In the past two decades, the management of rectal cancer has made important progress, highlighting the main role of a multimodality strategy approach, combining surgery, radiation therapy and chemotherapy. Nowadays, surgery remains the primary treatment and neoadjuvant chemoradiotherapy, based on fluoropyrimidine(5-FU) continuous infusion, is considered the standard in locally advanced rectal carcinoma. The aim is to reduce the incidence of local recurrence and to perform a conservative surgery. To improve these purposes different drugs combination have been tested in the neo-adjuvant setting. At American Society of Clinical Oncology 2014 an important abstract was presented focusing on the role of adding oxaliplatin to concomitant treatment, in patients with locally advanced rectal carcinoma. Rodel et al reported on the CAO/ARO/AIO-04 randomized phase Ⅲ trial that compared standard treatment with 5-FU and radiation therapy, to oxaliplatin plus 5-FU inassociation with radiation therapy. The addition of oxaliplatin to the neo-adjuvant treatment has been shown to improve disease-free survival from 71.2% to 75.9%(P = 0.03). This editorial was planned to clarify the optimal treatment in patients with locally advanced rectal cancer, considering the results from CAO/ARO/AIO-04 study.展开更多

For comparison, when only pure carbon dioxide was introduced using the conventional CVD method without integrated process, no solid-form carbon-material product could be formed. In the addition of saturated steam at room temperature in the feed for CVD, there were much more end-opening carbon nano-tubes produced, at a slightly higher carbon yield. These inspiring works opened a remarkable and alternative new approach for carbon dioxide catalytic capture to solid-form product, comparing with that of CO2 sequestration (CCS) or CO2 mineralization (solidification), etc. As a result, there was much less body volume and almost no greenhouse effect for this solid-form carbon-material than those of primitive carbon dioxide.展开更多

MPSS use for SCI has since become very controversial and it is our opinion that additional evidence is unlikely to break the stalemate amongst clinicians. Patient opinion has the potential to break this stalemate and we review our recent findings which reported that spinal cord injured patients informed of the risks and benefits of MPSS reported a preference for MPSS administration. We discuss the implications of the current MPSS debate on translational research and seek to address some misconceptions which have evolved. As science has failed to resolve the MPSS debate we argue that the debate is an increasingly philosophical one. We question whether SCI might be viewed as a serious condition like cancer where serious side effects of therapeutics are tolerated even when benefits may be small. We also draw attention to the similarity between the side effects of MPSS and isotretinoin which is prescribed for the cosmetic disorder acne vulgaris. Ultimately we question how patient autonomy should be weighed in the context of current SCI guidelines and MPSS's status as a historical standard of care.展开更多

Helping farmers lose less of their crops will be a key factor in promoting food security. In addition to pesticides GM crops will continue to be a vital tool in the diverse range of technologies that can maintain and improve living standards for the people of the world. The EU is dependent for 65% on imports of protein-rich feedstuffs for which there are no substitutes in the short term. The EU livestock sector uses imported soybean, soybean meal and maize by-products as animal feed. Without an adequate supply of these feed ingredients, the EU’s livestock production will loose competitiveness. However, demands from the EU differ to those from third countries with respect to the GM varieties grown, and what are authorised for import into the EU. The risk that supplies of soya products and maize by-products could be affected by the low-level presence of non-EU approved GM material has not been fully resolved as the EU has allowed just a 0.1% tolerance for this plus 0.05% tolerance for measuring uncertainty. This could cause supply problems for the animal feed industry, and ultimately supply of food to consumers. The importance of the EU market and EU requirements for the major soybean and maize exporter countries is declining over time and it is becoming increasingly difficult and costly to maintain a non-GM supply chain in the EU. Food companies and supermarkets will struggle to stay GM-free. EU member states dependent on imports will be forced to deal with more GM presence in their chain. Market forces are forcing governments to authorize products more efficiently, develop tolerance policies or tolerate unapproved varieties in their imports.展开更多
