Harlequin Ichthyosis Causes. The harlequin ichthyosis is known to be genetic in nature. The ABC 12 gene, which directs the protein production that is necessary to have a normal skin growth, is being mutated which leads to this severe skin disorder. It is a gene that is responsible for the transportation of lipid.
Boron (IPA: /ËbÉËrÉn/) is a chemical element with atomic number 5 and the chemical symbol B. A trivalent compound containing boron occurs abundantly in the ore borax. Boron is never found free in nature, and is a non-metal. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs' scale), and a weak conductor at room temperature.
Boric acid is the form of boron most likely to be encountered in drinking water, and can be lethal at high concentrations. Boiling, over-the-counter water filters (pitcher filters or faucet-attachment filters), and. water softeners are not effective at removing boron from water.
