Objective: To find out whether attractive images of the male and female sex organ during sex is feasible and to deed out whether former and current ideas about the frame during sexual intercourse and during female intimate physiological condition are based on assumptions or on facts. Thirteen experiments were performed with eight couples and three single women. Methods: Magnetic resonance imaging was used to examination the animate being sexual event and the male and egg-producing sex organ during coitus. Results: The images obtained showed that during sexual activity in the “missionary position” the penis has the spatiality of a misreckoning and 1/3 of its section consists of the base of the penis.

Depending on the energy, intimately all of them, but generally, the higher the frequency, the solon dangerous. UV, X-Rays, and da gamma radiation are all generally harmful. Starting with the nigh patently dangerous, gamma rays are the great frequence and nearly energetic form of light. They're useful for medical and bone imaging, but if they interact with your DNA, they can cause cancer.
Nanoparticle penetration of human skin - a double-edged sword
) Engineered nanoparticles are at the position of the speedily developing field of nanomedicine. Their unique size-dependent properties, of which ocular and attractable effects are the most in use for begotten applications, makes them suited for a wide range of medicine applications such as cell labeling and targeting, tissue engineering, drug manner of speaking and drug targeting, charismatic timber imaging, inquisitory of DNA structure, tumor conclusion via heating (hyperthermia), and detection and analysis of biomolecules such as proteins or pathogens. some of these applications can also be bespoke to target skin to service in the early designation of a skin disease, which then could also be treated via nanocarriers.
