Abstract
Environmental exposure to pollutants, especially polycyclic aromatic hydrocarbons (PAHs), could lead to carcinogenesis development. However, there is a gap on the mechanisms involved in this effect. Therefore, the aim of this study was to investigate the potential relationship between exposure to environmental air pollution and inflammation process in DNA damage in taxi drivers. This study included 45 taxi drivers and 40 controls; non-smokers composed both groups. Biological monitoring was performed through quantification of urinary 1-hydroxypyrene (1-OHP). ICAM-1 (CD54) expression, NTPDase activity, inflammatory cytokine (IL-1β, IL-6, IL-10, TNF-α and IFN-γ) levels, and comet and micronucleus assays were evaluated. The results demonstrated that 1-OHP levels, ICAM-1 expression, NTPDase activity, and DNA damage biomarkers (% tail DNA and micronucleus frequency) were increased in taxi drivers compared to the control group (p < 0.01). Moreover, significant associations were found between 1-OHP levels and ICAM-1 expression, % tail DNA, and micronucleus frequency (p < 0.05). Besides, pro-inflammatory cytokine levels were positively correlated to % tail DNA and micronucleus frequency (p < 0.001). Our findings suggest an important association between environmental exposure to air pollution with increase of ICAM-1 expression and NTPDase activity in taxi drivers. Additionally, the multiple regression linear-analysis demonstrated association between IL-6 and DNA damage. Thus, the present study has provided important evidence that, in addition to environmental exposure to air pollutants, the inflammation process may contribute to DNA damage.

Abstract
Nanotoxicology aims to study the safety of nanomaterials, especially towards human exposure. Biodegradable polymeric nanocapsules have been indicated as potential drug carriers applicable for treating several pathologies. Thus, the objective of this study was to evaluate the potential cardiotoxicity of biodegradable lipid-core nanocapsules (LNC) containing poly(ε-caprolactone). Nanocapsules were characterized and the acute toxicity evaluation was conducted in Wistar rats. Two control groups (saline and tween/glycerol) were utilized, and three treated groups were chosen for low, intermediate and high doses: 28.7 × 1012 (LNC-1), 57.5 × 1012 (LNC-2) and 115 × 1012 (LNC-3), expressed as number of nanocapsules per milliliter per kg. Blood pressure measurements were performed in non-anesthetized animals by caudal plethysmography. The electrocardiographic (ECG) and echocardiographic analyses were carried out after anesthesia by isoflurane at two points, prior to treatment and after 14 days. Blood was collected 24 hours and 14 days after treatment. Biochemical and histopathological analyses were performed. During the evaluation period, no deaths, weight loss or clinical signs were observed. Post-treatment systolic pressures (24 h and 14 days) were significantly increased in comparison to pre-treatment in both control groups and treated groups, which is suggested to be as a possible consequence of the infused volume. Serum sodium, potassium, aspartate aminotransferase and alkaline phosphatase, as well as, hematological parameters were within reference values established for rats. ECG showed no indications of cardiotoxicity. Despite the echocardiograms, no alterations in the ejection fraction were found as indicators of cardiotoxicity. Cardiac histopathology also demonstrated no alterations. Therefore, the present results on acute evaluation after i.v. administration, by slow infusion, showed potential safety since no cardiotoxic effects by ECG, echocardiographic, arterial pressure, biochemical and histopathological analyses were found.

Protective effects of melatonin-loaded lipid-core nanocapsules on paraquat-induced cytotoxicity and genotoxicity in a pulmonary cell line. Mutat Res Genet Toxicol Environ Mutagen 2015; 784-785:1-9.

Abstract
Many acute poisonings lack effective and specific antidotes. Due to both intentional and accidental exposures, paraquat (PQ) causes thousands of deaths annually, especially by pulmonary fibrosis. Melatonin (Mel), when incorporated into lipid-core nanocapsules (Mel-LNC), has enhanced antioxidant properties. The effects of such a formulation have not yet been studied with respect to mitigation of PQ- induced cytotoxicity and DNA damage. Here, we have tested whether Mel-LNC can ameliorate PQ-induced toxicity in the A549 alveolar epithelial cell line. Physicochemical characterization of the formulations was performed. Cellular uptake was measured using nanocapsules marked with rhodamine B. Cell viability was determined by the MTT assay and DNA damage was assessed by the comet assay. The enzyme-modified comet assay with endonuclease III (Endo III) and formamidopyrimidine glycosylase (FPG) were used to investigate oxidative DNA damage. Incubation with culture medium for 24h did not alter the granulometric profile of Mel-LNC formulations. Following treatment (3 and 24h), red fluorescence was detected around the cell nucleus, indicating internalization of the formulation. Melatonin solution (Mel), Mel-LNC, and LNC did not have significant effects on cell viability or DNA damage. Pre-treatment with Mel-LNC enhanced cell viability and showed a remarkable reduction in % DNA in tail compared to the PQ group; this was not observed in cells pre-treated with Mel. PQ induces oxidative DNA damage detected with the enzyme-modified comet assay. Mel-LNC reduced this damage more effectively than did Mel. In summary, Mel-LNC is better than Mel at protecting A549 cells from the cytotoxic and genotoxic effects of PQ.

Abstract
Consistent evidence has indicated that the exposure to environmental air pollution increases the risk of cardiovascular disease. This study aimed to evaluate the possible effects of occupational exposure to air pollution, especially to polycyclic aromatic hydrocarbons (PAHs), and the influence of co-morbidities on the atherosclerotic process and inflammation. For that, biomarkers of exposure such as 1-hydroxypyrene urinary, oxidative damage and markers of cardiovascular risk were determined in plasma, serum and blood. In addition, inflammation models such as carotid intima-media thickness and serum inflammatory cytokines were analyzed in 58 taxi drivers with and without co-morbidity. The results demonstrated that considering only taxi drivers without co-morbidities, 15% presented carotid intima-media thickness above reference values. For the first time it has been demonstrated that urinary 1-hydroxypyrene levels were associated with carotid intima-media thickness and with serum homocysteine levels. The multiple linear regression analysis showed that several factors may contribute to the increased carotid intima-media thickness, among which age, interleukin-6, fibrinogen and exposure to PAHs stand out. In summary, our results suggest that chronic occupational exposure to atmospheric pollution could be an additional contributor to the atherogenesis process, leading to impaired vascular health. Moreover, carotid intima-media thickness, serum homocysteine levels, fibrinogen and the total cholesterol/HDL-c ratio could be suggested as preventive measures to monitor drivers' health.

Abstract
Mucopolysaccharidosis IVA is a lysosomal storage disorder leading to an increase in glycosaminoglycans storage. Genistein is an isoflavone capable to inhibit glycosaminoglycans production. The objective of this study was to analyze the in vitro effect of different concentrations of genistein on DNA injury in mucopolysaccharidosis IVA patients. The lower concentration tested (10 μM) showed a significant increase on DNA injury in vitro, although higher concentrations (30 μM and 50 μM) showed higher DNA damage.

Abstract
CONTEXT Alternanthera brasiliana (L.) Kuntze (Amarantaceae) is widely used in Brazilian traditional medicine as an analgesic, anti-inflammatory and antibacterial. OBJECTIVE To investigate the potential anti-inflammatory, analgesic, anxiolytic, and locomotor effect of the infusions in preclinical models. MATERIALS AND METHODS Anti-inflammatory activity was evaluated by a carrageenan-induced pleurisy test in Wistar rats (200 and 400 mg/kg, n = 6-7). Analgesic activity was evaluated by the number of abdominal contractions induced by 0.6% acetic acid administered to Swiss mice (25, 50, 100, 200, and 400 mg/kg, n = 10). Effects on the central nervous system (CNS) were evaluated in Wistar rats (100, 200, and 400 mg/kg, n = 10) using open field and plus maze models. RESULTS AND DISCUSSION Possible anti-inflammatory activity was indicated by the significant reduction of 19.8% for 200 mg/kg (p < 0.05) and 23.9% for 400 mg/kg (p < 0.05) of polymorphonuclear cells in pleural exudate. Analgesic activity was suggested by the significant reduction (p < 0.01) of number of abdominal contractions for all doses under study. No anxiolytic effect was noted, but there was an increase in the number of rearings in the group of rats treated with 100 mg/kg dose (p < 0.05). CONCLUSIONS Our findings suggest that the aqueous extract of the leaves of A. brasiliana has a potential pharmacological effect on inflammation and pain.
