This work presents a portable electrochemical system for the continuous monitoring of corrosion inhibitors in a wide range of matrices including ethanol, seawater and mineral oil following simple dilution of the samples. Proof-of-concept is demonstrated for the sensing of 2,5-dimercapto-1,3,5-thiadiazole (DMCT), an important corrosion inhibitor. Disposable screen-printed graphitic electrodes (SPGEs) associated with a portable batch-injection cell are proposed for the amperometric determination of DMCT following sample dilution with electrolyte (95% v/v ethanol + 5% v/v 0...

BACKGROUND AND OBJECTIVE: Teucrium polium Lamiaceae. an antidiabetic traditional medicine was observed to stimulate insulin secretion and β-cell mass restoration in pancreatic of diabetic rats. Bioactive compounds in T. polium such as terpenoids and flavonoids have a wide range of antioxidant properties. Given this background, our research was aimed at probing the effective molecular mechanism of T. polium which in turn protects the pancreatic β-cells of diabetic rats through attenuation of streptozotocin-induced oxidative stress...

BACKGROUND: Arteriovenous (AV) loops can be utilized in a single- or two-stage approach in free flap reconstruction when proper vessels are not available. However, there exists no consensus on which method leads to superior microsurgical and patient outcomes. The purpose of this article was to review single- versus two-stage AV loops utilized in free flap reconstruction with a focus on complications and overall outcomes. METHODS: A systematic review of AV loops for autologous free tissue transfer was conducted...

BACKGROUND: We evaluated cognitive function and factors associated with cognitive impairment in a cohort of older homeless adults. We hypothesized that substance use and a history of traumatic brain injury would be associated with cognitive impairment. METHODS: We recruited 350 homeless individuals aged ≥50 years using population-based sampling and conducted structured interviews and neuropsychological testing. We evaluated alcohol use with the Alcohol Use Disorder Identification Test, defining high-severity alcohol use as a total score ≥16 or ≥4 on the alcohol dependency sub-scale...

Children with cerebral palsy (CP) are often mainstreamed into the general education system, but are likely to be excluded from physical education (PE) classes. A questionnaire was constructed and utilized to measure PE teachers' self-efficacy (SE) toward inclusion of students with CP in each of three mobility categories (independent, using assistive devices, using wheelchair mobility) and the impact of experience and training on teachers' SE. Participants in the study were 121 PE teachers from different parts of Israel (mean age: 41...

Non-suicidal self-harm includes cutting, scratching, burning and minor overdosing. There have been few studies that have examined the rate and pattern of self-harm among different individuals of the society. We performed a population-based study to determine different aspects of non-suicidal self-harm in cases referred to legal medicine organization of Fars Province and south Iran. In a population-based longitudinal survey, we applied data from cases referred to legal medicine organization of Fars province...

Perovskite material with a bandgap of 1.7 eV - 1.8 eV is highly desirable for the top cell in a tandem configuration with a lower bandgap bottom cell, such as a silicon cell. This can be achieved by alloying iodide and bromide anions, but light-induced phase segregation phenomena is often observed in perovskite films of this kind, with implications for solar cell efficiency. Here we investigate light-induced phase segregation inside quadruple cation perovskite material in a complete cell structure, and find that the magnitude of this phenomenon is dependent on the operating condition of the solar cell...

Understanding the modulation of the electronic coupling in donor-acceptor systems connected through an aliphatic bridge is crucial from a fundamental point of view as well as for the development of organic electronics. In this work, we present a first-principles approach for the calculation of the electronic coupling (or transfer integrals) in such systems via a block-diagonalization of the Fock/Kohn-Sham matrix of the supersystem, followed by a projection on the basis of the fragment orbitals of the donor and acceptor groups...

AIMS: To evaluate and compare the effectiveness of two concentrations of topical clonazepam solution in improving symptoms of burning mouth syndrome (BMS). METHODS: A retrospective chart review was conducted of patients diagnosed with BMS and managed with topical clonazepam solution between 2008 and 2015. A 0.5-mg/mL solution was prescribed until 2012, when this was changed to a 0.1 mg/mL solution. Patients were instructed to swish with 5 mL for 5 minutes and spit two to four times daily...

AIMS: To propose a visual method to screen and assess psychosocial functioning in temporomandibular disorder (TMD) pain patients in comparison with age- and gender-matched healthy controls by forming individual profiles and to evaluate the association between psychosocial profiles and quantitative sensory testing (QST) findings of TMD pain patients. METHODS: TMD patients (n = 58) and control participants (n = 41) completed a set of questionnaires profiling their psychosocial function, and QST was performed at the temporomandibular joint (TMJ) on both sides of the face in all participants...

BACKGROUND: Although gambling disorder is prevalent and functionally impairing, no FDA-approved medications exist for its treatment. The ability of clinical trials to detect the benefits of active treatment has been hindered by an unusually high placebo response. Virtually nothing is known about baseline clinical characteristics that might predict placebo response in those with gambling disorder. METHODS: Participants (N = 152) assigned to placebo were pooled from multiple double-blind trials of gambling disorder...

BACKGROUND: A notable variation among patient satisfaction scores with nursing care was identified. Contributing factors were examined and revealed significant negative correlations between the unit death rate and surviving patients' satisfaction scores. Compassion fatigue (CF) was hypothesized to be a major contributing factor.

BACKGROUND: AbbVie provides a free-to-patient patient support program (PSP) to assist adalimumab-treated patients with medication costs, nurse support, injection training, pen disposal, and medication reminders. The impact of these services on patient adherence to adalimumab and direct medical costs associated with autoimmune disease has not been assessed. OBJECTIVE: To quantify the relationship between participation in a PSP and outcomes (adalimumab adherence, persistence, and direct medical costs) in patients initiating adalimumab treatment...

At the ASCO Data Standards and Interoperability Summit held in May 2016, it was unanimously decided that four areas of current oncology clinical practice have serious, unmet health information technology needs. The following areas of need were identified: 1) omics and precision oncology, 2) advancing interoperability, 3) patient engagement, and 4) value-based oncology. To begin to address these issues, ASCO convened two complementary workshops: the Omics and Precision Oncology Workshop in October 2016 and the Advancing Interoperability Workshop in December 2016...

The objective of this study was to evaluate the effect of anxiety-reducing techniques including music therapy, sophrology, and creative visualization in pregnant women with a fetus diagnosed as small for gestational age and improved fetal and neonatal weight. This was a quasi-experimental study with a nonrandomized clinical trial design. We compared 2 groups of pregnant women with a fetus diagnosed as small for gestational age with no abnormalities on Doppler studies. The control group (n = 93) received standard care, and the intervention group (n = 65), in addition to standard care, underwent a program of 6 sessions led by a midwife or nurse who taught anxiety-reduction techniques...

Adoptive transfer of T cells engineered to express a hepatitis B virus-specific (HBV-specific) T cell receptor (TCR) may supplement HBV-specific immune responses in chronic HBV patients and facilitate HBV control. However, the risk of triggering unrestrained proliferation of permanently engineered T cells raises safety concerns that have hampered testing of this approach in patients. The aim of the present study was to generate T cells that transiently express HBV-specific TCRs using mRNA electroporation and to assess their antiviral and pathogenetic activity in vitro and in HBV-infected human liver chimeric mice...
