Abstract Background Aesthetic porcelain veneers proved to be a long-term reliable prosthetic solution, ensuring minimal invasiveness. The use of veneers requires an adhesive cementation technique, so maintaining as much enamel as possible is to ensure lasting success. A diagnostic mock-up is a key tool that allows a preview of the outcome of the aesthetic restoration: it is obtainable both in an analog and digital way. With the recent...
Abstract Background Previous research revealed that luteolin could improve the activation of alkaline phosphatase (ALP) and osteocalcin in mouse osteoblasts. We aimed to determine the effect of luteolin on osteogenic differentiation of periodontal ligament cells (PDLCs). Methods Cultured human PDLCs (HPDLCs) were treated by luteolin at 0.01,...

The aim of this study was to examine the effect of MPH supplementation to whey protein (WP) and carbohydrate (CHO): (CHO-WP-MPH), on short-term recovery following high intensity performance, compared to an isoenergetic and isonitrogenous supplement of WP and CHO:...
Abstract Background TeaCrine® is the synthetic version to naturally occurring theacrine (1, 3, 7, 9-tetramethyluric acid) found in the leaves of Camellia kucha tea plants. A few studies have examined the effects of TeaCrine® on cognitive perception, but no research exists examining its effects on resistance exercise performance. The purpose of this study was to determine the efficacy of TeaCrine®, a caffeine-like compound, on maximal...
Abstract Background Whilst the ergogenic effects of carbohydrate intake during prolonged exercise are well-documented, few investigations have studied the effects of carbohydrate ingestion during cross-country skiing, a mode of exercise that presents unique metabolic demands on athletes due to the combined use of large upper- and lower-body muscle masses. Moreover, no previous studies have investigated exogenous carbohydrate oxidation...

AbstractBackgroundThe prediction of future obesity patterns is crucial for effective strategic planning. However, disproportionally changing body mass index (BMI) distributions pose particular challenges. Flexible modeling of the shape of BMI distributions may improve prediction performance.MethodsWe used data from repeated national health surveys conducted in Mexico, Colombia and Peru at four or five time points between 1988 and 2014. Data from all surveys except the last survey were used to construct...
AbstractBackgroundThe advent of very large cohort studies (n > 500 000) has given rise to prospective analyses of health outcomes being undertaken after short (<4 years) follow-up periods. However, these studies are potentially at risk of reverse causality bias. We investigated differences in the associations between self-reported physical activity and all-cause and cardiovascular disease (CVD) mortality, and incident CVD, using different follow-up time cut-offs and methods to account for reverse...
AbstractBackgroundThis study assessed the association between coal-mine-fire-related fine particulate matter (PM2.5) and medical-service utilization, following a 6-week coal-mine fire in Australia, in 2014.

I hate the term 4D printing. Abhor it. I was horrified when I saw it quicker than anticipated gain currency in our market and in the lexicons of journalists. But, in order to print a future for ourselves and this planet, I’ll happily jump on the wordforge myself in order to help us all. Now, I’ll be the first to admit that Industrie 5.0 is a bit of a stretch. But, it seems logical and this is all you need really. So what is Industrie 5.0?

When it comes to medical applications, we’ve seen 3D printing used in the past for healing and repairing wounds, whether through the use of 3D printed bandages, 3D printed blood platelets, or bio-based materials, like nanocellulose. Researchers Dr. Mohamed M. Kanjou, Hassan Abdulhakim, Gabriel Molina de Olyveira, and Pierre Basmaji published a paper, titled “3-D Print Celulose Nanoskin: Future Diabetic Wound Healing,” about using bacterial cellulose for the purposes of wound healing. “Most 3D printers...
Tools and insights to help people choose the right 3D printer, materials, or become more knowledgable about how disruptive technologies can benefit the industry, are very important. This is one of the reasons why a lot of well-established companies and startups are turning to webinars to help users boost their understanding of a 3D printer they already own or to attract new customers. Nevertheless, webinars take up time, usually around an hour or more. On average people spent one-third of their...
LiDar Truly I get too excited talking about technology, and I hope it shows. Although technology is awesome, there always lies a need for it to have a function or application. In a previous article, I briefly discussed cultural heritage and laser scanning.

The Internet of Things (IoT) has been heralded as one of the next big steps in our technological development. The vision is somewhat utopian: the system collects information, relaying it swiftly throughout a hyperconnected network and uses that data to discover insights and take action in order to improve our daily lives. It could save energy by making devices more efficient, optimize areas like infrastructure and traffic, help with waste management and personal health, and do so much more. The...
We’re so used to 3D printing being disruptive that we don’t, in my opinion, worry enough about being disrupted ourselves. Much 3D printing news is a seemingly endless me-too copycat conga line so we need to recognize when someone is doing something original. Fortify is doing something original, something original that is potentially disruptive to the 3D printing industry. The company has come out of obscurity to raise over $13 million for an integrated 3D printing solution for fiber-reinforced parts....

A natural resin, harz in German. In the face of apathy, new dreams are emerging. From a technocratic perspective, these new dreams make sense. But just as we’ve seen with the European dream, an ever closer union, needs backing from citizens. New dreams need to be passionately supported, easy to understand and easy to spread. A technocratic idea is not enough: we need to give this idea heart so that people can believe and support it. It needs to be scary, terrifying and powerful like all good nightmares...
Meat. Millions of people demand it. Global meat consumption has increased by 70% since the 1960s and is expected to keep on growing, while total production has grown five times in the same period. But experts are advising that if we keep moving along this path, the environmental footprint of raising livestock for meat consumption will be too much of a burden for the planet to bear. We already know that raising animals for food consumes more than half of all water used in the US alone, while producing...
