Hepatic resection represents the gold-standard treatment for different liver diseases. Among postoperative complications, bile leak remains one of the most common sources of morbidity, which can lead to an increase of hospital stay, need of invasive procedure and potentially death (1). The definition and acknowledge of risk factors for the development of biliary fistula as well as its early detection and optimal management is, in this sense, of crucial importance.

Minimal access liver surgery(MALS),is now routinely performed worldwide,and procedures like limited resections of antero-inferior segments and left lateral sectionectomy could be retained as standard once performed laparoscopically(1).It is a common believe that MALS procedures mean shorter and better postoperative outcome,and essentially more safety compared to the open ***,MALS procedures facing with complex disease presentations are increasingly proposed(2).In this escalation of MALS in the panorama of the surgical offer available for patients with liver tumors open liver surgery(OLS)seems somehow passed *** this setting,the paper of Tong et *** to set clinically based criteria for allowing to foresee the risk of conversion and morbidity once a MALS is planned(3).At least the attempt is worth to be awarded while the results should be validated by means of further studies able to test the scoring system the authors *** sure there is the merit to investigate the burden of MALS,which implies the recognition of a limit and subsequently the need for its precise definition.A definition which,as anything in medicine,could not be considered definitive,since it will probably evolve with expertise and technology as it has been the case in the last 10-15 ***,pointing out the existence of a limit superimposes caution to any effort to get over the burden unless the attempt is based on a solid *** sure,in this sense,the authors have provided an instrument for the surgical community which conveys limits to which any surgeon has to face with.

The use of contrast-enhanced intraoperative ultrasound for hepatocellular carcinoma has been already proposed as a novel technique to stage the disease during surgical resection. In the herein presented "letter to the editor", the authors underline some important points, which have been raised following paper published in the January issue of World Journal of Gastroenterology.

Let G be a complex connected reductive group. Losev has shown that a smooth affine spherical G-variety X is uniquely determined by its weight monoid, which is the set of irreducible representations of G that occur in the coordinate ring of X. In this paper we use a combinatorial characterization of the weight monoids of smooth affine spherical varieties to classify：（a） all such varieties for G = SL（2） × C~×and（b） all such varieties for G simple which have a G-saturated weight monoid of full rank. We also use the characterization and Knop＇s classification theorem for multiplicity free Hamiltonian manifolds to give a new proof of Woodward＇s result that every reflective Delzant polytope is the moment polytope of such a manifold.

Ga-Al-MFI samples were synthesized in hydrothermal conditions from gels of composition 1.08CH3NH2- 0.134TPABr-1SiO2-xAl2O3-yGa2O3-40H2O at 175 ℃ for 7 days, with x = 0.005 and 0.0025, y = 0.005, 0,010 and 0.020. The samples were characterized by XRD, BET measurements, thermal analysis （TGA-DTA） atomic absorption and high resolution solid state MAS 27Al and 71Ga NMR measurements. The aromatization of propane was studied as catalytic test. The activity and selectivity of the catalysts were determined for benzene, toluene and xylenes on the one hand and for methane and ethane on the other hand. The most active sample was obtained with the highest Ga/AI ratio. For this sample, the BTX selectivity obtained by aromatization was always higher than the hydrocracking selectivity leading to methane and ethane. The relative amount of toluene was higher than that of benzene and ofxylenes. The samples were deactivated by coke formation that was revealed more severe for the most active sample,

This review examines the biological properties of coumarins, widely distributed at the highest levels in the fruit, followed by the roots, stems and leaves, by considering their beneficial effects in the prevention of some diseases and as anti-cancer agents. These compounds are well known photosensitizing drugs which have been used as pharmaceuticals for a broad number of therapeutic applications requiring cell division inhibitors. Despite this, even in the absence of ultraviolet rays they are active. The current paper mainly focuses on the effects of psoralens on human breast cancer as they are able to influence many aspects of cell behavior, such as cell growth, survival and apoptosis. In addition, analytical and pharmacological data have demonstrated that psoralens antagonize some metabolizing enzymes, affect estrogen receptor stability and counteract cell invasiveness as well as cancer drug resistance. The scientific findings summarized highlight the pleiotropic functions of phytochemical drugs, given that recently their target signals and how these are modified in thecells have been identified. The encouraging results in this field suggest that multiple modulating strategies based on coumarin drugs in combination with canonical chemotherapeutic agents or radiotherapy could be a useful approach to address the treatment of many types of cancer.
