Article Synopsis
  • - Researchers identified specific stress-responsive neurons in the middle lateral hypothalamus (mLH) and medial lateral habenula (LHbM) of mice that play a key role in developing depression-like behaviors due to chronic stress.
  • - These neurons act as "starter cells" that transmit stress information and their connections become stronger when subjected to prolonged stress.
  • - Disabling these neuronal connections can prevent depression-like behaviors, while activating them can trigger such behaviors even without stress, highlighting their crucial role in the LH-LHb circuit related to depression.

Sex heterogeneity has been frequently reported in autism spectrum disorders (ASD) and has been linked to static differences in brain function. However, given the complexity of ASD and diagnosis-by-sex interactions, dynamic characteristics of brain activity and functional connectivity may provide important information for distinguishing ASD phenotypes between females and males. The aim of this study was to explore sex heterogeneity of functional networks in the ASD brain from a dynamic perspective.

The bioreduction of toxic chromium(VI) to sparingly soluble chromium(III) represents an environmentally friendly and cost-effective method for remediating Cr contamination. Usually, this bioreduction process is slow and requires the addition of quinone compounds as electron shuttles to enhance the reaction rate. However, the dissolved quinone compounds are susceptible to loss with water flow, thereby limiting their effectiveness.

Article Synopsis
  • Stress is a significant contributor to depression, affecting specific brain areas, especially the lateral habenula (LHb), which processes negative information during stress.
  • The LHb consists of medial (LHbM) and lateral (LHbL) regions that process aversive signals differently and send feedback to other brain areas, but their precise functioning in depression progression is still unclear.
  • Recent findings highlight how stress-induced changes in the LHb can lead to increased neural activity, linking chronic stress to the onset of depression and opening avenues for targeted treatments and early intervention strategies.
