Breast-fed babies may have healthy gut microbial population

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens.

Detrimental effect of tetracycline on male reproductive function, sperm viability of pseudoscorpions

In a paper published today in Nature's open access journal Scientific Reports, researchers at the University of Nevada, Reno report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

First idiothetic memory study in humans

It's night time. The light suddenly goes out in the room where you are. At the same time you hear somebody crying: "Fire!". You bolt. Will you be able to find your way out in total darkness? Most likely, yes - if the room is somewhat familiar to you and not too big. Escape will be possible because of idiothetic memory, one of two types of human spatial memory. This type of memory relies not on visual information, but on information coming from the body. In the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw it was investigated whether this type of memory can be affected by age.

UAB researcher wins HudsonAlpha Prize for work on sickle cell and related blood disorders

Tim Townes, Ph.D., University of Alabama at Birmingham, was awarded the HudsonAlpha Prize for his work on sickle cell and related blood disorders. The $20,000 monetary award acknowledges exceptional talent, dedication and discovery by Alabama's best and brightest researchers.

Researchers use Moffitt's Total Cancer Care to create designer lymph nodes

Researchers at Moffitt Cancer Center are in the first phase of creating "designer lymph nodes." Designer lymph nodes are built with specialized gene-modified cells that are injected into patients and produce a pre-planned immunologic response for cancer patients locally and then throughout their bodies. The researchers are examining a cancer vaccine "boosting" effect of the manufactured lymph nodes in patients with advanced melanoma.

Study highlights role of cellular forces in progression of cardiovascular disease

Clogging of pipes leading to the heart is the planet's number one killer. Surgeons can act as medical plumbers to repair some blockages, but we don't fully understand how this living organ deteriorates or repairs itself over time.

Researchers discover gene for new form of intellectual disability

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.

Researchers define structure of key part of human obesity receptor

Medical researchers at the University of Sheffield have defined the structure of a key part of the human obesity receptor- an essential factor in the regulation of body fat- which could help provide new treatments for the complications of obesity and anorexia.

Drug-resistant malaria might be spreading in Africa, study suggests

A strain of malaria that is resistant to artemether, the main ingredient in Coartem, a widely used drug to treat the disease, may be spreading in Africa, according to a study published Thursday in Malaria Journal, Bloomberg Businessweek reports.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Smoking during pregnancy may increase risk of autism in children

Women who smoke in pregnancy may be more likely to have a child with high-functioning autism, such as Asperger's Disorder, according to preliminary findings from a study by researchers involved in the U.S. autism surveillance program of the Centers for Disease Control and Prevention.

Kras gene triggers metabolic changes that fuel cancer cells

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.

Study explores resilin-like materials for vocal fold disorders

A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.

Rochester researcher to continue MS study

A Rochester, New York, researcher will receive a $263,622 grant to continue his study of injury to brain cell connections (synapses) in multiple sclerosis (MS) through the American Brain Foundation (formerly the American Academy of Neurology Foundation) and the National Multiple Sclerosis Society Clinician-Scientist Development Award.

Study describes structure and function of the stratum corneum

A research team at Karolinska Institutet in Sweden has succeeded in describing the structure and function of the outermost layer of the skin - the stratum corneum - at a molecular level. This opens the way not only for the large-scale delivery of drugs via the skin, but also for a deeper understanding of skin diseases.

Combination of Velcade and Fasudil could treat NSCLC

A common cancer drug and a drug used for a rare condition affecting the heart could together treat an aggressive form of lung cancer called non-small cell lung cancer (NSCLC), according to a study published in Cell today.

Handheld plasma-producing device can instantly kill bacteria

A group of Chinese and Australian scientists, including CSIRO, have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant. The handheld plasma flashlight could be used in ambulance emergency calls, natural disaster sites, military combat operations and many other instances where treatment is required in remote locations.

Heart can regulate energy balance throughout the body

UT Southwestern Medical Center researchers have demonstrated for the first time that the heart can regulate energy balance throughout the body, a finding that may point to more effective treatments for obesity, diabetes, and heart disease.
