[Investigation of general toxic effects of Relatox in comparison with Dysport].

Objective: To evaluate the toxic effects of the agent Relatox on mature outbred rats and mice in an acute experiment in comparison with the registered analogue Dysport.

Material And Methods: Based on the aim of experiment, the acute toxic effects of Relatox and Dysport were assessed on two animal species: rats and mice at intraperitoneal and intramuscular administration at dose levels that made it possible to calculate the toxicological parameter values (initially 10-150 U/kg with subsequent usage of additional doses 20 U/kg to 300 U/kg depending on the agent and route of administration). The LD values and other acute toxic parameters were calculated using probit analysis.

Effect of the consumption of brazzein and monellin, two recombinant sweet-tasting proteins, on rat gut microbiota.

Sweet-tasting proteins (SPs) are proteins of plant origin initially isolated from tropical fruits. They are thousands of times sweeter than sucrose and most artificial sweeteners. SPs are a class of proteins capable of causing a sweet taste sensation in humans when interacting with the T1R2/T1R3 receptor.

One year follow-up of participants in a randomised controlled trial of a CBT-based group therapy programme for adolescents diagnosed with ADHD.

Background: Adolescents with ADHD often struggle on many areas of their lives and have a high risk of adverse outcomes and negative life trajectories. Multimodal treatment including psychosocial interventions is recommended but evidence regarding effect of such interventions is still limited.

Materials And Methods: This study was a follow-up study of adolescents participating in a randomised controlled trial (RCT) of a group intervention based on cognitive behavioural therapy (CBT).

Sweet-Tasting Natural Proteins Brazzein and Monellin: Safe Sugar Substitutes for the Food Industry.

This article presents the results of a comprehensive toxicity assessment of brazzein and monellin, yeast-produced recombinant sweet-tasting proteins. Excessive sugar consumption is one of the leading dietary and nutritional problems in the world, resulting in health complications such as obesity, high blood pressure, and cardiovascular disease. Although artificial small-molecule sweeteners widely replace sugar in food, their safety and long-term health effects remain debatable.

Prevalence of chronic and multisite pain in adolescents and young adults with ADHD: a comparative study between clinical and general population samples (the HUNT study).

Attention-deficit/hyperactivity disorder (ADHD) and chronic pain are prevalent and associated. We examined the prevalence and distribution of chronic pain in adolescents and young adults with ADHD using 9-years longitudinal data (from T1:2009-2011 to T3:2018-2019) with three time points from a clinical health survey compared to two age-matched reference population-based samples. Mixed-effect logistic regression and binary linear regression were used to estimate the probability for chronic and multisite pain at each time point and to compare the prevalence of chronic pain with the reference populations.

[Formula: see text] Executive function measured by BRIEF in adolescents diagnosed and treated for ADHD: problem profiles and agreement between informants.

Executive functional deficits (EFDs) play an important role in functional impairment in adolescents with attention deficit/hyperactivity disorder (ADHD). More knowledge of executive function (EF) profiles and informant discrepancies will guide clinicians and provide tailored treatment advice. The objectives of this study were to use teacher, parent, and self-reported EF ratings to describe (a) problem profiles and (b) the correlation and agreement between informants.

Executive functions mediate the association between ADHD symptoms and anxiety in a clinical adolescent population.

Objective: Attention-deficit/hyperactivity disorder (ADHD) is associated with a high prevalence of anxiety disorders in children and adolescents. The reasons for this association are poorly understood. Preliminary findings with young adults have suggested that executive functions and functional impairment may mediate the relationship between symptoms of ADHD and mixed anxiety and depressive symptoms.

Cognitive behavioural group therapy as addition to psychoeducation and pharmacological treatment for adolescents with ADHD symptoms and related impairments: a randomised controlled trial.

Background: Cognitive behavioural therapy (CBT) is recommended for attention-deficit/hyperactivity-disorder (ADHD) in adolescents. However, all CBTs are not created equal, and the guidelines do not specify which CBT interventions are the most effective for this patient group. This study examines the efficacy of a group CBT without parent involvement as follow-up treatment compared to no additional CBT in adolescents with persistent and impairing ADHD symptoms after a short psychoeducational intervention and medical treatment.

Effects of individual differences, society, and culture on youth-rated problems and strengths in 38 societies.

Background: Clinicians increasingly serve youths from societal/cultural backgrounds different from their own. This raises questions about how to interpret what such youths report. Rescorla et al.

Cognitive behavioural group therapy for adolescents with ADHD: a study of satisfaction and feasibility.

Background: Adolescents with ADHD are at increased risk of adverse outcomes and a negative life trajectory into adulthood. Evidence regarding treatment specifically tailored for the needs of this age group are still limited. High dropout rates, discontinuation of medication and treatment resistance are common issues in this population, and the patient perspective on new treatment options is therefore important.

Psychometric properties of the Weiss Functional Impairment Rating Scale parent and self-reports in a Norwegian clinical sample of adolescents treated for ADHD.

Objective: To analyze the psychometric properties of the Norwegian version of the Weiss Functional Impairment Rating Scale parent and self-reports (WFIRS-P and WFIRS-S) in adolescents with ADHD.

Methods: 102 clinically referred patients, of which 86% were enrolled in an ongoing RCT program (Clinical trials NCT02937142), were diagnosed with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders version IV (DSM-IV). The conceptual framework of the WFIRS-P and the WFIRS-S was evaluated using confirmatory factor analysis (CFA), reliability was estimated using Cronbach's alpha, convergent and divergent validity was assessed using correlations with the Children's Global Assessment Scale (C-GAS) and the ADHD Rating Scale-IV (ADHD-RS-IV).

Cognitive-behavioural group therapy for adolescents with ADHD: study protocol for a randomised controlled trial.

Introduction: Persistence of attention deficit hyperactivity disorder (ADHD) into adolescence is a significant burden to patients. Clinical guidelines recommend non-pharmacological therapies, but the evidence to support this recommendation is sparse. This study aims to evaluate the effect of a 12-week group cognitive-behavioural therapy (CBT) programme for adolescents with ADHD aged 14-18 years, who still have impairing symptoms after treatment with medication.

Preclinical Study of Biofunctional Polymer-Coated Upconversion Nanoparticles.

Upconversion nanoparticles (UCNPs) are new-generation photoluminescent nanomaterials gaining considerable recognition in the life sciences due to their unique optical properties that allow high-contrast imaging in cells and tissues. Upconversion nanoparticle applications in optical diagnosis, bioassays, therapeutics, photodynamic therapy, drug delivery, and light-controlled release of drugs are promising, demanding a comprehensive systematic study of their pharmacological properties. We report on production of biofunctional UCNP-based nanocomplexes suitable for optical microscopy and imaging of HER2-positive cells and tumors, as well as on the comprehensive evaluation of their pharmacokinetics, pharmacodynamics, and toxicological properties using cells and laboratory animals.

What Predicts a Good Adolescent to Adult Transition in ADHD? The Role of Self-Reported Resilience.

Objective: ADHD is a disorder associated with impairment and comorbid psychiatric problems in young adulthood; therefore, factors that may imply a more favorable outcome among adolescents with ADHD are of interest.

Method: This study used a longitudinal design to assess whether adolescent personal resilience characteristics during adolescence protected against psychosocial impairment, depression, and anxiety 3 years later. Self-reported protective factors were used as baseline measures in the assessment of 190 clinically referred adolescents with ADHD.

Improved quality of life among adolescents with attention-deficit/hyperactivity disorder is mediated by protective factors: a cross sectional survey.

Background: The aim of this study was to assess the role of protective factors as mediators and/or moderators of the relationship between coexisting emotional and conduct problems and quality of life (QoL) among adolescents with attention-deficit/hyperactivity disorder (ADHD).

Methods: The sample consisted of 194 adolescents with ADHD. Participants completed measures of individual competencies, family cohesion and social support, and QoL.

The Impact of Coexisting Emotional and Conduct Problems on Family Functioning and Quality of Life Among Adolescents With ADHD.

Objective: The aim of this study was to assess the impact of self-reported emotional and conduct problems on family functioning and quality of life (QoL) among adolescents with ADHD.

Method: The ADHD group (N = 194) was divided into the following groups: without additional emotional or conduct problems, with emotional problems, with conduct problems, and with both problem types. The cross-sectional study included parent and adolescent reports.

Sixteen-year comparisons of parent-reported emotional and behaviour problems and competencies in Norwegian children aged 7-9 years.

Background: Studies about changes in the prevalence of emotional and behaviour problems across time are lacking, especially among younger children.

Aim: To determine if the level of parent-reported emotional and behaviour problems and competencies in young Norwegian school children had changed across a 16-year time interval.

Methods: We compared parent reports obtained by the Child Behavior Checklist in two samples of children aged 7-9 years from the general population assessed in 1991 and 2007.

Cross-informant agreement between parent-reported and adolescent self-reported problems in 25 societies.

We used population sample data from 25 societies to answer the following questions: (a) How consistently across societies do adolescents report more problems than their parents report about them? (b) Do levels of parent-adolescent agreement vary among societies for different kinds of problems? (c) How well do parents and adolescents in different societies agree on problem item ratings? (d) How much do parent-adolescent dyads within each society vary in agreement on item ratings? (e) How well do parent-adolescent dyads within each society agree on the adolescent's deviance status? We used five methods to test cross-informant agreement for ratings obtained from 27,861 adolescents ages 11 to 18 and their parents. Youth Self-Report (YSR) mean scores were significantly higher than Child Behavior Checklist (CBCL) mean scores for all problem scales in almost all societies, but the magnitude of the YSR-CBCL discrepancy varied across societies. Cross-informant correlations for problem scale scores varied more across societies than across types of problems.

Familial adenomatous polyposis: mental health, psychosocial functioning and reactions to genetic risk in adolescents.

Familial adenomatous polyposis (FAP) in a parent requires diagnostic follow-up and treatment from adolescence in possible gene carriers in order to prevent cancer development. A nationwide sample (n = 22) of adolescent FAP offspring including 85% of eligible individuals aged 11-20 years and their parents were interviewed with regard to adolescent mental health, psychosocial functioning, knowledge about FAP and genetic risk, and experiences with testing and surgery. Thirty-six percent of the FAP offspring fulfilled criteria for a psychiatric diagnosis.

Mental health and psychosocial functioning in adolescents with esophageal atresia.

Purpose: We examined mental health and psychosocial functioning in adolescents with esophageal atresia (EA) and searched for predictors of impaired outcome.

Methods: The study group comprised 21 adolescents with EA and 1 or both parents. A comparison group comprised 36 adolescents from the general population.

The generalizability of the Youth Self-Report syndrome structure in 23 societies.

As a basis for theories of psychopathology, clinical psychology and related disciplines need sound taxonomies that are generalizable across diverse populations. To test the generalizability of a statistically derived 8-syndrome taxonomic model for youth psychopathology, confirmatory factor analyses (CFAs) were performed on the Youth Self-Report (T. M.

[Enzyme immunoassay of (24R)-brassinosteroids].

Brassinosteroids are a new group of phytohormones that are widely distributed in plants and play an important role in the processes of plant growth and development. Physiological concentrations of brassinosteroids in plants are extremely low, and their analysis in organs and tissues is very difficult. This study is devoted to the chemical aspects of elaboration and to bioanalytical parameters of an immunoenzymatic system for quantitative determination of the phytohormones 24-epicastasterone and 24-epibrassinolide.

Testing the 8-syndrome structure of the child behavior checklist in 30 societies.

There is a growing need for multicultural collaboration in child mental health services, training, and research. To facilitate such collaboration, this study tested the 8-syndrome structure of the Child Behavior Checklist (CBCL) in 30 societies. Parents' CBCL ratings of 58,051 6- to 18-year-olds were subjected to confirmatory factor analyses, which were conducted separately for each society.

Epidemiological comparisons of problems and positive qualities reported by adolescents in 24 countries.

In this study, the authors compared ratings of behavioral and emotional problems and positive qualities on the Youth Self-Report (T. M. Achenbach & L.
