Phenolic Compounds in Needles of Norway Spruce Trees in Relation to Novel Forest Decline I. Studies on Trees from a Site in the Northern Black Forest

1992

Summary Contents of selected phenolic compounds in needles of Norway spruce trees (Picea abies) from the Black Forest were measured using a HPLC-technique elaborated for serial studies in forest decline research. Measurements on needles that were harvested on several dates during two growing seasons gave no hint of seasonal variations in the concentrations of the studied phenolic compounds. Values for picein demonstrate an average decrease in the needles of severely damaged trees compared with the still undamaged ones, but the results are impaired by strong individual variations among the single trees. p-Hydroxyacetophenone was found in only very low amounts showing no constant differences …

Les pistes dinosauroïdes du Trias moyen français : interprétation et réévaluation de la nomenclature

2005

Resume De nombreuses traces de pieds dinosauroides, associees parfois avec la main, ont ete recoltees depuis 1960 dans les diverses formations greseuses de la base du Trias de la bordure orientale du Massif Central. Les niveaux a ichnites, dates par les donnees palynologiques, micropaleontologiques et palichnologiques sont compris dans l'intervalle Anisien-Ladinien inferieur. L'interpretation paleontologique de ces empreintes conduit a evoquer des Reptiles bipedes, digitigrades, aux membres posterieurs parasagittaux, ayant des mains pentadactyles et des pieds fontionnellement tridactyles II–IV, dont l'architecture osseuse est celle des Dinosaures Ceratosaures du Trias superieur. Les squelet…

Deux nouvelles traces de pas de Dinosaures du Trias supérieur de la bordure cévenole (la Grand-Combe, Sud-Est de la France)

2000

Resume Dans une formation sommitale a Argiles bariolees du Trias superieur francais, deux niveaux a traces depas inedites de Dinosaures ont ete decouverts. Elles se rapportent a l'association Otozoum/Grallator qui n'a jamais ete definie precisement en Europe. Sa position stratigraphique precise dans la serie triasique et la comparaison avec les associations ichnologiques des USA et d'Afrique du Sud, confirment l'âge Norien des niveaux a empreintes. Otozoum grandcombensis nov. ichnosp. correspond a des traces de pieds et de mains tetradactyles de meme taille, laissees par un animal bipede occasionnellement quadrupede. Il s'agissait probablement d'un, grand Prosauropode, d'une dizaine de m de…

Soluble liver antigen (SLA) antibody detection by ELISA and multiplexing technologies

2002

Abstract Objective: Develop and evaluate assays for the detection of antibodies to soluble liver antigen (SLA). SLA, also known as liver/pancreas antibody, was found to be 100% specific for autoimmune hepatitis (AIH) in a recent study of 2000 sera collected from individuals with various disease conditions and healthy individuals (Wies et al., Lancet 2000; 355:1510). Although SLA antibodies occur in only about 30% of patients with autoimmune hepatitis, they are found in some individuals with AIH who are negative for other autoantibodies. Methods: Specimens from patients with autoimmune hepatitis, non-autoimmune liver disease, various autoimmune conditions, as well as specimens from healthy i…

IL SUCCIACAPRE CAPRIMULGUS EUROPAEUS (Aves Caprimulgiformes) NIDIFICANTE ALLO STAGNONE DI MARSALA (TRAPANI)

The history of human-induced soil erosion: Geomorphic legacies, early descriptions and research, and the development of soil conservation—A global sy…

2013

Abstract This paper presents a global synopsis about the geomorphic evidence of soil erosion in humid and semihumid areas since the beginning of agriculture. Historical documents, starting from ancient records to data from the mid-twentieth century and numerous literature reviews form an extensive assortment of examples that show how soil erosion has been perceived previously by scholars, land surveyors, farmers, land owners, researchers, and policy makers. Examples have been selected from ancient Greek and Roman Times and from central Europe, southern Africa, North America, the Chinese Loess Plateau, Australia, New Zealand, and Easter Island. Furthermore, a comprehensive collection on the …

Type V collagen-induced upregulation of capn2 (large subunit of m-calpain) gene expression and DNA fragmentation in 8701-BC breast cancer cells

2011

Abstract Type V collagen is known to be over-deposited in the stroma of ductal infiltrating carcinomas of the breast. When used as a substrate, type V collagen restrains growth and invasion, and affects gene expression of 8701-BC ductal infiltrating carcinomas cells. Here we supplement existing data by demonstrating type V collagen dependent upregulation of capn2 gene expression in 8701-BC cells through differential display-PCR and Western blot assays. Furthermore, we suggest that our data obtained by centrifugal sedimentation and electrophoresis strongly suggest a correlation between calpain overproduction and DNA fragmentation, since the incubation with calpain inhibitor partly reverts th…

The Beginning of Western Greek Amphorae Production in Western Sicily: Archaeometric and Archaeological Studies on 6th–5th Centuries BCE Amphorae Manu…

2020

About 560 western Greek amphorae (6th–5th centuries BCE) re-used in enchytrismos burials were unearthed in the necropolis of the Dorian-Chalcidian colony of Himera in northwestern Sicily. Among the most striking issues is the determination of their geographical provenance. For this purpose, ceramic samples chipped from freshly broken surfaces of all the amphorae were first subdivided into macrofabrics by the use of a hand lens. Thereon, the samples were studied in accordance with standardized methods by the use of reflected light microscopy. Due to the special focus of our project on the characterization of Sicilian productions, a selection of amphorae which showed visible, macroscopic affi…
