Abstract

The present invention relates to the use of the overexpression of a Populus tomentosa strigolactone receptor PtoD14 gene in increasing a wood yield. By means of cloning a Populus tomentosa strigolactone receptor PtoD14 gene from wild-type Populus tomentosa and introducing the PtoD14 gene into Populus tomentosa plants by means of a genetic engineering method, a Populus tomentosa line with enhanced secondary development is obtained. The number of secondary xylem cell layers in 3-month-old PtoD14 transgenic Populus tomentosa is 8 to 21 layers more than that in 3-month-old non-transgenic common Populus tomentosa, which is of important significance for providing a high wood yield for the large-scale production of Populus tomentosa.

The present invention relates to vincamine derivatives, a preparation method therefor and a use thereof. The disclosed vincamine derivatives have the following advantages: (i) modification of the tail chain increases the lipid solubility of a vincamine compound without affecting the cerebral blood flow regulation of vincamine itself, which helps a carried drug to penetrate the blood-brain barrier and exert a brain protective effect, improving brain microcirculation disorders; (ii) the tertiary amine group in the parent nucleus structure of the vincamine derivatives has the property of being ionizable under acidic conditions, which can achieve efficient carrying and lysosomal escape of nucleic acid drugs by means of charge adsorption, thereby improving intracellular transport; and (iii) the vincamine derivatives inherit the various pharmacological activities inherent in vincamine and have a high degree of safety. The disclosed vincamine derivatives have good application prospects in brain-targeted delivery of drugs for treating brain diseases.

Abstract

Provided are a bombyx mori silk gland recombinant expression vector expressing a human epidermal growth factor, a preparation therefor, and an application thereof. The recombinant expression vector is formed by fusing an N-terminal domain and a C-terminal domain of a truncated silk fibroin heavy chain, an optimized human epidermal growth factor, and a bombyx mori nuclear polyhedrosis virus enhancer. A redundant part of an extra domain of an endogenous silk protein contained in a fusion protein is removed to the maximum extent, and on the basis of not affecting a genetic hybridization process of integrating a fusion exogenous target protein into a silk-based material, redundant post-translational modification of the fusion protein is eliminated as much as possible, thereby creating, by means of genetic hybridization, a functional silk material expressing a highly biologically active human epidermal growth factor, and providing a feasible solution for development of a novel highly biologically active silk-based material by means of an advanced biosynthesis platform represented by bombyx mori.

Abstract

An ultra-large torque, double-helix, double-overrunning, and integrated intelligent adaptive electric-drive front driving system, comprising a motor, a main shaft (1), a high-speed gear transmission mechanism, a low-speed gear transmission mechanism, and a front driving force output mechanism. The motor comprises a stator (15), a rotor (16), and a motor shaft assembly that is driven by the rotor (16); the front driving force output mechanism comprises a power output gear sleeve (34) and a differential (35); the power output gear sleeve (34) is rotatably sleeved on the main shaft (1). Compared with a traditional single row of overrunning clutches, multiple rows of overrunning clutches (6) can exponentially improve a load-carrying ability, and break though the carrying limit of a traditional overrunning clutch; the power output of front-engine front-wheel drive arrangement can be achieved by means of the design of the differential (35) and related components, and an entire transmission bridge is high in transmission efficiency; and therefore, in the case that a driving force is not cut off, gear-shifting transmission is adaptively and automatically performed along with the change of traveling resistance, thereby making the motor be always located on an efficient platform as much as possible, and greatly increasing an interval in which the motor efficiently operates.

The assembly comprises a transmission system, a shaft sleeve, and a third shaft. The transmission system comprises a low gear transmission mechanism, a reverse gear transmission mechanism, and an adaptive transmission assembly. The reverse gear mechanism has a transmission ratio I for transferring a reverse gear drive from a secondary shaft (12) to a main shaft (1). The low gear transmission mechanism has a transmission ratio II for transferring a low gear drive from the secondary shaft (12) to the main shaft (1). The transmission ratio I is greater than or equal to the transmission ratio II, and is used to output a power via a power outputting shaft. The invention utilizes the logical cooperation of two overrunning clutches, and configures appropriate transmission ratios, such that the overall structure is simple and compact, and reverse gear transmission shares a transmission path with low gear transmission and high-speed gear transmission without causing interference, thereby ensuring overall performance. The invention further utilizes a transmission shaft sleeve and provides an output via the third shaft, thereby being applicable to both electric vehicles and other variable-torque mechanical transmissions. In addition, a shaft sleeve-based output further ensures a large output torque.
