In this study, based on the excitatory/inhibitory imbalance theory of autism, the time window of GABA switch, the role of K-Cl co-transporter 2 (KCC2) in adjustment GABA switch, and brain permeability to erythropoietin (EPO), the effects of postnatal -EPO and- nano- erythropoietin (NEPO) have been evaluated in the valproic acid (VPA) rat model of autism. The VPA was administered for animal modeling of autism at gestational day (GD) 12.5 (600 mg/kg). Male offsprings were injected with EPO and NEPO in a clinically proper postnatal dosing regimen on postnatal days (PND) 1-5, and autistic-like behaviors were tested at the end of the first month. Then animals were sacrificed, and neuron morphology and KCC2 expression were examined by Nissl staining and Western blot. According to our findings, high-dose NEPO improved autism-associated phenotypes. Neuroprotective effects of EPO and NEPO have been shown in the hippocampus. Postnatal NEPO treatment reversed KCC2 expression abnormalities induced by prenatal VPA. Our results might support the role of KCC2 in ASD and the excitatory/inhibitory imbalance hypothesis. We suggested Nano- erythropoietin and other KCC2 interventions as a new approach to the early treatment and prevention of autism.

The brain develops most rapidly during pregnancy and early neonatal months. While prior electrophysiological studies have shown that aperiodic brain activity undergoes changes across infancy to adulthood, the role of gestational duration in aperiodic and periodic activity remains unknown. In this study, we aimed to bridge this gap by examining the associations between gestational duration and aperiodic and periodic activity in the EEG power spectrum in both neonates and toddlers.

Background: Cardiac ischemia/reperfusion disrupts plasma membrane integrity and induces various types of programmed cell death. The ESCRT (endosomal sorting complex required for transport) proteins, particularly AAA-ATPase Vps4a (vacuolar protein sorting 4a), play an essential role in the surveillance of membrane integrity. However, the role of ESCRT proteins in the context of cardiac injury remains unclear.

Background: Epidemiological studies report associations of drinking water disinfection byproducts (DBPs) with adverse health outcomes, including birth defects. Here, we used a rat model susceptible to pregnancy loss (full-litter resorption; FLR) and eye malformations (anophthalmia, microphthalmia) to test 11 DBPs, including trihalomethanes, haloacetic acids (HAAs), and nitrogen-containing DBPs (N-DBPs).
Methods: Timed-pregnant F344 rats received gavage doses of chloroform, chlorodibromomethane, iodoform, chloroacetic acid, bromoacetic acid, dibromoacetic acid (DBA), diiodoacetic acid (DIA), trichloroacetic acid (TCA), dibromonitromethane, and iodoacetonitrile on gestation days (GD) 6-10.

Background: The use of eHealth innovations is becoming increasingly important in improving health outcomes, especially for maternal and newborn health. However, planning and executing these innovations can be challenging due to their complex nature. To provide guidance and clarity on implementation approaches, researchers need to use implementation research (IR) tools.

Cerebral palsy (CP) is the most common neuromuscular disorder in children with no effective therapeutic methods. To examine CP, a large variety of methods and animal models was developed, the most popular are the hypoxic-ischemic (HI) injury and/or LPS injection in mice. In the presented work, HI and LPS were applied on the postnatal day 9 to humanized immunodeficiency mouse pups, thereupon 3 behavioral tests were performed in 8 weeks later.
