Cancer de l'ovaireLe est une forme de cancer affectant un ovaire. Il se développe généralement à partir du revêtement de surface des ovaires. La forme la plus fréquente est le carcinome épithélial de l'ovaire. Les formes rares, comme les tumeurs germinales de l'ovaire ou les tumeurs borderline , justifient d'une prise en charge spécifique. Le cancer de l'ovaire est en général de mauvais pronostic car découvert souvent tardivement. L'ovaire est situé dans le petit bassin et une lésion tumorale peut se développer lentement sans signes cliniques.
Cancer des voies aérodigestives supérieuresUn cancer des voies aérodigestives supérieures (ou improprement cancer de la tête et du cou) est un cancer localisé au niveau des voies aérodigestives supérieures, ce qui regroupe les sinus, les fosses nasales, le pharynx (composé du nasopharynx, de l'oropharynx et de l'hypopharynx), la cavité buccale et le larynx. Outre la localisation, ce type de cancer partage, pour un certain nombre, plusieurs éléments : survenue liée à la consommation importante d'alcool et de tabac, type histologique de carcinome épidermoïde, exploration médicale ORL stéréotypée.
Breast cancer awarenessBreast cancer awareness is an effort to raise awareness and reduce the stigma of breast cancer through education about screening, symptoms, and treatment. Supporters hope that greater knowledge will lead to earlier detection of breast cancer, which is associated with higher long-term survival rates, and that money raised for breast cancer will produce a reliable, permanent cure. Breast cancer advocacy and awareness efforts are a type of health advocacy. Breast cancer advocates raise funds and lobby for better care, more knowledge, and more patient empowerment.
NeurotrophineNeurotrophins are a family of proteins that induce the survival, development, and function of neurons. They belong to a class of growth factors, secreted proteins that can signal particular cells to survive, differentiate, or grow. Growth factors such as neurotrophins that promote the survival of neurons are known as neurotrophic factors. Neurotrophic factors are secreted by target tissue and act by preventing the associated neuron from initiating programmed cell death – allowing the neurons to survive.
Épuration des eauxthumb|Station d'épuration des eaux à Aguas Corrientes, en Uruguay. L’épuration des eaux est un ensemble de techniques qui consistent à purifier l'eau soit pour réutiliser ou recycler les eaux usées dans le milieu naturel, soit pour transformer les eaux naturelles en eau potable. La fin du marque l'essor des réseaux d'égouttage et d'assainissement en France (courant hygiéniste, rénovation de Paris du baron Haussman). Il s'agit d'éloigner les eaux usées des habitations et des lieux de vie.
Skin infectionA skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes. They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), and acute bacterial SSSIs (ABSSSIs). They are distinguished from dermatitis (inflammation of the skin), although skin infections can result in skin inflammation.
Water treatmentWater treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
Pathogenic bacteriaPathogenic bacteria are bacteria that can cause disease. This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. By contrast, several thousand species are part of the gut flora present in the digestive tract.
Souris« Souris » est un nom du vocabulaire courant qui peut désigner toutes sortes de mammifères rongeurs ayant généralement une petite taille, un museau pointu, des oreilles rondes, un pelage gris-brun et une queue relativement longue. Autrement dit, ce terme ne correspond pas à un niveau précis de la classification scientifique des espèces. Il s'agit d'un nom vernaculaire dont le sens est ambigu en biologie, car il est applicable seulement à une partie des espèces classées dans l'ordre des Rodentia.
Secondary treatmentSecondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option. A "primary treatment" step often precedes secondary treatment, whereby physical phase separation is used to remove settleable solids.
