The nuclear receptors dax1 and SF-1 play important and antagonistic roles in gonad differentiation in mammals. To study their potential functions in teleost fish, the full-length cDNAs of dax1 and SF-1 were cloned and characterized from spotted scat. Their expression patterns in adult tissues and juveniles treated with 17
Abstract. CaSn(OH)6 nanotubes were fabricated by sonochemical precipitation method at room temperature. A direct rolling process from nanosheets to nanotubes was expected for the synthesis of CaSn(OH)6 nanotubes. The transient CaSn(OH)6 nanosheets are formed as intermediates produced by the spontaneous self-assembly and transformation of amorphous colloid clusters. During the crystallizatio…
Abstract The selective hydrogenation of trans-4-phenyl-3-butene-2-one over Ru/g-Al2O3 stabilized with triphenylphosphine was investigated in the presence of diamine and base. It was found that 1,2-diphenylethylene-1,2-diamine (DPEN) was the best modifier among the investigated diamines. Both DPEN and KOH not only promoted the selectivity of the C O bond hydrogenation, but also accelerated the …
We report the first synthesis of elongated penta-branched gold nanocrystals with a shape resembling that of a star fruit but with sharp ends by a seeding growth approach. Cetyltrimethylammonium bromide (CTAB) capping surfactant was used, and AgNO3 was added to the last growth solution to promote the formation of the five side branches. Through an investigation of the products collected by ad…
