is a kind of popular functional food to be consumed by both healthy and diabetic people. As its major constituent, polysaccharide (DOP) is mainly utilized by gut microbiota. Despite distinctive gut microbiota composition between healthy and diabetic individuals, no study compared the interplay between DOP and gut microbiota under healthy and diabetic status.

Article Synopsis
- Heat stress (HS) prompts neuroinflammation and cognitive issues in the brain, leading to a study that compared the gene expression of mouse hippocampal tissue under HS conditions versus control.
- Analysis showed that HS exposure resulted in 210 differentially expressed genes, indicating significant changes, with 72 genes upregulated and 138 downregulated.
- Notably, the study found that taurine treatment could improve cognitive functions affected by HS, suggesting potential strategies for mitigating heat-induced cognitive impairments in vulnerable groups.
Exploring In Vivo Human Brain Metabolism at 10.5 T: Initial Insights from MR Spectroscopic Imaging.

Introduction: Ultra-high-field magnetic resonance (MR) systems (7 T and 9.4 T) offer the ability to probe human brain metabolism with enhanced precision. Here, we present the preliminary findings from 3D MR spectroscopic imaging (MRSI) of the human brain conducted with the world's first 10.

Chemical signaling can play a crucial role in predator-prey dynamics. Here, we present evidence that ink from the common cuttlefish (Sepia officinalis) targets olfactory receptor proteins in shark, potentially acting as a predator deterrence. We apply in silico 3D docking analysis to investigate the binding affinity of various odorant molecules to shark olfactory receptors of two shark species: cloudy catshark (Scyliorhinus torazame) and white shark (Carcharodon carcharias).

Purpose: Eyelid infiltrative basal cell carcinoma (iBCC) is the most common malignant tumor affecting the ocular adnexa, but studies on metabolic changes within its microenvironment and heterogeneity at the tumor invasive area are limited. This study aims to analyze metabolic differences among iBCC cell types using single-cell and spatial metabolomics analysis and to examine metabolic environment at the tumor invasive area.
Methods: Single-cell transcriptomic data of human basal cell carcinoma (BCC) were clustered and visualized using Uniform Manifold Approximation and Projection.
