Th17 and Th1 play an important role in multiple sclerosis for which copolymer I (COP-I) is a treatment option. We described here that the treatment effect of COP-I correlated with its unique regulatory properties on differentiation and survival of Th17 in experimental autoimmune encephalomyelitis mice, which was mediated through down-regulation of STAT3 phosphorylation. The effect of COP-I on T...

[Purpose] This study aimed to investigate the postural control characteristics of individuals with and without a history of ankle sprain during single-leg standing by examining the relationship between various parameters of center of pressure (COP) and head and foot acceleration. [Subjects] Twenty subjects with and 23 subjects without a history of ankle sprain (sprain and control groups, respec...

Cytoplasmic dilysine motifs on transmembrane proteins are captured by coatomer α-COP and β'-COP subunits and packaged into COPI-coated vesicles for Golgi-to-ER retrieval. Numerous ER/Golgi proteins contain K(x)Kxx motifs, but the rules for their recognition are unclear. We present crystal structures of α-COP and β'-COP bound to a series of naturally occurring retrieval motifs-encompassing KKxx,...

BACKGROUND Non-small cell lung cancer is associated with high expression of multidrug resistance (MDR) proteins and low production of reactive oxygen species (ROS). Coptis extract (COP), a Chinese medicinal herb, and its major constituent, berberine (BER), have anticancer properties. This study aims to investigate the effects of COP and BER combined with chemotherapeutic agents, including fluor...

The cardiohemodynamic effects of nipradilol (K-351) were studied in comparison with those of propranolol, nadolol and prazosin in anesthetized, open-chest dogs. All drugs were administered intravenously. Nipradilol produced dose-dependent decreases in systemic blood pressure (BP), heart rate (HR), venous return (VR) and cardiac output (COP), but virtually no change in right atrial pressure (RAP...

Copolymer-I (COP-I) has unique immune regulatory properties and is a treatment option for multiple sclerosis (MS). This study revealed that COP-I induced the conversion of peripheral CD4+CD25- to CD4+CD25+ regulatory T cells through the activation of transcription factor Foxp3. COP-I treatment led to a significant increase in Foxp3 expression in CD4+ T cells in MS patients whose Foxp3 expressio...

Center of pressure (COP) trajectories summarize the complex mechanical interaction between the foot and a contacted surface. Each trajectory itself is also complex, comprising hundreds of instantaneous vectors over the duration of stance phase. To simplify statistical analysis often a small number of scalars are extracted from each COP trajectory. The purpose of this paper was to demonstrate ho...

CoP nanostructures that exposed predominantly (111) crystal facets were synthesized and evaluated for performance as electrocatalysts for the hydrogen-evolution reaction (HER). The branched CoP nanostructures were synthesized by reacting cobalt(II) acetylacetonate with trioctylphosphine in the presence of trioctylphosphine oxide. Electrodes comprised of the branched CoP nanostructures deposited...

In this article, a stepwise procedure, correlation pursuit (COP), is developed for variable selection under the sufficient dimension reduction framework, in which the response variable Y is influenced by the predictors X(1), X(2), …, X(p) through an unknown function of a few linear combinations of them. Unlike linear stepwise regression, COP does not impose a special form of relationship (such ...

Background. Idiopathic Pulmonary Fibrosis (IPF) is a fatal lung disease of unknown etiology characterized by interstitial fibrosis determining irreversible distortion of pulmonary architecture. Reactive oxygen species (ROS) and markers of oxidative stress play a pivotal role in human IPF pathology, possibly through induction of epithelial-mesenchymal transition (EMT). Methods. We investigated b...
