Phosphorus–nitrogen compounds. Part VI. Aminolysis of octachlorocyclotetraphosphazatetraene and the crystal structure of 2-trans-6-bis(n-propylamino)-2,4,4,6,8,8-hexakis-tert-butylaminocyclo-2λ5, 4λ5, 6λ5, 8λ5-tetraphosphazatetraene
(Elsevier Science Bv, 2003)
The reactions of 2-trans-6-N4P4(NBPrn)(2)CI6 (2), which was obtained from N4P4Cl8 (1) and n-propylamine, with pyrrolidine and t-butylamine in different solvents have been studied. Compound (2) gave two different products, ...
Fas-mediated pathway and apoptosis in normal, hyperplastic, and neoplastic endometrium
(Academic Press Inc Elsevier Science, 2003)
Introduction. Abnormalities in the control of cell proliferation and apoptosis have been suggested to contribute to the development and progression of neoplasia. There are at least two pathways that activate apoptosis. The ...
Perioperative intravenous adenosine infusion to extend postoperative analgesia in brachial plexus block
(Lippincott Williams & Wilkins, 2003)
Background and objective: Adenosine infusions have been shown to reduce requirements of anaesthetics, to decrease the need for postoperative analgesics and to attenuate hyperaesthesia related to neuropathic pain. We decided ...
Comparative biosorption of mercuric ions from aquatic systems by immobilized live and heat-inactivated Trametes versicolor and Pleurotus sajur-caju
(Elsevier Sci Ltd, 2003)
Trametes versicolor and Pleurotus sajur-caju mycelia immobilized in Ca-alginate beads were used for the removal of mercuric ions from aqueous solutions. The sorption of Hg(II) ions by alginate beads and both immobilized ...
Disclosure of unnoticed rib fractures with the use of ultrasonography in minor blunt chest trauma
(Elsevier Science Bv, 2003)
Objective: Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of chest X-rays in showing the rib fractures is limited particularly in those involving the cartilage part of the ...

Effect of botulinum-A toxin to cremaster muscle: an experimental study
(Springer-Verlag, 2003)
Objective: A controversy exists on the definition, etiology and treatment of the retractile testes. In the present experimental study, we aimed to show the effect of botulinum-A toxin (Botox) on cremasteric muscle of a ...
Dye-ligand immobilized IPNs membrane for removal heavy metal ions
(Wiley-V C H Verlag Gmbh, 2003)
We have developed a novel approach to obtain high metal sorption capacity utilizing a membrane containing chitosan and an immobilized reactive dye (i.e. Reactive Yellow-2). The composite membrane was characterized by SEM, ...
Diagnostic implications of telomerase activity in pleural effusions
(European Respiratory Soc Journals Ltd, 2003)
The aim of the present study was to investigate the diagnostic efficacy of telomerase activity for discrimination of malignant and benign pleural effusions. Pleural effusions were collected from 109 consecutive patients ...
