Alzheimer’s disease (AD) is the most common type of dementia. AD involves major pathologies such as amyloid-β (Aβ) plaques and neurofibrillary tangles in brain. During progression AD, microglia can be polarized from anti-inflammatory M2 to pro-inflammatory M1 phenotype. The activation triggering receptor expressed on myeloid cells 2 (TREM2) may result phenotype switching M2, which finally attenuated Aβ deposition memory loss AD. Low-dose ionizing radiation (LDIR) known ameliorate pathology...

Patients with classified into two subgroups according gene signature: SOX2-high SOX2-low. The was further validated independent cohorts. Moreover, response radiotherapy assessed patients relationship between vitro experiment. subgroup had a better prognosis than SOX2-low all three patient Results multivariate regression...
This study demonstrates rapid carbon nanotube (CNT) synthesis using a 150 kHz induction heating system, enabling precise temperature and pressure control in thermal chemical vapor deposition processes. CNT growth optimization at temperatures between 887 955 °C pressures from 1 to 700 Torr reveals that an optimized (887 °C) (100 Torr) yield enhanced field emission performance. The provided faster rates more consistent distribution across the substrate, significantly enhancing efficiency....
Abstract Casticin (CTC), one of the major components Vitex rotundifolia L., has been reported to exert significant beneficial pharmacological activities and can function as an antiprolactin, anticancer, anti‐inflammatory, neuroprotective, analgesic, immunomodulatory agent. This study aimed at investigating whether proapoptotic effects CTC may be mediated through abrogation signal transducers activators transcription‐3 (STAT3) signaling pathway in a variety human tumor cells. We found that...

Gastric adenocarcinoma (GAC) is a lethal disease characterized by genomic and clinical heterogeneity. By integrating 8 previously established signatures for GAC subtypes, we identified 6 clinically molecularly distinct consensus subtypes (CGSs). CGS1 have the poorest prognosis, very high stem cell characteristics, IGF1 expression, but low alterations. CGS2 enriched with canonical epithelial gene expression. CGS3 CGS4 copy number alterations immune reactivity. However, differ in that has HER2...

Thirty were prospectively enrolled randomly assigned receive or general supportive skin care. Radiation pain examined at daily intervals from start radiotherapy until 4 weeks after its completion. The primary endpoint this incidence dermatitis. secondary endpoints time onset dermatitis, duration maximum score. Results. reduced grade ≥2...
The probability of recurrence cancer after adjuvant or definitive radiotherapy in patients with human papillomavirus-negative (HPV(-)) head and neck squamous cell carcinoma (HNSCC) varies for each patient.

We identified genes closely correlated validated them Cancer Genome Atlas (TCGA) cohort. RSS...
Predictive factors for radiation pneumonitis (RP) after helical tomotherapy (HT) may differ from those linac-based radiotherapy. In this study, we identified predictive RP in patients with lung cancer treated HT.We retrospectively analyzed clinical, treatment-related and dosimetric 31 HT. was graded according to Common Terminology Criteria Adverse Events version 4.0 grade ≥2 defined as a event. We used Kaplan-Meier methods compute the actuarial incidence of RP. For univariate multivariate...
This study was performed to evaluate the efficacy and safety of clove-based herbal mouthwash in ameliorating radiation-induced oral mucositis patients with head neck cancer.Fourteen were prospectively enrolled this randomized either an experimental group or a control group. The swished their mouths during radiotherapy (RT), while clear water. primary end point incidence mucositis. secondary points time onset mucositis, duration supplemental nutrition through feeding tube, maximum pain score,...
Background: We propose a novel prognostic biomarker-based strategy for increasing the efficacy of radiotherapy (RT) in head and neck squamous cell carcinoma (HNSCC). Materials Methods: identified genes associated with superoxide dismutase 2 (SOD2) nuclear factor erythroid-2-related (NRF2) from gene-expression data The Cancer Genome Atlas (TCGA) by calculating Pearson correlation. Patients were divided into two groups using hierarchical clustering. Colony-formation assay was performed to...
Quality of life (QoL) has become a major concern as the survival time breast cancer increases. We investigated changes in QoL through comprehensive categorical analysis, for first three years after treatment including radiotherapy. A total 1156 patients were enrolled from 17 institutions. All survivors grouped according to surveillance period 9–15 months (first year), 21–27 (second and 33–39 (third year) end The 5-dimensional questionnaire by EuroQol group (EQ-5D) EORTC Life Questionnaire;...
Compared to conventional radiotherapy (RT), intensity-modulated (IMRT) significantly reduces the rate of treatment-induced late toxicities in head and neck cancer. However, a clear survival benefit IMRT over RT has not yet been shown. This study is among first comparative compare rates between helical tomotherapy cancer.From January 2008 November 2011, 37 patients received 30 for management We retrospectively compared treated with tomotherapy, analyzed prognostic factors survival.The 1-...
We describe patterns of tumor regression based on follow-up duration after radiotherapy (RT) or chemo-RT in patients with head and neck squamous cell carcinoma.Thirty-one carcinoma were included this study received definitive RT chemo-RT. The pattern primary treatment was evaluated every 1 to 2 months. Predictive factors for the length time full also analyzed.Among all patients, 27 showed tumor, 24 >50% regression, 15 total regression. gradually regressed during course follow-up. median 5.2...
Abstract Background Various cancer stem cell (CSC) biomarkers and the genes encoding them in head neck squamous carcinoma (HNSCC) have been identified evaluated. However, validity of these factors prognosis HNSCC has questioned remains unclear. In this study, we examined clinical significance CSC biomarker HNSCC, using five publicly available cohorts. Methods To predict patients with developed validated expression signatures whose mRNA levels correlated at least one four ( CD44 , MET ALDH1A1...
Although numerous studies have used systemic approaches to identify prognostic predictors in oral squamous cell carcinoma (OSCC), the effectiveness of these has not been assessed clinically. Further, mechanism underlying malignant behaviors OSCC is poorly characterized. This study aimed develop and verify accurate for patients assess associated biology. We identified an OSCC-recurrence-related gene signature (ORGS) using a Cox regression analysis. Functional enrichment analysis was enriched...

We report the enhancement of carbon nanotube (CNT) field emitters by growing them directly on stripe-patterned alloy substrates. For a gate voltage 1300 V, CNT grown full and substrates achieved respective emission currents 0.22 2.32 mA, corresponding to tenfold performance enhancement. Performance is attributed reduced screening effect (as result spacing between strips) during damage-free patterning process. To verify ability generate X-rays, we designed assembled an electron gun through...
