A positive urine pregnancy test (UPT) with adnexal mass in ectopic pregnancy is not the ultimate diagnosis. The incidence of ectopic pregnancy is about 27 per 1000 pregnancies [1]. On average, about 6-16% will present to an emergency department with first-trimester bleeding and abdominal pain [2]. On presenting with these symptoms with the simultaneous presence of an adnexal mass and an empty uterus, a UPT is of paramount importance to determine whether the symptoms are pregnancy related or not. When the UPT is positive, an ectopic pregnancy is not the only diagnosis as the rare entity of non-gestational ovarian choriocarcinoma (NGOC) should be considered...

Atherosclerosis is an inflammatory disease of arterial walls and the rupturing of atherosclerotic plaques is a major cause of heart attack and stroke. Imaging techniques that can enable the detection of atherosclerosis plaques before clinical manifestation are urgently needed. Magnetic resonance imaging (MRI) is a powerful technique to image the morphology of atherosclerotic plaques. In order to better analyze molecular processes in plaques, contrast agents that can selectively bind to plaque receptors will prove invaluable...

The presence of myocardial ischemia is the most important prognostic factor in patients with coronary artery disease, and ischemia-directed revascularization has been a standard of care. Fractional flow reserve (FFR) is an invasive method used to detect the functionally significant epicardial coronary stenosis, and FFR-guided revascularization strategy has been proven to be superior to angiography-guided strategy. Recently, a hyperemia-free index, instantaneous wave free ratio (iFR), was developed and showed its non-inferiority for clinical outcomes compared with FFR-guided strategy...

The Siberian larch forests, taking up about a fifth of the global boreal biome, are different from the North American boreal forests in that they generally do not undergo a secondary succession. While wildfires in the boreal forests in North America have been shown to exert a cooling effect on the climate system through a sharp increase in surface albedo associated with canopy removal and species composition change during succession, the magnitude of the surface forcing resulting from fire-induced albedo change and its longevity in Siberia have not been previously quantified...

I argue for a full mathematization of the physical theory, including its axioms, which must contain no physical primitives. In provocative words: 'physics from no physics'. Although this may seem an oxymoron, it is the royal road to keep complete logical coherence, hence falsifiability of the theory. For such a purely mathematical theory the physical connotation must pertain only the interpretation of the mathematics, ranging from the axioms to the final theorems. On the contrary, the postulates of the two current major physical theories either do not have physical interpretation (as for von Neumann's axioms for quantum theory), or contain physical primitives as 'clock', 'rigid rod', 'force', 'inertial mass' (as for special relativity and mechanics)...

Calcineurin is a phosphatase that targets the transcription factor, nuclear factor of activated T-cells (NFAT) dephosphorylates multiple sites along NFAT's regulatory domain. The calcineurin-NFAT complex interaction is mediated through two conserved binding motifs known as the PxIxIT and LxVP, which are located at the N- and C- terminus to the phosphorylation sites. The vast range of cellular processes regulated by the calcineurin-NFAT interaction has aroused great interest in the investigation of the structural aspects that govern their complex formation and in the discovery of protein-protein interaction inhibitors; the latter interfere with calcineurin-NFAT complex formation while keeping calcineurin's catalytic site free...

Venous congestion results in tissue damage and remains the most common reason for failure of transfer of microvascular free flaps if it is not recognised early. The purpose of this study was to measure the critical duration of venous congestion and the resultant survival of flaps according to the duration of venous stasis. A standard epigastric flap was raised and repositioned in 35 rats, seven of which acted as controls. The superficial inferior epigastric vein was fully occluded for four, five, six, or seven hours in the rest (n=7 each group)...

Bleomycin (BLM) is an antibiotic isolated from Streptomyces verticillus. It has radiomimetic actions on DNA thus it has been widely used in clinical chemotherapy for the treatment of different types of cancer, including head and neck tumors, lymphomas, squamous-cell carcinomas and germ-cell tumors. Because of this, the study of BLM genotoxicity is of practical interest. This antibiotic is an S-independent clastogen and an agent that generates free radicals and induces single- and double-strand breaks in DNA...

Self-assembled DNA structures enable creation of specific shapes at the nm-µm scale with molecular resolution. The creation of functional DNA assemblies will likely require dynamic structures that can undergo controllable conformational changes. DNA devices based on shape complementary stacking interactions have been demonstrated to undergo reversible conformational changes triggered by changes in ionic environment or temperature. An experimentally unexplored aspect is how quickly conformational transitions of large synthetic DNA origami structures can actually occur...

Four experiments supported the hypothesis that ordinary people understand free will as meaning unconstrained choice, not having a soul. People consistently rated free will as being high unless reduced by internal constraints (i.e., things that impaired people's mental abilities to make choices) or external constraints (i.e., situations that hampered people's abilities to choose and act as they desired). Scientific paradigms that have been argued to disprove free will were seen as reducing, but usually not eliminating free will, and the reductions were because of constrained conscious choice...

BACKGROUND: Muscle flap is a valuable option in soft tissue reconstruction. Denervated skeletal muscle is known to undergo degeneration. However, information regarding histological and genetic changes in muscle free flap without reinnervation over long-term follow-up remains unclear. METHODS: We collected flap muscles obtained during secondary exploration surgery after more than 15 years of previous muscle free flap without reinnervation. Compared with normal muscle and fat, histomorphometric and gene expression analysis of flap muscle were performed...

BACKGROUND: Relatively little evidence exists for type 2 diabetes mellitus (T2DM) prediction models from long-term follow-up studies in East Asians. This study aims to develop a point-based prediction model for 10-year risk of developing T2DM in middle-aged Japanese men. METHODS: We followed 3,540 male participants of Aichi Workers' Cohort Study, who were aged 35-64 years and were free of diabetes in 2002, until March 31, 2015. Baseline age, body mass index (BMI), smoking status, alcohol consumption, regular exercise, medication for dyslipidemia, diabetes family history, and blood levels of triglycerides (TG), high density lipoprotein cholesterol (HDLC) and fasting blood glucose (FBG) were examined using Cox proportional hazard model...

This paper investigates the impacts of smoke-free housing policies on compliance, enforcement and smoking behavior. From 2012 to 2014, we studied two affordable housing providers in Canada with comprehensive smoke-free policies: Waterloo Regional Housing that required new leases to be non-smoking and exempted existing leases, and Yukon Housing Corporation that required all leases (existing and new) to be non-smoking. Focus groups and key informant interviews were conducted with 31 housing and public health staff involved in policy development and implementation, and qualitative interviews with 56 tenants...

Label-free visualization of nerves and nervous plexuses will improve the preservation of neurological functions in nerve-sparing robot-assisted surgery. We have developed a coherent anti-Stokes Raman scattering (CARS) rigid endoscope to distinguish nerves from other tissues during surgery. The developed endoscope, which has a tube with a diameter of 12 mm and a length of 270 mm, achieved 0.91% image distortion and 8.6% non-uniformity of CARS intensity in the whole field of view (650 μm diameter). We demonstrated CARS imaging of a rat sciatic nerve and visualization of the fine structure of nerve fibers...

Prenylated flavin mononucleotide (prFMN) is a recently discovered cofactor required by the UbiD family of reversible decarboxylases involved in ubiquinone biosynthesis, biological decomposition of lignin, and biotransformation of aromatic compounds. This cofactor is synthesized by UbiX-like prenyltransferases catalyzing the transfer of the dimethylallyl moiety of dimethylallyl-monophosphate (DMAP) to FMN. The origin of DMAP for prFMN biosynthesis and the biochemical properties of free prFMN are unknown. We show that in Escherichia coli cells, DMAP can be produced by phosphorylating prenol using ThiM or dephosphorylating DMAPP using Nudix hydrolases...
