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...

BACKGROUND AND OBJECTIVES: Physicians must communicate effectively with patients. Actual patients (APs) rarely evaluate medical students' clinical skills; instead, standardized patients (SPs) provide proxy ratings. It is unclear how well SP ratings mirror AP experiences. The aim of this study was to compare AP and SP assessments of medical students' communication skills and professionalism. We hypothesized that their perspectives would be similar, but distinct, and offer insight about how to more reliably include the patient's voice in medical education...

Importance: More than half of all new melanoma diagnoses present as clinically localized T1 melanoma, yet sentinel lymph node biopsy (SLNB) is controversial in this population given the overall low yield. Guidelines for SLNB have focused on pathologic factors, but patient factors, such as age, are not routinely considered. Objectives: To identify indicators of lymph node (LN) metastasis in thin melanoma in a large, generalizable data set and to evaluate the association between patient age and LN positivity...

Every year, the production of coal-bed natural gas in the Powder River Basin results in the discharge of large amounts of coal-bed methane water (CBMW) in Wyoming; however, no sustainable disposal methods for CBMW are currently available. A greenhouse study was conducted to evaluate the potential to use CBMW as a source of irrigation water for camelina [ (L.) Crantz]. We assessed the effects of three CBMW concentrations (0% [1:0], 50% [1:1], and 100% [0:1] tap water to CBMW) on selected soil properties, growth, seed oil, and fatty acid composition of three camelina cultivars: Blaine Creek, Ligena, and Pronghorn...

Onsite wastewater treatment systems (OWTSs) can be a source of nitrogen (N) pollution in both surface and ground waters. In metropolitan Atlanta, GA, >26% of homes are on OWTSs. In a previous article, we used the Soil Water Assessment Tool to model the effect of OWTSs on stream flow in the Big Haynes Creek Watershed in metropolitan Atlanta. The objective of this study was to estimate the effect of OWTSs, including failing systems, on nitrate as N (NO-N) load in the same watershed. Big Haynes Creek has a drainage area of 44 km with mainly urban land use (67%), and most of the homes use OWTSs...

The water and sanitation sector is verifiably receiving increased attention and funding through international development cooperation. Not least because of the way that it affects incentives and institutions in partner countries, development cooperation can have either positive or negative effects on human rights though. The consolidated frameworks for the human rights to water and sanitation is becoming linked to the international community's coordinated development efforts, as evidenced notably in the 2030 Agenda for Sustainable Development...

The aim of this paper is twofold. First, it aims to investigate the increased interest in health as an important dimension of the foreign policy and diplomatic concerns together with the emergence of a new framework for regional health integration and regional health diplomacy. Second, it seeks to understand the role and practices of new regional blocs in the field of health and whether they are conducting to the emergence of new strategies for addressing health regional policies in South America. The regional policy process relates to health as a right...

The most common cause of the monogenic form of Parkinson's disease known so far is the G2019S mutation of the leucine-rich repeat kinase 2 (LRRK2) gene. Its frequency varies greatly among ethnic groups and geographic regions ranging from less than 0.1% in Asia to 40% in North Africa. This mutation has three distinct haplotypes; haplotype 1 being the oldest and most common. Recent studies have dated haplotype 1 of the G2019S mutation to about 4000 years ago, but it remains controversial whether the mutation has a Near-Eastern or Moroccan-Berber ancestral origin...

Sprint performance is an important characteristic for success in many sports, including rugby union. Resistance training is used to increase muscular fitness (i.e. strength, endurance and power) and may also be effective for improving sprint and jump performances. The aims of this study were to examine the effects of resistance training using two different periodized programs (linear and daily undulating) on sprint and jump performance and explore relationships between performance measures. Sixteen male (16...

OmpF porin from the outer membrane of Yersinia pseudotuberculosis was cloned into pET-40b(+) plasmid. Using E. coli Rosetta (DE3) strain, MX-medium, IPTG concentration of 0.2 mM and post-induction cultivation at 14 °C overnight allowed us to obtain a water-soluble form of the recombinant protein (rs-OmpF). Rs-OmpF was shown to have the ordered spatial structure at the levels of secondary and tertiary structure. Rs-OmpF was found to be effective as diagnostic antigen in ELISA for pseudotuberculosis diagnostics...

The development of CD1d-restricted invariant natural killer T (iNKT) cells, a population that is critical for both innate and adaptive immunity, is regulated by multiple transcription factors, but the molecular mechanisms underlying how the transcriptional activation of these factors are regulated during iNKT development remain largely unknown. We found that the histone acetyltransferase general control non-derepressible 5 (GCN5) is essential for iNKT cell development during the maturation stage. GCN5 deficiency blocked iNKT cell development in a cell-intrinsic manner...

BACKGROUND: Population data suggest that black men have a higher risk of dying from prostate cancer (PCa) than other racial ethnicities. OBJECTIVE: To examine the impact of black race on progression-free survival (PFS) and overall survival (OS) among men with metastatic castration-resistant PCa (mCRPC) enrolled in randomized controlled trials (RCTs). DESIGN, SETTING, AND PARTICIPANTS: A pooled analysis was performed on individual patient data from five modern PCa RCTs available from Project Data Sphere...

The NF-κB family of transcription factors is essential for an effective immune response, but also controls cell metabolism, proliferation and apoptosis. Its broad relevance and the high connectivity to diverse signaling pathways require a tight control of NF-κB activity. To investigate the control of NF-κB activity by phosphorylation of the NF-κB p65 subunit, we generated a knock-in mouse model in which serine 467 (the mouse homolog of human p65 serine 468) was replaced with a non-phosphorylatable alanine (S467A)...

OBJECTIVE: To review the use of outcome measures (OMs) and definitions of success in the literature on SUI and VD surgery in women in an attempt to provide recommendations for future publications. EVIDENCE ACQUISITION: A PubMed search of all English language full-text articles on SUI and VD surgery in women published between 2010 and 2015 was performed...

A label-free electrochemical impedance spectroscopy (EIS) aptasensor for rapid detection (<35 min) of interferon-gamma (IFN-γ) was fabricated by immobilizing a RNA aptamer capture probe (ACP), selective to IFN-γ, on a gold interdigitated electrode array (Au IDE). The ACP was modified with a thiol group at the 5' terminal end and subsequently co-immobilized with 1,6-hexanedithiol (HDT) and 6-mercapto-1-hexanolphosphate (MCH) to the gold surface through thiol-gold interactions. This ACP/HDT-MCH ternary surface monolayer facilitates efficient hybridization with IFN-γ and displays high resistance to nonspecific adsorption of nontarget proteins [i...

In this work, we demonstrate the quantification of creatinine in human urine samples using a microcalorimetric sensing system. The calorimetric sensor is based on an array of microfabricated Y-cut quartz resonators. The piezoelectric quartz is etched down to a thickness of 10 μm and exhibits a bulk acoustic resonance of 166 MHz. The temperature sensitivity of this high-frequency quartz resonator is 14 600 Hz/K due to the high phenomenological sensitivity of quartz. Most importantly, the quartz sensors and the analyte fluidics are decoupled providing a significantly more robust calorimetric sensing system than directly contacted chip calorimeters...
