Fluorine (F) is the most electronegative element in the periodic table, a pale yellow, highly reactive gas. It is found in nature as the fluoride ion, typically combined with other elements in minerals. Fluorine is not found free in nature because of its high reactivity. The element is produced industrially by electrolysis of potassium hydrogen fluoride (KHF2) dissolved in anhydrous hydrofluoric acid (HF). Fluorine is used in the production of many important compounds, including polytetrafluoroethylene (PTFE), also known as Teflon, which is used in non-stick cookware and other applications. It is also used in the production of pharmaceuticals, refrigerants, and other chemicals. Fluorine is important because of its unique properties, including its high reactivity and its ability to form strong bonds with other elements. It is studied in many scientific fields, including chemistry, physics, and materials science. Fluorine is essential for human health, playing a role in bone and tooth formation. However, excessive fluoride intake can lead to health issues. In dentistry, fluoride is used to prevent tooth decay. Fluorine is also used in the production of nuclear weapons and rocket propellants.'

Fluorine imparts a variety of properties to certain medicines, including an enhanced absorption rate and improved drug transport across the blood-brain barrier. Fluorine substitution may increase a molecule's lipophilicity, thereby enabling its diffusion across cell membranes to enhance bioavailability.

| Down Syndrome A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE.

They may present at any age, but are most frequent in the third to fifth decades, with an earlier incidence peak in the first decade. Histologically, these tumors are encapsulated, relatively avascular, and tend to form cysts and microcalcifications. Neoplastic cells tend to have small round nuclei surrounded by unstained nuclei. The tumors may vary from well-differentiated to highly anaplastic forms.
