Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

Should breast tissue be screened for cancer after mammoplasty?

Young women undergoing cosmetic breast reduction surgery are being screened for cancer without their informed consent, according to a paper published on bmj.com.

New staging technique might save bladders in some bladder cancer patients

Pathologists have reported encouraging results from a new technique to increase the accuracy of staging bladder cancer tumors that could reduce the need to remove bladders from some patients.

How chemicals present in cranberries prevent urinary tract infections

Chemicals present in cranberries - and not the acidity of cranberry juice, as previously thought - prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food.

Hopkins community nursing showcases public health principles

Public Health Week, April 7-13, annually highlights health promotion, disease prevention, and early intervention, but for the faculty and students at the Johns Hopkins University School of Nursing (JHUSON), every week is public health week.

New optical technology shows promise in detecting pancreatic cancer

Optical technology developed by a Northwestern University professor of biomedical engineering has been shown to be effective in detecting the presence of pancreatic cancer through analysis of neighboring tissue in the duodenum, according to clinical trial results published in the journal Disease Markers.

Spun-sugar filaments show potential for regenerating nerves

Researchers at Purdue University have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease.

Determining risk for pancreatic cancer

In the latest clinical trial for a technique to detect pancreatic cancer, researchers found they could differentiate cells that are cancerous from those that are benign, pre-cancerous, or even early stage indicators called mucinous cystic lesions.

Mathematical method helps to select human embryos

A team of researchers from the University of the Basque Country (UPV-EHU) have developed a mathematical classification which makes it possible to select human embryos for use in assisted reproduction treatments. Scientists have used the morphology of embryos to select the best candidates for implantation in the woman's uterus.

Gold nanoparticles improve gene regulation

Investigators at Northwestern University have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in cancer. As a result of this discovery, cancer researchers have at their disposal a relatively straightforward method of delivering these potent gene-regulating agents into targeted cells.

Presence of a biomarker in regional lymph nodes predicts disease recurrence in colorectal cancer

Findings published in the Journal of the American Medical Association by researchers at Thomas Jefferson University show that the presence of a biomarker in regional lymph nodes is an independent predictor of disease recurrence in patients with colorectal cancer.
