...han 14,000 women an estimated 85 to 90 percent of those eligible responded to questionnaires that gauged how depressed or anxious they were at multiple points early on in, late in, and after their pregnancy. Later on, the women were then asked to report on their childs sleep habits at 6, 18 and 30 months...

Genomic Analysis Uncovers New Targets for HIV Vaccine

... studied. The CHAVI investigators wanted to study those patients who had many sequential blood samples taken during this plateau in viral load. Before their analyses began collaborators in the EuroChavi consortium, coordinated by Amalio Telenti at the University of Lausanne, sifted through data collected ...

One species, many genomes

...n with other organisms, on the other hand, such as those responsible for defense against pathogens or infections, are much more variable than the average gene. "The genetic variability appears to reflect adaptation of local circumstances," says Weigel. It is likely that such variable genes allow plants to ...

Common cancer gene sends death order to tiny killer

...to contain damaged or missing p53, they found that those cells had limited or zero miR-34a. "With no p53 gene or miR-34a to stem tumor development, there's no brake in pancreatic cells and uncontrolled growth leads to cancer," says Anirban Maitra, M.B.B.S., associate professor of pathology, oncology an...

Innovative smallpox vaccine research study to be conducted at Case Medical Center

...nough to give the vaccine to all individuals, even those whose immune systems are suppressed,” says Dr. Salata. “Our hope is that the new vaccine will be a safer alternative to the current vaccine.” UHCMC and the School of Medicine will act as a subunit of St. Louis University’s Center for Vaccine Devel...

Blood test may help signal tumor's remission, return in throat cancer patients

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...ies correlate mutations in non-coding regions with those in coding regions, and that some repetitive regions of DNA (not exam-ined in this study) are associated with genes. “It stands to reason that mutations could also interfere with genes, but our ongoing research looks to clarify the severity of DNA...

Researchers track how spores break out of dormant state

...s, including Marco Plomp, lead author at LLNL, and those from Children’s Hospital Oakland Research Institute and Northwestern University, used AFM to identify disassembly of the outer spore coat rodlet structures, which appear to be structurally similar to amyloid fibrils that have been associated with neu...

New study reports hotel guests at risk from carbon monoxide poisoning

...20 rescue personnel were accidentally poisoned. Of those poisoned, 27 died, 66 developed pathological conditions, and 6 had conditions resulting in a jury verdict. Jury verdicts have averaged $4.8 million per incident (range=$1 million-17.5 million). Poisoning occurred at hotels of all classes. Accordi...

Snoring in children might be an allergic type disease

... pre-school children with rhinitis were similar to those for allergic diseases in a group of children who have been monitored since before they were born. “Our findings were consistent with the view that snoring forms part of the spectrum of allergic diseases in childhood,” he said. While the study f...

Caribbean frogs started with a single, ancient voyage on a raft from South America

...walked there across land bridges that existed when those islands were connected in a geologic arc about 70-to-80-million years ago. A second major theory proposed that they arrived, instead, by rafting across the Caribbean Sea after the giant asteroid impact near Cuba 65-million years ago, which is widely...

For many decades, aP2 was believed to act only in fat cells. In 2001, Hotamisligil and a collaborator discovered that aP2 is also expressed in...
