Pain is an important symptom of abdominal disease. Its position and characteristics give important clues to the likely causes. The types of pains previously described tend to have characteristic positions which can help point to their origin.By far the most common cause of abdominal pain in the general population is irritable bowel syndrome, or IBS.
Lithium fluoride, the lithium salt of hydrofluoric acid, may be used as an adjuvant in antibiotic therapy. Lithium fluoride is useful for the development of nanostructures and nanolayers.
The end-result is that lithium is isoelectronic with helium and fluorine is isoelectronic with neon. Electrostatic interaction occurs between the two resulting ions, but typically aggregation is not limited to two of them. Instead, aggregation into a whole lattice held together by ionic bonding is the result.
