Researchers at Yale School of Medicine have found that analyzing proteins in urine is a simple and objective method to diagnose and classify preeclampsia (PE), a complication of pregnancy causing high blood pressure after 20 weeks of gestation.
The work will be presented at the 26th Annual Society for Maternal-Fetal Medicine (SMFM) meeting on February 3 by Irina A. Buhimschi, M.D., assistant professor in the Department of Obstetrics, Gynecology & Reproductive Sciences.

Women who feel that they become more forgetful as menopause approaches shouldn’t just “fuhgetabout it”: There may be something to their own widespread reports that they’re more likely to forget things as menopause approaches, say scientists who reported results from a small study today at the annual meeting of the International Neuropsychological Society in Boston.
The team from the University of Rochester Medical Center found that the issue is not really impaired memory. Instead, the
The new device is to be used for cleaning and desinfecting the instruments very soon after the surgical procedure. The device offers purging with water,…

A study published Feb. 1 in the journal Bioscience finds that giving economic value to environmental systems may actually help preserve those systems in the long run. The study, led by University of Pittsburgh Graduate School of Public and International Affairs (GSPIA) Professor Stephen Farber and titled “Linking Ecology and Economics for Ecosystem Management,” uses several case studies to illustrate how an e
A single gene apparently thwarts a disease-causing invader that creates a fuzzy gray coating on flowers, fruits and vegetables. But the same gene provides access to a different type of pathogen.
A Purdue University plant molecular biologist and his collaborators in Austria and North Carolina identified the gene that helps plants recognize pathogens and also triggers a defense against disease. The gene and its defense mechanisms are similar to an immunity pathway found in people
An estimated 63 million adults have low-density lipoprotein cholesterol (LDL-C) levels higher than what would be ideal as recommended by the National Institutes of Health.
Of that group, 38 million are people with health conditions that put them at increased risk for cardiovascular disease.
These findings, by Stephen D. Persell and co-researchers at Northwestern University Feinberg School of Medicine, are reported in the February issue of the Journal of General Intern
Obesity, long known as a cause of type II diabetes, may accelerate the onset of type 1 diabetes in some – but not all – groups of younger patients, according to research at Wake Forest University School of Medicine and six clinical sites nationally.
“The increasing prevalence of childhood obesity may substantially account for the younger age at onset of type 1 diabetes observed in various populations,” said the research team, writing in the February issue of Diabetes Care.
New research suggests that the lower survival rates of blacks with lung cancer may be explained by access to care. The study, by Wake Forest University Baptist Medical Center researchers and colleagues is reported in the January issue of the Journal of Clinical Oncology.
“The results were intriguing,” said principal investigator A. William Blackstock, M.D., “When offered equivalent therapy, the outcome for black patients was the same as that of non-blacks.”

The high-fat “diet” that diabetic heart muscle consumes helps make cardiovascular disease the most common killer of diabetic patients, according to a study done at Washington University School of Medicine in St. Louis. The study will appear in the February 7 issue of the Journal of the American College of Cardiology and is now available online.
Sixty-five percent of people with diabetes die from heart attack or stroke. When the researchers investigated fuel consumption in heart
Could engineers have known ahead of time exactly how much pressure the levees protecting New Orleans could withstand before giving way? Is it possible to predict when and under what conditions material wear and tear will become critical, causing planes to crash or bridges to collapse? A study by Weizmann Institute scientists takes a new and original approach to the study of how materials fracture and split apart.
When force is applied to a material (say, a rock hitting a pane of glass
Changes in the tissue environment of the breast that occur after pregnancy promote the metastasis of breast tumor cells. The paper by McDaniel et al., “Remodeling of the mammary microenvironment following lactation promotes breast tumor cell metastasis,” appears in the February issue of The American Journal of Pathology and is accompanied by a commentary.
This work also highlights an important shift in thinking about what influences cancers to metastasize: the move from stu
Women suffering from urinary incontinence can benefit from pelvic floor muscle training, commonly known as Kegel exercises, according to a new review of studies.
A supervised regimen of Kegel exercises for at least three months was found to be especially effective for stress incontinence. Men also can use Kegel exercises, but were not included in the analysis.
The systematic review, led by Jean Hay-Smith, Ph.D., of the Wellington School of Medicine and Health Sciences at the
Is there a universal neural code for sensation, similar to the genetic code, in which the complexity of sense and experience can be reduced to a few simple rules? According to Prof. Ehud Ahissar of the Weizmann Institute’s Neurobiology Department, the answer might be no. He and his team have been studying how rats use their whiskers to sense their environment, and have found that the seemingly simple act of feeling out a 3-D object requires three different types of code.
Rats’ wh
Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely. Described in a new paper in Proceedings of the National Academy of Sciences,* the NIST nanotubes may have biotechnology applications as channels for tiny volumes of chemicals in nanofluidic reactor devices, for example, or as the “world’s smallest hypodermic needles” for injecting molec
A new report released today finds that the illegal trade in the Roti Island snake-necked turtle, found only on one island in Indonesia, has left it all but extinct in the wild. Exotic pet enthusiasts in Europe, North America and East Asia are fueling the illegal trade for the turtle, often without realizing that they are contributing to its demise. No legal trade of this species has been allowed since 2001.
The report by TRAFFIC, the wildlife trade monitoring network of WWF and IUCN, “T
Scientists at the Weizmann Institute of Science recently discovered a new source of well-preserved ancient DNA in fossil bones. Their findings were published in the Proceedings of the National Academy of Sciences (PNAS).
Fossil DNA is a potential source of information on the evolution, population dynamics, migrations, diets and diseases of animals and humans. But if it is not well preserved or becomes contaminated by modern DNA, the results are uninterpretable.
