Ferrocene-Based N-Heterocyclic Silylenes: Monomeric Silanechalcogenones, Silanimines, Silirenes, and Insertion Products with P4
Chemistry. 2024 Apr 24:e202400850. doi: 10.1002/chem.202400850. Online ahead of print.ABSTRACTThe stable ferrocene-based N-heterocyclic silylenes fc[(N{B})2Si] (A; fc = 1,1'-ferrocenylene, {B} = (HCNDipp)2B, Dipp = 2,6-diisopropylphenyl) and fc[(NDipp)2Si] (B) are compared in a study focussing on their reactivity towards a range of small to moderately sized molecular substrates, viz. P4, S8, Se8, MesN3 (Mes = mesityl), RC≡CH, and RC≡CR (R = Ph, SiMe3). The Dipp-substituted congener B exhibits a more pronounced ambiphilicity and is sterically less congested than its 1,3,2-diazaborolyl-substituted relative A, in line wit...

Synergistic antimicrobial action of nanocellulose, nanoselenium, and nanocomposite against pathogenic microorganisms
In this study, nanocellulose was extracted from algae, biomolecule substances synthesized selenium nanoparticles, and a simple nanocomposite of nanocellulose and nanoselenium was elaborated using nanocellulose as a reducing agent under hydrothermal conditions. These nanocomposite materials have markedly improved properties at low concentrations. Our obtained polymers were characterized using techniques including Fourier-transform infrared spectroscopy, X-ray powder diffraction, Thermo gravimetric analysis (TGA), Scanning electron microscopic (SEM), Energy Dispersive X-ray analysis (EDX), Transmission electron microscopic (...

GSE173219 High-throughput sequencing of oxidative stress for Human gastric cancer cell lines treatment with Bioactive polypeptide chelating selenium (ACBP-S-Se)
Contributor : Xiulan SuSeries Type : Expression profiling by high throughput sequencing ; Non-coding RNA profiling by high throughput sequencingOrganism : Homo sapiensThe functional gene analyses revealed 911 upregulated genes and 1122 downregulated genes after ACBP-S-Se treatment in MKN-45 cells. From the functional enrichment analyses of oxidative stress-related genes, a total of 75 genes with significant differences were selected . From the gene interaction mapping, CDKN1A, CCNB1, TXN and MAP3K5 were extracted due to the roles of most genes with which they associate and to the significantly enriched pathways, which can...

Associations among environmental exposure to trace elements and biomarkers of early kidney damage in the pediatric population
Conclusions. Among the explored metals, exposure to Cu and iodine impairs renal function. In contrast, Se may manifest as a beneficial metal. Interactions of Mo-Se and Mo-Iodine seem to alter the expression of NGAL; Mo-Cu for CLU; Mo-Cu, Mo-Se, and Mo-iodine for Cys-C and a-1MG; and Mo-Cu and Mo-iodine for KIM-1; were noticed. Our study could suggest that trace element interactions were associated with early kidney damage biomarkers.PMID:38642266 | DOI:10.1007/s10534-024-00603-3 (Source: Biometals)

Elemental Composition of Toxic and Essential Elements in Rice-Based Baby Foods from the United States and other Countries: A Probabilistic Risk Analysis
Food Chem Toxicol. 2024 Apr 17:114677. doi: 10.1016/j.fct.2024.114677. Online ahead of print.ABSTRACTConsumption of rice-based foods provides essential nutrients required for infants and toddlers' growth. However, they could contain toxic and excess essential elements that may affect human health. The study aims to determine the composition of rice-based baby foods in the USA and outside and conduct a multiple-life stages probabilistic exposure and risk assessment of toxic and essential elements in children. Elemental concentrations were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in thirty-three r...

Impact of different forms of selenium supplementation on growth and physiological performance of New Zealand white rabbits
AbstractForty-eight weaned male New Zealand White rabbits aged 6 weeks with an initial body weight of (709.67 ± 13 g) were randomly divided into six experimental groups (8 rabbits each) for 6–14 weeks of age experimental periods. The present study was planned to evaluate the effect of using different forms of Selenium element (inorganic, nanoparticles and organic) as dietary supplementation on productive performance of rabbits. Six experimental groups in completely randomized design were used. The first group (G1, control) was fed the basal diet to cover maintenance and production allowances. Rabbits in the othe...

Continuous selenite biotransformation and biofuel production by marine diatom in the presence of fulvic acid
In this study, the biochemical response of Phaeodactylum tricornutum to varying concentrations of inorganic selenium (Se) was investigated. It was observed that, when combined with fulvic acid, P. tricornutum exhibited enhanced uptake and biotransformation of inorganic Se, as well as increased microalgal lipid biosynthesis. Notably, when subjected to moderate (5 and 10 mg/L) and high (20 and 40 mg/L) concentrations of selenite under fulvic acid treatment, there was a discernible redirection of carbon flux towards lipogenesis and protein biosynthesis from carbohydrates. In addition, the key parameters of microalgae-based bi...
