Expansive arterial remodeling (EAR) comprises a genetically programmed biological response designed to restore homeostatic levels of arterial wall stress after an increase in vessel flow load occurs. The magnitude and rate of EAR reactions relative to local hemodynamic stress fields and the tensile strength of vascular tissue determines whether the process will result in a stable mural structure (adaptive remodeling) or an unstable mural structure that progresses to form an aneurysm (maladaptive remodeling).
First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod.
Rice materials scientist Rouzbeh Shahsavari and his team used molecular models to demonstrate their theory that weak van der Waals forces between the inner surface of the nanotube and the water molecules are strong enough to snap the oxygen and hydrogen atoms into place.
Disruptive noise is almost everywhere, from people talking in the office corridor to road construction down the street to the neighbor's lawn mower. Research being conducted at the University of Illinois' Coordinated Science Laboratory is looking to improve this noisy frustration.
New model explains interactions between small copper clusters used as low-cost catalysts in the production of hydrogen by breaking down water molecules
Leishmania is a microorganism that enters the human body via a sandfly bite. Instead of fleeing the white blood cells deployed by the immune system to destroy it, the parasite allows itself to be swallowed up. In doing so, Leishmania has developed the ideal strategy for continuing its life cycle, threatening the health of over 500 million people at risk of crossing its path in Africa, Europe, Asia, and the Americas.
Globally, one in three people drink alcohol (equivalent to 2.4 billion people), and 2.2% of women and 6.8% of men die from alcohol-related health problems each year.
Alcohol use was ranked as the seventh leading risk factor for premature death and disability worldwide in 2016, and was the leading cause for people aged 15-49 years old. In this age group, it is associated with tuberculosis, road injuries, and self-harm.
Humans instinctively adopt the gait that requires the least amount of energy given the walking conditions. Without realizing it, we are constantly tweaking our pace, stride length and foot lift. But could we consciously play with these parameters in order to influence our energy expenditure?
For decades researchers have worked to shed light on the causes of neurodegenerative disorders, a group of devastating conditions, including Alzheimer's and Parkinson's, that involve the progressive loss of neurons and nervous system function. In recent years, numerous factors, from genetic mutations to viral infections, have been found to contribute to the development of these diseases.
Bottom Line: Compared with non-drinkers, men who consumed at least seven drinks per week during adolescence (ages 15-19) had three times the odds of being diagnosed with clinically significant prostate cancer.

CINCINNATI - Scientists may be on the road to solving the mystery of a group of mostly incurable blood diseases called myelodysplastic syndromes (MDS), which cause people to have immature, malfunctioning bone marrow cells that fuel a diverse set of health problems and can lead to leukemia.
