As the temperature rises, the insulation is mostly rolled up and covered on the roof. The heat preservation of some vegetable farmers is exposed to the sun, and they are allowed to expose to the sun and rain, which greatly accelerates their aging speed and seriously affects the service life of the heat preservation quilt. Therefore, after the insulation is rolled up, it must be protected. The waterproofness of rainwater is an important indicator for evaluating thermal insulation quilts. At present, most thermal insulation quilts have good waterproof performance. However, some thermal insulation quilts of some materials are not waterproof. It is easy to breed mold after entering the water and affect the service life. Therefore, before the insulation is rolled up, it should be dried in the sun, covered tightly with a film that is not damaged, and the insulation should be cleaned around to prevent the water from soaking the insulation from the bottom. Once the cover is blown away by the wind and the rainwater is soaked in the insulation, it should be dried in time and re-covered tightly. Sunscreen insulation is mostly black or dark brown, easy to absorb light and generate heat. In the spring, the light is strong. If there is no shading with a covering and only the film is wrapped, the dark insulation will be released slowly after absorbing heat. The internal temperature can even rise to above 70 ℃, which obviously accelerates its aging rate. Therefore, after the insulation is rolled up, it should be covered with waterproof material such as film first, and then covered with non-woven fabric and other shading materials. Windproof and windy It is often accompanied by windy weather in spring, and the rolled insulation is easily blown away by the wind or the roof. Vegetable growers should check the fixing of the insulation blanket in time to avoid being blown away by the wind. Especially after the strong wind, it is necessary to check the preservation of the insulation in time, and solve the problem in time.

Palatin Technologies Inc. (NYSE: PT-141) announced today that it has shown positive results in a Phase I clinical trial of pT-141 for the treatment of sexual dysfunction in normal premenopausal women.
The trial included 32 healthy female volunteers and evaluated their response to pT-141 and placebo in response to visual stimuli. Pt-141 was found to be safe and resulted in a significantly greater improvement in vaginal blood flow than placebo users (P< 0.05).

Such antibiotics first affect the outer membrane of sensitive bacteria. Drug ring part of polypeptide amino and lipopolysaccharide in the outer membrane 2 valence cations combining site to produce electrostatic interaction, destroy the integrity of the outer membrane damage, fatty acid part of drugs to penetrate the outer membrane, thus increase the permeability of cell size, lead to intracytoplasmic phosphate, nucleosides and other small molecules to escape, straight die cause cell dysfunction. Gram-positive bacteria do not respond to such antibiotics because they have a thick cell wall that prevents drugs from entering the bacteria.
