Article Abstract
Microglia are innate immune cells in the central nervous system (CNS) and play critical roles in proper brain development and function. During postnatal development, microglia have a highly plastic morphology and change rapidly in response to the temporal brain environment. However, their dynamics and phenotypes during this period are still not fully elucidated. Here, we systematically elucidated microglial density and morphological changes during postnatal development as well as in pathological obese conditions. Our results demonstrated a spatiotemporal distribution of microglia in different brain regions associated with gradually increased microglial complexity during postnatal development. Moreover, microglia become reactive in most brain regions of obese mice, but their morphological diversity has a region-specific manner, with an obvious alteration in the hypothalamus. Overall, our data emphasized the morphological dynamics of microglia following developing time windows and provided the basic information for future investigations.

Patterns of extreme outlier gene expression suggest an edge of chaos effect in transcriptomic networks.
Genome Biol

Department of Evolutionary Genetics, Max-Planck Institute for Evolutionary Biology, Plön, Germany.
Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

This study investigated the impact of dietary zeolite supplementation on growth, cecal microbiota and digesta viscosity, digestive enzymes, carcass traits, blood constituents, and antioxidant parameters of broilers. A completely randomized design was used with 240 one-day-old broiler chicks randomly assigned to three dietary treatments (0%, 1.5%, and 3% zeolite as a feed additive) with four replicates of 20 chicks each.

Background: Volatile anesthetics are gaining recognition for their benefits in long-term sedation of mechanically ventilated patients with bacterial pneumonia and acute respiratory distress syndrome. In addition to their sedative role, they also exhibit anti-bacterial and anti-inflammatory properties, though the mechanisms behind these effects remain only partially understood. In vitro studies examining the prolonged impact of volatile anesthetics on bacterial growth, inflammatory cytokine response, and surfactant proteins - key to maintaining lung homeostasis - are still lacking.

Background: Plant roots release root exudates to attract microbes that form root communities, which in turn promote plant health and growth. Root community assembly arises from millions of interactions between microbes and the plant, leading to robust and stable microbial networks. To manage the complexity of natural root microbiomes for research purposes, scientists have developed reductionist approaches using synthetic microbial inocula (SynComs).

Background: Anxiety symptoms during pregnancy are a frequent mental health issue for expectant mothers and fathers. Research revealed that prenatal anxiety symptoms can impact parent-child bonding and child development. This study aims to investigate the prospective relationship between prenatal anxiety symptoms and general child development and whether it is mediated by parent-child bonding.
