Food is essential for human survival; however, food can be an important route of exposure to contaminants. This study investigated the presence and distribution of anthropogenic contaminants in food consumed by families with small children in South Florida, United States, evaluating seasonal and socio-economic variabilities in chemical composition. QuEChERS protocols, followed by non-targeted analysis (NTA) using an LC-Orbitrap HRMS system, were used for the comprehensive screening of organic contaminants.

Soil samples from ten agricultural towns were analyzed for radionuclide concentrations using gamma-ray spectrometry. Primordial radionuclides such as 238U, 232Th, and 40K were examined, with 40K showing the highest concentration due to the potassium-rich nature of phosphate fertilizers.

Until now, thymic anatomy has been studied using histological thin sections or confocal microscopy 3D reconstruction, necessarily for limited volumes.
Methods: We used Phase Contrast X-Ray Computed Tomography to address the lack of whole-organ volumetric information on the microarchitecture of its structural components.
Article Synopsis
- PFAS, or per-and polyfluoroalkyl substances, are synthetic chemicals used in various industries and are known for their persistence and toxicity in marine life, prompting research into their effects on fish and water quality.
- The study found detectable PFAS levels in recreational fisheries, with a notable difference in bioaccumulation between species, particularly indicating higher accumulation in tuna than in lobster.
- Despite healthy fish conditions indicated by Fulton's condition factor, biomarkers showed oxidative stress in both tuna and lobster, suggesting potential risks to their health and raising concerns about the accuracy of human health risk assessments related to PFAS exposure.
Article Synopsis
- Men of African descent experience the highest rates of prostate cancer, but the genetic factors behind this have not been thoroughly explored.
- Researchers analyzed genetic data from nearly 4,000 prostate cancer cases and over 3,500 controls across several African countries to identify specific genetic associations related to the disease.
- The study found 15 significant genetic associations, including four new ones, highlighting that genetic variation in prostate cancer is influenced by unique African alleles, suggesting that more research in diverse populations is crucial for understanding cancer genetics.
