Gene therapy for blindness clears hurdle in mice

... detailed in an upcoming issue of Vision Research, involves injecting the eye with a bit of genetic material called interfering RNA, which helps disable the gene. Normally the gene is essential for healthy eyesight, but mutated versions of it are passed from generation to generation in some families and ca...

Scientists to track impact of Asian dust and pollution on clouds, weather, climate change

...ense of smell, since the olfactory system not only involves complex neural circuits but also has a behavioral component. "The perception of smell is quite complex," Ehlers said. "The brain can decode thousands of smells that enter the nose, discriminating even the slightest scent and often conjuring up viv...

Common algae helps illustrate mammalian brain electrical circuitry

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...ue of Analytical Chemistry. The technology involves embedding fluorescent quantum dots and magnetic iron oxide nanoparticles inside the beads to create dual-modality magneto-optical beads. Nie and Sathe synthesize the quantum dots in different colors by varying their size, giving the beads a unique op...

Cancer researchers add spice to research against rare neuromuscular disease

...neurons. This smothers CBP's normal activity which involves turning on another molecule known as VEGF, a growth factor that is crucial for life and essential to the health of motor neurons. Chang's team found that ASC-J9 breaks up the clumps by separating the androgen receptor from some of its helper molec...

Computer imaging assists with facial reconstructive surgery

A new calibration technique that involves measuring the distance between the upper ear and chin in photographs could help facial plastic surgeons use computer imaging software to achieve aesthetic harmony in their patients, according to a report in the March/April issue of Archives of Facial...

Parasite infection may benefit MS patients

...ients showed an overall increase in EDSS. Since MS involves an inflammatory response associated with the production of certain regulatory proteins known as cytokines, the number of cells producing cytokine suppressants was measured and found to be significantly higher in infected patients. The authors sugg...

Batten down the hatches against HIV

A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation" into the corresponding, disease-related protein. A stumbling block has been the efficient and targeted delivery of RNA into the cells. Researchers led by ...

Using dental X-rays to detect osteoporosis

...graphs to detect patients at risk for osteoporosis involves no extra radiation and almost no extra cost, while undetected osteoporotic patients can incur bone fractures and suffer from other problems, reducing the quality of life. By analyzing a small area depicting the trabecular bone on the ordinary dent...

Scientists unravel clue in cortisol production

...rning cholesterol into the stress hormone cortisol involves many reactions and begins when the hypothalamus sends a signal to the adrenal glands. Proteins then flood into the nucleus to bind to the DNA, creating the gene CYP 17. What happens next is well understood; CYP 17, along with a battery of other enzym...

New hereditary breast cancer gene discovered

...ncer. Saethre-Chotzen is a syndrome that primarily involves malformations of the skull, face, hands, and feet. The syndrome is caused by mutations in a gene called TWIST1. "Our findings show that women with this syndrome run a nearly twenty times greater risk of contracting breast cancer than expected. Mo...

Targeting tumors the natural way

...ssling. Cell recognition in living systems instead involves binding agents that attach only weakly to any single target receptor, and thus stick to cells only when several receptors are displayed together. These weak "multivalent" interactions cut down on cases of mistaken identity, because if the agent conta...

Cellulose nanocrystal research could lead to new vaccines, computer inks

...culties to the people using them. A typical remedy involves converting the nanocrystals to a powder. This has risks as well, as the powder can be a serious health hazard if inhaled. The ink jet printing allows for a safe method of deposition of the nanocrystals. ...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

...ty of Toronto, said: "Most human leukemia research involves studying a patient's diseased cells or a cell line grown from those cells. However, since cancer takes many months or years to develop, just studying the cells at the end of the process does not let you know what the series of changes were that cause...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

...t to process information. "In general, learning involves neuronal excitation in certain parts of the brain," said Garner. "For example, caffeine, which is a stimulant, can make us more attentive and aware, and enhance learning. Conversely, alcohol or sedatives impair our ability to learn." But as any ov...

Genes and genius: Researchers confirm association between gene and intelligence

...between the gene, CHRM2, and performance IQ, which involves a person's ability to organize things logically. "This is not a gene FOR intelligence," says Danielle M. Dick, Ph.D., assistant professor of psychiatry and lead author on the study. "It's a gene that's involved in some kinds of brain processing, ...

MIT bioengineer advances survival, promise of adult stem cells

...bone injuries. Current treatment for such patients involves replacing the bone with either cadaver bone or, more commonly, a piece of the patient's hip bone. Ideally, surgeons would like to be able to aspirate bone marrow from the hip, which is a much less painful and invasive process than removing bone, a...

MIT device draws cells close -- but not too close -- together

The technology involves collaboration between the Mayfield Clinic, one of the nation's leading physician organizations for clinical care, education, and research of the spine and brain, and UC Radiology, which purchased the BrainLAB planning station hardware. Both physician...

Cloned mice created from fully differentiated cells, a milestone in cloning research

... transfer (SCNT), the scientific term for cloning, involves creating an embryo by using a nucleus that's been removed from a somatic cell ?any cell other than a reproductive cell ?and transferring it into an unfertilized egg that has had its chromosomes removed. Because the resulting new embryo contains the e...
