Following the PRISMA guidelines, articles from 2019 to 2024 were gathered from Scopus, Web of Science, and PubMed, and a random-effects meta-analysis was performed, along with subgroup analyses and pathway enrichment analyses.

Consequences of Early Maternal Deprivation on Neuroinflammation and Mitochondrial Dynamics in the Central Nervous System of Male and Female Rats.

Early life stress (ELS) is associated with an increased risk for neuropsychiatric disorders, and both neuroinflammation and mitochondrial dysfunction seem to be central to mental health. Herein, using an animal model of ELS, a single episode of maternal deprivation (MD, 24 h on pnd 9) extensively documented to elicit behavioural anomalies in male and female Wistar rats, we investigated its consequences in terms of neuroinflammation and mitochondrial dynamics in the prefrontal cortex (PFC) and the hippocampal formation (HCF). MD differentially affected the brain content of cytokines: MD induced a transient increase in pro-inflammatory cytokines (IL-1β and IL-6) in the PFC, as well as in the levels of the anti-inflammatory cytokine IL-10 in the HCF.

A Rapid Methodology to Obtain Silver Selenide thin Films with Highly Enhanced Thermoelectric Performance.

Metal chalcogenides have been extensively studied for thermoelectric applications. Among other metal chalcogenides, silver selenide (AgSe) is considered one of the most promising n-type semiconducting materials for thermoelectric applications due to its low band gap value, Seebeck coefficient, and superior power factor (PF) rendered at room temperature. However, one of the main drawbacks of using AgSe as a thermoelectric material on a large scale is the time-consuming physical methods to obtain them, and the need for high vacuum synthesis conditions as well as high-cost.
