Honglei Zhu,Duo Li 국제구조공학회 2023 Structural Engineering and Mechanics, An Int'l Jou Vol.85 No.4

Edible coatings are one of the most innovative methods to preserve the quality and increase the shelf life of fresh fruits and vegetables. A successful edible coating should have a barrier against gases, especially oxygen and water vapor, and have good surface characteristics. Today, chitosan coating is widely used due to its properties, such as non-toxic, biodegradable, and biocompatibility. Is. Coating the surface of fruits and vegetables with chitosan increases shelf life due to reducing weight loss and reducing respiration rate and also reduces decay due to its antimicrobial and anti-fungal effect. This work discusses the effect of using chitosan coating containing chamomile extract to increase fresh vegetables’ shelf life. In addition to increasing the shelf life of vegetables, this method can be used as a solution for the economic management of human resources. The results of this method confirm the successful synthesis of these nanoparticles, and the results of applying this food coating on vegetables have been successful. They have increased the shelf life of vegetables such as basil and spinach.

This work provides a facile anodic electrodeposition method for synthesizing carbon coated α-Fe2O3 photoanode followedby annealing treatment with argon atmosphere. Compared with bare hematite photoanode, the carbon coated α-Fe2O3 photoanodesannealed at lower temperature (Fe2O3/C-L) and higher temperature (Fe2O3/C-H) have higher photocurrent densityas 0.3 and 0.5 mA cm−2 (at 1.23 V vs. RHE), respectively. The excellent PEC performance is attributed to the synergisticreaction of carbon and vacancy oxygen. The morphology and properties of the sample were characterized with scanningelectron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, UV–Vis spectra, X-raydiffractometry, X-ray photoelectron spectra, and photoelectrical measurements.

Background Salt stress is a devastating environmental stress that causes plant growth inhibition and yield reduction. Objective The identification of salt-tolerant genes brings hope for the generation of salinity-tolerant crop plants through molecular breeding. Methods In this study, one salt-sensitive and one salt-tolerant maize inbred line were screened from 242 maize inbred lines. Reactive oxygen species (ROS)-related enzyme activities were detected and salt-responsive comparative transcriptome analysis was performed for control and 220 mM NaCl treated maize leaves. Results Salt-tolerant maize inbred line (L87) showed higher ROS-related enzyme (SOD, POD, APX and CAT) activities and accumulated relatively lower levels of ROS under salt stress. Of the total DEGs, 1856 upregulated DEGs were specific to L87, including stress tolerance-related members of the 70kDa family of heat shock proteins (Hsp70s) and aquaporins. The DEGs involved in the abscisic acid (ABA), ethylene, jasmonic acid (JA) and salicylic acid (SA) signal transduction pathways may determine the difference in salt tolerance between the two varieties, especially one central component SnRK2, that positively regulates ABA signaling and was only upregulated in L87. Analysis of DEGs related to ROS scavenging showed that some peroxidase (POD), glutathione S-transferase (GST), catalase (CAT) and superoxide dismutase (SOD) genes specific to L87 probably enhanced its salt tolerance. The analysis of differentially expressed transcription factors (TFs) suggested that WRKY TFs could contribute to the difference in salt tolerance between the two maize lines. Conclusion Compared with Salt-sensitive maize inbred line (L29), L87 exhibits specific regulatory mechanisms related to salt tolerance, including plant hormone interactions, ROS scavenging and the regulation of TFs. Our study identifies new candidate genes that may regulate maize tolerance to salt stress and provides useful information for breeding maize with high salt resistance.

Crystallization Toughening of Fe-Based Amorphous Alloys Under Strain–Heat Coupling Effect

Wei Zhao,Jiacheng Yu,Mindong Hu,Honglei Hu,Junting Luo,Gong Li 대한금속·재료학회 2023 METALS AND MATERIALS International Vol.29 No.1

The crystallization toughening of Fe-based amorphous alloys under strain–heat coupling effect was studied. This effectinvolved annealing crystallization along with uniform plastic deformation under three-direction compressive stress. Resultsshowed that the Fe-based amorphous alloys subjected to strain–heat coupling action had greater toughening effect than thosesubjected to single low-temperature annealing. The difference was due to the change in morphology of the precipitated crystalphase and the substantial amount of free volume introduced into an amorphous matrix through uniform plastic deformation,which was conducive to the proliferation of shear bands. However, excessive plastic deformation led to direct fracture ofmaterials after elastic deformation.

Background: Hyperuricemia has been commonly found in patients with nonalcoholic fatty liver disease (NAFLD). This study aimed to clarify the causal relationship between NAFLD and hyperuricemia and to explore their underlying mechanisms. Methods: First, we evaluated the impact of NAFLD on development of hyperuricemia in a cohort of 5541 hyperuricemia-free individuals. Second, we analyzed the involvement of xanthine oxidase (XO), a rate-limiting enzyme catalyzes uric acid production, in the relationship between NAFLD and hyperuricemia in cultured HepG2 cells and a murine model of NAFLD. Results: In the first study, 7-year prospective analysis found that NAFLD was strongly associated with subsequent development of hyperuricemia. Cox proportional hazards regression analyses showed that the age, gender, and body mass index adjusted hazard ratio (95% CI) for incident hyperuricemia was 1.609 (1.129 - 2.294) in individuals with NAFLD compared with those without NAFLD. In the second study, we observed that the expression and activity of XO were significantly increased in cellular and mouse models of NAFLD. Knocking down XO expression or inhibiting XO activity significantly inhibited uric acid production and attenuated free fatty acids (FFA)-induced fat accumulation in HepG2 cells. Inhibition of XO activity also significantly decreased serum uric acid levels and ameliorated high fat diet-induced hepatic steatosis in mice. Further experiments indicated that XO regulates the activation of NLRP3 inflammasome, which may be essential for the regulatory effect of XO on NAFLD. Conclusions: XO promotes hyperuricemia and the development of NAFLD, which may serve as a novel therapeutic target for NAFLD.

Tuo Xin,Guiju Liu,Wenshuang Liang,Rongsheng Cai,Honglei Feng,Chen Li,Jian Li,Yiqian Wang 대한금속·재료학회 2018 METALS AND MATERIALS International Vol.24 No.4

High-resolution transmission electron microscopy is used to investigate the deformation behaviors of cementite lamellaein the heavily cold-drawn piano wires. Three distinct morphologies of cementite are observed, namely, complete lamella,partly-broken lamella and nearly-disappeared lamella. For the complete cementite lamella, it remains a single-crystallinestructure. For the partly-broken cementite lamella, polycrystalline structure and neck-down region appear to release theresidual strain. The lattice expansion of ferrite takes place in two perpendicular directions indicating that the carbon atomsdissolve from cementite into ferrite lattices. An orientation relationship is found between ferrite and cementite phases in thecold-drawn pearlitic wire.

Background: Accurate serum total thyroxine (TT4) measurement is important for thyroid disorder diagnosis and management. We compared the performance of six automated immunoassays with that of isotope-diluted liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) as the reference method. We also evaluated the correlation of thyroid stimulating hormone (TSH) with TT4 measured by ID-LC-MS/MS and immunoassays. Methods: Serum was collected from 156 patients between October 2015 and January 2016. TT4 was measured by immunoassays from Abbott (Architect), Siemens (ADVIA Centaur XP), Roche (E601), Beckman-Coulter (Dxi800), Autobio (Autolumo A2000), and Mindray (CL-1000i), and by ID-LC-MS/MS. Results were analyzed using Passing–Bablok regression and Bland–Altman plots. Minimum requirements based on biological variation were as follows: a mean bias of ≤4.5% and total imprecision (CV) of ≤3.7%. Results: All immunoassays showed a correlation >0.945 with ID-LC-MS/MS; however, the slope of the Passing–Bablok regression line varied from 0.886 (Mindray) to 1.23 (Siemens) and the intercept from -12.8 (Siemens) to 4.61 (Mindray). Only Autobio, Beckman-Coulter, and Roche included the value of one in the 95% confidence interval for slope. The mean bias ranged from -10.8% (Abbott) to 9.0% (Siemens), with the lowest value noted for Roche (3.5%) and the highest for Abbott (-10.8%). Only Abbott and Roche showed within-run and total CV ≤3.7%. Conclusions: Though all immunoassays correlated strongly with ID-LC-MS/MS, most did not meet the minimum clinical requirement. Laboratories and immunoassay manufacturers must be aware of these limitations.

Background: Thyroid diseases are highly prevalent worldwide, but their diagnosis remains a challenge. We established reference intervals (RIs) for thyroid-associated hormones and evaluated the prevalence of thyroid diseases in China. Methods: After excluding outliers based on the results of ultrasound screening, thyroid antibody tests, and the Tukey method, the medical records of 20,303 euthyroid adults, who visited the Department of Health Care at Peking Union Medical College Hospital from January 2014 to December 2018, were analyzed. Thyroid-associated hormones were measured by the Siemens Advia Centaur XP analyzer. The RIs for thyroid-associated hormones were calculated according to the CLSI C28-A3 guidelines, and were compared with the RIs provided by Siemens. The prevalence of thyroid diseases over the five years was evaluated and compared using the chi-square test. Results: The RIs for thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), total thyroxine (TT4), and total triiodothyronine (TT3) were 0.71–4.92 mIU/L, 12.2–20.1 pmol/L, 3.9–6.0 pmol/L, 65.6–135.1 nmol/L, and 1.2–2.2 nmol/L, respectively. The RIs of all hormones except TT4 differed significantly between males and females. The RIs of TSH increased with increasing age. The prevalence of overt hypothyroidism, overt hyperthyroidism, subclinical hypothyroidism, and subclinical hyperthyroidism was 0.5% and 0.8%, 0.2% and 0.6%, 3.8% and 6.1%, and 3.3% and 4.7% in males and females, respectively, which differed from those provided by Siemens. Conclusions: Sex-specific RIs were established for thyroid-associated hormones, and the prevalence of thyroid diseases was determined in the Chinese population.
