To verify the influence of ozone (O) therapy on an experimental model of rheumatoid arthritis (RA), 30 male Wistar rats were randomly allocated to 2 groups, control (C) and treatment (T), and subdivided into control (C12, C48, C72) and treatment (T12, T48, T72) groups. RA was induced by administration of collagenase plus complete Freud's adjuvant in the knee joint region. The animals were treated with ozone therapy (1 ml O injection in the knee i.a.) according to group assignment: T12, 2 h; T48, 2 and 24 h; and T72, 2, 24, and 48 h post-RA induction. The different animal groups were euthanized 12, 24, or 72 h post-RA induction, respectively. Synovial exudate levels of IL-10, IL-12p70, TNF-α, INF-γ, and MCP-1 were assessed by flow cytometry, and histopathological analysis of the knee cartilage was conducted. Ozone therapy effectively decreases inflammation, reducing IL-12 and TNF-α, and increasing IL10. O did not statistically affect INF-γ or MCP-1 levels. More expressive results were obtained with group T72, i.e., treated 2, 24, and 48 h post-RA induction, which indicates that longer-term ozone treatment is more effective than a single acute application. Ozone therapy effectively reduced inflammation with effects, at least in part, mediated through reduction of pro-inflammatory cytokines and activation of IL-10 anti-inflammatory cytokine.

Background: Intracanal medicament (ICM) eliminates remaining bacteria and their toxins that were not removed by chemomechanical preparation during endodontic treatment.
Aim: The aim of this study was to compare and evaluate the removal of ozonated oil-based, silicone oil-based, and distilled water-based ICM with two calcium chelators, i.e.

The aim was to evaluate nerve healing using immunohistochemical, histological, and functional techniques and to compare the effects of two different therapeutic ozone application methods by perineural and intraperitoneal ozone treatment in rats with a crush injury model of sciatic nerve. Forty male Sprague Dawley rats were divided into four subgroups of ten rats each: (1) Control group: The left sciatic nerve incised and closed without crush injury, no treatment; (2) Paralyzed group: Crush injury to the left sciatic nerve, no treatment; (3) Perineural ozone group: Crush injury to the left sciatic nerve, treated with perineural ozone therapy; (4) Intraperitoneal ozone group: Crush injury to the left sciatic nerve, treated with intraperitoneal ozone therapy. The treatments were administered for a 14-day period.

Background: The inappropriate use of antibiotics increases the costs of treatment, antibiotic resistance, increased disease length and duration of hospital stay.
Objectives: The aim of this study was investigating the pattern of use and effectiveness of the Linezolid in COVID-19 hospitalized patients.
Methods: In this retrospective cross-sectional analytical study was carried out from February 2020 (from the beginning of the pandemic in Iran) to the end of September 2020, 32 COVID-19 patients that used Linezolid were included.

In the United States (US), neonatal intensive care units (NICUs) monitor and treat newborns for a variety of adverse health concerns including preterm status, respiratory distress and restricted growth. As such, NICU admission is an integrated measure of neonatal risk. We linked 2018 US national birth registry NICU admission data among singleton births with satellite and modelled air pollution levels for the month prior to birth to examine whether late-pregnancy exposure to ambient air pollutants is associated with adverse neonatal health outcomes.

The action of ozone in medicine is a subject of interest and lively, controversial debates. Its mechanisms of action are still far from fully understood. However, it is possible that ozone triggers a series of dynamics in living organisms related to chaos, multi-stable phenomena, and oscillatory processes.
