Stimulating a Focal Pathway in the Brain Proves to Have Calming Effects
Ever heard the saying ‘laughter is the best medicine?’ What if it was the best medicine for brain surgery? It sounds farfetched, but neuroscientists have found that when they electrically stimulate one area of the brain, a person laughs and then feels an immediate...
Tools Help to Detect any Human Virus
When the Zika virus reared its ugly head, researchers began scrambling to identify the pathogen. Initially, the virus was hard to find in affected victims. Zika simply did not leave enough evidence behind to enable identification. However, scientists from the Broad...
New Materials that Drive Wound Healing
The science of tissue repair is constantly evolving. A new understanding of how the body repairs wounds is influencing the strategies used by the medical community. A great example of this is new TrAPs technology. TrAPs, or traction force-activated payloads,...
Mortality Rates are Rising for Two Generations
Life expectancy is a powerful method of determining the health of a country. A steady increase in life expectancy, considered the norm for decades, may no longer be the case. The last time it fell for several consecutive years was directly after World War I which was...
What is Virotherapy?
Usha Govindarajulu goes into further detail to explain the innovative field of virotherapy and what it means for cancer treatments in the future.
Comparing smoothing techniques in Cox models for exposure–response relationships
Abstract To allow for non-linear exposure-response relationships, we applied flexible non-parametric smoothing techniques to models of time to lung cancer mortality in two occupational cohorts with skewed exposure distributions. We focused on three different...
Quantifying bias due to allele misclassification in case-control studies of haplotypes
Abstract OBJECTIVES: Genotyping errors can induce biases in frequency estimates for haplotypes of single nucleotide polymorphisms (SNPs). Here, we considered the impact of SNP allele misclassification on haplotype odds ratio estimates from case-control studies of...
