Atomoxetine suppresses radioresistance in glioblastoma via circATIC/miR-520d-5p/Notch2-Hey1 axis.

Background: Resistance acquired after radiotherapy is directly related to the failure of various cancer treatments, including GBM. Because the mechanism for overcoming radioresistance has not yet been clearly identified, the development of diagnostic and therapeutic markers to treat radioresistance is necessary. Since increased expression of stemness- and EMT-related markers are reported to be closely correlated with radioresistance, research is underway to develop new drugs targeting these factors.

Mandibular Condylar Head Regeneration Owing to Remodeling of the Costochondral Graft After Condylectomy for Odontogenic Myxoma.

Odontogenic myxoma of the mandibular condyle is a rare tumor that requires complete surgical resection because of the tendency for recurrence. The right mandibular condyle was resected to remove the myxoma. The author performed immediate condylar reconstruction using a costochondral graft (CCG), and stable temporomandibular joint (TMJ) function and occlusion were achieved.

miR-1226-5p is involved in radioresistance of colorectal cancer by activating M2 macrophages through suppressing IRF1.

Background: Although the representative treatment for colorectal cancer (CRC) is radiotherapy, cancer cells survive due to inherent radioresistance or resistance acquired after radiation treatment, accelerating tumor malignancy and causing local recurrence and metastasis. However, the detailed mechanisms of malignancy induced after radiotherapy are not well understood. To develop more effective and improved radiotherapy and diagnostic methods, it is necessary to clearly identify the mechanisms of radioresistance and discover related biomarkers.

Effects of Aging on New Bone Regeneration in a Mandibular Bone Defect in a Rat Model.

The effects of aging on the healing capacity of maxillofacial bone defects have not been studied. The aim of this study was to evaluate the effects of aging on the regeneration of round bony defects in the mandible. We created a round-shaped bony defect in the mandibular angle area in rats of different ages (2-[2 M], 10-[10 M], and 20-month-old [20 M]) and evaluated new bone regeneration in these groups.

Carbapenem non-susceptibility overcalling by BD phoenix NMIC-500 panel.

We aimed to assess the accuracy of BD Phoenix for determining carbapenem susceptibility because we observed a decline in carbapenem susceptibility rate from the biannual cumulative data, after we transitioned to the BD Phoenix form Vitek 2 system. Between October 2021 and May 2022, we collected 82 non-duplicated Enterobacterales showing non-susceptible to at least one of the three carbapenems by BD Phoenix. We performed the broth microdilution (BMD) and disk diffusion (DD) according to the CLSI guideline.

Tumor-derived miR-6794-5p enhances cancer growth by promoting M2 macrophage polarization.

Background: Solid tumors promote tumor malignancy through interaction with the tumor microenvironment, resulting in difficulties in tumor treatment. Therefore, it is necessary to understand the communication between cells in the tumor and the surrounding microenvironment. Our previous study revealed the cancer malignancy mechanism of Bcl-w overexpressed in solid tumors, but no study was conducted on its relationship with immune cells in the tumor microenvironment.

miR-765 as a promising biomarker for low-dose radiation-induced pulmonary fibrosis.

High-dose radiation (HDR) is widely used for cancer treatment, but the effectiveness of low-dose radiation (LDR) in the treatment of various diseases is controversial. Therefore, to safely utilize LDR for therapeutic purposes, further research on its numerous biological effects of LDR is required. Interest in the increased use of medical imaging devices or the effects of surrounding living environmental radiation on the human body, particularly on fibrosis, is rapidly increasing.

Long-Term Changes in Adipose Tissue in the Newly Formed Bone Induced by Recombinant Human BMP-2 In Vivo.

Recombinant human bone morphogenetic protein-2 (rhBMP-2) induces osteogenesis and adipogenesis in bone scaffolds. We evaluated rhBMP-2-induced long-term changes in adipose tissue in the newly formed bone in different scaffolds forms. Bovine bone particles and blocks were grafted along with rhBMP-2 in the subperiosteal space of a rat calvarial bone, and the formation of new bone and adipose tissue were evaluated at 6 and 16 weeks after the surgery.

Targeting miR-5088-5p attenuates radioresistance by suppressing Slug.

Radiotherapy is widely used for cancer treatment, but paradoxically, it has been reported that surviving cancer cells can acquire resistance, leading to recurrence or metastasis. Efforts to reduce radioresistance are required to increase the effectiveness of radiotherapy. miRNAs are advantageous as therapeutic agents because it can simultaneously inhibit the expression of several target mRNAs.
