MindMap Gallery The ways and mechanisms of intercellular communication
The ways and mechanisms of intercellular communication mainly include electrical signaling, chemical signaling, and cytokine signaling. Electrical signals are rapidly transmitted through ion channels and gap junctions, enabling immediate responses between cells. Chemical signals are complex and involve the release and reception of neurotransmitters and hormones. Cytokines act as signaling molecules, playing a broad regulatory role in immune responses and intercellular communication.

Its properties include high elasticity and good ductility. Elastin has a wide range of sources and is commonly found in animal connective tissues such as skin and blood vessels. When using elastin in products, the amount and method of addition should be determined based on the characteristics of the product. It has many uses and can be added to skincare products to enhance skin elasticity and reduce wrinkles; Improving food texture and enhancing taste in the food industry; In the medical field, it can be used to make elastic scaffolds such as artificial blood vessels, providing support for tissue repair. Reasonable use can play its unique value.
This document aims to guide the proper use of proteins. Proteins are the fundamental substances that make up life and are essential for maintaining normal physiological functions in the body, with a wide variety of types. When using protein, daily diet is an important source, such as meat, eggs, etc., which are rich in high-quality protein. Measuring protein intake can be done using professional tools or methods to ensure that the intake meets the body's needs. When mixing protein powder, it should be prepared according to the recommended ratio, and the water temperature should not be too high to avoid damaging the protein activity. Different groups of people have different protein requirements, such as athletes and fitness enthusiasts who can increase their intake appropriately to meet the needs of body repair and muscle growth.
Introduction to Unsaturated Polyester Resin: It is an important thermosetting resin with various excellent properties. It has a wide range of applications and is used in the construction industry to produce fiberglass products such as doors, windows, decorative panels, etc; Used in the automotive industry for manufacturing body components. The advantages of use include simple molding process, low cost, and chemical corrosion resistance. However, it also faces challenges and limitations, such as relatively poor heat resistance and susceptibility to aging. During use, corresponding protective measures should be taken according to specific application scenarios, such as adding heat-resistant agents, antioxidants, etc., to extend their service life and fully leverage their advantages.
