The synthesis of a promising brain imaging agent 4-[F-18]fluoro-4-deoxy-N-acetyl-1,3,6-tri-O-acetylglucosamine, 2, was successfully accomplished from commercially available N-acetyl glucosamine in 5 steps. The non-decay corrected radiochemical yield and purity were found to be 31% ± 4% (n = 3) and >98% respectively. The total reaction time for radio labelling step was 50 min.

A moisturizing cream containing 25 wt% of an organic solvent, diethylene glycol monoethyl ether (DEGEE), is observed to be stabilized by an emulsifying wax blend of cetearyl alcohol, dicetyl phosphate, and ceteth-10 phosphate (tradename Crodafos CES). Polarized light microscopy indicates that the Crodafos CES helps to produce a liquid-crystal stabilized oil-in-water emulsion, which is physically stable for months under accelerated aging conditions and chemically stable over the full topical pH range of 3.5 to 9. Emulsion globule size in the cream is observed to be dependent on the degree of emulsifying wax neutralization, with the globule size decreasing with increasing cream pH. The superior solubilizing properties of DEGEE combined with the full pH range and liquid-crystal stabilizing properties of the Crodafos CES give this formulation the potential for a wide range of applications in the topical delivery of active pharmaceutical ingredients.

这是一位即将退役的海军写给新婚妻子的书信。读罢,不禁想起了林觉民的《与妻书》,“窗外疏梅筛月影,依稀掩映,吾与汝并肩携手,低低切切,何事不语,何情不诉!……”两封“与妻书”,一中一外,一古一今,同中有异。新婚燕尔,分隔两地,借信笺传情,字里行间无不流露出浓情蜜意,这是两者的共同点。但由于所处时代以及环境等种种不同,两者又各有特色:海军的“与妻书”通过一系列的排比句细说深情和思念,将爱情的甜蜜和生活的幸福烘托得恰到好处;而林觉民的《与妻书》,确切说是“与妻诀别书”,却是一字一血泪,一语一悲恸!有心的读者不妨把两者对比来读,相信会有所感悟。
