https://medicalxpress.com/ en-us Medical Xpress internet news portal provides the latest news on Health and Medicine. Researchers have demonstrated a new class of low-cost, scalable sensors that can be used to monitor electrical activity in human cerebral organoids. Because electrical signals are key to understanding brain function, this advancement facilitates research into both neurodevelopment and genetic disorders such as Angelman syndrome. https://medicalxpress.com/news/2026-04-scalable-sensors-genetic-disorders.html Thu, 02 Apr 2026 11:00:04 EDT news694342087 Recurrent wheezing is a serious morbidity, and it is estimated that about one-third of school-age children exhibit this symptom in the first five years of life. Recurrent wheezing in childhood is a significant risk factor for irreversible lung damage in adulthood. https://medicalxpress.com/news/2024-09-wearable-biomonitoring-sensor-stable-respiration.html Fri, 20 Sep 2024 13:30:03 EDT news646057801 Scientists at The Hospital for Sick Children (SickKids) and the University of Toronto (U of T) have combined forces to develop a new approach to potentially treat tumor cells, called mechanical nanosurgery, even for aggressive, chemoresistant cancers. https://medicalxpress.com/news/2023-04-precision-magnetics-game-changer-therapy-resistant-brain.html Tue, 11 Apr 2023 09:50:34 EDT news600425431 Urine can reveal a lot about a person's health. But physicians don't currently have a convenient or fast way of tracking the concentration of important compounds in their patients' urine. Now, researchers reporting in ACS Applied Nano Materials have designed a flexible sensor that fits in a diaper, measures multiple components in urine and can share those results over Bluetooth to provide real-time bedside analyses for incontinent, elderly or infant patients. https://medicalxpress.com/news/2022-05-smart-diaper-bedside-urine.html Thu, 05 May 2022 12:39:26 EDT news570973164 If heart attacks blared a warning signal, patients would have a better chance of avoiding them. That's the idea behind a new imaging technique developed by a Spartan-led team of researchers. https://medicalxpress.com/news/2021-08-heart.html Mon, 09 Aug 2021 11:24:20 EDT news547727042 University of Arkansas researchers Marco Fielder and Arun Nair have conducted the first study of the combined nanoscale effects of water and mineral content on the deformation mechanisms and thermal properties of collagen, the essence of bone material. https://medicalxpress.com/news/2020-12-nanoscale-effect-mineral-content-bone.html Fri, 04 Dec 2020 10:17:27 EST news526299445 Thin, flexible fibers made of carbon nanotubes have now proven able to bridge damaged heart tissues and deliver the electrical signals needed to keep those hearts beating. https://medicalxpress.com/news/2019-08-hearts-rewired-nanotube-fibers.html Tue, 13 Aug 2019 11:14:41 EDT news484913665 NUS pharmaceutical scientists, together with clinicians from the National University Health System (NUHS), have developed a nanomaterial-based hydrogel that encourages amniotic epithelial cells (a type of stem cell) to grow into mature liver cells. https://medicalxpress.com/news/2018-09-reconstructing-healthy-liver-cells-nanomaterial-based.html Mon, 24 Sep 2018 08:25:46 EDT news456996340 Ingested or injected pharmaceuticals can target specific molecules involved in disease processes, but get distributed throughout the body where they can cause unwanted side effects. An approach known as electroceuticals aims to avoid systemic exposure by using small wires to electrically monitor and manipulate individual nerves that control organ function and carry information about disease. Despite the promise of electroceuticals, it has been challenging to develop long-term therapies due to the lack of biocompatible wires. Now, NIBIB-funded researches have spun carbon nanotubes into flexible, nerve-sized wires or yarns capable of high-fidelity long-term connections in live animals. The development of these biocompatible yarns opens the possibility of new bioelectric diagnostics and therapies through regulation of internal organ function at the single nerve level. https://medicalxpress.com/news/2018-02-carbon-yarn-nerves-electroceutical-treatments.html Tue, 27 Feb 2018 08:34:39 EST news438942865 (Medical Xpress) -- Of the world’s leading causes of death, stroke ranks second – and occurring 8 out of 10 times is ischemic stroke: reduced blood supply to the brain creates a shortage of oxygen, glucose and other nutrients and an increase in metabolic waste, leading to neuronal damage that results in physiological impairment or death. At the molecular level, the genetic activation of the nucleic acid protein Caspase-3 – a member of the cysteine-aspartic acid protease (caspase) family – is a major factor in loss of neuronal tissue and associated apoptosis (programmed cell death). Post-stroke treatments known to be effective at reducing or reversing damage involve preventing Caspase-3 activation, either by genetic or pharmacological intervention. Recently, however, a group of European researchers combined these modalities by using functionalized carbon nanotubes (f-CNT) – nanotubes made soluble by attaching certain molecules to their sidewalls – to deliver siRNA (silencing RNA) to ischemically-impacted neuronal tissue in vivo. https://medicalxpress.com/news/2011-07-softly-tiny-recovery-nanotube-delivered-sirna.html Tue, 05 Jul 2011 09:30:01 EDT news229021756
