New imaging advance illuminates immune response in breathing lung

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ. The method allowed the team to observe, for the first time, both the live interaction of living cells in the context of their environment and the unfolding of events in the immune response to lung injury.

UCSB scientists demonstrate biomagnification of nanomaterials in simple food chain

(Santa Barbara, Calif.) –– An interdisciplinary team of researchers at UC Santa Barbara has produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain.

Acid suppressive medication may increase risk of pneumonia

Using acid suppressive medications, such as proton pump inhibitors and histamine2 receptor antagonists, may increase the risk of developing pneumonia, states an article in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj092129.pdf.

Electronic nose detects cancer

György Horvath from the University of Gothenburg, Sweden, and researchers from the University of Gävle and KTH Royal Institute of Technology have been able to confirm in tests that ovarian cancer tissue and healthy tissue smell different. The results were published recently in the journal Future Oncology.

Your genome in minutes: New technology could slash sequencing time

Scientists from Imperial College London are developing technology that could ultimately sequence a person's genome in mere minutes, at a fraction of the cost of current commercial techniques.

The researchers have patented an early prototype technology that they believe could lead to an ultrafast commercial DNA sequencing tool within ten years. Their work is described in a study published this month in the journal 'Nano Letters' and it is supported by the Wellcome Trust Translational Award and the Corrigan Foundation.

Scientists and physicians use genetic sequencing to identify and treat unknown disease

A collaborative team of scientists and physicians at the Medical College of Wisconsin and Children's Hospital of Wisconsin uses genetic sequencing to identify and treat an unknown disease.

For the one of the first times in medical history, researchers and physicians at The Medical College of Wisconsin and Children's Hospital of Wisconsin sequenced all the genes in a boy's DNA to identify a previously-unknown mutation. The team was able not only to identify the mutation, but to develop a treatment plan using a cord blood transplant, and stop the course of the disease.

Massachusetts physician groups improving patient experience, study finds

Most Massachusetts physician groups are using results from a statewide patient survey to help improve patient experiences, but a significant number are not making use of the information or are making relatively limited efforts, according to a new RAND Corporation study.

Although physician communication skills are thought to be crucial to patient-centered care, the physician groups studied rarely pursued strategies that focused on improving physicians' ability to communicate with patients, according to the study published online by the Journal of General Internal Medicine.

Johns Hopkins faculty highly value involvement of nearby urban community for improving research

A survey conducted by Johns Hopkins faculty found strong support among their peers for working more closely with the minority, inner-city community that surrounds the institution. Overall, 91 percent of faculty responders said closer ties make research more relevant to those it ultimately serves, and 87 percent said it improves the quality of research.

A possible cause -- and cure -- for genital cancer in horses?

Horses are prone to develop genital cancer, especially as they grow older. Male horses are more commonly affected than mares but both sexes suffer from the condition, which is extremely difficult to treat and may result in the animals' death. Because of the similarity of the disease to human genital cancer it seemed possible that a similar agent might be responsible.

Study finds food in early life affects fertility

The reproductive success of men and women is influenced by the food they receive at an early stage in life, according to new research by the University of Sheffield.

The research, which was published online this month (17 December 2010) in the journal Ecology, is the first study of its kind to show that early life food can have a serious influence on the life-long fertility of individuals.

Genome-wide hunt reveals links to abnormal rhythms behind sudden death, heart damage

A study among almost 50,000 people worldwide has identified DNA sequence variations linked with the heart's electrical rhythm in several surprising regions among 22 locations across the human genome. The variants were found by an international consortium, including Johns Hopkins researchers, and reported Nov. 14 in the Nature Genetics advance online publication.

Researchers discover human immune system has emergency backup plan

New research by scientists at the University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences reveals that the immune system has an effective backup plan to protect the body from infection when the "master regulator" of the body's innate immune system fails. The study appears in the December 19 online issue of the journal Nature Immunology.

Finnish researchers find a compound that prevents the growth of prostate cancer cells

Evidence pointing to the effects of monensin emerged in a project investigating the effects of nearly 5,000 drugs and micromolecules on the growth of prostate cancer cells. The project involved most of the drugs on the market today. Researchers found that small amounts of compounds – disulfiram (Antabus), thiram, tricostatin A, and monensin – can prevent the growth of prostate cancer cells without significant effects on the growth of the normal human prostate epithelial cells.

Despite damage, membrane protein structure can be seen using new X-ray technology, study reveals

Australian researchers have identified a way to measure the structure of membrane proteins despite being damaged when using X-ray Free-Electron Lasers (XFELs), a discovery that will help fast track the development of targeted drugs using emerging XFELs technology.

About 70% of drugs on the market today depend on the activity of membrane proteins, which are complex molecules that form the membranes of the cells in our body.

New research shows virus previously linked to chronic fatigue syndrome is a lab contaminant

A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV and that XMRV is present in the mouse genome.
