El humo del tabaco contiene otros alcaloides que pueden contribuir a la adiccion, como la cotinina (COT). En este estudio se evaluaron los posibles efectos de la COT en ratas durante el sindrome de abstinencia nicotinica midiendo la actividad locomotora espontanea (ALE) utilizando el test del campo abierto. El estudio se llevo a cabo con dos grupos de ratas que recibieron NI 10 mg / kg / dia en agua potable durante 120 dias (grupos A y B). Luego, en el grupo A, se sustituyo NI por agua potable y en el grupo B, sustituido por COT 12 mg / kg, durante 24 horas en ambos grupos. La actividad locomotora espontanea se registro al final del dia 120 (nivel basal) y al final del dia 121, al final del periodo de abstinencia. Los resultados obtenidos se compararon con las medi...

It is centered around the study of Clifford algebra valued null solutions, called discrete monogenic functions, of a discrete Dirac operator, i.e. a first order, Clifford vector valued difference operator. In this contribution, we establish a Cauchy-Kovalevskaya extension theorem for discrete monogenic functions defined on the grid Z m h of m-tuples of integer multiples of a variable mesh width h. Convergence to the continuous case is investigated. As illustrative examples we explicitly construct the Cauchy-Kovalevskaya extensions of the discrete delta function and of a discretized exponential.

However, it seems much less clear what exactly political movements and uprising such as the Arab Spring, the European protests against austerity policies, and the US-Occupy movement have in common. This article takes the massive presence of movements in public spaces as a point of departure, and analyzes the global cycle of protests through an urban lense. Arguing that the process of neo-liberalization, the austerity measures aiming at the management of the current crisis, and people’s responses on the streets’ are strongly articulated through urban space, the article discusses similarities and differences between movements in various regional contexts.

In general, these samples showed quantities that varied between a few hundredths of a ppmm to slightly more than 1 ppmm, although in some cases and for certain pesticides, depending on the locations, the levels found were definitely higher. With the exception of Dieldrin, which appeared in only one sample/in what would seem to be its course few hundredths of a ppm, to slightly more than 1 ppmm, although in some cases and for certain pesticides found were the same as those reported in previous investigations. The isolated cases of high pesticide contents in water samples drawn at wharves and of snow in the vicinity of Almirante Brown Base show up clearly the influence of human activity on the contamination of the environment.

The results obtained in the actual study show a clear correlation between occurrence of Alzheimer’s disease and the

HEALTHY ADULTS PEOPLE OCCUPATIONALLY EXPOSED Blood lead levels were determined for an adult healthy population not occupationally exposed to lead, living in the City of Buenos Aires and Greater Buenos Aires. Venous blood samples from subjects of both genders (n = 278) were processed by means of electrothermal atomizationatomic absorption, at 283.3 nm. Lead blood values obtained for the total population ranged between 2.27 and 17.35 µg/dL. The female population studied (n =123) showed values between 1.99 and 15.8 µg/dL, which were not statistically different from those obtained for the male population (n =119), and which ranged between 3.06 and 17.67 µg/dL. The natural logarithms of all values were adjusted to the Gaussian distribution.
