Room-temperature ferromagnetic semiconductor Fe-doped β-GaO thin films with high saturation magnetization and low coercivity.

Emergent ferromagnetism in β-GaO with an ultra-wide bandwidth and high electrical breakdown strength offers exciting opportunities for fabricating robust spintronic devices. One pertinent obstacle in the material has been the low saturation magnetization, which precludes its practical application in magnetic devices. In this work, large-scale Fe-doped β-GaO diluted magnetic semiconductor (DMS) films are synthesized using a polymer-assisted deposition method, and the effect of Fe doping on their structural and magnetic properties is investigated.

The Efficacy and Safety Assessment of Sequential Liposuction Modified Double Ring Areola Incision in Moderate and Severe Breast Ptosis Correction.

Background: A total of 42 cases of moderate and severe breast ptosis were treated with sequential liposuction modified double ring areola incision surgery (experimental group), and 45 cases were treated with traditional double ring areola incision alone surgery (control group).

Methods: They were followed up for 6 months after the operation. The scar formation and breast ptosis repair were observed, and postoperative complications and patient satisfaction were monitored.

miR-203 suppression in gastric carcinoma promotes Slug-mediated cancer metastasis.

MicroRNAs (miRNAs) play critical roles in tumorigenesis and cancer metastasis. Recently, miR-203 was reported as a tumor suppressor microRNA silenced in different malignancies including hepatocellular carcinoma, prostate cancer, oral cancer, breast cancer, and hematopoietic malignancy, whereas its role in the carcinogenesis of gastric carcinoma (GC) has not been evaluated. Here, we analyzed the levels of miR-203 and Slug in the GC specimen and studied their correlation.

Suppression of vascular endothelial growth factor abrogates the immunosuppressive capability of murine gastric cancer cells and elicits antitumor immunity.

The mechanisms underlying immune evasion by gastric cancer have not been well described due to a lack of gastric tumor models in immunocompetent mice. In the current study, we found that supernatants from MFC cells, a murine gastric cancer line, inhibited the lipopolysaccharide (LPS) induced maturation and cross-presentation of bone-marrow-derived dendritic cells (BMDCs). Moreover, MFC tumor-derived factors markedly altered the cytokine profiles of BMDCs, leading to a trend of increased levels of interleukin 4 (IL4), IL6, IL23 and transforming growth factor β, as well as decreased levels of tumor necrosis factor α.
