According to the results, ozone/oxygen therapy and debridement with Piezoelectric surgery for BRONJ treatment is a safe procedure with successful outcomes.

According to the results, ozone/oxygen therapy and debridement with Piezoelectric surgery for BRONJ treatment is a safe procedure with successful outcomes.

The therapeutic application of ozone and its derivatives in the dental field has been used for many purposes. However, there has yet to be a consistent evaluation of the outcomes, due to the lack of standardization of the treatment operating procedures.

The keywords "ozone", "ozonated", "ozonation" "ozonized", "ozonization", "dentistry", "periodontology", "oral surgery", "oxygen-ozone therapy" were used to perform a literature review using PubMed, Cochrane, Google Scholar, Zotero databases with the temporal restriction for manuscripts published between 2010 and 2020. Clinical trials and case reports of good, neutral, as well as negative results related to ozone treatment specifications were evaluated.

A better understanding of the mechanisms of action of this bio-oxidative therapy could open new horizons related to the personalization of treatments and the quality of dental care. The critical condition to achieve these goals is an improved knowledge of the qualitative/quantitative characteristics of ozone and its derivatives.

Prior cardiovascular event and kidney dysfunction are both strong risk factors for coronary artery disease. The aim of this study is to assess coronary atherosclerotic burden in a large population of patients undergoing coronary angiography, according to prior cardiovascular event or chronic kidney disease.

We evaluated 700 consecutive patients who underwent coronary angiography (CA). Serum creatinine to estimate glomerular filtration rate (eGFR) was measured. Clinically significant coronary artery disease (CAD) was defined by the presence of a coronary lesion resulting in a luminal stenosis >50%. see more For the purpose of the study, the whole population was divided into 4 subgroups according to the presence/absence of eGFR <60 ml/min/1.73 m2 or prior cardiovascular event eGFR≥60/no event (Group A), eGFR≥60/yes event (Group B), eGFR<60/no event (Group C), eGFR<60/yes event (Group D).

As expected, patients in group D had the worst clinical and biochemical profile. These patients also presented the highest values of urinary albumin creatinine ratio (ACR, p<0.001) and the lowest values of eGFR (p<0.01). One-hundred-ninety-six patients had three-vessel disease. Patients who had undergone PCI procedure showed a lower eGFR as compared to patients who had not (p=0.009). Considering group A as reference, the risk of having three-vessel disease was increased in group B (OR= 2.09; 95% CI 1.37-3.19), in group C, (OR= 1.80; 95% CI 1.04-3.14), and finally in group D (OR= 3.35; 95% CI 2.01-5.58). The risk carried by group C was not significantly different from that carried by Group B OR= 0.86; 95% CI 0.5-1.5.

In our study, low eGFR seems to have the same excess risk of prior CV event.

Oxidative stress is one of the main factors leading to myocardial cell damage, and the redox imbalance promotes apoptosis. Therefore, the purpose of this study was to explore the protective effect of PrxII on H2O2-induced H9c2 cell injury.

The overexpressed PrxII cell model was constructed by virus. The H9c2 cells were treated with H2O2, and the supernatant and cells were collected. Then, the chymotrypsin-like activity, caspase-like activity, and trypsin-like activity were detected by the kit, and the expressions of P21, P27, and P53 were detected by the ELISA method. Finally, the expressions of antioxidant factors, apoptosis-related factors, and AMPK/Sirt1 signaling pathway were detected by Western blot and Real-time polymerase chain reaction (PCR).

Overexpression of PrxII inhibited the decrease of enzyme activity induced by H2O2, promoted the expressions of anti-oxidation factors GPX1, GPX2, and GSX, and inhibited the expressions of apoptosis-related factors P21, P27, and P53, and activated AMPK/Sirt1 pathway.

Overexpression of PrxII can activate the AMPK/Sirt1 pathway, thereby inhibiting H2O2-induced oxidative stress and slowing apoptosis.

Acute myocardial infarction (AMI) is a severe fatal disease throughout the world. Myocardial IR limits the recovery of impaired cardiac function in AMI patients. This study aims to elucidate the role of long non-coding RNA (lncRNA) HOTAIR in myocardial ischemia-reperfusion (IR) and the underlying mechanism, thus providing a novel therapy for AMI.

Myocardial IR model in mice was firstly constructed by LAD. Plasma levels of LDH, CK-MB, HOTAIR, and microRNA-126 in mice were detected. Subsequently, in vitro HR model was constructed in H9c2 cells. Regulatory effects of HOTAIR on proliferative ability, LDH release, and Caspase-3 activity in H2O2-induced H9c2 cells were determined. Relative levels of inflammatory factors in in vitro HR model were measured by enzyme-linked immunosorbent assay (ELISA). The regulatory loop HOTAIR/microRNA-126/SRSF1 was finally verified by Dual-Luciferase reporter assay.

LDH and CK-MB were significantly released in mice with myocardial IR. HOTAIR was upregulated, while microRNA-126 was downregulated in IR mice and H2O2-induced H9c2 cells. Overexpression of HOTAIR stimulated proliferative ability, LDH release, and Caspase-3 activity in H2O2-induced H9c2 cells. Besides, overexpression of microRNA-126 inhibited the release of inflammatory factors in H9c2 cells undergoing HR induction. The regulatory loop HOTAIR/microRNA-126/SRSF1 was identified to influence IR development.

HOTAIR aggravates myocardial IR by competitively binding SRSF1 with microRNA-126.
