Growth factors during HCV therapy may be “cost-effective”, but are they “effective”?

Review: lactulose or lactitol may improve hepatic encephalopathy but may be less effective than antibiotics.

Drugs for Alzheimer's disease: are they effective?

OVERVIEW AD is a neurodegenerative process marked by neuronal loss and the deposition of abnormal proteins in the form of amyloid plaques and neurofibrillary tangles. Beta-amyloid deposition culminates in the production of extracellular amyloid plaques in the cerebral cortex and elsewhere in the central nervous system (CNS). Hyperphosphorylation of the intracellular tau protein results in neuro...

Bucket brigades revisited: Are they always effective?

Previous work on the dynamics of bucket brigades has focused on systems in which workers can be ordered with respect to their speeds and where this ordering does not change throughout the line. While this assumption is valid in most environments, it may not be satisfied in some. We consider such environments and explore the conditions under which bucket brigades continue to be effective (compar...

Biosynthesized silver nanoparticles: are they effective antimicrobials?

BACKGROUND Silver nanoparticles (AgNPs) are increasingly being used in medical applications. Therefore, cost effective and green methods for generating AgNPs are required. OBJECTIVES This study aimed towards the biosynthesis, characterisation, and determination of antimicrobial activity of AgNPs produced using Pseudomonas aeruginosa ATCC 27853. METHODS Culture conditions (AgNO3 concentratio...
