Abstract
Drosophila melanogaster DAxud1 is a transcription factor that belongs to the Cysteine Serine Rich Nuclear Protein (CSRNP) family, conserved in metazoans, with a transcriptional transactivation activity. According to previous studies, this protein promotes apoptosis and Wnt signaling-mediated neural crest differentiation in vertebrates. However, no analysis has been conducted to determine what other genes it might control, especially in connection with cell survival and apoptosis. To partly answer this question, this work analyzes the role of Drosophila DAxud1 using Targeted-DamID-seq (TaDa-seq), which allows whole genome screening to determine in which regions it is most frequently found. This analysis confirmed the presence of DAxud1 in groups of pro-apoptotic and Wnt pathway genes, as previously described; furthermore, stress resistance genes that coding heat shock protein (HSP) family genes were found as hsp70, hsp67, and hsp26. The enrichment of DAxud1 also identified a DNA-binding motif (AYATACATAYATA) that is frequently found in the promoters of these genes. Surprisingly, the following analyses demonstrated that DAxud1 exerts a repressive role on these genes, which are necessary for cell survival. This is coupled with the pro-apoptotic and cell cycle arrest roles of DAxud1, in which repression of hsp70 complements the maintenance of tissue homeostasis through cell survival modulation.

Abstract
With the increasing application of cerium and rare-earth elements (REEs), cerium exposure is becoming more widespread. However, there remains a paucity of evidence on developmental immunotoxicity of cerium. This study was designed to examine the developmental immunotoxicity of gestational and postnatal exposure to cerium nitrate (CN) in BALB/C mouse offspring. Dams were given CN by oral gavage at 0, 0.002, 0.02 and 0.2 mg/kg from gestation day 5 (GD5) to postnatal day 21 (PND 21). On PND 21, the highest dose of CN significantly suppressed the NK cell cytotoxicity, and reduced the proportions of NK cells in peripheral blood and spleen of both female and male pups, however, the proportions of monocytes in peripheral blood and macrophages in spleen only increased in female pups. For adaptive immunity, on PND 21, the suppression of T/B lymphocyte proliferation, humoral and cellular immune responses (number of splenic plaque-forming cells, PFC, and delayed-type hypersensitivity, DTH) were observed in both female and male pup mice exposed to 0.2 mg/kg CN. However, the fall of proportions of T/B lymphocytes in peripheral blood (PB), spleen and mesenteric lymph node (MLN) only found in female pups at 0.2 mg/kg on PND 21. Most indications recovered to normal after 3-week cessation of CN exposure, except the reduction of DTH and PFC. From the findings in this study, the lowest-observed-adverse-effect level (LOAEL) of CN for developmental immunotoxicity was estimated to be 0.2 mg/kg bw per day.

Abstract
Cerium is a critical element to modern technologies. Nowadays, its increased applications have led to elevated levels in the environment. Cerium recovery by microorganisms has gained a great deal of attention. Here, our research showed that Bacillus licheniformis could be used to recover Ce3+ from aqueous solution. The adsorption capacity of cerium on this bacterial strain achieved 38.93 mg/g (dry weight) biomass. Adsorption kinetics followed a pseudo-second-order rate model, and adsorption isotherm was fitted well with the Freundlich model. Scanning electron microscope (SEM) observations coupled with X-ray energy dispersive spectroscopy (EDS) analysis revealed a spatial association of Ce with C, N, O, S, and P. Fourier transform infrared spectroscopy (FT-IR) analysis further suggested that the phosphate and carboxyl groups on the cell surface might be responsible for the adsorption of cerium. Furthermore, X-ray diffraction (XRD) and transmission electron microscopy (TEM) with electron energy loss spectroscopy (EELS) suggested that cerium initially occurred on the bacterial cell surface as Ce(OH)3, which was mainly converted to monazite (CePO4) and a small amount of CeO2 overtime. Hydrothermal treatment was used to accelerate the mineralization process of cerium by B. licheniformis. The hydrothermal treatment is conducted for comparative analysis of mineralization process in extreme geological condition.

Abstract
The human biological monitoring of metals (metalloids) is of importance, which concentrations could indicate a wide range of health related information. Reference values (RVs) of metals (metalloids) in specific matix of populations are critically required when performing a statistical evaluation accurately. Recent studies show that RVs of metals (metalloids) are influenced by many multiple factors, including lifestyle, diet, dissimilar environment, location, as well as race. However, it is virtually absent across many nations/regions, especially multi-race coexistence regions. The aim of the work was to establish RVs of metals (metalloids) in urine of adult in Xinjiang, China. Totally 178 urine samples from healthy volunteers were collected and analyzed by inductively coupled plasma mass spectrometer or optical emission spectrometer (ICP-MS/OES). RVs of 26 metals (metalloids) in urine for adult of Xinjiang, China were then established. Effects of race, gender and age on RVs were investigated using partial least squares discriminant analysis and student T-test. The result demonstrated that above factors showed mild influence for the establishment of RVs. The RVs derived from total 178 urine adult samples (Han and Uygur half of each) can be applied for different race, gender and age periods. Moreover, it was observed that three metals (metalloids), As, Sc and Ba significantly varied between some subgroups. The established RVs will be valuable for future health or environmental evaluation, and can serve as a theoretical reference for RVs establishment in multi-race coexistence region.

Abstract
To compare the contents of rare earth elements in urine and drinking water of children in the mining and control areas and evaluate the health risk of children in the mining area.Urine and drinking water of 128 children in the mining area and 125 children in the control area were collected from June to July 2015. The contents of rare earth elements were determined using inductively coupled plasma mass spectrometry.The detection rates of rare earth elements, including yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm), in the urine of children in the exposed group were all 100%, except for samarium (98%); the rates in the control group were 85.7%, 100%, 100%, 98%, 98%, and 59.2%, respectively, and the remaining elements were not detectable. The concentrations of Y, La, Ce, Pr, Nd, and Sm in the urine of children in the exposed group were significantly higher than that in the control group (P < .01). In addition, the composition ratio of lanthanum was higher than that in the control group. The detection rates of lanthanum and Ce in the drinking water of children in the exposed group were 1.44% and 0.72%, respectively. The others were not detectable; the rates in the control group were all 0%.The pollution caused by the presence of Y, La, Ce, Pr, Nd, and Sm in the mining area might affect the health of children in the area, but drinking water might not be the cause.

Abstract
It has been demonstrated that the organic damages of animals can be caused by exposure to lanthanide oxides or compounds. However, the molecular mechanism of CeCl3 -induced kidney injury remains unclear. In this study, the mechanism of nephric damage in mice induced by an intragastric administration of CeCl3 was investigated. The results showed that Ce(3+) was accumulated in the kidney, which in turn led to oxidative stress, severe nephric inflammation, and dysfunction in mice. Furthermore, CeCl3 activated nucleic factor κB, which in turn increased the expression levels of tumor necrosis factor α, macrophage migration inhibitory factor, interleukin-2, interleukin-4, interleukin-6, interleukin-8, interleukin-10, interleukin-18, interleukin-1β, cross-reaction protein, transforming growth factor-β, interferon-γ, and CYP1A1, while suppressed heat shock protein 70 expression. These findings implied that Ce(3+) -induced kidney injury of mice might be associated with oxidative stress, alteration of inflammatory cytokine expression, and reduction of detoxification of CeCl3 .

Abstract
Environmental pollution from lanthanides (Ln) has been recognized as a major problem due to a grab exploitation of Ln mine in China. Exposure to Ln has been demonstrated to cause the nephrotoxicity, very little is known about the mechanism of oxidative damage to kidney in animals. In order to understand Ln-induced nephrotoxicity, various biochemical and chemical parameters were assayed in mouse kidney. Intragastric exposures of LaCl₃, CeCl₃, and NdCl₃ at doses of 2, 5, and 10 mg kg(-1) BW for 90 consecutive days caused nephritis or epithelial cell necrosis and oxidative stress to kidney. An increase in coefficients of the kidney, La, Ce, and Nd accumulation and histopathological changes in the kidney could be observed, followed by increased reactive oxygen species production and peroxidation levels of lipid, protein and DNA, and decreased activities of superoxide dismutase, catalase, glutathione-S-transferase and glutathione reductase as well as antioxidants such as glutathione, ascorbic acid and thiol contents. Furthermore, La, Ce, and Nd significantly suppressed expression of genes and proteins of these antioxidative enzymes in mouse kidney. In addition, kidney functions were disrupted, including an increase of the creatinine, and reductions of uric acid, urea nitrogen, calcium and phosphonium. These findings suggest that nephritis generation or epithelial cell necrosis in mice following exposure to Ln is closely associated with oxidative stress. Of these damages, the most severe was in the Ce(3+)-exposed kidneys, next in the Nd(3+)-exposed kidneys, and the least in the La(3+)-exposed kidneys, which may be attributed to the 4f electron of Ln.
