Abstract
AIM The current study aimed at analyzing the effect of non-surgical periodontal treatment accompanied by systemic antibiotics on salivary enzyme activities, periodontal parameters, and glycemic control in type-2 diabetic (T2D) patients with chronic periodontitis. METHODS The study included 125 type-2 diabetic patients with chronic periodontitis who had good glycemic control (T2Dc), 125 type-2 diabetics who had bad glycemic control (T2Dpc). The 125 T2Dpc were divided randomly into two groups. The first one enrolled 63 T2Dpc and received a non-surgical periodontal treatment (T2Dpc + NST). The second group enrolled 62 T2Dpc and received the non-surgical treatment accompanied by systemic antibiotics (T2Dpc+NST+A). HbA1c, periodontal indices, and salivary enzyme activities were assessed for all groups. The Glycated hemoglobin (HbA1c) was assessed. The Salivary alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransaminase (ALT), lactate dehydrogenase (LDH), and creatine kinase (CK) activities were measured. RESULTS The T2Dpc were characterized by the highest probing depth (PPD) and clinical attachment loss (CAL) periodontal scores, as well as ALP, AST, and ALT enzymatic activities. However, BOP did not differ significantly between T2Dc and T2Dpc. Whereas the rest of clinical parameters PI, GI, and OHI-S did not significantly differ between groups. The Pearson's analysis revealed three correlations between ALP-PPD, ALP-CAL, and ALP-BOP (bleeding on probing) in both T2Dc and T2Dpc (P < 0.05). Interestingly, a significant decrease in periodontal indices, salivary enzyme activities, and HbA1c was recorded in T2Dpc+NST+A group. CONCLUSION The increase in ALP, AST, and ALT activities reflects the impact of uncontrolled T2D on periodontal tissue alteration. The ALP activity increase was associated with the severity of periodontal status in diabetic patients. In comparison to non-surgical treatment alone, the adjunct use of systemic antibiotics improves periodontal state, enzyme activity, and glycemic control.

Abstract
BACKGROUND Vitiligo is a common chronic hypomelanotic skin disorder. An intricate pool of markers associated with a complex combination of biological and environmental factors is thought to be implicated in etiology. This study aims to investigate the most important markers associated with vitiligo pathogenesis, including redox status, inflammation, and immune profile, in patients with vitiligo. MATERIALS AND METHODS The study included a total of 96 subjects: 30 patients with active non-segmental vitiligo, 30 patients with stable non-segmental vitiligo, and 36 controls. The vitiligo area severity index (VASI) and vitiligo disease activity score (VIDA) were determined. The following serum parameters were assessed: antioxidant status (TAS), superoxide dismutase activity (SOD), catalase activity (CAT), glutathione peroxidase activity (GPx), glutathione-S-transferase activity (GST), malondialdehyde (MDA), advanced oxidation protein products (AOPP), C reactive protein (CRP), interleukin-15 (IL-15), and chemokines (CXCL9, CXCL10). RESULTS The VASI score was not significantly different between active and stable vitiligo patients, as it was approximately 0.1. TAS, CAT, GPx, and GST were significantly lower in vitiligo patients compared to controls (p < 0.05). They were also significantly lower in active vitiligo when compared to stable vitiligo (p < 0.05). However, SOD levels were significantly higher in vitiligo patients than in controls and in the active vitiligo group than in the stable vitiligo group (p < 0.05). MDA and AOPP levels were significantly higher in patients with active and stable vitiligo compared to controls (p < 0.05). However, they did not significantly differ between active and stable vitiligo patients (p < 0.05). In both active and stable vitiligo, CRP and IL-15 were significantly higher than controls (p < 0.05). Whereas CRP was significantly higher in active (range = 2.0-7.2, mean = 4.46 ± 1.09) than in stable vitiligo (range = 1.6-6.7, mean = 3.75 ± 1.08) (p < 0.05). There was no significant difference in IL-15 levels between active and stable vitiligo. In both active and stable vitiligo, CXCL9 and CXCL10 were significantly higher than controls (p < 0.05), and they were significantly higher in active than stable vitiligo (p < 0.05). CONCLUSIONS In vitiligo, oxidative damage induces an increase in pro-inflammatory IL-15, which in turn promotes IFN-γ-inducible chemokines such as CXCL9 and CXCL10. Further, there seems to be a link between the VASI score and IL-15 levels. These data imply that inhibiting IL-15 could be a promising method for developing a potentially targeted treatment that suppresses the early interplay between oxidant stress and IL-15 keratinocyte production, as well as between resident and recirculating memory T cells.

Abstract
BACKGROUND/PURPOSE Studies have shown that there is a possible correlation between the amount of glycated hemoglobin and the periodontal status. The goal of this study was to investigate the relationship between glycated hemoglobin (HbA1c) and the prevalence of gingival pathogens and circulating interleukin levels in type II diabetic Tunisian subjects. MATERIAL AND METHODS The research included four groups; 30 healthy subjects (H group), 30 non-diabetic subjects suffering from chronic periodontitis (CP group). Type-II diabetic patients were divided according to HbA1c level into 30 adequately-controlled type-II diabetes subjects (HbA1c ≤ 7 percent (ATIID&CP group)) and 30 inadequately-controlled type-II diabetes subjects and HbA1c > 7 percent (ITIID&CP group). Clinical periodontal condition parameters and assessment of salivary interleukin IL-1beta, IL-6 and IL-10 were assessed. Quantitative Polymerase Chain Reaction used for detection of Subgingival biofilm of periodontal pathogens. RESULTS Clinical parameters analyzed were positively associated with HbA1c levels (p < 0.05). A. Actinomycetemcomitans were found in 80 percent of ITIID&CP, 65 percent of CP and almost absent in H group. Porphyromonas gingivalis was present in 100 percent of CP, 85 percent of ITIID&CP, 50 percent of ATIID&CP and 3 percent of H group. T. Denticola had an equivalent occurrence. While Tannerella forsythia was scarce in ITIID&CP groups, but abundant in the H group. ITIID&CP had the highest IL-6 and IL-1beta/IL-10 ratios. CONCLUSION HBA1c levels affect periodontal status, pathogens and salivary interleukins in Type-II diabetic Tunisians with chronic periodontitis, compared with stable and chronic periodontitis groups and can interact with periodontal infections and increase the inflammatory state.

Abstract
Objectives Hypercementosis (HC) is an asymptomatic excessive cementum deposition at the dental root apex. There is a lack of research that determines the pattern and associated factors of HC in Saudi Arabia. Materıals and Methods A retrospective cross-sectional study was conducted on a random sample of 815 Orthopantomograms (OPGs) that was obtained from a total of 14003 female patients archived OPGs. The OPGs were retrieved from the Kodak Carestream-R4 database for the period between 2015 and 2017 at Taibah University Dental College and Hospital (TUDCH), Al-Madinah Al-Munawwarah, Saudi Arabia. Width and radiodensity of HC were measured and the distribution was calculated. Association between HC and factors including age and nationality were explored. Descriptive and inferential analyses were performed. Results The mean/SD age of HC affected patients (9.8%) was 30.16 ± 13.1 years, of whom 55% were Saudis. The mean/SD width and radiodensity of the hypercementosed roots were 4.14 ± 1.2 mm and 119.86 ± 29.83, respectively. The mandibular teeth were more frequently associated with hypercementosis (65%) specifically first molars (47.5%), while the majority (64%) had a single unilateral distribution pattern. There was a non-significant association between nationality, age, and HC (P = 0.921, P = 0.633, respectively). Conclusion Hypercementosis observed in 9.8% of female patients attending TUDCH which was primarily unilateral and prominently confined to the mandibular teeth roots. The complication of teeth extraction among female patients in Almadinah region should be anticipated.

Abstract
Studies on the toxicity of Mediterranean jellyfish have gained attention owing to their weak toxic properties. Our research has been mainly performed on the Scyphomedusae. Pelagia noctiluca is a scyphozoan jellyfish which causes a danger to sea bathers and fishery damages in the Mediterranean Sea. To check whether the cytotoxicity of Pelagia noctiluca nematocysts was associated to DNA lesions, we have looked for DNA fragmentation by means of the Comet and chromosome aberration assays. To specify cell death pathway, we have investigated caspase-3 activation. Our results have shown that nematocysts reduced cell viability and induced DNA fragmentation in a concentration-dependent manner with a maximum effect at 150 000 nematocysts mL(-1). The high percentage of chromosome aberrations also emphasized the genotoxic character of Pelagia noctiluca nematocysts in Vero cells. This fragmentation was correlated to apoptosis induction which was confirmed by caspase-3 activation. In conclusion, the present report has suggested that Pelagia noctiluca nematocysts were able to promote apoptosis in Vero cells and therefore may be useful in cancer therapy.

Abstract
Pelagia noctiluca, a jellyfish widely distributed in the Mediterranean waters, especially in coastal areas of Tunisia, has garnered attention because of its stinging capacity and the resulting public health hazard. Crude extracts of P. noctiluca nematocysts have been tested for their cytotoxicity on Vero cells. Our results clearly showed that nematocysts induced cell mortality in a dose- and time-dependent manner. A cytoprotective effect against cell mortality was obtained when Vero cells were treated with Vitamin E. This process was further confirmed by the generation of reactive oxygen species (ROS) and the induction of Hsp 70 and 27 protein expressions. Thus, our findings suggested that oxidative stress is involved in the toxicity of pelagia nematocysts and may therefore constitute the major mechanism of this medusa nematocysts toxicity.

Abstract
Patulin (PAT) is a mycotoxin produced in fruits, mainly in apples, by certain species of Penicillium, Aspergillus, and Byssochlamys. It has been shown that PAT is cytotoxic, genotoxic, and mutagenic in different cell types. Several studies incriminate the oxidative stress as a mechanism of PAT-mediated toxicity. In this context, our aim was to investigate the protective role of Vitamin E (Vit E), an antioxidant agent, against PAT induced cytotoxicity and genotoxicity in cultured HepG2 cells. The obtained results showed that addition of Vit E in cells treated with PAT significantly reduce cell mortality induced by this toxin. In the same conditions, Vit E decreased the intracellular level of ROS, reduced PAT induced p53 expression, and reversed PAT induced DNA damage. In addition, Vit E prevented significantly the percentage of chromosome aberrations induced by PAT in HepG2 cells in a concentration dependant manner. These results suggest that Vit E, an exogenous antioxidant agent, plays an important role in defense against PAT-induced cytotoxicity and genotoxicity, which confirms the involvement of oxidative stress in the induction of DNA damage by PAT in HepG2 cells.

Abstract
Epidemiological studies suggest that cytogenetic biomarkers, such as micronuclei (MN) in peripheral blood lymphocytes may predict cancer risk because they indicate genomic instability. The objective of the present study was to evaluate the frequencies of MN and chromosome aberrations (CA) in peripheral blood lymphocytes of hospital workers exposed to ionizing radiation and healthy subjects. The study was conducted using peripheral blood lymphocytes from 30 workers from the radiology department and 30 from the cardiology department. This study included 27 healthy age- and sex-matched individuals as the control group. The assessment of chromosomal damage was carried out by the use of CA and micronucleus assays in peripheral lymphocytes. Our results show that CA and micronucleus frequencies were significantly higher among the exposed groups when compared to controls. Our finding of significant increase of CA and MN frequencies in peripheral lymphocytes in exposed workers indicates a potential cytogenetic hazard due to this exposure. The enhanced chromosomal damage of subjects exposed to genotoxic agents emphasizes the need to develop safety programs.

Background The biodiversity of the marine environment and the associated chemical diversity constitute a practically unlimited source of new active substances in the field of the development of bioactive products. In our study, we have investigated the efficiency of the venom from the Mediterranean jellyfish, Pelagia noctiluca and its fractions for anti-proliferative and anti-cell adhesion to cell–extracellular matrix activities. Results Our experiments have indicated that the separation of the Mediterranean jellyfish Pelagia noctiluca crude venom extract by sephadex G-75 chromatography led to four fractions (F1, F2, F3, and F4). Among the four fractions F1 and F3 were cytotoxic against U87 cells with IC50 values of 125 and 179 μg/ml respectively. The venom, F1, F2 and F 3 showed significant anti-proliferative activity in time-dependent manner. Our results also suggest that these fractions and the venom are able to inhibit cell adhesion to fibrinogen in dose-dependent manner. This inhibition is reliant on its ability to interact with integrins. Conclusions To conclude, we have demonstrated for the first time that Pelagia noctiluca venom and its fractions especially (F1 and F2) display potent anti-tumoral properties. Separation by sephadex G-75 chromatography give rise to more active fractions than the crude venom extract. The purification and the determination of chemical structures of compounds of these active fractions are under investigation. Overall, Pelagia noctiluca venom may has the potential to serve as a template for future anticancer-drug development.

Abstract
Background Toxins derived from jellyfishes have been exploited as a model for the development of new drug promising applications to treat neurodegenerative diseases. The present work is aimed to evaluate the acute toxicity of crude venom of Pelagia noctiluca and then to screen the analgesic and antibutyrylcholinestrasic (anti-BuChE) activities of the crude venom and its fractions. Methods Sephadex G75 gel was used to separate crude venom of Pelagia noctiluca, which led to some fractions. In addition, in vivo analgesic and in vitro plasma antibutyrylcholinestrasic activities were carried out with Pelagia crude venom and its fractions respectively. Results The crude venom and its fractions displayed analgesic and anti-BuChE activities at different doses without inducing acute toxicity. Fraction 2 possesses the highest analgesic and antibutyrylcholinestrasic properties. The crude venom and fraction 1 had shown to possess less significant inhibitory activity against analgesic and antibutyrylcholinestrasic models. Conclusions Based on this study, the crude venom of Pelagia noctiluca is found to be a useful tool for probing pharmacological activity. The purification and the determination of chemical structures of compounds of active fractions of the venom are under investigation.

Abstract
BACKGROUND Removal of numerous classes of chemical pollutants from the industrial wastewater such as textile, pharmaceutical and olive mill using conventional wastewater treatment, is incomplete and several studies suggested that improvement of this situation would require the application of biological treatment techniques. Dyes, polyphenols and drugs are an environmental pollutants extremely toxics to plants and other living organisms including humans. These effluents were previously treated by Pseudomonas putida. The main of this work was to evaluate the in vivo toxicity of the three wastewaters. METHODS Writhes and convulsant effect of effluents were carried out and were compared to the treated effluents. Only pharmaceutical wastewater was exhibited a convulsant effect which observed in mice treated by effluent. On the other hand, all industrial wastewater induced significantly an algogenic effects particularly when mice were treated by the pharmaceutical wastewater (Number of writhes = 44). CONCLUSION Toxicity was totally removed when mice were treated by the bio remediated effluent. This indicates that P. putida was able to completely detoxify the toxic industrial effluent.

Abstract
Background The long-lasting and abundant blooming of Pelagia noctiluca in Tunisian coastal waters compromises both touristic and fishing activities and causes substantial economic losses. Determining their molecular mode of action is, important in order to limit or prevent the subsequent damages. Thus, the aim of the present study was to investigate the propensity of Pelagia noctiluca venom to cause oxidative damage in HCT 116 cells and its associated genotoxic effects. Results Our results indicated an overproduction of ROS, an induction of catalase activity and an increase of MDA generation. We looked for DNA fragmentation by means of the comet assay. Results indicated that venom of Pelagia noctiluca induced DNA fragmentation. SDS-PAGE analysis of Pelagia noctiluca venom revealed at least 15 protein bands of molecular weights ranging from 4 to 120 kDa. Conclusion Oxidative damage may be an initiating event and contributes, in part, to the mechanism of toxicity of Pelagia noctiluca venom.

Abstract
Zearalenone (ZEN) is a non-steroidal estrogenic mycotoxin produced by Fusarium fungi. It contaminates different components of the food chain and can cause serious economic and public health problems. The major metabolites of ZEN in various animal species are alpha- and beta-zearalenol (α-, β-ZOL). Some in vivo studies have shown that these two metabolites are as toxic as the mother molecule (ZEN), but other investigations have demonstrated that α- and β-ZOL are less toxic than ZEN. Thus, the aim of the present study was to evaluate cytotoxicity and genotoxicity of α- and β-ZOL in vivo, in mouse bone-marrow cells and in vitro, in cultured HeLa cells, and to compare it with ZEN. ZEN showed the same cytotoxicity as α-ZOL and both are more cytotoxic than β-ZOL. Genotoxicity of ZEN and its derivatives was assessed by the chromosome aberration assay. Our results show that ZEN as well as α- and β-ZOL increased the percentage of chromosome aberrations in mouse bone-marrow cells and in HeLa cells. In the two systems, ZEN and α-ZOL exhibited the same range of genotoxicity and both were more genotoxic than β-ZOL. Furthermore, our results show that either ZEN or its two metabolites inhibited cell viability in a dose-dependent manner. We conclude that biotransformation of ZEN may be considered as only a partial detoxification pathway since the resulting metabolites remain relatively toxic.

Abstract
Zearalenone (ZEN) is a potent estrogenic metabolite. Evidence of its cytotoxicity and genotoxicity has recently emerged from several reports. This study was conducted to evaluate the ability of cactus (Opuntia ficus-indica) cladodes to protect Balb/c mice against ZEN induced genotoxicity. To this end, the effect of a single dose of ZEN (40 mg/kg b.w.) alone and with extract of cactus cladodes (25, 50 and 100 mg/kg b.w.) was monitored by measuring: (i) micronuclei induction in bone marrow cells, (ii) chromosome aberrations mainly breaks and gaps in bone marrow cells also and finally and (iii) DNA fragmentation in liver and kidney. Our results clearly show that ZEN is genotoxic to Balb/c mice. It induces DNA damage as indicated by DNA fragmentation, micronuclei and chromosomal aberrations in bone marrow cells. It is of note that cactus cladodes extract assayed alone at high dose (100 mg/kg b.w.) was found completely safe and did not induce any genotoxic effects. The simultaneous administration of cactus cladodes extract with ZEN resulted in an efficient prevention of micronuclei (the number of PCE MN decreased from 71.3+/-6.1 for animals treated with Zen to 32.6+/-15.5 for animals treated with cactus cladodes), chromosomal aberrations frequency (the % of chromosomal aberrations decreased from 38.3+/-3.0 to 18.6+/-1.1) in bone marrow cells and of DNA fragmentation compared to the group treated with ZEN alone. It could be concluded that cactus cladodes extract was effective in the protection against ZEN genotoxicity. This could be relevant, particularly with the emergent demand for natural products which may neutralize the genotoxic effects of the multiple food contaminants.
