    Tattoo Ink–Related Infections — Awareness, Diagnosis, Reporting, and Prevention

    As tattoo's become more and more popular among people of all ages, it's no surprise that we're discovering that there's more risk to the process that most may be aware of. Besides from the obvious pain, The process off tattooing is very dangerous, as it leads you exposed and suseptibal to infection or disease, such as nontuberculous mycobacterial infections. Good hygine and sterical equipment has always been enforced and regulated by the FDA, but it seems that the problem lies mainly somewhere else. At no fault of the given parlor, they could be injecting their customers with contaminated ink that was damaged before distribution even. The sicknesses that result from this are unpleasent, hard to indetify as they could be confused with allergies, and even harder to treat. It is important that the risk of tattoos is known and that people are aware of the consequences before marking yourself with something for the rest of your life and potentially endangering your health.

    Exposure to UV (Ultra-Violet) light is a major cause of melanoma. The degree/sevarity of the cancer can vary, however, based on the skin type of the person and the amount of exposure to these harmful rays. The damage that this causes is not just skin deep, but even further. It can cause genetic mutations and alterations as well. Certian parts of the body are more suseptable to the damage than others too. For example, face, shoulders and arms are more likely to be at risk than say the stomach or back, because they are more vulnerable to the sun and exposed daily for the most part. These problems can also be passed down through genetics. If a parent before you suffered from this, you are more likely to be at risk than someone without this in their DNA.

    Muscle membrane repair and inflammatory attack in dysferlinopathy

    Renzhi Han
    Skeletal Muscle 2011, 1:10

    When damage occurs in the plasma membrane, Toxins such as calcium and oxidants are able to enter the cell. They then are able to inflame and damage the cell and potentially kill it, while also endangering the neighboring cells. A rapid membrane repair response that is conserved in many different types of cells to restore the plasma membrane integrity has been shown in recent studies. However, defects in this reparation have resulted in pathological troubles in various body tissues, maily the skeletal and heart. In conclusion, continuous release of substance from cells with defective membrane repair sends "help" and "danger" signals to the immune system and can cause further damage to the said tissues.

    FLEXIBILITY IS NOT RELATED TO STRETCH-INDUCED DEFICITS IN FORCE OR POWER

    From traditional studies and beliefs, it is widly believed that lack of static stretching before any exciercise or athletic activity could greatly hinder your performance. However, there are there are few studies looking into the effect of long term stretch training on stretch reduction. It is commonly thought that people with a wider range of motion in their musicles would experience less stretch-induced deficits. After testing, the results showed that a lesser amount of stretching incurred significant impairments for knee extension and flexion, drop jump contact time and countermovement jump height. These results showed no significant relationship between ROM and stretch-induced deficits. There was alson no major resultant on those who tested with the streting for a longer, more intense session for days.

    The Respiratory Muscles

    Charis Roussos, M.D., and Peter T. Macklem, M.D.

    N Engl J Med 1982; 307:786-797September 23, 1982



    The respiratory system is composed of two main parts. First, the lungs, which is a gas-exchanging organ. there's also a pump that ventilates the lungs. This pump is made up of the chest wall, respiratory muscles, and nerves to trigger the actions. Both parts of the system are crutial and necesscary for proper function. Whether it be from disease or malfunction, failure to operacte correctly and efficently usually result in hypoxemia with normocapnia or hypocapnia. Failure of the pump alone would lead to what is most commonly known as hyperventilation.
