Intraoperative anaphylactic shock in a child with no history of type I hypersensitivity
(Tehran Univ Medical Sciences, Tehran, 2008)
Natural rubber latex is the second most implicated agent in intraoperative anaphylactic reactions. This report describes a case of intraoperative anaphylaxis occurring in a non-atopic fourteen-year-old girl undergoing ...
Screening of selenium absorption ability of mycelia of selected Pleurotus species
(Teknoscienze Publ, Milan, 2006)
Pleurotus species are economically high praised due to their edible and medicinal properties. Selenium is a trace element with antioxidant and anticarcinogenic effects. The aim of our research was to investigate the influence ...
Generation and intermolecular additions of pyridylmethyl radicals
(Georg Thieme Verlag Kg, Stuttgart, 2008)
2-, 3-, or 4-Pyridylmethyl radicals can be made to add to nonactivated alkenes to give a variety of otherwise inaccessible pyridine derivatives. Bicyclic structures can be obtained by combining the radical addition with ...
Synthesis, characterization and antitumor activity of novel N-substituted alpha-amino acids containing ferrocenyl pyrazole-moiety
(Elsevier Science Sa, Lausanne, 2009)
A series of new N-[(3-ferrocenyl-1-phenylpyrazol-4-yl)methyl] alpha-amino acids were prepared and characterized by a range of spectroscopic techniques and cyclic voltammetry. The in vitro antitumor activity of all synthesized ...
Yeast surface display for the expression, purification and characterization of wild-type and B11 mutant glucose oxidases

Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the ...
Electrochemical determination of sertraline in pharmaceutical formulation and serum using a gold electrode in a pH 8.4 bicarbonate solution
(Springer International Publishing, 2021)
The electrochemical characterization of sertraline at gold electrode was examined by cyclic voltammetry measurements (CV) in pH 8.4 bicarbonate buffer. Then Au electrode was evaluated for the quantitative determination of ...
A new depsidone of Lobaria pulmonaria with acetylcholinesterase inhibition activity
(Informa Healthcare, London, 2013)
The phytochemical investigation conducted on a foliose lichen, Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), led to the isolation of a new depsidone in the form of its diacetate derivative which showed a moderate ...
Possible Sources of Heavy Metals in Urban Soils: Example from Belgrade, Serbia
(Scibulcom Ltd, Sofia, 2010)
The content of heavy metals over time has been continuously increasing in urban soils as a consequence of industrialisation and often unclear sets of environmental controls and protection procedures. However, the role of ...
An easily accessed class of recyclable hypervalent iodide reagents for functional group oxidations: bis(trifluoroacetate) adducts of fluorous alkyl iodides, CF3(CF2)(n-1)I(OCOCF3)(2)
(Royal Soc Chemistry, Cambridge, 2005)
Reactions of commercial fluorous alkyl iodides RfnI (1-R-fn; R-fn = CF3(CF2)(n-1); n = 7, 8, 10, 12) with 80% H2O2 and trifluoroacetic anhydride give RfnI(OCOCF3)(2) (2-R-fn; 89-97%). These rapidly oxidize 1,4-hydroquinones ...
Gibberellic acid nitrite stimulates germination of two species of light-requiring seeds via the nitric oxide pathway
(New York Acad Sciences, New York, 2005)
We used two species of light-requiring seeds, Paulownia tomentosa, which have absolute light requirement (no germination in darkness), and Stellaria media seeds, which germinate in darkness to a certain extent because of ...
