CONT

The researchers who studied the German and Austrian patients ... had initially called the syndrome vaccine-induced prothrombotic immune thrombocytopenia; [two teams of researchers] now suggest a slightly simpler name: vaccine-induced immune thrombotic thrombocytopenia (VITT).

OBS

... the patients had unusual antibodies that trigger clotting reactions, which use up the body's platelets and can block blood vessels, leading to potentially deadly strokes or embolisms. The symptoms resemble a rare reaction to the drug heparin, called heparin-induced thrombocytopenia(HIT), in which the immune system makes antibodies to a complex of heparin and a protein called platelet factor 4(PF4), triggering platelets to form dangerous clots throughout the body.

Subject field(s)
  • Water Pollution
  • Algae
  • Marine Biology
  • Plant Biology
DEF

A proliferation of algae and/or higher aquatic plants in a body of water, often related to pollution.

DEF

A population explosion of microorganisms caused by the sudden availability of an essential substance. Phosphorous is a trigger factor in most aquatic systems.... Normally, ecologists call an aquatic population a bloom when there are 500 individuals of a species per milliliter of water.

OBS

In contexts, a descriptive expression like "heavy planktonic growth" may also be used.

DEF

Prolifération dans le milieu marin de micro-organismes végétaux dans des conditions hydroclimatiques favorables.

CONT

Les substances nutritives essentielles qui contribuent au développement exubérant des plantes aquatiques sont le phosphore et l'azote.

CONT

L'eutrophisation [...] se traduira donc par une brutale pullulation des végétaux planctoniques.

OBS

Nous n'avons pas retrouvé le terme «efflorescence» avec le sens donné par la définition ci-haut dans aucun des autres ouvrages à notre disposition (par ex. : Grand dict. encycl. Larousse, Dict. de l'environnement, de Frans C. Lemaire, Dict. usuel de l'environnement et de l'écologie, de R. Amavis, Dict. de l'eau, de l'Ass. québécoise des techniques de l'eau en collab. avec l'Office de la langue française). Il nous semble plus sage d'utiliser des expressions descriptives, comme «prolifération de micro-organismes végétaux» ou «développement exubérant de plantes aquatiques».
