Return to Zambia MWV 17

submitted by: MicrobeWorld
The American Society for Microbiology is helping African nations foster a scientific community that is better able to address the current and future problems that threaten not only the local population, but the world at large. Like many African countries, Zambia and South Africa are deeply affected by HIV and tuberculosis, as well as a number of other infectious diseases. In March of 2008, ASM President Cliff Houston, Ph.D., traveled to Zambia and South Africa to gauge and assess the...

Breast cancer genes protect against some leukemias and lymphomas

submitted by: BernardFriedenson
Carriers of mutations in the breast cancer genes BRCA1 or BRCA2 have very high lifetime risks for breasts/ovarian cancer. Products of either gene have multiple functions including involvement in error-free double strand break repair. BRCA1 and BRCA2 genes are both components of a DNA damage response pathway that has the ability to return fragments of broken chromosomes back into their correct positions without ligating them elsewhere. But cancers at other sites may also occur without this...

Methylphenidate Decreased the Amount of Glucose Needed by the Brain to Perform a Cognitive Task

submitted by: noravolkow
The use of stimulants (methylphenidate and amphetamine) as cognitive enhancers by the general public is increasing and is controversial. It is still unclear how they work or why they improve performance in some individuals but impair it in others. To test the hypothesis that stimulants enhance signal to noise ratio of neuronal activity and thereby reduce cerebral activity by increasing efficiency, we measured the effects of methylphenidate on brain glucose utilization in healthy adults. We...

ATP deficit in oxygen-limited tumour cord growth (FF++)

submitted by: sast
This is a simulation of tumour cord growth , where cells suffer from hypoxia (energy deficit shown with colour). The tumour grows along the blood vessel (coincides with x -axis). Red line shows the position of the tumour–host interface. This particular simulation was programmed in FreeFEM++ out of curiousity. The source code for simulation may be found at http://code.google.com/p/cord . This video reflects work in progress and may be different from the final results .
