This invention belongs to the field of genetic engineering technology, and more specifically, relates to a drought-responsive gene in larch trees. LgLEA10 Proteins and their applications. This invention provides a larch drought response gene. LgLEA10 The nucleotide sequence of the protein is shown in SEQ ID NO.1, and the amino acid sequence of the protein it expresses is shown in SEQ ID NO.2. This invention is the first to demonstrate that the Dahurian larch... LgLEA10 The gene is a regulatory gene for the larch's response to drought. This invention demonstrates through experiments that... LgLEA10 Gene overexpression can enhance the drought resistance of larch by significantly increasing the activity of antioxidant enzymes and osmotic regulators. This discovery provides important genetic resources and theoretical basis for breeding new larch varieties with strong drought resistance.

The application discloses application of leptin in preparation of a medicine for promoting hair growth, and belongs to the technical field of biological medicines. The leptin provided in the application is expressed in hair matrix cells of a growing hair follicle, activates a JAK-STAT signal path, and induces continuous proliferation of hair matrix cells, so as to promote the hair follicle to enter the growing period in advance, prolong the time length of the growing period of the hair follicle, promote differentiation of the hair matrix cells into keratinocytes, maintain continuous growth of the hair shaft, and further prolong the length of the hair shaft.

The present application relates to the technical field of bone cell static pressure loading, and discloses a bone cell static pressure loading device with multi-mode pressure control, which comprises a pressurizing mechanism and a PLC control assembly, wherein the pressurizing mechanism comprises a high-pressure gas storage tank, a gas pressure reducing valve, a connecting pipe A, a gas flow control valve, a pressure conversion bin, a piston, a connecting pipe B, a connecting frame and a pressure sensor; the gas pressure reducing valve is installed on the high-pressure gas storage tank; the connecting pipe A is connected to the high-pressure gas storage tank; and the gas flow control valve is installed on the connecting pipe A. The gas flow control valve, the pressure conversion bin, the pressure sensor and the PLC control assembly can realize the loading of various pressure modes such as static pressure, periodic pressure and simulated physiological pressure waveform, can accurately simulate the mechanical environment that bone cells bear under different physiological and pathological conditions, effectively reduces experimental errors, and improves the reliability and repeatability of experimental results.

This invention discloses a method for alleviating cadmium stress on duckweed using ethyl caffeate. With industrial development, cadmium pollution in water bodies seriously threatens the ecosystem and human health, and traditional remediation methods have shortcomings. Although duckweed has the potential for water body remediation, cadmium stress inhibits its growth. This invention, through concentration gradient experiments, determines the maximum Cd concentration that duckweed can withstand. 2+ The optimal concentration of ethyl caffeate for alleviating cadmium stress is 200 μmol, with a concentration of 10 μmol. Adding 200 μmol of ethyl caffeate per 100 ml of cadmium-contaminated water significantly promotes duckweed growth, increases leaf number, fresh weight, and root length, enhances antioxidant enzyme content, reduces MDA content, increases chlorophyll content, and strengthens photosynthesis. It also significantly reduces cadmium accumulation in duckweed, achieving efficient bioremediation of cadmium pollution in water bodies. This method is simple to operate, low in cost, and environmentally friendly, showing broad application prospects in the field of water pollution control.
