An acylsemicarbazide-based porous organic polymer (POP) was facilely prepared by the polymerization of benzene-1,3,5-tricarbohydrazide (BTZ) and 1,4-phenylene diisocyanate (PDI). The physical properties of as-synthesized material were characterized by Fourier-transform infrared spectroscopy (FT-IR), solid-state cross polarisation magic angle spinning carbon-13 nuclear magnetic resonance (CP-MAS (13)C NMR), nitrogen adsorption/desorption measurement, water contact angle and so on. The specific surface area was 166 m(2)/g, and the water contact angle was 46...

AIMS: To report on the long-term occurrence of secondary compartment pelvic organ prolapse (POP) after open mesh sacrocolpopexy (MSC). METHODS: A prospectively maintained, IRB-approved database of non-neurogenic women with symptomatic triple compartment POP who underwent open MSC between 1999 and 2011 and had a 1-year minimum follow-up was reviewed. Length of follow-up was categorized as: intermediate (1-3 yr), late (3-5 yr), and very late (>5 yr). Demographic data, history of POP repairs, exam with Baden-Walker grading, validated questionnaires (Urogenital Distress Inventory short form [UDI-6], QoL), and outcomes at each follow-up visit were recorded...

Polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) are classical myeloproliferative neoplasms (MPN), characterized by specific somatic mutations in JAK2, CALR or MPL genes. JAK2 46/1 and TERT rs2736100 polymorphisms are known to significantly predispose to MPN. This study aimed to establish the additional contribution of the recently described MECOM rs2201862, HBS1L-MYB rs9376092 and THRB-RARB rs4858647 polymorphisms to the occurrence of MPN. These three polymorphisms, along with JAK2 46/1 and TERT rs2736100 were genotyped in 939 MPN patients (454 with ET, 337 with PV and 148 with PMF) and 483 controls...

Objects that are highly distinct from their surroundings appear to visually "pop-out." This effect is present for displays in which: (1) a single cue object is shown on a blank background, and (2) a single cue object is highly distinct from surrounding objects; it is generally assumed that these 2 display types are processed in the same way. To directly examine this, we applied a decoding analysis to neural activity recorded from the lateral intraparietal (LIP) area and the dorsolateral prefrontal cortex (dlPFC)...

Recent decline of sea ice habitat has coincided with increased use of land by polar bears (Ursus maritimus) from the southern Beaufort Sea (SB), which may alter the risks of exposure to pathogens and contaminants. We assayed blood samples from SB polar bears to assess prior exposure to the pathogens Brucella spp., Toxoplasma gondii, Coxiella burnetii, Francisella tularensis, and Neospora caninum, estimate concentrations of persistent organic pollutants (POPs), and evaluate risk factors associated with exposure to pathogens and POPs...

Pacific Ocean trawl samples, stomach contents of laboratory-raised fish as well as fish from the subtropical gyres were analyzed by Raman micro-spectroscopy (RMS) to identify polymer residues and any detectable persistent organic pollutants (POP). The goal was to access specific molecular information at the individual particle level in order to identify polymer debris in the natural environment. The identification process was aided by a laboratory generated automated fluorescence removal algorithm. Pacific Ocean trawl samples of plastic debris associated with fish collection sites were analyzed to determine the types of polymers commonly present...

In mammalian organisms liquid tumors such as acute myeloid leukemia (AML) are related to spontaneous chromosomal translocations ensuing in gene fusions. We previously developed a system named bridge-induced translocation (BIT) that allows linking together two different chromosomes exploiting the strong endogenous homologous recombination system of the yeast Saccharomyces cerevisiae. The BIT system generates a heterogeneous population of cells with different aneuploidies and severe aberrant phenotypes reminiscent of a cancerogenic transformation...

The compositions of in-host microbial communities (microbiota) play a significant role in host health, and a better understanding of the microbiota's role in a host's transition from health to disease or vice versa could lead to novel medical treatments. One of the first steps toward this understanding is modeling interaction dynamics of the microbiota, which can be exceedingly challenging given the complexity of the dynamics and difficulties in collecting sufficient data. Methods such as principal differential analysis, dynamic flux estimation, and others have been developed to overcome these challenges...

We detect objects more readily if they differ from their surroundings in motion, color, or texture. This increased saliency is thought to be related to increased responses in the visual cortex. The superior colliculus is another brain area involved in vision and especially in directing gaze and attention. In this study, we show that differences in texture orientation also increase responses in the superficial layers of the superior colliculus that receive retinal and cortical input. We found that gratings evoke more neural response when surrounded by orthogonal gratings than when surrounded by parallel gratings, particularly in the awake mouse...

Image-based salient object detection (SOD) has been extensively studied in past decades. However, video-based SOD is much less explored due to the lack of large-scale video datasets within which salient objects are unambiguously defined and annotated. Toward this end, this paper proposes a video-based SOD dataset that consists of 200 videos. In constructing the dataset, we manually annotate all objects and regions over 7,650 uniformly sampled keyframes and collect the eye-tracking data of 23 subjects who free-view all videos...
