Hydrogen storage properties of mutiwalled carbon nanotubes (MWCNTs) with Ni nanoparticles were investigated. The metal dispersed on MWCNTs surfaces using an incipient wetness impregnation procedure. catalysts have been known to effectively dissociate hydrogen molecules in gas phase, providing atomic possible form chemical bonding the MWCNTs. desorption spectra 6 wt % showed that approximately 2.8 was released range 340-520 K. In Kissinger's plot evaluate nature interaction between and...

Programmed death-ligand 1 (PD-L1) expression is regarded as a predictive marker for anti-PD-1/PD-L1 therapy. The purpose of study was to explore the changes in PD-L1 head and neck squamous cell carcinoma (HNSCC) during treatment. Paired HNSCC tissues prior after cisplatin-based treatment were evaluated determine protein by immunohistochemistry. Among 35 patient samples, status changed 37.1% (13/35) samples. 13 patients whose baseline negative, increased 9 cases (69.2%) remained negative 4...
Lamin B1, a crucial component of the nuclear lamina, plays pivotal role in chromatin organization and transcriptional regulation eukaryotic cells. While recent studies have highlighted connection between B1 RNA splicing regulation, precise molecular mechanisms remain elusive. In this study, we demonstrate that depletion leads to global reduction factor expression, as evidenced by analysis multiple RNA-seq datasets. Motif suggests members ETS transcription family likely bind promoter regions...
The purpose of this study is to investigate the effect comprehensive oral care program on health status and symptoms in head neck cancer (HNC) patients undergoing radiotherapy.This was a quasi-experimental using non-equivalent control group non-synchronized design. All participants including experimental were asked for European Organization Research Treatment Cancer Quality Life Questionnaire H&N35 (EORTC QLQ-H&N35) given an education 4 times at baseline, immediate postradiotherapy, 3 months...
Metastasis to the stomach from renal cell carcinoma (RCC) is extremely rare. Usually, gastric metastasis seems be a late event in patients with RCC and accompanied by disseminated tumor spread other organs. Solitary synchronous small, localized has rarely been reported. We report case of 79-year-old man presenting single erosive lesion pT1 RCC. The patient underwent radical nephrectomy endoscopic resection for metastatic cancer. resected specimen showed an ill-defined tumor, approximately...
We investigated the effect of chemoradiotherapy with PP2 and temozolomide (TMZ) on malignant glioma cells using clonogenic assays in vivo brain tumor model. The radiosensitivity U251 T98G was assays. expression E-cadherin, matrix metalloproteinases 2 (MMP2), Ephrin type-A receptor (EphA2), vascular endothelial growth factor (VEGF) measured by Western blotting an accumulation γH2AX foci 6 hours after radiotherapy treatment. migration, invasion, vasculogenic mimicry formation (VMF) evaluated....
Early tumor detection is crucial for the prevention of colon cancer. Near-infrared fluorescence (NIRF) imaging using a target-activatable probe may permit earlier disease detection. Matrix metalloproteinases (MMPs) participate in tumorigenesis and growth. The aim this study was to determine whether NIRF an MMP-activatable can detect tumors at early stages.WE UTILIZED TWO MURINE COLON CANCER MODELS: sporadic cancer model induced by azoxymethane (AOM), colitis-associated combination AOM...
We investigated the tumor suppressor activity and regulatory mechanism of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) in gastric cancer; 15-PGDH expression was lost 70.1% malignant human tissues, but preserved normal metaplastic gastritis. KATO III SNU-719 cells were transfected with pcDNA3.1-empty vector or an encoding wild-type 15-PGDH. In TUNEL assays apoptotic cell numbers increased KATO-PGDH-WT compared control. found that EGFR ERK1/2 inhibitors clearly cells. Our findings...
Polyethylene glycol (PEG)-based gut lavage solutions are safe and effective, but require the intake of large volumes fluid. The use 2 L PEG plus 45 mL sodium phosphate (PEG2 NaP) was compared with 4 (PEG4) for bowel cleansing before colonoscopy.Patients were randomized to PEG2 NaP group or PEG4 between January 1, 2009 March 31, 2010. One hundred thirty patients included in group, 141 group.The qualities preparation, based on Ottawa scale not significantly different groups (4.8±2.25 vs....
This study was performed to investigate the influence of object shape and distance from center image on volumetric accuracy cone-beam computed tomography (CBCT) scans, according different parameters tube voltage current.Four geometric objects (cylinder, cube, pyramid, hexagon) with predefined dimensions were fabricated. The consisted Teflon-perfluoroalkoxy embedded in a hydrocolloid matrix (Dupli-Coe-Loid TM; GC America Inc., Alsip, IL, USA), encased an acrylic resin cylinder assembly. An...

Cerebral air embolism is an extremely rare complication of endoscopic procedure and often life threatening. We present two cases cerebral infarction due to embolization caused by intervention. The first case occurred during esophageal balloon dilatation for the treatment a stricture anastomosis site in 59-year-old man second papillary 69-year-old who had distal common bile duct stones. After procedure, cardiopulmonary instability altered mental status were observed both patients, was...
Abstract Salts play a crucial role in maintaining human health by regulating fluid levels and supporting various physiological processes. However, conventional seawater-derived salts are associated with microplastic pollution pose potential risks. Jeju lava seawater (JLS), sourced exclusively from Island, has emerged as unique alternative, free of microplastics enriched essential minerals such magnesium, calcium, zinc, iron. In this study, we investigated the effects JLS on osteoarthritis...
Purpose This study aimed to compare the inverse planning simulated annealing (IPSA) stochastic algorithm with hybrid and optimization (HIPO) for interstitial tongue high-dose-rate (HDR) brachytherapy. Methods Twenty patients who received radiotherapy cancer using HDR brachytherapy were retrospectively selected this study. Oncentra Brachy v. 4.3 was used IPSA HIPO planning. Four eight fixed catheter configurations determined according target shape. During process, predetermined constrain...
Cytokeratin-type intermediate filaments are a polygenic family of insoluble proteins that vary according to cell origin and have been proposed as potentially useful markers differentiation in epithelial malignancies. Because gastrointestinal malignancies resemble each other their expression many soluble antigens, we compared the cytokeratins seven colonic, three gastric, six pancreatic, one duodenal carcinoma lines, colon villous adenoma line. Cytokeratins were characterized by one-...
