Abstract: the goal of this study was to assess the growth of a four year-old nothofagus dombeyi, n. alpina and gevuina avellana plantation in san pablo de tregua, in the valdivian andes at c. 650 m of elevation. the plantation was established in eight strips 8-11 meter wide opened on a chusquea culeou thicket, a native bamboo species that has undergone massive die back after a mast flowering event in 2001. strips 1 through 6 were 37-74 m long, while strips 7 and 8 were 174 and 196 m long, respectively. old-growth forests formed the upper edge of the strips, while the lower edge was open grassland. strips were separated by 7-10 meters of untreated thicket, dominated by a dense mass of dead standing chusquea culms with a height of 8-11 m. mean annual increment (mai) in height and diameter at ground height were analyzed as a function of cover and distance to the untreated thicket between strips and to the forest edge. n. dombeyi survival and mai in height and diameter were higher at lower cover of the thicket between strips. n. alpina showed higher diameter mai when the cover of the thicket was <25%. this study concluded that plantations in strips for n. dombeyi that were tested show adequate survival and initial growth for ecologic restoration purposes in forests that have been logged and replaced by chusquea thickets.

Abstract: El objetivo de esta investigación fue evaluar el crecimiento de una plantación en fajas de cuatro a os de edad con las especies Nothofagus dombeyi (coigüe), N. alpina (raulí) y Gevuina avellana (avellano). El estudio se realizó en el fundo San Pablo de Tregua, ubicado en la Cordillera de Los Andes de la provincia de Valdivia, en ocho fajas de plantación confeccionadas después de una floración y muerte masiva ocurrida en un matorral de Chusquea culeou el a o 2001. Las fajas 1 a 6 presentaron longitudes de 37 a 74 m; y las fajas 7 y 8, 174 a 196 m, respectivamente. Los anchos de faja comprendieron 8 a 11 m. Mediante análisis de covarianza, de varianza y prueba t de Student se analizó el incremento medio anual (IMA) en altura y diámetro de cuello respecto de los factores: grado de cobertura de la interfaja, distancia a la misma y distancia al borde del bosque. Coigüe registró una sobrevivencia mayor al 90% en todas las fajas y presentó un mayor IMA en altura y diámetro de cuello en condiciones de mayor exposición al sol (P < 0,05). Raulí presentó diferencias significativas sólo en el IMA en diámetro de cuello creciendo más las plantas con una cobertura de interfaja menor a 25% (P < 0,05). Se concluyó que las plantaciones de coigüe en fajas resultaron adecuadas para su desarrollo inicial con objetivos de restauración ecológica, en bosques del tipo Coigüe-Raulí-Tepa degradados por tala con fines madereros. The goal of this study was to assess the growth of a four year-old Nothofagus dombeyi, N. alpina and Gevuina avellana plantation in San Pablo de Tregua, in the Valdivian Andes at c. 650 m of elevation. The plantation was established in eight strips 8-11 meter wide opened on a Chusquea culeou thicket, a native bamboo species that has undergone massive die back after a mast flowering event in 2001. Strips 1 through 6 were 37-74 m long, while strips 7 and 8 were 174 and 196 m long, respectively. Old-growth forests formed the upper edge of the strips, while the lower edge was open grassland. Strips were separated by 7-10 meters of untreated thicket, dominated by a dense mass of dead standing Chusquea culms with a height of 8-11 m. Mean annual increment (MAI) in height and diameter at ground height were analyzed as a function of cover and distance to the untreated thicket between strips and to the forest edge. N. dombeyi survival and MAI in height and diameter were higher at lower cover of the thicket between strips. N. alpina showed higher diameter MAI when the cover of the thicket was <25%. This study concluded that plantations in strips for N. dombeyi that w

Abstract: Cyclooxygenase-2 (COX-2) enzyme has been involved in the tumorigenesis and in the progression of colorectal cancer (CRC). The use of traditional nonsteroidal anti-inflammatory drugs (NSAIDs) or selective COX-2 inhibitors has been proposed for the prevention and the treatment of this relevant neoplastic disease. In the light of an innovative alternative to these pharmacological approaches, we review here the possible strategies to achieve a strong and selective inhibition of COX-2 enzyme by using the mechanism of RNA Interference (RNAi) targeted against its mRNA. Anti-COX-2 siRNA molecules (siCOX-2) can be generated in CRC cells from short hairpin RNA (shRNA) precursors, delivered in vitro by a retroviral expression system, and induce a significant and stable silencing of overexpressed COX-2 in human colon cancer cells. As a safer alternative to viral approach, nonpathogenic bacteria (E. coli) can be engineered to invade eukaryotic cells and to generate siCOX-2 molecules in cancer cells. Moreover, the involvement of miRNAs in COX-2 posttranscriptional regulation opens up the possibility to exploit an endogenous silencing mechanism to knockdown overexpressed COX-2. Thus, these recent strategies disclose new challenging perspectives for the development of clinically compatible siRNA or miRNA capable of selectively inhibiting COX-2 enzyme.

Abstract: Pietro Torelli, archivista, storico del diritto, storico della società, rappresenta una figura insieme importante ed “enigmatica” negli studi sul Medioevo italiano della prima metà del Novecento: i suoi contributi più significativi, dagli studi accursiani all’incompiuta opera sul comune mantovano, hanno lasciato infatti una traccia complessa nella tradizione storiografica nazionale. Pietro Torelli has been an archivist and a scholar of the juridical and social history of Middle Ages. He still stands as a figure both important and “enigmatic” in the Italian medieval research of the first half of the twentieth century: spanning from the fine analysis of Accursius’ Glossa to the unfinished masterpiece on the commune of Mantova, his most significant contributions have left a still complex and sometimes controversial trace in the Italian historiographical tradition.
