxyl-ate (hpc) trianion, two monodentate hpc anions and three water mol-ecules, forming a distorted bicapped trigonal-prismatic coordination geometry. The hpc ligands bridge adjacent Eu(III) ions, forming infinite double chains. Adjacent ch...

Flow simulation is a computational tool for exploring science and technology involving flow applications. It can provide cost-effective alternatives or complements to laboratory experiments, field tests and prototyping. Flow simulation relies heavily on high performance computing (HPC). We view HPC as having two major components. One is advanced algorithms capable of accurately simulating compl...

Hippocampal (HPC) theta oscillations have long been linked to various functions of the brain. Many cortical and subcortical areas that also exhibit theta oscillations have been linked to functional circuits with the hippocampus on the basis of coupled activities at theta frequencies. We examine, in freely moving rats, the characteristics of diencephalic theta local field potentials (LFPs) recor...

Intracranial hemangiopericytomas (HPCs) are rare tumors and their radiological appearance resembles that of meningiomas, especially meningothelial meningiomas. To increase the knowledge on the biochemical composition of this type of tumor for better diagnosis and prognosis, we performed a molecular study using ex vivo high resolution magic angle s...

Virtualization has become increasingly popular for enabling full system isolation, load balancing, and hardware multiplexing. This wide-spread use is the result of novel techniques such as paravirtualization that make virtualization systems practical and efficient. Paravirtualizing systems export an interface that is slightly different from the underlying hardware but that significantly streaml...
