Associations Between Parents' Cognitions About Child Anxiety and Emotion Dysregulation in Clinically Anxious Children: The Unique Contribution of Fathers.

This study examined the influence of parental cognition, including attitudes, beliefs, and understanding of anxiety, on emotion dysregulation in children with anxiety disorder. A total of 47 clinically anxious children (6-17 years old) and their parents were involved in the current study. The mothers and fathers separately completed a self-reported questionnaire assessing their attitudes, beliefs, and understanding of their children's anxiety, while the children completed a self-report questionnaire assessing emotion dysregulation.

Corrosion inhibition in acidic environments: key interfacial insights with photoelectron spectroscopy.

In many engineering scenarios, surface-active organic species are added to acidic solutions to inhibit the corrosion of metallic components. Given suitable selection, such corrosion inhibitors are highly effective, preventing significant degradation even in highly aggressive environments. Nevertheless, there are still considerable gaps in fundamental knowledge of corrosion inhibitor functionality, severely restricting rational development.

Nonuniqueness of hydrodynamic dispersion revealed using fast 4D synchrotron x-ray imaging.

Experimental and field studies reported a significant discrepancy between the cleanup and contamination time scales, while its cause is not yet addressed. Using high-resolution fast synchrotron x-ray computed tomography, we characterized the solute transport in a fully saturated sand packing for both contamination and cleanup processes at similar hydrodynamic conditions. The discrepancy in the time scales has been demonstrated by the nonuniqueness of hydrodynamic dispersion coefficient versus injection rate (Péclet number).

Social anxiety disorder in children: investigating the relative contribution of automatic thoughts, repetitive negative thinking and metacognitions.

Background: Social anxiety disorder (SAD) is common in youths. However, our understanding of SAD in children is inferior to that of SAD in adolescents or adults, and it is unclear if known adult SAD maintenance mechanisms may also operate in children with SAD.

Aim: The paper sets out to investigate the specificity of positive automatic thoughts, social threat negative automatic thoughts, repetitive negative thinking, positive and negative metacognitions in predicting SAD symptoms and diagnoses in clinically anxious children.

Mothers' and children's metacognitions and the development of childhood anxiety: a longitudinal investigation of transmission.

Theory and preliminary evidence suggests that parental beliefs and cognitions may be transmitted to their offspring. Transmission of maladaptive cognitions may play a role in the development of anxiety disorders in childhood. However, few studies have investigated such transmission using longitudinal designs.

Increasing access to low-intensity interventions for childhood anxiety: A pilot study of a guided self-help program for Scandinavian parents.

Cognitive Behavior Therapy (CBT) is an effective treatment for child anxiety. However, access to treatment is limited. It has been suggested that low-intensity formats of parent-delivered CBT may improve access to treatment.

Cognitive Behavior Therapy and Metacognitive Therapy: Moderators of Treatment Outcomes for Children with Generalized Anxiety Disorder.

Although cognitive behavioral therapy (CBT) is effective for childhood anxiety disorders, approximately 40% of youth remain anxious after treatment. Metacognitive therapy (MCT-c) for children with generalized anxiety disorder (GAD) has shown promising effects. The present study aimed to examine if CBT and MCT-c show differential effects in children with primary GAD based on baseline characteristics, in a quasi-experimental design.

Does comorbidity predict poorer treatment outcome in pediatric anxiety disorders? An updated 10-year review.

The aim of the present review was to provide an updated investigation of literature from the past ten years that examined the effects of comorbid problems on treatment outcomes, and/or explored if cognitive behavioral treatments (CBT) targeting anxiety disorders also affected comorbid disorders. A search of the literature resulted in a total of 33 publications, based on 28 randomized controlled trials that met predefined inclusion criteria. An analysis of studies that examined whether comorbidity affects treatment outcome yielded mixed results for different types of comorbidities.

Attachment as a predictor of non response to CBT treatment in children with anxiety disorders.

Children's and parents' attachment patterns have been linked with the presence of pediatric anxiety disorders. The present study examined the role of attachment in predicting cognitive behavior therapy (CBT) treatment outcomes. A total of 69 children aged 7-13 years were assessed using a semi-structured interview, and treated with CBT.

Determining the Chemical Composition of Corrosion Inhibitor/Metal Interfaces with XPS: Minimizing Post Immersion Oxidation.

An approach for acquiring more reliable X-ray photoelectron spectroscopy data from corrosion inhibitor/metal interfaces is described. More specifically, the focus is on metallic substrates immersed in acidic solutions containing organic corrosion inhibitors, as these systems can be particularly sensitive to oxidation following removal from solution. To minimize the likelihood of such degradation, samples are removed from solution within a glove box purged with inert gas, either N2 or Ar.

In Situ Solid-State Reactions Monitored by X-ray Absorption Spectroscopy: Temperature-Induced Proton Transfer Leads to Chemical Shifts.

The dramatic colour and phase alteration with the solid-state, temperature-dependent reaction between squaric acid and 4,4'-bipyridine has been probed in situ with X-ray absorption spectroscopy. The electronic and chemical sensitivity to the local atomic environment through chemical shifts in the near-edge X-ray absorption fine structure (NEXAFS) revealed proton transfer from the acid to the bipyridine base through the change in nitrogen protonation state in the high-temperature form. Direct detection of proton transfer coupled with structural analysis elucidates the nature of the solid-state process, with intermolecular proton transfer occurring along an acid-base chain followed by a domino effect to the subsequent acid-base chains, leading to the rapid migration along the length of the crystal.

Parental Involvement in Cognitive Behavior Therapy for Children with Anxiety Disorders: 3-Year Follow-Up.

Parental factors have been linked to childhood anxiety, hence, parental involvement in cognitive behavioral therapy (CBT) for anxious children has been examined. However, findings do not consistently show added effects of parent-enhanced CBT, longitudinal investigations are scarce and long-term effects unclear. In the present study, 40 out of 54 families who, 3 years previously, completed one of two types of CBT treatment: with limited or active parental involvement, were assessed using semi-structured diagnostic interviews.

Toward understanding the chloroquine action at the molecular level in antimalarial therapy--X-ray absorption studies in acetic acid solution.

The local atomic structure around the central iron of the synthetic soluble analog of malarial pigment in acetic acid solution and with addition of chloroquine as found by X-ray absorption spectroscopy is reported. The special interest was drawn to the axial linkage between the central iron atom of the ferriprotoporphyrin IX (FePPIX) coordinated axially to the propionate group of the adjacent FePPIX. This kind of bonding is typical for hematin anhydride.

Understanding chloroquine action at the molecular level in antimalarial therapy: X-ray absorption studies in dimethyl sulfoxide solution.

X-ray absorption spectroscopy is used to determine the local atomic structure around the iron atom from a soluble synthetic analogue of malaria pigment (hemozoin), cf. ferrimesoporphyrin IX of mesohematin anhydride, in the absence or presence of chloroquine (CQ) in dimethyl sulfoxide (DMSO). Of particular note are the CQ-induced changes in the structure of mesohematin anhydride, which might confirm the formation of CQ-ferrimesoporphyrin IX complex.

The use and characterization of a backilluminated charge-coupled device in investigations of pulsed x-ray and radiation sources.

Examinations of bremsstrahlung and energetic electron beams from a novel laser plasma source motivate and assist characterization of a backthinned, backilluminated direct detection x-ray charge-coupled device (CCD), a topology that is uncommon in hard x-ray work. Behavior toward pseudomonochromatic ((55)Fe) and multichromatic ((241)Am) sources is briefly reviewed under optimized noise conditions. Results collectively establish the previously unknown functional depth structure.

The structure of Fe(III) ions in strongly alkaline aqueous solutions from EXAFS and Mössbauer spectroscopy.

To establish the structure of ferric ions in strongly alkaline (pH > 13) environments, aqueous NaOH solutions supersaturated with respect to Fe(III) and the solid ferric-hydroxo complex salts precipitating from them have been characterized with a variety of experimental techniques. From UV measurements, in solutions of pH > 13, only one kind of Fe(III)-hydroxo complex species was found to be present. The micro crystals obtained from such solutions were proven to be a new, so far unidentified solid phase.

A broadband laser plasma x-ray source for application in ultrafast chemical structure dynamics.

A plasma source free from characteristic emission lines is described, based on laser irradiation of a water jet in a helium atmosphere. Various key aspects of the laser interaction are presented along with practical characterization of the observed isotropic approximately 4-10 keV x-ray emissions, measurements of which indicate subpicosecond duration. Observations are consistent with a vacuum heating plasma mechanism at the helium-water interface and indicate strong potential for in-house ultrafast chemical structure dynamics application when coupled to contemporary detector developments.

Prevalence of cardiovascular risk factors in erectile dysfunction.

Objective: Thirty million men in the United States may have erectile dysfunction, and coronary artery disease (CAD) is the major cause of death in men over 55 years old. Several studies have shown a correlation between erectile dysfunction and risk factors for coronary artery disease. Hyperlipidemia plays a pivotal role in CAD, and obesity is now considered an independent risk factor for CAD.
