Abstract: Provided is a method for reducing methane production in animal stomachs by adding melatonin to gastric juice of the animal or feeding the animal with melatonin. In the method of the present disclosure, 10?7 mol/L to 10?3 mol/L of melatonin can reduce the methane production from the in vitro gastric fermentation fluid, feeding melatonin of 8.0 to 35.0 mg/kg/day can reduce the methane production from the animal respiration from day 7 of feeding melatonin. The method of the present disclosure can reduce greenhouse gas emissions of animals, control environmental pollution and realize low-carbon farming.

Abstract: A porous, self-sustaining body useful as a scaffold for bone grafting is provided. The scaffold comprises a carbonaceous matrix comprising a continuous phase having a surface and defining a plurality of open spaces throughout the matrix. The internal and external surfaces of the matrix are coated with a layer or film selected from the group consisting of osteogenic materials, therapeutic agents, and combinations thereof. The porous body comprises organic materials and is substantially free of metals. Methods of making and using the porous self-sustaining body are also provided, along with kits for facilitating the same.

Abstract: A metal bone supporter for medical bone substitute including a supporter and a connector component which are functionally and structurally designed according to anatomical data and biomechanical data. The titanium alloy powders in the device are able to be scanned, melted and molded through electron beams, to form a cylinder with the strength and elastic modulus similar to cancellous bones of the human body. The supporter component is a porotic spongy body structure with threads on an end, and porous structure forms a rough surface. The connector component is made with a smooth surface and a dense solid mass inside, a thread on an end, and is connected to the supporter component as a removable body. The porous structure enables bone growth, and the device has a high surface friction coefficient, and has a stable structure and mechanical properties are similar to bones.
