.... of oculocutaneous albinism, and five types of ocular albinism. Newer laboratory research studying DNA has shown that there are numerous types of changes in the genes of those with albinism, including within families. The most common types of oculocutaneous albinism are called "ty-negative" and "ty-positive". Persons with ty-negative albinism have no melanin pigmentation, and more difficulty with vision. Those with ty-positive albinism have very slight pigmentation, and generally less severe visual difficulties. Tests were done on the hair roots of individuals with albinism, to tell these types of albinism apart. However, these hair tests cannot identify types of albini ....

.... spring. Melatonin is the hormone that controls not only when we feel sleepy, but the rate at which we age, when we go through puberty, and how well our immune systems fend off diseases. Being set in the middle of our brains, the pineal gland has no direct access to sunlight. Our eyes send it a message of how much sunlight they see, and when it's dark. The sunlight prohibits the gland from producing melatonin, so at night, when there's no sun, the sleep-inducing hormone is released into our bodies. Because of the pineal gland and melatonin, humans have known to sleep at night and wake during the day since long before the age of alarm clocks. Humans don't produc ....

.... and falling under one genus, ‘Filovirus'. "The Ebola virus and Marburg virus are the two known members of the Filovirus family" (Journal of the American Medical Association 273: 1748). Marburg is a relative of the Ebola virus. The four strains of Ebola are Ebola Zaire, Ebola Sudan, Ebola Reston, and Ebola Tai. Each is named after the geographical location in which it was discovered. These filoviruses cause hemorrhagic fever, which is actually what kill victims of the Ebola virus. Hemorrhagic fever as defined in Mosby's Medical, Nursing, and Allied Health Dictionary as, a group of viral aerosol infections, characterized by fever, chills, headache, malaise ....

.... have some but not all of the same features and symptoms. PWS is a birth defect. A defect in the hypothalamus, a region of the brain, is suspected to be the cause.The hypothalamus determines hunger and satiety.They can’t fell satiety,so they always have a urge to eat.Some PWS cases are so out of control thay will eat bottlecaps,glass,pencils,garbage,bugs,dogfood, and anything else they can stuff in their mouths. "The ingenuity and determination of PWS children in surreptitiously obtaining edibles is almost legendary and belies their cognitive defects. Serial weighing may be the only way to discover whether such a child is, in fact, stealing food"(Finey,1983). PWS occur ....

.... in the 21 years since was legalized. This slaughter of innocent human beings must stop. Using as a means of birth control should be illegal. These babies that are being killed are not just worthless fetuses. They are tiny little humans beings. A tiny six week old unborn baby has forty six chromosomes in every cell which is the scientifically verifiable human genetic code and he has brain waves that can be measured. The end of human life can be defined as the moment when brain waves cease but many ignore the scientific evidence of brain waves in unborn babies. As small as seven weeks old a baby can swim freely in the amniotic sack. At nine weeks, the baby is extremely a ....

.... a long time because there are so many possibilities, since Africa is in the tropics. Another way that humans can get Ebola is by eating an infected animal or drinking the milk of an infected animal. Ebola is spread from human to human by contact with infected blood, infected body fluids, or through sexual contact. Even after a person recovers completely from Ebola, it may stay in the semen for up to seven weeks. In the African outbreaks it has also been transmitted by the reuse of needles because the health care systems are so under financed. Ebola wasn't thought to be an airborne virus, but recent studies by the US Army Medical Research Institute of Infectious D ....

.... to 4 to 6 weeks. Chronic bronchitis is produced by other chronic problem: sinusitis, smoking, TB, etc. The Bronchi becomes thick, inelastic, and accumulate mucus and pus in lower part of lungs instead of bringing discharges up and out. The result is chronic cough, shortness of breath, sometimes spasm, and frequent infection. In acute bronchitis, the basic symptoms are a head cold, fever and chills, running nose, aching muscles and possibly back pains. This is soon followed by the obvious persistent cough. At first the cough is dry and racking and eventually becomes phlegmy. The persistent cough is worse at night than during the day, and when the person breathes in s ....

.... uterine contractions. If there is no fertilization of the egg, high levels of estrogen and progesterone activate and negative feedback inhibiting the release of FSH and LH. Without FSH and LH the corpus luteum deteriorates causing uterine contraction to expell the endometrium. However, if the egg is fertilized the level of estrogen and progesterone must remain high so the endometrium is not shed. The outer layer of the egg mass(blastocyct) produces a hormone(HCG) to maintain the corpus luteum for the first 3 months of pregnancy so it can provide high levels of estrogen and progesterone. After the third month the placenta provides enough estrogen and progesterone to main ....
