Saving Young Lives in Zambia

submitted by: busph
Anti-malarial drugs are being used inappropriately for sick children in Zambia -- a problem that can be addressed by arming community health workers with a simple rapid-diagnostic test and a supply of antibiotics, a study led by researchers at Boston University School of Public Health has found. Listen to Kojo Yeboah-Antwi, assistant professor of international health at BUSPH, and David Hamer, professor of international health at BUSPH, discuss the study. Learn more at...

Tiny Conspiracies (MWV31)

submitted by: MicrobeWorld
Bacteria communicate with chemical languages that allow them to synchronize their behavior and thereby act as multi-cellular organisms. This process, called quorum sensing, enables bacteria to do things they can’t do as a single cell, like successfully infect and cause disease in humans. Bonnie Bassler, Ph.D., the Squibb Professor of Molecular Biology at Princeton University and President-elect for the American Society for Microbiology, has been researching strategies that can interfere...

Apicomplexan Parasites, Pathogen Genome Informatics, and the Evolution of Eukaryotic Organelles: Part 3C: Designing and mining pathogen genome databases: From genes to drugs and vaccines (25:45)

submitted by: video_collector
With the emergence of genomic-scale datasets representing all of the genes in the genome, all of the proteins in a cell or tissue, and all of the interactions and signals in an organism, biologists are increasingly faced with the challenge of how to store, integrate, and interrogate this information. How can we effectively mine large-scale datasets to expedite biological discovery, for example in the identification of new targets for anti-parasitic drug and vaccine design? Computational...

Rabbit Models for Alzheimer's Disease

submitted by: alex01
Diana Woodruff-Pak (Temple University, Philadelphia, PA) used cholesterol-fed rabbits as a model of AD for evaluation of currently available and potential anti-Alzheimer drugs. These animals developed typical Alzheimer pathology, including behavioral changes and deposition of ß-amyloid and even tau. Galantamine and donepezil partially protected animals from Alzheimer symptomatology.

Sodium Channels and Pain

submitted by: alex01
S. Waxman, MD, PhD. - Medical need for new analgesics is discussed by S. Waxman (Yale University) who evaluated the role of selective subtypes of sodium channels, particularly 1.7 and 1.8 subtypes, in the perception of pain. There is an unmet medical need for drugs to treat chronic pain and inhibitors of selective sodium channels are in development as novel analgesics.

AMPA Ligands in Neuroprotection

submitted by: alex01
Michael Spedding (Institute Internatinales Servier, Paris, France) described how neuroprotection can be achieved by either by blockade or by stimulation of AMPA (a-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors. Low threshold AMPA receptor stimulation leads to the release of BDNF (brain-derived neurotrophic factor) which is neuroprotective. Blockade of AMPA receptors reduces excitotoxicity leading to neuroprotection. BDNF is a major activity-dependent neurotrophic factor...
