Mastoparan M extracted from alleviates neuronal death in global cerebral ischemia-reperfusion rat model.

Objectives: Global cerebral ischemia (GCI), a consequence of cardiac arrest (CA), can significantly damage the neurons located in the vulnerable hippocampus CA1 areas. Clinically, neurological injury after CA contributes to death in most patients. Mastoparan-M extracted from (Smith) can be used to treat major neurological disorders.

Molecular signatures of soil-derived dissolved organic matter constrained by mineral weathering.

Dissolved organic matter (DOM) in soils drives biogeochemical cycling and soil functions in different directions depending on its molecular signature. Notably, there is a distinct paucity of information concerning how the molecular signatures of soil DOM vary with different degrees of weathering across wide geographic scales. Herein, we resolved the DOM molecular signatures from 22 diverse Chinese reference soils and linked them with soil organic matter and weathering-related mineralogical properties.
