Combination laser and ointment therapy effective in treating vitiligo

Patients with vitiligo, a skin disorder characterized by patches of white, or de-pigmented skin, had better repigmentation of these patches when they were treated with a combination of laser therapy and tacrolimus ointment than patients treated with laser therapy alone. Vitiligo is a skin pigmentation disorder that affects one percent to two percent of people worldwide. Patients with vitiligo develop white patches on their skin, referred to as ”lesions.”

World’s most powerful MRI for decoding the human brain

The University of Illinois at Chicago unveiled today the world’s most powerful magnetic resonance imaging machine for human studies, capable of imaging not just the anatomy but metabolism within the brain. This advanced technology ushers in a new age of metabolic imaging that will help researchers understand the workings of the human brain, detect diseases before their clinical signs appear, develop targeted drug therapies for illnesses like stroke and provide a better understanding of learning disabilities.

Wastewater could treat itself, power city

The energy stored in Toronto’s municipal wastewater could be harnessed to run water treatment facilities and contribute power to the city grid, says new U of T research. The study, published in the August issue of the Journal of Energy Engineering, is the first to measure the energy content of the raw municipal wastewater in the Ashbridges Bay, North Toronto, Highland Creek and Humber plants. The research revealed that the wastewater contained enough organic material to potentially produce 113 megawatts of electricity or close to 990 million kilowatt hours a year.

Fibromyalgia prohibits sufferers from breast-feeding

New mothers with fibromyalgia (FM) face multiple barriers to breast-feeding their babies, according to a new study. For the study, researchers analyzed the written stories and tape-recorded interviews of nine mothers with FM, ranging in age from 26 to 36. All had given birth to at least one child before being diagnosed with FM, a chronic disorder characterized by widespread pain and fatigue. Because there is no cure, patients often undergo physical therapy, counseling and medication to alleviate their symptoms.

Heavy Metal Rocks Plant Cells too

Heavy metals can trigger widely varying stress reactions in plants. A team at the Campus Vienna Biocenter was now able to provide evidence for this in a research funded by the Austrian Science Fund (FWF). The results, now awaiting publication, are an important basis to comprehend how plants cope with an increase in heavy metal concentrations in the soil – and how these abilities can be profitably utilised.

Water and methane maps overlap on Mars: a new clue?

Recent analyses of ESA’s Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap. This result, from data obtained by the Planetary Fourier Spectrometer (PFS), gives a boost to understanding of geological and atmospheric processes on Mars, and provides important new hints to evaluate the hypothesis of present life on the Red Planet.

Vanilla may have a future in sickle cell treatment

In addition to its popular role in flavoring ice cream, fudge and cake frosting, vanilla may have a future use as a medicine. Recent laboratory research has strengthened the possibility that a form of vanilla may become a drug to treat sickle cell disease. After specially bred mice received a compound that turns into vanilla in the body, they survived five times longer than mice that did not receive the chemical. All the mice had been subjected to low oxygen pressure, a condition that causes their red blood cells to form the hazardous sickle shape.

HIV Dementia Mechanism Discovered

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have discovered a key mechanism in the brains of people with human immunodeficiency virus (HIV) dementia. The study is the first to document decreases in the neurotransmitter dopamine in those with the condition, and may lead to new, more effective therapies. HIV dementia is a type of cognitive decline that is more common in the later stages of HIV infection.

Targeted therapy knocks out pediatric brain cancer in mice

Scientists have identified what may be the first nontoxic treatment for a subset of medulloblastoma, the most common type of malignant pediatric brain tumor. The finding is encouraging in that such precise, targeted therapies may someday replace traditional treatments that can have overwhelmingly negative side effects for pediatric cancer patients. ”Therapy for pediatric cancers of the central nervous system has not improved significantly in the last three decades. This is partly due to the absence of adequate model systems for testing novel therapies.”

NASA Airborne Observatory Sees Stars for First Time

For the first time, scientists have peered at the stars using the newly installed telescope aboard NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), the largest airborne observatory in the world. During the night of Aug. 18-19 in its first ground-based ‘on-sky test,’ the telescope was pointed at the star Polaris. A crisp white dot appeared on astronomers’ computer screens inside the aircraft, demonstrating that the telescope’s basic optical, mechanical and software systems all are functioning properly. ”This is an important milestone from an engineering perspective, because all the telescope subsystems have been integrated on the aircraft for the first time, and it substantiates all the engineering design and interface work performed on both sides of the Atlantic.”

Anti-inflammatory strategy for cancer therapy identified

A new strategy for cancer therapy, which converts the tumor-promoting effect of the immune system’s inflammatory response into a cancer-killing outcome, is suggested in research findings by investigators in San Diego. The findings provide new insight into the immune system’s response to inflammation, the connection between inflammation and malignancy, and how the delicate balance between cancer promotion and inhibition can be manipulated in the patient’s favor.

Talking to your dying child

For the first time a major study is now being presented in which parents of children who died of cancer were given the opportunity to talk about their experiences. The findings are being published in several acclaimed articles and a doctoral dissertation at Karolinska Institutet in Sweden. All parents of children who died of cancer in Sweden between 1992 and 1997 were contacted four to nine years after the death of their child. One part of the study based on the massive material takes up the question of whether the parents had talked with their severely ill child about death. None of the 147 parents who had done so regretted doing so. On the other hand, 69 (27%) of the 258 parents who had not spoken with their child about death later regretted not having done so, most of them because they had realized that their child had in fact understood that he/she was dying.

Nanotechnology may give plastic solar cells a boost

Until now, lightweight plastic solar cells have remained elusive. During the last decade, scientists have struggled to substitute polymers for the expensive, but effective crystalline materials such as silicon, a traditional solar cell material. These attempts produced solar cells with poor efficiencies at converting light into electricity. Researchers now hope to develop an improved polymer solar cell using nanomaterial additives. Specifically, a team in Rhose Island will use a thin polymer film that can be rolled out in sheets. The film will contain nanoscale pieces of semiconductor material and single-walled carbon nanotubes to maximize energy conversion.

Corneal thickness significantly impacts glaucoma treatment

Researchers have demonstrated the significance of central corneal thickness (CCT) on the clinical management of patients with glaucoma and those suspected to have glaucoma. While confirming previous research about the relevance of CCT in glaucoma management, this study represents one of the first attempts to determine exactly how great an impact CCT has on a patient’s intraocular pressure (IOP), fluid build-up inside the eye that is a glaucoma risk factor. Results found that CCT affected more than half of the patients in the study.
