A poorly understood finding with potentially wide-ranging implications is that subliminal stimulation with "Mommy and I are one" affects behavior. In this study (n= 62), "Mommy and I are one" lowered implicit mood (p= 0.0015) in comparison with a neutral stimulus ("People are walking"). The effect was most pronounced in shame-prone participants with less positive memories of their mother, and low self-mother complementarity (interaction p= 0.0044). Effects of a potentially shame-inducing stimulus ("I am completely isolated") were not significant (ps > 0.11). The results concerning less positive memories of mother replicate previous findings. We suggest that activation of unconscious associative networks explains the data. Though more research is needed, the cognitive content of these networks may involve representations of self-with-mother; for some, the affective content could involve shame.

Characterization of language abilities and semantic networks in very preterm children at school-age.

It has been widely assessed that very preterm children (<32 weeks gestational age) present language and memory impairments compared with full-term children. However, differences in their underlying semantic memory structure have not been studied yet. Nevertheless, the way concepts are learned and organized across development relates to children's capacities in retrieving and using information later.

Postpartum depression (PPD) adversely affects the growth and development of the offspring, increasing the risk of various internalizing behaviorsduring adolescence. Studies have shown that corticosterone (CORT)-induced PPD affects neurogenesis in the offspring, which is closely related to the onset of depression. However, the underlying mechanisms of these changes in the offspring of PPD mothers remain unexplored.

Introduction: Common variable immunodeficiency is a diagnosis of exclusion in immunodeficient patients with increased susceptibility to infections, hypogammaglobulinemia, deficient response to vaccination, or low percentages of switched memory B cells. In low- and middle-income countries, the elucidation and study of molecular defects in these patients may take decades.
Objective: To elucidate the genetic defect conferring impaired immunity in a patient diagnosed with common variable immunodeficiency.
Maternal education and prenatal smoking associations with adolescent executive function are substantially confounded by genetics.

Twin studies have suggested extremely high estimates of heritability for adolescent executive function, with no substantial contributions from shared environment. However, developmental psychology research has found significant correlations between executive function outcomes and elements of the environment that would be shared in twins. It is unclear whether these seemingly contradictory findings are best explained by genetic confounding in developmental studies or limitations in twin studies, which can potentially underestimate shared environment.

The opioid crisis continues to escalate, disproportionately affecting women of reproductive age. Traditionally the first line of treatment for pregnant women with opioid use disorder is the mu-opioid receptor agonist methadone. However, in recent years, the use of buprenorphine as a replacement therapy has increased as it has fewer side-effects and longer duration of action.
