Uit de oude doos: De reizen der B.I.L.

Ieder jaar opnieuw organiseert de B.I.L. weer twee reizen voor de reislustige studenten onder ons. Dit jaar is er ook weer de Masterreis voor de masterstudenten die verdieping in de praktijk zoeken naast hun studie of zich misschien willen oriënteren op een carrière in het buitenland. Hoog tijd om eens in de geschiedenisboeken te duiken wanneer en waar deze traditie startte en vandaan komt

How to diagnose plantaris tendon involvement in midportion Achilles tendinopathy - clinical and imaging findings

Background: The purpose of this investigation was to evaluate if clinical assessment, Ultrasound + Colour Doppler (US + CD) and Ultrasound Tissue Characterisation (UTC) can be useful in detecting plantaris tendon involvement in patients with midportion Achilles tendinopathy. Methods: Twenty-three tendons in 18 patients (14 men, mean age: 37 years and 4 women: 44 years) (5 patients with bilateral tendons) with midportion Achilles tendinopathy were surgically treated with a scraping procedure and plantaris tendon removal. For all tendons, clinical assessment, Ultrasound + Colour Doppler (US + CD) examination and Ultrasound Tissue Characterisation (UTC) were performed. Results: At surgery, all 23 cases had a plantaris tendon located close to the medial side of the Achilles tendon. There was vascularised fat tissue in the interface between the Achilles and plantaris tendons. Clinical assessment revealed localised medial activity-related pain in 20/23 tendons and focal medial tendon tenderness in 20/23 tendons. For US + CD, 20/23 tendons had a tendon-like structure interpreted to be the plantaris tendon and localised high blood flow in close relation to the medial side of the Achilles. For UTC, 19/23 tendons had disorganised (type 3 and 4) echopixels located only in the medial part of the Achilles tendon indicating possible plantaris tendon involvement. Conclusions: US + CD directly, and clinical assessment indirectly, can detect a close by located plantaris tendon in a high proportion of patients with midportion Achilles tendinopathy. UTC could complement US + CD and clinical assessment by demonstrating disorganised focal medial Achilles tendon structure indicative of possible plantaris involvement

Masterreis

In de vroege morgen van maandag 8 april verzamelden een groep masterstudenten zich voor een tweedaagse reis naar de hoofdstad van de Europese Unie: Brussel. Lees hieronder over de reis, hoe ze Brussel hebben ervaren en welke instanti es ze hebben bezocht

POPULATION DYNAMICS AND SPAWNING OF THE FLATFISH SOLEA BLEEKERI AND PSEUDORHOMBUS ARSIUS IN THE INTERTIDAL AREA OF INHACA ISLAND, MO&#199AMBIQUE

The population dynamics of flatfish Solea bleekeri and Pseudorhombus arsius within the intertidal area of Inhaca Island, Moçambique, was investigated using bottom trawl data collected during summer (December 1996–March 1997) and winter (June 1997–August 1997). The endemic S. bleekeri is a small, relatively slowgrowing species with low rates of natural mortality. Densities of juveniles were significantly greater in winter (24.7 fish 1 000 m-2) than in summer (10.8 fish 1 000 m-2), probably because of intensive spawning during summer. Greater catches of S. bleekeri were taken by night than by day. Densities of P. arsius did not differ significantly between day and night or among seasons. Mean density of P. arsius was 53 fish 1 000 m-2 for the survey. Both species preferred the same substrata, significantly greater densities being found on the mudflats and in the tidal channels. Both seem to complete two life cycles within a year.Afr. J. mar. Sci. 25: 49–6

Tomato linalool synthase is induced in trichomes by jasmonic acid

Tomato (Lycopersicon esculentum) plants emit a blend of volatile organic compounds, which mainly consists of terpenes. Upon herbivory or wounding, the emission of several terpenes increases. We have identified and characterized the first two tomato monoterpene synthases, LeMTS1 and LeMTS2. Although these proteins were highly homologous, recombinant LeMTS1 protein produced (R)-linalool from geranyl diphosphate (GPP) and (E)-nerolidol from farnesyl diphosphate (FPP), while recombinant LeMTS2 produced β-phellandrene, β-myrcene, and sabinene from GPP. In addition, these genes were expressed in different tissues: LeMTS1 was expressed in flowers, young leaves, stems, and petioles, while LeMTS2 was strongest expressed in stems and roots. LeMTS1 expression in leaves was induced by spider mite-infestation, wounding and jasmonic acid (JA)-treatment, while LeMTS2 did not respond to these stimuli. The expression of LeMTS1 in stems and petioles was predominantly detected in trichomes and could be induced by JA. Because JA treatment strongly induced emission of linalool and overexpression of LeMTS1 in tomato resulted in increased production of linalool, we propose that LeMTS1 is a genuine linalool synthase. Our results underline the importance of trichomes in JA-induced terpene emission in tomato

De vele dimensies van Europa

Er wordt op verschillende niveaus politiek bedreven: regionaal, nationaal en internationaal, met elk zijn eigen eigenschappen en actoren. Vaak is de nationale politiek bekender bij de Nederlandse burger, terwijl de internationale politiek, met name de Europese politiek, net zo belangrijk is, zo niet belangrijker. Sinds juli 2004 neemt Sophie in ´t Veld namens D66 zitting in het Europees Parlement. We hebben haar gevraagd ons een inzicht te geven in de politiek op Europees niveau

Het Huis van Thorbecke: Tijd voor een verbouwing?

In de periode 1750 - 1850 hebben er belangrijke bestuurlijke veranderingen plaatsgevonden, die nog steeds van belang zijn voor onze maatschappij. Een van de grootste is wel de grondwet van Thorbecke van 1848. Het huidige Nederlandse insti tuti onele bestel komt voort uit zijn Grondwet, Gemeentewet en Provinciewet. Deze bestuurlijke organisati e met de drie bestuurslagen Rijk, provincie en gemeente wordt alsmede het Huis van Thorbecke genoemd (parlement.com). Aan de hand van interviews met docenten van Bestuurskunde proberen we er achter te komen hoe belangrijk Thorbecke is voor het Openbaar Bestuur en in hoeverre het systeem toe is aan veranderingen

Lateral Eye Movements Do Not Increase False-Memory Rates: A Failed Direct-Replication Study

In this direct replication of Houben, Otgaar, Roelofs, and Merckelbach (Clinical Psychological Science, 6, 610–616, 2018), we tested whether making eye movements during memory recall increases susceptibility to creating false memories. Undergraduates (N = 206) watched a video of a car crash, after which they recalled the video with or without simultaneously making eye movements. Next, participants received misinformation about the video. Finally, during the critical test, they were questioned about video details. The results showed that making eye movements did not increase endorsement of misinformation (i.e., false memory), nor did it reduce (correct) memory details or memory vividness and emotionality. Random variation in sampling or measurement, low reliability of the test instrument, and observer-expectancy effects may explain discrepancies between study effects. Only multiple direct replications by different (independent) laboratories with standardized instruments will allow for assessing whether the effect is robust and largely independent of random variation and moderators
