Chinese scientists have expanded the application of optical probes and in vivo fluorescence imaging
Tyrosinase is an important marker of melanoma and is closely related to diseases such as albinism and Parkinson's disease. Therefore, the development of optical sensing and imaging analysis methods for tyrosinase is of great significance for the diagnosis of related diseases. The traditional detection tyrosinase fluorescent probes all contain 4-hydroxybenzene units, which are interfered by reactive oxygen species during imaging analysis of biological systems such as cells, thereby seriously affecting the accuracy of the detection results. Recently, with the strong support of the National Natural Science Foundation of China, the Ministry of Science and Technology, and the Chinese Academy of Sciences, the research team proposed a new tyrosinase recognition unit (3-hydroxybenzyl), which was combined with a stable semi-paritrin. The near-infrared optical probe (pictured) suitable for imaging cells and live zebrafish effectively solves the problem of interference of existing fluorescent probes by reactive oxygen species.

European Type Wire Rope Hoist is a type of lifting equipment that is used to lift and move heavy loads in various industries such as construction, manufacturing, and mining. This type of hoist is designed and manufactured according to the European standard EN 13157, which ensures the highest level of safety, reliability, and performance.
One of the key features of the European Standard Wire Rope Hoist is its safety features. These hoists are equipped with various safety devices such as overload protection, emergency stop buttons, and limit switches, which ensure that the hoist stops automatically when it reaches its maximum load capacity or encounters any other safety hazards.
The lifting capacity from 1 ton to 60 ton, lifting height from 3 m to 60 m as per customer's different demands, widely are used in Overhead Crane, Gantry Crane, Jib Crane , Port Crane.

The optical probe with excellent performance is the material basis for constructing optical sensing and living imaging analysis methods with high sensitivity and high spatial-temporal resolution, and its development has been receiving attention. The Ma Huimin Research Group of the Laboratory of Analytical Chemistry of the Institute of Chemistry, Chinese Academy of Sciences has been engaged in research in this area for a long time and has achieved a series of results.
(Angew. Chem. Int. Ed., 2012, 51, 6432; Anal. Chem., 2014, 86, 6115; Angew.
Chem. Int. Ed., 2014, 53, 10916; Chem. Sci., 2016, 7, 788; Chem. Sci., 2016, 7,

The European Standard Wire Rope Hoist consists of a motorized drum that is connected to a wire rope. The wire rope is wound around the drum, and as the drum rotates, the rope moves up or down, lifting or lowering the load. The hoist also includes a lifting mechanism, which can be electric or manual, and a control system that allows the operator to control the hoist's movements.
In conclusion, the European Standard Wire Rope Hoist is a reliable and safe lifting equipment that is widely used in various industries. Its adherence to the European standard ensures that it meets the highest level of safety, reliability, and performance, making it an ideal choice for any lifting application.
