Research Review Article Evidence-Based Use of Pulsed Electromagnetic Field Therapy in Clinical Plastic Surgery Berish Strauch‚ MD; Charles Herman‚ MD; Richard Dabb‚ MD; Louis J. Ignarro‚ PhD; and Arthur A. Pilla‚ PhD Background: The initial development of pulsed electromagnetic field (PEMF) therapy and its evolution over the last century for use in clinical surgery has been slow‚ primarily because of lack of scientifically-derived‚ evidence-based knowledge of the mechanism of action.

Frog Skeletal Muscle The aim of this experiment is to explore the basic physiological principles of skeletal muscle using the isolated frog (Rana pipiens or Xenopus laevis) gastrocnemius muscle. Students will dissect a double-pithed frog. Then‚ they will connect the muscle to the Force Transducer to measure twitch recruitment‚ effect of stretch‚ muscle summation‚ muscle tetanus‚ and muscle fatigue. Written by staff of ADInstruments.

genetically modified animal‚ a fluorescent zebra fish. It is made and then advertised by Yorktown technologies. It is a genetically modified organism (or GMO). The fish got the fluorescence from a red fluorescent protein from a sea anemone under the myosin light peptide 2 genes of zebra fish. The new green colored fish got is color from the extracted Green Fluorescent Protein that is taken from one jellyfish species called Aequorea victoria. These fish are beneficial for a lot of things including the

Sea urchins are members of the phylum Echinodermata‚ which also includes sea stars‚ sea cucumbers‚ brittle stars‚ and crinoids. Like other echinoderms‚ they have five-fold symmetry (called pentamerism) and move by means of hundreds of tiny‚ transparent‚ adhesive "tube feet". The symmetry is not obvious in the living animal‚ but is easily visible in the dried test. Echinodermate means "spiny skin" in Greek. Specifically‚ the term "sea urchin" refers to the "regular echinoids"‚ which are symmetrical

Streptococcal proteins display molecular mimicry recognized by the immune system‚ especially bacterial M-proteins and human cardiac antigens such as myosin and valvular endothelium. Antimyosin antibody recognizes laminin‚ an extracellular matrix alpha-helix coiled protein‚ which is part of the valve basement membrane structure. The valves most affected by rheumatic fever‚ in order‚ are the mitral‚ aortic

Muscle cells are different from other cells‚ because they contain more protein than other cells‚ specifically actin and myosin proteins. C. What is the sarcolemma? It is the plasma membrane in muscles. Exercise 2: Organization of Skeletal Muscle Cells into Muscles Observations Sketch the skeletal muscle cross section. Identify the muscle

From a young age we are taught to eat a balanced diet full of nutrients which in the body are broken down into individual ions and molecules. Of these ions and molecules‚ the most important are Calcium (Ca+2)‚ Sodium (Na+)‚ Potassium (K+) and ATP which are primarily derived in from what we eat but also the body synthesizes on its own. Ions play an important role due to their relative electrical charge. These important ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb
