Blaschkos Lines and Invisible Stripes on Human Skin

Blaschko's Lines and Invisible Stripes on Human Skin Unless you have one of a number of skin diseases, you may not realize you have stripes, much like those on a tiger! Ordinarily, the stripes are invisible, though you can see them if you shine an ultraviolet or black light over your body. What Are Blaschko's Lines? The  Lines of Blaschko or  Blaschkos lines make V-shaped stripes down your back, u-shapes  on your chest and stomach, simple stripes on your arms and legs, and waves on your head. The stripes were first described by German  Alfred Blaschko in 1901. Blaschko was a dermatologist who observed pigmented patterns in people with certain skin diseases. The patterns are also visible in people with chimerism. A chimera begins as two cells that have different DNA from each other. As these cells grow and divide, they contain slightly different instructions on how to produce proteins, including pigments. The lines dont follow blood vessels, nerves, or lymphatic vessels, believed instead to reflect the migration of embryonic skin cells. Under ordinary conditions, skin cells are programmed to produce the same amount of pigment as each other, so the stripes arent noticeable. The slight differences are more obvious under the higher energy of ultraviolet light. Other animals besides humans display Blaschko lines, including cats and dogs. How To See Your Human Stripes Whether or not you can view your own human stripes depends on your natural skin pigmentation and the type of UV light you use. Not all black lights are sufficiently energetic to make the lines visible. If you want to try to view your own stripes. youll need a dark room and a mirror. Shine the black light over exposed skin and look for the pattern. Conditions Where Human Stripes Are Visible Several skin disorders may follow Blaschkos lines, making them visible. These conditions may be inherited or acquired. Sometimes the stripes are visible throughout life. Under other conditions, they appear and then fade. While its possible for the whole body to be affected, many times the lines only appear on a single limb or region. Here are some examples of skin conditions associated with Blaschkos lines. Congenital Skin Disorders linear sebaceous naevus (lifelong)unilateral naevoid telangiectasia (lifelong) Acquired Skin Disorders lichen striatus (one to two years)linear psoriasis  (one to two years)linear scleroderma Genetic Skin Disorders Conradi-Hunermann syndromeMenke’s syndrome How Are Blaschko's Lines Treated? If Blaschkos lines were simply stripes, treatment might be as simple as applying make-up or a drug to fade the pigment. Sometimes Blaschkos lines only affect skin pigmentation. However, the marks associated with skin conditions may present as dermatitis, with papules and vesicles. In some cases, corticosteroids may improve skin health. Treatments that reduce physical and emotional stress and address the underlying cause of the condition may also help.

American Torture Techniques Against Detainees

American Torture Techniques Against Detainees The U.S. government has been accused of using torture-lite or moderate physical pressure against detainees, persons held in custody for political reasons, typically because they pose a distinct threat to the U.S. or possess information crucial to American security. In practical terms, what does this mean? Palestinian Hanging This form of torture is sometimes  referred to as Palestinian hanging due to its use by the Israeli government against Palestinians. It involves binding the prisoners hands behind his back. After fatigue sets in, the prisoner will inevitably fall forward, putting full body weight on his shoulders and impairing breathing. If the prisoner is not released,  death by crucifixion  may eventually result. Such was the fate of U.S. prisoner  Manadel al-Jamadi  in 2003. Psychological Torture The number one criterion for torture-lite is that it must leave no physical marks. Whether U.S. officials are threatening to execute a prisoners family or falsely claiming that the leader of his terror cell is dead, a steady diet of misinformation and threats can be effective.   Sensory Deprivation Its remarkably easy for prisoners to lose track of time when theyre locked up in cells. Sensory deprivation involves removing all noise and light sources as well. Guantanamo prisoners  were additionally bound, blindfolded and wore earmuffs. Whether prisoners subjected to long-term sensory deprivation can still tell fiction from reality is a matter of some debate.   Starvation and Thirst Maslows hierarchy of needs identifies basic physical needs as the most fundamental, more so than religion, political ideology or community. A prisoner may be given just enough food and water to survive. It may take as long as a week before he appears physically thinner, but his life will come to revolve around a quest for food and he may be more inclined to divulge information in exchange for food and water.   Sleep Deprivation Studies have shown that missing a nights sleep temporarily drains 10 points from a persons IQ. Consistent sleep deprivation  through harassment, exposure to bright lights and exposure to loud, jarring music and recordings can drastically impair judgment and wear down resolve.   Waterboarding Water torture is one of the oldest and most common forms of torture. It arrived in the U.S. with the first colonists and has cropped up many times since then. Waterboarding  is its latest incarnation. It  involves  a prisoner being strapped down to a board then dunked in water. Hes brought back to the surface and the process is then repeated until his interrogator secures the information being sought.   Forced Standing Most common in the 1920s, forced standing involves prisoners standing in place, often overnight. In some cases, the prisoner may face a wall, standing with his arms extended and his  fingertips touching it.   Sweatboxes Sometimes referred to as a hot box or simply as the box, the prisoner is locked up in a small, hot room which, due to lack of ventilation, essentially functions as an oven. The prisoner is released when he cooperates. Long used as a form of torture in the U.S., it is particularly effective in the arid Middle East. Sexual Assault  and Humiliation Various forms of sexual assault and humiliation documented in U.S. prison camps  as forms of torture include forced nudity, forcible smearing of menstrual blood on prisoners faces, forced lap dances, forced transvestitism and forced homosexual acts on other prisoners.
