Study of light-induced MscL gating by EPR spectroscopy.
Yilmaz D, Dimitrova AI, Walko M, Kocer A
A number of techniques developed to investigate protein structure and function depend on chemically modifying and/or labeling of proteins. However, in the case of homooligomeric proteins, the presence of multiple identical subunits obstructs the introduction of residue-specific labels to only one or several subunits, selectively. Here, in order to study the initial conformational changes of a homopentameric mechanosensitive ion channel during its gating, we developed a method for labeling a defi...

Adding mindfulness-based cognitive therapy to maintenance antidepressant medication for prevention of relapse/recurrence in major depressive disorder: Randomised controlled trial.
Huijbers MJ, Spinhoven P, Spijker J, Ruhé HG, van Schaik DJ, van Oppen P, Nolen WA, Ormel J, Kuyken W, van der Wilt GJ, Blom MB, Schene AH, Donders AR, Speckens AE
Background: Mindfulness-based cognitive therapy (MBCT) and maintenance antidepressant medication (mADM) both reduce the risk of relapse in recurrent depression, but their combination has not been studied. Our aim was to investigate whether the addition of MBCT to mADM is a more effective prevention strategy than mADM alone. Methods: This study is one of two multicenter randomised trials comparing the combination of MBCT and mADM to either intervention on its own. In the current trial, recurrentl...

Viral metagenomics in drug-naïve, first-onset schizophrenia patients with prominent negative symptoms.
Canuti M, van Beveren NJ, Jazaeri Farsani SM, de Vries M, Deijs M, Jebbink MF, Zaaijer HL, van Schaik BD, van Kampen AH, van der Kuyl AC, de Haan L, Storosum JG, van der Hoek L
Although several studies suggest a virus or (endogenous) retrovirus involvement at the time of onset of schizophrenia, the unequivocal identification of one or more infectious agents, by means of an undirected catch-all technique, has never been conducted. In this study VIDISCA, a virus discovery method, was used in combination with Roche-454 high-throughput sequencing as a tool to determine the possible presence of viruses (known or unknown) in blood of first-onset drugs-naïve schizophrenic pat...

Comparison of Changes in Global Longitudinal Peak Systolic Strain After ST-Segment Elevation Myocardial Infarction in Patients With Versus Without Diabetes Mellitus.
Hoogslag GE, Abou R, Joyce E, Boden H, Kamperidis V, Regeer MV, van Rosendael PJ, Schalij MJ, Bax JJ, Marsan NA, Delgado V
Global longitudinal strain (GLS) measured by 2-dimensional longitudinal speckle-tracking echocardiography may be a more sensitive measure of left ventricular (LV) mechanics than conventional LV ejection fraction (EF) to characterize adverse post-ST-segment elevation myocardial infarction (STEMI) remodeling. The aim of the present evaluation was to compare changes in LV GLS in patients with versus without diabetes after the first STEMI. Patients with first STEMI and diabetes (n = 143; age 64 ± 12...

4β-hydroxycholesterol as an endogenous CYP3A marker in cancer patients treated with taxanes.
de Graan AJ, Sparreboom A, de Bruijn P, de Jonge E, van der Holt B, Wiemer EA, Verweij J, Mathijssen RH, van Schaik RH
Aim: Taxanes are anti-cancer agents used to treat several types of solid tumours. They are metabolized by cytochrome P450 (CYP) 3A, displaying a large pharmacokinetic (PK) variability. In this study, we evaluated the endogenous CYP3A4 marker 4β-hydroxycholesterol (4β-OHC) as a potential individual taxane PK predictor. Methods: Serum 4β-OHC and cholesterol concentrations were determined in 291 paclitaxel and 151 docetaxel-treated patients, and were subsequently correlated with taxane clearance. R...

Fast, Simple and Accurate Handwritten Digit Classification by Training Shallow Neural Network Classifiers with the 'Extreme Learning Machine' Algorithm.
McDonnell MD, Tissera MD, Vladusich T, van Schaik A, Tapson J
Recent advances in training deep (multi-layer) architectures have inspired a renaissance in neural network use. For example, deep convolutional networks are becoming the default option for difficult tasks on large datasets, such as image and speech recognition. However, here we show that error rates below 1% on the MNIST handwritten digit benchmark can be replicated with shallow non-convolutional neural networks. This is achieved by training such networks using the 'Extreme Learning Machine...

Loss of Antibiotic Tolerance in Sod-Deficient Mutants Is Dependent on the Energy Source and Arginine Catabolism in Enterococci.
Ladjouzi R, Bizzini A, van Schaik W, Zhang X, Rincé A, Benachour A, Hartke A
Unlabelled: Enterococci are naturally tolerant to typically bactericidal cell wall-active antibiotics, meaning that their growth is inhibited but they are not killed even when exposed to a high concentration of the drug. The molecular reasons for this extraordinary tolerance are still incompletely understood. Previous work showed that resistance to killing collapsed specifically in mutants affected in superoxide dismutase (Sod) activity, arguing that bactericidal antibiotic treatment led to indu...

Stopping antiplatelet medication before coronary artery bypass graft surgery: is there an optimal timing to minimize bleeding?
Gielen CL, Bruggemans EF, Stijnen T, Eikenboom J, Tavilla G, Brand A, Klautz RJ
Objectives: As the indication for antiplatelet medication expands, patients may be exposed to an increased risk of excessive blood loss when cardiac surgery is required. The optimal timing to stop acetylsalicylic acid (ASA) or ASA combined with clopidogrel (ASA+Clo) before surgery is the subject of controversy. Methods: A total of 1065 patients were selected from a prospective randomized study on the effect of a fibrin sealant application in coronary artery bypass graft surgery [Fibrin sealant I...

Optimisations and Challenges Involved in the Creation of Various Bioluminescent and Fluorescent Influenza A Virus Strains for In Vitro and In Vivo Applications.
Spronken MI, Short KR, Herfst S, Bestebroer TM, Vaes VP, van der Hoeven B, Koster AJ, Kremers GJ, Scott DP, Gultyaev AP, Sorell EM, de Graaf M, Bárcena M, Rimmelzwaan GF, Fouchier RA
Bioluminescent and fluorescent influenza A viruses offer new opportunities to study influenza virus replication, tropism and pathogenesis. To date, several influenza A reporter viruses have been described. These strategies typically focused on a single reporter gene (either bioluminescent or fluorescent) in a single virus backbone. However, whilst bioluminescence is suited to in vivo imaging, fluorescent viruses are more appropriate for microscopy. Therefore, the idea l reporter virus varies dep...

Ticagrelor or prasugrel versus clopidogrel in elderly patients with an acute coronary syndrome: Optimization of antiplatelet treatment in patients 70 years and older--rationale and design of the POPular AGE study.
Qaderdan K, Ishak M, Heestermans AA, de Vrey E, Jukema JW, Voskuil M, de Boer MJ, van't Hof AW, Groenemeijer BE, Vos GJ, Janssen PW, Bergmeijer TO, Kelder JC, Deneer VH, ten Berg JM
Rationale: Dual antiplatelet therapy with acetylsalicylic acid in combination with a more potent P2Y12- inhibitor (ticagrelor or prasugrel) is recommended in patients with acute coronary syndrome without ST-segment elevation (NSTE-ACS) to prevent atherothrombotic complications. The evidence on which this recommendation is based shows that ticagrelor and prasugrel reduce atherothrombotic events at the expense of an increase in bleeding events when compared with clopidogrel. However, it remains un...

Serum Cardiac Troponin-I is Superior to Troponin-T as a Marker for Left Ventricular Dysfunction in Clinically Stable Patients with End-Stage Renal Disease.
Buiten MS, de Bie MK, Rotmans JI, Dekker FW, van Buren M, Rabelink TJ, Cobbaert CM, Schalij MJ, van der Laarse A, Jukema JW
Background: Serum troponin assays, widely used to detect acute cardiac ischemia, might be useful biomarkers to detect chronic cardiovascular disease (CVD). Cardiac-specific troponin-I (cTnI) and troponin-T (cTnT) generally detect myocardial necrosis equally well. In dialysis patients however, serum cTnT levels are often elevated, unlike cTnI levels. The present study aims to elucidate the associations of cTnI and cTnT with CVD in clinically stable dialysis patients. Methods: Troponin levels were...
