The synthesis and resolution of a class of chiral organic fluorophores, axially chiral 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (Ax*-BODIPY), is described. Ax*-BODIPYs were prepared through a modular synthesis combined with a late stage Heck functionalisation. Resolution was achieved by preparative chiral HPLC. Absolute stereochemical assignment was performed by comparison of experimental EC...

the present experiment was conducted to evaluate the effects of different levels of vitaminpremix(vp), fed during the last three weeks of a broiler rearing period (22-42 days), on its growthperformance and carcass characteristics. four hundred 22 day old broilers received diets containingfour levels of supplementary vp (0, 33.33, 66.66 and 100%) each at a different weeks of finisherperiod. the ...

we are reporting a case of 47 chromosome complement with an extra rearranged chromosome 22pter→22qll:: llq23 → llqter in a child with multiple malformations whose mother has a balanced reciprocal translocation t(1l,22) with a history of two previous abortions. we emphasize the importance of family study in such cases.
