    摘要: Biologically active 19-nor vitamin D analogs substituted at C-2 in the A-ring with an ethylidene group. These compounds have preferential activity on mobilising calcium from bone and either high or normal intestinal calcium transport activity which allows their in vivo administration for the treatment of metabolic bone diseases where bone loss is a major concern. These compounds are also characterised by high cell differentiation activity.

    摘要: Surface treated inorganic oxide pigments are provided wherein one or more of the ethylene glycol esters and diesters are applied to the surface of a base inorganic oxide pigment, for example, an anatase titanium dioxide pigment from the calciner of a conventional sulfate route process for making titanium dioxide pigments or especially a rutile titanium dioxide pigment from the oxidizer in a conventional chloride route process for making titanium dioxide pigments.
