Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber dressings, described in separate papers, use naturally-occurring proteins in plants and animals to promote healing and regrow tissue.
CHICAGO--Consumption of low-calorie sweeteners could promote metabolic syndrome and predispose people to prediabetes and diabetes, particularly in individuals with obesity, a new study on human fat-derived stem cells and fat samples suggests. The research results will be presented Sunday, March 18, at ENDO 2018, the 100th annual meeting of the Endocrine Society in Chicago, Ill.
LOS ANGELES (March 18, 2018)--Interactive virtual reality (VR) brings medical images to life on screen, showing interventional radiologists a patient's unique internal anatomy to help physicians effectively prepare and tailor their approach to complex treatments, such as splenic artery aneurysm repair, according to new research being presented today at the Society of Interventional Radiology's 2018 Annual Scientific Meeting.
CHICAGO--Not enough women of childbearing age who have diabetes are receiving the recommended preconception counseling, a new study suggests. The findings will be presented in a poster on Saturday at ENDO 2018, the 100th annual meeting of the Endocrine Society in Chicago, Ill.
Women with type 1 or type 2 diabetes and their babies benefit from strict blood sugar control before and during pregnancy, and the American Diabetes Association recommends that all women who have diabetes and are of childbearing age receive preconception counseling beginning at puberty.
Chicago, IL--New scientific evidence has strengthened the case for reserving testosterone therapy for well-documented cases of hypogonadism, a condition where the body does not produce enough testosterone, Endocrine Society experts concluded in an updated Clinical Practice Guideline released today.
CHICAGO--A new study lends further evidence to a suspected link between abnormal breast growth in young boys--called prepubertal gynecomastia--and regular exposure to lavender or tea tree oil, by finding that key chemicals in these common plant-derived oils act as endocrine-disrupting chemicals. The study results will be presented Monday at ENDO 2018, the Endocrine Society's 100th annual meeting in Chicago.
An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron magnet (CoFeB) sandwiched at the ends by gold (Au) electrodes on a silicon (Si) surface. The gray arrows depict the overall direction of electric current injected into the structure at the back of the gold (Au) contact and coming out the front gold contact pad.
Researchers investigated the diet of people buried in the Ii Hamina cemetery from the 15th to the 17th centuries by analysing isotopes in the bones of the deceased. Isotopes preserve information on the various nutrient sources used by humans during their lifetime. A study published in the Environmental Archaeology journal reveals that the dominant protein source was small fish, such as roach or Baltic herring.
Occupational health researchers at Colorado State University are drawing attention to worker safety and satisfaction in a young industry still finding its feet: legal cannabis.
CSU researchers in the Department of Psychology have completed a first-of-its-kind, peer-reviewed study that examines the demographics, physical environment and psychosocial aspects of working in the cannabis trade, which is now legal in some form in over half the United States, including Colorado. The study results were published in the American Journal of Industrial Medicine.
A research team from Tokyo Institute of Technology (Tokyo Tech) and Waseda University have successfully produced high-quality thin film monocrystalline silicon with a reduced crystal defect density down to the silicon wafer level at a growth rate that is more than 10 times higher than before. In principle, this method can improve the raw material yield to nearly 100%.
Tiny jumping fish can leap further as they get older, new research shows.
Mangrove rivulus are capable of "tail-flip jumping" many times their body length when out of water, allowing them to escape predators and find better habitats.
Researchers from the universities of Exeter and Alabama looked at how physical traits and age affected how far the fish - found in the US, the Bahamas and Central America - could jump.
St. Augustine, Fla. (March 15, 2018)- Irish culture will soon be celebrated across the globe with parades, pub crawls and seas of green. But newly uncovered documents prove unlike previous belief, St. Patrick's Day celebrations did not start in Boston, rather at least 100 years earlier in St. Augustine, Florida.
In application, strength and stability of single microgels are important for controlling functions. However, their mechanical properties have been little known due to measurement difficulty. Miho Yanagisawa and Atsushi Sakai at Tokyo University of Agriculture and Technology and their colleagues succeeded in measuring the elasticity of single microgels by pulling the with a microcapillary and quantifying deformation and pressure during aspiration.
Like an island nation, the nucleus of a cell has a transportation problem. Evolution has enclosed it with a double membrane, the nuclear envelope, which protects DNA but also cuts it off from the rest of the cell. Nature's solution is a massive--by molecular standards--cylindrical configuration known as the nuclear pore complex, through which imports and exports travel, connecting the bulk of the cell with its headquarters.
In the event of a cardiorespiratory arrest, two actions are crucial for the patient's survival: cardiopulmonary resuscitation (CPR) and defibrillation. CPR consists of rhythmically compressing the patient's chest to generate a minimum flow of blood in order to minimise the deterioration of vital organs (heart and brain). And defibrillation involves applying an electric shock to try to reverse the arrhythmia.
