Effect of sodium borohydride and hydrogen peroxide pretreatments on soda pulping of sugar maple (Acer saccharum)
2021
For recovering value-added wood-based organic material prior to delignification, sodium borohydride (NaBH4) and hydrogen peroxide (H2O2) pretreatments under alkaline conditions were performed before soda pulping of sugar maple (Acer saccharum) chips with sodium hydroxide (NaOH). In this investigation, it was determined whether the pulp yield could be increased by partly stabilizing the hemicelluloses by these pretreatments, and simultaneously obtains lower pulp kappa numbers. The results indicated that when aiming to the same kappa numbers (i.e., kappa numbers 14.3-20.5), roughly 3% higher pulp yield could be achieved if the chips were pretreated with alkaline 0.5% NaBH4 solutions, compared…
Analysis of biological prognostic factors using tissue microarrays in neuroblastic tumors
2009
Background Neuroblastic tumors (NT) are pediatric neoplasms with a heterogeneous genetic profile. They present genotypic alterations of prognostic value, the study of which is mandatory in designing therapeutic management. Tissue microarrays (TMA) from paraffin material allow the analysis of a large number of cases with minimal costs. The main purpose of the present study is to analyze specific genetic markers of neuroblastic tumors included in TMAs and determine their prognostic value. We compare the results obtained by different molecular techniques at different substrates to evaluate the feasibility of these assays. Procedure One hundred thirty-nine samples were included in four differen…
Novel circulating microRNA signature as a potential non-invasive multi-marker test in ER-positive early-stage breast cancer:A case control study
2014
Introduction There are currently no highly sensitive and specific minimally invasive biomarkers for detection of early‐stage breast cancer. MicroRNAs (miRNAs) are present in the circulation and may be unique biomarkers for early diagnosis of human cancers. The aim of this study was to investigate the differential expression of miRNAs in the serum of breast cancer patients and healthy controls. Methods Global miRNA analysis was performed on serum from 48 patients with ER‐positive early‐stage breast cancer obtained at diagnosis (24 lymph node‐positive and 24 lymph node‐negative) and 24 age‐matched healthy controls using LNA‐based quantitative real‐time PCR (qRT‐PCR). A signature of miRNAs was…
Novel insights in the genetics of HCC recurrence and advances in transcriptomic data integration.
2011
Background & Aims: In approximately 70% of patients with hepatocellular carcinoma (HCC) treated by resection or ablation, disease recurs within 5 years. Although gene expression signatures have been associated with outcome, there is no method to predict recurrence based on combined clinical, pathology, and genomic data (from tumor and cirrhotic tissue). We evaluated gene expression signatures associated with outcome in a large cohort of patients with early stage (Barcelona-Clinic Liver Cancer 0/A), single-nodule HCC and heterogeneity of signatures within tumor tissues. Methods:We assessed 287 HCC patients undergoing resection and tested genome-wide expression platforms using tumor (n = 287)…

A 14-item Mediterranean diet assessment tool and obesity indexes among high-risk subjects: the PREDIMED trial
2012
Objective Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet) is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circum…
Colorectal cancer survival in the USA and Europe: a CONCORD high-resolution study
2013
Journal Article; OBJECTIVES: To assess the extent to which stage at diagnosis and adherence to treatment guidelines may explain the persistent differences in colorectal cancer survival between the USA and Europe. DESIGN: A high-resolution study using detailed clinical data on Dukes' stage, diagnostic procedures, treatment and follow-up, collected directly from medical records by trained abstractors under a single protocol, with standardised quality control and central statistical analysis. SETTING AND PARTICIPANTS: 21 population-based registries in seven US states and nine European countries provided data for random samples comprising 12 523 adults (15-99 years) diagnosed with colorectal ca…
Challenging management of gingival squamous cell carcinoma: a 10 years single-center retrospective study on Northern-Italian patients.
2020
Background Aim of this study was to describe the outcome of patients with gingival squamous cell carcinoma (GSCC), and to recognize aspects affecting clinical course and to consider survival rate. Material and Methods The case records of patients, over a 10-year period, were retrospectively examined. Differences in distribution of the potential risk factors by prognosis were investigated through non-parametrical tests (Wilcoxon Rank-Sum and Fisher’s Exact). Survival curves for age, therapy and stage were built by the Kaplan-Meier method and compared with Log-Rank test. Results 79 patients were analysed. Significant increase in mortality for patients older than 77 and for those with advanced…
Bioaccessibility of glucoraphanin from broccoli using anin vitrogastrointestinal digestion model
2014
This study investigated the effect of cooking methods on the degradation of glucoraphanin (GR) in broccoli and the bioaccessibility of this compound through simulated gastrointestinal digestion. Broccoli was cooked using three different techniques: boiling, steaming and microwave cooking. Then, GR was extracted and quantified by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). In addition, the cooked samples were added to a system that simulates the digestion characteristics of the mouth, stomach and duodenum. Samples were drawn before and after the digestion, and GR bioaccessibility was calculated. GR losses were higher when broccoli was boiled (47.03%), followed by …
786 Fertility-sparing and minimally invasive surgery in patients with stage I malignant ovarian germ cell tumours in Germany
2021
Introduction/Background* Malignant ovarian germ cell tumours (OGCT) often affect women of younger age at an early stage of disease who may desire fertility conservation. The Arbeitsgemeinschaft fuer Gynaekologische Onkologie (AGO) has established a clinicopathological (Current Ovarian geRm cell and SEx cord stromal Tumour Treatment strategies, CORSETT) database to describe treatment strategies and outcomes for these women. Methodology 20 German centres entered mixed retro- and prospective data of 56 FIGO stage I OGCT patients treated between 2000 to 2014 into the CORSETT database. An independent CORSETT pathology reference panel re-evaluated the primary histological diagnosis. A descriptive…
