Some patients may no longer need hypertensive medications after bariatric surgery
Severely obese patients may experience significant, long-term improvements in blood pressure as they lose substantial amounts of weight after gastric bypass surgery, thereby contributing to their overall health, according to a new University of Pittsburgh study, published in the March issue of the Archives of Surgery. Excess body weight is associated with a host of health complications including diabetes, certain cancers and joint stress, with nearly two-thirds of very obese patients suffering from high blood pressure – the primary risk factor for both stroke and heart disease.
John Fernstrom, Ph.D., professor of psychiatry, pharmacology and neuroscience at the University of Pittsburgh School of Medicine and research director of the University of Pittsburgh Medical Center (UPMC) Weight Management Center, and colleagues analyzed data from 347 patients at the upper extreme of body weight, with a beginning Body Mass Index (BMI) of greater than 40 who underwent gastric bypass surgery at UPMC between 1992 and 2001.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
