Surgical treatment of early breast cancer in day surgery.

2007

Quadrantectomy and associated sentinel lymph node biopsy (SLNB) is currently employed in most breast surgery centres as the gold standard in the treatment of early breast cancer. This approach has a modest morbidity and can usually be performed in a day-surgery regimen, leading to best acceptance by the patients. This reports outlines the experience of our Breast Unit with quadrantectomy and SLNB in day surgery for early breast cancer. One hundred patients presenting to our institution with primary invasive breast cancer measuring less than 3 cm and clinically negative axillary nodes underwent quadrantectomy and SLNB in day surgery. For 60 women with breast cancer the sentinel node was nega…

Enhanced Lipid Peroxidation and Platelet Activation in the Early Phase of Type 1 Diabetes Mellitus

2003

Background— To investigate early events possibly related to the development of diabetic angiopathy, we examined whether 8-iso-prostaglandin F 2α (8-iso-PGF 2α ) formation, a marker of in vivo oxidant stress, is altered in different stages of type 1 diabetes (T1DM) and whether it correlates with the rate of thromboxane (TX) A 2 biosynthesis, a marker of in vivo platelet activation. We also investigated the relationship between inflammatory markers and F 2 -isoprostane formation in this setting. Methods and Results— A cross-sectional study was performed in 23 insulin-treated patients aged <18 years with new-onset T1DM (≤6 weeks, group A), matched for age and gender with 23 patients with s…

The Impact of the Progressive Efficiency Test on a Rowing Ergometer on White Blood Cells Distribution and Clinical Chemistry Changes in Paralympic Ro…

2017

Abstract There is a large gap in knowledge regarding research on post-exercise blood changes in disabled athletes. There are relatively few data on adaptive mechanisms to exercise in disabled athletes, including disabled rowers. Two rowers from a Polish adaptive rowing settle TAMix2x that qualified for the Paralympic Games in Rio, 2016 took part in this study. They performed a progressive test on a rowing ergometer until exhaustion. The cardiorespiratory fitness measures, complete blood count, white blood cells’ distribution and 30 clinical chemistry variables describing laboratory diagnostic profiles and general health were determined. The extreme effort induced changes in all studied meta…

The case of cusà in Sicilian: From interrogative clause to epistemic adverb and discourse marker

Extracting (good) discourse examples from an oral specialised corpus of wine tasting interactions

2015

International audience; This article outlines the semi-automated extraction of dictionary examples used in the compilation of a professional online dictionary of wine tasting. Named OenoLex Bourgogne, this dictionary was started to respond to the demand for a lexicographic information tool from the French wine industry of Burgundy, the Bureau Interprofessionnel des Vins de Bourgogne.

Eating patterns are associated with biomarkers in a selected population of university students and employees.

2011

AbstractThe association between diet and CVD cannot be assigned to a single nutrient, but rather to a set of nutrients and non-nutrients, and eating pattern analyses have become an important tool in investigation of this relationship. Our objective was to investigate eating patterns in relation to nutrient intake and serum concentration of folate, vitamin B12 and TAG in ninety-five healthy adult participants. Dietary information was collected by an FFQ, and eating patterns were obtained by principal components analyses of thirty-three food groups. Three eating patterns were extracted, a sweet eating pattern identified by intakes of cakes, snacks, sugar-sweetened drinks and chocolates; a pru…

Ensayo clínico multicéntrico, aleatorizado y enmascarado con topiramato versus placebo para el tratamiento de recién nacidos con encefalopatía hipóxi…

2021

Antecedentes: La encefalopatía hipóxico-isquémica (EHI) perinatal constituye una de de las principales causas de muerte o discapacidad a largo plazo en recién nacidos a término en el mundo occidental, afectando a aproximadamente 1-4 por cada 1000 nacidos vivos y, en consecuencia, a alrededor de 5000-20000 recién nacidos por año en Europa. La hipotermia terapéutica se ha convertido en el tratamiento estándar de la EHI moderada o grave, siendo una terapia segura y eficaz para mejorar el desarrollo neurológico tras un insulto hipóxico-isquémico perinatal. A pesar de la hipotermia y las mejoras en los cuidados intensivos neonatales, el 45-50% de los recién nacidos con EHI moderada o grave muere…

Serum miRNAs in women affected by hyperandrogenic polycystic ovary syndrome: the potential role of miR-155 as a biomarker for monitoring the estropro…

2018

MicroRNAs can be used as very efficient circulating biomarkers. The role of microRNAs in polycystic ovary syndrome (PCOS) and the effects of antiandrogen therapy on microRNA expression is still not fully understood. A panel of serum microRNAs were retrotranscribed via looped reverse primer transcription specific for each miRNA and quantified via probe specific RT-PCR in 16 Caucasian hyperandrogenic PCOS women selected according to the Rotterdam criteria and in a subset of seven patients after four months of sequential reverse antiandrogenic therapy. All women recruited underwent an oral glucose tolerance test (OGTT) and a baseline total cholesterol, high density lipoproteins cholesterol, tr…

Extracellular heat shock proteins in cancer: From early diagnosis to new therapeutic approach

2021

In cancer, human cells lose the ability to properly control the series of events that occur constantly during cell growth and division, including protein expression, stability, and dynamics. Heat shock proteins (Hsps) are key molecules in these events, constitutively expressed at high levels and could furthermore be induced by the response to cancer-induced stress. In tumor cells, Hsps have been shown to be implicated in the regulation of apoptosis, immune responses, angiogenesis and metastasis; in some cases, they can be overexpressed and dysregulated, representing important cancer hallmarks. In the past few years, it has been demonstrated that Hsps can be released by tumor cells through s…

Role of quercetin on sterigmatocystin-induced oxidative stress-mediated toxicity.

2021

Oxidative stress appears to be a common trigger for many of the effects associated with the exposure to various mycotoxins, including sterigmatocystin (STE). However, studies to alleviate STE toxicity through the use of natural antioxidants are sparsely reported in literature. In the present study, the cytoprotective effect of quercetin (QUE) was tested in SH-SY5Y cells against STE-induced oxidative stress and cytotoxicity. The MTT assay revealed that STE decreased cell viability, whereas pre-treatment of cells with QUE restored it. The QUE was also found to counteract STE-induced ROS generation and decrease STE-induced up-regulation of the expression of the stress-inducible enzymes HO-1 an…
