Chitosan is a naturally occuring polymer isolated from crab and shrimp shells. Chitosan has shown promise as a carrier of anticancer drugs, antitumor genes, and other novel therapeutics.
Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at at the Institut national de la recherche scientifique, and her team have developed a packaging film that can keep strawberries fresh for up to 12 days.
Researchers have reviewed different types of nanomaterials and how they can be used for the detection, prevention, and treatment of coronavirus disease 2019 (COVID-19).
The first global review of complementary medicines (herbal and dietary supplements) for weight loss in 16 years--combining 121 randomized placebo-controlled trials including nearly 10,000 adults--suggests that their use cannot be justified based on the current evidence.
Researchers review the various properties and use of nanoparticles in targeting SARS-CoV-2 and how they could be used to develop new therapeutics and diagnostics for SARS-CoV-2.
Fixing traumatic injuries to the skin and bones of the face and skull is difficult because of the many layers of different types of tissues involved, but now, researchers have repaired such defects in a rat model using bioprinting during surgery, and their work may lead to faster and better methods of healing skin and bones.
A team of scientists reviewed the nanoencapsulation approaches of synergistic compounds (Lectins, Caffeine, Cocoa, Flavonoids, Quercetin) and the role of nanotechnology in addressing the COVID-19 pandemic.
A team of experts has tested the immune responses elicited by mucosal homologous plasmid and a heterologous immunization strategy using a plasmid vaccine and a Modified Vaccinia Ankara (MVA) expressing SARS-CoV-2 spike (S) and nucleocapsid (N) antigens.
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed insulin nanoparticles that may one day become the basis for an oral medicine, and an alternative to insulin injections for diabetic patients.
A team of scientists led by Nanyang Technological University, Singapore has invented an artificial olfactory system that mimics the mammalian nose to assess the freshness of meat accurately.
A new study published on the preprint server bioRxiv reports the elucidation of the mechanism of inhibition of SARS-CoV-2 by a non-nucleotide inhibitor called suramin. This is the first such compound to be shown to have such activity and shows promise for use as a repurposed drug against COVID-19.
How do you test, in early-stage research, whether a potential pharmaceutical effectively targets a human tumor, organ, or some other part of the body? How do you grow a new hand or some other body part?
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination treatment strategy to tackle certain antibiotic-tolerant infections.
Infusing prepared foods with an edible coating that contains green tea extract may lower consumers' chances of catching the highly contagious norovirus by eating contaminated food, new research suggests.
In Japan, an increase in the aging population has exacerbated the demand for regenerative medicine to address increasingly common diseases, such as knee osteoarthritis.
In what reads like science fiction, a new study published in the journal ACS Central Science reports the development of bandages that detect the presence of bacteria in wounds and change color, depending on whether they are drug-sensitive or drug-resistant. This is an important step in helping patients recover better.
An important randomized trial shows that when vitamin D is supplemented at high doses in the last three months of pregnancy, there is a fall in the occurrence of enamel defects in the deciduous (milk) and permanent teeth of the offspring by half, over the next 6 years, compared to a low dose supplementation. However, the incidence of caries was not affected.
In response to environmental changes and nutrient starvation, cells are known to undergo extreme alterations. This includes switching from one type to another (“differentiation”) and changes in metabolic pathways (“metabolic switching”).
All living organisms respond and adapt to changes in their environment. These responses are sometimes so significant that they cause alterations in the internal metabolic cycles of the organism--a process called "metabolic switching." For example, rice blast fungus--a pathogenic fungal species that causes the "rice blast" infection in rice crops--switches to the "glyoxylate cycle" when the nutrient source starts to deplete.
University of Florida scientists believe they can develop new antimicrobials that will benefit dairy cattle and, eventually, humans by treating bacteria that normally resist antibiotics.
Extracts of the herb Withania coagulans, or Paneer dodi, are used in traditional Indian medicine. Although some healers claim that W. coagulans can help treat diabetes, the bitter-tasting plant hasn't been studied extensively by scientists.
