Epstein-Barr virus may be associated with multiple sclerosis

...hree people with blood samples but without MS were matched to each MS patient by age, sex and date of blood collection. The blood samples of all participants were then analyzed to determine the levels of antibodies against the Epstein-Barr virus. Measuring antibodies, proteins produced by the body to fight ...

World Trade Center identifications pushed forensic DNA technology

...roup used up to 16 markers. If sufficient markers matched known DNA samples, then there was an identification. However, to do any matching, analysts needed DNA samples from the missing individuals including toothbrush, hairbrush and razor samples and DNA samples from close relatives. The New York City Pol...

For the first time: Longevity modulated without disrupting life-sustaining function

...tion when a single receptor on the cell surface is matched to an insulin-like signal. "If you were to interfere with insulin signaling in humans in order to prolong life, you would induce diabetes right away," cautioned graduate student and first author Suzanne Wolff. When this pathway had been clipped in ...

Intimate kissing quadruples risk of meningitis in teenagers

...y 1999 to June 2000. Each case was compared with a matched control. Blood samples and nose and throat swabs were taken and data on potential risk factors were gathered by confidential interview. Intimate kissing with multiple partners, a history of preceding illness, and being a student conferred higher ris...

Cuttlefish masters of disguise despite colorblindness

... placed on substrates whose color intensities were matched to the Sepia visual system, suggesting that these checkerboards appeared to their eyes as uniform backgrounds. However, their results showed that cuttlefish were able to detect contrast differences of at least 15%, which Mäthger and her colleagues su...

Spousal illness can trigger partner death

...tia, and the timing of such interventions might be matched to the riskiest times for caregivers, for example, just after the hospitalization of the spouse." "It seems clear that a person's illness or death can have health consequences for others in his or her social network," Christakis says. "This means th...

New influenza vaccine takes weeks to mass produce

First SCID gene chip to be introduced at Academy meeting on immunodeficiencies

...ate for bone marrow transplantation for unrelated, matched donors and treatments using gene therapy. In addi...esearch published Feb. 1, 2006 in JAMA showing how matched unrelated donors provided better engraftment, immune reconstitution and survival for SCIDpatients un...

A surprising pair of proteins help make healthy eggs

...ientists arrived at their findings by creating two matched rat cell lines of ovarian granulosa cell origin. In the experimental line, the level of TAF4b was increased. Berkeley researchers compared these lines and were able to identify the cooperative role of TAF4b and c-Jun, as well as the activation of the...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

...otube surfaces and was subsequently hybridized, or matched to its complementary DNA. "We have found that electrical measurement of carbon nanotube devices produce sensor results that are comparable to state-of-the-art optical techniques," Star said. He added, "The applications of our method for detection o...

Infant transplant patients resist infections that kill adult AIDS patients

...ents 1-10 years post transplant and healthy people matched to the transplant patients by age and gender. To compare T cell function, they measured the T cell response to select viral immunization. This comparison enabled them to see that infant heart transplant patients had more help from the immune system p...

Picking particles faster than one at a time

...the processed high-contrast particle images can be matched unambiguously with their originals in the more highly detailed, low-contrast micrograph. Some images may still remain problematic -- for example, some particles may be so close together they appear to be touching; in these cases, an additional proced...

New, unique microscope for nanotech

... of $354,000 from the National Science Foundation, matched by $151,714 from UC Davis. The confocal microscope allows three-dimensional imaging of samples, such as cells, and picks up structures tagged with fluorescent dyes. Instead of cutting a sample into thin slices, a researcher can focus through the ent...

New research examines genetics of successful aging

...f 100 young adults, aged 18-25 years old, who were matched for sex, race, ethnicity and geographic location. Specifically, Dr. Zubenko and his research team attempted to identify specific genetic sequences present in older individuals that may be linked to reaching older ages with preserved cognitive abilit...

Womb needed for proper brain development

...weeks gestation and at birth in other studies to a matched group of 38 full-term infants. Measurements taken from the ultrasounds showed that certain frontal portions of the brains of the premature babies were comparable at birth to the brains of babies still in utero at that stage of gestation. However, af...

Same-sex mating by fungi spawned infection outbreak, evidence suggests

...to identical isolates in Australia. The major form matched a sample taken from an infected person in Seattle 30 years ago and another collected from a Eucalyptus tree in San Francisco in 1992. What's more, the Canadian strains shared approximately half of their genetic makeup, suggesting that the two might ...

Envisat radar surveillance protects endangered prehistoric fish

...he Argos system operator. Argos positions are then matched with radar echoes to discriminate illegal vessels, whose locations are then sent for action to French Navy patrol boats." The system has been operational since February 2004. It had an early success on 25 June 2004 when French Navy patrol boat Alba...

Researchers develop new method for studying 'mental time travel'

...ity as they recalled the images to see how well it matched the patterns associated with the initial viewing of the images. The researchers found that patterns of brain activity for specific categories, such as faces, started to emerge approximately five seconds before subjects recalled items from that catego...

War on terror meets war on cancer

...r the isotope ratio of the metabolite more closely matched the food that the individual consumed or the proteins already in the individual's body. If it is the latter, then it means that the individual is basically in a starvation state, living off of their stored proteins." Finding Hidden but Aggressive ...

NRL scientists detect 'milky sea' phenomena

...ff the Somali coast. The boundaries of the feature matched closely with a surface ship's reported entry and exit of the brightly glowing waters. Although such observations cannot be fully explained based on the known features of any light-emitting organism, these so-called "milky seas" are hypothesized to ...
