Total tumor volume (TTV) has been proposed as a more accurate means of selecting patients for liver transplantation (LT) due to hepatocellular carcinoma (HCC). We aim to analyze the role of TTV in a population with a short waiting time on list. METHODS: Analysis of a prospective database of patients submitted to LT for HCC between September 1992 and February 2014. TTV, Milan criteria (MC), UCSF (University of California San Francisco), and "Up to Seven" criteria were calculated both with preoperative imaging exams and histological data...

Previous observations indicated that C3G (RAPGEF1) promotes α-granule release, evidenced by the increase in P-selectin exposure on the platelet surface following its activation. The goal of the present study is to further characterize the potential function of C3G as a modulator of the platelet releasate and its implication in the regulation of angiogenesis. Proteomic analysis revealed a decreased secretion of anti-angiogenic factors from activated transgenic C3G and C3G∆Cat platelets. Accordingly, the secretome from both transgenic platelets had an overall pro-angiogenic effect as evidenced by an in vitro capillary-tube formation assay with HUVECs (human umbilical vein endothelial cells) and by two in vivo models of heterotopic tumor growth...

PURPOSE OF REVIEW: To summarize and classify the most recent and relevant microbiological studies for each type of skin and soft tissue infection (SSTI). RECENT FINDINGS: Following Infectious Diseases Society of America and Food and Drug Administration classifications of SSTIs, we differentiate between two large groups, the superficial or uncomplicated infections and the complicated infections with deep involvement. It is not usually necessary to obtain microbiological samples in uncomplicated infections, except in cases of recurrences or for epidemiological control purposes...

Adam J Greteman, Sam Stiegler
In this article, Greteman and Stiegler explore the work of becoming queer within the Millennial generation. Collaborative in nature, their investigation turns to three key popular culture texts of the 1990s - Will and Grace, Rent, and MTV's Spring Break - that were central to their then emerging sense of self. Staged as an intragenerational conversation, the authors look to create space to unpack the connections, anecdotal by design, between popular texts and changing ideas of queer identity and community. Since neither author grew up within the confines of a gay ghetto - Boystown of Chicago, the Castro of San Francisco, the East Village of New York City - where they may have encountered and been enamored by the avant-garde queer subcultures so often praised in queer scholarship (for important reasons), they turn instead to experiences with popular culture that opened up lessons in becoming gay, in rural and Midwestern locales where queerness operated and emerged differently...

Plate tectonics and sediment processes control regional continental shelf topography. We examine the genetic consequences of how glacial-associated sea-level change interacted with variable near-shore topography since the last glaciation. We reconstructed the size and distribution of areas suitable for tidal estuary formation from the Last Glacial Maximum, ~20 thousand years ago, to present from San Francisco, California, USA (~38 °N) to Reforma, Sinaloa, Mexico (~25 °N). We assessed range-wide genetic structure and diversity of three co-distributed tidal estuarine fishes (California Killifish, Shadow Goby, Longjaw Mudsucker) along ~4,600 km using mitochondrial control region and cytB sequence, and 16-20 microsatellite loci from a total of 524 individuals...

Intense few- and single-cycle pulses are powerful tools in different fields of science Today, third- and higher-order terms in the remnant spectral phase of the pulses remain a major obstacle for obtaining high-quality few- and single-cycle pulses from in-line post-compression setups. In this Letter, we show how input pulse shaping can successfully be applied to standard post-compression setups to minimize the occurrence of high-order phase components during nonlinear propagation and to directly obtain pulses with durations down to 3 fs...

Drinking water can be exposed to different biological contaminants from the source, through the pipelines, until reaching the final consumer or industry. Some of these are pathogenic bacteria and viruses which may cause important gastrointestinal or systemic diseases. The microbiological quality of drinking water relies mainly in monitoring three indicator bacteria of faecal origin, Escherichia coli, Enterococcus faecalis and Clostridium perfringens, which serve as early sentinels of potential health hazards for the population...

Urban transportation systems are vulnerable to congestion, accidents, weather, special events, and other costly delays. Whereas typical policy responses prioritize reduction of delays under normal conditions to improve the efficiency of urban road systems, analytic support for investments that improve resilience (defined as system recovery from additional disruptions) is still scarce. In this effort, we represent paved roads as a transportation network by mapping intersections to nodes and road segments between the intersections to links...
