The effects of an afterschool STEM program on students’ motivation and engagement
(2017-06-12)
Background: One significant factor in facilitating students’ career intentions and persistence in STEM (science, technology, engineering, and mathematics) fields is targeting their interests and motivation before eighth ...
A high-efficiency CRISPR/Cas9 system for targeted mutagenesis in Cotton (Gossypium hirsutum L.)
(2017-03-03)
The complex allotetraploid genome is one of major challenges in cotton for repressing gene expression.
Developing site-specific DNA mutation is the long-term dream for cotton breeding scientists. The
clustered regularly ...
Clinical Outcomes by Race and Ethnicity in the Systolic Blood Pressure Intervention Trial (SPRINT): A Randomized Clinical Trial
(2017-08-23)
BACKGROUND:
The Systolic Blood Pressure Intervention Trial (SPRINT) showed that targeting a systolic blood pressure (SBP) of ≤ 120 mm Hg (intensive treatment) reduced cardiovascular disease (CVD) events compared to SBP ...
It’s not what you expect: feedback negativity is independent of reward expectation and affective responsivity in a non-probabilistic task
(2017-03)
ERP studies commonly utilize gambling-based reinforcement tasks to elicit feedback negativity (FN) responses. This study used a pattern learning task in order to limit gambling-related fallacious reasoning and possible ...
Impaired contractile function of the supraspinatus in the acute period following a rotator cuff tear
(2017-11-09)
Background: Rotator cuff (RTC) tears are a common clinical problem resulting in adverse changes to the muscle, but there is limited information comparing histopathology to contractile function. This study assessed supraspinatus ...
Fractional Flow Reserve/ Instantaneous Wave-Free Ratio Discordance in Angiographically Intermediate Coronary Stenoses: An Analysis Using Doppler-Derived Coronary Flow Measurements
(2017-12-26)
OBJECTIVES The study sought to determine the coronary flow characteristics of angiographically intermediate stenoses classified as discordant by fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR).
BACKGROUND ...
MicroRNA expression profiles during cotton (Gossypium hirsutum L) fiber early development
(2017-03-22)
The role of microRNAs (miRNAs) during cotton fiber development remains unclear. Here, a total of
54 miRNAs belonging to 39 families were selected to characterize miRNA regulatory mechanism in eight different fiber development ...
Karyotype analysis and sex determination in Australian Brush-turkeys (Alectura lathami)
(2017-09-14)
Sexual differentiation across taxa may be due to genetic sex determination (GSD) and/or temperature sex determination (TSD). In many mammals, males are heterogametic (XY); whereas females are homogametic (XX). In most ...
Limited indications of tax stamp discordance and counterfeiting on cigarette packs purchased in tobacco retailers, 97 counties, USA, 2012
(2017-09-28)
Increasing the per-unit cost of tobacco products is one of the strongest interventions for tobacco control. In jurisdictions with higher taxes in the U.S., however, cigarette pack litter studies show a substantial proportion ...
