In situ Gelatinization of Starch using Hot Stage Microscopy
Canhui Cai,Jinwen Cai,Lingxiao Zhao,Cunxu Wei 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.1
Starch gelatinization is important in food processingand industrial use. Granule swelling and gelatinizationtemperature of 11 starches from different plants wereinvestigated in situ using hot stage microscopy duringheating. The amylose content, swelling power, pastingtemperature and thermal property of these starches werealso measured. The results showed that hot stage microscopywas suitable for measuring granule swelling and thegelatinization temperature of starch during heating. Thesectional area swelling percentage of starch granulesmeasured using hot stage microscopy was significantlypositively correlated with the swelling power. The gelatinizationtemperature measured using hot stage microscopy wassignificantly positively correlated with the pasting temperatureand with the thermal property for all 11 starches. For ricestarches with the same crystallinity and similar size, thegelatinization temperature was negatively correlated withthe amylose content and positively correlated with theswelling power and the sectional area swelling percentageat 95ºC.

Multi-scale Nano/Micro Fiber Scaffolds with Different Topological Morphologies
Jianyong Feng,Ruixiang Xu,Jiaming Zhao,Lingxiao Zhang 한국섬유공학회 2022 Fibers and polymers Vol.23 No.4
The multi-scale fiber and topological morphologies had been shown to influence cell mitogenesis and chemotaxis,direct cell differentiation, and induce constructive host tissue remodeling responses. To simulate multi-layer meshworkarchitecture of extracellular matrix and regulate cell behavior, we prepared different topological scaffolds, such as 3Dprinting fiber scaffolds, poly(lactic acid) (PLA) electrospun fiber scaffolds, 3D printing/knitted fabric composite scaffolds,and PLA electrospinning/knitted fabric composite scaffolds. The surface morphology, pore diameter, thickness, stress-straincurve, electrical current, and other properties were studied. The aim is to prepare multi-scale nano/micro fiber scaffolds withdifferent topological morphologies and properties that can provide structural and mechanical support for potential tissueengineering applications.

Health-promoting Lifestyle in Patients after Percutaneous Coronary Intervention
Ling Xiao,Pan Wang,Qin Fang,Qinghua Zhao 대한심장학회 2018 Korean Circulation Journal Vol.48 No.6
Background and Objectives The purpose of this study was to determine the status of health-promoting behaviors in patients after percutaneous coronary intervention (PCI) and explore what factors affect healthy lifestyle behaviors. Methods A total of 120 patients with coronary artery disease after PCI was included in this study. The Health Promoting Lifestyle Profile (HPLP) II was used to assess health-promoting lifestyle behavior. Data analysis was performed by t-test, analysis of variance, and multiple linear stepwise regression analyses. Results The average age of the participants was 60.10±9.84 (range, 37–81) years old. Among the participants, 86.7% were men and 13.3% were women. In all, 24.2% of the patients had an excellent level of health-promoting lifestyle and 74.2% had a moderate level of health-promoting lifestyle. The spiritual growth scores were the highest, while stress management and physical activity scores were the lowest. The level of health-promoting lifestyle was higher for people with higher income and a diagnosis of stable angina. Conclusions Healthcare providers should focus on promoting physical exercise and stress management for patients after PCI. It is also necessary to keep an eye out for patients with low income and severe illness to encourage a health-promoting lifestyle in these subsets of patients.
