Poly(ethylenedioxythiophene) (PEDOT) films were electrodeposited galvanostatically from an EDOT/sodium dodecyl sulfate solution in water, through a carboxylated polystyrene template monolayer self-assembled on ITO, after which the template was dissolved away in tetrahydrofuran. Analysis of the films by scanning electron microscopy and atomic force microscopy reveals large-area PEDOT honeycomb structures. The morphology of these structures was varied electrochemically, as the effective thickness and, surprisingly, the shape of the honeycomb arrangement depend on the polymerization time. Using nanospheres of 1 μm diameter and charge densities between 12 and 30 mC cm(-2) for electrodeposition generates PEDOT hexagons with very thin rectilinear walls 30-35 nm-thick and 800 nm-long, whereas at higher charge densities, circular bowls are created with 60 nm walls separating adjacent bowls; triangular areas as small as 0.02 μm(2) develop at the intersection of three nanospheres. These morphologies are specific to the use of carboxylated PS spheres and a water-based solution with a surfactant in the galvanostatic electrodeposition mode. Using smaller nanospheres, i.e. 500 nm in diameter, makes it possible to reach PEDOT hexagons with rectilinear walls as small as 11-17 nm-thick and 300 nm-long; circular bowls with 25-35 nm walls separating adjacent bowls and triangular areas as small as 0.003 μm(2) can also be generated. The wettabilities of the surfaces depend markedly on the pore depth of the PEDOT nanostructure, with contact angles going from 82° to 130° with increasing pore size. Finally these nanostructured PEDOT electrodes were used in Grätzel-type dye-sensitized solar cells (DSSCs) as Pt-free counter-electrodes, with an increase in the yield from 7.0 (bulk PEDOT) to 8.1%.Doxorubicin remains one of the most widely used chemotherapeutic agents however its effect on healthy tissue, such as skeletal muscle, remains poorly understood. The purpose of the current study was to examine the accumulation of doxorubicin (DOX) and its metabolite doxorubicinol (DOXol) in skeletal muscle of the rat up to 8 days after the administration of a 1.5 or 4.5 mg kg-1 i.p. dose. Subsequent to either dose, DOX and DOXol were observed in skeletal muscle throughout the length of the experiment. Interestingly an efflux of DOX was examined after 96 hours, followed by an apparent re-uptake of the drug which coincided with a spike and rapid decrease of plasma DOX concentrations. The interstitial space within the muscle did not appear to play a significant rate limiting compartment for the uptake or release of DOX or DOXol from the tissue to the circulation. Furthermore, there was no evidence that DOX preferentially accumulated in a specific muscle group with either dose. It appears that the sequestering of drug in skeletal muscle plays an acute and important role in the systemic availability and metabolism of DOX which may have a greater impact on the clinical outcome than previously considered.Fifty-six human and animal studies of cauda equina syndrome (CES) were reviewed. The evidence from human studies was poor (level IV). Evidence from animal studies and limited evidence from human studies suggest that structural and functional neurological losses are a progressive, continuous process. The longer the cauda equina nerve roots are compressed the greater the harm and the poorer the extent of recovery. This should prompt diagnosis and surgery for all CES patients as soon as practicably possible.The notions of a reaction path and a reaction coordinate are central to chemistry as they provide low-dimensional descriptions of complex molecular processes. Here we discuss how to define, compute, and use the reaction paths for chemical transformations in molecules that are subjected to mechanical stress and thus driven toward regions of conformational space that are otherwise inaccessible both in computational studies and in reality. We further show that the circuitous nature of mechanochemical pathways often makes their one-dimensional description impossible and describe how multidimensional effects can be detected experimentally.

Meconopsis horridula Hook (M. horridula) has been used as a traditional Tibetan medicine to relieve heat and pain as well as mobilize static blood, and it is recognized as a good treatment for bruises. This study is the first trial to evaluate the tumor inhibitory activity of M. horridula extract and its underlying mechanism in the hope of providing evidence to support the anticancer function of M. horridula.

M. horridula extract was cytotoxic to L1210 cells in a dose- and time-dependent manner. SEM (scanning electron microscope) observation revealed obvious morphological changes in L1210 cells after M. horridula treatment. Flow cytometry analysis demonstrated that the extract dose-dependently induced early apoptosis. Additional apoptosis parameters, such as alterations in nuclear morphology and DNA damage, were also observed. Furthermore, M. horridula treatment induced G2/M arrest. M. horridula treatment significantly increased reactive oxygen species (ROS) production, suggesting that ROS are a key factor in M. horridula-induced apoptosis. Volatile constituent detection found 15 abundant chemicals in M. horridula, which may contribute to its anticancer effect.

In conclusion, M. horridula extract induced L1210 cell apoptosis and inhibited proliferation through G2/M phase arrest, and ROS were involved in the process.

A challenging mirroring game service, which simultaneously provides game service to both PC and mobile phone users, allows them to play games against each other with very different control interfaces. Thus, for efficient mobile game design, it is essential to apply a new predictive model for measuring how potential touch input compares to the PC interfaces. The present study empirically tests the keystroke-level model (KLM) for predicting the time performance of basic interaction controls on the touch-sensitive smartphone interface (i.e., tapping, pointing, dragging, and flicking). A modified KLM, tentatively called the fingerstroke-level model (FLM), is proposed using time estimates on regression models.The experiment reported was set-up to investigate the space-time entropy of movement outcome as a function of a range of spatial (10, 20 and 30 cm) and temporal (250-2500 ms) criteria in a discrete aiming task. The variability and information entropy of the movement spatial and temporal errors considered separately increased and decreased on the respective dimension as a function of an increment of movement velocity. However, the joint space-time entropy was lowest when the relative contribution of spatial and temporal task criteria was comparable (i.e., mid-range of space-time constraints), and it increased with a greater trade-off between spatial or temporal task demands, revealing a U-shaped function across space-time task criteria. The traditional speed-accuracy functions of spatial error and temporal error considered independently mapped to this joint space-time U-shaped entropy function. The trade-off in movement tasks with joint space-time criteria is between spatial error and timing error, rather than movement speed and accuracy.Auditory verbal hallucinations (avh) are known to occur in relative isolation in various psychiatric disorders and as well in autism spectrum disorder (ASD). Up till now, research into the occurrence of auditory verbal hallucinations in patients who have a psychiatric disorder and ASD has been very limited. In order to give some indication about the effects of such a combination in one individual, we present a case-description of a 37-year-old man diagnosed with both pervasive developmental disorder--not otherwise specified (pdd-nos) and a mild intellectual disability. He was treated at the specialised outpatient 'Voices Clinic' of the University Hospital in Utrecht UMC. The patient responsed well treatment.Doctors dealing with patients who simultaneously have both psychiatric and somatic disorders often find themselves 'trapped' between two Dutch laws, the WBGO (the Law on the Medical Contract) and the Bopz (Law on Compulsory Admission to Psychiatric Hospitals). In order to illustrate a typical situation we present a case-study concerning a 50-year-old male with a probable seminoma testis and paranoid thoughts arising from an autistic disorder. The patient had refused the investigations and treatment that were considered necessary. Selleck Cyclopamine His compulsory attendance at the Court of Law and the adoption, by the doctors, of a multidisciplinary approach led to a successful outcome and patient satisfaction. We hope that the new Involuntary Mental Health Care Act (WvGGZ) will bridge the current gap between WGBO and the Bopz.

The document reporting Dutch mental health care negotiations for 2014-2017 calls for a cost decrease based on cost-effectiveness. Thanks to ROM, the Dutch mental health care seems well prepared for cost-effectiveness research.

Evaluate how valid cost-effectiveness research should be established in mental health care and the role of rom therein.

Evaluation of requirements of cost-effectiveness research, trends, and a translation to Dutch mental health care.

Valid cost-effectiveness research in mental health care requires the application of a societal perspective, a long time-horizon and an adequate evaluation of quality of life of patients. Healthcare consumption, outcome of care and characterisation of the patient population should be measured systematically and continuously. Currently, rom-data are not suitable to serve as a basis for cost-effectiveness research, although a proper basis is present. Further development of rom could lead to a situation in which mental health care is purchased on the basis of cost-effectiveness. However, cost-effectiveness will only really be improved if quality of care is rewarded, rather than rewarding activities that are not always related to outcome of care.

Cost-effectiveness research in mental health care should focus on societal costs and benefits, quality of life and a long time-horizon. If developed further, rom has the potential to be a basis for cost-effectiveness research in the future.

The high prevalence of psychiatric comorbidity is usually considered to be a problematic artefact of the DSM. Clinicians appear to be reluctant to register comorbid diagnoses.

To provide insight into the concept of 'psychiatric comorbidity', so that the phenomenon can be dealt with more efficiently in clinical practice.

We studied the literature and performed a theoretical analysis.

The high prevalence of psychiatric comorbidity is closely linked to the structure of the DSM and is leading increasingly to practical and theoretical problems. These problems have stimulated the development of several valuable alternative models of psychopathology. In the context of these developments, however, the use of terms such as 'artificial' has led to a needless and unfruitful polarisation of the debate. The debate needs to focus primarily on the usefulness of various models for patient care and research.

Psychiatric comorbidity is an inevitable consequence of a categorical approach to psychopathology, which is basically legitimate.
