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 ...
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 ...
Flow analysis in centrifugal compressor vaneless diffusers
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2008)
Flow computations have been performed in vaneless diffuser (diam, 1 m), in low speed backswept centrifugal compressor using finite volume method (FVM),coupled with Standard k-epsilon turbulent model by solving oil commercial ...
Rare earth double sulfates from pre-concentrated bastnasite
(ELSEVIER SCIENCE BV, 2008)
A mixture of rare earth double sulfates was produced from a Turkish bastnasite-containing pre-concentrate (low grade concentrate) by sulfuric acid baking, subsequent water leaching and precipitation with sodium sulfate. ...
Stimulation of epithelial cell matrix metalloproteinase (MMP-2,-9,-13) and interleukin-8 secretion by fusobacteria
(WILEY-BLACKWELL, 2008)
Background/aim: Bacterial pathogens involved in periodontal diseases exert their destructive effects primarily by stimulating the host cells to increase their secretion of proinflammatory cytokines and matrix metalloproteinases ...
Role of mean platelet volume in triagging acute coronary syndromes
(SPRINGER, 2008)
Background: Acute coronary syndromes, characterized by the rupture of unstable plaque and the subsequent thrombotic process involving platelets, have been increasing in relative frequency. The central role of platelet ...
Crustal structure of the eastern part of Central Anatolia (Turkey)
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)
This study aims to examine crustal structure in the eastern part of central Anatolia using the magnetotelluric (MT) method. MT data have been collected from 37 stations along a north-south 220 km profile crossing in ...
Measurements of Reynolds stresses in centrifugal compressor vaned diffusers
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008)
A phase lock loop sampling technique has been developed in order to perform detailed measurements for the flow field downstream of a turbomachinery rotor. Measurements have been carried out in the vaned diffuser of a ...
The effects of magnetic field on the biomechanics parameters of soleus and extensor digitorum longus muscles in rats with streptozotocin-induced diabetes
(MARY ANN LIEBERT INC, 2008)
Background: The aim of this study was to determine the effects of the magnetic field (MF) on the isometric contractile characteristics of the soleus and extensor digitorum longus (EDL) muscles in rats both with and without ...
