A relatively recent technique termed Comprehensive Multiphase (CMP) NMR spectroscopy was used to study the growth and associated metabolomic changes of 13C-labeled wheat seeds and germinated seedlings. CMP-NMR enables the study of all phases in intact samples: liquid, gel-like, semi-solid and solid, by combining all required electronics into a single NMR probe and can be used for investigating biological processes such as seed germination. All components, from the most liquid like (i.e. dissolved metabolites) to the most rigid or solid like (seed coat) were monitored in-situ over 4 days...

OBJECTIVES: We propose an architecture for monitoring outpatients that relies on mobile technologies for acquiring data. The goal is to better control the onset of possible side effects between the scheduled visits at the clinic. METHODS: We analyze the architectural components required to ensure a high level of abstraction from data. Clinical practice guidelines were formalized with Alium, an authoring tool based on the PROforma language, using SNOMED-CT as a terminology standard...

Online and mobile mental health applications (apps) herald exciting new opportunities for the treatment and prevention of self-injurious thoughts and behaviors (SITBs). With such rapid technological advances, it is paramount that health care innovation not be achieved to the detriment of intervention quality. Franklin et al.'s (2016) therapeutic evaluative conditioning (TEC) app is a novel and timely addition to the mobile health landscape; uncommonly for such apps, it is evidence based. There are, however, several crucial challenges to be surmounted for TEC to be successful; arguably, interventions ought to build lasting skills that can be subsequently and consciously recruited to manage distress beyond the intervention period...

Although transparent conducting oxides (TCOs) have played a key role in a wide range of solid-state electronics from conventional optoelectronics to emerging electronic systems, the processing temperature and conductivity of solution-processed materials seem to be far exceeding the thermal limitations of soft materials and insufficient for high-perfomance large-area systems, respectively. Here, we report a strategy to form highly conductive and scalable solution-processed oxide materials and their successful translation into large-area electronic applications, which is enabled by photo-assisted post-functionalization at low-temperature...

BACKGROUND: Approximately 11,000 people die in Scotland each year as a result of smoking-related causes. Quitting smoking is relatively easy; maintaining a quit attempt is a very difficult task with success rates for unaided quit attempts stubbornly remaining in the single digits. Pharmaceutical treatment can improve these rates by lowering the overall reward factor of nicotine. However, these and related nicotine replacement therapies do not operate on, or address, the spatial and contextual aspects of smoking behaviour...

A pulpectomy requires the swift extraction of the inflamed tissue. Moreover, the speed of treatment is especially important in the case of uncooperative children. Conventional pulpectomies, however, often require an extended treatment period, which can therefore cause problems with such patients. Electrosurgical methods have been applied to pulpotomies for a number of years. However, to the best of our knowledge, no studies to date have assessed its application to pulpectomies. The aim of this study was to compare clinical and radiographic success rates over a 6-month follow-up period between conventional and electrosurgical pulpectomies...

Electrokinetic (EK) remediation can be a suitable technology for treating contaminated dredged harbor sediment, stored on terrestrial disposal sites. Citric acid (CA) and biosurfactants (rhamnolipids and saponin) were chosen as enhancing agents for simultaneous metal (Cd, Cr, Cu, Pb, Zn) and PAH/PCB removal by EK because of their potential low toxicity with a view to site restoration. Three EK runs were performed using a periodic voltage (1Vcm(-1)) and various concentrations of agents. The best combination of CA (0...

In modeling solute transport with mobile-immobile mass transfer (MIMT), it is common to use an advection-dispersion equation (ADE) with a retardation factor, or retarded ADE. This is commonly referred to as making the local equilibrium assumption (LEA). Assuming local equilibrium, Eulerian textbook treatments derive the retarded ADE, ostensibly exactly. However, other authors have presented rigorous mathematical derivations of the dispersive effect of MIMT, applicable even in the case of arbitrarily fast mass transfer...

Synthetic organic nanotubes self-assembled from bolaamphiphile surfactants are now being explored for use as drug delivery vehicles. In this work, several factors important to their implementation in drug delivery are explored. All experiments are performed with the nanotubes immersed in ethanol. First, Nile Red (NR) and a hydroxylated Nile Red derivative (NR-OH) are loaded into the nanotubes and spectroscopic fluorescence imaging methods are used to determine the apparent dielectric constant of their local environment...

The recent exploration of semiconducting two-dimensional (2D) transition metal dichalcogenides (TMDs) with atomic thickness has taken both the scientific and technological communities by storm. Extensively investigated TMD that are accessible by large-scale synthetic methods materials are remarkably stable, such as MoS2 and WSe2 . They allow superior gate control due to their 2D nature and favorable electronic transport properties, thus suggesting a bright future for digital and RF electronics. In this review, the latest developments in the controlled synthesis of large scale TMDs are firstly introduced by discussing various approaches...

The Liver X Receptors (LXRs) are oxysterol-activated transcription factors that upregulate a suite of genes that together promote coordinated mobilization of excess cholesterol from cells and from the body. The LXRs, like other nuclear receptors, are anti-inflammatory, inhibiting signal-dependent induction of pro-inflammatory genes by nuclear factor-κB, activating protein-1, and other transcription factors. Synthetic LXR agonists have been shown to ameliorate atherosclerosis and a wide range of inflammatory disorders in preclinical animal models...

Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored. Recently, studies on a few model archaeal viruses such as SIRV2 (Sulfolobus islandicus rod-shaped virus) have revealed an unusual lysis mechanism that involves the formation of pyramidal egress structures on the host cell surface. To expand understanding of the infection cycle of SIRV2, we aimed to functionally characterize gp1, which is a SIRV2 gene with unknown function...

In this paper, high performance top-gated WSe2 field effect transistor (FET) devices are demonstrated via a two-step remote plasma assisted ALD process. High-quality, low-leakage aluminum oxide (Al2O3) gate dielectric layers are deposited onto the WSe2 channel using a remote plasma assisted ALD process with an ultrathin (~1 nm) titanium buffer layer. The first few nanometers (~2 nm) of the Al2O3 dielectric film is deposited at relatively low temperature (i.e. 50 ºC) and remainder of the film is deposited at 150 ºC to ensure the conformal coating of Al2O3 on the WSe2 surface...

Plant hormones are important mobile endogenous signaling molecules that regulate responses to abiotic stress as well as plant growth and development. Visual information on more than one plant hormone from the same sample would be especially powerful, because it could enable rapid, intuitive interpretation. However, multi-imaging techniques for plant hormones have been unavailable. Here, we report the first multi-imaging of two plant hormones, one of cytokinin (i.e. trans-zeatin) and abscisic acid (ABA) by MALDI-TOF-MS imaging...

PURPOSE: Almost nine of 10 deaths resulting from cervical cancer occur in low-income countries. Visual inspection under acetic acid (VIA) is an evidence-based, cost-effective approach to cervical cancer screening (CCS), but challenges to effective implementation include health provider training costs, provider turnover, and skills retention. We hypothesized that a smartphone camera and use of cervical image transfer for real-time mentorship by experts located distantly across a closed user group through a commercially available smartphone application would be both feasible and effective in enhancing VIA skills among CCS providers in Tanzania...

Vaccination is one of the main tools currently available to control animal diseases. In eradication campaigns, vaccination plays a crucial role by reducing the number of susceptible hosts with the ultimate goal of interrupting disease transmission. Nevertheless, mass vaccination campaigns may be very expensive and in some cases unprofitable. VacciCost is a tool designed to help decision-makers in the estimation of the resources required to implement mass livestock vaccination campaigns against regulated diseases...

Sexting, defined as the sending and receiving of sexually suggestive or sexually explicit text or photos, has been growing in prevalence. Recent studies have demonstrated that over half of individuals sampled over 17 and regardless of gender participate in some type of sexting behavior. Most studies on sexting behaviors, including those looking at men who have sex with men (MSM) focus on emerging adult or university-based populations. The goal of the current study was to sample a nonuniversity-based MSM adult population to determine the prevalence of sexting behavior and the odds that a person engages in sexting behaviors based on certain sexual behaviors...
