The present invention belongs to the technical field of animal semen cryopreservation, and discloses a portable liquid nitrogen fumigation programmed freezer, which includes a freezing box. The bottom of the freezing box is connected with an equipment box and a storage box. The equipment box and the storage box are connected side by side on the base. The top of the equipment box and the storage box is provided with a first buckle to fix the freezing box on the top of the equipment box and the storage box. The bottom of the base is provided with walking wheels, and the top of the freezing box is hinged with a top cover through a hinge shaft; by setting an independent freezing box and an equipment box, and arranging the controller box outside the freezing box, the freezing chamber is isolated from the electronic control system and the mechanical transmission system, which is convenient for reducing the technical difficulty of equipment manufacturing, prolonging the service life of the equipment, facilitating packaging and transportation, facilitating assembly and combination when needed, facilitating transportation to different animal resource farms, implementing on-site freezing of straw semen, and obtaining a high temperature of about 4 °C by controlling the opening degree of the top cover to avoid difficulties in obtaining high temperature caused entirely by the increase in the distance from the liquid nitrogen surface and other dilemmas.

The present invention discloses a method for generative prediction of blood biochemical and blood routine indexes in rat toxicology experiments on chemicals based on multimodal fusion and GANs models, including: S1, obtaining the SMILES formula of the chemical to be predicted; S2, obtaining data of three modalities of the chemical, including molecular structure, biological activity, and batch key molecular docking activities; S3, combining the data of the three modalities with the dosing dose and dosing time, and inputting them into a pre-trained alternative rat experiment prediction model; S4, the output result of the alternative rat experiment prediction model is the generative prediction values of 25 indexes of blood biochemistry and blood routine at the set dosing dose and set dosing time of the chemical from the data source. The present invention greatly improves the prediction accuracy and efficiency, can effectively assist in the toxicity identification and management of new chemicals, effectively saves the time and energy of experimental personnel, and also saves animal resources and improves animal welfare.

The present application provides a kind of intertidal zone beach benthic animal intelligent identification and density monitoring method and device, in the target area of investigation light beach, multiple independent sample quadrats are laid according to random way, video is collected using unmanned aerial vehicle and is pretreated;In uniform video environment, the identification and spatial scale calibration of sample quadrat are carried out synchronously, and the target identification of beach benthic animal is carried out;The actual beach area corresponding to the video picture is determined according to the sample quadrat identification result, and the representative quantity and biological density of the species are calculated based on the identification result of target species using median statistical method.The non-contact, automatic and high-precision monitoring of intertidal zone beach benthic animal is realized through the cooperative application of unmanned aerial vehicle aerial photography and improved YOLO identification model, the interference of artificial investigation is reduced, the stability, accuracy and monitoring efficiency of density estimation are improved, and it is suitable for large-scale, high-frequency investigation and monitoring of intertidal zone beach benthic animal resources.

The invention discloses an injectable gel loaded with a periplaneta americana glycoprotein microsphere. The glycoprotein comes from medicine residues left after alcohol extraction of periplaneta americana, the microspheres are prepared by adopting an emulsification-two-step crosslinking method, and cationic guar gum is used as a gel matrix. The prepared microspheres are uniformly dispersed into a gel solution through ultrasonic waves before gel forming, and hydrogen bond cross-linked gel is formed under the action of hydrochloric acid and sodium hydroxide. The related preparation process is simple, low in cost and convenient to popularize, and full utilization and high-value development of periplaneta americana medicinal animal resources are realized. The obtained injectable gel is stable in overall state, has good indexes such as mechanical property, rheological property, self-healing property and injectability, and also has degradability. The periplaneta americana glycoprotein existing in the microsphere state can show the slow release characteristic and the long-acting activity; and after being further prepared into an injectable gel form, the injection gel is convenient for clinical use and even realizes multi-functionalization of the whole system.

The invention discloses a pure natural environment-friendly laminate with 50-100% of animal bones and a manufacturing method of the pure natural environment-friendly laminate. The preparation method comprises the following steps: firstly, cleaning bones and carapace of human edible animals, degreasing the bones (adopting food-grade n-hexane for extraction), optionally adding pure natural tissues such as bamboo fibers, mixing, carrying out hot press molding, and finally, carrying out post-treatment by using natural materials. Related animal resources are utilized, use of industrial chemical reagents is avoided, the manufactured laminate is environmentally friendly and good in strength and toughness, has sound insulation and heat insulation performance, solves the environment and health problems of existing plates, and can be applied to the fields of building decoration, furniture manufacturing and the like.
