AB  - The aim of the study was to investigate the potency of Cinnamomum camphora cineoliferum and Melaleuca ericifolia essential oils (EOs) against facultative and obligate anaerobes isolated from teeth’ infected root canals. Biocompatibility of the EOs was also in the study focus. Chemical composition of the EOs was determined by GC/MS analysis. Their antibacterial potential and cytotoxicity were evaluated by microdilution and MTT assays, respectively. Statistical analysis was performed by Student’s t-test and one way ANOVA. Two the most abundant constituents of C. camphora cineoliferum EO were 1,8-cineole and sabinene, while in M. ericifolia EO the dominant were linalool and 1,8-cineole. MICs achieved against all tested strains were in the ranges 0.95±0.50 - 22.50±0.00 mg/mL and 0.65±0.00 - 23.35±7.80 mg/mL for the C. camphora cioneoliferum and M. ericifolia EOs, respectively. Statistical analysis showed that response to both oils has not differed between facultative and obligate anaerobes. Sensitivity pattern of the tested strains was different for the EOs and the positive control triple antibiotic paste (TAP): while E. faecalis and certain strains of S. salivarius were among the most sensitive to the oils, they were the least susceptible to the conventional antimicrobial TAP. Although the observed cytotoxicity of the EOs after 30 min of cell exposition was high (50.78-66.35% and up to 70% for C. camphora cioneoliferum and M. ericifolia EOs, respectively) it was lower than that of positive control (1.5% NaOCl, p<0.05). To conclude, both EOs showed promising antibacterial potential and achieved at least the same or even better biocompatibility than the conventional intracanal antimicrobials. Obtained results strongly encourage future research with an aim to formulate C. camphora cioneoliferum and M. ericifolia EO- based irrigants and medicaments, that could be used in endodontic practice.

AB  - Thioacetamide (TAA) is widely used to study liver toxicity accompanied by oxidative stress, inflammation, cell necrosis, fibrosis, cholestasis, and hepatocellular carcinoma. As an efficient free radical’s scavenger, C60 fullerene is considered a potential liver-protective agent in chemically-induced liver injury. In the present work, we examined the hepatoprotective effects of two C60 doses dissolved in virgin olive oil against TAA-induced hepatotoxicity in rats. We showed that TAA-induced increase in liver oxidative stress, judged by the changes in the activities of SOD, CAT, GPx, GR, GST, the content of GSH and 4-HNE, and expression of HO-1, MnSOD, and CuZnSOD, was more effectively ameliorated with a lower C60 dose. Improvement in liver antioxidative status caused by C60 was accompanied by a decrease in liver HMGB1 expression and an increase in nuclear Nrf2/NF-κB p65 ratio, suggesting a reduction in inflammation, necrosis and fibrosis. These results were in accordance with liver histology analysis, liver comet assay, and changes in serum levels of ALT, AST, and AP. The changes observed in gut microbiome support detrimental effects of TAA and hepatoprotective effects of low C60 dose. Less protective effects of a higher C60 dose could be a consequence of its enhanced aggregation and related pro-oxidant role.

AB  - The interest in natural products applications as antimicrobial agents is rapidly growing, mainly due to 
increasing microbial resistance to conventional therapeutics. Essential oils (EOs) seem to be especially 
attractive, since many of them possess high antimicrobial potential and none revealed resistance issue. EOs 
have already found applications in endodontic practice, mainly as sealers, but their antimicrobial potential 
has not been explored in this field yet. Taking this into account, the objective of this study was to investigate 
the antibacterial and antibiofilm efficacy of Cymbopogon martinii EO against bacterial strains relevant for 
endodontic therapy. Chemical composition of EO was determined by GC-MS/FID analysis. Antibacterial 
potential was screened in microdilution assay, detecting minimal inhibitory and bactericidal concentrations 
(MICs and MBCs) and performed on Enterococcus faecalis, Streptococcus mitis and Streptococcus 
sanguinis. Eradicating potential against biofilms preformed of each bacterial species as well as of all three 
bacteria, was determined in vitro in crystal violet (CV) assay. For screening of in situ effect against biofilm 
preformed in root canals of extracted teeth, the EO-based irrigant was formulated. Its antibiofilm potential 
was evaluated by plate counting (PC) assay, performed with single E. faecalis biofilm and multispecies 
biofilm composed of all three strains. Single E. faecalis biofilm was selected since it is the most relevant 
intracanal pathogen, while multispecies biofilm was screened to better mimic clinical conditions.
Chemical analysis revealed that geraniol was the most abundant constituent (83.5%), followed by geranyl 
acetate (8.4%). Determined MIC and MBC values were the lowest for E. faecalis (0.12 and 0.25 mg mL-1
, 
respectively), and the highest for S. sanguinis (2.95 and 5.90 mg mL-1
, respectively). CV assay pointed out 
that EO successfully eradicated in vitro preformed biofilms of E. faecalis and S. mitis (approximately 30% 
reduction), but had no effect on S. sanguinis and multispecies biofilms. EO-based irrigant used for 
determination of in situ antibiofilm potential was pre-screened for its physicochemical characteristics: a 
mean particle diameter and polydispersity index was 101 ± 3 nm and 0.36 ± 0.06, respectively. PC assay 
showed that eradicating potential of applied irrigant was weak against both E. faecalis and multispecies 
intracanal biofilm (reduction of logCFU was 0.76 and 0.52, respectively). However, successive irrigation 
with conventional dental irrigants (sodium hypochlorite and sterile saline), followed by C. martini EO-based 
irrigant, notably increased the biofilm reduction (1.89 and 1.69, respectively).
In conclusion, C. martini EO possesses notable antibacterial potential that could be further investigated for 
different dental applications.

abstract = "The interest in natural products applications as antimicrobial agents is rapidly growing, mainly due to 
increasing microbial resistance to conventional therapeutics. Essential oils (EOs) seem to be especially 
attractive, since many of them possess high antimicrobial potential and none revealed resistance issue. EOs 
have already found applications in endodontic practice, mainly as sealers, but their antimicrobial potential 
has not been explored in this field yet. Taking this into account, the objective of this study was to investigate 
the antibacterial and antibiofilm efficacy of Cymbopogon martinii EO against bacterial strains relevant for 
endodontic therapy. Chemical composition of EO was determined by GC-MS/FID analysis. Antibacterial 
potential was screened in microdilution assay, detecting minimal inhibitory and bactericidal concentrations 
(MICs and MBCs) and performed on Enterococcus faecalis, Streptococcus mitis and Streptococcus 
sanguinis. Eradicating potential against biofilms preformed of each bacterial species as well as of all three 
bacteria, was determined in vitro in crystal violet (CV) assay. For screening of in situ effect against biofilm 
preformed in root canals of extracted teeth, the EO-based irrigant was formulated. Its antibiofilm potential 
was evaluated by plate counting (PC) assay, performed with single E. faecalis biofilm and multispecies 
biofilm composed of all three strains. Single E. faecalis biofilm was selected since it is the most relevant 
intracanal pathogen, while multispecies biofilm was screened to better mimic clinical conditions.
Chemical analysis revealed that geraniol was the most abundant constituent (83.5%), followed by geranyl 
acetate (8.4%). Determined MIC and MBC values were the lowest for E. faecalis (0.12 and 0.25 mg mL-1
, 
respectively), and the highest for S. sanguinis (2.95 and 5.90 mg mL-1
, respectively). CV assay pointed out 
that EO successfully eradicated in vitro preformed biofilms of E. faecalis and S. mitis (approximately 30% 
reduction), but had no effect on S. sanguinis and multispecies biofilms. EO-based irrigant used for 
determination of in situ antibiofilm potential was pre-screened for its physicochemical characteristics: a 
mean particle diameter and polydispersity index was 101 ± 3 nm and 0.36 ± 0.06, respectively. PC assay 
showed that eradicating potential of applied irrigant was weak against both E. faecalis and multispecies 
intracanal biofilm (reduction of logCFU was 0.76 and 0.52, respectively). However, successive irrigation 
with conventional dental irrigants (sodium hypochlorite and sterile saline), followed by C. martini EO-based 
irrigant, notably increased the biofilm reduction (1.89 and 1.69, respectively).
In conclusion, C. martini EO possesses notable antibacterial potential that could be further investigated for 
different dental applications.",

AB  - OBJECTIVE The objective was to determine the antibiofilm efficacy of Cymbopogon martinii and Thymus zygis essential oils and to estimate the disruption potential of oil-based endodontic irrigants on the multispecies biofilm formed in the root canals of extracted teeth. DESIGN The essential oils were characterized (GC-MS), while their antibacterial and cytotoxic properties were detected by microdilution and MTT assays. Particles sizes and polydispersity indices were determined for the irrigants. The isolates from root canals of pediatric patients were identified (MALDI-TOF). The multispecies biofilms were formed from Streptococcus mitis, Streptococcus sanguinis and Enterococcus faecalis. Antibiofilm properties of the essential oils and irrigants were determined by crystal violet and plate counting assay. Statistical analysis was performed by one-way ANOVA. RESULTS The screening of biofilm biomass revealed a disruption potential of C. martinii essential oil. The plate counting assay showed the efficacy of both oils in diminishing cell viability: high in biofilms (reduction of log10CFU was 2.75-2.87) and moderate in the planktons formed above. The essential oil-based irrigants showed the same antibiofilm activity as in the control (1.5 % sodium hypochlorite) for C. martini and almost 2-fold higher for T. zygis. Successive irrigations with 1.5 % sodium hypochlorite, saline and an oil-based irrigant was more efficient for C. martini than for the control (reductions of log10CFU was 1.69 and 1.14, respectively). CONCLUSIONS Notable activities achieved by essential oils and oil-based irrigants, particularly regarding C. martini, against the biofilm consisting of S. mitis, S. sanguinis, and E. faecalis, are expected to encourage further research in endodontics.

AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - Medicinal plant Gentiana lutea is considered as an official drug for gastrointestinal disorders in many pharmacopoeias. Its uncontrolled overexploitation led to the protection regime and encouraged development of in vitro culture. The aim of this work was to chemically characterize root and leaf methanol extracts of plant grown in plantation and in vitro conditions, and to determine their antigenotoxicity against heterocyclic aromatic amines IQ and PhIP, the food-borne mutagens that are formed during high temperature cooking of protein-reach foods. High yields and growth ratios were determined for in vitro plants. Higher content of polyphenols and flavonoids were determined in aerial parts, while UPLC-MS/MS analysis pointed at the richness of in vitro grown shoot extract (GLvS) in active constituents, and high amounts of gentiopicroside in all tested extracts. Notable amounts of sweroside were detected in plantation root extract (GLR) and in GLvS, and of loganic acid in plantation leaf extract (GLL) and GLvS. Two experimental models for genotoxicity/antigenotoxicity study, i.e. SOS/umuC test with metabolic activation (addition of rat liver S9 fraction) and alkaline comet assay on hepatocellur carcinoma HepG2 cells indicated dual effects: genotoxic of high and antigenotoxic of lower non-genotoxic doses. While in vitro extracts were genotoxic in both models, plantation extracts were active only in SOS/umuC with S9. In contrast, inhibition of genotoxicity was observed in both models for all extracts (up to 83 %). Results of DPPH assay indicated that antioxidativity could be responsible for antigenotoxic properties. In conclusion, genoprotective effect encourages further investigation of antigenotoxicity, while high growth ratio and richness of GLvS in active compounds justify the use of in vitro cultivation method.

AB  - Non-diabetic and alloxan-induced diabetic rats were fed with standard laboratory food enriched with 20% virgin coconut oil for 16 weeks. In non-diabetic animals coconut oil improved insulin sensitivity and ability to control glycaemia and decreased the serum triglycerides for almost 50% in comparison with controls. Supplementation with coconut oil caused liver steatosis in both non-diabetic and diabetic animals. However, the severity of steatosis was lower in diabetic animals compared to non-diabetic animals. Coconut oil had no effects on heart histology, ascending and abdominal aorta wall thickening and atherosclerotic plaques development neither in non-diabetic nor in diabetic animals. While alloxan treatment caused Type I diabetes in rats, supplementation with coconut oil in combination with the alloxan unexpectedly resulted in Type II diabetes. The development of severe insulin resistance and deterioration in serum lipid profile implied that the use of coconut oil is contraindicated in diabetic condition.

AB  - Previously chemically characterized Juniperus communis essential oil (EO) and post-distillation waste (PDW) were tested for cytotoxicity and antimicrobial activity against food contaminants. Microdilution assay showed that PDW induced moderate antifungal (minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values, ranging between 0.118-0.900 mg mL-1), and an antibacterial effect against Listeria monocytogenes (MIC and minimum bactericidal concentration (MBC) were 0.39 and 0.74 mg mL-1, respectively). Combinations of EO/PDW with selected antibiotics induced synergistic antilisterial activity in the checkerboard assay. The MTT assay determined that cytotoxicity against colon cancer cells was high for the EO but negligible for PDW (IC50 values were 0.087-0.106 and 1.450-6.840 mg mL-1, respectively). The selectivity indices indicated high selectivity of PDW against tested fungi and L. monocytogenes. In the adhesion-inhibition assay, PDW reduced in vitro adhesion of L. monocytogenes to colon cells (29-62% of inhibition). In conclusion, PDW exhibited an antimicrobial effect against important food spoilage and poisoning fungi and L. monocytogenes, and also reduced in vitro adhesion of L. monocytogenes to colon cells.

abstract = "Previously chemically characterized Juniperus communis essential oil (EO) and post-distillation waste (PDW) were tested for cytotoxicity and antimicrobial activity against food contaminants. Microdilution assay showed that PDW induced moderate antifungal (minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values, ranging between 0.118-0.900 mg mL-1), and an antibacterial effect against Listeria monocytogenes (MIC and minimum bactericidal concentration (MBC) were 0.39 and 0.74 mg mL-1, respectively). Combinations of EO/PDW with selected antibiotics induced synergistic antilisterial activity in the checkerboard assay. The MTT assay determined that cytotoxicity against colon cancer cells was high for the EO but negligible for PDW (IC50 values were 0.087-0.106 and 1.450-6.840 mg mL-1, respectively). The selectivity indices indicated high selectivity of PDW against tested fungi and L. monocytogenes. In the adhesion-inhibition assay, PDW reduced in vitro adhesion of L. monocytogenes to colon cells (29-62% of inhibition). In conclusion, PDW exhibited an antimicrobial effect against important food spoilage and poisoning fungi and L. monocytogenes, and also reduced in vitro adhesion of L. monocytogenes to colon cells. The results indicate that J. communis PDW could be considered as natural preservative against food spoilage and poisonous fungi, and as an adjuvant to conventional therapy of listeriosis",

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat liver and serum lipid status. Animals were divided into two groups with 8 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. On the last day of the experiment animals were killed, and blood and liver tissue were collected. In serum we measured the levels of total cholesterol (TC), high-density lipoproteins (HDL), non-HDL lipoproteins, triglycerides (TG), aspartate aminotransferase (9\.ST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). We also measured both liver and serum levels of high mobility group protein B 1 (HMGB 1) and haptoglobin (HP), as ,.vell as the liver level of NF-KB p65/ p-NF-KB p65 transcription factor, together with the histopathology analysis on liver slices and liver Comet assay. The results show that coconut oil do not change serum TC and HDL, but reduces non-HDL and TG levels (10% and 50%, respectively) comparing to control. As a result, atherogenic index of serum (AI) is strongly reduced in VCO group versus control. As for the liver status, results show that coconut supplementation increases AST, ALT and ALP levels in VCO group (50%, 30% and 60%, respectively) comparing to control. This effect is caused by the accumulation of coconut oil fat in liver, as confirmed by the histopathology showing signs of mild nonalcoholic steatohepatitis in VCO group, followed with the increased %of DNA in comet tail. The liver inflammation in VCO group is further demonstrated with the liver HP, HMGBl and p-NF-KB p65 level increase, and increase in nuclear level ofNF­kB p65, but not accompanying serum HP and HMGBl increase. In conclusion, our results show that coconut oil supplementation, despite causing mild and localized steatohepatitis, also lowers serum atherogcnic index, a predictor of cardiovascular risk.

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat glucose homeostasis. Animals were divided into two groups with 6 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. We measured fasting glycemia once a week during the entire experiment. In the last week of the experiment, we performed an oral glucose tolerance test (OGTT) and an intraperitoneal insulin tolerance test (ITT). On the last day of the experiment the fasting insulin and glyc8mia were measured in the blood of animals. The results show that coconut oil reduces weekly glycemia in VCO animals compared with controls. This effect reaches its maximum after the first two weeks of the experiment, and then slowly decreases and disappears over time of next eight weeks. As a result, the glycemia of control and VCO animals do not differ in last six weeks of the experiment. The area under the curve (AUC) presenting glycemia during whole the experiment is significantly lower in VCO animals than in the controls. The hypoglycemic effect of coconut oil is obviously dose-dependent since the amount of food (and therefore the coconut oil) that the animals eat decreases over the time. The results of the oral glucose tolerance test show that the OGTT AUC of VCO animals is significantly lower than the controls, and same is true for the insulin tolerance test. Finally, glycemia and insulin concentration in serums sampled on the last day of the experiment do not differ between VCO and Control groups, so accordingly neither HOMA-IR I and 2 (Homeostatic model assessment of insulin resistance) nor QUIC.Kl ( Quantitative Insulin Sensitivity Check Index). In conclusion, our results show beneficial effects of long-term high-dose coconut oil supplementation on rat glucose homeostasis.
