Nowadays, more and more images are available. However, to find a required image for an ordinary user is a challenging task. Large amount of researches on image retrieval have been carried out in the past two decades. Traditionally, research in this area focuses on content based image retrieval. However, recent research shows that there is a semantic gap between content based image retrieval and...
To investigate the antinociceptive and anti-inflammatory activities of the denatured Naja Naja atra venom (NNAV) in rheumatoid arthritis-associated models, the denatured NNAV (heat treated; 30, 90, 270 μ g/kg), the native NNAV (untreated with heat; 90 μ g/kg), and Tripterygium wilfordii polyglycoside (TWP, 15 mg/kg) were administrated orally either prophylactically or therapeutically. We meas...
Despite several side effects, glucocorticoids (GCs) have been widely used for 60 y to treat rheumatoid arthritis on the basis of their antiinflammatory effects. However, the cells targeted by GCs and the transcriptional mechanisms underlying their actions through the glucocorticoid receptor (GR) in steroid therapy remain poorly defined. Using cell type-specific GR-deficient mice subjected to an...
The pathogenesis of aspirin (acetylsalicylic acid, ASA)-intolerant urticaria (AIU) is still poorly understood but it has recently been suggested that it is associated with the overproduction of leukotriene (LT). This is supported by evidence that cyclooxygenase 2 inhibitor is given safely to patients with AIU. The present study was designed to investigate the role of genetic polymorphism of LT ...
Cyclooxygenase-1 (COX-1) regulates the biosynthesis of prostaglandins, which are important mediators in asthma. The possible association of COX-1 gene polymorphisms with asthma has not been investigated. The allele frequencies of 20 COX-1 polymorphisms were determined in a random Australian Caucasian population using MassARRAY technology. Informative and potentially functional promoter (c.8592C...
Robotic operations are one of the major maintenance challenges for ITER and future fusion reactors. In particular, in vessel inspection operations without loss of conditioning will be mandatory. In this context, an Articulated Inspection Arm (AIA) has been developed by CEA within the European work programme framework, which aims at demonstrating the capabilities of a multi-purpose in-vessel Rem...
The coevolution of environment and living organisms is well known in nature. Here, it is suggested that similar processes can take place before the onset of life, where protocellular entities, rather than full-fledged living systems, coevolve along with their surroundings. Specifically, it is suggested that the chemical composition of the environment may have governed the chemical repertoire ge...
This work investigated the modulation by melatonin (Mel) of the effects of the porphyrinogenic drugs 2-allyl-2-isopropylacetamide (AIA) and 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-collidine (DDC) on oxidative environment, glucose biosynthesis and heme pathway parameters. Administration of Mel before rat intoxication with AIA/DDC showed a clear beneficial effect in all cases. Mel induced decrease...
In order to examine the hypothesis that in aspirin-induced asthma (AIA) cyclooxygenase inhibition is associated with enhanced release of leukotrienes (LTs), we measured urinary leukotriene E4 (LTE4) and 11-dehydro-thromboxane B2 (TXB2) (as a measure of cyclooxygenase production) following challenge with oral aspirin or inhaled methacholine, in 10 AIA patients. We also determined serum tryptase ...
