Los ensayos de MTT y WST-1 para determinar la viabilidad celular se utilizan con frecuencia, sin considerar una opción diferente; sin embargo, ambos métodos requieren procedimientos y materiales específicos que no son comunes entre ellos y por lo tanto im... see more

Streams Mandacaru, Maringá, Miosótis and Nazareth in the urban area of Maringá, Estado do Paraná, Brazil are affected by the local population’s polluting practices. Meristemic cells of Allium cepa L. roots were used as test system to evaluate the cytotoxi... see more

A series of novel optically pure oxime pseudoesters derivatives were syn­thesized by the reaction of substitute keto oximes with various N-sub­sti­tuted a-amino acids chlorides in the presence of triethylamine and dichloro­methane at 0 °C, and their struc... see more

The immunological and biochemical changes caused by pregnancy may uncover new aspects of immune tolerance, applicable in physiological and pathological contexts, and show up new therapeutic strategies for improving pregnancy outcomes. Isoimmune conflict i... see more

Three piperidone curcumin analogues (N-methyl-(3E,5E)-3,5-bis-(2-chlorobenzylidene)-4-piperidone (1), N-methyl-(3E,5E)-3,5-bis-(3-bromobenzylidene)-4-piperidone (2) and N-methyl-(3E,5E)-3,5-bis-(4-chlorobenzylidene)-4-piperidone (3)) were synthesized from... see more

Synthesis of novel quinazoline derivatives was performed from reaction of N-benzoyl substituted piperazine-1carbothioamide with 4-(2-chlormethyl) quinazoline-4-yloxy phenyl benzamide derivatives and screened for their in vitro cytotoxic activity by MTT as... see more
