Nanoparticles signal the onset of Alzheimer’s disease

Nanoparticles signal the onset of Alzheimer’s disease

A failing memory coupled with a growing inability to carry out the simplest tasks may be a symptom of Alzheimer’s disease, where a build-up of solid plaques, composed of specific abnormal protein fragments, slowly destroys the brain’s nerve cells. So far, there have been very few methods in which the potentially fatal disease can beRead more about Nanoparticles signal the onset of Alzheimer’s disease[…]

Healing skin wounds using bamboo cellulose nanocrystals

Healing skin wounds using bamboo cellulose nanocrystals

Nanobiocomposites made of bamboo cellulose nanocrystals and silver nanoparticles can accelerate healing of skin wounds in mice, new research shows1. These nanocomposites could be converted to films and ointment, useful as wound-healing dressing material. Existing wound-dressing materials have drawbacks such as foul smell, low porosity and poor-healing capacity. Some are also toxic to biological cells.Read more about Healing skin wounds using bamboo cellulose nanocrystals[…]

A brain chemical can combat depression

A brain chemical can combat depression

Astrocytes transport nutrients such as lactate to neurons. Lactate activates certain genes linked to neurons’ plasticity, particularly at the nerve junction known as synapse, contributing to the formation of long-term memory. When astrocytes’ population dwindles, lactate levels in the brain fall, causing neurons to malfunction and leading to brain disorders such as depression. Now, aRead more about A brain chemical can combat depression[…]
