Confined water in the low hydration regime
No full textMolecular dynamics results on water confined in a silica pore in the low hydration regime are presented. Strong layering effects are found due to the hydrophilic character of the substrate. The local properties of water are studied as function of both temperature and hydration level. The interaction of the thin films of water with the silica atoms induces a strong distortion of the hydrogen bond network. The residence time of the water molecules is dependent on the distance from the surface. Its behavior shows a transition from a Brownian to a non-Brownian regime approaching the substrate in agreement with results found in studies of water at contact with globular proteins.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Brain stimulation in obsessive-compulsive disorder (OCD): A systematic review
No full textBackground: Obsessive-compulsive disorder (OCD) is a highly prevalent, severe, and chronic disease. There is a need for alternative strategies for treatment-resistant OCD. Objective: This review aims to assess the effect of brain stimulation techniques in OCD. Methods: We included papers published in peer-reviewed journals dealing with brain stimulation techniques in OCD. We conducted treatment-specific searches for OCD (Technique AND ((ran-domized OR randomised) AND control* AND trial) AND (magnetic AND stimulation OR (rTMS OR dTMS)) AND (obsess* OR compuls* OR OCD)) on six databases, i.e., PubMed, Cochrane, Scopus, CINAHL, PsycINFO, and Web of Science to identify randomised controlled trials and ClinicalTrials.gov for possible additional results. Results: Different add-on stimulation techniques could be effective for severely ill OCD patients unresponsive to drugs and/or behavioural therapy. Most evidence regarded deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS), while there is less evidence regarding transcranial direct current stimulation (tDCS), electroconvulsive therapy, and vagus nerve stimulation (for these last two there are no sham-controlled studies). Low-frequency TMS may be more effective over the supplementary motor area or the orbitofrontal cortex. DBS showed best results when targeting the crossroad between the nucleus accumbens and the ventral capsule or the subthalamic nucleus. Cathodal tDCS may be better than anodal in treating OCD. Limitations. We had to include methodologically inconsistent underpowered studies. Conclusion: Different brain stimulation techniques are promising as an add-on treatment of refractory OCD, although studies frequently reported inconsistent results. TMS, DBS, and tDCS could possibly find some use with adequate testing, but their standard methodology still needs to be established
Parasomnias
No full textParasomnias are defined undesirable physical events or experiences that occur during entry into sleep, within sleep or during arousals from sleep. Parasomnias occur more frequently in children than in adults. All parasomnias can be diagnosed based on subjective
reports from the patient, parent or caregiver, except for REM sleep behavior disorder where diagnosis requires polysomnographic investigation. This chapter also addresses the main clinical features and most recent treatments of parasomnias
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Sleep disturbance in anxiety disorders
No full textAnxiety disorders are the most frequent psychiatric disorder with a lifetime prevalence of 29% in the general population. Anxiety-related hyperarousal can often lead to persistent circadian rhythm and sleep disturbances. Patients affected by anxiety disorders, including post-traumatic stress disorder, panic disorder, obsessive compulsive disorder, generalized anxiety disorder, and phobias, often manifest sleep disturbances or complaints. Sleep disorders/disturbances are commonly associated with anxiety: impaired sleep can damage
neurocognitive performance and increase daily anxiety. Restoring a correct circadian rhythm is essential and basic. The study of multiple relationships between sleep disturbances and anxiety symptoms is of considerable importance in medical practice
