In this study we explore the patent ownership for the innovations created by Canadian nanotechnology inventors. We find that
although there is a great innovative potential and inventive productivity among Canadian researchers, a lot of the intellectual
property actually leaves the country: Around 50% of the nanotechnology patents invented by Canadian inventors are owned by
foreign assignees. We also note the predominance of private companies among the patent owners. Almost one-third of all the
Canadian-invented nanotechnology patents is assigned to a single American firm, Xerox Corporation. Furthermore, we explore
the role of Canadian nanotechnology star inventors. The results show that the fruits of their great inventive productivity
are collected outside Canada. 相似文献

We reported on the death by poisoning of a one-month-old baby that had followed the death of one of her sister (due to cyamemazine overdose). Exhumation of the corpse was done 8 months after burial and revealed the presence of amitriptyline. Parent drug and its metabolite were analysed by HPLC-MS/MS in positive ionisation mode on a C(18) analytical column using a gradient of acetonitrile and 2mM formate buffer at pH=3. Quantification is based on the main ion m/z=233, the common product ion of nortriptyline (MH(+), m/z 264), amitriptyline (MH(+), m/z 278) and nortriptyline D3 used as internal standard (MH(+), m/z 267). Amitriptyline and nortriptyline in the liver were measured at a concentration of 29.8 and 3.6 μg/g, respectively. Hair analyses revealed the presence of amitriptyline and nortriptyline at concentrations of 1811 and 43 pg/mg, respectively, while complementary analyses showed the presence of bromazepam in the hair at a concentration of 740 pg/mg, thus documenting previous administrations. The mother confessed later having used the drinkable form of the pharmaceutical LAROXYL(?) by pouring the content of a 20 ml bottle (at 40 mg/ml) into the feeding-bottle of her child. The milk was sweet but still bitter and following the testimony of a close relative, the whole family helped to feed the crying baby. 相似文献
