13. Lanthanide dithiocarbamate complexes: efficient catalysts for the cyanosilylation of aldehydes
Uma nova classe de complexos ditiocarbamato de lantanídeo foi usada para promover a cianosililação de aldeídos com elevados rendimentos à temperatura ambiente. Esta é a primeira aplicação de ditiocarbamato de lantanídeo atuando como ácido de Lewis.

14. Increased expression of p38 mitogen- activated protein kinase is related to the acute renal lesions induced by gentamicin
Mitogen-activated protein kinases (MAPK) may be involved in the pathogenesis of acute renal failure. This study investigated the expression of p-p38 MAPK and nuclear factor kappa B (NF-kappaB) in the renal cortex of rats treated with gentamicin. Twenty rats were injected with gentamicin, 40 mg/kg, im, twice a day for 9 days, 20 with gentamicin + pyrrolidine

15. Antioxidant potential and physical-chemical characteristics of organic tomato (Lycopersicon esculentum) in comparison with conventional tomato / Avaliação do potencial antioxidante e de algumas características físico-químicas do tomate (Lycopersicon esculentum) orgânico em comparação ao convencional
Objective: The main objective of this survey was to compare the cultivation effect (organic and conventional) over the physical-chemical characteristics, the content of antioxidant compounds and the antioxidant activity of tomatoes Carmen cultivar. Considering that home preparation of the food may be a significant effect over the level of nutrients in relati

16. DEVELOPMENT OF METHODOLOGIES FOR THE ARSENIC SPECIATION IN WATERS AND SALINE MATRICES BY ADSORPTIVE CATHODIC STRTIPPING VOLTAMMETRY / DESENVOLVIMENTO DE METODOLOGIAS PARA A ESPECIAÇÃO DE ARSÊNIO EM ÁGUAS E MATRIZE SALINAS EMPREGANDO VOLTAMETRIA ADSORTIVA DE REDISSOLUÇÃO CATÓDICA
The present work reports the development of methodologies for the arsenic speciation in waters and saline matrices by adsorptive cathodic stripping voltammetry (AdCSV). The determination of As(III) by AdCSV was investigated and optimized using the organic ligand sodium diethyldithiocarbamate (DDC) in acidic medium. The main experimental parameters that have

17. Synthesis and characterization of oxovanadium (IV) dithiocarbamates with pyridine
We report the synthesis and study of a new series of oxovanadium (IV) dithiocarbamate adducts and derivatives with pyridine and cyclohexyl, di-iso-butyl, di-n-propyl, anilin, morpholin, piperidin and di-iso-propyl amines. The complexes have been characterized by analytical, magnetochemical, IR, visible-UV spectral and thermal studies, and are assigned the fo

18. Inhibition of cis-platinum nephrotoxicity by diethyldithiocarbamate rescue in a rat model.
The nephrotoxic effects of cis-dichlorodiammineplatinum(II) (NSC-119875) administered to male F344 rats at the median lethal dose (LD50; 7.5 mg/kg) were inhibited by treatment with sodium diethyldithiocarbamate (500 or 750 mg/kg) between 1 and 4 hr after cis-platinum administration. Those animals receiving cis-platinum alone had mean serum blood urea nitroge

19. In vitro evaluation of BO-3482, a novel dithiocarbamate carbapenem with activity against methicillin-resistant staphylococci.
BO-3482, a dithiocarbamate carbapenem, inhibited clinical isolates of methicillin-resistant staphylococci (MRS) at 6.25 microg/ml (MIC at which 90% of isolates tested are inhibited [MIC90]), while the MIC90 of imipenem was > 100 microg/ml. BO-3482 was generally less active than imipenem against methicillin-susceptible Staphylococcus aureus, streptococci, ent

20. Antiviral Effects of Pyrrolidine Dithiocarbamate on Human Rhinoviruses
Human rhinoviruses (HRVs) are the predominant cause of the common cold. The frequency of HRV infections in industrial countries and the lack of effective therapeutical treatment underline the importance of research for new antiviral substances. As viral infections are often accompanied by the generation of oxidative stress inside the infected cells, several

21. Therapeutic efficacy of BO-3482, a novel dithiocarbamate carbapenem, in mice infected with methicillin-resistant Staphylococcus aureus.
The in vivo activity of BO-3482, which has a dithiocarbamate chain at the C-2 position of 1beta-methyl-carbapenem, was compared with those of vancomycin and imipenem in murine models of septicemia and thigh infection with methicillin-resistant Staphylococcus aureus (MRSA). Because BO-3482 was more susceptible than imipenem to renal dehydropeptidase I in a ki

22. Regulation of p53 by metal ions and by antioxidants: dithiocarbamate down-regulates p53 DNA-binding activity by increasing the intracellular level of copper.
Mutations in the p53 tumor suppressor gene frequently fall within the specific DNA-binding domain and prevent the molecule from transactivating normal targets. DNA-binding activity is regulated in vitro by metal ions and by redox conditions, but whether these factors also regulate p53 in vivo is unclear. To address this question, we have analyzed the effect

23. Laboratory studies of disinfectants against Legionella pneumophila.
Legionella pneumophila suspended in tap water was exposed to biocides recommended for inhibiting biological growth in cooling towers and evaporative condensers of air-conditioning systems. Chlorine, 2,2-dibromo-3-nitrilopropionamide, and a compound containing didecyldimethylammonium chloride and isopropanol were effective in destroying concentratiois of 10(5

24. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid
Cernik, A. A. (1970).Brit. J. industr. Med.,27, 40-42. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid. A method is described for the determination of lead in whole blood containing ethylene-diaminetetra-acetic acid. Proteins were precipitated by 2·0 m perchloric acid. The ion
