BACKGROUND Granuloma annulare is a granulomatous disease of unknown etiology. Various therapies have been tried in disseminated granuloma annulare (DGA), including corticosteroids, several variants of psoralen plus ultraviolet-A radiation, ultraviolet- A1 radiation, systemic retinoids, and dapsone, with variable success. We report a patient with recalcitrant DGA who was treated with fumaric aci...

Reduction in enteric methane (CH4) emissions from cattle can be achieved through use of feed additives, which often results increased emission hydrogen (H2). The objective this study was to investigate vitro effects a known sink, fumaric acid, combination with either 2 inhibitors, the macroalga Asparagopsis taxiformis or nitrate, on CH4 and H2 production, degradability, pH, redox potential. A c...

In this paper six new copoly(amide-imide)s (7a-f) were synthesized through the direct polycondensation reaction of N,N'-(4,4'-diphenylsulfone)bistrimellitimide (1) with 4,4'-diamino diphenylsulfone (2), 4,4'-diamino diphenylether (3), in the presence of adipic acid (4), fumaric acid (5) or terephthalic acid (6) as the second diacid in a medium consisting of N-methyl-2-pyrrolidone, triphenyl pho...
