Paramagnetic Seeds: An Effective Option for Breast Lesion Localization
Paramagnetic seeds along with superparamagnetic iron oxide (SPIO) was an effective combination for nonpalpable breast lesion localization and sentinel lymph node detection (SLND), data from the MAGTOTAL trial in Sweden showed. The totally magnetic technique was equivalent to the use of guidewire and SPIO regarding re-excision frequency at 2.84% versus 2.87%, for a difference of […]
How plants protect themselves from oxidative stress during iron uptake — and why this is also important for humans: Biology, chemistry and medicine: Interdisciplinary publication in Plant Physiology
Iron is a critical micronutrient for the survival of plants and humans, yet too much iron can also be toxic. An interdisciplinary research team from Heinrich Heine University Düsseldorf (HHU) has discovered that the protein PATELLIN2 is not only involved in regulating iron levels in plants. PATELLIN2 is one of a group of proteins that […]
How did Earth avoid a Mars-like fate? Ancient rocks hold clues: New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field
Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth’s outer core generates our planet’s protective magnetic field. This magnetic field is invisible but is vital for life on Earth’s surface because it shields the planet from solar wind — streams of radiation from the sun. About 565 million years ago, however, the […]
Moderate drinking linked to brain changes and cognitive decline
Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people publishing July 14 in the open access journal PLOS Medicine. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a potential mechanism […]
Rusting iron can be its own worst enemy: Simulations show iron catalyzes corrosion in ‘inert’ carbon dioxide
Iron that rusts in water theoretically shouldn’t corrode in contact with an “inert” supercritical fluid of carbon dioxide. But it does. The reason has eluded materials scientists to now, but a team at Rice University has a theory that could contribute to new strategies to protect iron from the environment. Materials theorist Boris Yakobson and […]
Researchers recreate deep-Earth conditions to see how iron copes with extreme stress: New observations of the atomic structure of iron reveal it undergoes
Far below you lies a sphere of solid iron and nickel about as wide as the broadest part of Texas: the Earth’s inner core. The metal at the inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun’s surface. Earth’s […]
One in two pregnancies are affected by iron deficiency, yet many women don’t get a simple screening test to check
Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a paper published today in the journal Blood Advances. But despite how common iron deficiency is, 40% of pregnant women in this large regional study never […]
Heart, Death Risks Linked With CKD-Related Iron Deficiency
Regardless of anemia, iron deficiency in patients with late-stage chronic kidney disease (CKD) was linked with adverse health outcomes, an observational study found. In 5,145 patients with stage 3-5 CKD not on dialysis, a transferrin saturation (TSAT) of 15% or less was associated with a higher risk for all-cause mortality before reaching dialysis or kidney […]
