BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has recently been developed to induce rapid liver hypertrophy to reduce the chance of post-hepatectomy liver failure in patients with borderline or insufficient future liver remnant. ALPPS is still in an early developmental stage and its techniques have not been standardized. This study aimed to review the technical modifications of the conventional ALPPS procedure. DATA SOURCES: Studies were identified by searching MEDLINE and PubMed for articles published from January 2007 to December 2016 using the keywords 'associating liver partition and portal vein ligation for staged hepatectomy' and 'ALPPS'. Additional articles were identified by a manual search of references from key articles. RESULTS: There have been a lot of modifications of the conventional ALPPS. These are classified as: (1) modifications aiming to improve surgical results; (2) modifications aiming to expand surgical indications; (3) salvage ALPPS; (4) ALPPS using the minimally invasive approach. Some of these modifications have made the conventional ALPPS procedure to become even more complex, although there have also been other attempts to make the procedure less complex. The results of most of these modifications have been reported in small case series or case reports. We need better well-designed studies to establish the true roles of these modifications. However, it is interesting to see how this conventional ALPPS procedure has evolved since its introduction. CONCLUSIONS: There is a trend for the use of minimally invasive procedure in the phase 1 or 2 of the conventional ALPPS procedure. Some of these modifications have expanded the use of ALPPS in patients who have been considered to have unresectable liver tumors. The long-term oncological outcomes of these modifications are still unknown.

Male and female differ genetically by their respective sex chromosome composition, that is, XY as male and XX as female. Although both X and Y chromosomes evolved from the same ancestor pair of autosomes, the Y chromosome harbors male-specific genes, which play pivotal roles in male sex determination, germ cell differentiation, and masculinization of various tissues. Deletions or translocation of the sex-determining gene, SRY, from the Y chromosome causes disorders of sex development （previously termed as an intersex condition） with dysgenic gonads. Failure of gonadal development results not only in infertility, but also in increased risks of germ cell tumor （GCT）, such as gonadoblastoma and various types of testicular GCT. Recent studies demonstrate that either loss of Y chromosome or ectopic expression of Y chromosome genes is closely associated with various male-biased diseases, including selected somatic cancers. These observations suggest that the Y-linked genes are involved in male health and diseases in more frequently than expected. Although only a small number of protein-coding genes are present in the male-specific region of Y chromosome, the impacts of Y chromosome genes on human diseases are still largely unknown, due to lack of in vivo models and differences between the Y chromosomes of human and rodents. In this review, we highlight the involvement of selected Y chromosome genes in cancer development in men.

"Grid" computing has emerged as an important new research field. With years of efforts, grid researchers have successfully developed grid technologies including security solutions,resource management protocols, information query protocols, and data management services. However, as the ultimate goal of grid computing is to design an infrastructure which supports dynamic,cross-organizational resource sharing, there is a need of solutions for efficient and transparent task re-scheduling in the *** this research, a new grid middleware is proposed, called G-JavaMPI. This middleware adds the parallel computing capability of Java to the grid with the support of a Grid-enabled message passing interface (MPI) for inter-process communication between Java processes executed at different grid points. A special feature of the proposed G-JavaMPI is the support of Java process migration with post-migration message redirection. With these supports, it is possible to migrate executing Java process from site to site for continuous computation, if some site is scheduled to be turned down for system reconfiguration. Moreover, the proposed G-JavaMPI middleware is very portable since it requires no modification of underlying OS, Java virtual machine, and MPI package. Preliminary performance tests have been conducted. The proposed mechanisms have shown good migration efficiency in a simulated grid environment.

Despite carbonaceous materials are widely employed as commercial negative electrodes for lithium ion battery, an urge requirement for new electrode materials that meet the needs of high energy density, long cycle life, low cost and safety is still underway. A number of cobalt-based compounds（Co（OH）_2, Co_3O_4, CoN, CoS,CoP, NiCo_2O_4, etc.） have been developed over the past years as promising anode materials for lithium ion batteries（LIBs） due to their high theoretical capacity, rich redox reaction and adequate cyclability. The LIBs performances of the cobalt-based compounds have been significantly improved in recent years, and it is anticipated that these materials will become a tangible reality for practical applications in the near future. However, the different types of cobalt-based compounds will result in diverse electrochemical performance. This review briefly analyzes recent progress in this field, especially highlights the synthetic approaches and the prepared nanostructures of the diverse cobalt-based compounds and their corresponding performances in LIBs, including the storage capacity, rate capability, cycling stability and so on.

In most urban redevelopment projects that take place in Hong Kong, the Urban Renewal Authority (URA) will offer compensation to an owner-occupier based on the market value of the property. The basis of market value assessment is defined as a seven-year-old flat in a comparable quality building, situated in a similar locality in terms of characteristics and accessibility, and located at the middle floor with average orientation. However, little was done in exploring the application and the integration of mass valuation technique in the compulsory acquisition valuation area. This paper endeavors to illustrate the prospects of using mass valuation techniques to value high-rise and strata-title dilapidated buildings by adopting a standardization statistical method to derive resumption estimates.

Thrombin is a pivotal molecule in acute myocardial infarction ( Ml) because of its extensive procoagulant and prothrombotic actions. Antithrombin therapy is an important component of the pharmacotherapy for acute Ml. The standard agent used in clinical practice, unfractionated heparin (UFH), is associated with the disadvantages of variable anticoagulant effect, inability to inhibit clot-bound thrombin, neutralization by platelet factor 4, and the propensity to cause thrombocytopenic complications. Novel thrombin inhibitors have been developed to overcome these disadvantages. Although possessing the property of inhibiting both fluid-phase and clot-bound thrombin, the direct thrombin inhibitor hirudin has been shown to give marginal benefits over UFH as adjunct to fibrinolysis in ST-elevation Ml. Bivalirudin, another direct thrombin inhibitor, is able to reduce reinfarction in patients treated with streptokinase and is a new anticoagulant treatment option in this setting. The pharmacokinetic characteristics of better availability, longer half-life, and dose-independent clearance together with the ability of inhibiting both thrombin generation and activity make the low-molecular-weight heparins (LMWHs) an attractive alternative to UFH. The favorable benefit/risk profile of the LMWHs as adjunct to different generations of fibrinolytic agents is setting the stage for larger clinical trials to confirm their role as the antithrombin agent of choice for STEMI.
