Abstract
BACKGROUND Asthma is the most common chronic disease in children. Underlying immunologic mechanisms-in particular of different phenotypes-are still just partly understood. The objective of the study was the identification of distinct cellular pathways in allergic asthmatics (AA) and nonallergic asthmatics (NA) vs healthy controls (HC). METHODS Peripheral blood mononuclear cells (PBMCs) of steroid-naïve children (n(AA/NA/HC) = 35/13/34)) from the CLARA study (n = 275) were stimulated (anti-CD3/CD28, LpA) or kept unstimulated. Gene expression was investigated by transcriptomics and quantitative RT-PCR. Differentially regulated pathways between phenotypes were assessed after adjustment for sex and age (KEGG pathways). Networks based on correlations of gene expression were built using force-directed graph drawing. RESULTS Allergic asthmatics vs NA and asthmatics overall vs HC showed significantly different expression of Ca2+ and innate immunity-associated pathways. PCR analysis confirmed significantly increased Ca2+ -associated gene regulation (ORMDL3 and ATP2A3) in asthmatics vs HC, most prominent in AA. Innate immunity receptors (LY75, TLR7), relevant for virus infection, were also upregulated in AA and NA compared to HC. AA and NA could be differentiated by increased ATP2A3 and FPR2 in AA, decreased CLEC4E in AA, and increased IFIH1 expression in NA following anti-CD3/28 stimulation vs unstimulated (fold change). CONCLUSIONS Ca2+ regulation and innate immunity response pattern to viruses were activated in PBMCs of asthmatics. Asthma phenotypes were differentially characterized by distinct regulation of ATP2A3 and expression of innate immune receptors (FPR2, CLEC4E, IFIH1). These genes may present promising targets for future in-depth investigation with the long-term goal of more phenotype-specific therapeutic interventions in asthmatics.

Abstract
BACKGROUND Allergic and non-allergic childhood asthma has been characterized by distinct immune mechanisms. While interferon regulating factor 1 (IRF-1) polymorphisms (SNPs) influence atopy risk, the effect of SNPs on asthma phenotype-specific immune mechanisms is unclear. We assessed whether IRF-1 SNPs modify distinct immune-regulatory pathways in allergic and non-allergic childhood asthma (AA/NA). METHODS In the CLARA study, asthma was characterized by doctor's diagnosis and AA vs NA by positive or negative specific IgE. Children were genotyped for four tagging SNPs within IRF-1 (n = 172). mRNA expression was measured with qRT-PCR. Gene expression was analyzed depending on genetic variants within IRF-1 and phenotype including haplotype estimation and an allelic risk score. RESULTS Carrying the risk alleles of IRF-1 in rs10035166, rs2706384, or rs2070721 was associated with increased risk for AA. Carrying the non-risk allele in rs17622656 was associated with lower risk for AA but not NA. In AA carrying the risk alleles, an increased pro-inflammatory expression of ICAM3, IRF-8, XBP-1, IFN-γ, RGS13, RORC, and TSC2 was observed. NOD2 expression was decreased in AA with risk alleles in rs2706384 and rs10035166 and with risk haplotype. Further, AA with risk haplotype showed increased IL-13 secretion. NA with risk allele in rs2070721 compared to non-risk allele in rs17622656 showed significantly upregulated calcium, innate, mTOR, neutrophil, and inflammatory-associated genes. CONCLUSION IRF-1 polymorphisms influence the risk for childhood allergic asthma being associated with increased pro-inflammatory gene regulation. Thus, it is critical to implement IRF-1 genetics in immune assessment for childhood asthma phenotypes.

Abstract
More than 50% of the world's population feeds on rice. Soils used for rice production are mostly managed under submerged conditions (paddy soils). This management, which favors carbon sequestration, potentially decouples surface from subsurface carbon cycling. The objective of this study was to elucidate the long-term rates of carbon accrual in surface and subsurface soil horizons relative to those of soils under nonpaddy management. We assessed changes in total soil organic as well as of inorganic carbon stocks along a 2000-year chronosequence of soils under paddy and adjacent nonpaddy management in the Yangtze delta, China. The initial organic carbon accumulation phase lasts much longer and is more intensive than previously assumed, e.g., by the Intergovernmental Panel on Climate Change (IPCC). Paddy topsoils accumulated 170-178 kg organic carbon ha(-1) a(-1) in the first 300 years; subsoils lost 29-84 kg organic carbon ha(-1) a(-1) during this period of time. Subsoil carbon losses were largest during the first 50 years after land embankment and again large beyond 700 years of cultivation, due to inorganic carbonate weathering and the lack of organic carbon replenishment. Carbon losses in subsoils may therefore offset soil carbon gains or losses in the surface soils. We strongly recommend including subsoils into global carbon accounting schemes, particularly for paddy fields.

Abstract
BACKGROUND Preoperative stress influences perioperative complications. Their severity is influenced by advanced information and previous experience. This study evaluates the emotional effects of these factors. METHODS In a prospective observational study we documented existing anaesthesiological pre-information and previous experience of 461 patients (255 w/206 m) individually. In addition, we recorded the affective emotional condition of each patient before and after the premedication visit via a visual analogue scale (VAS) and a test of current stress (KAB). RESULTS 248 patients had previous anaesthesiological pre-information. Of those 61 were of a negative nature. These patients showed a significantly higher level of stress and anxiety compared to those with positive information. 41 of 388 patients reported bad experiences with increased anxiety and stress. The premedication visits caused a significant attenuation of the overall stress level in patients with negative experience/information. CONCLUSION During the individual premedication visit, patients should be asked directly about negative pre-information and perioperative experience. Thus the conversation can be customised to the individual stress factors and show empathy as well. Independent of any medical intervention, this approach can be an effective contribution to stress reduction.
