Genes and genius: Researchers confirm association between gene and intelligence

.... In this multi-center study, people who have been treated for alcohol dependence and members of their families provide DNA samples to researchers, who isolated DNA regions related to alcohol abuse and dependence, as well as a variety of other outcomes. Some of the participants in the study also took the ...

Major link in brain-obesity puzzle found

...gulate eating. What’s more, the mice that were treated to make extra SH2B1 didn’t become obese or lose their ability to respond to leptin signals even after being fed a high-fat diet that caused those effects in other mice. “Obesity, whether in mice or humans, is the product of an altered balance bet...

Pharmaceutical compounds found in nation's fresh water

...d ground water, which can receive direct inputs of treated waste water. "We don't know what toxicological effects these detectable concentrations of pharmaceuticals pose, although typical concentrations in one liter of ground water are usually much lower than a typical human therapeutic dose," says lead ...

Stress hormones may play new role in speeding up cancer growth

...requently among people of Chinese descent. They treated Glaser's cell line with norepinephrine and, as predicted, the cells all produced MMP-2, MMP-9 and VEGF. This showed that the receptors for this hormone were present on cells in Glaser's cell line, but that might have been just a laboratory aberration...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

...nsported to the rest of the body. Patients were treated with drugs which encourage reverse remodelling of the heart, prevent atrophy and prevent the heart from shrinking beyond its desirable size. The drugs used were lisinopril, carvedilol, spironolactone and losartan in the first stage of treatment and b...

Microbes compete with animals for food by making it stink

... used newly thawed fish, fish soaked in antibiotic treated water and fish aged without antibiotics. They found that both freshly thawed bait and aged, antibiotic-treated bait attracted animals more frequently than traps containing aged, microbe-laden menhaden. Then researchers extracted various compounds f...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

Monoclonal antibody reduces exacerbations in asthmatics

Patients with symptomatic moderate asthma who were treated with anti-tumor necrosis factor alpha, an anti-inflammatory monoclonal antibody, experienced significantly fewer disease exacerbations than individuals taking a placebo. This research appears in the first issue for October 2006 of the American Journ...

Backache beaten by good vibrations?

...ica is an extremely common and disabling condition treated by physiotherapists. "The pain caused by inflammation of lumbar nerve roots could potentially be reduced with the application of TU, a form of electrotherapy commonly used by physiotherapists to accelerate the resolution of the inflammatory proces...

Proteins may predict lung transplant rejection

...ion. Because this study looked back at patients treated years ago, the researchers could look for differences between patients who subsequently suffered chronic lung rejection and those who did not. The researchers combined proteomics (the study of proteins), the latest in mass spectrometry technology ...

Mutant gene causes severe kidney disease in infants

Preliminary study finds holographic imaging system promising for cancer treatment planning

... prepared using the Perspecta. Fourteen previously treated plans were replanned using Perspecta. The plans were then reviewed by four physicians who were unaware of what planning device was used. All the reviewers felt that the Perspecta device allowed better appreciation of 3D relationships of anatomic...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

...calized to skin and soft tissue and usually can be treated effectively. CA-MRSA strains have enhanced virulence, meaning they can infect otherwise healthy people. One of the biggest problems with CA-MRSA skin infections is that they spread rapidly and have the potential to cause illness much more severe than...

Math model predicts cancer behavior

...cur," Quaranta said. "Does that patient need to be treated very aggressively, or not so aggressively"" Today, a tumor's size and shape are evaluated, but they can be poor indicators of invasive potential: a very small tumor can be highly invasive. Even "molecular signatures" ?profiles of molecules that sug...

New approach to BSE successful in lab

...on average after 165 days, the mice which had been treated lived appreciably longer,?is how Professor Kretschmar summarises the results. BSE-resistant cattle" It varied how much longer they lived: if only a few cells could produce siRNAs, the mice died at almost the same time as the control mice, i.e. ...

Antibiotic treats lymphoma of the eye

...hout causing the same toxic side-effects. Patients treated with doxycycline had a 66% rate of disease-free survival. "Our prospective trial revealed that doxycycline is a fast, safe, and active treatment for OAL, both at initial diagnosis and at relapse," the authors write. In an accompanying editorial, ...

Einstein researchers demonstrate a novel approach to treating AIDS

Scientists show drug can counteract muscular dystrophy in mice

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

... with chlamydia each year. Chlamydia can be easily treated and cured with antibiotics. However, bacteria often develop resistance to antibiotics, meaning that new ones must be continually discovered. Moreover, an inhibitor to L,L-diaminopimelate aminotransferase would be very specific for Chlamydia since thi...
