Medical students’ perception of general practice:a cross-sectional survey
Background: An increase in the demand for general practitioners is expected in many countries, but only a minority of medical students consider a career in general practice. More detailed and up-to-date knowledge about medical student’s perception of general practice would be helpful for efforts to encourage medical students to consider a career in general practice. Methods: We performed a cross-sectional single center survey among Dutch medical students to evaluate their perception of general practice at three different stages in their study: Ba1: first-year bachelor students; Ba3: third-year bachelor students; Ma3: third-year master students. The impact of different factors on their attitudes and perceptions was quantified. A multivariate logistic regression was performed with ‘interest in general practice’ as the outcome variable. Results: The median age for Ba1 was 18 (IQR: 18–19) and 71.5% were female, for Ba3 the median age was 20 (IQR: 20–21) and 70.6% were female and for Ma3 the median age was 25 years (IQR: 24–26) and 73.3% were female. On average, 31.2% of the respondents had a migration background. The mean response rate for this study was 77.1%. Of the participating Ba1 students (n = 340) only 22.4% considered working as a GP after medical school; for Ba3 students (n = 231) this percentage was 33.8%, and for Ma3 students (n = 210) it was significantly higher at 70.5%; in the final multivariate model this corresponded to an odds ratio (OR) of 4.3 (95%-CI:2.6–6.9) compared to Ba1 students. The strongest predictor in the final model was the opinion that general practice provides a pleasant working environment (OR 9.5; 95%-CI: 6.2–14.5). Conclusion: This study showed that multiple factors are significantly related to medical students’ interest in general practice. Although students believed that general practice does not have a high status within the medical profession, they acknowledged the social importance and the pleasant working environment of general practice. Knowledge obtained in this study can be used when designing a medical curriculum or a general practice course.</p
Leren van het energieke platteland : lokale en regionale coalities voor duurzame plattelandsontwikkeling
In deze studie onderzoeken we de kracht van de samenwerking tussen de verschillende gebruikers van het platteland. Burgers, boeren, natuurbeheerders en bedrijven die samen initiatieven ontplooien om hun leefomgeving te verbeteren. De studie laat aan de hand van een breed scala aan praktijkvoorbeelden zien hoe ze dat doen, wat ze proberen te bereiken en waar ze tegenaan lopen. Zo zijn er moderne boeren die samen met andere ketenpartijen hun bedrijfsvoering nog verder willen verduurzamen dan de wet al voorschrijft, en burgers die met boeren lokale coöperaties opzetten voor de opwekking van hernieuwbare energie
Measurement of Z0 decays to hadrons, and a precise determination of the number of neutrino species
We have made a precise measurement of the cross section for e+e--->Z0-->hadrons with the L3 detector at LEP, covering the range from 88.28 to 95.04 GeV. From a fit to the Z0 mass, total width, and the hadronic cross section to be MZ0=91.160 +/- 0.024 (experiment) +/-0.030(LEP) GeV, [Gamma]Z0=2.539+/-0.054 GeV, and [sigma]h(MZ0)=29.5+/-0.7 nb. We also used the fit to the Z0 peak cross section and the width todetermine [Gamma]invisible=0.548+/-0.029 GeV, which corresponds to 3.29+/-0.17 species of light neutrinos. The possibility of four or more neutrino flavors is thus ruled out at the 4[sigma] confidence level.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28683/3/0000500.pd
A measurement of the Z0 leptonic partial widths and the vector and axial vector coupling constants
We have measured the partial widths of the Z0 into lepton pairs, and the forward-backward charge asymmetry for the process e+e--->[mu]+[mu]- using the L3 detector at LEP. We obtain an average [Gamma]ll of 83.0+/-2.1+/-1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z0 to leptons: grmv=-0.066-0.027+0.046 and grmA= -0.495-0.007+0.007.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28666/3/0000483.pd
Effects of tryptophan depletion on carbon dioxide provoked panic in panic disorder patients
Results of an earlier study in healthy volunteers suggest that the serotonergic system is involved in anxiety-related mechanisms. We studied the influence of tryptophan depletion on the response to a 35% carbon dioxide challenge. Twenty-four panic disorder patients received a mixture of amino acids, either with or without tryptophan, under double-blind conditions. There was a significant increase in anxiety as well as in neurovegetative symptoms in the depletion group, compared to the placebo condition. Furthermore, when we compare the results of the placebo group with earlier panic provocation studies, it also seems that a balanced amino acid mixture might have a protective effect against a panic provocation. We conclude that the panic-enhancing effect of tryptophan depiction as well as the potential protective effect of tryptophan administration in panic disorder patients can be explained by the Deakin-Graeff theory of anxiety

Development of a First-in-Class Small Molecule Inhibitor of the C-terminal Hsp90 Dimerization
Heat shock protein 90 (Hsp90) is a promising therapeutic target due to its involvement in stabilizing several aberrantly expressed oncoproteins. In cancerous cells, Hsp90 expression is elevated, thereby contributing in exerting anti-apoptotic effects, which is essential for the malignant transformation and progression of several tumor types. Most of the Hsp90 inhibitors (Hsp90i) under investigation target the ATP binding site in the N-terminal domain (NTD) of Hsp90. However, adverse effects, including induction of the pro-survival resistance mechanism (heat shock response or HSR) and associated dose-limiting toxicity, have so far precluded clinical approval of these Hsp90i. In contrast, modulators that interfere with the C-terminal domain (CTD) of Hsp90 do not inflict HSR and, thus, emerge as a promising alternative approach to target Hsp90. Since the CTD dimerization of Hsp90 is essential for its chaperone activity, interfering with this essential dimerization process by small-molecule protein-protein interaction (PPI) inhibitors is a promising strategy for anticancer drug research. We have developed the first-in-class small molecule inhibitor (5b) targeting the Hsp90 CTD dimerization interface, based on a tripyrimidonamide scaffold through structure-based molecular design, chemical synthesis, binding mode model prediction, assessment of the biochemical affinity and efficacy against therapy-resistant leukemia cells. 5b reduces xenotransplantation of leukemia cells in zebrafish models and induces apoptosis in BCR-ABL1+ (T315I) tyrosine kinase inhibitors (TKIs) resistant leukemia cells, without inducing HSR
