Exosomes combined with biosynthesized cellulose conduits improve peripheral nerve regeneration.

Peripheral nerve injury is one of the more common forms of peripheral nerve disorders, and the most severe type of peripheral nerve injury is a defect with a gap. Biosynthetic cellulose membrane (BCM) is a commonly used material for repair and ligation of nerve defects with gaps. Meanwhile, exosomes from mesenchymal stem cells can promote cell growth and proliferation.

Construction of Exosomes that Overexpress CD47 and Evaluation of Their Immune Escape.

Our general purpose was to provide a theoretical and practical foundation for the use of exosomes (EXOs) that have high levels of CD47 as stable and efficient drug carriers. Thus, we prepared EXOs from adipose tissue-derived mesenchymal stromal cells (ADMSCs) that had high levels of CD47 (EXOs) and control EXOs (without CD47), and then compared their immune escape and their resistance to phagocytosis . Nanoflow cytometry was used to determine the CD47 level in these EXOs, and the amount of EXOs that remained in rat plasma at 3 h after intraperitoneal injection.

Investigating the effect of coal particle size on spontaneous combustion and oxidation characteristics of coal.

As a key parameter, the particle size of residual coal contributes greatly to its oxidation characteristics, so it is a significant and far-reaching topic to explore the role of different particle sizes in coal spontaneous combustion disaster. In this work, temperature-programmed system (TPS) was applied to analyze the oxygen consumption rate and CO and CH production rules of six groups of coal samples with different particle sizes in the process of oxidation heating. The critical temperature (CT) and xerochasy temperature (XT) of different coal samples were obtained, and the coal oxidation process was divided into three stages (S1, slow oxidation stage; S2, fast oxidation stage; and S3, combustion stage).

Involvement of abscisic acid-responsive element-binding factors in cassava (Manihot esculenta) dehydration stress response.

Cassava (Manihot esculenta) is a major staple food, animal feed and energy crop in the tropics and subtropics. It is one of the most drought-tolerant crops, however, the mechanisms of cassava drought tolerance remain unclear. Abscisic acid (ABA)-responsive element (ABRE)-binding factors (ABFs) are transcription factors that regulate expression of target genes involved in plant tolerance to drought, high salinity, and osmotic stress by binding ABRE cis-elements in the promoter regions of these genes.

Taxonomy and Broad-Spectrum Antifungal Activity of sp. SCA3-4 Isolated From Rhizosphere Soil of .

Actinobacteria are important producers of bioactive compounds. Extreme ecosystems cause evolution of novel secondary metabolic pathways of Actinobacteria and increase the possible discovery of new biological functions of bioactive compounds. Here, we isolated 65 Actinobacteria from rhizosphere soil samples of .

Deciphering microbial diversity associated with Fusarium wilt-diseased and disease-free banana rhizosphere soil.

Background: Fusarium wilt of banana (Musa spp.) caused by the fungal pathogen Fusarium oxysporum f. sp.

Bioinformatic identification and expression analysis of banana microRNAs and their targets.

MicroRNAs (miRNAs) represent a class of endogenous non-coding small RNAs that play important roles in multiple biological processes by degrading targeted mRNAs or repressing mRNA translation. Thousands of miRNAs have been identified in many plant species, whereas only a limited number of miRNAs have been predicted in M. acuminata (A genome) and M.

The MaASR gene as a crucial component in multiple drought stress response pathways in Arabidopsis.

Abscisic acid (ABA)-, stress-, and ripening-induced (ASR) proteins are involved in abiotic stress responses. However, the exact molecular mechanism underlying their function remains unclear. In this study, we report that MaASR expression was induced by drought stress and MaASR overexpression in Arabidopsis strongly enhanced drought stress tolerance.

Evaluation of different methods of protein extraction and identification of differentially expressed proteins upon ethylene-induced early-ripening in banana peels.

Background: Banana peels (Musa spp.) are a good example of a plant tissue where protein extraction is challenging due to the abundance of interfering metabolites. Sample preparation is a critical step in proteomic research and is critical for good results.
