Objective: To analyse the trace elements presented in the same germplasm of Flos Lonicerae with the soil in different producing areas of crude drugs and to investigate, the relationship between the trace elements and the characteristics of the geo-authentic Flos Lonicerae in the soil and crude drugs.
Method: The analyses on the trace elements of soil and crude drugs were made by ICP-AES.
Result: The contents of Sr, K, Na, Mg and Ca were higher in the geo-authentic areas, and the contents of Ca, Sr and Fe were higher, but the Cr and Pb were lower in the geo-authentic Flos Lonicerae. The geo-authentic crude drugs had a strong tendency to accumulate P and Cu.
Conclusion: There are no direct relationship between the concentrations of trace elements in Flos Lonicerae and those in their corresponding soil. There are good relationship between the absorption and accumulation of Ca and Cr, Co, Na and Fe; Zn and Co, Cr, Mn; Na and Co; Mg and Mn.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.

Background: The long-term follow-up studies investigating the risk of anemia and iron deficiency following bariatric procedures are scarce. This study aimed to determine the influence of body weight reduction and type of bariatric surgery on iron metabolism parameters.
Methods: We included 138 consecutive patients who underwent bariatric surgery (120 underwent sleeve gastrectomy and 18 underwent other types of bariatric surgery) between 2010 and 2016.
The Inhibitory Effects of NCT503 and Exogenous Serine on High-Selenium Induced Insulin Resistance in Mice.

National Institute for Nutrition and Health, Chinese Center for Disease Control and Prevention, Beijing 100050, China.
Objective: This study aims to identify whether the development of insulin resistance (IR) induced by high selenium (Se) is related to serine deficiency via the inhibition of the de novo serine synthesis pathway (SSP) by the administrations of 3-phosphoglycerate dehydrogenase (PHGDH) inhibitor (NCT503) or exogenous serine in mice.
Method: forty-eight male C57BL/6J mice were randomly divided into four groups: adequate-Se (0.1 mgSe/kg), high-Se (0.

Background/objectives: While studies in rat pups suggest that early zinc exposure is critical for optimal brain structure and function, associations of prenatal zinc intake with measures of brain development in infants are unknown. This study aimed to assess the associations of maternal zinc intake during pregnancy with MRI measures of brain tissue microstructure and neurodevelopmental outcomes, as well as to determine whether MRI measures of the brain mediated the relationship between maternal zinc intake and neurodevelopmental indices.
Methods: Forty-one adolescent mothers were recruited for a longitudinal study during pregnancy.
