Researchers at Osaka University discovered that mutant variants of the RyR1 calcium channel protein are more sensitive to heat than normal proteins, leading to a cycle of activation that can cause malignant hyperthermia. This finding provides new insight into the condition and could lead to preventive and treatment strategies.
A multidisciplinary research group uses magnetotactic bacteria to create nanomagnetic structures, which can be steered through the human body via external magnetic fields. They have developed a new method to measure the magnetic properties of individual nanomagnets in biological entities, enabling precise control over these structures.
Researchers have developed a new, high-power short-duration (HPSD) protocol for treating cardiac arrhythmias using radiofrequency energy and catheterization. The study shows this protocol is more effective than conventional ones in achieving shallower but extensive lesions, minimizing clinical complications.
Researchers have developed a magnesium alloy that can be used to treat tumors using a low-intensity magnetic field. The alloy, known as MgA, can rapidly heat up under the influence of an alternating magnetic field (AMF), resulting in effective tumor ablation.
Researchers recommend keeping a small dose of dantrolene on hand and having a fully stocked cart elsewhere, as the incidence of the reaction is low. Maintaining a fully stocked cart would divert funds from other patient safety initiatives.
A meta-analysis found rebound hyperthermia to be associated with significantly worse neurologic outcomes and mortality in survivors of cardiac arrest. The study emphasizes the potential detrimental effects of fever on neurological recovery during rewarming phase.
Researchers have found a link between malignant hyperthermia susceptibility and exertional heat stroke in mice. The study suggests that intense exercise in challenging environmental conditions can trigger lethal crises in susceptible animals, which may be relevant to humans.
A novel hyperthermia method has been developed for preventing and treating Schistosomiasis japonica by targeting migrating skin schistosomula. The treatment shows promising results in reducing the survival rate of cercariae and worm reduction rates, offering a potential alternative to PZQ.
Researchers have discovered a magnetic material that can heat cancer cells to high temperatures without harming healthy tissue. This breakthrough material uses a unique Curie temperature-dependent heating effect that stops quickly and cannot get hotter.
Dartmouth College researchers create a new class of flower-shaped magnetic nanoparticles that heat at low field strengths, showing improved performance compared to commercially available counterparts. This breakthrough could enable treatment of deep-seated tumors like pancreatic cancer.
The study found that inhibiting neurons in specific brain regions eliminated stress-induced heat production and increased body temperature in rats. Stimulating these neurons caused the opposite effect, highlighting a key neural circuit connection in the development of psychological stress-induced hyperthermia.
Researchers found that hyperthermia treatment completely destroyed the blood-brain barrier surrounding tumors, allowing chemotherapy drugs to target and kill cancer cells. Additionally, hyperthermia combined with radiotherapy showed synergistic benefits in treating brain gliomas.
Researchers have developed a new method to target and destroy cancerous cells using hyperthermia, which elevates the temperature of tumor cells while keeping surrounding healthy tissue at a lower degree of body heat. The technique uses ferrofluids to induce hyperthermia and has been shown to be biocompatible with iron oxide nanoparticles.
Researchers found that combining regional hyperthermia with chemotherapy increases local progression-free and disease-free survival rates in high-risk sarcoma patients. The treatment has shown promise, but the safety profile remains a concern.
A genetic disorder linked to fatal muscle contractions during anesthesia may also be connected to heat stroke, according to new research. The study found that antioxidants could protect against heat stroke in genetically prone individuals.
A phase III study of 341 high-risk patients with deep, local sarcomas shows significant improvement in tumour response and survival rates when treated with a combination of chemotherapy and local, deep hyperthermia. The combined therapy has been applied to patients before surgery, demonstrating its effectiveness.
Researchers propose a new test for diagnosing malignant hyperthermia by measuring carbon dioxide pressure after caffeine injection, showing increased CO2 levels in susceptible individuals. Further testing is needed to define sensitivity and specificity of the test before it can be used for diagnosis.
