notes ♥ _____________________________________________________________________________________________The Clark electrode is an electrode that measures oxygen on a catalytic platinum surface using the net reaction:
O2 + 4 e− + 2 H2O → 4 OH−
The Clark type electrode uses a silver/platnium-electrodes immersed in an electolyte solution. An oxygen-permeable membrane, which encloses the electrode, enables the measurement of oxygen exchange between the test sample and the electrolyte solution. As the potential increases, oxygen is reduced to hydrogen peroxide when electrons are donated to oxygen. The current flow is stoichiometrically related to the oxygen consumed at the electrode.
notes ♥ _____________________________________________________________________________________________The nutrient called Vitamin D is a group of fat-soluble prohormones. Exogenous Vitamin D undergoes two hydroxylation reactions to be activated in the body. The term vitamin D refers generally to all forms of Vitamin D, Vitamin D metabolites and Vitamin D analogues.
Vitamin D is a nutrient found in some foods that is needed for health and to maintain strong bones. Vitamin D does so by helping the body absorb calcium (one of bone’s main building blocks) from food and supplements. When we get too little vitamin D our bones may become soft, thin, and brittle, a condition known as Rickets in children and Osteomalacia in adults.
Vitamin D is important to the body in many other ways as well. Muscles need it to move, for example, nerves need it to carry messages between the brain and every body part, and the immune system needs vitamin D to fight off invading bacteria and viruses. Together with Calcium, Vitamin D also helps protect older adults from osteoporosis. Vitamin D is found in cells throughout the body.

Canadian scientists experiment seemed to refute truism, says Globe and Mail. Researchers in Toronto are going to create a cure for breast cancer - an inexpensive analogue of the drug “Herceptin” - genetically-modified tobacco leaves.

For each blood type, one temper ^^
My experiment to found the blood type~
notes ♥ _____________________________________________________________________________________________- Northern Blot : mRNA
- Southern Blot DNA
- Western Blot : proteins
- Eastern Blot : lipids
Il s’agit de mettre en contact une bactérie avec de l’eau oxygénée (H2O2). S’il y a une dégagement gazeux (O2), c’est qu’il y a présence d’une catalase (enzyme).
La plupart des bactéries Gram - possède une catalase (E.coli).
notes ♥ _____________________________________________________________________________________________- Enterobacteria family
- Present on most terrestrial animals (but they are not ill)
- Dangerous for Human Beings = Typhoid fever : 200 000 deaths/ yr (world wild).
