In the village of Kwa-al, located in central Nigeria, 36% of the children tested positive for Schistosomiasis. The Carter Center estimates that 200 million people in 74 different countries are infected with Schistosomiasis. It is a parasite transmitted by snails living in slow moving water and usually affects school age children. The parasite is absorbed through the skin when exposed to contaminated water and can cause poor growth and development, bladder dysfunction and kidney disease. Schistosomiasis can be treated with a single dose of the drug Praziquantel. Here children who had just received a dose of Praziquantel in an effort to control the parasite are again swimming in contaminated water. Wednesday October 20, 2004. ©Vanessa Vick

C-reactive protein (CRP) is an ancient highly conserved molecule and a member of the pentraxin family of proteins. CRP is secreted by the liver in response to a variety of inflammatory cytokines. Levels of CRP increase very rapidly in response to trauma, inflammation, and infection and decrease just as rapidly with the resolution of the condition. Thus, the measurement of CRP is widely used to monitor various inflammatory states. CRP binds to damaged tissue, to nuclear antigens and to certain pathogenic organisms in a calcium-dependent manner.
The function of CRP is felt to be related to its role in the innate immune system. Similar to immunoglobulin (Ig)G, it activates complement, binds to Fc receptors and acts as an opsonin for various pathogens. Interaction of CRP with Fc receptors leads to the generation of pro-inflammatory cytokines that enhance the inflammatory response. Unlike IgG, which specifically recognizes distinct antigenic epitopes, CRP recognizes altered self and foreign molecules based on pattern recognition. Thus, CRP is though to act as a surveillance molecule for altered self and certain pathogens. This recognition provides early defense and leads to a proinflammatory signal and activation of the humoural, adaptive immune system.
Principle of CRP Test
The C-Reactive Protein test is based on the principle of the latex agglutination. When latex particles complexed human anti-CRP are mixed with a patient’s serum containing C reactive proteins, an visible agglutination reaction will take place within 2 minutes.
Uses of CRP Test
CRP may be used to detect or monitor significant inflammation in an individual who is suspected of having an acute condition, such as serious bacterial infection like sepsis, a fungal infection and Pelvic inflammatory disease (PID).
The CRP test is useful in monitoring people with chronic inflammatory conditions to detect flare-ups and/or to determine if treatment is effective. Some examples include Inflammatory bowel disease, some forms of arthritis and Autoimmune diseases, such as lupus or vasculitis.
The determination of the CRP-level is useful to monitor the therapy.
It is done to check for infection after surgery. CRP levels normally rise within 2 to 6 hours of surgery and then go down by the third day after surgery. If CRP levels stay elevated 3 days after surgery, an infection may be present.
A shot using the regular popup flash on the Nikon D90 (left), then with the Lightscoop diffuser attached. Pretty nice. I'm thinking a lot more indoor shots are in my future.
Testing out the basic astrophotography setup. This was taken from in the city and there was a bit of atmospheric disturbance but it's something to build on.

Prepping for a Qumu live broadcast to London at the end of the month. The good folks at NewTek loaned me a Tricaster860 for the test. It is a little bit overkill for my needs. Somewhat like needing a Yugo and borrowing a Ferrari. An incredible piece of technology. I will miss it when I take it back.
The last time I went on Test Track was in 2000. I don't remember much about it besides that I didn't like it that much. The refurbished version seems better. To help the time pass by, they added this "design your own car" section where I took it upon myself to design a horrible car that, if all is right with the world, will never exist.
