Several organisms have demonstrated the ability of synthesising biogenic selenium-containing nanoparticles. Such particles from biological sources have attracted great attention due to several proven activities as antioxidants or antimicrobial agents. However, little is known in terms of size (distribution), shapes

Alzheimer's disease (AD) brains are characterized by amyloid-beta-containing plaques and hyperphosphorylated tau-containing neurofibrillary tangles (NFTs); however, in frontotemporal dementia, the tau pathology manifests in the absence of overt amyloid-beta plaques. Therapeutic strategies so far have primarily been targeting amyloid-beta, although
