Study on the Mechanism of Bone Marrow Stem Cell-Derived Exosome miR-30a/DLL4 Acting on Traumatic Brain Injury Angiogenesis.

Objective: To explore the effects of bone marrow stem cell (BMSC)-derived exosome miR-30a/DLL4 expression on angiogenesis following traumatic brain injury (TBI), which may provide a novel therapeutic strategy for postoperative TBI recovery.

Methods: A rat TBI model was established using the free-fall method, and exosomes from different sources were injected into the brain. Rats were divided into sham-operated, TBI model, TBI+inhibitor NC-Exo, TBI+miR-30a-inhibitor-Exo, TBI+OE NC-Exo, and TBI+DLL4-OE-Exo groups.

[Effects of Vegetation Restoration on the Structure and Function of the Rhizosphere Soil Bacterial Community of ].

Invasive plants can change soil microbial communities and therefore promote invasion. While vegetation restoration has been adopted in certain infested lands to curb the invasion of , changes in the composition and function of rhizosphere soil bacterial communities of the species before and after the restoration has not yet been reported. In this study, two vegetation combinations used in previous studies were selected as candidates:++ (T1) and +++ (T2).

[Effects of invasive Cenchrus spinifex on nitrogen pools in sandy grassland].

Cenchrus spinifex is an invasive plant found in large areas of northern China. In this study, we focused on analysis of the effects of C. spinifex on soil nitrogen and plant nitrogen pools in Horqin sandy grassland.

[Effects of Flaveria bidentis invasion on the diversity of functional bacteria in rhizosphere soil.].

Flaveria bidentis is an invasive plant found in large areas of northern China. This study conducted a separation and screening of the main functional bacteria in the soil of F. bidentis and investigated the change in the community structure.

iTRAQ Protein Profile Differential Analysis of Dormant and Germinated Grassbur Twin Seeds Reveals that Ribosomal Synthesis and Carbohydrate Metabolism Promote Germination Possibly Through the PI3K Pathway.

Grassbur is a destructive and invasive weed in pastures, and its burs can cause gastric damage to animals. The strong adaptability and reproductive potential of grassbur are partly due to a unique germination mechanism whereby twin seeds develop in a single bur: one seed germinates, but the other remains dormant. To investigate the molecular mechanism of seed germination in twin seeds, we used isobaric tags for relative and absolute quantitation (iTRAQ) to perform a dynamic proteomic analysis of germination and dormancy.
