Jimenez O and Gonzalez ADV.

Journal of the American Oil Chemists' Society, 73 (12), 1685-1689 (1996)

Solitary plasmacytoma of bone vs. extramedullary plasmacytoma and their relationship to multiple myeloma.

J Corwin et al.

Cancer, 43(3), 1007-1013 (1979-03-01)

Solitary plasmacytoma of bone (SPB) and extramedullary plasmacytoma (EMPC) are unusual solitary tumors of plasma cell origin. The clinical differences between these tumors and multiple myeloma are the subject of continued study. This review examines the radiotherapy experience at M.

The effects of lead-resistant pseudomonads on the growth of Triticum Aestivum seedlings under lead stress.

S Hasnain et al.

Environmental pollution (Barking, Essex : 1987), 81(2), 179-184 (1993-01-01)

Five Pseudomonad strains, SPb-1, SPb-2, SPb-3, (from a water sample), SPb-4, and SPb-5 (from rhizosphere), which could tolerate lead acetate up to 1000 microm ml(-1), were isolated from an industrially polluted area around Kasoor, Pakistan. Only SPb-5 harbours a lead-resistant

Determination of diethanolamine and N-nitrosodiethanolamine in fatty acid diethanolamides.

H J Chou

Journal of AOAC International, 81(5), 943-947 (1998-10-17)

Diethanolamine (DEA) is a precursor of N-nitrosodiethanolamine (NDELA), an animal carcinogen. A gas chromatographic (GC) method was developed for determining DEA in fatty acid diethanolamides that are commonly used in cosmetic products. Methanolic solutions of the amides were analyzed by

Determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography.

P M Scott et al.

Journal - Association of Official Analytical Chemists, 69(5), 889-893 (1986-09-01)

Nivalenol (NIV) is an important Fusarium mycotoxin shown to occur naturally in grains from several countries. Extraction and cleanup procedures previously described for trichothecene analysis have been modified to give good recoveries of NIV from cereal products. The extraction solvent

Speciation of nitrogen compounds in gasoline and diesel range process streams by capillary column gas chromatography with chemiluminescence detection.

Birbal C

Journal of Chromatographic Science, 35 (3), 97-104 (1997)

Development of a passive sampler to measure personal exposure to gaseous PAHs in community settings.

Zhihua Fan et al.

Environmental science & technology, 40(19), 6051-6057 (2006-10-21)

A sensitive, simple, and cost-effective passive sampling methodology was developed to quantify personal exposure to gaseous polycyclic aromatic hydrocarbons (PAHs). A Fan-Lioy passive PAH sampler (FL-PPS) is constructed from 320 sections of 1-cm long SPB-5 GC columns (0.75-mm i.d. and

Solid-phase extraction-thin-layer chromatography-gas chromatography method for the detection of hazelnut oil in olive oils by determination of esterified sterols.

Luisito Cercaci et al.

Journal of chromatography. A, 985(1-2), 211-220 (2003-02-13)

The sterol composition of extra virgin olive oil is very characteristic and, thus, has become a helpful tool to detect adulterations with other vegetable oils. Special attention has been addressed to the separate determination of the free and esterified sterol

Determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography.

Scott PM

Journal - Association of Official Analytical Chemists, 69 (5), 889-893 (1985)

[Use of polychlorinated biphenyl congener analysis for monitoring food and raw material of animal origin].

V Gajdůsková et al.

Veterinarni medicina, 37(8), 471-478 (1992-08-01)

Occurrence of individual polychlorinated biphenyl (PCB) congeners in the environment, foodstuffs and other biological materials was assessed. Analysis of specific PCB congeners (28, 52, 101, 138, 153, 180), occurring in animal raw materials and foodstuffs most frequently, has been implemented.

Trace determination of 1-octacosanol in rat plasma by solid-phase extraction with Tenax GC and capillary gas chromatography.

D Marrero Delange et al.

Journal of chromatography. B, Biomedical sciences and applications, 762(1), 43-49 (2001-10-09)

1-Octacosanol is the major component of policosanol, a new natural lowering-cholesterol agent. A sensitive solid-phase extraction with a Tenax GC capillary gas chromatography method for determining the proportion of this fatty alcohol in plasma after its denaturation with trichloroacetic acid

Positive- and negative-ion mass spectrometry and rapid clean-up of some carbamate pesticides.

O Suzuki et al.

Forensic science international, 46(3), 169-180 (1990-07-01)

Positive-ion electron impact (PIEI), positive-ion chemical ionization (PICI) and negative-ion chemical ionization (NICI) mass spectra of 9 carbamate pesticides are presented. In the PIEI mode, the spectra showed small molecular peaks, intense or base peaks due to M - CH3NHCO

Characterization and quantification of 4-methylsterols and 4,4-dimethylsterols from Iberian pig subcutaneous fat by gas chromatography-mass spectrometry and gas chromatography-flame ionization detector and their use to authenticate the fattening systems.

J M Jurado et al.

Talanta, 106, 14-19 (2013-04-20)

4-Methylsterols and 4,4-dimethylsterols of 47 samples of subcutaneous fat from Iberian pigs reared on two different fattening systems, "Extensive" and "Intensive", have been analyzed by GC-MS and GC-FID. The lipids were extracted by melting the subcutaneous fat in a microwave

Estimation of serum nicotine by gas chromatography in smokers, passive smokers and never smokers.

Zil-a-Rubab et al.

JPMA. The Journal of the Pakistan Medical Association, 62(8), 790-793 (2013-07-19)

To compare the serum nicotine levels in smokers, passive smokers and those with no exposure to cigarette smoke. The comparative study spanning two years was conducted in Ziauddin Medical University, Karachi, in collaboration with HEJ Research Institute of Chemical Sciences
