A state estimation problem is studied for a class of coupled outputs discrete-time networks with stochastic measurements, i.e., the measurements are missing and disturbed with stochastic noise. The considered networks are coupled with outputs rather than states, are coupled with different inner coupling matrices rather than identical inner ones. By using Lyapunov stability theory combined with stochastic analysis, a novel state estimation scheme is proposed to estimate the states of discrete-time complex networks through the available output measurements, where the measurements are stochastic missing and are disturbed with Brownian motions which are caused by data transmission among nodes due to communication unreliability. State estimation conditions are derived in terms of linear matrix inequalities (LMIs). A numerical example is provided to demonstrate the validity of the proposed scheme.

The Association of GSDMB and ORMDL3 Gene Polymorphisms With Asthma: A Meta-Analysis
Chun-Ni Zhao,Ye Fan,Jian-Jun Huang,Hai-Xia Zhang,Tao Gao,Cong Wang,Tong Wang,Li-Fang Hou 대한천식알레르기학회 2015 Allergy, Asthma & Immunology Research Vol.7 No.2
Purpose: ORM1-like 3 (ORMDL3) belongs to a highly conserved protein family which is anchored as transmembrane protein in the endoplasmic reticulum. Gasdermin B (GSDMB) is adjacent to ORMDL3 on chromosome 17q21.2 and belongs to the gasdermin-domain containing the protein family(GSDM family). Recent reports suggest that GSDMB and ORMDL3 are associated with asthma in several populations. However, genetic associationstudies that examined the association of GSDMB and ORMDL3 gene variants with asthma showed conflicting results. To assess whether combinedevidence shows the association between GSDMB/ORMDL3 polymorphism and asthma. Methods: A bibliographic search from MEDLINE identified13 original articles using the search keywords ‘GSDMB’, ‘ORMDL3’, and ‘asthma’. An updated literature-based meta-analysis involving 6,691 subjectswith asthma, 9,281 control individuals, and 1,360 families were conducted. Meta-odds ratios (ORs) and 95% confidence intervals (CIs) basedon the fixed effects model or the random effects model depended on Cochran’s Q-statistic and I2 values. Data from case-control and TDT studieswere analyzed in an allelic model using the Catmap software. Results: We selected and identified 3 SNPs of ORMDL3 associated with asthma(rs8076131: OR=1.10; 95% CI, 1.02-1.20; P=0.012. rs12603332: OR=1.15; 95% CI, 1.05-1.25; P=0.002. rs3744246: OR=1.10; 95% CI, 1.02-1.17;P=0.008) and 1 SNP of GSDMB associated with asthma (rs7216389: OR=1.37; 95% CI, 1.27-1.47; P<0.01). Publication bias was estimated usingmodified Egger’s linear regression test proposed by Harbordetal and revealed no evidence of biases. Furthermore, cumulative meta-analysis in chronologicalorder showed the inclination toward significant association for rs7216389 and rs12603332 with continually adding studies, and the inclinationtoward null-significant association for rs3744246 and rs8076131. Conclusions: Moderate evidence exists for associations of the ORMDL3rs8076131, rs12603332, and rs3744246 and GSDMB rs7216389 variants with asthma. Large sample size and representative population-based studiesand TDT studies with homogeneous asthmatic patients and well-matched controls are warranted to confirm this finding.

Flavonoid glycosides are metabolized byintestinal bacteria, giving rise to a wide range of phenolicacids that may exert systemic effects in the body. Themicrobial metabolism of flavonoids extracted from theleaves of Diospyros kaki (FLDK) by intestinal bacteria wasinvestigated in vitro. High-performance liquid chromatography/linear trap quadrupole orbitrap mass spectrometrywas performed to analyze the metabolites of flavonoidsin vivo using Xcalibur2.1 software. The results showed thatthe levels of flavonoid glycosides and flavonoid aglyconesdecreased rapidly in the process of microbial metabolismby intestinal bacteria in vitro, and the metabolic rate maybe related to the concentration of intestinal bacteria in theculture solution. In vivo metabolites of FLDK weredetected in rat plasma and urine after oral administration ofFLDK. Eight flavonoids were identified in the urine, andthree were identified in the plasma; however, flavonoidaglycones were not found in the plasma.
