Abstract Background This study aimed to explore the performance of Revolution CT virtual monoenergetic images (VMI) combined with the multi-material artifact reduction (MMAR) technique in reducing metal artifacts in oral and maxillofacial imaging. Results There were significant differences in image quality scores between VMI + MMAR images...

Abstract Many decisions under risk and uncertainty are made under physical or emotional stress. A recent meta‐analysis suggested that stress reliably influences risk taking but did not find a relation between single measures of stress such as cortisol and risk taking. One reason for the conflicting findings could be that the influence of stress on risk taking depends not only on physiological but also on psychological stress responses, in particular affective valence. We tested this hypothesis...

Making your own hand sanitizer is easy. And yes, you technically can use vodka. (Sandra Gutierrez G./)Follow all of PopSci’s COVID-19 coverage here, including travel advice, pregnancy concerns, and the latest findings on the virus itself.You probably haven’t considered making your own hand sanitizer. Stores sell it for cheap, in a variety of scents and styles, and it’s basically as good as it can be.

These smart little guys knew which bowl would be more likely to land them a black token, and in return, a yummy snack. (Amalia Bastos/)Let’s say there are two bowls of M&Ms in front of you: one with 90 blue candies and 10 yellow candies, one with 50 blue and 50 yellow. If blue were your favorite color — which bowl would you choose to blindly pick from? Or, if someone dug into the first jar, what color would you guess they have?“Seeing as the majority is blue candies, they should guess blue,”...

A self-driving Jaguar I-Pace. (Waymo/)Just like cars with humans behind the wheel, self-driving vehicles need to see the world around them in careful detail. And since they don’t have eyes like a regular driver does, they use hardware-based perception systems to observe the streetscape, plus software and AI to make sense of it all. Autonomous car company Waymo, a Google sibling and part of Alphabet, has just published a detailed explainer about the newest version of the sensors on some of its vehicles....

Punnet squares aren't the best way to predict a kid's eye color. (Candice Picard/Unsplash/)Most of us learned what we know about eye color from a chart in grade-school biology. You know, the one that shows that two brown-eyed parents will likely have brown-eyed kids, and two blue-eyed parents are pretty much destined to have blue-eyed kids. It might have come with little color codes, clear-cut percentages, and neat lines of inheritance. But the story of how eye color is passed down is more complicated—and...

Anything that can call Titan’s lakes home would have to be one tough critter. (NASA/JPL-Caltech/)Saturn’s moon Titan would not be a comfy place for Earthlike microbes, even as alien worlds go. It lacks a global ocean like the ones found on Europa and Enceladus, and it doesn’t enjoy the (relatively) balmy climate of Mars. But it does look strikingly Earthlike in one respect—lakes with crinkled shorelines speckle its surface.Those lakes are filled with methane and ethane rather than water, and any...

Drug allergy de-labelling is when a listed drug is removed from the allergy section. In an ideal scenario, this is then communicated in a streamlined process to the patient and their healthcare settings. The future of large-scale drug allergy de-labelling rests in multiple arenas: culture shifts, easily adapted tools to de-label our largest drug allergy categories, and electronic health record (EHR) cross-talk. The present functionalities of most EHR allergy sections and ignorance of their content,...

Morton's neuroma is a misnomer in the sense that the digital nerve lesion in question is not a true neuroma of a nerve, but rather, perineural fibrosis. Nonetheless, for many decades, optimal treatment for its metatarsalgia was nerve resection due to the fact it was an identifiable anatomical mass. Dellon 1 in 1992 popularized the theory that the pain derived in fact from digital nerve compression by the deep transverse intermetatarsal ligament. Then it stood to reason pain caused by nerve entrapment...

Previous models have theorized that, during phonation, skewing of the glottal waveform (which is correlated with acoustic intensity) occurred because of inertance of the vocal tract. Later, we reported that skewing of the flow rate waveform can occur without the presence of a vocal tract in an excised canine larynx. We hypothesized that in the absence of a vocal tract, the skewing formed when dynamic pressures acted on the glottal wall during the closing phase; such pressures were greatly affected...

Engaged teachers feel rewarded at work, complete assignments in a positive manner and, often immerse themselves in their work. However, voice complaints are more common for teachers than other professionals which may negatively affect their engagement. This study aims to determine the relationship between work engagement and voice complaints for elementary school teachers.

The number of women studying in medical schools is increasing, and the relative proportion of female consultants in surgical and leadership roles is lagging behind, relatively, and so a new drive for promoting and supporting women in surgery has evolved. A part of this was the creation of the Society of Women in Oral and Maxillofacial Surgery. This short communication gives proceedings of the inaugural conference of SWiMS and discusses the need for greater promotion of women in the speciality (and...

The aim of this study was to assess the quality of life (QoL) of patients who had total replacement of the temporomandibular joint (TMJ) using a modified short form 36 (SF36) questionnaire, which is validated for use in this context. A total of 36 patients (32 female, 4 male, mean (range) age at the time of operation 44.5 (19-74) years) who had TMJ replacements between 2013 and 2016 were evaluated. Each completed a questionnaire preoperatively and at one year postoperatively. Postoperatively there...

The lateral arm flap (LAF) may offer an alternative option for oral cavity repair. Twenty-five Chinese patients with oral cavity defects were reconstructed with a LAF. The anatomical characteristics of the flap, the donor site complications, and the functional and aesthetic assessments of recipient site were reviewed. The overall flap survival was 96.0% (24/25patients). The average pedicle length was 7.07±1.09cm when it was cut off at the insert of the deltoid, with an average arterial diameter of...
