The evaluation of ultrasonic vocalizations (USVs) during isolation in 6-8-day-old mouse pups can give an indication of the perception of pups' discomfort and need for caretaker presence to overcome the unpleasant condition. Time spent vocalizing changed according to opioid activation, stress exposure, and genetic profile of pups. Deficits in attachment suggest altered opioid functioning and predisposal for long-term defective social behaviors and reward processes.

Background: Necrotizing enterocolitis (NEC) is a gastrointestinal emergency in premature neonates. NEC is mediated by toll-like receptor-4 (TLR-4) and associated with lung injury. Previously, we showed that prenatal heparin-binding epidermal growth factor (HB-EGF) administration decreases the incidence of intestinal injury in a rat model of NEC.

Loss of actin cytoskeleton control can hinder integral developmental and physiological processes and can be the basis for a subset of developmental defects. SHROOM3 is an actin binding protein, best characterized as being essential for neural tube closure in vertebrates. Shroom3 expression has also been identified in the developing heart, with some associated congenital heart defects.

Mutations in the human ADAR gene encoding adenosine deaminase acting on RNA 1 (ADAR1) cause Aicardi-Goutières syndrome 6 (AGS6); a severe auto-inflammatory encephalopathy with aberrant interferon (IFN) induction. AdarΔ2-13 null mutant mouse embryos lacking ADAR1 protein die with high levels of IFN-stimulated gene (ISG) transcripts. In Adar Mavs double mutants also lacking the Mitochondrial antiviral signaling (MAVS) adaptor, the aberrant IFN induction is prevented.

Background: Germinal matrix hemorrhage (GMH) is a common complication of premature infants with lifelong neurological consequences. Inflammation-mediated blood-brain barrier (BBB) disruption has been implicated as a main mechanism of secondary brain injury after GMH. The cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a crucial role in inflammation, yet its involvement in GMH pathophysiology remains unclear.

Background: Early postnatal undernutrition, leading to impaired growth and low body weight, has been associated with enduring metabolic alterations that may persist into adulthood. We proposed that plant-based ω-3 fatty acids, as in maternal supplementation, attenuate metabolic alterations induced by postnatal dietary restriction, such as glucose disturbances and oxidative stress.
Methods: To test this, we investigated the effects of maternal supplementation with two distinct doses of Chia Oil (ChO) (2.
