Bandages sense infections, change color, treat infection

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.

Vitamin D in pregnancy reduces risk of enamel defects in offspring

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.

Study uncovers how rice blast fungus uses its own cell wall to launch an attack

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”).

Extremely low concentrations of acetic acid could alter cellular processes in rice blast fungus

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.

Encapsulated Indian medicinal herb can reduce blood glucose levels in diabetic mice

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.

Bioinspired adhesive dressings could accelerate wound healing

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.

New combination method improves characterization of polysaccharides

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.
