BACKGROUND: Systemic administrations of conventional antithrombotics reduce neointima formation after angioplasty in experimental animals. However, clinical translation of these results has not been successful due to high risk for bleeding. OBJECTIVES: We sought to determine whether novel annexin-V (ANV)-Kunitz protease inhibitor fusion proteins, TAP-ANV and ANV-6L15, can specifically target to vascular injury site and limit neointima formation without inducing systemic hypo-coagulation in a rat carotid artery balloon angioplasty injury model...

Taking advantages of both the oxidation property of hypochlorite and different coordination properties of Cu(+) and Cu(2+) ions, we developed a new fluorescent probe for hypochlorite anion, namely, compound C1. In the presence of ClO(-), the sensing system displayed extraordinary fluorescence quenching, which was beneficial to the production of a high signal output during detection process. By virtue of its special oxidation property, the probe displayed high selectivity for ClO(-) over other anions. Moreover, this novel sensing system could be used for the analysis of ClO(-) levels in tap water and potentially in environmental samples...

Deficit in planning and problem-solving, affecting a wide range of neuropsychological patients, has been widely investigated using the Tower of London (ToL) test, as developed by Shallice (Philos Trans R Soc Lond Ser B Biol Sci 298:199-209, 1). The ToL taps on several executive functions (EF), such as planning, time for planning or rule breaks, which may be usefully indexed by different ToL measurements. However, in its original version, the different aspects involved in ToL are not evaluated in a specific way...

Creatine kinase isoform CK-MB has been widely applied as a biomarker of myocardial injury. While a variety of methods have been used to measure CK-MB activity or mass in clinical laboratories, a CK-MB standard is needed to eliminate between-method bias. Because the in vitro expression of human creatine kinase generates three isoenzymes, CK-MM, CK-MB, and CK-BB, it is important to establish an effective method to purify the isoform CK-MB from the mixture. In this study, we aimed at using tandem affinity purification (TAP) to purify recombinant CK-MB protein and evaluate its value in clinical laboratories...

The contrast sensitivity function (CSF) relates the visibility of a spatial pattern to both its size and contrast, and is therefore a more comprehensive assessment of visual function than acuity, which only determines the smallest resolvable pattern size. Because of the additional dimension of contrast, estimating the CSF can be more time-consuming. Here, we compare two methods for rapid assessment of the CSF that were implemented on a tablet device. For a single-trial assessment, we asked 63 myopes and 38 emmetropes to tap the peak of a "sweep grating" on the tablet's touch screen...

Finger pointing is a natural human behavior frequently used to draw attention to specific parts of sensory input. Since this pointing behavior is likely preceded and/or accompanied by the deployment of attention by the pointing person, we hypothesize that pointing can be used as a natural means of providing self-reports of attention and, in the case of visual input, visual salience. We here introduce a new method for assessing attentional choice by asking subjects to point to and tap the first place they look at on an image appearing on an electronic tablet screen...

Latinos consume more sugary drinks and less water than other demographic groups. Our objective was to understand beverage choice motivations and test promotional concepts that can encourage Central American Latino urban youth to drink more water. Two rounds of focus group discussions were conducted (n = 10 focus groups, 61 participants, 6-18 years old). Data were transcribed verbatim and analyzed using inductive and deductive coding approaches. Youth motivations for drinking water were shaped by level of thirst, weather, energy, and perceptions of health benefits...

Developmental dyslexia is a lifelong impairment affecting 5% to 10% of the population. In French-speaking countries, although a number of standardized tests for dyslexia in children are available, tools suitable to screen for dyslexia in adults are lacking. In this study, we administered the Alouette reading test to a normative sample of 164 French university students without dyslexia and a validation sample of 83 students with dyslexia. The Alouette reading test is designed to screen for dyslexia in children, since it taps skills that are typically deficient in dyslexia (i...

The goal of disinfection in the dental office is to prevent the spread of infection from one patient to another and maintain the safety of the dental care providers. Prevention of cross infection has significant effect on infection control. The standard procedure of rinsing impressions under tap water immediately after removal from the mouth eliminates microorganisms along with saliva and blood. A broad search on published literature was done using the keywords impression materials, disinfection method, and sterilization of dental impression from 1980 to 2016 in Medline, Google Scholar, the internet, and textbooks...

HPLC method was developed for the selective determination of phenazopyridine hydrochloride (PAP) in the presence of itscomputationally selected metabolite. Density functional theory was applied as a computational model to study the energy of PAP metabolites, and the results revealed that 2,3,6-triaminopyridine (TAP) is the most stable metabolite. Good resolution and separation of PAP from TAP was achieved using a reversed-phase BDS Hypersil C18 column with a mobile phase consisting of acetonitrile–water (75 + 25, v/v) at flow rate of 1 mL/min and with UV detection at 280 nm...

Perennial crops are vital contributors to global food production and nutrition. However, the breeding of new perennial crops is an expensive and time-consuming process due to the large size and lengthy juvenile phase of many species. Genomics provides a valuable tool for improving the efficiency of breeding by allowing progeny possessing a trait of interest to be selected at the seed or seedling stage through marker-assisted selection (MAS). The benefits of MAS to a breeder are greatest when the targeted species takes a long time to reach maturity and is expensive to grow and maintain...

The human nervous system is a vast network carrying not only sensory and movement information, but also information to and from our organs, intimately linking it to our overall health. Scientists and engineers have been working for decades to tap into this network and 'crack the neural code' by decoding neural signals and learning how to 'speak' the language of the nervous system. Progress has been made in developing neural decoding methods to decipher brain activity and bioelectronic technologies to treat rheumatoid arthritis, paralysis, epilepsy and for diagnosing brain-related diseases such as Parkinson's and Alzheimer's disease...

In this paper, an innovative and facile one-pot method for synthesizing water-soluble and stable fluorescent Cu nanoclusters (CuNCs), in which glutathione (GSH) served as protecting ligand and ascorbic acid (AA) as reducing agent was reported. The resultant CuNCs emitted blue-green fluorescence at 440 nm, with a quantum yield (QD) of about 3.08%. In addition, the prepared CuNCs exhibited excellent properties such as good water solubility, photostability and high stability toward high ionic strength. On the basis of the selective quenching of Hg(2+) on CuNCs fluorescence, which may be the result of Hg(2+) ion-induced aggregation of the CuNCs, the CuNCs was used for the selective and sensitive determination of Hg(2+) in aqueous solution...
