Abstract
Due to the development of industries such as mining, smelting, industrial electroplating, tanning, and mechanical manufacturing, heavy metals were discharged into water bodies seriously affecting water quality. Bamboo charcoal, as an environmentally friendly new adsorbent material, in this paper, the virgin bamboo charcoal (denoted as WBC) was modified with different concentrations of KMnO4 and NaOH to obtain KMnO4-modified bamboo charcoal (KBC) and NaOH-modified bamboo charcoal (NBC) which was used to disposed of water bodies containing Cu2+ and Zn2+. The main conclusions were as following: The adsorption of Cu2+ by WBC, KBC and NBC was significantly affected by pH value, and the optimum pH was 5.0. Differently, the acidity and alkalinity of the solution doesn't effect the adsorption of Zn2+ seriousely. Meanwhile, surface diffusion and pore diffusion jointly determine the adsorption rate of Cu2+ and Zn2+. The test result of EDS showed that Mn-O groups formed on the surface of K6 (WBC treated by 0.06 mol/L KMnO4) can promote the adsorption of Cu2+ and Zn2+ at a great degree. The O content on N6(WBC treated by 6 mol/L NaOH) surface increased by 30.95% compared with WBC. It is speculated that the increase of carbonyl group on the surface of NBC is one of the reasons for the improvement of Cu2+ and Zn2+ adsorption capacity. Finally, the residual concentrations of Cu2+ and Zn2+ in wastewater are much lower than 0.5 mg/L and 1.0 mg/L, respectively. Thus it can be seen, KBC and NBC could be a promising adsorbent for heavy metals.

Abstract
Despite existing studies exploring the association between metal exposure and gestational diabetes mellitus (GDM), most of them have focused on a single metal or a small mixture of metals. Our prospective work investigated the joint and independent effects of early gestational exposure to 17 essential and nonessential metals on the GDM risk and potential mediation by plasma phospholipid fatty acids (PLFAs) based on a nested case-control study established with 335 GDM cases and 670 randomly matched healthy controls. The Bayesian kernel machine regression (BKMR) and quantile g-computation analyses demonstrated a joint effect from metal co-exposure on GDM risk. BKMR with hierarchical variable selection indicated that the group of essential metals was more strongly associated with GDM than the group of nonessential metals with group posterior inclusion probabilities (PIPs) of 0.979 and 0.672, respectively. Cu (0.988) and Ga (0.570) had the largest conditional PIPs within each group. We also observed significant mediation effects of selected unsaturated PLFAs on Cu-GDM and Ga-GDM associations. KEGG enrichment analysis further revealed significant enrichment in the biosynthesis of unsaturated PLFAs. C18:1 n-7 exhibited the largest proportion of mediation in both associations (23.8 and 22.9%). Collectively, our work demonstrated the joint effect of early gestational metal exposure on GDM risk and identified Cu and Ga as the key species to the joint effect. The findings lay a solid ground for further validation through multicenter investigations and mechanism exploration via laboratory studies.

Abstract
We report the characteristics and possible impact of leachate on quality of groundwater in the Chunga Landfill area of Lusaka, Zambia. Water and leachate samples were collected within and around the landfill for analysis. The pH, biological oxygen demand (BOD), chemical oxygen demand (COD), nitrates, sulphates, chlorides for the leachate and groundwater samples were (6.6 ± 0.1 to 8.7 ± 0.0), (1.7 ± 0.3 to 1,569.6 ± 4.9 mg/L), (4.0 ± 0.0 to 10,378.5 ± 59.2 mg/L), (8.0 ± 0.0 to 37.7 ± 0.4 mg/L), (11.7 ± 0.0 to 273.1 ± 1.7 mg/L), (43.0 ± 1.2 to 974.2 ± 0.8 mg/L) respectively. Heavy metal concentration ranges were cadmium (0.004 ± 0.000 to 1.149 ± 0.021 mg/L, chromium (0.007 ± 0.000 to 2.699 ± 0.039 mg/L), copper (0.013 ± 0.002 to 0.246 ± 0.005 mg/L), lead (0.062 ± 0.005 to 2.591 ± 0.065 mg/L) and zinc (0.008 ± 0.001 to 2.032 ± 0.017 mg/L). The pH of the leachate (8.5 ± 0.0 to 8.7 ± 0.0) meant the landfill was in the methane fermentation phase. An indexing approach was used with the leachate pollution index (LPI) of 30.173, heavy metal pollution index (HPI) of 3,938.92. The heavy metal index (HMI) for copper, lead, chromium, cadmium and zinc were found to be 0.92, 1,124.19, 47.20, 994.17 and 1.48 respectively. Principal component analysis (PCA) showed that anthropogenic activities contributed to pollution with high loading values. Ash from continuous burning of the waste may provide alkalinity which reduces leachate BOD and COD. Results showed that the landfill has outgrown the designed cells capacity as not all leachate was collected by the under-drainage. Results also showed that lack of adequate landfill cover significantly increases rainfall infiltration thereby increasing volumes of leachate produced with a, hence potential for underground water contamination and a human health and environmental problem.

Copper exposure for 30 days at a daily dose twice the recommended increases blood pressure and cardiac contractility. Life Sci 2022; 300:120579. [PMID: 35489564 DOI: 10.1016/j.lfs.2022.120579] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 04/19/2022] [Accepted: 04/21/2022] [Indexed: 11/21/2022]
Abstract
Copper is an essential factor for the body's homeostasis. However, excess copper compromises organic functions. AIMS We investigated the effects of copper exposure for 30 days on blood pressure (BP) and cardiac contractility and the putative involvement of nitric oxide (NO) and reactive oxygen species. MAIN METHODS Wistar rats (12 weeks old, 280 g) were randomized to the treated group that was exposed for 30 days to copper (2000 μg/kg/day CuCl2) and the control (Ct) group that received intraperitoneal saline (0.9%). KEY FINDINGS The blood concentration of copper was ~1.26 μg/mL in the copper-exposed group and ~0.024 μg/mL in the Ct group. The main metal accumulations occurred in the liver and kidneys. Copper exposure increased systolic BP (Cu: 141 ± 3 mmHg; Ct: 133 ± 3 mmHg) (tail cuff method), left ventricular systolic pressure and papillary muscle force. Calcium release from the sarcoplasmic reticulum was reduced. The contractile response to Ca2+ was increased by copper, and the effect was not altered by L-NAME. Copper increased contractions dependent on sarcolemmal Ca2+ influx, and this effect was not altered by L-NAME. The percentage response to isoproterenol decreased in the copper-exposed group, but L-NAME did not alter this reduction. Papillary force development at the peak and plateau of tetanic contractions also increased after copper exposure, but this effect was not altered by L-NAME. In situ detection of OH local production increased. SIGNIFICANCE Copper increased BP and cardiac force, increased Ca2+ inflow, reduced Ca2+ reuptake by the sarcoplasmic reticulum, and increased OH local production. Copper exposure at doses considered tolerable affects cardiac contractility.

Abstract
This study was conducted to investigate the effects of hot-melt extrusion (HME)-processed copper (Cu) sulfate supplementation on the growth performance, gut microbiota, metabolic function of Cu, and bioavailability of Cu in weanling pigs fed a corn-soybean meal basal diets. A total of 180 piglets (Yorkshire × Landrace × Duroc) of mixed-sex randomly were allotted to six treatments on the basis of initial average body weight (6.36 ± 0.39 kg) to six dietary treatments. There were six replicates in each treatment with 5 pigs per replicates. The dietary treatments included levels of CuSO4 (IN6, 6 mg Cu/kg diets; IN125, 125 mg Cu/kg diets), nano-CuSO4 (HME6, 6 mg Cu/kg diets; HME65, 65 mg Cu/kg diets; and HME125, 125 mg Cu/kg diets), and Cu-methionine (ORG125, 125 mg Cu/kg diets). The weanling pigs fed diets supplemented with the HME65 and HME125 showed a greater body weight and feed intake compared with IN6 and IN125 (P < 0.05). The weaning pigs fed diets supplemented with the HME125 showed the highest digestibility of gross energy in phase 1 and phase 2 (P < 0.05). The supplementation of HME125 significantly reduced the Escherichia coli (E.coli) in cecum and colon (P < 0.05). The supplementation of HME65 showed statistically equivalent effect on reduction of E. coli in the cecum and colon compared with IN125 and ORG125 treatments. The villus height in duodenum and jejunum of piglets in HME65 and HME125 treatments were higher than ORG125, HME6, IN6, and IN125 (P < 0.05). The gene expression of Atox1 was upregulated in IN125, HME125, and ORG125 treatments (P < 0.05). The expression of Sod1 was increased in IN125 treatment compared with IN6 treatment (P < 0.05). The HME125 treatment had the highest gene expression of ghrelin (P < 0.05). The Cu concentration of serum and liver was higher in the HME125 treatment than the HME6, IN6, and IN125 treatments (P < 0.05). The HME125 and ORG125 treatments showed a lower fecal Cu compared with IN125 treatment (P < 0.05). Taken together, these results suggest that the HME65 can be an alternative to IN125 in weanling pigs due to the greater overall average daily gain, improved villus height, and higher bioavailability.

Abstract
BACKGROUND Excess copper (Cu) is an oxidative stress factor which associates with a variety of diseases. The aim of this study was to evaluate the effect of Cu in primary chicken embryo hepatocytes (CEHs). METHODS CEHs were isolated from 13 days old chicken embryos and followed by different concentration Cu (0, 10, 100, 200 μM) and/or ALC treatment (0.3 mg/mL) for 12 or 24 h. The effects of Cu exposure in CEHs were determined by detecting reactive oxygen species (ROS), malondialdehyde (MDA), mitochondrial membrane potential (MMP), and ATP levels. The expression of mitochondrial dynamics-related genes and proteins were also detected. RESULTS Results showed that Cu treatment (100 or 200 μM) significantly decreased CEHs viability, MMP and ATP levels, increased ROS and MDA levels in 12 or 24 h. The up-regulated mitochondrial fission genes and protein in 100 and 200 μM Cu groups suggested Cu promoted mitochondrial division but not fusion. However, the co-treatment of ALC and Cu alleviated those changes compared with the 100 or 200 μM Cu groups. CONCLUSION In conclusion, we speculated that Cu increased the oxidative stress and induced mitochondria dysfunction via disturbing mitochondrial dynamic balance in CEHs, and this process was not completely reversible.

Abstract
To explore the relationship of oxidative stress and TGF-β 1/Smad3 pathway in the inhibition of osteoblast mineralization by copper chloride (CuCl2), the osteoblasts were treated with CuCl2 (0, 50 μM, 100 μM, 150 μM CuCl2 5H2O) for 24 h. We found that Cu impaired the osteoblast structure, inhibited the glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities, alkaline phosphatase (ALP) content, mRNA expression of collagen I (COL-I), osteocalcin (OCN), insulin-like growth factor I (IGF-I), bone morphogenetic protein-2 (BMP-2), transforming growth factor β1 (TGF-β1) and core-binding factor α1 (Cbfα1), promoted the reactive oxygen species (ROS) production, inactivated the TGF-β1/Smad3 pathway. It indicates that the inactivated TGF-β1/Smad3 pathway leads to osteoblast impairment by CuCl2. It will contribute to clarify the influence of CuCl2 on the osteoblast mineralization.

Abstract
Cadmium-quantum dots (Cd-QDs) possess unique properties as optoelectronic devices for sensitive detection in food and biomedicine fields. However, the toxic effects of Cd-QDs to single cells is still controversial, due to the release mechanism of QDs to Cd2+in situ and the cytotoxic effects of QDs and Cd2+ respectively are still unclear. In this paper, the release rule of Cd2+ from CdTe QDs within single cells was investigated in situ by using flow cytometry method and the dose-response relationships were explored. Besides, an all-inclusive microscopy system was optimized for live cell imaging to observe the real-time entry process of CdTe QDs into cells. We found that intracellular CdTe QDs and Cd2+ contents were increased based on the dosage and exposing time. A dissociated saturation of Cd2+ from CdTe QDs was exist within cells. CdTe QDs induced more serious cytotoxicity on kidney cells than hepatocytes. The toxicity of oxidative stress, cell apoptosis effects induced by CdTe QDs and Cd2+ are also in consistent with this result. This research develops analytical method to quantify the uptake and release of Cd-QDs to primary cells in situ and can provide technical support in studying the cytotoxicity portion contributed by nanoparticles (NPs) and metal ions.

Abstract
BACKGROUND In this work, we investigated the antioxidant and copper chelating abilities of theaflavin, a polyphenol responsible for astringency, color, and sensation in black tea. Using voltammetric techniques, the analyses were conducted with disposable electrochemical printed carbon chips in conjunction with a portable hand-held potentiostat. RESULTS Voltammograms of theaflavin showed five separate oxidation peaks, corresponding to the oxidation of five individual functional groups. Electroanalytical data indicated that, after interaction with copper, theaflavin had higher antioxidant potential and was a better copper chelator than epigallocatechin gallate, a major polyphenol present in green tea and a well-known antioxidant. This could be attributed to the extra fused ring and larger number of OH groups in theaflavin. CONCLUSIONS Our findings introduce another natural compound as a potential nutraceutical in oxidation- and copper-modulated illnesses. This simple and fast approach would also be highly pertinent to the inspection of the health benefits of natural food products. To the best of our knowledge, this is the first report of the electrochemical analysis of Cu (II) chelation with theaflavin. © 2020 Society of Chemical Industry.

Abstract
For assessment of the modern situation about the choice of materials for manufacture of dental implants and the processing of their surface the scientific literature for the last 2 years was study. On the basis of a large number of contradictory results of the researches devoted to each of dental implantation problems it is possible to draw a conclusion that any of primal problems of implantology is finally not solved. There is no unique opinion at the choice of optimum material for manufacture of dental implants, at the way of processing and modification of their surface. The problem of improvement of quality of dental implantation and fight against complications of this procedure cannot be solved simple drawing other substances on the implanted material surface, this task more easily and more successfully is solved via changes of product structure and various modification of implant surface. Up to the present the researches of an opportunity to influence on characteristics of the implanted materials, changing their structure and character of a surface, continue. And the publications reporting about the considerable positive effect of artificially created roughnesses on product surfaces, and the articles claiming that there are no big differences between the rough and polished implants are confirmed by objective measurements with statistical processing of the obtained data. It should be noted that among articles there are very many works of the doubtful plan or with insufficiently valid conclusions. This review leads to the conclusion that further clinical and experimental studies and about the choice of materials for manufacture of implants and at the ways of processing of their surface are necessary.

Abstract
Arsenic or copper is one of the most highly toxic pollution that can cause dysfunction to brains, however, the exact mechanism remains unclear. The aim of the study is to investigate the mechanisms of arsenic or/and copper-induced oxidative stress, inflammation and autophagy in chicken brains and elucidate the interactions between arsenic and copper. A total of 72 1-day-old Hy-line chickens were divided into four groups (18 chickens per group) treated with 30mg/kg arsenic trioxide (As2O3) or/and 300mg/kg copper sulfate (CuSO4) for 12weeks. Histological signs of inflammation were found in the cerebrum, cerebellum and brainstem exposure to arsenic or/and copper. The malondialdehyde (MDA) content were up-regulation, whereas oxidative damage parameters total antioxidant capacity (T-AOC), glutathione (GSH), the inhibition ability of hydroxyl radical (OH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were significantly decreased (P<0.05). The mRNA levels and protein expressions of inflammation markers, such as nuclear factor kappa B (NF-κB), tumor necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-2) and prostaglandin E synthase (PTGEs) were significantly increased (P<0.05). The mRNA levels and protein expressions of autophagy markers including phosphatidylinositol 3-kinase (PI3K), Akt, autophagy-related gene 5 (ATG5), microtubule-associated protein light chains 3 (LC3), ATG4B, and Becline1 in different regions of brains were up-regulation (P<0.05), except the mammalian target of rapamycin complex (mTORC). In conclusion, we speculated that arsenic or copper could induce oxidative stress, inflammation and autophagy in chicken brains, and there may have a synergistic effect between copper and arsenic.
