  • How To Keep Yourself Healthy, Factors In The Aging Of Your Health
    By: Dr. Mital John | - The aging process is for the greater part no mystery anymore. It consists for a great part of daily damages done on the macroscopic, tissue, cellular and genetic levels. These add up as the years are passing. These damages have specific causes like oxidating agents, sun beams, mechanical wear and tear, psychological stress, lack of some nutritional components and too much of others, like fat.
    Another component of aging is the reduction of the telomere chains at the chromosome ends, as each ...

  • Baby Gender Selection
    By: ChoiceMethod | - CHOICE Method

    In 1961, Koltzoff and V Schroder, Russian scientists, concluded that the sperms with different gender chromosomes were drawn by an anode or cathode. Sperm containing X chromosome were attracted to a positive charge while sperm containing the Y chromosome were attracted to the negative charge.

    Later scientists discovered that the ovum membrane also carried an electric charge. The charge on the ovum membrane was not fixed but alternated from positive to neut ...

  • The Unique Foot Of Down Syndrome
    By: Brandt R Gibson DPM | - Some of the friendliest people I know have a special condition called Trisomy 21 or Down syndrome. In these individuals many skin, bony, muscle and joint conditions exist due to abnormal collagen development. One of the types of collagen (Type VI) is encoded by a gene on chromosome 21. The resulting effect is increased joint laxity or looseness of the ligaments that attach bone to bone or tendons that attach muscles to bone (hypotonia of muscles). The ligamentous laxity and hypotonia wil ...
