The possibility of using conventional analysis, such as gamma spectrometry and alpha spectrometry, for the detection of traces of depleted uranium (DU) in environmental samples has been investigated. The expected values have been compared with the experimental results obtained by using mollusc samples gathered in the Adriatic Sea. The analysis has shown that it is possible to detect DU. if the percentage composition is about 20% depleted uranium and 80% natural uranium, for a sample containing 10 Bq x kg(-1) of 238U. The possibility of extending this approach to samples with any given uranium concentration is investigated.

Uranium poisoning, particularly from exposure to Depleted Uranium (DU), occurs when uranyl ions enter the bloodstream and bind primarily to transferrin, osteopontin, and albumin before entering cells via corresponding receptors on renal tubular membranes, leading to cellular damage. Uranium poisoning remains a significant clinical challenge, with no ideal treatment currently available. In this study, we investigate the therapeutic potential of human umbilical cord-derived mesenchymal stem cell exosomes (MSC-EXs) in mice exposed to DU.

- The study investigates uranium (U/U) ratios in environmental samples from the Pamir region to evaluate the influence of human nuclear activity on this remote area.
- The U/U ratios found (ranging from 0.007256 to 0.007263) suggest a slight enrichment of uranium, indicating the presence of anthropogenic materials, particularly in cryoconite compared to soil and water.
- The findings also suggest that while the area shows subtle enrichment of uranium, it remains relatively clean from local contamination, with environmental uranium largely resulting from historical global nuclear fallout rather than local sources.
Mitigation of depleted uranium-induced mitochondrial damage by ethylmalonic encephalopathy 1 protein via modulation of hydrogen sulfide and glutathione pathways.

Depleted uranium (DU) is a byproduct of uranium enrichment, which can cause heavy-metal toxicity and radiation toxicity as well as serious damage to the kidneys. However, the mechanism of renal injury induced by DU is still unclear. This study aimed to explore the role of ethylmalonic encephalopathy 1 (ETHE1) in DU-induced mitochondrial dysfunction and elucidate the underlying mechanisms.

With the depletion of fossil fuels and increasing pollution problems, green and sustainable energy supply attracts worldwide attention. Hydrogen is a green and high-density energy substance, and photocatalytic hydrogen generation is an effective and sustainable method. Therefore, developing high-performance photocatalysts plays a crucial role in practical application.

During the spring of 2024, 33 members of a group of Gulf War I veterans wounded in depleted uranium (DU) friendly-fire incidents were seen at the Baltimore VA Medical Center for surveillance related to their combat exposure. The cohort was assessed with a protocol which includes exposure monitoring for total and isotopic uranium (U) concentrations in urine and a comprehensive assessment of health outcomes including measures of bone metabolism and bone mineral density (BMD). An audiometry examination of the cohort was added to assess for acoustic trauma and toxic metal effects in this surveillance episode marking over 30 years since this exposure event.
