摘要:
The present disclosure provides a cultivation method of morels and belongs to the technical field of cultivation of edible fungi. After nutrient contents that can be metabolized and utilized by morel mycelia are scientifically matched, sterilization treatment of exogenous nutrients is eliminated, and the exogenous nutrients are directly compressed for forming. Formed exogenous nutrient blocks and spawn is sowed and covered with soil, so as to realize a potential difference between “rich” and “poor” nutrients in a physical space. When the spawn germinate to form a mycelium network, the mycelia will enter a nutrient-rich exogenous nutrient area, secrete various extracellular enzymes to decompose and utilize these exogenous nutrient blocks, and transport them to a nutrient-poor mycelium network for storage, so as to complete nutrient assimilation and absorption, and reserve energy for later sexual reproduction.

The present disclosure provides a use of a novel environment-friendly agricultural chemical, and belongs to the field of agricultural chemicals. It is found in the present disclosure that methyl 4-hydroxyphenylacetate may be used for controlling plants and preparing herbicides. The methyl 4-hydroxyphenylacetate in the present disclosure has a use concentration greater than 150 mmol/L. The herbicide is prepared by using the methyl 4-hydroxyphenylacetate as an active ingredient in the present disclosure has a good controlling and killing effect on perennial herbs or Half-shrubby plants, especially Eupatorium adenophorum, and has low toxicity, no harm, and no solvent residues after use.
摘要:
A low-molecular-weight fucosylated glycosaminoglycan (aTFG) containing 2,5-anhydrated talose, alditol, glycosylamine or N-substituted glycosylamine monosaccharide composition thereof, preparation method thereof, pharmaceutical compositions containing the aTFG, and use thereof for preventing and/or treating thrombotic diseases are provided. The aTFG has potent anticoagulant activity targeting at intrinsic coagulation factor Xase, and inhibiting thrombogenesis, and therefore can be used as drugs for preventing and/or treating cardiovascular and cerebrovascular diseases.
摘要:
Provided are a low-molecular-weight fucosylated glycosaminoglycan derivative (derivative of Low molecular weight Fucosylated Glycosaminoglycan, dLFG) having anticoagulant activity, a preparation method thereof, a pharmaceutical composition comprising dLFG or a pharmaceutically acceptable salt thereof, and the use of dLFG and pharmaceutical composition thereof in preparing medicine for treating thrombotic diseases.
摘要:
The invention relates to a use of an urushiol compound (code named GQ-5) in preparation of pharmaceutical compositions for inhibiting Smad3 phosphorylation. We verify that GQ-5 inhibited the interaction of Smad3 with TGF-β type I receptor (TβRI), inhibited subsequent phosphorylation of Smad3, reduced nuclear translocation of Smads complex, and suppressed the transcription of major fibrotic genes such as α-smooth muscle actin (α-SMA), collagen I and fibronectin. Therefore, GQ-5 could be a potent and selective inhibitor of TGF-β1-induced Smad3 phosphorylation, and be used to prepare pharmaceutical compositions for inhibiting Smad3 phosphorylation.

Some embodiments of the disclosure provide an application method of a CRISPR/Cas12a gene editing system in the gene editing of Physcomitrella patens (P. patens). According to an embodiment, the application method includes the following steps: 1) constructing a Cas12a protease expression vector by ligating a Cas12a-protease-encoding nucleotide sequence with nuclear localization signals at both ends to a plasmid pAct-Cas9 and initiating expression by a pActin promoter; 2) constructing a gRNA expression vector by ligating a gRNA to a plasmid pU6-sgRNA, and initiating expression by a PpU6 promoter; and 3) transforming P. patens by using the Cas12a protease expression vector, the gRNA expression vector, and the plasmid for resistance expression obtain a mutant plant through screening for resistance.
