Penetrating traumaPenetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment. The penetrating object may remain in the tissues, come back out the path it entered, or pass through the full thickness of the tissues and exit from another area.
Protéine fluorescente vertevignette|Aequorea victoria. La protéine fluorescente verte (souvent abrégé GFP, de l'anglais « Green Fluorescent Protein ») est une protéine ayant la propriété d'émettre une fluorescence de couleur verte. Issue d'une méduse (Aequorea victoria), cette protéine est intrinsèquement fluorescente sous l'action d'une enzyme, l'aequoréine, une luciférase qui agit en présence de calcium. Son gène peut être fusionné in-vitro au gène d'une protéine que l'on souhaite étudier.
Bioidentical hormone replacement therapyBioidentical hormone replacement therapy (BHRT), also known as bioidentical hormone therapy (BHT) or natural hormone therapy, is the use of hormones that are identical on a molecular level with endogenous hormones in hormone replacement therapy. It may also be combined with blood and saliva testing of hormone levels, and the use of pharmacy compounding to obtain hormones in an effort to reach a targeted level of hormones in the body. A number of claims by some proponents of BHT have not been confirmed through scientific testing.
PlaceboA placebo (pləˈsiːboʊ ) is a substance or treatment which is designed to have no therapeutic value. Common placebos include inert tablets (like sugar pills), inert injections (like saline), sham surgery, and other procedures. In general, placebos can affect how patients perceive their condition and encourage the body's chemical processes for relieving pain and a few other symptoms, but have no impact on the disease itself.
Épiderme (botanique)vignette|Vue au MEB de la surface supérieure d'une feuille de Nicotiana alata montrant la surface de l'épiderme, les trichomes et les stomates (visibles en pleine résolution). En botanique, l'épiderme est le tissu végétal superficiel formant une couche protectrice continue à la surface des parties aériennes d'une plante, tant que les structures sous-jacentes sont primaires (jeune tige, feuille, fleur). Le tissu superficiel primaire des racines est appelé rhizoderme ou assise pilifère.
