Job burnout can severely compromise heart health Posted: 12 Mar 2013 10:49 AM PDT Dr. Sharon Toker of Tel Aviv University has found a link between job burnout and coronary heart disease (CHD), the buildup of plaque in the coronary arteries that leads to angina and heart attacks. She says that her findings were more extreme than she expected and make burnout a stronger predictor of CHD than many other risk factors.

Therapeutic targets to alter inflammation, type 2 diabetes Posted: 12 Mar 2013 10:47 AM PDT New research reveals that B cells regulate obesity-associated inflammation and type 2 diabetes through two specific mechanisms. The study indicates the importance of continuing to explore B cells as a therapeutic target to treat these diseases.

A new study points to hospitals and long-term care facilities as settings in which this antibiotic-resistant strain is increasingly found.

Nose's unheralded neighbor: Maxillary sinuses allow noses to change shapes Posted: 12 Mar 2013 10:47 AM PDT The maxillary sinuses, those pouches on either side of the human nose, have a purpose after all: They act as cushions to allow noses to assume different shapes.

Skaters skin microbiomes get mixed up 'bouting' Posted: 12 Mar 2013 06:26 AM PDT The human skin is home to countless microorganisms that we can't see, but these microbes help define who we are. Our invisible passengers -- known as the skin microbiome -- contribute to our health in numerous ways including educating our immune system, protecting us from pathogens, and mediating skin disorders. In a new study, researchers investigated how the skin microbiome is transmitted between players in a contact sport, using roller derby as their model system.

Tickling the brain with magnetic stimulation improves memory in schizophrenia Posted: 12 Mar 2013 06:25 AM PDT Cognitive impairments are disabling for individuals with schizophrenia, and no satisfactory treatments currently exist. These impairments affect a wide range of cognition, including memory, attention, verbal and motor skills, and IQ. They appear in the earliest stages of the disease and disrupt or even prevent normal day-to-day functioning. Scientists are exploring a variety of strategies to reduce these impairments including "exercising the brain" with specially designed computer games and medications that might improve the function of brain circuits.

In a new study, scientists announce they have successfully sequenced the genome of a HeLa cell line. It provides a high-resolution genomic reference that reveals the striking differences between the HeLa genome and that of normal human cells. The study could improve the way HeLa cells are used to model human biology.

Needle-free vaccine for ear infections could also help reduce use of antibiotics Posted: 12 Mar 2013 06:22 AM PDT Researchers have found a new vaccine that both prevents and treats ear infections -- minus the needle jab. The vaccine -- which targets the bacteria responsible for half of all ear infections -- would be delivered through the skin via a small, dime-sized patch. The non-needle vaccine appears to pack a one-two punch against nontypeable Haemophilus influenzae (NTHI), attacking key parts of the bacteria's defenses and kick-starting the body's own immune system to help clear out the infection.

The surprising finding is a step towards understanding how these issues are related on a biological level, and will help doctors develop better treatment plans for patients dealing with fat or bone related pathologies.

Symptoms and care of irregular heartbeats differ by sex Posted: 11 Mar 2013 09:41 AM PDT Women with atrial fibrilation have more symptoms and lower quality of life than men with the same heart condition, according to an analysis of patients in a large national registry.

Evolution in the antibody factory: How immune cells are able to advance their own evolution Posted: 11 Mar 2013 09:39 AM PDT B cells play a crucial role in the defense of pathogens; they produce antibodies that help to combat intruders. They concurrently and continuously improve these molecules to more precisely recognize the pathogens. A team of scientists has discovered that during this process cells are able to advance their own evolution by increasing the selection pressure through previously-produced antibodies. The results are also significant for the development of new vaccination strategies.
