The effect of S nutrition level (standard-2 and intensive-6 or 9 mmol S L) on the growth, micronutrient status, and Cd concentration of Cd-exposed (0, 0.0002, 0.02, and 0.04 mmol Cd L) L. 'Zebra' was examined. The hypothesis that Cd-induced micronutrient imbalance in this species is alleviated by enhanced S-sulfate (S-SO) nutrition was tested. The intensive S nutrition, especially the dose of 6 mmol L, to some extent alleviated Cd-induced stress by improving the adverse changes in micronutrient status and increase of the biomass. The root and shoot Fe, Cu, Mn, and Zn concentrations of Cd-exposed wheat rose at 6 and remained unaltered at 9 mmol S L. Particularly noteworthy is the substantial increase of Fe bioconcentration found in Cd-stressed plants at 6 mmol S L. The root Cu concentration increased at 6 and decreased at 9 mmol S L, but did not change in shoots. Simultaneously, both the high S levels elevated the shoot Cl concentration but had no effect on the root Cl concentration. There were no substantial changes in the Mo concentration. The intensive S nutrition of the Cd-treated wheat did not affect the translocation factor (TF) of Fe and B. In turn, root-to-shoot translocation of Mo and Zn was enhanced at 6 and remained unchanged at 9 mmol S L. The changes in TF of Cl, Cu, and Mn varied greatly, depending on the S and Cd concentrations. Intensive S nutrition of Cd-stressed wheat, as a rule, dropped the root and increased the shoot Cd concentration as well as reduced Cd bioconcentration/bioaccumulation factor enhancing root-to-shoot Cd translocation.

The offshore oilfields in the North Sea area are increasingly employed for projects beyond oil production, like carbon capture and storage (CCS). Still, the fossil fuel production from mature fields is significant. It has raised environmental concerns associated with discharging produced waters (PW) and drilling mud into the sea.

Background: Inflammation and inadequate nutrition are common in older age and known to affect iron homeostasis. However, it is not known whether a pro-inflammatory diet affects iron status in older adults. We investigated the diet quality of healthy older adults considering markers of iron homeostasis and inflammation compared to a younger control.

Background & Aims: Malnutrition is highly prevalent in those with cancer and more so in those with incurable cancer. In incurable cancer, it is widely agreed that optimal nutritional care has the potential to positively impact patient and caregiver distress and oncological outcomes. The aim of this systematic review was to describe the diversity and frequency of nutritional interventions, whether given in isolation or as part of a multimodal intervention in those with incurable cancer, in randomised controlled trials.

Background And Purpose: Bioavailability studies and observational evidence suggest that heme iron (HI) may have greater impact on iron status indicators compared with non-heme iron (NHI). This systematic review and meta-analysis aimed to review the current evidence on the effect of the administration of HI compared with NHI for improving iron status in non-hospitalized population groups.
Methods: We searched Pubmed, CENTRAL, Scopus, Web of Science, and LILACS from inception to July 2024.

BackgroundAt present, there is a lack of efficient biomarkers for the diagnosis of thyroid cancer, and the influence of natural factors such as high iodine exposure on the expression of biomarkers remains unclear.MethodsSerum samples from papillary thyroid cancer (PTC) and non-cancer controls matched 1:1 in different iodine nutritional regions were analyzed metabolomically using an ultra-high performance liquid chromatography-Orbitrap Exploris mass spectrometry (UHPLC-OE-MS) platform. Then the data were randomly divided into training and test sets in a 1:1 ratio according to the different iodine nutritional regions and different PTC status.
