Wireless implantable cardioverter-defibrillators (ICDs) eliminate the lead-related complications that come with a wired ICD, but they are unsuitable for patients with ventricular tachycardia, when the heart beats too quickly, or bradycardia, when the resting heart rate is seen as low. https://medicalxpress.com/news/2024-05-modular-communicative-leadless-icd-safe.html Sat, 18 May 2024 10:00:01 EDT news635157309 It's a well-established fact that every cell in your body responds to physical touch. They don't all react in exactly the same way—a cell in your spleen won't jump like a frightened cat if it gets poked by a needle. But throughout the human body, the physical materials and structures that envelop and support cells as they grow and go about their daily tasks play a large role in their health and behavior. https://medicalxpress.com/news/2023-02-neuroscientists-touch-sensitive-electrically-responsive-proteins.html Fri, 24 Feb 2023 10:34:23 EST news596457260 Can inexpensive technologies provide a helping hand during birth? A new study in open-access journal Frontiers in Global Women's Health has revealed a low-cost sensing glove that could do just that. The researchers created the device to assist healthcare staff in identifying fetal position and the force applied to the fetal head during labor, factors that can contribute to obstructed labor and poor birth outcomes. The technology can provide real-time data during vaginal examinations, potentially improving birth outcomes in low-resource regions. https://medicalxpress.com/news/2023-01-smart-glove-dangerous-births-fetal.html Mon, 30 Jan 2023 03:58:26 EST news594273499 Gym-goers may get frustrated when they don't see results from weightlifting right away, but their efforts are not in vain: the first few weeks of training strengthen the nervous system, not muscles. New research published in JNeurosci reveals how. https://medicalxpress.com/news/2020-06-weights-nervous-stronger.html Mon, 29 Jun 2020 13:00:01 EDT news512633718 Whether stubbing a toe or stroking a cat, the sensation of touch starts out as a mechanical force that is then transformed into an electrical signal conveying pain or other sensations. Tiny channels in neurons act as translators by helping to formulate that signal to the brain. However, scientists know little about the fine details of how these channels work. https://medicalxpress.com/news/2014-12-atomic-level-view-insight-nerve.html Wed, 03 Dec 2014 13:00:01 EST news336833474 Florida State University researchers led by physics doctoral student Campion Loong have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat. https://medicalxpress.com/news/2012-08-yields-firsts-protein-crucial-human.html Fri, 31 Aug 2012 11:50:29 EDT news265632623 Loss of bone density leads to brittle bones that fracture easily. It is a major complication of spinal cord injury (SCI), which affects about 250,000 Americans every year. https://medicalxpress.com/news/2012-02-high-doses-loss-bone-spinal.html Thu, 16 Feb 2012 13:31:06 EST news248621456 A new method for identifying bacteria that cause urinary tract infections (UTIs) will lead to much faster, more effective treatment as well as a reduction in costs. The procedure, described in the Journal of Medical Microbiology, could eventually be used for the identification of micro-organisms in other bodily fluids, including blood and spinal fluid. https://medicalxpress.com/news/2012-01-method-uti-causing-bacteria-treatment.html Wed, 25 Jan 2012 03:52:23 EST news246685915
