A search for volatile nitrosamines in East African spirit.

A search for nitrosamines in East African spirit samples from areas of varying oesophageal cancer frequency.

Following the report of the presence of nitrosamine-like substances in samples of homemade spirit from Zambia, which had been obtained from an area where cancer of the oesophagus is common, samples of distilled alcoholic drinks were collected throughout western Kenya and southern Uganda from areas where the frequency of cancer of the oesophagus varies from very common to very rare. The 44 sampl...

A comparative analysis of IT outsourcing readiness in the East African community

Developing countries are increasingly relying on Information and Communication Technology (ICTs) for their socio-economic development. Many countries have achieved faster gross domestic product (GDP) growth through information technology (IT) outsourcing, which is now largely recognized as a strategic management practice that can provide a competitive advantage in business. The East African Com...

Volatile N-nitrosamines in the urine of normal donors and of bladder cancer patients.

Volatile N-nitrosamines were detected in the urine of male volunteers with gas-liquid and high-pressure liquid chromatography interfaced to the thermal energy analyzer. Of 50 samples from normal males, 10 contained nitrosodimethylamine (0.02 to 0.10 micrograms/liter), 6 contained nitrosodiethylamine (0.02 to 3.10), 9 contained nitrosomorpholine (0.006 to 0.67), and none contained nitrosodibutyl...

Quantitation of urinary volatile nitrosamines from exposure to tobacco smoke.

A sensitive and selective method was developed and validated to detect six volatile nitrosamines (N-nitrosodimethylamine, N-nitrosomethylethylamine, N-nitrosodiethylamine, N-nitrosopiperidine, N-nitrosopyrrolidine and N-nitrosomorpholine) in human urine. This method uses a liquid-liquid extraction cartridge followed by analysis with gas chromatography-tandem mass spectrometry (GC-MS-MS) and qua...
