The Roman high(RHA) and low-Avoidance (RLA) rats were selectively bred for rapid vs poor acquisition of two-way active avoidance behavior. These lines differ in numerous behavioral traits, with RLA rats being more fearful/anxious than RHA rats, and the latter being novelty-seekers and showing larger intake of, and preference for, addictive substances including ethanol (ETH). Moreover, several differences in central dopaminergic, serotonergic, and GABAergic functions have been reported in these two lines. Since those neural systems are involved in the regulation of ETH consumption, it was considered of interest to investigate: 1) the differences in ETH intake and preference between RHA and RLA rats, 2) the effects of ETH on DA release in the shell of the nucleus accumbens (AcbSh) using brain microdialysis. ETH solutions of increasing concentrations (2% - 10%) were presented on alternate days in a free choice with water. To examine ETH intake and preference stability, animals were subsequently switched to daily presentations of 10% ETH for 10 consecutive days. RHA rats consumed significantly larger amounts of ETH and displayed higher ETH preference than did RLA rats throughout the acquisition and maintenance phases. Following chronic exposure to ETH the animals were habituated to a restricted access to ETH schedule (2% ETH, 2 h per day × 4 days) before surgical implantation of a dialysis probe in the AcbSh. Under these experimental conditions, voluntary ETH intake (2%, 1 h, p.o.) produced a significant increase in accumbal DA output in RHA rats but not in their RLA counterparts. Finally, the i.p. administration of ETH (0.25 g/kg) to na?ve Roman rats produced a significant increment in accumbal DA output only in RHA rats. These results indicate that the mesolimbic dopaminergic system of RHA rats is

Abstract: crystals are of an increasing importance in our society. in the beginning of the xxi century, crystal engineering started to develop, emerging from the main area of crystallography. in spite of the dominating bio- and bio-logical trends in modern technology, we cannot ignore our life on earth (and other planets?) surrounded by natural crystals, in the composition of rocks, minerals, metals, and as the basic units of solids, a lot of them being inorganic. therefore we must understand them, improving our knowledge on them. we can?t afford to neglect the classical sciences like inorganic and analytical chemistry related to their studies: they seem as if they became out of fashion (at least in our country!), but we cannot deny their importance for understanding mineralogy, geology, materials sciences, environmental studies, bioinorganic sciences (the role of metals in our bodies as active centres of enzymes?) etc.. if we neglect and dismember chemistry, the future generations will very fast loose the skills to understand our surroundings and furthermore, their own bodies! on the rocks is a research project for inorganic chemical education, consisting on crystal growth on rough surfaces, (rocks, minerals, shells, metallic wires, etc.)[1-10].these substrates, acting as "hosts", are introduced in supersaturated solutions of chemicals, promoting a faster nucleation and strongly stimulating crystal growth. only substances that can afford large single crystals easily are chosen. mainly ionic salts fairly soluble in water have been studied, a few of them here described. the technique requires inexpensive glassware and is feasible in schools poorly equipped, under close surveillance and strict safety rules. the large single crystals embedded on the host rocks look like "minerals" (synthetic!), and their beauty is a powerful tool to attract students for chemistry and other sciences sharing a common interest on crystals. many concepts can be introduced during and after the prepar

Abstract: O crescimento de cristais "On the Rocks" utiliza suportes rugosos para estimular a nuclea o, a protec o dos núcleos cristalinos e o seu acesso aos nutrientes, levando à forma o de grandes cristais [1-10]. Rochas, minerais e conchas s o mergulhados em solu es sobressaturadas de substancias solúveis em água, seleccionadas entre aquelas que cristalizam com relativa facilidade. A beleza dos cristais produzidos, quer na forma de grandes monocristais, maclas, agregados ou whiskers, incentiva os alunos a aprofundar os seus estudos, n o só em rela o aos factores intervenientes no crescimento, mas também nas áreas científicas que partilham o interesse por este tema, seja ele por aspectos ligados à purifica o, produ o, caracteriza o, ou ao estudo de propriedades apetecíveis para aplica es tecnológicas. Nesta publica o resume-se o método experimental nas suas principais componentes: o que usar como suporte; quais as substancias que cristalizam com facilidade e qual o interesse do seu estudo; qual a técnica apropriada em cada caso; que reac es ou outros efeitos se estabelecem entre as substancias e os suportes. Finalmente, ao fazer um levantamento do que tem sido feito, interessa-nos salientar as suas potencialidades no campo do empreendorismo. Como complemento do trabalho experimental sugere-se a explora o de conceitos da química descritiva dos elementos, especialmente a dos metais, o que a torna muito menos árida e susceptível de memoriza o, pois os alunos ao come arem as suas colec es de substancias cristalinas, têm tendência a catalogar as suas propriedades físicas e químicas, as suas fórmulas e estruturas. Curiosamente, o método foi testado pela primeira vez em 1993, numa aula de Laboratório de Química Geral de Engenharia de Materiais. Por raz es históricas e n o só, achamos curial a sua publica o na área de Materiais. Crystals are of an increasing importance in our Society.
