Background: Plasma and urine levels of the potent vasodilator Ang-(1-7) are elevated in mid and late pregnancy and are correlated with elevated placental angiogenesis, fetal blood flow, and rapid fetal growth. We hypothesized that Ang-(1-7), its receptor (Mas1) and the enzymes involved in Ang-(1-7) production (ACE2 and Membrane metallo-endopeptidase; MME) are down regulated in response to glucocorticoid administration contributing to IUGR. Methods: Pregnant female Sprague-Dawley rats were injected with dexamethasone (DEX; 0.4 mg/kg/day) starting from 14 day gestation (dg) till sacrifice at 19 or 21 dg while control groups were injected with saline (n = 6/group). The gene and protein expression of ACE2, MME, Ang-(1-7) and Mas1 receptor in the placental labyrinth (LZ) and basal zones (BZ) were studied.

This cross-sectional study provides a general profile of mothers of children with ASDs in Kuwait and examines their use of social support resources and coping strategies (using the Brief COPE questionnaire). The majority of mothers reported decreased ability to perform social duties (62.4%) and take care of themselves (50.5%). Overall, 57.7% of mothers reported a decreased ability to enjoy life; this difference was more pronounced among non-Kuwaiti mothers compared to Kuwaiti mothers (p value = 0.03), and in mothers with a bachelor's degree or higher (p value = 0.011). There was a significant association between the mothers' ability to enjoy life and receiving support from the family (p value = 0.021) and support groups (p value = 0.003). "Religion", "Acceptance", and "Positive Reframing" were the 3 most common coping strategies.

The Editors-in-Chiefare issuing an Expression of Concern for this article [1]. After publication concerns were raised with respect to the specificity and validity of the placental Ang-(1-7) levels assessed by Western blotting and reported in Fig. 4 because Ang-(1-7), which is less than 1 kDa, was detected as a 34 kDa protein. All authors disagree with this Expression of Concern.
