Evaluation of genotoxic effects of sodium propionate, calcium propionate and potassium propionate on the root meristem cells of Allium cepa
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The effects of different treatments with food preservatives, sodium propionate (SP), calcium propionate (CP) and potassium propionate (PP), on the cytology and DNA content of Allium cepa were investigated. Five concentrations ...
A rare variation of the right middle suprarenal artery
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2007)
According to general knowledge, the suprarenal. gland is supplied by three sources: the phrenic artery, the abdominal. aorta and the renal artery. Since the gland tacks a hilus, and particularly because of its clinical ...
Comparison of body composition analysis methods in clinical routine
(KARGER, 2000)
Background: Skinfold thickness (SFT) and bioelectrical impedance (BIA) are readily available and commonly used techniques in patient monitoring for body composition analysis (BCA) in clinical practise. Another one, dual-energy ...
Prognostic value of the expression of Ki-67, CD44 and vascular endothelial growth factor, and microvessel invasion, in renal cell carcinoma
(BLACKWELL PUBLISHING LTD, 2004)
To determine if use of cell proliferation, cell adhesion, level of angiogenesis-related factors and presence of microscopic vascular invasion (MVI) could better predict the biological behaviour of renal cell carcinoma ...
Swelling equilibria and dye adsorption studies of chemically crosslinked superabsorbent acrylamide/maleic acid hydrogels
(PERGAMON-ELSEVIER SCIENCE LTD, 2002)
Superswelling acrylamide (AAm)/maleic acid (MA) hydrogels were prepared by free radical polymerization in aqueous solution of AAm with MA as comonomer with some multifunctional crosslinkers such as trimethylolpropane ...
Intersubband optical absorption of double Si delta-doped GaAs layers
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004)
For different applied electric fields the intersubband transitions of double Si delta-doped GaAs structures are theoretically investigated for a uniform donor distribution. The electronic structure has been calculated by ...

(MARCEL DEKKER INC, 2003)
Heavy metal contents of street dust samples collected from seven sites located in and around urban areas in Sivas city, Turkey, were determined by atomic absorption spectrometry after digestion using a mixture of acids. ...
Determination of trace elements in fly ash samples by FAAS after applying different digestion procedure
(ELSEVIER SCIENCE BV, 2005)
The fly ash samples obtained from Kangal Power Plant were prepared for FAAS analysis by a new approach. The trace elements of the fly ash samples were leached with appropriate solvents under suitable conditions. The leaching ...
Syn, anti, and finally both conformations of cyclic AMP are involved in the CRP-dependent transcription initiation mechanism in E. coli lac operon
(JOHN WILEY & SONS LTD, 2008)
The cyclic AMP receptor protein (CRP) of Escherichia coli regulates the activity of more than 150 genes. Allosteric changes in CRP structure accompanied by cAMP binding, initiate transcription through protein binding to ...
