Experimental vaccine protects nonhuman primates when given after exposure to Marburg virus

...ity of life with symptoms such as fatigue, and are correlated with difficulties ranging from a higher rate of traffic tickets to increased mortality. In recent years, access to potent antiretroviral drugs in the United States and other developed countries has significantly improved the health, survival, and fu...

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

...ng or short QT interval. Only one particular SNP correlated with QT interval. That SNP was found near the NOS1AP gene, which has been studied for its function in nerve cells and was not previously suspected to play a role in heart function. However, the research team found that the NOS1AP gene is turned on in...

Animal models show that anabolic steroids flip the adolescent brain's switch for aggression

... Autopsy revealed that the outward aggressiveness correlated with inner changes in the brain. When the drugged hamsters were hostile hosts, a part of their brains called the anterior hypothalamus pumped out more of a neurotransmitter called vasopressin. By three weeks of withdrawal, vasopressin levels subsid...

Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful

...on varied widely within the region and was clearly correlated with human activities prior to the tsunami. In areas where fishing has been controlled, such as the Marine Protected Area on Pulau Weh and reefs managed under the traditional Acehnese system of Panglima Laut, coral cover was high. In contrast, reefs ...

New methods offer insight into regulatory DNA

...ge, it was investigated further. These genes were correlated with more than 750,000 SNPs ?sequence differences between individuals in the sample collection. A series of statistical tests were carried out to provide increased confidence in the association between gene activity and sequence variation. "Our samp...

Health of coral reefs detected from orbit

...und that observed changes in live coral cover were correlated to an existing bleaching event. Theoretical studies indicate that for each complete 300-metre pixel of coral under one metre of water it is possible to detect a 2% bleaching of live coral. MERIS should remain sensitive to detecting from 7-8% bleach...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

...i. He retrieved a spatial pattern of synchronized, correlated activity ?the memory trace ?from what appeared to be random fluctuations of neural activity. "The trace is like a fingerprint that disappears over time. It's strongest after the honeybee's initial exposure to an odor, but you can still detect its si...

Brain activity related to processing faces is similar in people with, without autism

...ition, Belger and Dichter pointed to research that correlated the amount of time autistic people looked at features of a face with activation of the amygdala, the "anxiety center" of the brain. They propose that the use of behavioral interventions aimed, perhaps, at de-sensitizing autistic individuals to the a...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

... "spike" in current with the MCF7 cells because it correlated with the greater IGF1R expression. "The technique could be used for detection and it could be used for recurring circulating tumor cells or micrometastases remaining from the originally treated tumor," explains co-author Eric Wickstrom, Ph.D., of ...

A new step towards an AIDS vaccine

...ogressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. High numbers of pDCs is related to successful control of HIV. In a paper appearing online on O...

Weapon performance determines mating success in the collared lizard

...reproductive success. However, no size measure was correlated with any estimate of mating success or with potential reproductive output. These results counter the conventional wisdom that bigger is always better, and they support the hypothesis that weapon performance, which is likely to directly influence figh...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...s who are also HIV-positive, decreased volumes are correlated with increased cognitive impairment in one brain region, the hippocampus. Dr. Jernigan explains that the changes seen in brain structures could be the result of inflammation in the brain and/or compensatory changes associated with methamphetamine to...

Muscle repair: Making a good system better, faster; implications for aging, disease

...lation (and) the extent of macrophage accumulation correlated with both the clearance of (damaged) protein after injury and the efficiency of regeneration," according to the report. Macrophage accumulation was impaired in injured muscle of uPA null mice and increased in PAI-1 null mice, compared to WT mice. At...

Researchers identify genes associated with lung transplant rejection

...ay beyond our expectations." The researchers then correlated the genetic test results with results from microscopic pathology examinations, tissue cultures, X-rays, CT scans, and breathing tests in each patient. They identified six genes that correlate with lymphocytic bronchitis, potentially opening the way t...

New Lab Research May Help Those Deafened By Immune System Attack

...immunofluorescence (IF) test based on KHRI-3. They correlated the results of those two tests with patients' response to steroid treatment, based on standard criteria and the results of hearing tests performed before and after treatment. They also considered patients' other autoimmune diseases, the length and pa...

Scientists find microRNAs regulate plant development

...that may be regulated by ARF17. These changes were correlated with dramatic development defects in leaves, roots, and flowers, showing that microRNA-mediated regulation of ARF17 is essential for normal plant development. Bonnie Bartel notes that "we have known for several years now that microRNAs regulate gene...

Arthritis: What Wnt wrong?

...addition, strong Wnt-7b expression most frequently correlated with areas of high inflammation. The authors also examined whether inflammatory cytokines were produced in primary cartilage and synovial cells from arthritic versus normal joints. While OA cells did not differ from controls, primary RA cells produc...
