Predicting and managing the progression of structural damage in rheumatoid arthritis: where do we stand?
No full textThe editorial deals with a relevant issue regarding the radiographic damage progression in rheumatoid arthritis. Predictive factors and methods to assess radiographic damage such as conbventional radiology, ultrasonography, magnetic resonance and computed tomography, along with their advantages and limitations, are discussed in detail. More relevant trial which have yielded information on this issue are reviewed

Abstract
Verbena officinalis L. is used in folk medicine for the treatment of inflammatory disorders, skin burns, abrasions, and gastric diseases. Extracts obtained with different solvents (methanol, VoME; enriched flavonoids, VoEF; supercritical CO2, VoCO2) were evaluated for anti-inflammatory, gastroprotective and cicatrizing activities. Additionally, the antioxidant capacity was determined in vitro. In order to confirm the activities investigated, histological observations were performed. All extracts induce a remarkable anti-inflammatory activity. The gastric damage is significantly reduced by all extracts administered, whereby the most pronounced protection is observed for the VoCO2 and VoEF extracts. Finally, a wound healing effect is obtained particularly by the CO2 extract, suggesting the presence of some lipophilic active principles. Histological evidence confirms the results evaluated with the animal procedures. The results obtained after oral administration of V. officinalis extracts are also in agreement with the antioxidant capacity evaluated in vitro, confirming the relationship between pharmacological activities and antiradical efficacy

Optical surface photometry of radio galaxies II. Observations and data analysis
No full textAbstract. Optical imaging observations for 50 ra-dio galaxies are presented. For each object isophotal contours, photometric proles, structural parameters (position angle, ellipticity, Fourier coecients), and total magnitudes are given. These observations, obtained in the Cousins R band, complement the data presented in a previous paper and are part of a larger project aimed at studying the optical properties of low redshift (z 0:12) radio galaxies (Govoni et al. 1999). Comments for each individual source are reported

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
