Various fluorescent sensing systems for miRNAs detection have been developed. But they mostly contain enzymatic amplification reactions and label procedures. The strict reaction conditions of tool enzymes and the high cost of labeling limit their potential applications, especially in complex biological matrix. Here we have addressed the difficult problems and report a strategy for label-free fluorescent DNA dendrimers based on enzyme-free nonlinear hybridization chain reaction (HCR)-mediated multiple G-quadruplex for simple, sensitive and selective detection of miRNAs with low-background signal...

Intimate partner communication has become a part of the daily routine of military couples during deployment. However, there is a scarcity of research examining the individual and relationship implications of communication during deployment, likely due in part to the lack of existing measures of deployment communication. The current study examined the psychometric characteristics of a newly developed, multidimensional tool for assessing the process and outcomes of deployment communication in a sample of 391 recently deployed male Army National Guard soldiers and their female intimate partners...

Background: Microalgae accumulate lipids when exposed to stressful conditions such as nutrient limitation that can be used to generate biofuels. Nitrogen limitation or deprivation is a strategy widely employed to elicit this response. However, this strategy is associated with a reduction in the microalgal growth, leading to overall poor lipid productivities. Here, we investigated the combined effect of a reduced source of nitrogen (ammonium) and super-saturating light intensities on the growth and induction of lipid accumulation in two model but diverse microalgal species, Phaeodactylum tricornutum and Nannochloropsis oceanica ...

Background: Human resources are consistently cited as a leading contributor to health care costs; however the availability of internationally comparable data on health worker earnings for all countries is a challenge for estimating the costs of health care services. This paper describes an econometric model using cross sectional earnings data from the International Labour Organization (ILO) that the World Health Organizations (WHO)-Choosing Interventions that are Cost-effective programme (CHOICE) has used to prepare estimates of health worker earnings (in 2010 USD) for all WHO member states...

A method for the production of liquid capsules with the potential of modifying drug dose and release is presented. For the first time, the co-ordinated use of fused deposition modelling (FDM), 3D printing and liquid dispensing to fabricate individualised dosage form on demand in a fully automated fashion has been demonstrated. Polymethacrylate shells (Eudragit EPO and RL) for immediate and extended release were fabricated using FDM 3D printing and simultaneously filled using a computer-controlled liquid dispenser loaded with model drug solution (theophylline) or suspension (dipyridamole)...

We report a Ni30Pd70/nitrogen-doped graphene (NG) catalyst that hydrodehalogenates halogenated aromatics under mild reaction conditions. It reduces mono- or dichloroarenes to the corresponding dehalogenated arenes in >90% yield in 10% aqueous isopropanol solvent at or below 50C within 5 hours. Tests on a variety of substrates containing various functional groups show that the catalyst is selective for reduction of C-Cl and C-Br bonds. In addition, this catalyst completely hydrodehalogenates high concentration solutions of dioxin, polychlorinated biphenyls (PCBs), chloroaromatic constituents of the defoliant agent orange, and polybrominated diphenyl ethers (PBDEs) in 12 hours...

The objective of this study was to assess the impact of diverse plasmids bearing colistin resistance gene mcr-1 on host fitness. Forty-seven commensal E. coli isolates recovered from the pig farm where mcr-1 was first identified were screened for mcr-1. mcr-1 -bearing plasmids were characterized by sequencing. The fitness impact of mcr-1 -bearing plasmids was evaluated by in vitro competition assays. Twenty-seven (57.5%) E. coli isolates were positive for mcr-1 . The mcr-1 genes were mainly located on plasmids belonging to IncI2 ( n = 5), IncX4 ( n = 11), IncHI2/ST3 ( n = 8), IncFII ( n = 2), and IncY ( n = 2)...

Countercurrent chromatography (CCC) has gradually become a widely used method for preparative separation of bioactive natural molecules. These molecules generally contain distinct scaffolds and characteristics that cannot be readily isolated from plants. While one-dimensional CCC is typically used for the initial purification with insufficiently resolved peaks after locating bioactive components, two-dimensional (2D) or multi-dimensional CCC strategies are employed to improve the resolution of peaks. However, these methods usually present certain disadvantages, such as complicated procedures and increased time consumption, experimental costs, and equipment requirements...

A safe potassium rechargeable battery of high energy density and excellent cycling stability is demonstrated. The cell contained a polyaniline cathode into which the anion component of the electrolyte salt is inserted on charge, extracted on discharge; but the K+ ion of a KPF6 salt is plated/stripped on the potassium-metal anode. The use of a p-type polymer cathode increases the cell voltage. By replacing the organic-liquid electrolyte in a glass-fiber separator by a polymer-gel electrolyte of cross-linked poly(methyl methacrylate), a dendrite-free potassium anode can be plated/stripped and the electrode/electrolyte interface stabilized...

Recent technological advances in radiation therapy have allowed for greater accuracy in planning and treatment delivery. The development of hypofractionated radiation treatment regimens is an example, and has the potential to decrease the cost per episode of care, relative to conventional treatments. Our aim was to analyse published literature on the cost-effectiveness and budgetary implications of hypofractionated radiation therapy. As such, this article will quantify the projected health care cost savings and address the optimal means of treatment delivery, associated patient outcomes, and implications arising from an increased use of hypofractionated regimens...

BACKGROUND: The National Health Service (NHS) in England spends over £9 billion on prescription medicines dispensed in primary care, of which over two-thirds is accounted for by repeat prescriptions. Recently, GPs in England have been urged to limit the duration of repeat prescriptions, where clinically appropriate, to 28 days to reduce wastage and hence contain costs. However, shorter prescriptions will increase transaction costs and thus may not be cost saving. Furthermore, there is evidence to suggest that shorter prescriptions are associated with lower adherence, which would be expected to lead to lower clinical benefit...

A novel magnetic bio-adsorbent (MCIA) was developed, characterized and tested for its Cd(II) removal from aqueous solution. MCIA could be easily separated from the solution after equilibrium adsorption due to its super-paramagnetic property. The functional and magnetic bio-material was an attractive adsorbent for the removal of Cd(II) from aqueous solution owing to the abundant adsorption sites, amino-group and oxygen-containing groups on the surface of Cyclosorus interruptus. The experimental results indicated that the MCIA exhibited excellent adsorption ability and the adsorption process was spontaneous and endothermic...
