The mechanisms behind protein PEGylation are complex and dictated by the structure of the protein reactant. Hence, it is difficult to design a reaction process which can produce the desired PEGylated form at high yield. Likewise, efficient purification processes following protein PEGylation must be constructed on an ad hoc basis for each product. The retention and binding mechanisms driving ele...

Much of what is known about the function of human rostrolateral prefrontal cortex (RLPFC; lateral Brodmann area 10) has been pieced together from functional magnetic resonance imaging (fMRI) studies over the past decade. Christoff and colleagues previously reported on an fMRI localizer task involving relational integration that reliably engages RLPFC in individual participants (Smith, R., Keram...

The tadpole shrimp (Triops longicaudatus) is an aquatic crustacean that helps control pest populations. It inhabits freshwater ponds and pools and has been described as a living fossil. T. longicaudatus was officially declared an endangered species South Korea in 2005; however, through subsequent protection and conservation management, it was removed from the endangered species list in 2012. Th...

The renin-angiotensin system (RAS) has emerged as one of the essential links in the pathophysiology of vascular disease. Angiotensin (Ang) II, the main peptide of the RAS, was considered as a vasoactive hormone, but in the past years, this view has been modified to a growth factor that regulates cell proliferation/apoptosis and fibrosis. Recently, this view has been enlarged with a novel concep...

Finding underlying relationships among multiple imaging modalities in a coherent fashion is one of the challenging problems in multimodal analysis. In this study, we propose a novel approach based on multidimensional persistence. In the extension of the previous threshold-free method of persistent homology, we visualize and discriminate the topological change of integrated brain networks by var...

Using data from 1387 lakes collected over three decades, we found a wide range in the concentrations of total phosphorus (TP), total nitrogen (TN) and chlorophyll in Florida lakes, and that edaphic factors as outlined by the USEPA’s Florida Lake Regions were the dominant factor in determining the concentrations of plant nutrients in the state’s lakes. The hypothesis that all eutrophic lakes in ...

Investigator-initiated trials (IIT) are important aspects of medical research and have contributed substantially to modern oncology. IIT using post-approval drugs have been conducted by domestic institutions in Japan. Data from the present study were obtained by all IIT registered clinical trials for five cancers (lung, colorectal cancer, gastric cancer, liver cancer, and breast cancer) using d...

Federated cloud systems increase the reliability and reduce the cost of computational support to an organization. The resulting combination of secure private clouds and less secure public clouds impacts on the security requirements of the system. To meet these security requirements, applications need to be located within different clouds, which strongly affects the information flow security of ...

OBJECTIVE Treatment strategies for post-stroke spasticity include oral anti-spastic drugs, surgery, physiotherapy and botulinum toxin type A injection. The objective of this study was to compare the cost-effectiveness and outcomes of oral therapy vs. botulinum toxin type A treatment strategies in patients with flexed wrist/clenched fist spasticity. METHODS Treatment outcome and resource use d...

INTRODUCTION Deep vein thrombosis (DVT) is a major cause of morbidity and mortality in intensive care unit (ICU) patients despite use of prophylactic anticoagulant therapy. The aim of the present study was to determine the incidence of DVT among medical and surgical ICU patients. METHODS In this cross sectional study, patients older than 18 years who were hospitalized in the ICU of Imam Hosse...
