Summary: This study found that pregnant mice with reduced ASIC2a expression may not be able to mount an inflammatory response following acute seizure exposure. Due to the decrease in ASIC2a, the concentration of pro-inflammatory cytokines and chemokines in the hippocampal cytosolic fraction of pregnant mice was reduced.

Summary: Accumulating evidence suggests that maternal nicotine exposure affects hippocampal neurogenesis and cognitive behaviors in offspring. In this study, developmental nicotine exposure was found to delay physical and neurobehavioral development, increase anxiety-like behavior, and alter gene expression related to inflammation, neurotransmitters, and synapses in the hippocampus. Furthermore, nicotine exposure skewed microglial polarity towards M2 phenotype, potentially contributing to abnormal cognitive and behavioral performance in offspring.

Summary: In this study, resting-state functional magnetic resonance imaging (rs-fMRI) was used to detect early brain injury in acute kidney injury (AKI) rats and investigate the impact of microglia on the neuropathological mechanism of AKI. The results showed that AKI led to a decreased amplitude of low-frequency fluctuations (ALFF) in the hippocampus, especially at 48 h and 72 h. AKI activated the aggregation of microglia into neurons at 24 h, with a peak at 48 h, accompanied by the release of proinflammatory cytokines. The study demonstrated that microglia aggregation and inflammatory factor upregulation are significant mechanisms of AKI-induced neuronal apoptosis.

Summary: Despite advances in hippocampus-sparing radiation therapy, radiation-induced injury to the neural stem cell compartment may impact neurocognitive functions. Low doses of ionizing radiation induced inflammatory responses in the hippocampus, with activated microglia and reactive astrocytes, suggesting a shift from neurogenesis to gliogenesis. These findings emphasize the importance of limiting radiation dose to preserve neurocognitive functions, particularly in the juvenile hippocampus.

Summary: Microglia, originating from mesoderm, play key roles in the development, homeostasis, and innate immunity of the central nervous system (CNS). Their diverse morphological characteristics are closely related to their wide range of functions. However, our knowledge of the morphophysiological attributes and interactions with neurons of microglia is limited. Exploring the correlation between microglial shape and function is a current challenge and opportunity.

Summary: This study investigated the effects of acute paraquat exposure on the phenotypic polarization of hippocampal microglia and its mechanism. The results showed that acute paraquat exposure can induce hippocampal inflammatory damage by activating the JAK2/STAT3 pathway and promoting M1-type polarization of microglia, leading to the release of pro-inflammatory factors.

Summary: Pleistocene glaciations had a significant impact on the distribution and genetic makeup of species in temperate ecosystems. Through the analysis of ibex genomes, it was discovered that the Himalayan ibex in the Pamir Mountains evolved independently from its main range around 0.1 million years ago according to the Pleistocene species pump concept. The demographic trajectories of the Himalayan ibex indicated two historic bottlenecks and an intermediate population expansion coinciding with the Mid-Pleistocene Transitions. This study provides evidence that the Himalayan ibex is an evolutionary distinct species from the Siberian ibex and highlights the need for taxonomic revision and conservation planning.

Summary: This study focused on blue sheep in the Western trans Himalayas of India and found suitable habitat for blue sheep within an area of approximately 18,775 km(2). The genetic analysis identified two populations of blue sheep, Ladakh and Lahaul-Spiti, with high genetic divergence. The study also highlighted the impact of landscape heterogeneity and unsuitable habitats on population divergence and functional connectivity. Although the blue sheep population has been demographically stable in the past, there has been a slight decline in recent decades.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
