Oestridae
Oestridae is a family of parasitic flies commonly known as bottfly or warble fly. Oestridae are blood-feeding flies that infect various mammals, including birds, reptiles, and amphibians. They are known for their large size and distinctive, bulging eyes. These flies are also known for laying their eggs in the tissue of their host, where they can cause significant harm and discomfort.
Oestriol
Oestriol is a type of estrogen, a female sex hormone. It is one of the three major estrogen hormones in pregnant women, along with estradiol and estetrol.

It plays a crucial role in the development of the fetus and the preparation of the birth canal for childbirth.
Oestrogen
Oestrogen is a type of hormone that is produced by the ovaries in women and plays a crucial role in the development and regulation of the female reproductive system.

In addition, oestrogen helps to regulate the menstrual cycle and maintain the health of the vagina, cervix, and pelvic lining.

It is a term used to describe the condition of having high levels of estrogen in the blood, which can be caused by various factors such as hormonal imbalances, polycystic ovary syndrome (PCOS), or certain medications. Oestrogenism can also be used to describe the process of estrogen production and secretion by the ovaries during the menstrual cycle.
Oestrogens

Ofatumumab
Ofatumumab is a human monoclonal antibody that is used to treat certain types of non-Hodgkin's lymphoma, a type of blood cancer. It specifically targets and binds to a protein called CD20 on the surface of B cells, which are a type of white blood cell.
