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.
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.
Cuts, scrapes, blisters, burns, splinters, and punctures - there are a number of ways our skin can be broken.
Cuts, scrapes, blisters, burns, splinters, and punctures - there are a number of ways our skin can be broken. Most treatments for skin wounds involve simply placing a barrier over them (usually an adhesive gauze bandage) to keep it moist, limit pain, and reduce exposure to infectious microbes, but do not actively assist in the healing process.
Postnova Analytics reports on a new method for the accurate molecular weight determination of complex polysaccharides (Chitosans) using asymmetric flow field flow fractionation (AF4) coupled with multi-angle light scattering (MALS) and differential refractive index (RI) detectors.
A team of researchers from Universidad Politécnica de Madrid and Universidade de Trás-os-Montes e Alto Douro along with other research institutions have developed a method that will allow us to reduce the toxicity of gluten for people who suffer from celiac disease.
Livestock farming is destroying our planet. It is a major cause of land and water degradation, biodiversity loss, acid rain, coral reef degeneration, deforestation - and of course, climate change.
Multi-Walled Carbon Nanotubes is the name that is derived from their structure and walls are formed by one atom thick sheet of carbon.
Electrochemical sensors and biosensors allow researchers to measure small quantities of chemicals or physico-chemical parameters in experimental settings.
Multi-Walled Carbon Nanotubes (MWCNTs) are characterized by walls formed by a one atom thick sheet of carbon.
Scientists have developed a new way to deliver anti-parasitic medicines more efficiently.
