Association of Epstein-Barr virus with nasopharyngeal carcinoma and current status of development of cancer-derived cell lines

It is well known that the Epstein-Barr virus (EBV) contributes directly to tumourigenesis in nasopharyngeal carcinoma (NPC), primarily in the undifferentiated form of NPC (WHO type III; UNPC or UC), which is commonly found in South East Asia. Unfortunately, research in NPC has been severely hampered by the lack of authentic EBV-positive (EBV+) human NPC cell lines for study. Since 1975, there have been more than 20 reported NPC cell lines. However, many of these NPC-derived cell lines do not express EBV transcripts in long-term culture, and therefore that finding may dispute the fundamental theory of NPC carcinogenesis. In fact, currently only one EBV+ human NPC cell line (C-666) in long-term culture has been reported. Hence, most of the NPC cell lines may not be representative of the disease itself. In order to better understand and treat NPC, there is an urgent need to develop more EBV+ human NPC cell lines. In this review, we discuss the authenticity of existing NPC cell lines and the impact of our understanding of NPC biology on the treatment of the disease and the relationship of EBV to NPC in the context of cell lines

EU Dairy Sector: Impact of Luxemburg Reform, EU Enlargement and Trade Negotiations

The EU dairy sector is facing a period of significant changes that are due to three major decisions: the EU enlargement, the Luxembourg reform and on-going WTO negotiations. To evaluate the impact of such changes we developed a model of the EU and world dairy industry. The model is composed of two modules that interact: a milk and beef supply module and a dairy industry module. In this paper we present the model and focus on elements that are crucial for a better understanding of the impact of reforms: quota rents in the EU, evolution of production in the new member states and trade policy.agricultural policy, dairy industry, partial equilibrium model, International Relations/Trade, C21, Q13, Q18,

Roadmap for Societal Engagement for Higher Education Institutions

Publicación derivada del siguiente Proyecto Europeo: Higher Education Institution for Societal Engagement. HEISE. http://www.mapsi.eu/heise/Higher education institutions (HEIs) play a key role in educating young people to understand the underlying values in societies and cultures, which create crucial abilities to foster social integration. To succeed in this, the teachers and students of HEIs need novel ways to increase intercultural understanding and social inclusion. Hence, in the project we aim to create a comprehensive educational model grounded in experiential and challenge based learning to increase the higher education institutions’ societal engagement (HEISE).This study was co-funded by the Erasmus+ programme of the European Union within the Strategic Partnership for Higher Education (grant no. 2016-1-EE01-KA203-017334; HEISE project)

Status of the ENUBET Project

The ENUBET Collaboration is designing the first “monitored neutrino beam”: a beam with an unprecedented control of the flux, energy and flavor of neutrinos at source. In particular, ENUBET monitors the νe production mostly by the detection of large angle positrons from three body semileptonic decays of kaons: K+ → e+π0νe. In this paper, we present the status of the Project and the 2018-2019 advances on proton extraction, transfer line, particle identification in the decay tunnel and beam performance

Immediate surgery compared with short-course neoadjuvant gemcitabine plus capecitabine, FOLFIRINOX, or chemoradiotherapy in patients with borderline resectable pancreatic cancer (ESPAC5):a four-arm, multicentre, randomised, phase 2 trial

BackgroundPatients with borderline resectable pancreatic ductal adenocarcinoma have relatively low resection rates and poor survival despite the use of adjuvant chemotherapy. The aim of our study was to establish the feasibility and efficacy of three different types of short-course neoadjuvant therapy compared with immediate surgery.MethodsESPAC5 (formerly known as ESPAC-5f) was a multicentre, open label, randomised controlled trial done in 16 pancreatic centres in two countries (UK and Germany). Eligible patients were aged 18 years or older, with a WHO performance status of 0 or 1, biopsy proven pancreatic ductal adenocarcinoma in the pancreatic head, and were staged as having a borderline resectable tumour by contrast-enhanced CT criteria following central review. Participants were randomly assigned by means of minimisation to one of four groups: immediate surgery; neoadjuvant gemcitabine and capecitabine (gemcitabine 1000 mg/m2 on days 1, 8, and 15, and oral capecitabine 830 mg/m2 twice a day on days 1-21 of a 28-day cycle for two cycles); neoadjuvant FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, folinic acid given according to local practice, and fluorouracil 400 mg/m2 bolus injection on days 1 and 15 followed by 2400 mg/m2 46 h intravenous infusion given on days 1 and 15, repeated every 2 weeks for four cycles); or neoadjuvant capecitabine-based chemoradiation (total dose 50·4 Gy in 28 daily fractions over 5·5 weeks [1·8 Gy per fraction, Monday to Friday] with capecitabine 830 mg/m2 twice daily [Monday to Friday] throughout radiotherapy). Patients underwent restaging contrast-enhanced CT at 4-6 weeks after neoadjuvant therapy and underwent surgical exploration if the tumour was still at least borderline resectable. All patients who had their tumour resected received adjuvant therapy at the oncologist's discretion. Primary endpoints were recruitment rate and resection rate. Analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN, 89500674, and is complete.FindingsBetween Sept 3, 2014, and Dec 20, 2018, from 478 patients screened, 90 were randomly assigned to a group (33 to immediate surgery, 20 to gemcitabine plus capecitabine, 20 to FOLFIRINOX, and 17 to capecitabine-based chemoradiation); four patients were excluded from the intention-to-treat analysis (one in the capecitabine-based chemoradiotherapy withdrew consent before starting therapy and three [two in the immediate surgery group and one in the gemcitabine plus capecitabine group] were found to be ineligible after randomisation). 44 (80%) of 55 patients completed neoadjuvant therapy. The recruitment rate was 25·92 patients per year from 16 sites; 21 (68%) of 31 patients in the immediate surgery and 30 (55%) of 55 patients in the combined neoadjuvant therapy groups underwent resection (p=0·33). R0 resection was achieved in three (14%) of 21 patients in the immediate surgery group and seven (23%) of 30 in the neoadjuvant therapy groups combined (p=0·49). Surgical complications were observed in 29 (43%) of 68 patients who underwent surgery; no patients died within 30 days. 46 (84%) of 55 patients receiving neoadjuvant therapy were available for restaging. Six (13%) of 46 had a partial response. Median follow-up time was 12·2 months (95% CI 12·0-12·4). 1-year overall survival was 39% (95% CI 24-61) for immediate surgery, 78% (60-100) for gemcitabine plus capecitabine, 84% (70-100) for FOLFIRINOX, and 60% (37-97) for capecitabine-based chemoradiotherapy (p=0·0028). 1-year disease-free survival from surgery was 33% (95% CI 19-58) for immediate surgery and 59% (46-74) for the combined neoadjuvant therapies (hazard ratio 0·53 [95% CI 0·28-0·98], p=0·016). Three patients reported local disease recurrence (two in the immediate surgery group and one in the FOLFIRINOX group). 78 (91%) patients were included in the safety set and assessed for toxicity events. 19 (24%) of 78 patients reported a grade 3 or worse adverse event (two [7%] of 28 patients in the immediate surgery group and 17 [34%] of 50 patients in the neoadjuvant therapy groups combined), the most common of which were neutropenia, infection, and hyperglycaemia.InterpretationRecruitment was challenging. There was no significant difference in resection rates between patients who underwent immediate surgery and those who underwent neoadjuvant therapy. Short-course (8 week) neoadjuvant therapy had a significant survival benefit compared with immediate surgery. Neoadjuvant chemotherapy with either gemcitabine plus capecitabine or FOLFIRINOX had the best survival compared with immediate surgery. These findings support the use of short-course neoadjuvant chemotherapy in patients with borderline resectable pancreatic ductal adenocarcinoma.FundingCancer Research UK

Brazilian Consensus on Photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of nonmelanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection

Riabilitazione neuropsicologica della persona con trauma cranio-encefalico lieve o moderato

Gli esiti disabilitanti dei Traumi Cranio-Encefalici (TCE) moderati o lievi rappresentano un problema di notevole rilevanza sanitaria e sociale nelle societ\ue0 moderne. Va considerata l\u2019elevata incidenza e prevalenza, specialmente tra adulti e giovani in piena et\ue0 scolastica o lavorativa. Inoltre, la numerosit\ue0 e complessit\ue0 delle conseguenze di tipo senso-motorio, comportamentale e cognitivo, sono spesso disabilitanti nella vita quotidiana. Importanti sono anche le ripercussioni emotive e materiali che vanno a gravare sul sistema famigliare della persona colpita. Le conseguenze sociali, in termini di difficolt\ue0 di reinserimento famigliare, scolastico o lavorativo, richiedono la necessit\ue0 di un elevato impegno di risorse, in ambito sociale e sanitario, con interventi complessi e prolungati nel tempo, che spesso devono essere modulati e diversificati in funzione degli specifici bisogni della persona cerebrolesa e del suo nucleo famigliare. Quest\u2019ultimo aspetto, soprattutto, costituisce un compito estremamente impegnativo sul piano tecnico-professionale, organizzativo e relazionale

The thiamine deficiency syndrome M74, a reproductive disorder of Atlantic salmon (Salmo salar) feeding in the Baltic Sea, is related to the fat and thiamine content of prey fish

This study clari\ufb01es how the diet of Baltic salmon leads to thiamine de\ufb01ciency in eggs, and consequently to M74 mortality of yolk-sac fry. The main prey species, sprat (Sprattus sprattus) and herring (Clupea harengus membras), and their biomass in the Baltic Proper (BPr) and the Bothnian Sea, the two feeding grounds of salmon originating from the northern Gulf of Bothnia rivers, are compared. The thiamine concentration of both prey species is lowest in the youngest age groups. Because average fat content and energy density are greater in sprat than in herring, and greatest in youngest sprat, the supply of thiamine per unit energy is least in a diet containing many young sprat. Also, the greater is the supply of thiamine and fat from sprat in the southern BPr in the preceding year, the lower the concentration of thiamine in salmon eggs. Thiamine de\ufb01ciency in eggs results from an unbalanced diet abundant in fatty prey \ufb01sh, such as young sprat, from which the supply of thiamine is insuf\ufb01cient in proportion to the supply of energy and unsaturated fatty acids for salmon, which must undergo a long prespawning fasting period
