La escena del campo de batalla tras el enfrentamiento entre pompeyanos y cesarianos en el libro VII del Bellum Ciuile de Lucano (786-846) deja al descubierto el proceso de refuncionalización del tópico tradicional del día después de la lucha. Desde una perspectiva estilística mostramos que la intersección entre los códigos historiográfico, épico y trágico y la manipulación de diversos motivos literarios y culturales en dicho relato pueden leerse como uno de los principales mecanismos de la poética lucaniana del ciuile nefas.

A pollen diagram from the Ahlequellmoor in the Solling area shows the history of vegetation and settlement over the last 7,800 years. In the early Atlantic period mixed deciduous forest with mainly Tilia together with Ulmus and Quercus grew in the area. In the late Atlantic period Quercus became most abundant. Fagus spread in the Sub-boreal period at about 2700 B.C. Since ca. 900 B.C. the Solling was covered by beech forests with some oak. In prehistoric times woodland grazing is indicated. Only in Medieval times are two settlements in the vicinity of the Ahlequellmoor reflected in the pollen diagram. The earlier one is dated to about A.D. 750-1020, and may be connected with the former Monastery of Hethis, which is thought to have existed close to the fen from A.D. 815 to 822. The second Medieval settlement dates to the 11th-12th century. The large-scale woodland destruction of late Medieval and modern times is not clearly visible. The silvicultural measures of the last 200 years are reflected by increasing values of spruce and grassland taxa.

A palynological investigation of a Holocene profile from Lake Voulkaria, western Greece, was carried out as a contribution to the environmental history of the coastal area of northwestern Acarnania and the Classical city of Palairos. It shows that deciduous oaks dominated the natural vegetation of the area throughout the Holocene. Until ca. 7000 B.C. Pistacia occurred abundantly, while other evergreen woody taxa were rare. At ca. 6300 B.C. an expansion of Carpinus orientalis/Ostrya can be observed. Around ca. 5300 B.C. spreading of Erica indicates a change to a drier climate and/or first human impact. Since ca. 3500 B.C. an increase of evergreen shrubs now clearly indicates land-use. The foundation of the Classical city of Palairos led to a temporary expansion of Phillyrea maquis. Within this period, molluscs of brackish water indicate the use of the lake as a harbour after the construction of a connection to the sea. The deciduous Quercus woodland recovered when human impact decreased in the area, and lasted until modern times.

Human c-sis/PDGF-B proto-oncogene has been shown to be overexpressed in a large percentage of human tumor cells establishing a growth-promoting, autocrine growth circuit. Triplex forming oligonucleotides (TFOs) can recognize and bind sequences in duplex DNA, and have received considerable attention because of their potential for targeting specific genomic sites. The c-sis/PDGF-B promoter contains a unique homopurine/homopyrimidine sequence (SIS proximal element, SPE), which is crucial for binding nuclear factors that provoke transcription. In order to develop specific transcriptional inhibitors of the human c-sis/PDGF-B proto-oncogene, 20 potential TFOs targeting part or all of the SPE were screened by gel mobility analysis. DNase I footprinting shows that the TFOs we designed can form a sequence-specific triplex with the target. Protein binding assays demonstrate that triplex formation inhibits nuclear factors binding the c-sis/PDGF-B promoter. Both transient and stable transfection experiments demonstrate that the transcriptional activity of the promoter is considerably inhibited by the TFOs. We propose that TFOs represent a therapeutic potential to specifically diminish the expression of c-sis/PDGF-B proto-oncogene in various pathologic settings where constitutive expression of this gene has been observed.
