Today researchers pay more and more attention to the content of trace elements and heavy metals in food. Contents of trace elements and heavy metals in Chinese winter jujube fruit were analyzed by ICP-MS, the results showed that winter Chinese jujube contained plentiful trace elements, especially Ca (126.67 microg x g(-1) x FW), Mg (68.04 microg x g(-1) x FW), Sr (1691.39 ng x g(-1) x FW), Zn (787.26 ng x g(-1) x FW), Fe (512.84 ng x g(-1) x FW), Mn (495.42 ng x g(-1) x FW) and Mo (33.38 ng x g(-1) x FW), which is necessary for human health and can prolong the human life. But Chinese winter jujube contains little heavy metals and accords with relative national standard.

Colorectal cancer (CRC) is one of the most prevalent and deadly malignancies worldwide. Recently, ferroptosis, a novel form of regulated cell death characterized by iron dependency and lipid peroxidation, has garnered significant attention from researchers. The mechanisms underlying ferroptosis, including intracellular iron levels, lipid peroxidation, and antioxidant system regulation, offer new insights into cancer treatment strategies.

Background: Night sweats are a condition in which an individual sweats excessively during sleep without awareness, and stops when they wake up. Prolonged episodes of night sweats might result in the depletion of trace elements and nutrients, affecting the growth and development of children.
Purpose: To investigate the relationship between sweat nights and season.

Cnidarians (sea anemones, corals, hydroids, and jellyfish) are a key outgroup for comparisons with bilaterial animals to trace the evolution of genomic complexity and diversity within the animal kingdom, as they separated from most other animals 100s of millions of years ago. Cnidarians have extensive diversity, yet the paucity of genomic resources limits our ability to compare genomic variation between cnidarian clades and species. Here we report the genome for Edwardsia elegans, a sea anemone in the most specious genus of the family Edwardsiidae, a phylogenetically important family of sea anemones that contains the model anemone Nematostella vectensis.

Here, a high molecular weight polysaccharide preparation from Ophiocordyceps gracilis was utilized as a stabilizer and dispersant to create nanocomposites based on selenium nanoparticles (GSP-1a-SeNPs). The NPs showed the highest stability at a selenium/polysaccharide mass ratio of 1:1, with no significant change after 28 days of storage at 4 °C. The NPs exhibited a symmetrical spheroid structure with an average diameter of 85.
