    Low back pain with sciatica due to lumbar-disc stress-deformation and herniation is a major health problem. The myriad of data on precautions, safeguards, and management of the back have failed to reduce back-pain incidence. In addition, surgical treatment often fails to eliminate pain and complications. This article attempts to address both the preventative and treatment aspects of back pain. For... View full abstract»

    A medical devices directive is due to come into force in Europe in June 1998. Manufacturers and suppliers of wheelchairs will have to comply with this directive to make their products available on the European market. European standards for wheelchairs are being written to help people demonstrate compliance with the directive. This article summarizes the content of these standards and how they are...

    Augmented reality (AR) is a technology in which a computer-generated image is superimposed onto the user's vision of the real world, giving the user additional information generated from the computer model. This technology is different from virtual reality, in which the user is immersed in a virtual world generated by the computer. Rather, the AR system brings the computer into the "world" of the ...

    With the development of improved MR imaging techniques, there has been a resurgence of interest since the early 1980s. Today, MR flow imaging techniques are regarded as important clinical tools for providing detailed in vivo blood flow information. MR phase velocity mapping is a versatile noninvasive flow quantification method that is well suited for analyzing in vivo flow patterns. Since the intr... View full abstract»

    The introduction of photochemistry for diagnosis and therapy of several cancers has been a major contribution of modern medicine in recent years. The rationale behind this technique is old and simple: administration of a photosensitizer with high affinity to cancer cells and reactive to irradiation of appropriated wavelengths to produce singlet oxygen ( 1O 2), which causes pe...

  • How did Georg Simon Ohm do it? [Ohm's law]

    Publication Year: 1998, Page(s):107 - 109
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (659 KB)

    The "it" in the title refers to what is now known as Ohm's law. Georg Simon Ohm (1789-1854) lived at a time when there were no calibrated indicators for electric current. There was no volt or amp; these were established much later by the 1881 International Electrical Congress. The resources available to Ohm were: 1) the discovery of Oersted, who in 1520 showed that a magnetic field surrounded a wi... View full abstract»

    Several interesting aspects of the end-systolic pressure-volume relation (ESPVR) are discussed in this study, including: a) A possibility to introduce, in an explicit manner, the active force of the myocardium in the formalism describing the PVR of the left ventricle. b) A possibility to express the ventriculo-arterial coupling by using the ratio Emax/eam, in a way to disting...

  • Estimating regularity in epileptic seizure time-series data

    The authors apply Ziv-Lempel (LZ) complexity and approximate entropy (ApEn) as measures to quantify the regularity in the various epochs of epileptic seizure time series data. They demonstrate the potential of complexity measures such as LZ and ApEn in quantifying the regularity at different epochs of epileptic seizure time-series data. It is clearly shown that these measures have high values at t... View full abstract»

    What happens when an inventor who made a very small contribution to an invention is left off a patent? Can a company charged with infringement obtain a license from the omitted inventor and so scot free? That was the question before the court in the recent case of Ethicon v. U.S. Surgical. The answer the court gave was yes. The case involved surgical instruments, known as trocars, used to perform ... View full abstract»

  • Noninvasively measuring blood glucose using saliva

    Self-measurement of blood glucose level is a very important aspect in monitoring the health quality of diabetic patients who require insulin therapy. Typically, a blood sample for analysis is obtained via a finger stick or other such invasive procedure. Often, this blood collecting causes physical and mental stress to the patient. For this reason, it is desirable to establish a noninvasive bloodle... View full abstract»

    During a conventional colonoscopy examination, the endoscopist watches a video monitor that displays the real-time images being captured by a CCD camera at the distal end of the colonoscope. Some researchers believe that a computer can be used to interpret these images and be trained to recognize and correctly locate the position of the lumen. This information will then be processed and used to co... View full abstract»

    The marriage of biomedical instrumentation and patient care has once again proven itself successful. The electrothermally-assisted capsular shift is a new procedure with various potential applications. Despite its embryonic stage, this procedure is being used by a handful of shoulder surgeons who are cautiously pursuing new and improved ways to prevent the common and debilitating diagnosis of shou...

    The rapid development of minor-access surgery has greatly stimulated the design of new instruments to be more sophisticated and specialized. However, even the most sophisticated instruments available today still have significant drawbacks. As far as grasping forceps are concerned, one of the problems is the conventional mechanical articular joint with its nonlinear motion. With these articular joi... View full abstract»
