Electronic Handheld Blood Pressure Devices Market Reaching up to $793 Million by 2010

Electronic handheld blood pressure devices are automated blood pressure measuring devices used for measuring blood pressure at regular intervals, without causing inconvenience to the individual's daily routine. Rising healthcare expenditure and rapidly aging population are key factors contributing towards a rise in demand for such devices, particularly in the developed regions of the world. With growing environmental concerns related to the use of mercury-based traditional sphygmomanometers, developed nations have stepped up efforts to replace mercury devices with electronic blood pressure devices.

HPBB 2008 - Fith International High Pressure Biosciences & Biotechnology Conference, CA, USA

HPBB conferences bring together individuals who have much more in common than simply a need for high pressure (HP) pumps, vessels and gauges. They bring together people who think about pressure influences on biological processes in different ways in the hope of creating a synergy that is greater than the sum of its parts. The participants of this conference will include a range of science and engineering students and professionals with interests in pressure pasteurization, food processing, food chemistry, the thermodynamic influences of pressure on proteins, lipids, nucleic acids and other molecules, and those interested in HP life in deep-sea and deep-subsurface environments.

Researchers produce 3-D nanotube circuits

A team of researchers at the National Institute of Advanced Industrial Science and Technology in Tsukuba, Ibaraki Prefecture, has succeeded in producing hyperfine 3-D circuits using carbon nanotubes, it was learned Sunday. The team led by Kenji Hata released their findings in the on-line version of the May 4 issue of Nature Nanotechnology. The discovery is expected to help reduce the size of integrated circuits and allow the development of highly sophisticated sensors, the researchers said. The researchers synthesized nanotubes by blowing carbon gas that had been heated to about 800 C over a silicon board.

First Use Of DNA Fingerprinting To Identify Viable Embryos

Fertility researchers have used DNA fingerprinting for the first time to identify which embryos have implanted after in vitro fertilisation (IVF) and developed successfully to result in the births of healthy babies. The technique, combined with sampling cells from blastocysts (the very early embryo) before implantation in the womb, opens the way to pin-pointing a handful of genes that could be used to identify those blastocysts most likely to result in a successful pregnancy.

Double Duty: Loss Of Protective Heart Failure Protein Causes High Blood Pressure

Scientists at the Center for Translational Medicine at Thomas Jefferson University in Philadelphia have found that a protein that appears to have protective and perhaps healing effects for failing hearts also plays a similar role in high blood pressure. They found lower-than-normal levels of the protein S100A1 in cells that line blood vessel walls in animals with high blood pressure.

NC State Researchers Identify Genes Key to Hormone Production in Plants

Researchers at North Carolina State University have pinpointed a small group of genes responsible for "telling" plants when, where and how to produce a hormone that is key to their development. Their findings shed light on the ways in which hormone production in plants affects both a plant's growth and its ability to adapt to changing environments. Full story

Mayo Clinic Proceedings examines link between bacteria in the digestive system and obesity

ROCHESTER, Minn. -- Obesity is more than a cosmetic concern because it increases a person’s risk for developing high blood pressure, diabetes and many other serious health problems. It’s well understood that consuming more calories than you expend through exercise and daily activities causes weight gain. But with about one in every three American adults now considered obese, researchers are attempting to identify additional factors that affect a person’s tendency to gain and retain excess weight. In the April issue of Mayo Clinic Proceedings, researchers from Mayo Clinic Arizona and Arizona State University examine the role that bacteria in the human gastrointestinal tract play in regulating weight and the development of obesity.

Researchers Find Gene Determinants Of C-Reactive Protein

Researchers at Brigham and Women's Hospital (BWH) have found that variation in several genes that are associated with metabolic and inflammatory regulation – in diseases such as diabetes and heart disease – also have significant effects on C-reactive protein (CRP) levels.

Researchers Infiltrate and 'Pollute' Storm Botnet

ancientribe writes "Dark Reading reports that a group of European researchers has found a way to disrupt the massive Storm botnet by infiltrating it and injecting "polluted" content into it to disrupt communication among the bots and their controlling hosts. Other researchers have historically shied way from this controversial method because they don't "want to mess with other peoples' PCs by injecting commands," said one botnet expert quoted in the article.

Researchers fool WiFi positioning on iPhone, Touch

The iPhone's WiFi positioning system can be fooled into providing false results, a report claims from researchers at ETH Zurich. According to TG Daily, researchers were able to circumvent the Skyhook-owned service in a "fairly simple manner". The technology traditionally relies on detected MAC addresses that relay information to the central server, and by spoofing a real access point, users can generate any number of false points, as well as jam up real ones.

Researchers Play Tune Recorded Before Edison

Tree131 writes "The New York Times is reporting that sound recordings pre-dating Edison's made by Édouard-Léon Scott de Martinville, a Parisian typesetter and tinkerer, were discovered by American audio historians at the French Academy of Sciences in Paris. The archives are on paper and were meant for recording but not playback. Researchers used a high quality scan of the recording and an electronic needle to play back the sounds recorded 150 years ago. 'For more than a century, since he captured the spoken words "Mary had a little lamb" on a sheet of tinfoil, Thomas Edison has been considered the father of recorded sound. But researchers say they have unearthed a recording of the human voice, made by a little-known Frenchman, that predates Edison's invention of the phonograph by nearly two decades.
