Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin and can exhibit anti-cariogenic activity that allows the release and uptake of fluoride ions. They also possess the ability to render color. The setting reaction of GICs is a neutralization reaction that results in the formation of polycarboxylate salts. The most important GIC modification process involves the addition of resin components, resulting in the development of resin [...]

Major depressive disorder (MDD) is a debilitating illness that places a great burden on global health. A ketogenic diet, which has traditionally been used for treating refractory epileptic disorders, is being increasingly explored for its potential of alleviating other neuropsychiatric conditions. Providing an up-to-date summary on the ketogenic diet’s potential to alleviate MDD, its neurobiological basis, and preliminary clinical evidence. A structured literature survey was performed, and a narrative review was wr [...]

The world is becoming more dependent on energy resources, which translates into political dependency on energy-exported states. This will significantly impact the economy, transport, and the environment around the world. Railway transport is becoming an essential mode of transportation because it can operate on an electrified network and has zero carbon emissions. High-Speed Railways (HSR) is an energy-intensive transport system, and it is important economically and environmentally to reduce the amount of used ener [...]

Climate change has been identified as one of the biggest issues plaguing human life at present. Hence, immense attention is being paid to developing methods that can potentially reduce carbon dioxide emission. With the help of carbon-negative concrete, manufactured from alternative binders and cured with waste carbon dioxide, a major part of the manufacturing industries that emit carbon dioxide can be potentially turned into a carbon sink. In this study, the waste material streams in Finland, suitable for disposing [...]

Broccoli has long been reported to exert a positive impact on human health. It contains high levels of isocyanates, the most important of which is sulforaphane (SFN). Numerous studies have demonstrated that SFN can be used as an effective supplement for treating a variety of diseases. In addition, it is known to possess anti-cancer properties such as chemopreventive properties against gastrointestinal, breast, lung, bladder, prostate, and other cancers. The reported data indicates that broccoli could be a potent in [...]

Biodegradable plastics/polymers may serve as a promising solution to the global problem of plastic waste accumulation in oceans and soil and may significantly reduce carbon emissions from the manufacturing process, since the materials used to make biodegradable polymers are carbon-based and emitted during the synthesis processes. This article systematically reviewed the existing and closely related scientific literature on materials, biomaterials, and biodegradable materials to find answers on how to effectively st [...]

World socio-political growth is shaped by globalization, integration, and multiculturalism, which also impact individual self-perception. Understanding personal development requires studying self-awareness, self-identification, and influence to identify internal requirements and external influences. The study examined self-awareness, self-identification, influence, and their relationships, as well as psychological interventions for self-assessment and self-realization. To attain the research goal, analysis, synthes [...]

Background: After fatigue, pain is one of the major complaints from cancer patients. Regular use of Class 1 analgesics may cause side effects and is not always sufficient to relieve pain. Homeopathy is the complementary and integrative medicine most frequently used in France in supportive care in oncology (SCO). What is its place in the treatment of pain? Method: Extraction and analysis of results concerning pain from three surveys, two of which were carried out in France, on the main indications of homeopathy in S [...]

On the Washington and Oregon coast of the NE Pacific Ocean from 2008-2015, we found that juveniles represented 83% of Northern Fulmars that were beached. In comparison to older birds, juveniles averaged more mass and pieces of plastic in stomachs. This reflected relatively larger plastic loads in the cranial stomach section, the proventriculus, which we found was associated with relatively large accumulations in the caudal stomach section, the ventriculus. We estimate that the proventriculus could retain almost 10 [...]

There is a current need for tissue and organ repairs, replacement, and regeneration for patients who suffer from diseased or damaged tissues or organs. This situation is continuously on the rise and the supply of this form of therapy does not meet the patients demand mostly due to lack of donors and biocompatibility issues which causes immune system rejection of the implants. To succeed through these limitations, researchers are currently investigating the use of scaffolds as another approach for implants. The conv [...]
