[more ▼] OBJECTIVE: To use contrast-enhanced coded phase-inversion harmonic B-mode sonography to assess the acoustic enhancement of the synovial area of the knee; and to compare the data with the histological vessel density. METHODS: Eleven patients eligible for a knee arthroscopy were studied. Acoustic quantification was carried out by a digital image analysis program that detects the time-dependent increase [intensity (time) = k x time + C] of gray-level intensity in all the pixels of a specific region of interest (ROI) following intravenous injection of the microbubble contrast agent sulfur hexafluoride. Echo-guided synovial biopsies were carried out in the same ROI. Synovial vessel areas were quantified after Factor VIII immunostaining of synovial biopsies using an automated digital image analysis. RESULTS: Significant (p < 0.05) correlations were observed between histological vessel density and percentage of the synovial area with a k value > 0.01 (r = 0.93) and k(max) values (r = 0.79), as well as between the 2 latter parameters (r = 0.72). The histological vessel density and the 2 acoustic parameters were also significantly correlated with the logarithm of erythrocyte sedimentation rate (r = 0.77, r = 0.87, r = 0.67, respectively) and with log C-reactive protein serum concentration (r = 0.69, r = 0.83, r = 0.62, respectively). CONCLUSION: Contrast-enhanced coded phase-inversion harmonic B-mode sonography coupled with an appropriate data analysis method is a new tool to identify and quantify vessel density in knee synovitis.

[more ▼] Although both saproxylic longhorn beetles and hoverflies benefit from the presence of woody substrates for reproduction, they differ in their requirements for floral resources and for microbiotopes of overmature and senescent trees. This led us to expect contrasting responses between the two species groups in relation to these essential resources. We examined this prediction in 22 mature oak- and beech-dominated stands of southern Belgium by relating their species assemblages to local vegetation structure and composition, altitude and landscape composition. Stands were organised in pairs as a function of their overall dead wood supply. Free-hanging window traps, stump emergence traps and Malaise traps produced 30 longhorn beetle species (1637 individuals) and 106 hoverfly species (3020 individuals). Paired-comparisons controlling for annual variation in captures showed that, unlike saproxylic hoverflies, stands with dead wood hosted more species and individuals of longhorn beetles. Accordingly, the two species groups were found to be independent on ordination axes, responding to different sets of environmental conditions. While stands dominated by oaks with a high snag volume were highly favoured by longhorn beetles, saproxylic and threatened syrphids were limited to open-stands with large trees and a well-developed, species rich herb layer providing the floral resources required for their reproduction. Our results suggest that, when defining criteria to identify or restore important habitats for saproxylic insect conservation, variables related to different aspects of dead wood supply should not be the only criteria taken into account. © Springer 2006.

[more ▼] Brentano’s views on psychology influenced the way philosophy was made at the beginning of the 20th century. But did this influence spread as far as to give place to Freud’s revolutionary discovery of the psychoanalytical unconscious? We know that Sigmund Freud attended enthusiastically Brentano’s lectures between 1874 and 1876. Yet, since Brentano’s name is never mentioned in Freud’s later, properly psychoanalytical writings, there is a very convincing argument for stating that Brentano had no lasting influence on Freud. Furthermore, Freud’s theory of the unconscious doesn’t seem to continue, but rather to oppose Brentano’s psychological views. Yet, as it was shown lately by a number of philosophers there are reasons to believe that Brentano had a profound influence on Freud. An attentive analysis of Freud’s vocabulary as well as his arguments against “philosophical” objections supports this point rather convincingly. However, Freud was not a philosopher and Brentano’s historical influence does not suffice to transform the Freudian unconscious in a philosophical concept. It is the purpose of this paper to sketch a way to make a philosophical use of Freud’s unconscious by reconstructing the dialogue between Brentano and Freud on a conceptual level. First, I will explain the differences between Brentano and Freud’s psychology. While Brentano and even the most original of his students thought the mind is entirely conscious, and they only called “unconscious” certain intermittences of this consciousness, Freud’s metapsychology rests on the supposition that the mind is primarily unconscious and it is consciousness that appears locally as a quality of certain mental events. In the second part of my paper I will show that this opposition is not as radical as it seems. Freud’s metapsychological supposition of an unconscious mind is not merely stated but proven by clinical facts. And these facts allow Freud to substitute a dynamic approach of the mental to a descriptive psychology of Brentanian inspiration: a mental state is only conscious because it becomes thus by passing from an unconscious to a conscious state. It is this change in the point of view that allows Freud to see mental events as processes rather than mere states. Thus, the results of Brentano’s descriptive psychology are not denied but rather completed by Freud’s dynamic theory of the unconscious. The purpose of this paper is thus to clarify not only Freud’s historical relation to Brentano, but also the relation of his metapsychology to Brentano’s descriptive psychology and to all psychology that takes Freud’s discovery of the unconscious seriously. Despite the explicit critique of the unconscious that we find in the Psychology from an Empirical Standpoint, I think that Freud never truly opposed Brentano. He rather took Brentano’s descriptive psychology a step further: he introduced a dynamic component to the analysis of the psyche that could throw light on the blind spots in Brentano’s psychology.
