BACKGROUND To analyze setup deviations using daily megavoltage computed tomography (MVCT) and to evaluate three MVCT frequency reducing protocols for gynecologic cancer patients treated with helical tomotherapy. METHODS We recorded the setup errors of 56 patients with gynecological cancer observed throughout their whole course by matching their daily MVCT with the planning CT. Systematic and ...

Dental diseases are among the most prevalent afflictions of humankind. These diseases are associated with the formation of biofilms harboring pathogenic bacteria. Fructosyltransferases (FTF) are extra cellular enzymes of several oral bacteria. FTF are associated with the formation of extracellular polysaccharide matrix (fructans) which play a role in biofilm formation and oral bacteria physiolo...

UNLABELLED Balance of labile methyl groups (choline, methionine, betaine, and folate) is important for normal liver function. Quantitatively, a significant use of labile methyl groups is in the production of phosphatidylcholines (PCs), which are ligands for the nuclear liver receptor homolog-1 (LRH-1). We studied the role of LRH-1 in methyl-pool homeostasis and determined its metabolic effects ...

Liver receptor homolog 1 (LRH-1) is an orphan nuclear receptor that synergizes with beta-catenin/T cell factor 4 signaling to stimulate intestinal crypt cell renewal. We evaluated here the impact of haploinsufficiency of LRH-1 on intestinal tumorigenesis by using two independent mouse models of human colon tumorigenesis. Haploinsufficiency of LRH-1 blunts intestinal tumorigenesis in the ApcMin/...

Video watermarking is usually considered as watermarking of a set of still images. In frame-by-frame watermarking approach, each video frame is seen as a single watermarked image, so collusion attack is more critical in video watermarking. If the same or redundant watermark is used for embedding in every frame of video, the watermark can be estimated and then removed by watermark estimate remod...

This study investigates the reporting of premarital sex in rural southern Malawi. It summarizes the results of an interview-mode experiment conducted with unmarried young women aged 15-21 in which respondents were randomly assigned to either an audio computer-assisted self-interview (ACASI) or a conventional face-to-face (FTF) interview. In addition, biomarkers were collected for HIV and three ...

The functional interaction between the orphan nuclear receptors small heterodimer partner (SHP) and liver receptor homolog 1 (LRH-1), where SHP binds to LRH-1 and represses its constitutive transcriptional activity, is crucial for regulating genes involved in cholesterol homeostasis. Here, we report structural and biochemical analyses of the LRH-1/SHP interaction. The crystal structure and mode...

This article examines a set of interactions (logs) takenfrom t h e f a n of computer-mediated communicntion known as Internet Relay Chat (IRC). The authors were particularly concerned with the interaction management strategies adopted by the participants in the logs during the opening and closing phases of the interactions to d m l o p interpersonal relationships and communicate socioemotional ...

Fructosyltransferase (FTF) enzymes produce fructose polymers (fructans) from sucrose. Here, we report the isolation and characterization of an FTF-encoding gene from Lactobacillus reuteri strain 121. A C-terminally truncated version of the ftf gene was successfully expressed in Escherichia coli. When incubated with sucrose, the purified recombinant FTF enzyme produced large amounts of fructo-ol...

In 2013, the Administration issued the Freeze the Footprint (FTF) policy to freeze the Federal Government's real estate footprint and restrict the growth of excess or underutilized properties. Freeze the Footprint was the first government-wide policy that established and required federal agencies to identify offsets (i.e., disposals) of existing property to support new property acquisitions, an...
