Plant Viruses and Crops by Roger Beachy, April 2008 - Part 1: Cell and Molecular Biology of Plant Virus Infection: Early Events and Mechanisms of Pathogenesis

submitted by: video_collector

This seminar describes the cell and molecular biology of plant virus infection. The first lecture will discuss how virus replication centers are set up in plants and how viruses use host cell mechanisms to facilitate cell to cell movement and eventual pathogenesis.

Apicomplexan Parasites, Pathogen Genome Informatics, and the Evolution of Eukaryotic Organelles by David S. Roos, May 2008 - Part 1: How to build a parasite

submitted by: video_collector
There are more than 5000 species of single-celled eukaryotes in the biological phylum known as the Apicomplexa, including the parasites responsible for malaria, neurological birth defects, and opportunistic infections associated with HIV/AIDS. These ancient protozoa provide a unique window into the evolution of subcellular organelles that have long fascinated cell biologists. Familiar features help to elucidate the origins, functions and design parameters for the secretory pathway,...

Emergence of Azole Resistance in Aspergillus fumigatus and Spread of a Single Resistance Mechanism.

submitted by: nelleke
Background Resistance to triazoles was recently reported in Aspergillus fumigatus isolates cultured from patients with invasive aspergillosis. The prevalence of azole resistance in A. fumigatus is unknown. We investigated the prevalence and spread of azole resistance using our culture collection that contained A. fumigatus isolates collected between 1994 and 2007. Methods and Findings We investigated the prevalence of itraconazole (ITZ) resistance in 1,912 clinical A. fumigatus...

Successful Aging: The Buzz on Successful Aging

submitted by: sjanderson

What does it mean to age successfully? After all, aren’t we accomplishing this just by being alive? The term "successful aging" is vague and leaves much to the imagination. Yet, there is a growing interest in this topic. UCSD’s Stein Institute for Research on Aging has embarked on its own research project to discover the secrets to success. This presentation provides insights related to successful aging and discuss current research findings and proposed models.

Antibiotics: Is a Strong Offense the Best Defense? (Part 3 of 3) MWV23

submitted by: MicrobeWorld
In the final episode of this 3 part video series on how to optimize antibiotic use and minimize the emergence of drug resistant pathogens, Dr. Linda Tollefson, Assistant Commissioner for Science at the U.S. Food and Drug Administration, goes in depth on the use of antimicrobial drugs in agriculture, their efficacy, and adverse human health consequences. Dr. Stuart Levy, professor of Molecular Biology and Microbiology at Tufts University School of Medicine, discusses policy, regulatory and...
