Structural considerations on the iridoids as anti-inflammatory agents.

1994

Abstract Twelve iridoid glycosides have been evaluated for their anti-inflammatory activity on two models: the carrageenan-induced mouse paw edema and the TPA-induced mouse ear edema. Loganic acid was the most active (44.4% edema inhibition) on the former test, whereas the catalpol derivative mixture isolated from Scrophularia, aucubin, verbenalin, and loganin, showed the highest activity (from 72.0 to 80.0% edema inhibition) on the latter. The results allowed us to establish the relationship between the structure and anti-inflammatory activity on the basis of the different patterns of substitution, particularly hydroxylation, unsaturation, and acylation.

Secoiridoids and Iridoids from Morinda asteroscepa

2020

The new 2,3-secoiridoids morisecoiridoic acids A (1) and B (2), the new iridoid 8-acetoxyepishanzilactone (3), and four additional known iridoids (4–7) were isolated from the leaf and stem bark methanol extracts of Morinda asteroscepa using chromatographic methods. The structure of shanzilactone (4) was revised. The purified metabolites were identified using NMR spectroscopic and mass spectrometric techniques, with the absolute configuration of 1 having been established by single-crystal X-ray diffraction analysis. The crude leaf extract (10 μg/mL) and compounds 1–3 and 5 (10 μM) showed mild antiplasmodial activities against the chloroquine-sensitive malaria parasite Plasmodium falciparum (…

Validation of the German version of the Kujala score in patients with patellofemoral instability : a prospective multi-centre study

2017

Introduction: The Kujala score is the most frequently used questionnaire for patellofemoral disorders like pain, instability or osteoarthritis. Unfortunately, we are not aware of a validated German version of the Kujala score. The aim of our study was the translation and linguistic validation of the Kujala score in German-speaking patients with patella instability and the assessment of its measurement characteristics. Materials and methods: The German Kujala score was developed in several steps of translation. In addition to healthy controls, the Kujala German was assessed in consecutive patients undergoing reconstruction of the medial patellofemoral ligament for recurrent patellar dislocat…

Un/doing calculation: on knowledge practices of risk management

2011

From small enterprises all the way up to financial markets, economic calculation is an activity routinely conducted in economic life-worlds. This paper argues that calculation is situated in the practice of participants involved in these life-worlds as well as in the technological tools they use. It champions a sociological analysis of the world-constituting character of calculation. As empirical examples the paper discusses risk management strategies, the embeddedness of calculation practices in banking infrastructure, and the process of internal rating procedures. Contesting the idea of the omnipresence of calculation, the paper analyzes the social phenomenon of the neutralization of calc…

New data on the early development of Hysterothylacium aduncum (Nematoda, Anisakidae).

1998

This note reports on incidental observations of the early development of the third-stage larvae of Hysterothylacium aduncum from gadid fishes. Gravid H. aduncum females were collected from Pollachius virens, Pollachius pollachius. Gadus morhua, and Molva molva in Norwegian waters. The eggs were incubated at 20 per thousand salinity and 5 C. Spontaneous hatching of third-stage larvae was observed 10-25 days after egg deposition. These larvae were long lived and could infect Acartia tonsa copepods, the infections being maintained for up to 34 days. The morphology of the third-stage larvae in the copepods and some traits of the life cycle were similar to those reported in previous studies. How…

Assessing learners’ writing skills in a SLA study: Validating the rating process across tasks, scales and languages

2014

There is still relatively little research on how well the CEFR and similar holistic scales work when they are used to rate L2 texts. Using both multifaceted Rasch analyses and qualitative data from rater comments and interviews, the ratings obtained by using a CEFR-based writing scale and the Finnish National Core Curriculum scale for L2 writing were examined to validate the rating process used in the study of the linguistic basis of the CEFR in L2 Finnish and English. More specifically, we explored the quality of the ratings and the rating scales across different tasks and across the two languages. As the task is an integral part of the data-gathering procedure, the relationship of task p…

Infrastructura Naturans. Architetture di trasformazione della circonvallazione di Palermo

2022

The article discusses the theoretical system that supports design themes and processes of recycling large urban road infrastructures, referring to an international research that frames them among the sustainable regeneration processes of the contemporary city, and further evoking the project for the transformation of Palermo's ring road that has been elaborated within this research. Witnesses of past urban seasons, these infrastructures are marked by a peculiar morphology that deserves to be maintained, while they must emancipate themselves from asphalt and adapt to new urban mobilities. By hybridizing vegetation and buildings as never before, the longest roadways in our urban contexts may …
