Mouse genome consists of 10-nm chromatin fibres

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibres but did not find evidence for the wider 30-nm fibres that were previously thought to be important components of the DNA architecture.

BPA exposure can impact thyroid hormones in pregnant women and newborns

Bisphenol A (BPA), an estrogen-like compound that has drawn increased scrutiny in recent years, has been linked to changes in thyroid hormone levels in pregnant women and newborn boys, according to a new study by researchers at the University of California, Berkeley.

Esthesiometry may help vision professionals in evaluating dry eyes

A simple test of eyelid sensitivity may help vision professionals in evaluating one of the most common eye-related symptoms: dry eyes. A new study linking increased eyelid sensitivity to decreased function of the eyelid margins is presented in the article - " Lid Margins: Sensitivity, Staining, Meibomian Gland Dysfunction, and Symptoms", appearing in the October issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Treatment with Lfcin4-14 reduces DNA damage in colon cancer cells exposed to UV light

Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. A group of scientists in Sweden found that lactoferricin4-14 (Lfcin4-14), a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet (UV) light.

New mouse model could foster ALS, Paget's and dementia breakthroughs

Efforts to treat disorders like Lou Gehrig's disease, Paget's disease, inclusion body myopathy and dementia will receive a considerable boost from a new research model created by UC Irvine scientists.

Digital mammography boosts detection of life-threatening breast cancer

New research from the Netherlands shows that the switch from screen film mammography (SFM) to digital mammography (DM) in large, population-based breast cancer screening programs improves the detection of life-threatening cancer without significantly increasing detection of clinically insignificant disease. Results of the study are published online in the journal Radiology.
