Aim Concurrent chemoradiotherapy (CRT) is the standard of care for locally advanced, unresectable non-small cell lung carcinoma (NSCLC). The aim of this study was to assess the prognostic value of maximum standardized uptake values (SUVmax) in patients with unresectable stage III NSCLC treated with concurrent CRT. Method 18F-FDG PET-CT scans were obtained before and after treatment in patients with unresectable stage III NSCLC treated with concurrent CRT. To determine the prognostic value of SUVmax of the primary tumor (PT), univariate and multivariate Cox regression model were carried out...

BACKGROUND: Few data exist regarding the clinical outcome of patients with Ewing sarcoma (EWS) treated with pencil beam scanning proton therapy (PT). We report the outcome of children, adolescents and young adults (AYA) treated with PT at the Paul Scherrer Institute. MATERIALS: Thirty-eight patients (median age, 9.9 years) received a median dose of 54.9 Gy(RBE) (where RBE is relative biologic effectiveness). Size of the tumor ranged from 1.7 to 24 cm. Most common primary site was axial/pelvic (n = 27; 71%)...

BACKGROUND: Currently, stratification of patients with bladder cancer (BC) mainly relies on histopathologic and clinical staging. Furthermore, inflammation plays an important role in the pathogenesis of BC. With the preoperative platelet-to-leukocyte ratio (PLR), we introduce a novel prognostic marker based on routine hematologic values in patients undergoing radical cystectomy (RC). PATIENTS AND METHODS: In our cohort of 665 patients undergoing RC (2004-2015) for urothelial carcinoma of the bladder (UCB), we analyzed a variety of preoperative hematologic parameters...

CeO2 nanoparticles were incorporated into the cavity of zeolitic imidazolate framework-8 (ZIF-8) materials followed by high temperature pyrolysis to generate CeO2@N doped carbon materials. The introduction of the CeO2 nanoparticles greatly enhanced the oxygen reduction reaction (ORR) catalytic activity of the ZIF-8 derived carbon materials owing to existence of amounts of Ce3+ in CeO2 and oxygen vacancies with high chemisorbed oxygen content and the well-maintained skeleton of the original ZIF-8 with uniform mesoporous structure...

Despite a series of attempts during the last decades, the prognosis of esophageal squamous cell carcinoma (ESCC) remains poor. Different responses of individual tumors encouraged us to look for valuable prognostic markers. As a key regulator controlling the anabolic ketogenic pathway, 3-hydroxy-3-methylglutaryl-CoA synthase 2 (HMGCS2) has been reported to play a crucial role in colorectal cancer and prostate cancer. However, its importance to ESCC has not been verified. Therefore, a large cohort retrospective study was planned, to investigate the relationship between HMGCS2 expression and ESCC prognosis...

While it has been demonstrated that receipt of neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) improves survival compared to RC alone, the driving factor for this benefit may be from patients with ypT0 status at surgery. Meanwhile, the implications of having residual urothelial carcinoma of the bladder (rUCB) at RC after NAC are less clear. We therefore evaluated whether survival differed between patients with rUCB at RC after NAC and stage-matched controls who underwent RC alone. Patients who underwent NAC + RC (n = 180) were matched to controls who underwent RC alone (n=324) on the basis of pT and pN stage, margin status, and year of RC...

Background: Coagulation and nutrition play important roles in cancer progression. We aim to investigate the impact of the fibrinogen/albumin ratio(FAR) in esophageal squamous cell carcinoma (ESCC) patients. Methods: We retrospectively analyzed 1135 patients with radical esophagectomy for ESCC from January 2008 to December 2010 in our center. X-tile software was used to determine the optimal cutoff levels for these biomarkers. Results: The optimal cutoff value was 0.08 for the FAR by the X-tile software. The FAR was statistically significantly associated with age(p=0...

Intake of water contaminated with lead (Pb(2+)) and mercury (Hg(2+)) ions leads to various toxic effects and health issues. In this context, an amperometric urease inhibition-based biosensor was developed to detect Pb(2+) and Hg(2+) ions in water matrix. The modified Pt/CeO2/urease electrode was fabricated by immobilizing CeO2 nanoparticles and urease using a semi-permeable adsorption layer of nafion. With urea as a substrate, urease catalytic activity was examined through cyclic voltammetry. Further, maximum amperometric inhibitive response of the modified Pt/CeO2/urease electrode was observed in the presence of Pb(2+) and Hg(2+) ions due to the urease inhibition at specific potentials of -0...

Aromatase inhibitors have been widely used for the endocrine treatment of estrogen-dependent breast cancer in postmenopausal patients. However, clinicopathological studies of aromatase have been limited due to unsatisfactory specificity and/or restricted availability of anti-aromatase antibodies. Here, we have generated a polyclonal antiserum with high affinity and specificity for human aromatase using a monoclonal antibody tagged immunoaffinity chromatography on an industrial production scale. Our preliminary immunohistochemical analysis of 221 invasive breast cancer cases indicated that 87...

Our previous study showed that miR-1826 was a newly identified oncogenic non-coding RNA in colorectal cancer. But the potential relationship between miR-1826 and tumor metastasis has not been fully elucidated. The purpose of this study was to evaluate the clinical significance of circulating miR-1826 and its possible associations with circulating tumor cells in colorectal cancer. Our results first found that serum miR-1826 was significantly upregulated in colorectal cancer patients, compared with that in healthy volunteers ( p = 0...

We report a large spin Hall angle observed in vanadium films sputter-grown at room temperature, which have small grain size and consist of a mixture of body centered tetragonal (bct) and body centered cubic (bcc) structures. The spin Hall angle is as large as θ V  = -0.071 ± 0.003, comparable to that of platinum, θ Pt  = 0.076 ± 0.007, and is much larger than that of bcc V film grown at 400 °C, θ V_bcc  = -0.012 ± 0.002. Similar to β-tantalum and β-tungsten, the sputter-grown V films also have a high resistivity of more than 200 μΩ∙cm...

Immunohistochemistry of a transcription factor, GATA3, has been widely used as a promising urothelial marker in diagnostic surgical pathology practice. However, the expression status of GATA3 in upper urinary tract urothelial carcinomas (UUTUCs) and its prognostic significance have not been fully investigated. We immunohistochemically stained for GATA3 in 99 UUTUC samples and paired non-neoplastic urothelial tissues. GATA3 was positive in 51 [51.5%; 32 (32.3%) weak, 11 (11.1%) moderate, 8 (8.1%) strong] of 99 UUTUCs, which was significantly lower than in benign urothelium [79 (96...

Cystic fibrosis (CF) liver disease (CFLD), a leading cause of death in CF, is mostly described in pediatric populations. Adult-onset CFLD lacks sufficient characterization and diagnostic tools. A cohort of CF patients without CFLD during childhood were followed for up to 38 years with serologic testing, imaging, and noninvasive fibrosis markers. Historical CFLD diagnostic criteria were compared with newly proposed CFLD criteria. Thirty-six CF patients were followed for a median of 24.5 years (interquartile range 15...

The incidence of renal cell carcinoma is increasing all over the world. The molecular mechanisms for tumorigenesis, progression and prognosis are still unknown. The erythropoietin-producing hepatoma amplified sequence (Eph) receptors have been reported to be expressed aberrantly in many types of human cancers and in particular EphA5 may play a role in certain human cancers. In this study, a set of clear cell renal cell carcinoma (ccRCC) tissues were subjected to immunohistochemistry. The relationship between EphA5 protein expression and clinicopathological parameters was statistically analysed...
