Preliminary Evidence of a Horizontal Transfer of Paramutation Phenomenon at the Gene in Maize ( L.).

Paramutation, a specific epigenetic phenomenon first identified in by Alexander Brink in the 1950s, has since been observed in different plant and animal species. What sets paramutation apart from other gene silencing processes is its ability for one silenced allele (referred to as paramutagenic) to silence another allele (paramutable) in trans. The resultant silenced allele (paramutated) remains stable across generations, even after separating from the paramutagenic allele, and acquires paramutagenic properties itself.

The Association between Post-Traumatic Stress Disorder, 5HTTLPR, and the Role of Ethnicity: A Meta-Analysis.

Background/objectives: The current meta-analysis looks at the effect of ethnicity on the connection between 5-HTTLPR SNPs and PTSD patients in all published genetic association studies.

Techniques: In accordance with PRISMA principles, the literature was searched in PubMed, Scopus, and ScienceDirect. A consistent method was followed by two reviewers who independently chose publications for inclusion and extracted data.

Assessing mother's childbirth-related posttraumatic stress disorder during the first year postpartum: a systematic review.

Background And Aim: PTSD after childbirth is a significant but often under-recognised mental health problem. This systematic review aims to examine the measures used to assess childbirth-related PTSD (CB-PTSD) and posttraumatic stress symptoms (CB-PTSS) in mothers in the first year postpartum and to evaluate their psychometric properties.

Methods: Following PRISMA guidelines, a comprehensive search of multiple databases and grey literature sources was conducted.

Postpartum-Specific Anxiety and Maternal-Infant Bonding: A Predictive Validity Study amongst Italian Women.

The role of anxiety is unknown in relation to postpartum bonding, unlike the well-known detrimental effect that postpartum depression has on the relationship between a mother and child. This study investigates how anxiety affects mother-infant bonding after childbirth, comparing the Italian version of the Postpartum Specific Anxiety Scale (PSAS-IT) with generalized measures of anxiety. Examining 324 non-randomly-selected participants responding to various scales, including the Edinburgh postnatal depression scale (EPDS), generalized anxiety disorder (GAD), postpartum-specific anxiety scale (PSAS-IT), postpartum bonding questionnaire (PBQ), and baby care questionnaire (BCQ-2), initial results suggest a link between certain postpartum anxiety symptoms and attachment problems.
