OBJECTIVE To examine the association between biological stress regulation and somatic complaints in young girls prior to the onset of clear psychopathology such as somatization disorder. METHODS Salivary cortisol, heart rate variability (HRV), and negative mood were assessed in 48 12-year-old girls in response to the Trier Social Stress Test for Children (TSST-C). Parent and child report on t...

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...
