Perfluorinated carboxylic acids with carbon chain length > 8 decreased concentrations of RBCF to a greater degree than those carbon chain length ≤ 8. Perfluorinated chemicals with a sulfonic group with carbon chain length > 6 decreased concentrations of RBCF to a greater degree than those carbon chain length ≤ 6. The degree to which concentrations of RBCF decrease varied by age, gender, and race/ethnicity. Non-Hispanic blacks as compared to non-Hispanic whites and Hispanics had the lowest decreases in RBCF concentrations. Mechanisms responsible for negative associations between RBCF and PFAA concentrations are not known and will need to be researched further.Co-production is a paradigm shift from the traditional model of public policymaking and service delivery that advocates for the involvement and participation of end-users of services as co-partaker in the process. In this paper, we examined the emerging models of co-production in solid waste management in Nigeria using a case study methodology. Four cases were purposefully selected for detailed exploration. The results of the analysis show that the involvement of the plurality of the non-state actors in waste management co-production brought in innovation through ICT, financial resources through grants, and increased public awareness. And have also given the service receivers a change of orientation that makes them perceive waste as a source of income rather than all rubbish needed to be discarded. However, possible exploitation of informal waste pickers, unclear business models, and absence of prior arrangement for coming together of both state and non-state actors in designing the service production are challenges to the emerging co-production cases. The current study further shows that the emerging co-production efforts have huge potential in promoting circular economy as it creates a better avenue for the implementation of extended producer responsibility (EPR), the establishment of eco-industrial parks, and safe integration of informal waste recyclers.Colorectal cancer (CRC) is one of the most common cancers worldwide. Natural Killer Group 2D Receptor (NKG2D) and their ligands (NKG2DLs) play crucial roles in natural killer (NK) cell-mediated cytotoxicity. Tumorigeneses cause increased NKG2DLs expression on tumor cell surfaces, thereby these cells individually eliminated by NK cells. However, CRC cells can reduce their NKG2DL expression to escape from NK-mediated immune surveillance which is associated with poor prognosis. Therefore, previous studies suggest that up-regulation of NKG2DLs can contribute to promising NK cell-mediated immunotherapy strategies. We aimed to analyze NKG2DLs expression profiles in response to chemotherapeutic drugs and increased MHC class I polypeptide-related sequence A (MICA) expression, which is related to favorable prognosis in CRC, using low doses of bortezomib and epirubicin combination without causing direct cytotoxicity. Results showed that MICA expression sligthly increased following drug treatment in the CRC cells but not for the normal cells. Also, we enriched our study with Gene Expression Omnibus (GEO) datasets including expression profiles of various NKG2DLs using in silico analyses. Accordingly, NKG2DL expression in CRC was screened in proportion to other cancers, histologic subtypes, TNM stages and metastatic samples to compare with our data. Overall, the analyzed data showed that NKG2DLs demonstrate different expression profiles in response to chemotherapeutic agents and a combination of low-dose bortezomib and epirubicin slightly increased MICA mRNA expression in CRC cell lines. However, performing further analysis of the combination therapy for MICA protein expression and studying its interaction with NK cells will make the results more meaningful.Vaginal delivery (VD) and elective cesarean (CS) delivery modes may cause significant differences in maternal and fetal metabolism. In this study, we aimed to investigate changes in lipid metabolism, oxidative and apoptotic signaling pathways during VD and CS in maternal and cord blood and placenta tissue. The study included two groups of participants delivered via 90 CS and 90 VD. Maternal and cord blood samples were collected from the participants. In addition, placenta samples were also taken after delivery. Total oxidant (TOS), malondialdehyde (MDA), total antioxidant (TAS), glutathione (GSH), cleaved caspase 3 (CASP3) and perilipin 2 (PLIN2) levels were measured to determine oxidative stress, antioxidant levels and apoptosis status in the VD and CS groups. Besides, PLIN2 mRNA expressions in placental specimens were analyzed. We found no statistically significant difference in maternal age, body mass index, gestational age, birth weight and Apgar scores in both groups (P > 0.05). The increase in MDA, TOS, GSH and TAS levels was higher in the VD group compared to the CS group (P  less then  0.05). Similarly, PLIN2 levels and lipid profiles showed an increase in the VD group (P  less then  0.05 vs CS group). Likewise, PLIN2 expression enhanced in the VD group (P  less then  0.05 vs CS group). However, CASP3 activity reduced in maternal and cord blood in the VD group compared to the CS group. Our results support that the delivery mode may cause differences in lipid profile, oxidative and apoptotic status by affecting PLIN2 levels in both maternal and cord blood and placenta tissue.The stimulation of extracellular matrix (ECM) protein production is an interesting target to maintain normal skin structure and delay skin aging. Copper has been shown to stimulate ECM protein synthesis by activating lysyl oxidase. Although copper increases elastin and collagen synthesis, the effect of copper and amino acid mixtures on gene expression and protein synthesis changes relating to the ECM have not been fully investigated. In this study, we showed that copper ions (Cu2+) and amino acid mixtures significantly increased the expression of genes and proteins related to the ECM in human dermal fibroblasts. The expression of genes involved in ECM production was evaluated through quantitative polymerase chain reaction in the presence of amino acid mixtures containing different Cu2+ concentrations. Cu2+ dose-dependently increased the gene expression of elastin and collagen I. In addition, a mixture of amino acids and Cu2+ increased the protein expression of elastin and collagen I. We further evaluated the effect of Cu2+ with or without amino acids. Although Cu2+ treatment increased the expression of genes encoding ECM proteins, the Cu2+ treatment without amino acids did not increase protein expression in the ECM. Our results demonstrated the synergistic effects of amino acids and a Cu2+ mixture on ECM protein synthesis in dermal fibroblasts.TiO2 NPs have been investigated for their toxic potential and studies have reported their toxicity is due to generation of oxidative stress. In the present study, we investigated the toxicity of TiO2 NPs and explored the potential of well-known antioxidant coenzyme Q10 (CoQ10) in counteracting the NP-induced toxicity in isolated human blood cells. When the isolated blood cells were treated with varying concentrations of TiO2 NPs (25-100 μg/ml), only 50 μg/ml dose induced statistically significant hemolysis in erythrocytes and cytotoxicity in lymphocytes (p  less then  0.05). None of the concentrations induced any significant increase in platelet aggregation. To investigate the protective effect of CoQ10, we incubated the isolated blood cells with 50 μg/ml of TiO2 NPs in the presence and absence of 25 μM of CoQ10 for 3 h. Hemolysis, oxidative stress, LDH leakage and ATPase enzyme activity were studied in erythrocytes; cytotoxic and DNA damaging potential of NPs were determined in lymphocytes, along with mitochADP/ATP ratio were restored towards normal levels. TiO2 NPs induce cytotoxicity, damage DNA in lymphocytes, and induce oxidative/anti-oxidative imbalance in erythrocytes. Antioxidant CoQ10 protects erythrocytes and lymphocytes from toxicity induced by TiO2 NPs.Polymicrobial biofilm leads to wound healing delay. We set up an in vitro co-culture model of single- and triple-species biofilms of Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus faecalis with dermal fibroblast to assess the fibroblast response against to the different biofilms. Scratch and viability assays and biofilm cell quantifications were performed by WST-1, CLSM and plating method, respectively. Quorum sensing-related gene expression levels in P. aeruginosa and E. faecalis were analysed by reverse-transcriptase PCR. The immune responses of cells against S. aureus, P. aeruginosa and E. faecalis biofilms were measured by cytokine and matrix metalloproteinase analyzes. The influence of biofilm soluble factors on fibroblasts was also determined. After 24 h, triple-species biofilm cells caused the removal of the fibroblasts from the surfaces indicating the negative synergistic effect of three species. After co-cultures, twenty-five cytokines were significantly increased in fibroblast cells compared to control. Compared to other strains, the most important cytokine, chemokine and growth factors increased was observed in P. aeruginosa co-cultures with fibroblast. selleck compound While the expressions of fsrB and gelE genes were significantly upregulated in E. faecalis biofilm cells cultured with fibroblast cells, no significant difference was observed in P. aeruginosa. The wound healing and cell growth of fibroblasts were disrupted more aggressively in the presence of P. aeruginosa and triple-species biofilm cells. P. aeruginosa generally induced a stronger immune response in the fibroblasts than E. faecalis and S. aureus.We developed a novel method for the synthesis of bis-naphthoquinones (BNQ), which are hybrids of lawsone (2-hydroxy-1,4-naphthoquinone) and 3-hydroxy-juglone (3,5-dihydroxy-1,4-naphthoquinone). The anticancer activity of three synthesized compounds, named 4 (RC10), 5 (RCDFC), and 6 (RCDOH) was evaluated in vitro against two metastatic prostate cancer (PCa) cell lines, DU145 and PC3, using MTT assays. We found that 4 (RC10) and 5 (RCDFC) induced cytotoxicity against DU145 and PC3 cells. Flow cytometry analysis revealed that these two compounds promoted cell cycle arrest in G1/S and G2/M phases, increased Sub-G1 peak and induced inhibition in cell viability. We also showed that these effects are cell-type context dependent and more selective for these tested PCa cells than for HUVEC non-tumor cells. The two BNQ compounds 4 (RC10) and 5 (RCDFC) displayed promising anticancer activity against the two tested metastatic PCa cell lines, DU145 and PC3. Their effects are mainly associated with inhibition of cell viability, possibly through apoptotic cell death, besides altering the SubG1, G1/S and G2/M phases of cell cycle. 5 (RCDFC) compound was found to be more selective than 4 (RC10), when comparing their cytotoxic effects in relation to HUVEC non-tumoral cells. Future work should also test these compounds in combination with other chemotherapeutic drugs to evaluate their effects on further sensitizing drug-resistant metastatic PCa cells.The Chicago Classification (CC) is a dynamic, evolving classification scheme created by a diverse group of international esophageal experts. Its application has transformed the way esophageal motor data are used to define motility disorders, each iteration seeking to advance, simplify, and standardize the way clinicians worldwide diagnose esophageal dysmotility. The most recent update, CC version 4.0 (CCv4.0), emphasizes the importance of clinical context and distinguishes clinically relevant, conclusive manometric diagnoses from irrelevant manometric observations. Future iterations of CC may refine the classification of spastic esophageal disorders and incorporate machine learning and physics-based modeling to improve metrics.
