The corrosion resistance of three Mg alloys containing rare-earth elements(WE43,EV31 and ZE41)was studied and compared to that of two Mg-Al alloys(AZ31 and AZ91)and of pure Mg(99.95 wt.%).Current-voltage curves and electrochemical impedance measurements were performed with rotating disk electrodes in an aerated 0.1 M Na_(2)SO_(4)*** all the alloys,it was confirmed that the intermetallic particles acted as local cathodes and that more protective films were formed on the alloys surface by comparison with the pure *** rates were determined from inductive coupled plasma-optical emission spectroscopy measurements and from the electrochemical *** corrosion rates were observed for the rare-earth Mg alloys compared to the AZ series *** data allowed the corrosion mechanisms to be discussed.

The Guole biota contains common shelly fossils and some exceptionally well-preserved softbodied fossils. Stratigraphically, it is located in the mudstones and siltstones of the Sandu Formation near Guole Town, Jingxi County, Guangxi, South China. It is the first Furongian （late Cambrian） Burgess Shale-type biota found in the world, thereby filling the gap between middle Cambrian and Lower Ordovician Burgess Shale-type Lagerstaitten. Preliminary studies suggest that the Guole biota includes approximately seven metazoan groups as well as algae. These will provide important new evolutionary and ecological information.

BACKGROUND Pancreaticoduodenectomy(PD)-induced morbidity, consisting mainly of the pancreatic fistula and its hemorrhagic and infectious consequences, is well described in the literature, in terms of its definition, risk factors, preventive measures, and standardized management of complications. However, some lifethreatening complications remain atypical and undescribed. CASE SUMMARY We report here the case of a 69-year-old patient with Budd-Chiari syndrome that occurred after arterial embolization of postpancreatectomy hemorrhage. Diagnosis was established with biological findings(i.e., acute liver failure) and radiological findings(i.e., compressive hematoma of the retrohepatic vena cava). Emergency surgical revision was performed to evacuate the hematoma. The postoperative course was uneventful, with rapid recovery of liver function. To our knowledge, post-PD Budd-Chiari syndrome has never been described in the literature. CONCLUSION Acute liver failure in early post-PD should prompt investigation to rule out Budd-Chiari syndrome.

We read with interest the recently published paper by Chebaro et al.(1).The authors compared liver venous deprivation(LVD)and associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)which are two novel techniques used to achieve increased hypertrophy of the future liver remnant(FLR)in view of extensive liver resections(2,3).
