Evaluating strategic environmental assessment in the Netherlands: Content, process and procedure as indissoluble criteria for effectiveness
To assess the effectiveness of strategic environmental assessment (SEA) we distinguish between its contribution to the quality of the ultimate policy choice (usefulness, applicability), the procedural quality of the planning process (transparency, timeliness) and the quality of stakeholder participation in the planning process (openness, equity, dialogue). In the context of two case studies involving Dutch planning practice, we argue that when and how an SEA is applied is crucial to understanding its e
Additional Value of CSF Amyloid-beta(40) Levels in the Differentiation between FTLD and Control Subjects
Quantification of amyloid-beta 40 in cerebrospinal fluid
Background: Truncated forms and full-length forms of the amyloid-beta 40 (Aβ40) are key molecules in the pathogenesis of dementia, and are detectable in CSF. Reliable methods to detect these biomarkers in CSF are of great importance for understanding the disease mechanisms and for diagnostic purposes. Methods: VU-α-Aβ40, a monoclonal antibody (mAb) specifically detecting Aβ40, was generated and characterized by solid and fluid phase ELISA, surface plasmon resonance spectroscopy (SPRS), immunoprecipitation (IP), immunohistochemical and Western blot (WB) analysis. In addition, an ELISA with VU-α-Aβ40 as catching and 6E10 as detecting mAbs was set up and validated. This ELISA was used to measure Aβ40 in CSF of controls (N = 27), patients with Alzheimer's disease (AD; N = 20), frontotemporal lobe dementia (FTLD; N = 14), noninflammatory (N = 15) and inflammatory (N = 15) neurological conditions. Results: VU-α-Aβ40 specifically recognizes Aβ40 with high affinity (

Kappa free light chains is a valid tool in the diagnostics of MS: A large multicenter study
Objective: To validate kappa free light chain (KFLC) and lambda free light chain (LFLC) indices as a diagnostic biomarker in multiple sclerosis (MS). Methods: We performed a multicenter study including 745 patients from 18 centers (219 controls and 526 clinically isolated syndrome (CIS)/MS patients) with a known oligoclonal IgG band (OCB) status. KFLC and LFLC were measured in paired cerebrospinal fluid (CSF) and serum samples. Gaussian mixture modeling was used to define a cut-off for KFLC and LFLC indexes. Results: The cut-off for the KFLC index was 6.6 (95% confidence interval (CI) = 5.2-138.1). The cut-off for the LFLC index was 6.9 (95% CI = 4.5-22.2). For CIS/MS patients, sensitivity of the KFLC index (0.88; 95% CI = 0.85-0.90) was higher than OCB (0.82; 95%CI = 0.79-0.85;p < 0.001), but specificity (0.83; 95% CI = 0.78-0.88) was lower (OCB = 0.92; 95% CI = 0.89-0.96;p < 0.001). Both sensitivity and specificity for the LFLC index were lower than OCB. Conclusion: Compared with OCB, the KFLC index is more sensitive but less specific for diagnosing CIS/MS. Lacking an elevated KFLC index is more powerful for excluding MS compared with OCB but the latter is more important for ruling in a diagnosis of CIS/MS
