Retroperitoneal cysts are rare, usually asymptomatic, lesions. We present the case of a 42-year-old woman with an asymptomatic abdominal mass. The mass excised at our district hospital was found in the retroperitoneum. Histologically, the cyst was lined with benign Mullerian-type epithelium. The classification, aetiology and clinical manifestations of retroperitoneal cysts are discussed. Retroperitoneal cysts present as an acute abdomen in only a minority of cases. Ultrasound is the most reliable test for their detection, usually followed by computed tomography and/or an upper gastrointestinal series. Optimally, these cysts should be completely excised.

From the Publisher: Samba is a cross-platform triumph: it turns a Unix or Linux system into a file and print server for Microsoft Windows network clients. Now you can let users store their files (and even important executables) in a single place for easy sharing and backup, protected by Unix or NT security mechanisms, and still offer such transparent access that PC users don't even realize they're going to another system. This book describes all the options for Samba's configuration file in quick-reference format. It also contains command-line options and related information on the use of the Samba daemons (smbd and nmbd) and the utilities in the Samba distribution (smbsh, smbclient, smbstatus, smbtar nmblookup, smbpasswd, testparm, testprns, rpcclient, and a version of tcpdump enhanced to interpret the protocol used by Samba). System administrators who are familiar with Samba and want a handy reminder of how to administer it without the bulk of a full-sized book will find this pocket reference invaluable.

Many people are trying to be smarter every day. How's about you? There are many ways to evoke this case you can find knowledge and lesson everywhere you want.

This study investigates the molecular features of metastasis in sporadic colon carcinomas with high‐level microsatellite instability (MSI‐H). DNA from 51 regions from 10 MSI‐H metastatic carcinomas and 26 corresponding metastases was analyzed for mutations in TGFBRII, IGFIIR, BAX, MSH3, MSH6, and TCF4, which are associated with MSI‐H carcinomas. In addition, 10 metastatic and 10 non‐metastatic MSI‐H carcinomas and 10 metastatic microsatellite‐stable (MSS) carcinomas were examined for expression of vascular endothelial growth factor (VEGF) and mutant TP53. The frequency of microsatellite instability and somatic mutations was not significantly increased in the metastases compared with the that of primary carcinomas. Although significantly fewer MSI‐H carcinomas expressed VEGF (P < 0.01) and mutant TP53 (P < 0.005) than MSS carcinomas, there was no difference in VEGF and mutant TP53 expression in metastatic and non‐metastatic MSI‐H carcinomas. In conclusion, metastasis does not appear to be associated with an increase in somatic mutation rate in any of the genes examined in MSI‐H colon carcinomas. Furthermore, VEGF and TP53 expression did not appear to be involved in metastasis in MSI‐H colon carcinomas. © 2003 Wiley‐Liss, Inc.

From the Publisher:Using Samba, which has been officially adopted by the Samba Team and is under the GNU Free Documentation License (FDL), is a comprehensive guide to Samba administration. The current edition focuses on Samba 2.2 and covers the most important features of 3.0, which was under development as this book went to print. Samba is a cross-platform triumph: it turns a Unix or Linux system into a file and print server for Microsoft Windows network clients. Samba is so robust, flexible, fast, and secure that many people are choosing it over Windows NT/2000/XP for their file and print services. Samba is also free software, licensed under the GNU General Public License. This book will help you make file and print sharing as robust, powerful, and efficient as possible. The authors delve into the internals of the Windows activities and protocols to an unprecedented degree, explaining the strengths and weaknesses of each feature in Windows domains and in Samba itself. Using Samba takes you from basic installation and configuration -- on both the client and server side, for a wide range of systems -- to subtle details of security, cross-platform compatibility, and resource discovery that make the difference between whether a user sees the folder they expect or a cryptic error message. The range of this book knows few bounds. Wondering how to integrate Samba's authentication with that of a Windows PDC? How to get Samba to serve Microsoft Dfs shares? How to share files on Mac OS X? These and a dozen other issues of interest to system administrators are covered. A whole chapter is dedicated to troubleshooting. Whether you're playing on one note or a full three-octave range, on your personal computer or an enterprise network, Using Samba will give you an efficient and secure server.

From the Publisher:The Java 2 Enterprise Edition (J2EE) APIs have changed the way we think about enterprise computing. However, many programmers are discovering that simply learning the J2EE APIs isn't enough anymore. Writing efficient, robust enterprise code using servlets, JDBC, XML, EJB, and JSP can be a daunting task. In fact, it seems that the only way to become an expert at coding J2EE applications is to suffer through years of trial-and-error. Not anymore. Java Enterprise Best Practices helps to alleviate that frustration by offering you the benefit of our own authors' experience. This book recognizes the difference between learning a set of Java Enterprise libraries and learning how to use them both effectively and efficiently in your distributed applications.

Although microsatellite instability (MSI) has been shown to be present in 15% of sporadic colorectal carcinomas, the genetic events underlying the development of these tumors have not been well described. By investigating intratumoral heterogeneity, this study attempts to elucidate whether MSI-positive colorectal carcinomas develop as the result of a random accumulation of mutations or as an ordered, stepwise sequence of genetic alterations. Eighty-six regions from 16 MSI-positive sporadic colorectal carcinomas were examined for mutations in repeat nucleotide sequences of the tumour suppressor genes transforming growth factor beta type II receptor (TGFBRII), insulin-like growth factor II receptor (IGFIIR), and BAX, and the mismatch repair genes MSH3 and MSH6. At least 2 and up to 5 of these genes were mutated in each tumour, and widespread intratumoral heterogeneity was observed for each gene. Regions of tumour with TGFBRII mutations were correlated with a poorly differentiated histology. Unlike the situation in microsatellite stable colorectal carcinomas, the findings of the present study did not suggest that a particular sequence of tumour suppressor and mismatch repair genes are mutated during colorectal tumorigenesis. It seems likely that a random accumulation of mutations, as a result of a defect in the mismatch repair pathway, drives tumour progression in this type of colorectal carcinoma.
