Histopathologic and immunohistochemical analyses of Hodgkin' s disease and the correlation with Epstein-Barr virus
(1999)
The aim of this study is to evaluate the frequency of histologic subtypes of Hodgkin's disease (HD) as well as their relationship with age, gender and localization, immunohistochemical (IHC) features of Reed Sternberg (RS) ...
Adsorption mechanisms of phenol and methylphenols on organoclays
(MULTI SCIENCE PUBL CO LTD, 1999)
Eight clay-organic complexes were synthesized by placing quaternary ammonium cations (QUATs) on to bentonite (B) and kaolinite (K) by cation exchange. The organic cations used were hexadecyltrimethylammonium (HDTMA), ...
Transfection of human kidney epithelial 293 cells with bacterial cytosine-5-methyltransferase M. Msp 1and the SV40 nuclear localisation sequence of VP1
(1999)
The aim of this study was to con-struct a plasmid that would direct the expres-sion of a bacterial DNA methyltransferase in cultured mammalian cells. It was carried out with a PCR-based strategy for introducing three ...
Improvement in electroabsorption and the effect of the electric field in the tuneable wavelength converter
(1999)
The numerical results of the study of a novel wavelength converter which can be tuned with the application of an external field are presented. For this device, exciton binding energies, radiuses and the absorption coefficient ...
Evaluation of venous ulcers
(1999)
Alt ekstremitenin venöz staz ülserleri yaygın olarak görülür ve nüfusun %1'ini potansiyel olarak etkiler. Kronik venöz yetmezliği olan hastaların yaklaşık olarak üçte birinde on yılı aşkın bir sürede alt ekstremite ülserleri ...
Development of the fluorescent microsphere technique for quantifying regional blood flow in small mammals
(WILEY, 1999)
We have demonstrated that the fluorescent microsphere technique can be used in small mammals for accurate determination of regional blood flows. Hn particular we have shown that 100% recovery of trapped microspheres is ...
Sorption of methylene blue from water by organoclays
(1999)
Isotherms were measured for sorption of methylene blue by organoclays. The organoclays were prepared from kaolinite and bentonite by replacing the natural exchangable cations of the quaternary ammonium ions HDTMA ...
Grooming behaviours in the Hymenoptera (Insecta): potential phylogenetic significance
(WILEY-BLACKWELL, 1999)
Grooming behaviours from representatives of 36 families of Hymenoptera were video recorded and analysed. Thirty-three distinct types of grooming movements were recognized. The evolutionary pattern of each behaviour is ...
Ab initio study of the protometric tautomerism of adenine
(1999)
Eight tautomers of adenine have been studied by using ab initio theory in the gas phase and in solution. Their stability order has been determined by using the HF/3-21G approximation. The HF/3-21G level calculations predict ...
The effect of lead inhalation on rat lung morphology
(1999)
Lead may exert toxic effects on several organ systems, but those in the lung are the most insidious. Therefore the aim of the present study was to investigate the morphological alterations caused by lead intoxication in ...
