The surgical treatment of neuroendocrine tumors(NETs) draws on experience and guidelines more than on prospective randomized trials. The incidence of NET is increasing in all parts of the gastrointestinal tract. A variety of classifications introduced over the last decade may have led to difficulties in judging clinical relevance and determining the right surgical strategy. The North American Neuroendocrine Tumor Society and the European Neuroendocrine Tumor Society have developed usable guidelines from the available literature. For more than 20 years laparoscopy has developed as the gold standard for various surgical indications. Nevertheless, few trials have compared open and laparoscopic surgery with regard to NET. This review summarizes the recent literature on surgery for NET and incorporates the evidence on laparoscopy for cancer which might be also applied for NET.

This paper presents an algorithmic way of building complex membrane systems by coupling elementary membranes. Its application seems particularly valuable in the case of asynchronous membrane systems, since the resulting membrane system remains asynchronous. The composition method is based on a handshake mechanism implemented by using antiport rules and promoters.

In this paper we proceed with the multiscale analysis of semilinear damped stochastic wave motions. The analysis is made by combining the well-known sigma convergence method with its stochastic counterpart, associated to some compactness results such as the Prokhorov and Skorokhod theorems. We derive the equivalent model, which is of the same type as the micro-model. One of the novelties of the work is that the corrector problem is solved in the classical sense of distributions,thereby allowing numerical computations of the homogenized coefficients.
