El cine cubano a lo largo de su existencia, por demás similar al resto de las distintas cinematografías a nivel mundial, se ha visto sometido a las más disímiles presiones tanto externas como internas, las cuales han ido dejando una profunda huella en el accidentado terreno que compone nuestra filmografía, dando pie a una periodización bastante evidente en consonancia con los distintos focos de influencia. Dos elementos distintos pero muy relacionados entre sí han condicionado los avatares y la calidad del cine cubano en cada momento de su historia. El primero de ellos, sin lugar a dudas, es el mercado interno cubano, demasiado pequeño como para recaudar lo invertido y obtener ganancias, sobre todo a partir de que las distribuidoras norteamericanas se adueñan de él, o ya en la época revolucionaria cuando el Estado descentralizó la recaudación como aparente medida de presión sobre el ICAIC. El segundo elemento condicionante resulta ser el capital que facilita los recursos para realizar los filmes y cómo este influye sobre ellos.

Patent foramen ovale and obstructive sleep apnoea are frequently encountered in the general population. Owing to their prevalence, they may coexist fortuitously; however, the prevalence of patent foramen ovale seems to be higher in patients with obstructive sleep apnoea. We have reviewed the epidemiological data, pathophysiology, and the diagnostic and therapeutic options for both patent foramen ovale and obstructive sleep apnoea. We focus on the interesting pathophysiological links that could explain a potential association between both pathologies and their implications, especially on the risk of stroke.

Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i) carcasses with larger biomass developed a higher abundance of flies and (ii) the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii) the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819). (iv) An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.
