The synergistic effect of ZnO and GO nanostructures on the surface modification of mild steel before theacrylic resin coating was studied. Firstly, the steel surface was pretreated in the presence of ultrasonicirradiation, and then ZnO nanostructures were synthesized by the cyclic voltammetry technique. GOnanosheets prepared by the modified hummer’s method were deposited on ZnO-containing surfaces usingtheelectrophoreticdeposition(EPD)technique.GOcoatingswiththicknessesof2.84,4.47and9.42mmwereobtained by varying the EPD time, and the 4.47 mm was found as the optimum value for the fabrication ofhybrid ZnO/GO structures. All samples were then covered with a thin layer of acrylic resin (10 mm) by thespin coating technique. The results indicated that the sample with underneath of hybrid ZnO/GOnanostructures shows significant improvement in anti-corrosion performance. In other words, Rp isincreased from 150,000 V cm2 (in the rein coated sample) to 380,000 V cm2 (in the sample with hybridnanostructures). The resulting surface has the potential to use as protective and glossy black coatings. Theroleof underneathnature,surface roughness, and molecular interactionsbetweenoxygenfunctionalgroupsof ZnO, GO, resin, and the metal in the enhanced corrosion protection was illustrated.

Recent studies suggest that inclusion of soy product in the diet may have favorable effects on relief of cardiovascular diseases (CVDs) and risk factors. These effects might be associated with the presence of specific polymorphism in gene. The aim of this study was to examine the effects of consumption of soy flour fortified bread on cardiovascular risk factors in overweight and obese women according to APOE genotype. In a randomized cross-over clinical trial 30 overweight and obese women received a mild weight loss diet and assigned to a regular diet and a soy bread diet, each for 6 weeks and a washout period for 20 days. Subjects in the soy bread diet were asked to replace 120 grams of their daily usual bread intake with equal amount of soy bread. No significant effects of soy bread on serum lipid, systolic blood pressure and anthropometric indices were observed compared to the regular diet (p > 0.05). For diastolic blood pressure (DBP), comparison of mean differences between two groups showed a marginally significant effect of soy bread (p = 0.06). Compared to regular diet, soy bread had a significant ef-fect on DBP in E2 genotype group (ε2/ε2) (p = 0.03). Having ε2 allele may influences responses of CVD risk factor to soy bread consumption. However more nutrigenetic studies are required.

Purpose: To evaluate visual and anatomical results and identify factors that influence vitrectomy and silicone oil(SO) injection outcomes in proliferative diabetic retinopathy (PDR). Methods: This retrospective study included 236 eyes with PDR that were undergoing vitrectomy and SO injectionwith >3-month follow-up. The primary outcomes were final best-corrected visual acuity (BCVA) and retinalattachment rate. Results: At the final visit (mean, 88 ± 58 weeks), complete, partial, and no retinal attachment were observed in86.9%, 10.6%, and 2.5% of patients, respectively. A total of 155 eyes had experienced SO removal, while 81had SO in place. The mean initial BCVA was 1.9 ± 0.7 logarithm of the minimum angle of resolution (logMAR)and significantly improved to 1.7 ± 0.8 logMAR (p = 0.001). Initial macular detachment (adjusted odds ratio[AOR], 0.25), development of iatrogenic break (AOR, 0.25), and use of heavy SO (AOR, 0.13) were independentlyassociated with a lower risk of final retinal attachment, and SO removal was associated with a higherincidence (AOR, 7.55). Better baseline BCVA was associated with a higher risk of final BCVA ≥20 / 200. Conclusions: Despite an encouraging outcome based on anatomical data in advanced PDR treated with vitrectomyand SO, the functional prognosis was not satisfying for patients. Eyes with better vision at baseline hada more favorable prognosis, whereas eyes with initial macular detachment, intraoperative iatrogenic break, orheavy SO showed more unfavorable outcomes. In selected cases, extending the time of SO use did not worsenthe prognosis.
