Brain inflammation may be friend, not foe, for Alzheimer's patients

...e of inflammation in Alzheimer’s disease. O’Banion notes that some studies have found that taking medications to squelch inflammation, such non-steroidal anti-inflammatory drugs or NSAIDs, might help reduce a person’s chances of getting Alzheimer’s disease, while other studies, including a study of more th...

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

...ein-coding regions of DNA where genes reside, Yauk notes that previous studies 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 interfer...

Studies to find better ways to preserve human eggs, ovarian tissue under way

.... As pieces of a puzzle come together, Dr. Song notes scientists already are developing methods to stimulate ovarian tissue to produce eggs outside the body, a process that could also make in vitro fertilization a lot more affordable. Others are looking for ways to ensure there are no cancer germ cells ...

Newly found sensing system enables certain bacteria to resist human immune defenses

...s to bolster our antimicrobial treatment options,” notes NIAID Director Anthony S. Fauci, M.D. Led by Michael Otto, Ph.D., of NIAID’s Rocky Mountain Laboratories (RML), the scientists used the gram-positive bacterium Staphylococcus epidermidis to study its response to a specific human AMP, human beta de...

Genetic factors are linked to fever following smallpox vaccination

... the variations in host responses to vaccines, and notes that further studies will need to replicate these findings, and to test other vaccines. Both Drs. Stanley and Crowe mention that the results may have important implications when it comes to the future goal of identifying individuals at risk for feve...

Exploring the dark matter of the genome

...ter understanding of genome functions. Karpen notes that one intensively studied and puzzling problem in chromosome biology will benefit enormously from the new findings: epigenetics -- the inheritance of traits and genetic information as controlled by proteins associated with the chromosomes, rather ...

Researchers discover 'acquired' DNA key to certain bacterial infection

...100,000 persons may be affected. However, CDC also notes that the bacterium’s resistance to antibiotics – already a problem – may be increasing. In contrast, the incidence of lung infection in patients with chronic lung diseases and cystic fibrosis is increasing. Understanding the mechanism by how M. av...

Helping chlorine-eating bacteria clean up toxic waste

...ichardson, who grew up in the Hudson River Valley, notes that such pollutants are common in the river's harbors. "There are still thousands of sites around the country that need to be cleaned up," she said. "Ithaca has three or four, and that's not atypical."...

Mice with a migraine show signs of brain damage

...ocus should be on prevention,?said Nedergaard, who notes that by the time a person feels pain or notices a visual disturbance, the changes to the brain are already well underway. To make the finding, the team used a sophisticated laser system known as two-photon imaging to look at the activity of live c...

The sound of proteins

...hat appear more frequently transcribed into longer notes than those which appear less often. Individual ami...r chord, but they can be distinguished because the notes in the chord are arranged differently. This means the resulting music has a 20 note range spanning o...

Tissue engineered scaffolding allows reproduction of cartilage tissue

...zing cartilage in the scaffold structure in vivo," notes study author Dr. Byoung-Hyun Min. "Cell-derived scaffolding may hold great promise for the future. A variety of applications are possible for the engineering of cartilage tissue as the shape and porosity can be altered to suit the type of tissue requ...

DNA-damage test could aid drug development

...ld be closer to in vivo human than in vivo mouse," notes Shuga. "That premise will be tested in coming years as new systems become available." ...

Dinosaur hearing, listening to muscle noise, quieter cubicles

... Florida Everglades. Blomberg ( npc@nonoise.org ) notes that noise in national parks follows the same cons...Smith says, trumpets are not supposed to play high notes around the frequency range of 2 kHz, according to some acoustics textbooks, yet some skilled trumpet...

Herpes infection may be symbiotic, help beat back some bacteria

...findings suggest that we need to start." Virgin notes that human and mouse herpes viruses are genetically very closely related. The similarity strongly suggests that modern herpes viruses are likely descended from herpes viruses that infected evolutionary ancestors common to both mice and humans. "Th...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

...ively promoting voluntary household smoking bans," notes Dr. Shelley. The data also confirm that among Asian Americans the most at risk are the least acculturated non-English speaking immigrants. Before the New York City Clean Indoor Air Act of 2003, second-hand smoke exposure among this immigrant Ch...

Sandia researchers take new approach to studying how cells respond to pathogens

...immune response to highly pathogenic organisms. He notes the integrated platform, biological reagents and computational models developed under this project have applicability beyond infectious disease research. These technologies can also be used for studying cellular signaling involved in diseases such as...

Discovery could lead to better control of hemorrhagic fever viruses

...lls makes them less susceptible to infection. Choe notes that New World hemorrhagic fever outbreaks mostly occur in poor rural areas, where people are often deficient in micronutrients, including iron, possibly predisposing them to more severe infection when exposed to the rodents that carry the viruses. ...

Study examines risk of soft tissue sarcomas in hereditary retinoblastoma survivors

...etinoblastoma in the last several decades, and she notes that some of these findings may be applicable only to patients who received treatments that are no longer used. "Improved treatment can be expected to reduce the incidence of soft tissue (and bone) sarcomas associated with radiation," Meadows writes....

NIAID DNA vaccine for H5N1 avian influenza enters human trial

Columbia scientists determine 3-dimensional structure of cell's 'fuel gauge'

...using potentially toxic side effects. However, he notes that this development in understanding the atomic resolution structure of the protein provides researchers a powerful new tool for the design of useful therapeutics. ...
