In this article we present two studies about the relations between peer relationships and somatic complaints in children in Den Bosch, the Netherlands. In the first study (n=711), when the children were average 10 years old, we focused on social status as rated by classmates (popular, neglected, controversial, rejected, and average), self-reported social anxiety and somatic complaints. The seco...
Somatic mutation plays a key role in transforming normal cells into cancerous cells. The analysis of cancer progression therefore requires the study of how point mutations and chromosomal mutations accumulate in cellular lineages. The spread of somatic mutations depends on the mutation rate, the number of cell divisions in the history of a cellular lineage, and the nature of competition between...
BACKGROUND Schizophrenia often co-occurs with chronic medical illnesses. Beside comorbid somatic illness, somatic symptoms appear as a result of side effects of antipsychotics during treatment of psychotic disorders, which may lead to certain diagnostic problems in deciding regarding the origin of such symptoms (somatic illness vs. side effects). The aim of this article is to review literature ...
Somatic hypermutation (SHM) is restricted to VDJ regions and their adjacent flanks in immunoglobulin (Ig) genes, whereas constant regions are spared. Mutations occur after about 100 nucleotides downstream of the promoter and extend to 1-2 kb. We have asked why the very 5' and most of the 3' region of Ig genes are unmutated. Does the activation-induced cytosine deaminase (AID) that initiates SHM...
BACKGROUND Self-efficacy can be affected by mastery experiences and somatic sensations. A novel exercise experience and associated sensations may impact self-efficacy and subsequent behaviors. We investigated the effect of a single exercise session on self-efficacy for sedentary endometrial cancer survivors compared with sedentary women of a similar age, but with no cancer history. METHODS Tw...
Frequent somatic complaints are not only a problem in themselves but also related to other difficulties. So far, no conclusive findings have been reported about the prevalence of and factors underlying these complaints in children and adolescents who are deaf or hard of hearing (DHH). Such information would be valuable for prevention and intervention. Therefore, the aim of this study was to exa...
Somatic embryogenesis is an asexual form of plant propagation in nature that mimics many of the events of sexual reproduction. Also, this process may be reproduced artificially by the manipulation of tissues and cells in vitro. Some of the most important factors for a successful plant regeneration are the culture medium and environmental incubation conditions. In vitro somatic embryogenesis is ...
The aim of the study was to determine the ageand gender-specific prevalence, at symptom level and cluster level, of somatic symptoms in a sample of 1512 participants (52.7% females) aged 10 to 25 years old. Somatic complaints were measured with the Psychosomatic Symptoms Scale (PSS), a 35-item scale that inquires about 35 somatic symptoms and sensations in the last 3 months. PSS shows acceptabl...
This study aimed to investigate the effects of certain nutrient medium types enhanced with plant-growth regulators on direct inductionof somatic embryogenesis in vegetative strains produced and propagated from a tissue culture Digitalis purpurea. The results showthat MS was superior other tested media-B5, LS, 5C01—in terms days required initiate somaticembryogenesis induction rate. In contrast,...
Anxiety sensitivity (AS) is the fear of anxiety-related sensations based on beliefs about their harmful consequences. Despite its status as the most popular measure of AS, the anxiety sensitivity index is too abbreviated to adequately measure the somatic, cognitive, and social facets of the construct. The Anxiety Sensitivity Index - Revised (ASI-R) is a revised and expanded version of the ASI t...
