Among heavy metals, essential metal elements explained more rates of bacterial variation than toxic metals at moderate contaminant levels. Moreover, the bacteria with multiple metal resistances identified in culture-dependent experiments were probably not suitable for indicating heavy metal contamination in field research. Thus, several sensitive bacterial genera such as Rhodobacter, Hylemonella, and Dechloromonas were identified as potential bioindicators to monitor metals (iron and titanium) and nutrients (phosphorus and organic carbon) in the river ecosystem of the Panzhihua region. Together, these results profiled the coupling effect of urbanization and mineral resource utilization on shaping sediment bacterial communities in urban rivers.We investigated the abundance of microplastics in freshwater, treated water, and household tap water from the drinking water supply chain in Changsha, China. The abundance was 2173-3998 (mean = 2753), 338-400 (mean = 351.9), and 267-404 (mean = 343.5) particles L-1 in freshwater, treated water, and tap water, respectively. Fibrous and fragments made up the majority (> 70%) in all water samples, and most polymers were composed of polyethylene, polypropylene, and polyethylene terephthalate. Microplastics in tap water were related to materials of transportation pipelines in drinking-water supply chain. Although plastics are corrosion-resistant, the slight fragmentation and abrasion may occur during drinking water treatment transportation. This study provided a proof for the occurrence of microplastics in drinking water, which may offer a reference for microplastic removal during drinking water treatment, and the formulation of standards for microplastic content in drinking water.
En bloc spondylectomy is the gold standard for surgical resection of sacral chordomas (CHO), but the effect of extent of resection on recurrence and survival in patients with CHO of the cervical spine remains elusive.

MEDLINE, Embase, Scopus, and Cochrane were systematically reviewed. Patients with cervical CHO treated at three tertiary-care academic institutions were reviewed for inclusion. We performed an individual participant data meta-analysis to assess the overall survival (OS) and progression free survival (PFS) after en bloc-gross total resection (GTR) and intralesional-GTR compared to subtotal resection (STR). We then performed an intention-to-treat analysis including all patients with attempted en bloc resection in the en bloc group, regardless of the surgical margins.

There was a total of 13 series including 161 patients with cervical CHO, including our current series of 22 patients. GTR (en bloc-GTR + intralesional-GTR) was associated with a significant decrease in the risk of local progressrvical CHO. We found that both en bloc-GTR and intralesional-GTR resulted in improved local tumor control when compared to STR.
Molecular mechanisms of uveal melanoma development in association with high pigmentation are unclear. Tyrosinase Related Protein (TYRP1) is not only one of the important melanogenesis marker that contributes to melanin synthesis, but can also prevents the melanocyte death. The induction of melanogenesis leads to induction of HIF-1α which can affect the behavior of melanoma cells and its surrounding environment. The aim of our study was to determine the expression of TYRP1 and HIF-1α at the protein and RNA level and determine its prognostic significance.

In the present study, the expression of TYRP1 and HIF-1α was investigated on 61 formalin-fixed paraffin-embedded choroidal melanoma samples by immunohistochemistry. Fresh 50 samples were validated by real-time PCR. Results were correlated with clinicopathological parameters and Kaplan-Meier was performed to determine the prognostic significance.

High immunoexpression of TYRP1 and HIF-1α was present in 61 and 54% of patients, respectively. Both TYRP1 and HIF-1α correlated well with high pigmentation and BAP1 (BRCA1 Associated Protein-1) loss (p < 0.05) at IHC level as well as transcriptional level. There was reduced metastatic free survival in patients with necrosis and this was statistically significant (p = 0.010).

Our findings indicate that TYRP1 can be used as a potential biomarker in the development of targeted therapy in UM. GSK1070916 Further studies on melanogenesis markers associated with TYRP1 could provide us a better understanding in this field.

This study aimed to evaluate the psychometric properties of the 10-item and 2-item Connor-Davidson Resilience Scale (CD-RISC), the agreement between these two versions, and the measurement invariance of the CD-RISC-10 across genders in Chinese infertile couples.

A total of 170 infertile couples were enrolled from an infertility outpatient clinic between September 2019 and January 2020. The CD-RISC scores were tested for floor and ceiling effects. Reliability was evaluated by calculating Cronbach's α. Convergent and divergent validity were assessed by bivariate correlations between resilience and infertility-related stress, depression, anxiety, and two divergent variables. Agreement between the two versions was evaluated using the intraclass correlation coefficient (ICC) and Bland-Altman analysis. A multiple-group confirmatory factor analysis (CFA) was conducted to assess the measurement equivalence of CD-RISC-10 across genders.

No floor or ceiling effects were observed. Internal consistencies of CD-RISC-10 and CD-RISC-2 were 0.91 and 0.63, respectively. The CFA analysis indicated an excellent model fit for a one-factor structure of CD-RISC-10 (TLI > 0.950, CFI > 0.950, RMSEA < 0.060). Both scales displayed good convergent and divergent validity, and the agreement between them was significant with an ICC of 0.80 (95% CI ranging from 0.76 to 0.84). Measurement invariance across genders was supported by multigroup CFA, and a higher level of resilience was found in men than in women.

Our findings showed significant reliability, validity, and stability of CD-RISC-10 and acceptable internal consistency and validity of CD-RISC-2. CD-RISC-10 is recommended as a resilience measure in clinical evaluations of infertile patients.
