Background: Apolipoprotein A2 (APO A2) is the second most abundant structural apolipoprotein in high density lipoprotein. Several studies have examined the possible effect of APO A2 on atherosclerosis incidence. Due to the role of inflammation in atherosclerosis, we aimed to determine the relationship between APO A2 −265T/C polymorphism and inflammation as a risk factor in type 2 diabetes mellitus (T2DM) patients. Methods: In total, 180 T2DM patients, with known APO A2 −265T/C polymorphism, were recruited for this comparative study and were grouped equally based on their genotypes. Dietary intakes, anthropometric parameters, lipid profile, and inflammatory markers (i.e., pentraxin 3 [PTX3], high-sensitivity C-reactive protein [hs-CRP], and interleukin 18) were measured. The data were analyzed using an independent t-test, a chi-square test, and the analysis of covariance. Results: After adjusting for confounding factors, in the entire study population and in the patients with or without obesity, the patients with the CC genotype showed higher hs-CRP (P=0.001, P=0.008, and P=0.01, respectively) and lower PTX3 (P=0.01, P=0.03, and P=0.04, respectively) in comparison with the T allele carriers. In the patients with the CC genotype, no significant differences were observed in the inflammatory markers between the obese or non-obese patients. However, regarding the T allele carriers, the plasma hs-CRP level was significantly higher in the obese patients compared to the non-obese patients (P=0.01). Conclusion: In the T2DM patients, the CC genotype could be considered as a risk factor and the T allele as a protective agent against inflammation, which the latter effect might be impaired by obesity. Our results confirmed the anti-atherogenic effect of APO A2, though more studies are required to establish this effect.

Silica aerogel surface modifications with chelating agents for adsorption/removal of metal ions have been reported in recent years. This investigation reported the preparation of silica aerogel (SA) adsorbent coupled with metal chelating ligands of 4-amino-5-methyl-1,2,4-triazole-3(4H)-thion (AMTT) and its application for selective adsorption of Hg(II) ion. The adsorbent was characterized by Fourier transform infrared spectra (FTIR) and thermo gravimetric analysis (TGA) measurements, nitrogen physisorption and scanning electron microscope (SEM). Optimal experimental conditions including pH, temperature, adsorbent dosage and contact time have been established. Langmuir and Freundlich isotherm models were applied to analyze the experimental data. The best interpretation for the experimental data given by the Langmuir isotherm equation and the maximum adsorption capacity of the modified silica gel and silica aerogel was 142.85 and 17.24mgg−1, respectively. Thermodynamic parameters such as Gibbs free energy (ΔGo), standard enthalpy (ΔHo) and entropy change (ΔSo) were investigated. The adsorbed Hg(II) on the SA-AMTT adsorbents could be completely eluted by 1.0M KBr solution and recycled at least four times without the loss of adsorption capacity. The results of the present investigation illustrate that modified silica aerogel with AMTT could be used as an adsorbent for the effective removal of Hg(II) ions from aqueous solution.

In the present study, preparation of acrylonitrile-butadiene-styrene (ABS) membrane was investigated viaphase inversion method. ABS membrane is sensitive to preparation conditions. Therefore, the effect of solvent/nonsolventtype and concentration of additive and ABS was evaluated on the morphology, tensile strength and car washwastewater treatment. Polyethylene glycol was used as an additive. The results show that nonsolvent type significantlyaffects the morphology and consequently the flux and rejections of the pollution indices. Increasing concentration ofadditive and ABS in the casting solution leads to formation of denser and thinner membranes that have lower flux andhigher rejections of the pollution indices.

Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates including 67 isolates obtained from symptomatic leaves and ears of wheat, barley, and wild grasses from two wheatgrowing region in Iran as well as 206 isolates from our collection from other regions in Iran which were isolated in our previous studies. Mating type genes phylogeny was successfully used to determine the species identity and relationships among isolates within the Phaeosphaeria spp. complex. In this study, we reported seven new host records for Phaeosphaeria species and the Phaeosphaeria avenaria f. sp. tritici 3 group was first reported from Iran in this study. Mating type distribution among Phaeosphaeria species was determined. Both mating types were present in all sampling regions from Iran. We observed skewed distribution of mating types in one region (Kohgiluyeh va Boyer-Ahmad) and equal distribution in the other region (Bushehr). However, when considering our entire dataset of 273 Iranian Phaeosphaeria isolates, the ratio of mating types was not deviated significantly from 1:1 suggesting possibilities for isolates of opposite mating type to interact and reproduce sexually, although the sexual cycle may infrequently occur in some regions especially when the climatic conditions are unfavorable for teleomorph development.

Let H(D) be the space of all holomorphic functions on the open unit disc D in the complex plane C. In this paper, we investigate the boundedness and compactness of the generalized integration operatorI(n)g,ϕ(f)(z) = Z0f(n)(ϕ(ξ))g(ξ) dξ, z ∈ D, between Bloch-type and weighted Dirichlet-type spaces, where ϕ is a holomorphic self-map of D, n ∈ N and g ∈ H(D).

In this study, α,ω-diamino polyoxytetramethylene (APOTM) was used as a new polyoxyalkylene hardener of diglycidyl ether of bisphenol A (DGEBA) epoxy resin. To reinforce the thermo-mechanical behavior of the corresponding epoxy networks, the curing processes were performed in the presence of amine-functionalized silica nanoparticles (AFSNP"s). Three different contents of AFSNP"s, i.e. 5.0, 7.5 and 10.0 wt%, were employed for covalent embedding into the resultant DGEBA/APOTM epoxy networks. Therefore, three epoxy-silica films labeled by EN/AFSNP′s-5, EN/AFSNP′s-7.5 and EN/AFSNP′s-10 were fabricated. The AFSNP′s-loaded DGEBA/APOTM epoxies showed superior thermo-stability in comparison with the neat epoxy counterpart. According to the results obtained from DMTA measurements, the storage moduli (E" values) of the epoxies were significantly improved by adding the organically modified silica nanofiller.

Objectives: Brucellosis is a systemic disease with a wide spectrum of clinical manifestations. This study aimed to determine the seroprevalence of brucellosis in human immunodeficiency virus (HIV) infected patients in Hamadan Province in the west of Iran. Methods: A total of 157 HIV-infected patients were screened through standard serological tests, including Wright’s test, Coombs’ Wright test, and 2-mercaptoethanol Brucella agglutination test (2ME test), blood cultures in Castaneda media, and CD4 counting. Data were analyzed using Stata version 11. Results: Wright and Coombs’ Wright tests were carried out, and only 5 (3.2%) patients had positive serological results. However, all patients had negative 2ME results, and blood cultures were negative for Brucella spp. Moreover, patients with positive serology and a mean CD4 count of 355.8 ± 203.11 cells/mL had no clinical manifestations of brucellosis, and, and the other patients had a mean CD4 count of 335.55 ± 261.71 cells/mL. Conclusion: Results of this study showed that HIV infection is not a predisposing factor of acquiring brucellosis.

This paper deals with the instability and resonant phenomena in distribution systems with multiple grid-connected inverters with an LCL output filter. The penetration of roof-top and other types of small photovoltaic (PV) grid-connected systems is rapidly increasing in distribution grids due to the attractive incentives set forth by different governments. When the number of such grid-connected inverters increases, their interaction with the distribution grid may cause undesirable effects such as instability and resonance. In this paper, a grid system with several grid-connected inverters is studied. Since proportional-resonant (PR) controllers are becoming more popular, it is assumed that most inverters use this type of controller. An LCL filter is also considered at the inverters output to make the case as realistic as possible. A complete modeling of this system is presented. Consequently, it is shown that such a system is prone to instability due to the interactions of the inverter controllers. A modification of PR controllers is presented where the output capacitor is virtually decreased. As a result, the instability is avoided. Simulation results are presented and show a good agreement with the theoretical studies. Experimental results obtained on a laboratory setup show the validity of the analysis.
