Minimally invasive procedureMinimally invasive procedures (also known as minimally invasive surgeries) encompass surgical techniques that limit the size of incisions needed, thereby reducing wound healing time, associated pain, and risk of infection. Surgery by definition is invasive and many operations requiring incisions of some size are referred to as open surgery. Incisions made during open surgery can sometimes leave large wounds that may be painful and take a long time to heal.
Focal adhesionIn cell biology, focal adhesions (also cell–matrix adhesions or FAs) are large macromolecular assemblies through which mechanical force and regulatory signals are transmitted between the extracellular matrix (ECM) and an interacting cell. More precisely, focal adhesions are the sub-cellular structures that mediate the regulatory effects (i.e., signaling events) of a cell in response to ECM adhesion. Focal adhesions serve as the mechanical linkages to the ECM, and as a biochemical signaling hub to concentrate and direct numerous signaling proteins at sites of integrin binding and clustering.
Polyéthylène glycolOn appelle polyéthylène glycol ou PEG des polyéthers linéaires de masse molaire inférieure à fabriqués à partir de monomères d'éthylène glycol. Leurs propriétés hydrosolubles et liposolubles en font des produits utilisés dans un grand nombre d'industries (médical, cosmétique). On les appelle également macrogol dans le domaine médical. On a l'habitude d'indiquer la masse molaire moyenne du polymère après le nom, par exemple PEG-2000 (). Lorsque leur masse molaire est supérieure à , on les appelle plus communément poly(oxyde d'éthylène) ou poly(oxyéthylène).
Wound bed preparationWound bed preparation (WBP) is a systematic approach to wound management by identifying and removing barriers to healing. The concept was originally developed in plastic surgery. During the year 2000, the concept was applied to systematizing the treatment of chronic wounds. The 2000 proposals recommended that wound management address the identifiable impediments to healing in order to achieve more successful outcomes. Three publications appeared that year that focused on the concept of managing the healing processes of a wound exudate, bioburden and devitalized tissue.
Loose connective tissueLoose connective tissue, also known as areolar tissue, is a cellular connective tissue with thin and relatively sparse collagen fibers. Its ground substance occupies more volume than the fibers do. It has a viscous to gel-like consistency and plays an important role in the diffusion of oxygen and nutrients from the capillaries that course through this connective tissue as well as in the diffusion of carbon dioxide and metabolic wastes back to the vessels.
Self-replicationSelf-replication is any behavior of a dynamical system that yields construction of an identical or similar copy of itself. Biological cells, given suitable environments, reproduce by cell division. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Biological viruses can replicate, but only by commandeering the reproductive machinery of cells through a process of infection. Harmful prion proteins can replicate by converting normal proteins into rogue forms.
Auto-assemblage moléculairedroite|400px|thumb|Un exemple de molécules se liant par liaisons d'hydrogène. L'auto-assemblage moléculaire est le processus par lequel des molécules soi-montant adoptent un agencement sans la direction d'une source extérieure. En général, le terme fait référence à l'auto-assemblage intermoléculaire alors que l'auto-assemblage intramoléculaire prend plus communément le nom de pliage ou de repliement dans le cas de protéines.
Chimie macromoléculairePolymer chemistry is a sub-discipline of chemistry that focuses on the structures of chemicals, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry, analytical chemistry, and physical chemistry. Many materials have polymeric structures, from fully inorganic metals and ceramics to DNA and other biological molecules.
Solubilitévignette|La réaction de précipitation, effectuée à partir d'une solution ou d'une suspension, forme un précipité et un liquide surnageant, observés ici dans un tube à essai. La solubilité est la capacité d'une substance, appelée soluté, à se dissoudre dans une autre substance, appelée solvant, pour former un mélange homogène appelé solution. La dissolution désigne ce processus. En thermodynamique, la solubilité massique est une grandeur physique notée s désignant la concentration massique maximale du soluté dans le solvant, à une température donnée.
Triéthylène glycolLe triéthylène glycol est un composé chimique de formule . Il s'agit d'un liquide visqueux incolore — il fond à et bout à — utilisé comme plastifiant pour vinyle, comme désinfectant, comme absorbeur d'humidité pour le gaz naturel et dans les systèmes de climatisation, ou encore comme additif pour fluides hydrauliques et liquides de frein. Le triéthylène glycol est miscible avec l'eau et soluble dans l'éthanol, l'acétone, l'acide acétique, le glycérol, la pyridine et les aldéhydes.
