Assessing the impact of dental restorative materials on fibroblast cells: an immunohistochemical and ELISA analysis.

In this study, our aim was to investigate the effects of restorative materials such as composite, compomer and high viscosity glass ionomer, which are frequently used in dentistry, on L929 fibroblast cells by evaluating the oxidative stress parameters, pro- and anti-inflammatory cytokines, and apoptosis markers. L929 fibroblast cells were cultured, and dental filling materials were applied in two doses (50 and 100 µl). Immunohistochemical staining was performed for experimental groups with Anti-Bax and Anti-Caspase 9 antibodies.

The effects of cisplatin and jaceosidin on SH-SY5Y neuroblastoma cells: an electron microscopic, molecular and biochemical study.

In this study, our aim was to show both the single and combined effects of cisplatin and jaceosidin in SHSY-5Y neuroblastoma cells. For this purpose, we used MTT cellular viability assay, Enzyme-Linked Immunosorbent Assay (ELISA), Transmission Electron Microscopy (TEM), Immunofluorescence Staining Assay (IFA) and Western blotting (WB) assay. According to MTT findings, IC50 dose was detected as 50 µM cisplatin and 160 µM jaceosidin co-application.

Two flavonoids, baicalein and naringin, are effective as anti-inflammatory and anti-oxidant agents in a rat model of polymicrobial sepsis.

Introduction: In this study, our aim was to investigate the possible protective and therapeutic effects of these two flavonoids, baicalein, and naringin, in 50 and 100 mg/kg doses applied both before and after cecal ligation and puncture (CLP) procedures in a polymicrobial sepsis rat model, and evaluate the possible contribution of oxidative and inflammatory markers by immunological, biochemical, molecular, and histopathological methods.

Methods: Sixty-six Wistar albino rats were divided into 11 groups. The pro-inflammatory (TNF-alpha, IL-1-beta, and IL-6) and anti-inflammatory (TGF-beta and IL-10) cytokine levels were measured by ELISA technique.

Anti-oxidant and anti-inflammatory effects of apigenin in a rat model of sepsis: an immunological, biochemical, and histopathological study.

Objective: We hypothesize that apigenin may inhibit some cellular process of sepsis-induced spleen injury and simultaneously improve inflammation and oxidative stress. Therefore, the aim of this study was to investigate the potential protective effects of apigenin in a polymicrobial sepsis rat model of by cecal ligation and puncture.

Materials And Methods: 64 female Wistar albino rats were divided into 8 groups.

Investigation of Helicobacter pylori antigen in stool samples of patients with upper gastrointestinal complaints.

Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints.

The relationship between estrogen receptors and microtubule dynamics in post-menopausal rat brain.

Introduction: Estrogen is one of the most important regulators of neuron function. There is a broad consensus that a loss of estrogen is associated with neurodegeneration in the hippocampus which leads to cognitive impairment. Hematopoietic-Pbx-interaction-protein (HPIP) is a novel scaffolding protein which interacts with microtubules and estrogen receptors.

The protective effects of beta-carotene against ischemia/reperfusion injury in rat ovarian tissue.

Introduction: Beta-carotene is a well-known antioxidant and precursor of Vitamin A that has a preventative role in the oxidative damage process. Our aim was to investigate the possible preventive effects of beta-carotene on oxidative damage via experimental ischemia and ischemia-reperfusion models in rat ovaries.

Materials And Methods: A traumatic vascular clamps were used for 3h to induce ischemia (Group 2, 3, 4, 5, 6, 7).

Hepatoprotective effect of 17β-estradiol as antioxidant modulators against stress damage.

Background: Liver is one of the most important organs affected by exercise. According to the literature a few study to date has investigated the effects of estrogen supplementation on exercise-induced oxidative stress in liver tissue of rats.

Objectives: We aimed to investigate the effects of estrogen supplementation on oxidative stress markers in liver tissue of exercised rats.
