AIM： To assess the correlation between the serum hep-cidin-25 level and left ventricular mass ***： This study was a cross-sectional study conducted between March 2009 and April 2010. Demo-graphic and biochemical data, including the serum hep-cidin-25 level, were collected for chronic kidney disease （CKD） patients. Two-dimensional echocardiography was performed to determine the left ventricle mass （LVM）, left ventricular mass index （LVMI）, interventricular septum thickness （IVSd）, left ventricle posterior wall thickness （LVPW）, right ventricular dimension （RVD）, left atrium （LA） and ejection fraction （EF）.RESULTS： A total of 146 patients with stage 1 to 5 CKD were enrolled. Serum hepcidin-25 levels were 16.51 ± 5.2, 17.59 ± 5.32, 17.38 ± 6.47, 19.98 ± 4.98 and 22.03 ± 4.8 ng/mL for stage 1 to 5 CKD patients, respectively. Hepcidin-25 level was independently pre-dicted by the serum ferritin level （β = 0.6, P = 0.002） and the estimated glomerular fltration rate （β = -0.48, P = 0.04）. There were negative correlations between the serum hepcidin level and the LVM and LVMI （ P = 0.04 and P = 0.005, respectively）. Systolic blood pressure （BP） was positively correlated with the LVMI （ P = 0.005）. In the multivariate analysis, a decreased serum hepci-din-25 level was independently associated with a higher LVMI （β = -0.28, 95%CI： -0.48 - -0.02, P = 0.006） after adjusting for body mass index, age and systolic ***： A lower serum hepcidin level is associ-ated with a higher LVMI in CKD patients. Low hepcidin levels may be independently correlated with unfavor-able cardiovascular outcomes in this population.

Physical property improvement of fluid shortening using peanut oil-based diacylglycerols and their applications in sponge cake

Grain & Oil Science and Technology 2024年第3期7卷 150-158页

作者： Yilin Du Shuo Zou Yee-ying lee Yong Wang Zhen Zhang JNU-UPM International Joint Laboratory on Plant Oil Processing and Safety Department of Food Science and EngineeringJinan UniversityGuangzhouGuangdong 510632China School of Science Monash University MalaysiaBandar Sunway 47500SelangorMalaysia

Fluid shortening is an important ingredient in the production of sponge cake. Peanut oil with 0, 43% and 85% of diacylglycerol content was used as the base oil. Different emulsifiers, such as glycerol monostearate, soy lecithin and sucrose ester, and their respective amounts, were investigated. It was found that the addition of emulsifiers had a positive effect on water-absorbing capacity, air-absorbing capacity and viscosity of the oils. Glycerol monostearate was the preferred emulsifier for fluid shortening with a recommended addition of 1.5%. The effects of different diacylglycerol content on fluid shortening and their impact on sponge cake production was also investigated. The onset oxidation temperature of the oil could be increased from 253.21 ℃ for PO-TAG-based fluid shortening to 263.70 ℃ for PO-DAG85-based fluid shortening. And the increase in diacylglycerol content leading to a lower specific gravity of the batter, which was 1.06 g/mL, 1.02 g/mL and 0.98 g/mL prepared by PO-DAG, PO-DAG43 and PO-DAG85 shortening, respectively. The results showed that diacylglycerols can be used as base oils in fluid shortening to improve the crystal network and stability of fluid shortenings, thereby reducing the specific gravity of the batter and improving the structural properties of the cake. This will extend the potential applications of diacylglycerols and increase the variety of base oils available for fluid shortening preparation.

Nano-Micro Letters 2024年第2期16卷 1-14页

作者： Yijian Gao ying Liu Xiliang Li Hui Wang Yuliang Yang Yu Luo yingpeng Wan Chun‑sing lee Shengliang Li Xiao‑Hong Zhang College of Pharmaceutical Sciences Soochow UniversitySuzhou 215123People’s Republic of China Institute of Functional Nano&Soft Materials(FUNSOM) Soochow UniversitySuzhou 215123People’s Republic of China Center of Super‑Diamond and Advanced Films(COSDAF)&Department of Chemistry City University of Hong Kong83 Tat Chee AvenueKowloonHong Kong SARPeople’s Republic of China

Massive efforts have been concentrated on the advance of eminent near-infrared(NIR) photothermal materials(PTMs) in the NIR-Ⅱ window(1000–1700 nm), especially organic PTMs because of their intrinsic biological safety compared with inorganic PTMs. However, so far, only a few NIR-Ⅱresponsive organic PTMs was explored, and their photothermal conversion efficiencies(PCEs) still remain relatively low. Herein, donor–acceptor conjugated diradical polymers with open-shell characteristics are explored for synergistically photothermal immunotherapy of metastatic tumors in the NIR-Ⅱ window. By employing side-chain regulation, the conjugated diradical polymer TTB-2 with obvious NIR-Ⅱ absorption was developed, and its nanoparticles realize a record-breaking PCE of 87.7% upon NIR-Ⅱ light illustration. In vitro and in vivo experiments demonstrate that TTB-2 nanoparticles show good tumor photoablation with navigation of photoacoustic imaging in the NIR-Ⅱ window, without any side-effect. Moreover, by combining with PD-1 antibody,the pulmonary metastasis of breast cancer is high-effectively prevented by the efficient photo-immunity effect. Thus, this study explores superior PTMs for cancer metastasis theranostics in the NIR-Ⅱ window, offering a new horizon in developing radical-characteristic NIR-Ⅱ photothermal materials.

A touch sensor is an essential component in meeting the growing demand for human-machine interfaces. These sensors have been developed in wearable, attachable, and even implantable forms to acquire a wide range of information from humans. To be applied to the human body, sensors are required to be biocompatible and not restrict the natural movement of the body. Ionic materials are a promising candidate for soft touch sensors due to their outstanding properties, which include high stretchability, transparency, ionic conductivity, and biocompatibility. Here, this review discusses the unique features of soft ionic touch point sensors, focusing on the ionic material and its key role in the sensor. The touch sensing mechanisms include piezocapacitive, piezoresistive, surface capacitive, piezoelectric, and triboelectric and triboresistive sensing. This review analyzes the implementation hurdles and future research directions of the soft ionic touch sensors for their transformative potential. This paper introduces the increasing importance of touch sensors in human-machine interfaces and the role of soft ionic materials in enhancing the functionality of touch sensors. It provides detailed explanations of various touch sensor mechanisms, including piezocapacitive, piezoresistive, surface capacitive, piezoelectric, triboelectric, and triboresistive. It also discusses the challenges of minimizing humidity sensitivity, improving resilience, and suppressing unwanted electrochemical reactions, along with future directions for touch sensors. image
