Cartilaginous metaplasia is rare in primary central nervous system (CNS) neoplasms and has not been described in the histone 3 (H3) gene (H3) with a substitution of lysine to methionine (H3 K27M mutant) diffuse midline glioma before. Here, we report a case of H3 K27M mutant diffuse midline glioma with cartilaginous metaplasia in a 56-year-old woman. Magnetic resonance imaging (MRI) revealed a ring-enhanced lesion located in the medulla oblongata and extended superiorly into the fourth ventricle. The tumor was macroscopically completely resected. Histologically, the tumor was composed of a gliomatous component and a well-differentiated cartilaginous component. Microvascular proliferation and necrosis were noted. According to immunohistochemical staining, glial cells were diffusely and strongly positive for glial fibrillary acidic protein (GFAP), oligodendrocyte lineage transcription factor 2 (Olig2), H3 K27M, and S-100 protein but negative for H3K27me3. The chondrocytes also were positive for GFAP and S-100 protein. The H3 K27M mutation was confirmed by sequencing in both the gliomatous and cartilaginous components, suggesting a common origin from the same progenitor cells. Based on these findings, the tumor was diagnosed as a diffuse midline glioma with H3 K27M mutation with widespread cartilaginous metaplasia, corresponding to WHO grade IV. This is an extremely rare H3 K27M mutant diffuse midline glioma with cartilaginous metaplasia, and reporting this unusual case adds to the understanding of this tumor type.Zingiber officinale Rosc. (Zingiberacae), commonly known as ginger, is a perennial and herbaceous plant with long cultivation history. Ginger rhizome is one of the most popular food spices with unique pungent flavor and is prescribed as a well-known traditional Chinese herbal medicine. To date, over 160 constituents, including volatile oil, gingerol analogues, diarylheptanoids, phenylalkanoids, sulfonates, steroids, and monoterpenoid glycosides compounds, have been isolated and identified from ginger. Decitabine Increasing evidence has revealed that ginger possesses a broad range of biological activities, especially gastrointestinal-protective, anti-cancer, and obesity-preventive effects. In addition, gingerol analogues such as 6-gingerol and 6-shogaol can be rapidly eliminated in the serum and detected as glucuronide and sulfate conjugates. Structural variation would be useful to improve the metabolic characteristics and bioactivities of lead compounds derived from ginger. Furthermore, some clinical trials have indicated that ginger can be consumed for attenuating nausea and vomiting during early pregnancy; however, there is not sufficient data available to rule out its potential toxicity, which should be monitored especially over longer periods. This review provides an up-to-date understanding of the scientific evidence on the development of ginger and its active compounds as health beneficial agents in future clinical trials.

Previously, we used ultrasound (US)-mediated cisplatin (CDDP)-loaded microbubbles (CDDP-MBs) to increase intratumoral CDDP level while decreasing systemic cytotoxicity. Statins have shown antitumorigenic properties. Our study investigated the effects of atorvastatin with CDDP-MBs and US on head neck cancer.

Cell viability analysis with CDDP-MBs and atorvastatin combined with US in FaDu cell line were tested. Cell proliferation and glutathione level were also evaluated.

Both CDDP and atorvastatin reduced cell's viability. Coadministration of CDDP and atorvastatin resulted in synergistic inhibitory effect. After US sonication, cell viability with atorvastatin and CDDP was significantly reduced for CDDP combined with MBs (65.98% to 49.13%) and for CDDP-MBs (86.17% to 50.15%). CDDP-MBs combined with atorvastatin and US inhibited the proliferation of cells 19.61% for CDDP-MBs + atorvastatin + US, 36.28% for CDDP + atorvastatin, and 71.73% for atorvastatin alone. Also, CDDP-MBs + atorvastatin + US induced apoptosis by decreasing cellular level of glutathione.

Atorvastatin combined with MB-conjugated CDDP exerts synergistic inhibitory effect on head neck cancer.

In the single-crystalline form, MoS2 shows superior electronic properties. It is also an exceptionally useful nanomaterial in its polycrystalline form with applications in catalysis, energy storage, water treatment, and gas sensing. Here, the scalable fabrication of longitudinal MoS2 nanostructures, i.e., nanoribbons, and their oxide hybrids with tunable dimensions in a rational and well-reproducible fashion, is reported. The nanoribbons, obtained at different reaction stages, that is, MoO3 , MoS2 /MoO2 hybrid, and MoS2 , are fully characterized. The growth method presented herein has a high yield and is particularly robust. The MoS2 nanoribbons can readily be removed from its substrate and dispersed in solution. It is shown that functionalized MoS2 nanoribbons can be manipulated in solution and assembled in controlled patterns and directly on microelectrodes with UV-click-chemistry. Owing to the high chemical purity and polycrystalline nature, the MoS2 nanostructures demonstrate rapid optoelectronic response to wavelengths from 450 to 750 nm, and successfully remove mercury contaminants from water. The scalable fabrication and manipulation followed by light-directed assembly of MoS2 nanoribbons, and their unique properties, will be inspiring for device fabrication and applications of the transition metal dichalcogenides.

The purpose of this study was to evaluate the long-term mortality and cause of death in patients with tracheostomy.

Data from the Korean National Health Insurance Service-Health Screening Cohort were collected from 2002 to 2013. A total of 2394 tracheostomy participants and 9536 control participants were included in this study. The crude and adjusted hazard ratios (HRs) for tracheostomy-associated mortality were analyzed. Subgroup analysis according to age and cause of death was analyzed.

The tracheostomy group showed a significantly higher rate of death (69.1%) than the nontracheostomy group (13.3%). The adjusted HR for mortality was 13.5 in the tracheostomy group. The most common cause of death after tracheostomy was a circulatory disease, followed by neoplasm, respiratory disease, and trauma.

Patients with tracheostomy had a significantly increased long-term mortality rate compared with patients with nontracheostomy. The circulatory disease was the most common cause of death following tracheostomy.
