‘Fighting Infection by Clonal Selection’ was created to commemorate the 50th anniversary of Burnet’s Clonal Selection Theory. The animation shows how clonal selection works during a bacterial infection of the throat. Frank Macfarlane Burnet was awarded the Nobel Prize in 1960 and is widely acknowledged as the founder of modern immunology.

Immunotherapy, an entirely new approach the employs the power of one’s own immune system, has shown to be effective in treating cancers that were fatal just five to 10 years ago. Stephen Schoenberger, PhD, co-director of the La Jolla Institute for Allergy and Immunology, discusses how tumors develop and how immunotherapy can help at a UC San Diego Health education event on Aug. 20, 2016.

Immunotherapy uses the body’s immune system to fight cancer. This animation explains three types of immunotherapy used to treat cancer: nonspecific immune stimulation, T-cell transfer therapy, and immune checkpoint inhibitors.

This video describes the Immune System and explains how it detects and attacks any foreign organism that enters the body.
We learn how the team in the MRC Centre for Transplantation at King’s College London have developed a way to harness the power of the Immune System after a transplant, whilst maintaining the body’s capacity to resist infectious diseases.
http://www.handwrittentutorials.com – This video gives a great overview of the cells and functions of the immune system in response to a pathogen. Both the innate and adaptive immune system are explored. This video is a good starting point for the other Handwritten Tutorials Immunology videos.

Hank calls in a friend to do his push ups for him today to explain how skeletal muscles work together to create and reverse movements. Hank and Claire also demonstrate the role size plays in motor units, the three phase cycle of muscle twitches, and how the strength and frequency of an impulse affects the strength and duration of a contraction. This episode also explains twitch summation, tetanus, and isotonic vs. isometric movements.

We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible.

Each time you take a step, 200 muscles work in unison to lift your foot, propel it forward, and set it down. It’s just one of the many thousands of tasks performed by the muscular system: this network of over 650 muscles covers the body and is the reason we can blink, smile, run, jump, and stand upright. So how does it work? Emma Bryce takes you into the body to find out.

Are you experiencing pain in your hip? Surgery is not always the answer, as Consultant Orthopaedic Surgeon Sebastian Dawson-Bowling explains in this video about hip injections.
Hip injections can help break the so-called ‘cycle of inflammation’ that can occur in the hip joint. Find out as Dawson-Bowling explains the types of hip injections available, who they’re suitable for, how long until hip injections take effect, and whether they are an alternative to hip replacement surgery.
About Sebastian Dawson-Bowling:
Sebastian Dawson-Bowling specialises in all aspects of lower limb surgery, most predominantly primary and revision hip and knee surgery.
His approach is centred around a firm belief that effective and empathetic communication with patients before surgery is a key element in both their short-term post-operative recovery, and in their long-term outcomes.
