IK acts as an immunoregulator of inflammatory arthritis by suppressing T17 cell differentiation and macrophage activation.

Pathogenic T helper cells (T) and macrophages have been implicated in the development of rheumatoid arthritis (RA), which can lead to severe synovial inflammation and bone destruction. A range of therapies have been widely used for RA, including specific monoclonal antibodies and chemical inhibitors against inflammatory cytokines produced by these cells. However, these have not been sufficient to meet the medical need.

Tracking Study About Adenovirus 36 Infection: Increase of Adiposity.

This study investigated the cross-sectional and longitudinal association between adenovirus 36 (Ad36) and obesity in 79 Korean adolescent boys over 1 year. We analyzed the changes in body composition and metabolic risk factors according to the presence of Ad36 antibodies. Ad36 antibodies in serum were detected using the constant virus-decreasing serum method.

Adenovirus 36 attenuates weight loss from exercise but improves glycemic control by increasing mitochondrial activity in the liver.

Human adenovirus type 36 (Ad36) as an obesity agent induces adiposity by increasing glucose uptake and promoting chronic inflammation in fat tissues; in contrast, exercise reduces total body fat and inflammation. Our objective was to determine the association between Ad36 and the effects of exercise on inflammation and glycemic control. In the human trials (n = 54), Korean children (aged 12-14 years) exercised for 60 min on three occasions each week for 2 months.

Obesity-induced chronic inflammation is associated with the reduced efficacy of influenza vaccine.

The relationship between obesity and vaccine efficacy is a serious issue. Previous studies have shown that vaccine efficacy is lower in the obese than in the non-obese. Here, we examined the influence of obesity on the efficacy of influenza vaccination using high fat diet (HFD) and regular fat diet (RFD) mice that were immunized with 2 types of influenza virus vaccines-cell culture-based vaccines and egg-based vaccines.

Reduction of adenovirus 36-induced obesity and inflammation by mulberry extract.

Adenovirus 36 (Ad36) is known to be associated with human obesity and to trigger inflammation in murine models. However, to date no clinical drugs for treating virus-induced obesity have been developed. Therefore, in this study, the anti-obesity and anti-inflammation effects of mulberry extract on Ad36 were evaluated in mice.

Quantification of ridging in ferritic stainless steel sheets by electron backscattered diffraction R-value maps.

In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sheet was discussed using this map.

Immunogenicity and safety of H1N1 influenza hemagglutinin protein expressed in a baculovirus system.

Although most influenza vaccines are produced in eggs, new types of vaccines must be developed. In this study, the immunogenicity and safety of a baculovirus-expressed hemagglutinin (HA) of H1N1 influenza virus (Korea/01/2009; designated "HA-Bac-K") was compared with those of a commercially available baculovirus-expressed HA (designated "HA-Bac-C") and an Escherichia coli-expressed HA (designated "HA-E. Coli-K").
