Although atopic dermatitis (AD) is known to be a representative skin disorder, it also affects the systemic immune response. In a recent study, myoblasts were shown to be involved in the immune regulation, but the roles of muscle cells in AD are poorly understood. We aimed to identify the relationship between mitochondria and atopy by genome-wide analysis of skeletal muscles in mice. We induced AD-like symptoms using house dust mite (HDM) extract in NC/Nga mice. The transcriptional profiles of the untreated group and HDM-induced AD-like group were analyzed and compared using microarray, differentially expressed gene and functional pathway analyses, and protein interaction network construction. Our microarray analysis demonstrated that immune response-, calcium handling-, and mitochondrial metabolism-related genes were differentially expressed. In the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology pathway analyses, immune response pathways involved in cytokine interaction, nuclear factor-kappa B, and T-cell receptor signaling, calcium handling pathways, and mitochondria metabolism pathways involved in the citrate cycle were significantly upregulated. In protein interaction network analysis, chemokine family-, muscle contraction process-, and immune response-related genes were identified as hub genes with many interactions. In addition, mitochondrial pathways involved in calcium signaling, cardiac muscle contraction, tricarboxylic acid cycle, oxidation-reduction process, and calcium-mediated signaling were significantly stimulated in KEGG and Gene Ontology analyses. Our results provide a comprehensive understanding of the genome-wide transcriptional changes of HDM-induced AD-like symptoms and the indicated genes that could be used as AD clinical biomarkers.

Calcium Intake is Negatively Associated with Bone Loss During Lactation: A Pilot Study

Calcium (Ca) requirements during lactation are unknown. We investigated the association between Ca intake and bone mineral density (BMD) during lactation. Twenty-one pregnant women with singletons (non-breastfeeding [NBF] n=7; breastfeeding [BF] n=14) were enrolled before delivery. Ca intake during the 3rd trimester and 6 months postpartum was assessed by food frequency questionnaire and interview. Maternal BMD was measured by dual energy X-ray absorptiometry at the lumbar spine, femoral neck, trochanter, intertrochanter (IT), and total hip at delivery and weaning (or 6 months postpartum). The association of Ca intake with % change of BMD (%ㅿBMD) and change of Z-score (ㅿZ) were assessed by linear regression and Spearman’s rank correlation coefficient. No association was observed in NBF women. Similarly, %ㅿBMD and 3rd trimester Ca intake were not associated in BF women. However, Ca intake during lactation was positively associated with IT ㅿZ (β: 0.613, p=0.02). Ca:P ratio during lactation was also positively correlated with IT ㅿ%BMD (β: 0.587, p=0.03). Higher intake of Ca during lactation may prevent lactation-related bone loss at the IT.
Electrical characteristics of heterogeneous polymer layers in PEDOT:PSS films

<P>(3,4-Ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a representative conducting polymer, is environment-friendly and offers easy processing and flexibility owing to its hydro-dispersive properties. In this study, we investigated the electrical properties of PEDOT:PSS films with H2SO4/DMSO post-treatment. PEDOT:PSS is an electrolyte complex that has been attracting attention as a next-generation transparent electrode. The PEDOT:PSS films are composed of two heterogeneous phases: a PSS-rich layer and a PEDOT-rich layer. The PSS-rich layer is observed to be a homogeneous phase that does not influence the electrical properties. Thus, the PSS-rich layer, which occupies a large area of the PEDOT:PSS films, was removed to obtain films having high electrical properties. Both the layers exhibit a homogeneous phase regardless of their electrical properties. In particular, the PSS-rich layer without the PEDOT chains does not affect the electrical properties, since it does not contribute to hole transport. The heterogeneity of the PEDOT:PSS films with good electrical properties has been revealed by eliminating the unnecessary PSS-rich layers. The highest electrical conductivity obtained was 2239 S cm<SUP>−1</SUP>, which is about 4.1 times higher than that of the pristine PEDOT:PSS films, for the films involving 15 M H2SO4/DMSO post-treatment.</P>

The occurrence of osteoporosis gradually increases within the aging population. As the side effects of therapeutic agents currently used for osteoporosis are increasing, the development of preventive and therapeutic agents derived from natural products without any long-term side effects is important. Here, we investigated the effect of wheat seedling extract (WSE) on the RANKL-mediated differentiation, fusion, and function of osteoclasts. WSE inhibited the differentiation of RANKL-induced bone marrow macrophages and phosphorylation of AKT and ERK. Moreover, the protein and mRNA expression levels of c-Fos and NFATc1 as well as RANKL-induced transcription of TRAP and OSCAR were suppressed by WSE treatment. DC-STAMP and cathepsin K, which are essential for cell fusion and bone degradation, were also inhibited by WSE. Furthermore, eight components constituting WSE were confirmed to decrease the osteoclast TRAP activity. Taken together, WSE may have potential implications as a useful therapeutic or preventive agent for inhibition of bone loss.
