Surface Doping to Suppress Iodine Ion Migration for Stable FAPbI Perovskite Quantum Dot Solar Cells.

Small

December 2024

Dalian National Laboratory for Clean Energy, iChEM, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, 457 Zhongshan Road, Dalian, 116023, P. R. China.

Formamidine lead iodide (FAPbI) quantum dots (QDs) have attracted great attention as a new generation of photovoltaic material due to their long carrier diffusion length, benign ambient stability, and light-harvesting ability. However, its large surface area with inherent thermodynamic instability and highly defective ionic termination are still major obstacles to fabricating high-performance devices. Herein, a metallic ion dopant is developed to post-treat FAPbI QDs immediately after their fabrication by using a metal-glutamate salt solution.

College of Materials Science and Engineering, Xi'an University of Architecture and Technology, Xi'an 710055, PR China. Electronic address:

NH-MIL-125 with abundant porosity and specific interactions with CO molecules, has been demonstrate great potential in the field of photocatalytic CO reduction. However, conventional NH-MIL-125 and their composites much lower CO photoreduction efficiency in aerobic environments because of the O competition. To circumvent the issue, this study modifies NH-MIL-125 through crystal facet engineering to enhance its selective CO adsorption and photocatalytic efficiency in the environment of impurity CO.

In this study, composite biscuits were produced by combining wheat flour (WF) with different proportions of malted pearl millet (MPM) flour (8%, 16%, 24%, and 32%) and orange peel (OP) flour (2%, 4%, 6%, and 8%), using 100% WF as a control. The investigation covered the functional properties, viscosity, and thermal properties of the flours, along with the proximate composition, antioxidant, physical properties, color attributes, and microbial quality of the composite biscuits. As MPM and OP flour (OPF) contents increased, water absorption capacity, dispersibility, and foaming power increased, while the viscosities of both hot and cold pastes decreased.

Physicochemical properties and fermentation characteristics of a novel polysaccharide degraded from residues polysaccharide.

Food Chem X

December 2024

College of Life Sciences, Engineering Research Center of Bioreactor and Pharmaceutical Development, Ministry of Education, Jilin Agricultural University, Changchun 130118, Jilin, PR China.

() residues polysaccharide (FVRP) is a high molecular weight polysaccharide with diverse bioactivities extracted from residues (FVR). However, high molecular weight polysaccharides have been shown to face significant challenges in crossing the cell membrane barrier, thereby limiting their absorption and application in the body. Therefore, an ultrasonic-assisted HO-Fe method was employed for the first time to degrade FVRP, resulting in the production of a new polysaccharide, FVRPF.

December 2024

Department of Anesthesiology and Pain Medicine, Hubei Key Laboratory of Geriatric Anesthesia and Perioperative Brain Health, and Wuhan Clinical Research Center for Geriatric Anesthesia, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430030, China.

Oxidative stress is believed to play critical pathophysiological roles in ischemic brain injury, and the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway is recognized as the most crucial endogenous antioxidant stress damage route. Some research have demonstrated that Nrf2 play critical roles in oxidative stress after ischemic stroke, but the underlying mechanism are not fully elucidated. This study reveals that Nrf2 is modified by SUMOylation and identifies Sentrin/SUMO-specific protease 6 (SENP6) as a negative regulator of Nrf2 SUMOylation.

Squamous cell carcinomas (SCC) are often preceded by potentially malignant precursor lesions, most of which remain benign. The terminal exhaustion phenotypes of effector T-cells and the accumulation of myeloid-derived suppressor cells (MDSC) have been thoroughly characterized in established SCC. However, it is unclear what precancerous lesions harbor a bona fide high risk for malignant transformation and how precancerous epithelial dysplasia drives the immune system to the point of no return.

Background: The multi-biological barriers present in the inflammatory microenvironment severely limit the targeted aggregation of anti-inflammatory drugs in the lesion area. However, conventional responsive drug carriers inevitably come into contact with several pro-responsive stimulatory mediators simultaneously, leading to premature drug release and loss of most therapeutic effects. Breaking through the multi-level barriers of the inflammatory microenvironment is essential to improve the enrichment and bioavailability of drugs.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most challenging types of cancer with little or no response to immune checkpoint inhibitors (ICIs). Photodynamic therapy (PDT) has been shown to ablate tumors and induce an immune response. In our study, we investigated the effect of photodynamic therapy (PDT), using the photosensitizer Bremachlorin, in its ability to reduce tumor burden and to sensitize immunologically T-cell high and T-cell low murine PDAC tumors to the ICI that blocks programmed cell death-1 (PD-1) immune checkpoint.

Introduction: Self-determination theory (SDT) highlights the importance of satisfying people's basic psychological needs (BPN) (autonomy, competence and relatedness) in order to ensure their personal growth and wellbeing. In this regard, sport and physical activity (PA) have been shown to offer significant health benefits, particularly in the case of people with intellectual disability (ID), among whom the benefits are even more noticeable owing to their low levels of PA, sedentary lifestyle, limited opportunities to exercise, and consequently lower quality of life. The aim of this study is to assess the impact of the Más Que Tenis ("More Than Just Tennis") inclusive recreational sports programme on the satisfaction of BPN among athletes with ID, taking into account factors such as age, gender and type of activity.
