Dendrimers offers a new way to treat age-related macular degeneration, retinitis pigmentosa

Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A study by investigators at Mayo Clinic, Wayne State University and Johns Hopkins Medicine shows that steroids attached to the dendrimers target the damage-causing cells associated with neuroinflammation, leaving the rest of the eye unaffected and preserving vision.

Chronic fatigue syndrome may be reason behind many school absenteeism: Study

According to a new study one in 100 secondary school pupils could be missing classes because of chronic fatigue syndrome, also known as Myalgic Encephalomyelitis (ME). A study following 2,855 pupils at three schools, published in the online journal BMJ Open, found 28 missed school with chronic fatigue syndrome.

Alcohol intake linked to unsafe sex

It is known that unprotected sexual intercourse is the most common cause of HIV infection and finding ways to prevent unsafe sex is a major goal of public health efforts to prevent HIV/AIDS. It has not been clear whether unsafe sex associated with alcohol use actually led to HIV infection, or whether certain personality traits, such as sensation-seeking or risky behavior, led to both alcohol use and unsafe sex.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Chemical disruption to key interaction shown to limit metastasis in test mice

Finding ways to counteract or disrupt the invasive nature of cancer cells, called "metastasis," has been a long-term goal of cancer researchers. Now, researchers at Moffitt Cancer Center in Tampa, Fla., have identified an interactive pathway that regulates metastases in some cancers that may be vulnerable to chemical targeting in order to prevent cancer cell proliferation and tumor growth.

Textile cushions with smart sensor systems for persons confined to bed or wheelchair

Anyone confined to a wheelchair or a bed has to deal with numerous complications. Frequently, they suffer from bedsores or decubitus ulcers as physicians call them. Bony prominences, such as the sacrum, coccyx and ischium, are especially endangered spots. Unrelieved pressure can lead to tissue necrosis. Damage can extend into the periosteum and, at the worst, into bones themselves.
