muscle fibers to form a tendon. The aponeuroses tissues are the forms broad fibrous sheets that attach to the coverings of adjacent muscles. The epimysium lies beneath the fascia‚ the perimysium extends into the structure of the muscle‚ where muscle cells separate into fascicles. Endomysium separates individual muscles fibers. Skeletal muscle fibers contract in response to stimulation and then relax when the stimulation ends. Threadlike structures called myofibrils run lengthwise throughout the muscle

For example‚ in diagnosing myocardial infection‚ electrophoresis is used to separate isoenzymes of lactase dehydrogenase and creatine kinase. Electrophoresis can also be used to separate blood proteins for accurate diagnosis of protein impaired metabolism such as patient with abnormal haemoglobin. Apart from that‚ electrophoresis can also be used as a method to separate and purify proteins. MATERIALS AND REAGENTS: 1. Electrophoresis

The purpose of this paper is to review the literature surrounding the safety of red blood cell (RBC) transfusions‚ which comes under standard seven of the National Safety and Quality in Health Service Standards (ACSQHC‚ 2012). It will touch on the complications of RBC transfusion‚ when to transfuse‚ the management of blood loss and the impact of RBC transfusion on critically

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
