Based on these results, our study suggests that SLC34A2 promotes cancer proliferation and cell cycle progression by targeting TMPRSS3 in colorectal cancer cells.Medullary thyroid cancer (MTC) is the third frequent subtype of thyroid cancer-driving from thyroid C-cells. The first-line strategy to treat MTC is surgery, but tumor recurrence and patients' mortality rate have still been demonstrated in approximately 4-10% of MTC cases. Therefore, to treat and prevent the progressive form of the disease, the early diagnosis of MTC is assumed to play a critical role. In this regard, recently, circulating biomarkers have drawn researchers' attention for their nonaggressive manners in the sample collection. In this systematic review, we aimed to focus on circulating biomarkers and their applications in MTC diagnosis, prognosis and follow-up, and we discussed their clinical application and how they can affect clinical decision making in the future. A literature search (from 2000 to 2021) was accomplished on MTC circulating biomarkers in different databases, and only English articles were evaluated. We found that calcitonin (CT) and carcinoembryonic antigen (CEA) are the most important circulating biomarkers in the MTC diagnosis. Other circulating biomarkers included pro-calcitonin (Pro-CT), pro-Gastrin releasing peptide (Pro-GRP), carbohydrate antigen 19-9 (CA 19-9) and chromogranin A (CgA). Some novel circulating biomarkers comprised vaspin and retinol-binding protein-4 (RBP4), myostatin, tumor cells (CTCs), RET M918T mutated cfDNA, circulating tumor DNA (ctDNA), miR-375 and Alu83 and Alu244 cfDNAs. Several circulating biomarkers have been identified to optimize the accuracy of diagnosis and offer new prognostic criteria, which should be verified before any clinical application. Although different circulating biomarkers contributed to MTC have been discovered, a few of them could be used in clinical diagnosis. In many cases, the application of each marker may not be useful lonely; therefore, a combination of two or more biomarkers could open a new avenue in the diagnosis, prognosis and prediction of MTC.

Spindle Cell Carcinoma (SpCC) is a rare type of squamous cell carcinoma (SCC) with prominent malignant spindle cell component. This unique biphasic feature on histopathological examination makes its diagnosis problematic. Detection of p63 antigens in SpCC can be helpful however its expression in variousb proliferating soft tissue lesions demands for better marker.

In this study, histopathologically diagnosed SpCC of head and neck region were considered as cases, and 22 soft tissue sarcomas, reactive lesions and spindle cell lesions of the body were taken as controls. Immunohistochemistry (IHC) was done using Anti-p63 and p40 clone and the results were compared. 5-(N-Ethyl-N-isopropyl)-Amiloride CK was done for negative cases to prove their epithelial origin. P. value <0.05 considered statistically significant.

Among 22 cases of SpCC, 19 cases showed positive immunoreactivity to p63, and 18 cases for p40. IHC of controls showed no immunoreactivity in any of the sarcomas, reactive lesions or spindle cell lesions. The sensitivity of p63 is 86% while that of p40 is 82%. Specificity of both the markers was 100% CONCLUSION Though p63 is a slightly (4%) more sensitive marker than p40, percentage of cell positivity for p40 is higher compared to p63. Both of these markers are 100% specific for SpCC.

Among thymic tumors, sebaceous glands are a relatively common component of mediastinal teratomas but are exceedingly rare in other neoplasms of thymic origin. This review explores the spectrum of non-teratomatous thymic tumors in which sebaceous differentiation has been identified, discusses the potential histogenesis and evaluates the effects of this occurrence on diagnosis, treatment and prognosis.The salvaging of the waste disposable mask was conducted in this study through catalytic pyrolysis over corn stover derived biochar catalyst combined with the boosted generation of hydrogen and mono-aromatic hydrocarbons for the first time. In the absence of biochar, up to 53 wt% of wax was observed at 550 ºC, whereas at the biochar/mask ratio of 2, around 41 wt% of liquid oil was produced without the formation of wax. The hydrogen content in the gas stream was about 26 vol% at 600 ºC for non-catalytic pyrolysis, which increased to around 55 vol% at the expense of light hydrocarbons such as methane and C2-4 for the catalytic process with the biochar/mask ratio of 3. In resulting liquid oil, the content of mono-aromatics, especially toluene, xylenes, and ethylbenzene was about 55% for catalytic runs, which was far greater than that of 38% from the non-catalytic run. Interestingly, the dyes released from mask pyrolysis could be completely captured/adsorbed by biochar, leading to a much cleaner oil. After 10 cycles of reuse at 600 ºC without regeneration, the biochar still held a good selectivity toward hydrogen and mono-aromatic hydrocarbons. This study exemplified a readily accessible concept and pathway of 'waste against waste' targeted to upcycle waste disposable masks over biochar from biomass waste.Nitrosamine by-products in drinking water are designated as probable human carcinogens by the IARC, but the health effects of simultaneous exposure to multiple nitrosamines in drinking water remain unknown. Genotoxicity assays were used to assess the effects of both individual and mixed nitrosamines in finished drinking water produced by a large water treatment plant in Shanghai, China. Cytotoxicity and genotoxicity were measured at 1, 10-, 100- and 1000-fold actual concentrations by the Ames test, Comet assay, γ-H2AX assay, and the cytokinesis-block micronuclei assay; oxidative stress and the Nrf2 pathway were also assessed. Nitrosamines detected in drinking water included NDMA (36.45 ng/L), NDPA (44.68 ng/L), and NEMA (37.27 ng/L). Treatment with a mixture of the three nitrosamines at 1000-fold actual drinking-water concentration induced a doubling of revertants in Salmonella typhimurium strain TA100, DNA and chromosome damage in HepG2 cells, while 1-1000-fold concentrations of compounds applied singly lacked these effects. Treatment with 100- and 1000-fold concentrations increased ROS, GSH, and MDA and decreased SOD activity. Thus, nitrosamine mixtures showed greater genotoxic potential than that of the individual compounds. link2 N-Acetylcysteine protected against the nitrosamine-induced chromosome damage, and Nrf2 pathway activation suggested that oxidative stress played pivotal roles in the genotoxic property of the nitrosamine mixtures.The phosphonate functionalized layered double hydroxide constructed through intercalation reaction, and efficiently applied to capture toxicant metal ions. The characterization results indicated that the functionalized composite with many functional groups has adsorption potential to heavy metals. The strong chelation of the phosphonate groups with heavy metal ions proved it an excellent adsorbent leading to a maximum adsorption capacity of 156.95 mg/g (Cr3+) and 198.34 mg/g (Cd2+) separately. The data of kinetics and isotherm revealed that the chelating adsorption was dominated by chemisorption and monolayer interaction. Notably, the spent adsorbent presented satisfactory reusability after six cycles. Furthermore, the Forcite simulation with the CLAYFF-CVFF force field implied that the critical mechanism for modifiers and the surface sites of the interlayer is electrostatic interaction. Our in-depth exploration in terms of the weak interactions not only demonstrated the strength and nature but also provided a novel way to intuitively capture the type of interactions that occurred around interesting regions. In the end, we made detailed investigations on the chelation mechanism, and the covalent nature played a leading role in the binding interaction. This work provides a valuable strategy for researchers to design novel materials in practice.The dissimilatory Fe(III)-reducing bacteria play a significant role in the mobility of antimony (Sb) under reducing environment. Sb-rich smelting slag is iron (Fe)-containing antimonic mine waste, which is one of the main sources of antimony pollution. In this study, the soluble antimony reacted with Fe(III) by S. oneidensis (Shewanella oneidensis strain MR-1) was performed in reduction condition, then the dissolution behavior of the Sb-rich smelting slag with S. oneidensis was investigated. The results showed that the released Sb was immobilized by S. oneidensis and the strain adsorbed Sb(III) preferentially. Sb(V) can be reduced by S. oneidensis without aqueous Fe. In the presence of Fe(III), S. oneidensis mediated Sb bio-adsorption and the chemical redox of Sb-Fe occurred simultaneously. Sb was co-precipitated with Fe to form the Sb(V)-O-Fe(III) secondary mineral, which was identified as the bidentate mononuclear edge-sharing structure by extended X-ray absorption fine structure (EXAFS) analysis. These results suggest that S. link3 oneidensis has a positive effect on the immobilization and minimizing toxicity of antimony in anoxic soil and groundwater, which provides a theoretical basis for the treatment of antimony contamination.This study investigated whether treatment with plant-based polyphenols (PB-P) affected the biochemical and/or biomechanical properties of dentin extracellular matrix (ECM). Three PB-Ps were evaluated luteolin (LT), galangin (GL), and proanthocyanidin (PAC). Because dentin ECM requires demineralization before treatment, this study also assessed the effect of these PB-Ps on dentin demineralized by two different chemicals. Dentin samples from extracted third molars were obtained, sectioned, and randomly assigned for demineralization with either phosphoric acid (PA) or ethylenediaminetetraacetic acid (EDTA). Following demineralization, baseline infrared (IR) spectra and apparent elastic modulus (AE) of each specimen were independently acquired. Based upon these initial tests, samples were randomly assigned to one of the PB-P treatments to ensure that distribution of baseline AE was similar across treatment groups. IR and AE specimens were individually immersed in either 0.2% LT, 0.4% GL or 1% PAC for 2 min. IR spectra of treated samples were compared to baseline IR spectra, looking for any interaction of PB-Ps with the demineralized dentin. The IR spectrum and AE of each PB-P-treated specimen were compared with their own correspondent baseline measurement. The ability of PB-Ps to inhibit proteolytic activity of dentin ECM was assessed by the hydroxyproline assay. Finally, the effect of PB-Ps on immediate bond strength of a dental adhesive to PA- or EDTA-etched dentin was also evaluated. PB-Ps exhibited distinctively binding affinity to dentin ECM and promoted significant increase in AE. PB-P treatment reduced the degradation rate of dentin ECM without causing detrimental effect on immediate bond strength to dentin. Our work represents the first-time that LT and GL have been assessed as dentin ECM biomodifiers.
