Stem Cell Medicine ! These cells obtained from the blastocyst inner cell mass (outer cell mass is discarded) and have the capacity to develop into any tissue of the Human Being 210 ... Does the blastocyst? ... Yes!, A Human Being 5 days of age is between 50 and 150 cells, also called Stem Cells (Stem: Trunk). Also obtained amniotic fluid part (hematopoietic) and adult cells (via reprogramming) Science recognizes four types of stem cells: pluripotent cells that can develop into an Animal Ser (rational or irrational) Zygote example, pluripotent capable of developing into any tissue in the animal being so far are believed to capable of giving rise to a living being multipotent which can be transformed into a single type of tissue and UNIPOTENCIALES which can be transformed into a cell type anything else. WHAT IS THE ESSENCE OF THE PROBLEM? the root of this debate is to experiment with stem cells embryonic necessarily have to destroy a human embryo and then we ask What is the Identity and anthropological value of the human being at this early stage of their existence?, is justified to achieve a Greater Good (discovering new therapies) is taken to destroy a tiny human being?, perhaps we are resurrecting Niccolo Machiavelli in his book "The Prince" presents an argument similar to that of Hussein Obama "The Good comes from evil" or the "End justifies the means, perhaps not learn from history, when the late s. XIX human beings were bought, sold and bred like animals, perhaps we do not remember the humiliating Nazi experiments at Dachau and Auschwitz, the humiliation of African Americans in Alabama (Tuskegee) were experimental subjects in studies on the effects of syphilis, the effects of these experiments, which Obama has decided to fund tomorrow later recognize as humanity abominales.OTRAS Alternate with stem cells...

Headache Medicine What is headache or headache? Is the pain or discomfort that manifests limited to the cranial-brain area. (Do not include face, mouth or ear aches which are defined in the area of dental and ENT as an example of toothache and earache). Need not be the cause of cranial origin itself, or to have any special feature as it can locate the pain in the area described above. It occurs more frequently in females (18%) than males (6%). Uncommon in the elderly over 65 years if a female predominance PATHOPHYSIOLOGY the brain does not hurt, just the surrounding structures (vascular, meningeal, bone, teeth, and all those innervated by cranial or spinal nerves have receptors sensitive to pain. Any NOXA can to produce inflammation, vasodilation, compression, traction of these structures and increase or decrease in intracranial pressure can cause pain. It has identified the secondary oligaemia changes cerebral blood flow as part of the pathophysiological mechanism of migraine with aura. Second messengers such as nitric oxide and related peptide calcitonin gene as molecular mechanism responsible for the pain of migraine without aura. The sensitization of perivascular nerve receptors even without changes in the caliber of the vessel is capable of producing pain. Has been identified with the advent of the triptans that neurotransmitters may have regulatory effect of pain in migraine. Headache can be classified into: primary (no underlying injury) Secondary (with underlying injury) In primary headaches, the most important is migraine. DIAGNOSTIC CRITERIA FOR MIGRAINE WITHOUT AURA A-At least five attacks criteria B through D B-duration of 4-72 hours: with or without specific treatment.
