Controlled delivery of peptide nanofibers for myocardial protection

Reminiscent of the 1966 sci-fi thriller Fantastic Voyage, where a surgical team is miniaturized and injected into a dying man, researchers from Harvard Medical School have used injectable self-assembling peptide nanofibers loaded with the pro-survival factor PDGF-BB to protect rat cardiomyocytes from injury and subsequent heart failure.

Getting old? Slowing down? Blame inefficient mitochondria

In mitochondria, the fuel is oxidised and builds up a pressure of hydrogen ions (protons). These force through molecular turbines and enable the cell to generate ATP, an energy unit that can be used throughout the cell.

Children with heart defects benefit from exercise

A small but compelling pilot study indicates that many children with serious congenital heart disease, who are typically urged to restrict their activity, can improve their cardiovascular function and exercise capacity through a cardiac rehabilitation program.

Study of 30-day extended wear contact lenses

A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive 24-hour periods.
