Ameliorating orthodontic relapse using laser bio-stimulation and mesenchymal stem cells in rats.

Background: Orthodontic relapse is a frequent problem that many patients experience. Although orthodontic therapy has advanced, recurrence rates can still reach 90%. We undertook a study to look at the possibilities of laser bio-stimulation and stem cells because they have showed promising outcomes in lowering recurrence rates.

Antifungal Activity of Bioactive Compounds Produced by the Endophytic Fungus . (JN227071.1) against .

Biologically active natural compounds are molecules produced by plants or plant-related microbes, such as endophytes. Many of these metabolites have a wide range of antimicrobial activities and other pharmaceutical properties. This study aimed to evaluate () the antifungal activities of the secondary metabolites obtained from against the pathogenic fungus .

Galangin-Loaded Gold Nanoparticles: Molecular Mechanisms of Antiangiogenesis Properties in Breast Cancer.

Angiogenesis is important for tissue during normal physiological processes as well as in a number of diseases, including cancer. Drug resistance is one of the largest difficulties to antiangiogenesis therapy. Due to their lower cytotoxicity and stronger pharmacological advantage, phytochemical anticancer medications have a number of advantages over chemical chemotherapeutic drugs.

Zinc Chloride Can Mitigate the Alterations in Metallothionein and Some Apoptotic Proteins Induced by Cadmium Chloride in Mice Hepatocytes: A Histological and Immunohistochemical Study.

The heavy metal cadmium is extremely harmful to both humans and animals. Zinc supplementation protects the biological system and reduces cadmium-induced toxicity. This study aimed to determine whether zinc chloride (ZnCl) could protect male mice with the damaged liver induced by cadmium chloride (CdCl).

Effects of hyperoxia on the permeability of 16HBE14o- cell monolayers--the protective role of antioxidant vitamins E and C.

The use of hyperoxia for critically ill patients is associated with adverse impacts resulting in lung injury accompanied by inflammation. The aim of this study was to evaluate aspects of mechanisms that contribute to hyperoxia-induced disruption of the epithelial permeability barrier, and also the protective effects of the antioxidants α-tocopherol and ascorbate. 16HBE14o- cells were cultured as monolayers at an air-liquid interface for 6 days, after which transepithelial electrical resistance reached 251.

Hyperoxia-induced ciliary loss and oxidative damage in an in vitro bovine model: the protective role of antioxidant vitamins E and C.

Although elevated oxygen fraction is used in intensive care units around the world, pathological changes in pulmonary tissue have been shown to occur with prolonged exposure to hyperoxia. In this work a bovine bronchus culture model has been successfully used to evaluate the effects of hyperoxia on ciliated epithelium in vitro. Samples were cultured using an air interface method and exposed to normoxia, 21% O(2) or hyperoxia, 95% O(2).
