Capacitor oil samples (PCBs > 90%wt) were treated in a bench scale experiment to investigate the destruction of PCBs during chemical destruction processes (a catalytic hydrodechlorination treatment with palladium carbon and additional treatment with potassium tert-butyloxide). Using those results, this study confirmed the decrease of PCBs and other undesirable dioxin-like compounds such as PCDD/Fs in treated samples during the treatment. Dioxin-responsive chemical-activated luciferase expression (DR CALUX®) AhR reporter gene bioassay was used to evaluate dioxin-like activity in the samples. During the treatment, the efficiency for PCB capacitor oil was around 99.99% or more in WHO-TEQ and CALUX-TEQ, whereas the sum of PCBs was reduced at a resulting efficiency of >99.9999%. In this study, a new cleanup procedure for separating PCBs from the mineral oil matrix was also developed for DR CALUX. The procedure consists of dimethylsulphoxide partitioning followed by silica gel-44% sulphuric acid reflux treatment and activated carbon chromatography. With the cleanup, CALUX-TEQ values were in good agreement with WHO-TEQ values and were as much as 3.3 times higher than WHO-TEQs for untreated/treated PCB-containing insulating oil samples. The DR CALUX results of mineral oil samples containing various PCB concentrations of 0.5–50 mg/kg (corresponding WHO-TEQs: 0.012–1.2 μg-TEQ/g) also correlated well with WHO-TEQs (CALUX-TEQ/WHO-TEQ ratio =1.0–3.0), which was consistent with the theoretical quantification limit of the CALUX. These results supported the validity of the proposed clean-up method.

ABSTRACT Fish consumption is the principal source of intake of organochlorinated compounds in humans. Compared with other types of foods of animal origin, fish contain the highest levels of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzofurans, all of which are classified as highly toxic organochlorine compounds. Currently, lakes and fish farms in northern Italy are not regularly monitored for PCBs and dioxins in areas contaminated by industrial sources, partially because of the high costs of traditional analytical methods that limit the number of samples to be analyzed. The DR-CALUX cell bioassay is based on the uptake of the cellular aryl hydrocarbon receptor (AhR) for dioxins and dioxin-like compounds. The aim of this study was to assess the levels of dioxins and dioxin-like PCB contamination in Lake Maggiore and Lake Como, two lakes in northwestern Italy, and in nearby areas. The levels were quantified using the cell bioassay DR-CALUX and reference controls in two wild fish species, perch (Perca fluviatilis) and roach (Rutilus rutilus), and in a farmed species, rainbow trout (Oncorhynchus mykiss). Tissue samples collected from the farmed rainbow trout were also submitted to immunohistochemical analysis of CYP1A expression as a marker for environmental pollutant-induced liver damage. The levels of dioxins, furans, and dioxin-like PCBs were all below the maximum levels and action limits set by European Union Regulation, suggesting no risk for human health associated with the consumption of the fish species caught or farmed in these areas.

A retrospective analysis to explore the applicability of fish biomarkers and sediment bioassays along contaminated salinity transects. – ICES Journal of Marine Science, 66: 2089–2105. Biological-effects monitoring in estuarine environments is complex as a result of strong gradients and fluctuations in salinity and other environmental conditions, which may influence contaminant bioavailability and the physiology and metabolism of the organisms. To select the most robust and reliable biological-effect methods for monitoring and assessment programmes, a large-scale field study was conducted in two estuarine transects in the Netherlands. The locations ranged from heavily polluted harbour areas (the ports of Rotterdam and Amsterdam) to cleaner coastal and freshwater sites. Assessment methods used included a variety of biomarkers in flounder (Platichthys flesus) and a range of in vitro (sediment extracts) and in vivo bioassays. Multivariate statistical analysis was applied to investigate correlations and relationships between various biological effects and contaminant levels in flounder liver or sediments. Several biological methods seemed to be too much affected by salinity differences for routine use in estuaries. The most discriminative biomarkers in the study were hepatic metallothionein content and biliary 1-OH pyrene in fish. Mechanism-based in vitro assays DR-CALUX and ER-CALUX applied to sediment extracts for screening of potential toxicity were much more responsive than in vivo bioassays with macro-invertebrates using survival as an endpoint.

A topsoil sample obtained from a highly industrialized area (Taranto, Italy) was tested on the DR-CALUX® cell line and the exposed cells processed with proteomic and bioinformatics analyses. The presence of polyhalogenated compounds in the topsoil extracts was confirmed by GC-MS/MS analysis. Proteomic analysis of the cells exposed to the topsoil extracts identified 43 differential proteins. Enrichment analysis highlighted biological processes, such as the cellular response to a chemical stimulus, stress, and inorganic substances; regulation of translation; regulation of apoptotic process; and the response to organonitrogen compounds in light of particular drugs and compounds, extrapolated by bioinformatics all linked to the identified protein modifications. Our results confirm and reflect the complex epidemiological situation occurring among Taranto inhabitants and underline the need to further investigate the presence and sources of inferred chemicals in soils. The combination of bioassays and proteomics reveals a more complex scenario of chemicals able to affect cellular pathways and leading to toxicities rather than those identified by only bioassays and related chemical analysis. This combined approach turns out to be a promising tool for soil risk assessment and deserves further investigation and developments for soil monitoring and risk assessment.

To study somatostatin/dopamine (SS/D) synergy in a human cell system constitutively expressing SS and D receptors (SSR and DR, respectively), we characterized the expression of SSR and DR subtypes in the non-small-cell lung cancer line Calu-6, and then we evaluated the effect on cell proliferation of SS/D chimeric molecules (BIM-23A387 and BIM-23A370), which bind with high affinity both sst2 and D2R, and compared the results with those obtained by using SS-14 and subtype-selective SS analogs (SSA) and D agonists (DA). Because Calu-6 cells produce insulin-like growth factor (IGF) and IGF-binding protein (IGFBP) peptides, which play a role in the autocrine/paracrine control of cell growth, we also investigated the effects of chimeric compounds on secretion and expression of IGF system components. Relative high levels of sst2 and the long isoform of the D2R were detected by real-time RT-PCR and Western blot in Calu-6, together with sst5 and to a lesser extent sst3 and D4R. BIM-23A387 and BIM-23A370 significantly inhibited growth of Calu-6, whereas IGF-IGFBP secretion or expression was unaffected, suggesting a direct inhibitory effect. The inhibition of cell growth, measured by both [3H]thymidine incorporation and cell count, was significantly lower when individual SSA and DA control peptides or subtype-specific SSA and DA were tested. BIM-23A370 was more potent than BIM-23A387 ( P < 0.001). These findings show that SS/D chimeras can inhibit Calu-6 proliferation in an IGF-independent manner and suggest that this enhanced potency might be because of the induction of SSR/DR dimerization. The Calu-6 cell line, constitutively expressing SSR and DR, provides a suitable model to elucidate the mechanism of action of SSA and DA on regulation of cell growth and to characterize the interaction between SSR and DR.

Abstract Introduction Air pollution, water and soil pollution produce impaired quality of life and expose the population to contaminants that can cause cancer. One of the main pollutants are DLC, a group of highly toxic chemicals that enter the body in about 90% through our food, and are classified as type I carcinogens by the International Agency for Research on Cancer. In the U.S. and Europe during the twentieth century there was an increase in the incidence of NHL that has stabilized in recent years which is coincident with the implementation of strong dioxin emission regulations. In Chile there has been a higher incidence of NHL in recent decades so we decided to evaluate DLC levels in patients with NHL and compared them with a normal control population. Patients and Methods In order to achieve this goal a descriptive observational, case-control unpaired, epidemiological study was designed. Patients with NHL diagnosed in the Hospital of Valdivia in 2011 and 2012 were considered in the study. The control group was composed by individuals without cancer, from the same geographical area as the patients. All volunteers were asked if they wished to participate in the study using an informed consent. Blood sample without anticoagulant was obtained from each individual. Serum was aliquoted and stored at -20 ° C for later quantification of total lipids and DLC with sulfo-phospho-vanillin assay colorimetric method and DR-CALUX ® Bioassay, respectively (screening method approved by FDA and EEC). A nonparametric statistical hypothesis was constructed using Wilcoxon rank sum test to compare two independent samples considering a non-symmetrical distribution of the variable DLC (pg TEQ / total lipids) and a significance level of α= 5%. Results 51 patients with NHL and 100 controls entered the study. The mean ages of the LNH group and the control group were 59±14.5 and 39± 16.9 years, respectively. The male/female ratio was 0.52 and 0.82 in the LNH and control group, respectively. NHL cases were from southern regions of Chile matching that of controls in a 100%. The histopathology of NHL cases was in 90% of B lineage. The concentration of DLC was quantified in all cases and expressed in toxicity equivalents (TEQ) using as reference the 2,3,7,8, tetracloroparadibenzodioxine and corrected to the value of total serum lipids (pg TEQ / total lipids). In all samples analyzed DLC were detected. The DLC levels found for NHL cases and controls were 28.33 ± 28.57 and 15.02 ± 7.64 pg TEQ / total lipids, respectively. The median values for cases and controls were 19.02 and 12.67 pg TEQ / total lipids, respectively. The analysis with Wilcoxon rank sum test showed a statistically significant evidence (z = -4.44, p = 0.0000) (Figure 1). Conclusions The cases and controls analyzed came from a geographical area of 1200 km of extension without polluting industries having detectable levels of DLC in all them. DLC levels NHL cases were higher compared with controls. When comparing the results of the controls (15.02 pg TEQ / g lipid) with other studies in unexposed populations we find similar levels in Northern Australia and Taiwan, 10.9 and 15.2 pg TEQ / g lipid, respectively (Harden et al. 2007 and Chen et al., 2005). Levels are higher in areas with higher industrial activity as France, Slovakia and Belgium (Marchand et al. 2004 Chovancová et al 2012, Bilau et al., 2009), and lower for residents of Fukuoka and Athens (Masuda et al. , 2005 Costopoulou et al., 2006). The vast region from which the controls come from in our study, with an environment relatively free of pollution leads us to infer that DLC are basically food contaminants, since the majority of the population consume food products manufactured in areas of high industrial activity and distributed throughout the country. DLC studies in populations exposed to higher pollution (Viel et al., 2008) have shown increased incidence of NHL in those areas. This makes us pose the hypothesis of a potential pathogenic role of DLC in NHL that could be mediated by genetic mechanisms and / or deregulated B cell expansion.

Objective: To present our ‘methylene blue-guided retroperitoneoscopy technique’ that we apply in cases where extravasation develops for various reasons and is complicated as a result in Percutaneous Nephrolithotomy surgery (PNL). Material and Methods: A total of 36 patients, who underwent PNL with the ‘methylene blue technique’ at Bakirkoy Dr. Sadi Konuk Training and Research Hospital between 2014 and 2020, were retrospectively evaluated. The study included only cases in which the ‘methylene blue-guided retroperitoneoscopy technique’ was used due to the inability to advance the Amplatz sheath to the targeted calyx due to renal scarring or a staghorn stone filling the targeted calyx, Amplatz sheath was withdrawn from the kidney with the guidewire due to the inattention of the assistant surgical team or contrast material extravasation. The patients’ demographic, preoperative, perioperative, and postoperative data were recorded, and stone-free and complication rates were noted. Results: The mean age of the patients was 45.1 (36-55) years, the mean body mass index was 27.8±4 kg/m2, the mean stone size was 3.4±0.7 cm, and the mean stone volume was 22.3±10.2 cm3. The mean operation time was calculated as 95.8±30.3 minutes. The stone-free rate was 68% on the postoperative first day and 75% on the third month. Eight patients (22.2%) underwent a secondary procedure (extracorporeal shock wave lithotripsy or flexible ureterorenoscopy). Conclusion: The ‘methylene blue-guided retroperitoneoscopy technique’ we apply under retroperitoneoscopic direct vision is a safe and practical option for re-accessing the kidney by locating the calyx, which is first partially or completely dilated. Keywords: methylene blue, retroperitoneoscopy, renal access failure, percutaneous nephrolithotomy

Diabetic retinopathy (DR) is a neurovascular disease characterized by the reduction of retina integrity and functionality, as a consequence of retinal pigment epithelial cell fibrosis. Although galectin-1 (a glycan-binding protein) has been associated with dysregulated retinal angiogenesis, no evidence has been reported about galectin-1 roles in DR-induced fibrosis. ARPE-19 cells were cultured in normal (5 mM) or high glucose (35 mM) for 3 days, then exposed to the selective galectin-1 inhibitor OTX008 (2.5–5–10 μM) for 6 days. The determination of cell viability and ROS content along with the analysis of specific proteins (by immunocytochemistry, Western blotting, and ELISA) or mRNAs (by real time-PCR) were performed. OTX008 5 μM and 10 μM improved cell viability and markedly reduced galectin-1 protein expression in cells exposed to high glucose. This was paralleled by a down-regulation of the TGF-β/, NF-kB p65 levels, and ROS content. Moreover, epithelial–mesenchymal transition markers were reduced by OTX008 5 μM and 10 μM. The inhibition of galectin-1 by OTX008 in DR may preserve retinal pigment epithelial cell integrity and functionality by reducing their pro-fibrotic phenotype and epithelial–mesenchymal transition phenomenon induced by diabetes.

Abstract Excretion of toxicants accumulated from firefighter exposures through breastmilk represents a potential hazard. We investigated if firefighting exposures could increase the concentration of polybrominated diphenyl ethers (PBDEs) and aryl hydrocarbon receptor (AhR) activation in excreted breastmilk. Firefighters and non-firefighters collected breastmilk samples prior to any firefighting responses (baseline) and at 2, 8, 24, 48, and 72 hours after a structural fire (firefighters only). Five PBDE analytes (BDEs 15, 28, 47, 99, and 153) detected in at least 90% of samples were summed for analyses. The AhR in vitro DR CALUX® bioassay assessed the mixture of dioxin-like compounds and toxicity from breastmilk extracts. Baseline PBDEs and AhR response were compared between firefighters and non-firefighters. Separate linear mixed models assessed changes in sum of PBDEs and AhR response among firefighters over time and effect modification by interior or exterior response was assessed. Baseline PBDE concentrations and AhR responses did not differ between the 21 firefighters and 10 non-firefighters. There were no significant changes in sum of PBDEs or AhR response among firefighters over time post-fire, and no variation by interior or exterior response. Plots of sum of PBDEs and AhR response over time demonstrated individual variation but no consistent pattern. Currently, our novel study results do not support forgoing breastfeeding after a fire exposure. However, given study limitations and the potential hazard of accumulated toxicants from firefighter exposures excreted via breastfeeding, future studies should consider additional contaminants and measures of toxicity by which firefighting may impact maternal and child health.

We take this opportunity of correcting proofing errors in Kenneth Campbell's review of Szymanowski in seiner Zeit which were not properly rectified as the issue went to press. Page 35, paragraph 2, line 1: for ‘of read ‘on’. Line 5, for ‘Witkicwcz’ read ‘Witkiewicz’, and line 15, for ‘Bonski’ read ‘Blonski’. On p.36, para 2, the square brackets should not appear around the quotation but around the names ‘Scriabin’ and ‘Szymanowski’. Four lines after the quotation, insert ‘clever’ before ‘pastiche’. We extend our apologies to Dr. Campbell.With regard to Calum MacDonald's record review on pp.47–49, it has been pointed out that the Irish Free State was formed in 1922, not 1920; but the latter date is the one given on the record-sleeve, as Mr. MacDonald reported. He wishes, however, to correct two proofing errors and one oversight in the review; p.48, for ‘Hcfferman’ read ‘Heffernan’ and p.49, for ‘Eirann’ read ‘Eireann’. On both pages, for ‘Cathlccn ni Hovighlighan’ read ‘Caitilin ni Uallachain’ throughout.

Abstract This study focusses on the adsorption efficiency of cotton pod (Gossypium arboreum) for biosorption of direct red (DR) 80 dye. The effect of dye concentration, pH, shaking time, adsorbent dose and temperature was considered to evaluate the adsorption efficiency of the cheapest raw material on the removal of dye. Various concentrations (10–50 ppm) were examined and maximum percentage removal of the adsorbent was obtained at pH 1 with adsorbent dose of 0.9 g and shaking time of 60 min. To enhance the adsorption efficiency of the adsorbent, the cotton calyx was treated with FeSO4.7H2O and investigated the removal of the raw adsorbent and the composite. It was examined that the removal efficiency of the composite is more than that of raw adsorbent. The composite was more efficient as dye removal reached up to 97%. FTIR of the composite shows an additional peak at 650 cm−1 for presence of Fe-O group and confirmation of composite formation. SEM micrograph showed that the particles in composite are more packed compared to the raw adsorbent. Mathematical models were applied and kinetic studies also have been done to provide better results regarding to the experimental data. It is concluded that the prepared adsorbent could be used as a tool for the removal of toxic pollutants from textile wastewater.

Abstract. Dechavez R, Calub ML, Genobata DR, Balacuit R, Jose R, Tabugo SR. 2022. Identification of culture-dependent microbes from mangroves reveals dominance of Bacillus including medically important species based on DNA signature. Biodiversitas 23: 5342-5350. Mangroves are among the most crucial plant hosts in the marine environment because of their notable role in the ecosystem and their benefits. Identification of plant-associated and culture-dependent microbes is key to having a rich reservoir of bioactive substances. DNA barcoding was done based on 16S rRNA gene and ITS region. In this study, seven (7) mangrove species were identified as hosts. Results show that most bacterial isolates from plant leaves were gram-positive bacteria belonging to phylum: Firmicutes and genus Bacillus. Phylogenetic inference reveals a diverse non-monophyletic group with medically and economically necessary species. Among the host plants, Sonneratia alba harbored the most species of bacteria and fungi. These include two medically important strains of B. cereus and B. thuringiensis and host-specific bacteria like B. altitudinis in S. alba, B. velezensis in Rhizophora apiculata, B. clausii in Avicennia marina and B. firmus in A. marina were revealed. Meanwhile, some bacteria like B. subtilis and B. megaterium were found in three host species and B. cereus was the most abundant being recorded in four host plants. Diverse strains of fungi, Aspergillus sp., A. nomiae, A. tubingensis and A. niger were also present. This study served as baseline data for future research on diversity and host ecology for possible drug discovery.
