Health News: CDC 181 People infected with salmonella from contact with live poultry ♦ Working out in artificial gravity ♦ Supercharging stem cells to create new therapies

CDC: 181 People in 40 states infected with salmonella from contact with live poultry The U.S. Centers for Disease Control (CDC) is working with state public health, veterinary, and agriculture officials, and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) to investigate four multistate outbreaks of human Salmonella infections linked to contact with live poultry.
Working out in artificial gravity Engineers have built a compact human centrifuge with an exercise component: a cycle ergometer that a person can pedal as the centrifuge spins. The centrifuge was sized to just fit inside a module of the ISS. After testing the setup on healthy participants, the team found the combination of exercise and artificial gravity could significantly lessen the effects of extended weightlessness in space -- more so than exercise alone.
Make no bones about it: Female athlete triad can lead to problems with bone health Participation in sports by women and girls has increased from 310,000 individuals in 1971 to 3.37 million in 2010. At the same time, sports-related injuries among female athletes have skyrocketed. According to a new study, women with symptoms known as the 'female athlete triad' are at greater risk of bone stress injuries and fractures.
Novel DNA repair mechanism brings new horizons The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. A group of researchers has discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases.
Supercharging stem cells to create new therapies A new method for culturing stem cells has been developed, which sees the highly therapeutic cells grow faster and stronger. Stem cell therapy is showing promising signs for transplant patients, and the IL-17 treated stem cells should be even more effective at preventing and treating inflammation in transplant recipients -- particularly controlling rejection in transplant patients.
