Crucial to the spread of the octopus from tropics to poles is their ability to sustain oxygen supply even at sub-zero temperatures; molecular and structural evolution of the octopus blood-carrying molecule appears to be key to this.
In a Q-sort survey, tasks considered most important for peer reviewers of randomized controlled trials, were often not clearly indicated by editors, including evaluating the risk of bias, which was clearly requested by only 5% of journal editors.
An adjustable fetal weight standard for twin pregnancies can be used to accurately assess growth while taking into account variables such as race, suggesting that this tool can be used in different populations.
Randomized trials are not always the best way to ascertain the benefit of medical interventions; Milo Puhan and colleagues argue that quantitative benefit-herm assessments should be used to guide further research, discussing rofilumast as an example.
This study demonstrates that the relationship between appearance comparison and body image dissatisfaction is comparative for those exposed to Facebook images and those exposed to conventional media images, thus endorsing the importance of extending the body image dissatisfaction literature by taking into account emerging social media formats.
Expression of ANXA1 is higher in breast cancer patients with BRCA mutations, and is associated with worse survival, particularly in those with HER2+ tumors, suggesting that ANXA1 could be used as a biomarker to predict prognosis in high risk patients.
Development of a new Burkitt and diffuse large B-cell lymphoma classifier based on two previous classifiers that works effectively on paraffin embedded samples and provides useful information for clinical decisions.
A characterization of the genomic binding pattern of ALKBH3 and gene expression in prostate cancer cells reveals this oxidative DNA demethylase strongly binds a small number of highly active gene promoters.
An exquisitely preserved fossil rhizome from a Jurassic era species of royal fern adds new morphological evidence to the controversial question of these plants evolutionary origins.
Larger brain size in males is a pattern persisting throughout primate and human evolution; new experiments suggest a major role for estrogen in down-regulating genes linked to brain size, resulting in the smaller female brain size.
