Regulation of iron-siderophore uptake in a diazotrophic cyanobacterium Anabaena anabaena 7120
The Indian Journal of Agricultural Sciences, 2014 The regulation of 55Fe-siderophore uptake of was studied in a diazotrophic cyanobacterium Anabaena 7120. The uptake up to 20 min was found to be biphasic, a rapid first and steady second phase.

Limnology and Oceanography, Volume 70, Issue 11, Page 3155-3171, November 2025.Abstract Aerosol dust deposited on the nutrient‐deprived surface ocean can boost phytoplankton growth and oceanic carbon uptake. Low mineral solubility restricts the biological utilization of dust‐nutrients, thereby benefiting phytoplankton that actively dissolve dust.

Iron Is Filtered by the Kidney and Is Reabsorbed by the Proximal Tubule
Frontiers in Physiology, 2021 The aim of this study was to determine the iron (Fe) concentration profile within the lumen of the S2 renal proximal convoluted tubule (PCT) and to resolve whether this nephron segment transported Fe.

LOSS OF IRON FROM MOUSE PERITONEAL MACROPHAGES IN VITRO AFTER UPTAKE OF [55FE]FERRITIN AND [55FE]FERRITIN RABBIT ANTIFERRITIN COMPLEXES [PDF]
The Journal of Cell Biology, 1974 Mouse peritoneal macrophages in culture for 24 h were exposed to horse [55Fe]ferritin and rabbit antihorse [55Fe]ferritin antibody complex and the amount of 55Fe in the medium was assayed up to 2 days after the pulse uptake. Cell survival was assayed by photographing the same areas of the tissue culture Petri dish on successive days and by counting ...

CASPER‐AI: Machine Learning Applied to Active Collimation in Monolithic Arrays of SDDs
X-Ray Spectrometry, Volume 54, Issue 6, Page 813-818, November/December 2025.ABSTRACT Monolithic arrays of Silicon Drift Detectors (SDDs) have advanced X‐ray spectroscopy by providing excellent energy resolution and high rates at near ambient temperatures. Despite these benefits, they are affected by charge sharing (CS), where photogenerated charge clouds spread across adjacent channels.

What Does Iron Mean to an Oligodendrocyte?
Glia, Volume 73, Issue 9, Page 1784-1804, September 2025.Main Points Iron is essential for oligodendrocyte (OL) biology and myelin production, with deficiencies leading to severe neurological impairments. Understanding iron trafficking in OLs is crucial for developing treatments for dysmyelinating conditions. ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions.

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.Abstract The Southern Ocean today is a globally relevant sink for atmospheric carbon dioxide (CO2 ${\text{CO}}_{2}$), where the biological uptake of carbon through primary productivity is largely controlled by widespread iron (Fe) limitation. We analyze observations from a submesoscale‐resolving cross‐section of the Antarctic Circumpolar Current (ACC ...
