Scientists perform 'tricky' operation

...these, with no alternative drugs approved to treat resistant infections. "This is particularly an issue in developing countries, where the number of infected individuals is high and the access to public health services is low. "Now that researchers have access to a complete genome dataset the search for ...

Knocking out survival protein could aid leukemia treatment

...with an overabundance of the protein are also more resistant to anticancer drugs such as rituximab, which has revolutionized the treatment of certain chronic and acute leukemias. The study by researchers at the Ohio State University Comprehensive Cancer Center is published online in the journal Clinical Ca...

New research may overturn conventional wisdom on drug-resistant tuberculosis

...y TB is that the organism can become progressively resistant to standard therapy. This resistance was long thou...uded six patients who were initially infected with resistant TB and then became drug-susceptible or resistant to fewer drugs. In the remaining 32 patients, the i...

Will the plague pathogen become resistant to antibiotics?

... "When we identified the first Y. pestis strain resistant to multiple antibiotics, we warned that if this type of strain spreads or emerges again, it would pose a serious health problem" says co-author Elisabeth Carniel, head of the Yersinia Research Unit at the Institut Pasteur in Paris. "The discovery tha...

Key found to kill cystic fibrosis superbug

...ews/Microbiology. B. cenocepacia is a multi-drug resistant microorganism that lives in damp or wet places and causes rot in plants such as onions. While it rarely causes infection in healthy people, it can be fatal for people with cystic fibrosis (CF), an inherited disease where the lungs become clogged with...

A healthier start to a pig's life

...w fallen out of use, mainly due to the increase in resistant strains of bacteria. A radical solution has been found by using a lectin obtained from the red kidney bean plant. Lectins are proteins with the ability to bind cells together; typically red blood cells. The EUREKA Healthy Weaning project coordinato...

Leukemic cells find safe haven in bone marrow

...ALL cells from different patients became much more resistant to asparaginase when cultured on top of a layer of mesenchymal cells. In order to determine whether it was the high levels of asparagine released by mesenchymal cells that protected ALL cells from asparaginase, the St. Jude team repeated the experime...

Meat and two neutrons -- the key to a longer life

...al isotopes builds bodily components that are more resistant to the processes of ageing. The concept has been d...hought to produce bodily constituents and DNA more resistant to detrimental processes, like free radical attack. The isotopes replace atoms in susceptible bonds...

E. coli bacteria migrating between humans, chimps in Ugandan park

'Exercise pill' switches on gene that tells cells to burn fat

...ance (calories in, calories burned) makes the mice resistant to weight gain on a high fat diet. The hope, Dr. Evans told scientists attending Experimental Biology 2007 in Washington, DC, is that such metabolic trickery will lead to a new approach to new treatment and prevention of human metabolic syndrome. So...

New UD technology removes viruses from drinking water

... are far smaller than bacteria, highly mobile, and resistant to chlorination, which is the dominant disinfection method used in the United States, according to the researchers. Of all the inhabitants of the microbial world, viruses are the smallest--as tiny as 10 nanometers. According to the American Societ...

New approach could lower antibiotic requirements by 50 times

...s had slowly created a host of infections that are resistant to antibiotics. MRSA (Methicillin-resistant Staphylococcus aureus) for example is rapidly spreading through hospitals, affecting more than 8,000 people in the UK every year. MRSA infection can lead to septic shock and death. ...

Pharmaceutical compounds found in nation's fresh water

.... caffeine) persist through the human body and are resistant to conventional waste water treatment practices. They are often detected in aquatic environments such as lakes, rivers and ground water, which can receive direct inputs of treated waste water. "We don't know what toxicological effects these detec...

Widely used hepatitis B drug spurs HIV drug resistance

...io says viruses with this mutation are known to be resistant to lamivudine, better known as 3TC, a medication that prevents HIV replication and "is a cornerstone of most drug-combination therapies used to fight the immune system disease." Because lamivudine is in the same category of HIV therapies as another ...

Salmonella survives better in stomach due to altered DNA

...his type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics. Dutch researcher Armand Hermans found new genetic information in DNA of DT104 that might be involved in its survival and infection mechanism. This genetic information might also be involved in the increase in t...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

The discoverers of the unique mouse line that is resistant to cancer have begun to pin down how the process works and found that white blood cells in these mice overwhelm normal defenses of cancer cells. In a report in Cancer Immunity, a journal of the Academy of Cancer Immunology, posted on line today, Zhe...

ASU researchers test antibacterial effects of healing clays

...enic Staphylococcus aureus, including a multi-drug resistant variety. "The other clay actually helps the bacteria to grow," Haydel adds. What makes one clay kill bacteria, and the other promote growth? And why do most clays tested have no effect? Research like that being done by Williams and Haydel can answ...

Gladstone investigators identify a new protective action for the powerful anti-HIV factor, APOBEC3G

...re highly resistant. Scientists have known that resistant CD4 T cells, called "resting cells," are made up predominantly of CD4+ T cells that are in an inactive state, awaiting a stimulus to move into action. In these cells, A3G blocks HIV at an early step in its life cycle. However, when resting CD4 T cell...
