Study finds that a woman's chances of having twins can be modified by diet

...y that a woman's chance of having twins appears to correlate directly with her blood level of insulin-like growth factor. "Because multiple gestations are more prone to complications such as premature delivery, congenital defects and pregnancy-induced hypertension in the mother than singleton pregnancies, the...

A dichotomy in migration patterns found for sea turtles in east Atlantic

...ct foraging strategies. The differing strategies correlate with body size, which may be linked tothe different diets of the two groups. Turtles migrating to shallow coastalwaters-the so-called neritic environment-were larger, and they feed on thearthropods and mollusks that are normally abundant in this food...

New tool tracks brain development in babies

...hether the detected fiber abnormalities ultimately correlate with outcomes." Hypoxic ischemia remains an important cause of infant mortality and morbidity, with an incidence of between one and two per 1,000 live births in the United States. ...

In a technical tour de force, Salk scientists take a global view of the epigenome

... methylation across the body of a gene appeared to correlate with higher expression. Different cell types show different methylation patterns. DNA methylation in stem cells differs from that in a mature skin or nerve cell. Part of the makeover mature cells must undergo for therapeutic cloning purposes will l...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

He found that, overall, men who were confident about their fatherhood going into the test were only wrong 1.7 percent of the time, that is, they were indeed the child's father more than 98 percent of the time. Men who were dubious about thei...

Ticks, flukes, and genomics: Emerging pathogens revealed

... diseases different? How are they the same? Can we correlate certain genes with certain characteristics? For the first time, our comparative genomics database offers a resource for tackling these questions." Recognized since at least the 1930s, ehrlichiosis sickens not only humans, but also dogs, cattle, shee...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

... researchers know that variants of the NOS1AP gene correlate with QT interval length, they hope to figure out exactly how the DNA sequence variations alter the function of the gene, and how changes in gene function affects heart rhythm. ...

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...l activity in areas beyond visual area 2 appear to correlate with perception." They also found that the areas of the brain related to visual perception appear to reside exclusively in the occipital lobe (at the back of the head.)

The precise characterization of this myosin-actin interface is critical, evident by the way a single amino acid change in myosin leads to familial hypertrophic cardiomyopathy (FHC), an undetectable condition resulti...

Rutgers researchers scientifically link dancing ability to mate quality

...lay," Brown said. "Our results with human subjects correlate with that expectation. More symmetrical men put on a better show, and women notice." The researchers worked with a group of Jamaicans, building on earlier studies of physical symmetry in that population. The test group was ideal for a scientific stu...

Beach pollution is worst during new and full moon

...hat enterococci from beach sands and wrack may not correlate with health risk the same way as enterococci from runoff or sewage. "We just don't know for sure, since no one has done an epidemiological study to connect human illness to enterococci from non-point sources other than runoff," Boehm says. "We need t...

Bacteria in Household Dust May Trigger Asthma Symptoms

...n. A disease association analysis was performed to correlate endotoxin concentrations to specific health outcomes. “When we analyzed the dust samples, we found that kitchen and living room floors had the highest concentrations of endotoxin,?said Darryl C. Zeldin, M.D., a Senior Investigator at NIEHS. “However...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...nges associated with methamphetamine abuse did not correlate with the amount of the drug a person ingested. However, the study results suggest that younger methamphetamine abusers showed larger effects in some brain regions. Among HIV-infected individuals, the researchers noted a direct association between the...

Researchers identify genes associated with lung transplant rejection

...ts in each patient. They identified six genes that correlate with lymphocytic bronchitis, potentially opening the way to a genetic test that would identify OB before it manifests. "The beauty of this approach is that it could be applied in a regular laboratory," Caughey says. However, he cautions, "we need to...
