The effect of periodontal therapy on neopterin and vascular cell adhesion molecule-1 levels in chronic periodontitis patients with and without acute myocardial infarction: a case-control study

The presence of neopterin in gingival crevicular fluid (GCF) is a marker for local and acute immune activation, and the presence of vascular cell adhesion molecule (VCAM-1) in GCF is accepted as a marker for chronic vascular inflammation. Objectives: This study aimed to evaluate effects of periodontal treatment on GCF levels of neopterin and VCAM-1 in patients with chronic periodontitis (CP) with acute myocardial infarction (AMI) compared with systemically healthy CP patients. Material and methods: Sixty subjects (20 CP patients with AMI, 20 healthy CP patients, and 20 healthy controls) were included. GCF samples were analyzed at baseline and after 3 and 6 months, and the probing pocket depth (PD), clinical attachment level (CAL), bleeding on probing, gingival (GI) and plaque (PI) indices were recorded. We determined neopterin and VCAM-1 levels (concentration and total amount) using enzyme-linked immunosorbent assay (ELISA). No significant differences were seen between the AMI+CP and CP groups for PI, GI, GCF levels of neopterin and VCAM-1 at baseline. Results: The number of teeth with 5 mm≤CAL<7 mm and CAL≥7 mm were significantly increased in the AMI+CP group at baseline. There were no significant differences between the AMI+CP and CP for PI, CAL, GCF volumes, and the AMI+CP group had the highest clinical improvement in the number of teeth with 5 mm≤CAL<7 mm at the sixth month. There were significant positive correlations between clinical periodontal inflammation and the presence of neopterin and VCAM-1 in GCF prior to and following periodontal treatment, and between the GCF volume and clinical parameters. Conclusions: Data suggest that the total amount and concentration of neopterin and VCAM-1 in GCF seemed to be closely associated with periodontal disease severity in CP patients with AMI. Moreover, the results of our study demonstrate that the past periodontal status is potentially correlated between groups, with similar periodontal disease severity

High osmolar contrast medium causes mild oxidation in liver, bladder, and ovary tissues from rats: vitamin C has protective role

The purpose of this study was to investigate effects of ionic highosmolar contrast medium on oxidative metabolism in liver, urinary bladder, and ovary tissues and to obtain information about possible protective effects of vitamin C. Twenty-one female rats, 14 weeks old, were used in this study. They were divided into three groups of seven rats: Sham (group I), contrast (group II), contrast ? vitamin C (group III). Vitamin C was given orally to the animals in group III during the study period. On the fifth day, contrast medium was given via intravenous infusion as a single dose to the animals in groups II and III. On the sixth day of the study, the animals were killed with anesthesia by ketamine hydrochloride. Then, their liver, bladder, and ovary tissues were removed to measure analyses parameters. Our results suggested that contrast medium led to some increases in malondialdehyde levels in the liver, bladder, and ovary tissues and that vitamin C prevented these increases in the tissues. Nitric oxide level also was found to increase in the contrast-treated animals and vitamin C prevented this increase in the liver tissue. Ionic high-osmolar contrast medium leads to weak oxidant stress in rat liver, bladder, and ovary tissues, and vitamin C prevents this oxidant stress

Mesophilic Anaerobic Co-digestion of Olive-Mill Waste With Cattle Manure: Effects of Mixture Ratio

The co-digestion of agri-food by-products and livestock manure is a feasible alternative for waste management and the recovery of biogas provides an option to generate renewable energy. A series of batch experiments were carried out in order to investigate the mesophilic anaerobic co-digestion of two-phase olive-mill waste (2POMW) and cattle manure (CM) in different mixtures (2POMW:CM = 50:50; 60:40; 75:25; 85:15). In addition, the biodegradability of the co-substrates was studied in order to analyze the performance of the co-digestion process. The results obtained in this study indicate that 2POMW has a low biodegradability since a high soluble organic matter concentration and a low accumulated methane production were obtained at the end of the corresponding biodegradability test. However, CM is more easily biodegradable in mesophilic anaerobic conditions. The co-digestion of both wastes produced an enhancement of the hydrolytic-acidogenic phase, increasing the organic matter potentially bioavailable as volatile fatty acids (VFAs) and the biogas productivity, as a consequence of the subsequent degradation of VFAs by methanogens. However, an accumulation of VFA, principally propionic acid, was observed in the reactors with higher proportions of 2POMW. The volatile solids (VS) removal increased with the 2POMW percentage of the mixture up to 75% fresh weight. The increase of 2POMW above 75% led to a decrease in total VS removal. Moreover, a decrease in methane production was observed for the 85:15 mixture, as a consequence of the high concentration of propionic acid, which is a known inhibitor of methanogenesis. The maximum cumulative methane production and methane yield were achieved in the 75:25 mixture with values of 18.70 L and 112.40 LCH4/kgVS(added), respectively. Compared with 2POMW, the co-digestion produced an increase of 264-319% in the volume of accumulated methane (L), 293-351% in the methane yield (LCH4/kgVS(added)) and 312-342% based on the VS consumed (LCH4/kgVS(removed)). These results suggest that the mixture of these agro-industrial by-products could be effective to enhance biogas production and organic matter removal from 2POMW

Two-Stage Fungal Pre-Treatment for Improved Biogas Production from Sisal Leaf Decortication Residues

Sisal leaf decortications residue (SLDR) is amongst the most abundant agro-industrial residues in Tanzania and is a good feedstock for biogas production. Pre-treatment of the residue prior to its anaerobic digestion (AD) was investigated using a two-stage pre-treatment approach with two fungal strains, CCHT-1 and Trichoderma reesei in succession in anaerobic batch bioreactors. AD of the pre-treated residue with CCTH-1 at 10% (wet weight inoculum/SLDR) inoculum concentration incubated for four days followed by incubation for eight days with 25% (wet weight inoculum/SLDR) of T. reesei gave a methane yield of 0.292 ± 0.04 m3 CH4/kg volatile solids (VS)added. On reversing the pre-treatment succession of the fungal inocula using the same parameters followed by AD, methane yield decreased by about 55%. Generally, an increment in the range of 30–101% in methane yield in comparison to the un-treated SLDR was obtained. The results confirmed the potential of CCHT-1 followed by Trichoderma reesei fungi pre-treatment prior to AD to achieve significant improvement in biogas production from SLDR

Can the de Ritis Ratio (AST/ALT) Be Used to Predict Colon Cancer Stages?

Purpose: The De Ritis ratio (Aspartate transaminase/alanine transaminase) is a critical prognostic factor for some kinds of malignant tumors. Nevertheless, the De Ritis ratio’s prognostic value in preoperative colon cancer staging is unclear. The purpose of this research was to determine the De Ritis ratio and its prognostic significance for colon cancer. Materials and Methods: The clinicopathological data of 271 individuals with malign colon cancer were analyzed retrospectively at a single center from January 2010 to January 2018. The relationship between the De Ritis coefficient and clinicopathological findings in patients was evaluated before treatment. To compare the groups, the Mann-Whitney U test and the Kruskal Wallis test were performed. Results: The results indicated that there were no statistically significant differences between the groups in terms of pre-treatment De Ritis ratio assessment as a staging, localization, tumor diameter, lymph node metastasis, age, and overall survival. However, differences in T staging between groups of male participants were shown to be statistically significant. Conclusions: The De Ritis ratio evaluation before treatment was not found as an independent variable prognostic factor for the diagnosis and staging of colon cancer. However, future studies may demonstrate the significance of the De Ritis ratio with more participants
