A Comprehensive Review of Exosomes with Therapeutic Potential in Cancer and Coeliac Disease

The aim of this review was to evaluate the therapeutic potential of exosomes, extracellular vesicles secreted by cells. They have emerged as potential therapeutic transporters for several diseases. This review provides an overview of exosomes’ therapeutic potential in cancer therapy and autoimmune conditions such as Coeliac Disease. The therapeutic effect is that the phospholipid-binding protein ANXA1 improves its anti-inflammatory properties. The review also analyzes the intricate processes of exosome production and composition ability to transport biomolecules such as proteins, microRNAs, and lipids, which promote intercellular communication and alter recipient cell behavior. Exosomes, linked to neurological disorders, cardiovascular disease, and cancer, present the means of targeted drug administration due to their innate specificity. Through genetic engineering and chemical modifications, exosomes can be tailored for specific purposes, demonstrating their versatility in targeted therapy. With ongoing research uncovering their therapeutic potential, exosomes present a promising frontier in novel medical treatments across various health conditions.

Combining acellular nerve allografts with brainderived neurotrophic factor transfected bone marrow mesenchymal stem cells restores sciatic nerve injury better than either intervention alone

In this study, we chemically extracted acellular nerve allografts from bilateral sciatic nerves, and repaired 10-mm sciatic nerve defects in rats using these grafts and brain-derived neurotrophic factor transfected bone marrow mesenchymal stem cells. Experiments were performed in three groups： the acellular nerve allograft bridging group, acellular nerve allograft ＋ bone marrow mesenchymal stem cells group, and the acellular nerve allograft ＋ brain-derived neurotrophic factor transfected bone marrow mesenchyrnal stem cells group. Results showed that at 8 weeks after bridging, sciatic functional index, triceps wet weight recovery rate, myelin thickness, and number of myelinated nerve fibers were significantly changed in the three groups. Variations were the largest in the acellular nerve allograft ＋ brain-derived neurotrophic factor transfected bone marrow mesenchymal stem cells group compared with the other two groups. Experimental findings suggest that chemically extracted acellular nerve allograft combined nerve factor and mesenchymal stem cells can promote the restoration of sciatic nerve defects. The repair effect seen is better than the single application of acellular nerve allograft or acellular nerve allograft combined mesenchymal stem cell transplantation.

A Brief Introduction to the Writing Strategy-Process Writing

Process writing has been commonly recognized by scholars as an effective writing strategy and widely applied in the teaching of writing. The stages of process writing have been elaborated in this paper through the introduction of overseas core articles in this field from a scientific perspective combined with a cognition angle. Implications have been put forward to teachers at the end of this paper.

A Brief Review on Recasts

Recast is the most frequently used error correction technique adopted by teachers in the communicative oriented classrooms. This article illustrates the reasons for its popularity, also discusses how to use recast effectively in practice.

Detecting prostate cancer and prostatic calcifications using advanced magnetic resonance imaging

Prostate cancer and prostatic calcifications have a high incidence in elderly men. We aimed to investigate the diagnostic capabilities of susceptibility-weighted imaging in detecting prostate cancer and prostatic calcifications. A total number of 156 men, including 34 with prostate cancer and 122 with benign prostate were enrolled in this study. Computed tomography, conventional magnetic resonance imaging, diffusion-weighted imaging, and susceptibility-weighted imaging were performed on all the patients. One hundred and twelve prostatic calcifications were detected in 87 patients. The sensitivities and specificities of the conventional magnetic resonance imaging, apparent diffusion coefficient, and susceptibility-filtered phase images in detecting prostate cancer and prostatic calcifications were calculated. McNemar＇s Chi-square test was used to compare the differences in sensitivities and specificities between the techniques. The results showed that the sensitivity and specificity of susceptibility-filtered phase images in detecting prostatic cancer were greater than that of conventional magnetic resonance imaging and apparent diffusion coefficient （P 〈 0.05）. In addition, the sensitivity and specificity of susceptibility-filtered phase images in detecting prostatic calcifications were comparable to that of computed tomography and greater than that of conventional magnetic resonance imaging and apparent diffusion coefficient （P 〈 0.05）. Given the high incidence of susceptibility-weighted imaging （SWl） abnormality in prostate cancer, we conclude that susceptibility-weighted imaging is more sensitive and specific than conventional magnetic resonance imaging, diffusion-weighted imaging, and computed tomography in detecting prostate cancer. Furthermore, susceptibility-weighted imaging can identify prostatic calcifications similar to computed tomography, and it is much better than conventional magnetic resonance imaging and diffusion-weighted imaging.
