The biological influences on health and illness are varied‚ and include genetics‚ infections‚ physical trauma‚ nutrition‚ hormones‚ and toxins. Many disorders have a biological basis in the form of an inherited genetic vulnerability or disposition. In schizophrenia‚ for example‚ if one monozygotic twin develops schizophrenia‚ there is at least a 60% chance the co-twin will also develop that disorder. When we consider that the prevalence of schizophrenia in the population is about 1%‚ it is clear

Stem Cell Research Adult stem cell research is providing opportunities to treat people with a various diseases and conditions. In 2010‚ a man’s ankle refused to heal so the doctor took bone marrow from the man’s pelvic bone with a needle‚ condensed it to about four teaspoons of rich red liquid‚ and injected that into his ankle. Four months later‚ the ankle was healed! Adult stem cells are found in all tissues of the growing human being and‚ according to latest reports‚ also have the potential
