Key found to kill cystic fibrosis superbug

...e the lungs become clogged with thick mucus, often leading to chronic respiratory infections. The team of researchers has identified a weakness in the armour that protects the B. cenocepacia bacterium from the effects of antibiotics. They hypothesize that preventing the synthesis of a key sugar required ...

Pregnancy hormone key to repairing nerve cell damage

...mune system attacks the myelin surrounding nerves, leading to progressive loss of sensation and movement. MS affects approximately 2.5 million people worldwide and Canadians have one of the highest rates of the disease in the world. "It is thought that during pregnancy, women's immune systems no longer de...

New protein implicated in autism

...ver detected in their healthy immediate relatives, leading to the suggestion that defects in CADPS2 function might predispose individuals to develop autism. ...

A healthier start to a pig's life

...fections, restricting their growth rate; and often leading to losses of 10% or more. The antibiotics used routinely for many years to control these rapidly-spreading infections have now fallen out of use, mainly due to the increase in resistant strains of bacteria. A radical solution has been found by usin...

Microfluidic chip helps solve cellular mating puzzle

...s a projection toward the source of the pheromone, leading to a cellular merger. This mating process is regulated by proteins inside the cell called mitogen-activated protein kinases, or MAPKs, through a chain of chemical reactions. First, sensors on the surface of a yeast cell pick up signals that a mati...

Baby fish 'smell their way home'

...cluded that smell was probably the dominant factor leading the babies home. "Every reef gives off its own unique chemical signature, a rich mixture of the proteins and amino acids emitted by corals, all the plankton and mucus from its life. We think baby fish can pick this up and distinguish it from othe...

Army research mission focused on autism

...alth and behavior vary widely from mild to severe, leading to their general classification as Autism Spectrum Disorders. About 10 percent of individuals with ASD develop autism secondary to a known genetic disorder. The cause of ASD is not certain; however, parents of ASD children have been playing a signifi...

How T lymphocytes attack

...the antigen was essential to in-depth penetration, leading to effective tumour elimination. These results were validated in two types of experimental tumour generated from two lines of cancer cells. It is now up to the clinicians to verify whether the in-depth infiltration of T lymphocytes could consti...

Satellites shed light on global warming

...hat populate the oceans in huge numbers and play a leading role in the global carbon cycle and the primary production of nutrients. Current research is investigating these relationships by exploiting the powerful union of multiple views of the ocean made possible by different instruments like those in th...

Fruit fly gene research may shed light on human disease processes

...lished in this month's issue of Current Biology, a leading biology journal. Human females have two X chromosomes in every cell, while human males have an X and a Y chromosome. "Just as in mammals, flies have two 'sex' chromosomes, a X and a Y" he explains. "However, in the fly, unlike in humans, the Y ch...

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

...aused by an extra copy of chromosome 21. It is the leading cause of mental retardation in the country, and it is also associated with childhood heart disease, leukemia and early onset Alzheimer’s disease. The researchers used a mouse model of Down syndrome for their study in which about 150 genes are triplic...

Scientists reveal structure of gateways to gene control

...gh explains. The paper by Pugh's team marks the leading edge of a new wave of anticipated discoveries about gene regulation, made possible by recently developed laboratory equipment for high-volume, or massively parallel, DNA sequencing. "Traditional DNA sequencing methods processed one DNA strand at a t...

New insights into autoimmunity and depression

...intriguing aspect of the present study," notes its leading author, Yehuda Shoenfeld, M.D., while emphasizing the need for further investigation through large-scale clinical studies. "Elucidating the mechanisms by which anti-ribosomal P induces behavioral changes may lead to novel therapeutic advances for SL...

Groundbreaking Canadian asthma study

...or irritant, the airway smooth muscle may contract leading to airway narrowing and breathing difficulties. Asthma currently affects more than 2 million people in Canada....

100 percent juices found as beneficial to health as fruits and vegetables

...en and adults, following guidelines established by leading health authorities. Taylor also points to a large epidemiological study, published in the September 2006 issue of the Journal of Medicine, which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a re...

Major link in brain-obesity puzzle found

...H2B1 in the brain trumps its action in fat tissue, leading to the development of obesity in mice that lack SH2B1 in both locations. Rui and his team now hope to explore SH2B1's role in the brain and body even further, and hope to translate their findings into clinical research involving humans. They hope...

Music genes and musical geniuses

...f Music, to be held in Bologna, May 20 to 22, with leading scientists currently involved in researching the mysteries of music, invited to explain their recent findings to the audience. The meeting is organized by the European Genetics Foundation and the Fondazione Pierfranco e Luisa Mariani, in collaboratio...

Widely used hepatitis B drug spurs HIV drug resistance

...ntecavir, first marketed in March 2005, has been a leading treatment for chronic forms of hepatitis B, which can be fatal to almost a quarter of those infected if it is left untreated. The drug's label information currently states that is has no clinical effects on HIV. According to Thio, some co-infect...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...ssible to simulate the cell cycle -- the processes leading to cell division. They have demonstrated that the new mathematical models and numerical algorithms provide powerful tools for studying the complex processes going on inside living cells. Biologist John Tyson, who studies the cell cycle, is a leader ...

Chronic pain up almost 40 percent among US workers in past decade

... opt to go to their jobs rather than call in sick, leading to a growing trend of presenteeism ?a negative impact on work despite being physically present at the job. These data, released today, are from a 2006 national survey conducted by Harris Interactive® on "Pain in the Workplace" ( www.painandwork.com )...
