Background: Childhood maltreatment (CM) exerts long-lasting psychological and biological alterations in affected individuals and might also affect the endocannabinoid (eCB) system which modulates inflammation and the endocrine stress response. Here, we investigated the eCB system of women with and without CM and their infants using hair samples representing eCB levels accumulated during the last trimester of pregnancy and 10-12 months postpartum.

Methods: CM exposure was assessed with the .

The quality of maternal caregiving is an important factor in the healthy development of a child. One consequence of prolonged insensitive and atypical maternal interaction behavior (e.g.

The attachment representation (AR) of individuals affects emotional and cognitive information processes and is considered an important modulating factor of neuroendocrine stress responses. The neuropeptide oxytocin is studied as one biomolecular component underpinning this modulation. A validated procedure used in attachment-related research is the Adult Attachment Projective Picture System (AAP).

Background: Stress-related alterations in the regulation of several endocrine systems, including the hypothalamus-pituitary-adrenal (HPA) and -gonadal (HPG) axes and the endocannabinoid system are proposed to be involved in the etiology of major depressive disorder (MDD). Therefore, this study examines whether altered concentrations of glucocorticoids, testosterone, endocannabinoids, and related -acylethanolamines accumulated in hair are present in MDD.

Methods: Female participants (range: 19-59,  = 30.

Introduction: As an especially burdensome experience, childhood maltreatment (CM) can have lifelong consequences on the mental health and wellbeing of an individual well into adulthood. We have previously reported that CM constitutes a central risk factor not only for the development of mental problems, but also for facing additional psychosocial risks, endangering healthy development of mother and offspring throughout life (e.g.

The neuropeptide oxytocin (OXT) and its receptor (OXTR) modulate interpersonal relationships, particularly mother-child interactions. DNA methylation (DNAm) changes of the OXTR gene were observed in individuals who experienced Childhood Maltreatment (CM). A modulatory role of single nucleotide polymorphisms (SNP) within OXTR in association with CM on the regulation of OXTR was also postulated.

DNA methylation of the elongation of very long chain fatty acids protein 2 () was suggested as a biomarker of biological aging, while childhood maltreatment (CM) has been associated with accelerated biological aging. We investigated the association of age and CM experiences with methylation in peripheral blood mononuclear cells (PBMC). Furthermore, we investigated methylation in the umbilical cord blood mononuclear cells (UBMC) of newborns of mothers with and without CM.

Article Synopsis
  • Researchers looked at how major depressive disorder (MDD) affects mitochondrial energy production and oxidative stress in women with mild to moderate depression.
  • They found no significant differences in mitochondrial function or oxidative stress markers between 20 women with MDD and 24 non-depressed women.
  • The study suggests that changes in mitochondrial energy and oxidative stress may be more related to severe or chronic depression, rather than mild cases.

Childhood maltreatment (CM) comprises experiences of abuse and neglect during childhood. CM causes psychological as well as biological alterations in affected individuals. In humans, it is hardly explored whether these CM consequences can be transmitted directly on a biological level to the next generation.

Yersinia enterocolitica is a common cause of food-borne gastrointestinal disease leading to self-limiting diarrhea and mesenteric lymphadenitis. Occasionally, focal abscess formation in the livers and spleens of certain predisposed patients (those with iron overload states such as hemochromatosis) is observed. In the mouse oral infection model, yersiniae produce a similar disease involving the replication of yersiniae in the small intestine, the invasion of Peyer's patches, and dissemination to the liver and spleen.

Yersinia enterocolitica synthesizes N-acyl-L-homoserine lactone (AHL) signal molecules via the LuxR-LuxI homologues YenR-YenI. In this study we checked two prototypes of mouse-virulent Y. enterocolitica serotype O8 strains WA-314 and 8081 for AHL production in vitro and in vivo (mouse infection model).
