In my opinion, the Diode laser is the next most useful Hair Removal light source and the most promising laser for hair removal.
These Diode systems deliver a longer wavelength than the Ruby (694 nm wavelength) and the Alexandrite (755 nm wavelength) lasers, but a shorter wavelength than the Nd: Yag (1064 nm wavelength) laser. This longer wavelength enables the light to penetrate deeper and is theoretically safer than shorter wavelength lasers because it can better avoid the melanin pigment in the skin's epidermis. The Diode laser's longer wavelength of light thereby penetrates into the hair follicle without causing as much epidermal injury as the Ruby or the Alexandrite. This fact allows the Diode laser to be used on darker skin colors than the Ruby or Alexandrite.
Because the Diode is the most recently introduced of the hair removal lasers, there is less experience and less long-term data in evaluating the Diode's claims. Newer Diode lasers such as the SLP 1000 are attempting to deliver longer durations of light (up to 1000 milliseconds) in order to protect the epidermal pigment thereby producing fewer side effects while producing better hair removal. There is just not enough experience with these newer machines, which have only been on the market since early 2001 (after having been re-modified)! These longer durations are designed to emulate the longer durations available for five years with the UltimateTM Light treatments. Surprisingly, the pulse durations on the Quantum, Aculight, or Vasculight systems have been made shorter, while lasers try to lengthen their durations to catch up with the UltimateTM Light pulsed light.
The 800 nm Diode at this time is probably capable of treating skin types 1, 2, 3; possibly 4, 5; and maybe 6. I would personally wait for more information and experience before recommending this machine. In my opinion, the Ultimate Lightâ„¢ pulsed light is the best overall machine for treating all six skin types based on safety and long term use (over nine years). However, for effective short-term treatment of skin types 1 to 4, I believe that the 808 nm Diode is satisfactory.
Accelerated industrialization of transgenic turfgrass
The Science and Technology Development Center of the Ministry of Education invited experts to form an appraisal committee to identify the results of the 863 project “Cultivating new germplasms of drought-tolerant and cold-resistant turfgrass using modern biotechnology†undertaken by the research group headed by Prof. Lin Zhongping of Peking University Life Sciences. Experts believe that the project team adhered to the close integration of research and development and formed a supporting research and development system for the upper, middle and lower reaches, which laid the foundation for the industrialization of transgenic turfgrass. The research has achieved important results in the breeding of drought-tolerant and cold-tolerant genes and transgenic turfgrass cultivation with independent intellectual property rights, and provides a practical and feasible technical system for the breeding of water-saving and long-green cold-season turfgrass varieties. And a number of valuable turfgrass new germplasm resources. In the same type of research, it has reached the leading domestic and international advanced level. It is understood that 8 new drought-tolerant and cold-tolerant functional genes have been cloned from the unique drought-tolerant and cold-tolerant species of China, Borrelia sinica, and Artemisia halodendron, and some gene control regions have been cloned and functionally studied. . Apply for 4 patents. The project team used the above genes to genetically transform several important cold-season turfgrasses and obtained more than 800 transgenic lines. After three consecutive years of field trials, 20 green periods were screened and drought tolerance and cold resistance were enhanced. The transgenic turfgrass strains, some of which strains are effective, have great potential for development and application. The project team conducted large-scale, multi-point field trials in Beijing and Shanxi, and initially studied the reproductive characteristics and cultivation techniques of different strains. Six trials of transgenic turfgrass and four environmental releases were approved.
