The causes of gender dysphoria are not yet fully understood. A personâs biological sex is determined by two chromosomes â one from the mother, and one from the father.5 Early in pregnancy, all fetuses are female because the X chromosome (which is inherited from the mother) is the only active chromosome.
Paralytic shellfish poisoning (PSP) is one of the four recognized syndromes of shellfish poisoning, which share some common features and are primarily associated with bivalve mollusks (such as mussels, clams, oysters and scallops).he toxins responsible for most shellfish poisonings are water-insoluble, heat and acid-stable, and ordinary cooking methods do not eliminate the toxins. The principal toxin responsible for PSP is saxitoxin.
Name of the Organism: Various Shellfish-Associated. Shellfish poisoning is caused by a group of toxins elaborated by planktonic algae (dinoflagellates, in most cases) upon which the shellfish feed.The toxins are accumulated and sometimes metabolized by the shellfish. The 20 toxins responsible for paralytic shellfish poisonings (PSP) are all derivatives of saxitoxin.Diarrheic shellfish poisoning (DSP) is presumably caused by a group of high molecular weight polyethers, including okadaic acid, the dinophysis toxins, the pectenotoxins, and yessotoxin.ame of the Organism: Various Shellfish-Associated.
