Article Abstract
Gestational diabetes mellitus (GDM) may increase the risk of suboptimal neurocognitive development in infants. Maternal supply of omega-3 and -6 long chain polyunsaturated fatty acids (LCPUFAs), including eicosapentaeonic acid, docosahexaenoic acid and arachidonic acid, are critical for offspring brain development. To study the effects of GDM on offspring brain fatty acid composition, C57BL/6J mice were exposed to short-term high-fat diet feeding and low-dose streptozotocin treatments before pregnancy. Maternal blood glucose levels positively correlated to offspring brain omega 6:omega 3 ratio at postnatal day 2 and day 21, which appeared to be driven specifically by higher omega-6 LCPUFA levels. GDM may be associated with impaired brain fatty acid profile in offspring, and this may underpin altered neurodevelopmental outcomes after GDM pregnancies. These findings support further investigation into the therapeutic potential of postnatal dietary interventions targeting fatty acid status in infants born after GDM.

BackgroundWomen have a higher risk of dementia than men. Reproductive factors may be implicated.ObjectiveDetermine the association between reproductive factors (earlier menarche, later menopause, longer reproductive lifespan (RLS), post-menopausal hormone replacement therapy [pmHRT] use, and serum estradiol/estrone) and neurocognitive and neuroimaging markers of brain aging and incident dementia in cognitively healthy women.

Pollution can have lasting effects beyond the exposure period, potentially impacting multiple generations. Polybrominated diphenyl ether (PBDE) flame retardants are widespread, including in oceans, yet their multigenerational impacts remain poorly understood. We investigated whether BDE-99, a ubiquitous PBDE, induces neurobehavioral and molecular effects across generations in the fish .

A family history of depression is a well-documented risk factor for offspring psychopathology. However, the genetic mechanisms underlying the intergenerational transmission of depression remain unclear. We used genetic, family history, and diagnostic data from 11,875 9-10 year-old children from the Adolescent Brain Cognitive Development study.

Current therapeutics for hypoxic/ischemic brain damage can benefit from insights resulting from the study of hypoxia/anoxia resistant organisms. Hypoxia resistance, however, is not a common feature in mammalian models. Being naturally exposed to hypoxic/anoxic conditions, the sea hare could become a very useful model for the study of hypoxia resistance.

Within the broader topic of women's intuition, the focus of this work is mother-offspring intuition-the enigmatic connection between a mother and her offspring, wherein distress or imminent harm is instantly sensed, even when thousands of miles apart. Instant nonlocal communication irrespective of distance, is known as entanglement in quantum physics, and has been repeatedly verified since the 1970's. Building upon this discovery, a new concept--is postulated to create a two-way micro to macroscale bond of tacit connection between a mother and a fetus, initiated at conception.
