Co-application of titanium nanoparticles and melatonin effectively lowered chromium toxicity in lemon balm (Melissa officinalis L.) through modifying biochemical characteristics
Environ Sci Pollut Res Int. 2024 Mar 11. doi: 10.1007/s11356-024-32771-7. Online ahead of print.ABSTRACTChromium (Cr) toxicity can negatively affect plant growth and development, impacting agricultural productivity and posing risks to human health. Metallic nanoparticles (MNPs) such as titanium dioxide (TiO2) and natural growth regulators such as melatonin (MT) become a promising technology to manage heavy metal-contaminated soils and promote safe food production. The present work was conducted to find the effect of foliar application of TiO2 NPs (15 mg L-1) and MT (100 µM) on growth, biochemical attributes, and Cr accumu...

Chromium immobilization from wastewater via iron-modified hydrochar: Different iron fabricants and practicality assessment
Ecotoxicol Environ Saf. 2024 Mar 11;274:116132. doi: 10.1016/j.ecoenv.2024.116132. Online ahead of print.ABSTRACTThe recycling of industrial solid by-products such as red mud (RM) has become an urgent priority, due to their large quantities and lack of reutilization methods can lead to resource wastage. In this work, RM was employed to fabricate green hydrochar (HC) to prepare zero-valent iron (ZVI) modified carbonous materials, and conventional iron salts (IS, FeCl3) was applied as comparison, fabricated HC labeled as RM/HC and IS/HC, respectively. The physicochemical properties of these HC were comprehensively characteri...

Effects of the SEMA4B gene on hexavalent chromium [Cr(VI)]-induced malignant transformation of human bronchial epithelial cells
This study aimed to investigate the role of the SEMA4B gene in Cr(VI)-mediated malignant transformation of human bronchial epithelial (BEAS-2B) cells. In our population survey of workers, the geometric mean [95% confidence intervals (CIs)] of Cr in blood was 3.80 (0.42, 26.56) μg/L. Following treatment with various doses of Cr(VI), it was found that 0.5 μM had negligible effects on the cell viability of BEAS-2B cells. The expression of SEMA4B was observed to decrease in BEAS-2B cells after 7 days of treatment with 0.5 μM Cr(VI), and this downregulation continued with increasing passages of Cr(VI) treatment. Chronic expo...

Trace elements in commercially available infant formulas in Iran: Determination and estimation of health risks
The objective of the present study was to ascertain the concentrations of some trace elements namely; arsenic, cadmium, chromium, copper, nickel and lead in infant formulas sold in Iran and to estimate the potential health risks to the infants through consumption of these products. The mean concentrations of As, Cd, Cr, Cu, Ni and Pb in infant formula samples were 0.006, 0.040, 0.3980, 2.014, 0.166 and 0.285 mg/kg, respectively. The mean levels of the trace elements were in the following order: Cu > Cr > Pb > Ni > Cd > As. For arsenic, cadmium and copper, calculated EWIs (estimated weekly intakes) were withi...

Joint and interactive effects of metal mixtures on liver damage: Epidemiological evidence from repeated-measures study
CONCLUSION: Exposure to heavy metals (Cr, Cd, Mn, Pb) is associated with liver function markers, potentially leading to liver damage. Moreover, there are joint and interaction effects among these metals, which warrant further investigation at both the population and mechanistic levels.PMID:38461577 | DOI:10.1016/j.ecoenv.2024.116178 (Source: Ecotoxicology and Environmental Safety)

Genes, Vol. 15, Pages 349: A Single-Cell Transcriptome of Bovine Milk Somatic Cells
In this study, we analyzed the milk transcriptome at the single-cell level by conducting scRNA-seq analysis on milk samples from two Holstein Friesian cows at mid-lactation (75 and 93 days) using the 10× Chromium platform. Cells were pelleted and fat was removed from milk by centrifugation. The cell suspension from each cow was loaded on separate channels, resulting in the recovery of 9313 and 14,544 cells. Library samples were loaded onto two lanes of the NovaSeq 6000 (Illumina) instrument. After filtering at the cell and gene levels, a total of 7988 and 13,973 cells remained, respectively. We were able to r...

Evidence for chromium crosses blood brain barrier from the hypothalamus in chromium mice model
Ecotoxicol Environ Saf. 2024 Mar 8;273:116179. doi: 10.1016/j.ecoenv.2024.116179. Online ahead of print.ABSTRACTIt has been shown that exposure to hexavalent Chromium, Cr (Ⅵ), via nasal cavity can have neurotoxicological effects and induces behavioral impairment due to the fact that blood brain barrier (BBB) does not cover olfactory bulb. But whether Cr (Ⅵ) can cross the BBB and have a toxicological effects in central nervous system (CNS) remains unclear. Therefore, we investigated the effects of Cr (Ⅵ) on mice treated with different concentrations and exposure time (14 days and 28 days) of Cr (Ⅵ) via intraperitone...
