| 1 | Debris Flow Hazard Assessment Based on Support Vector Machine显示文摘Seven factors, including the maximum volume of once flow , occurrence frequency of debris flow , watershed area , main channel length , watershed relative height difference , valley incision density and the length ratio of sediment supplement are chosen as evaluation factors of debris flow hazard degree. Using support vector machine (SVM) theory, we selected 259 basic data of 37 debris flow channels in Yunnan Province as learning samples in this study. We create a debris flow hazard assessment model based on SVM. The model was validated though instance applications and showed encouraging results. | YUAN Lifeng 1, 2 , ZHANG Youshui 3 1.

| 2 | Nb2C MXene-Functionalized Scaffolds Enables Osteosarcoma Phototherapy and Angiogenesis/Osteogenesis of Bone Defects显示文摘Early surgical resection and chemotherapy of bone cancer are commonly used in the treatment of bone tumor,but it is still highly challenging to prevent recurrence and fill the bone defect caused by the resection site.In this work,we report a rational integration of photonic-responsive two-dimensional(2D)ultrathin niobium carbide(Nb2C)MXene nanosheets(NSs)into the 3D-printed bone-mimetic scaffolds(NBGS)for osteosarcoma treatment.The integrated 2D Nb2C-MXene NSs feature specific photonic response in the second near-infrared(NIR-II)biowindow with high tissue-penetrating depth,making it highly efficient in killing bone cancer cells.Importantly,Nb-based species released by the biodegradation of Nb2C MXene can obviously promote the neogenesis and migration of blood vessels in the defect site,which can transport more oxygen,vitamins and energy around the bone defect for the reparative process,and gather more immune cells around the defect site to accelerate the degradation of NBGS.The degradation of NBGS provides sufficient space for the bone remodeling.Besides,calcium and phosphate released during the degradation of the scaffold can promote the mineralization of new bone tissue.The intrinsic multifunctionality of killing bone tumor cell and promoting angiogenesis and bone regeneration makes the engineered Nb2C MXeneintegrated composite scaffolds a distinctive implanting biomaterial on the efficient treatment of bone tumor. | Junhui Yin Shanshan Pan Xiang Guo Youshui Gao Daoyu Zhu Qianhao Yang Junjie Gao Changqing Zhang Yu Chen | 2021 | Nano-Micro Letters2021，13，2： | 5 |

| 9 | Interactive effect of hot air roasting processes on the sensory property,allergenicity,and oil extraction of sesame(Sesamum indicum L.)seeds显示文摘Sesame seeds are a healthy food ingredient and an oil crop for sesame oil production;however,it has recently been recognized as an essential allergenic food by FAO/WHO.This research investigated the relationship between the hot air roasting process(at 120,150,and 180℃ for 10,20,and 30 min)and several quality attributes of sesame seeds since roasting is the key process for preparing sesame seeds for both consumption and oil production.The hot air process followed the central composite design.The changes of sesame in terms of color,sensory properties(odor,texture,color,and taste),allergenicity caused by oleosins(ses i 4 and ses i 5),as well as oil extraction and quality were monitored using a colorimeter,sensory evaluation panelists,ELISA,as well as oil yield and acid value,respectively.Roasting temperature influenced the product quality more than roasting time,although the two processing parameters significantly interacted with each other(P<0.001).Sensory evaluation indicated medium roasting generated attractive flavor,order,appearance,and crispy texture.Allergenicity was high in sesame seeds after high-temperature roasting,according to IgE binding capacity test.Sesame oil extraction was favored by high-temperature roasting,which,however,adversely affected the oil quality.The optimal roasting conditions were 150.5℃ for 15 min for optimized sesame seeds quality in terms of sensory properties and allergenicity,while roasting at 158℃ for 10 min was optimal for sesame oil production.The finding will benefit the sesame seed industry. | Shudong He Tiange Pan Zuoyong Zhang Yanni Wu Hanju Sun Youshui Ma Yi Zhang | 2023 | Grain & Oil Science and Technology2023，6，2： | 0 |
| 10 | Intercellular mitochondrial transfer as a means of tissue revitalization显示文摘As the crucial powerhouse for cell metabolism and tissue survival,the mitochondrion frequently undergoes morphological or positional changes when responding to various stresses and energy demands.In addition to intracellular changes,mitochondria can also be transferred intercellularly.Besides restoring stressed cells and damaged tissues due to mitochondrial dysfunction,the intercellular mitochondrial transfer also occurs under physiological conditions.In this review,the phenomenon of mitochondrial transfer is described according to its function under both physiological and pathological conditions,including tissue homeostasis,damaged tissue repair,tumor progression,and immunoregulation.Then,the mechanisms that contribute to this process are summarized,such as the trigger factors and transfer routes.Furthermore,various perspectives are explored to better understand the mysteries of cell-cell mitochondrial trafficking.In addition,potential therapeutic strategies for mitochondria-targeted application to rescue tissue damage and degeneration,as well as the inhibition of tumor progression,are discussed. | Delin Liu Youshui Gao Jiao Liu Yigang Huang Junhui Yin Yuyao Feng Linjing Shi Bruno PMeloni Changqing Zhang Minghao Zheng Junjie Gao | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 0 |
