BACKGROUND Several studies have reported that the walking trail making test(WTMT)completion time is significantly higher in patients with developmental coordination disorders and mild cognitive *** hypothesized that WTMT performance would be altered in older adults with white matter hyperintensities(WMH).AIM To explore the performance in the WTMT in older people with *** In this single-center,observational study,25 elderly WMH patients admitted to our hospital from June 2019 to June 2020 served as the WMH group and 20 participants matched for age,gender,and educational level who were undergoing physical examination in our hospital during the same period served as the control *** participants completed the WTMT-A and WTMT-B to obtain their gait parameters,including WTMT-A completion time,WTMT-B completion time,speed,step length,cadence,and stance phase *** matter lesions were scored according to the Fazekas *** neuropsychological assessments were carried out to assess cognitive *** relationships between WTMT performance and cognition and motion in elderly patients with WMH were analyzed by partial Pearson correlation *** Patients with WMH performed significantly worse on the choice reaction test(CRT)(0.51±0.09 s vs 0.44±0.06 s,P=0.007),verbal fluency test(VFT,14.2±2.75 vs 16.65±3.54,P=0.012),and digit symbol substitution test(16.00±2.75 vs 18.40±3.27,P=0.010)than participants in the control *** WMH group also required significantly more time to complete the WTMT-A(93.00±10.76 s vs 70.55±11.28 s,P<0.001)and WTMT-B(109.72±12.26 s vs 82.85±7.90 s,P<0.001).WTMT-A completion time was positively correlated with CRT time(r=0.460,P=0.001),while WTMT-B completion time was negatively correlated with VFT(r=-0.391,P=0.008).On the WTMT-A,only speed was found to statistically differ between the WMH and control groups(0.803±0.096 vs 0.975±0.050 m/s,P<0.001),whereas on the WTMT-B,the WMH group exhibited a sign

Modification of food protein fibrils: During and after fibrillization

引用

Food Science and Human Wellness 2024年

作者： Kefan Ouyang Hexiang Xie hua Xiong qiang Zhao Wenjun Wang State Key Laboratory of Food Science and Resources， Nanchang University Jiangxi Key Laboratory of Natural Products and Functional Food， College of Food Science and Engineering， Jiangxi Agricultural University

Fibrillization endows food proteins with anisotropic nanostructures， significantly enhancing their functional properties. The resultant food protein fibrils (FPFs) have garnered attention for their diverse applications across the food industry. However， the full potential of FPFs is hindered by inherent challenges， particularly their limited stability. This review critically examines the formation of FPFs in food processing， the new protein sources， and on the modification strategies of FPFs， thereby unlocking new avenues for FPF utilization in food processing. In particular， the strategies during and after fibrillization are highlighted. The first strategy is to modify the structure and function of protein fibrils by influencing fibrillization， such as through pretreatment， incubation conditions， nuclei induction， and ingredient interactions. The second strategy is to modify the mature FPFs by regulating their properties and interactions with other components. The review also discusses the potential applications and challenges of FPFs in food systems， such as food preservation， functional food design， and novel delivery carriers.
