Stem cells used to learn how common mutation in Asians affects heart health

Stem cells used to learn how common mutation in Asians affects heart health

Over 500 million people worldwide carry a genetic mutation that disables a common metabolic protein called ALDH2. The mutation, which predominantly occurs in people of East Asian descent, leads to an increased risk of heart disease and poorer outcomes after a heart attack. It also causes facial flushing when carriers drink alcohol. Continue reading

Skin cells can be engineered into pulmonary valves for pediatric patients

Skin cells can be engineered into pulmonary valves for pediatric patients

Researchers have found a way to take a pediatric patient’s skin cells, reprogram the skin cells to function as heart valvular cells, and then use the cells as part of a tissue-engineered pulmonary valve. A proof of concept study published in the September 2014 issue of The Annals of Thoracic Surgery provides more detail on this scientific development. “Current valve replacements cannot grow with patients as they age, but the use of a patient-specific pulmonary valve would introduce a ‘living’ valvular construct that should grow with the patient.

Shrink-wrapping spacesuits: Spacesuits of the future may resemble a streamlined second skin

Shrink-wrapping spacesuits: Spacesuits of the future may resemble a streamlined second skin

For future astronauts, the process of suiting up may go something like this: Instead of climbing into a conventional, bulky, gas-pressurized suit, an astronaut may don a lightweight, stretchy garment, lined with tiny, musclelike coils. She would then plug in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around her body. Continue reading

Sharks’ skin has teeth in the fight against hospital superbugs

Sharks’ skin has teeth in the fight against hospital superbugs

Transmission of bacterial infections, including MRSA and MSSA could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin, according to research published in the open access journal Antimicrobial Resistance and Infection Control . The study modelled how well different materials prevented the spread of human disease bacteria through touching, sneezes or spillages. Continue reading

Potential risk factors for urinary tract infections in young girls

Potential risk factors for urinary tract infections in young girls

Young girls with an intense, red, itchy rash on their outer genital organs may be at increased risk of developing urinary tract infections (UTIs), according to new research from Wake Forest Baptist Medical Center. The treatment may be as simple as better hygiene and avoiding potential irritants such as bubble baths and swimming pools Continue reading

Scientists learn more about rare skin cancer that killed Bob Marley

Scientists learn more about rare skin cancer that killed Bob Marley

Acral melanomas, the rare type of skin cancer that caused musician Bob Marley’s death, are genetically distinct from other types of skin cancer. Cancer Research UK scientists have discovered that acral melanomas — the rare type of skin cancer that caused reggae musician Bob Marley’s death — are genetically distinct from other more common types of skin cancer, according to a study published in the journal Pigment Cell & Melanoma Research Continue reading
