larvae strain. Chloroform extracts (CE) and ethyl ether extracts (ETE) from F. riparia and ETE from F. fiebrigii were most active against P. larvae Azul, the most sensitive indicator strain with MIC values of 250 ppm (CE) and 2000 ppm (ETE) for F. riparia, and 2500 ppm (ETE) for F. fiebrigii. Hexane extracts from the three species

did not present any significant GF120918 clinical trial inhibitory effect. These results would indicate that one or some of the more polar compounds would cause inhibition of this pathogen. Toxicity assays demonstrated that even the highest concentrations assayed (125,000 ppm) did not show lethal effects on exposed bees during in vitro conditions. (C) 2013 Elsevier B.V.

“Objective: LCL161 To develop a semiquantitative MRI-based scoring system (HOAMS) of hip osteoarthritis (OA) and test its reliability and validity.

Design:

Fifty-two patients with chronic hip pain were included. 1.5T magnetic resonance imaging (MRI) was performed on all patients. Pelvic radiographs were scored according to the Kellgren-Lawrence (KL) system. Clinical outcomes were assessed by the hip osteoarthritis outcome score (HOOS). MRIs were analyzed using a novel whole-joint MRI score that incorporated 13 articular features. Reliability was determined on a random subset of 15 cases. Weighted-kappa statistics and overall agreement were used as a measure of intra- and inter-observer reliability. Associations between MRI features and radiographic OA severity were calculated using Cochran-Armitage test for trend. Ordinal logistic regression was used to assess associations between MRI features and severity

of pain and functional limitation.

Results: Distribution of radiographic grading was: KL 0 = 12 (27%), KL 1=11 (25%), KL 2 = 14 (32%), KL 3 = 5 (11%) and KL 4 = 2 (5%). Intra-reader selleck compound reliability for the different features ranged from 0.18 (cysts) to 0.85 (cartilage). Inter-reader reliability ranged between 0.15 (cysts) and 0.85 (BMLs). Low kappas were due to low frequencies of some features as overall percent agreement was good to excellent (83.8% and 83.1%). There was a strong association between MRI-detected lesions and radiographic severity (P=0.002). Non-significant trends were observed between MRI features and clinical outcomes.

Conclusion: MRI-based semiquantitative assessment of the hip shows adequate reliability. Presence of more severe MRI-detected intraarticular pathology shows a strong association with radiographic OA. The results suggest possible associations between MRI-detected pathology and clinical symptoms. (C) 2011 Osteoarthritis Research Society International. Published by Elsevier Ltd.
