Abstract: Use of Fusarium brachygibbosum in the production of mycelial protein is provided, belonging to the technical field of microbial fermentation. It is proposed for the first time that the Fusarium brachygibbosum shows the characteristic of a high production yield of the mycelial protein that is significantly higher than that of other types of Fusarium reported so far. The mycelial protein produced by the Fusarium brachygibbosum is filamentous, flesh-colored, elastic, and toxin-free, serving as an ideal alternative protein. Therefore, the use provides a new means for industrial production of alternative proteins and a basis for the development of safe food. Moreover, the fermentation method in the use may greatly improve the production efficiency of the mycelial protein while reducing carbon emissions to protect the environment.

Abstract: A fiber-metal laminate having a honeycomb sandwich structure and a preparation method thereof are provided. Firstly, based on material reduction processing technology, a recessed polygonal structure is obtained according to a design trajectory, and an upper layer and a lower layer are closed to form a recessed honeycomb sandwich structure. Then, processed surfaces of the upper layer and the lower layer are chemically treated to passivate the processed surfaces, with the aim of increasing the adhesion between a fiber layer and the metal layers. Then, a viscous mixture is filled into the recessed structures of the metal layers to ensure the multifunctional characteristics and impact resistance of the fiber-metal laminate. Then, a fiber prepreg is laid between the upper layer and the lower layer to obtain a prefabricated fiber-metal laminate. Finally, the prefabricated fiber-metal laminate undergoes thermal curing treatment under pressure in a hot-pressing tank, thereby obtaining the fiber-metal laminate.

Abstract: Disclosed are markers for nasopharyngeal carcinoma (NPC) diagnosis and prognostic prediction, and use thereof. The INSL5 level in a plasma sample can be determined by means of ELISA. It was found that the INSL5 plasma level is significantly different between NPC patients and healthy population. The analysis results of a ROC curve show that an area under curve of INSL5 is 0.941, the critical value of the INSL5 level is 2.45 ng/ml, and the sensitivity and specificity thereof are 93.2% and 81.5% respectively. In the healthy cohort, the INSL5 level in EBV-positive plasma is significantly higher than that in EBV-negative plasma. The EBV-negative subjects comprise 34 healthy individuals and 72 NPC patients, and the INSL5 levels are observed to be significantly different between these two cohorts. The results of the ROC curve show that the area under curve of INSL5 is 0.988, the critical value of the INSL5 level is 2.25 ng/ml, and the sensitivity and specificity thereof are 97.2% and 91.2% respectively.
