In examined groups of healthy people as well as in persons suffering from a periodontitis of a different severity-degree with concomitant affections and without them the PO2 in the blood is defined by the concentration of K+ and Cl- in erythrocytes and in blood as well as by the relation between the
BACKGROUND
Studies have shown that psychologic stress plays a significant role in the outcome of many diseases. The present study is designed to investigate the effect of stress on experimental ligature-induced periodontal disease in rats by means of a variable moderate chronic stress
OBJECTIVE
To discuss the expression of RUNX2 and MDM21 in rats with periodontitis under the chronic intermittent hypoxia.
METHODS
A total of 32 SD healthy rats were randomly divided into four groups, with 8 rats in each group. The molecular biological techniques of immunohistochemistry, RT-PCR and

This study evaluates the expression of interleukin-18 (IL-18) and hypoxia-inducible factor (HIF)-lα in rat periodontitis model exposed to normoxia and chronic intermittent hypoxia (CIH) environments. The possible correlation between periodontitis and obstructive sleep apnea-hypopnea
Background: The aim of this study was to investigate the effects of exposure to continuous (CH) and intermittent (IH) hypoxia on biomechanical properties of the mandible and periodontal tissue of animals submitted to experimental
Hypoxia-inducible angiogenic pathway involving hypoxia inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF) and tumour necrosis factor- alpha (TNF-α) may regulate several biological processes related to inflammation. The present study aimed to assess the effect OBJECTIVE
Oral epidemiologic investigations in China western territory have showed that the immigrants in the plateau have a higher morbidity with periodontitis. To find the possible relationship between the pathogenesis of periodontitis and altitude hypoxia, we designed a periodontitis rat model
OBJECTIVE
To observe the activity of superoxide dismutase (SOD) in rabbit periodontitis model in normoxia and hypoxia environment, and to research the pathogenesis of periodontal diseases at high altitude.
METHODS
Fourty male rabbits were randomly divided into four groups: Normoxia control group,
ADAMTS (A disintegrin-like and metalloproteinase with thrombospondin) are a family of proteinases that are structurally similar to the family of matrix metalloproteinases with critical roles in damage and repair of the extracellular matrix. Their functions are closely related to Smoking causes pathological changes in all tissues, including gingiva and alveolar bone. The aim of present study was to evaluate apoptotic tissue alterations and tissue destruction in smoker and non-smoker periodontitis patients and healthy Periodontitis is defined as inflammation affecting the supporting tissue of teeth. Periodontal pathogens initiate the disease and induce inflammatory host response. Hypoxia may accelerate the process by producing pro-inflammatory factors. The aim of this study is to investigate the effect of
Present study suggests that diseased sites of periodontitis with stage 3 grade B and C had decreased fibroblast cell density, hypoxia-inducible factor (HIF) and vascular endothelial growth factor (VEGF) expressions while increased inflammatory cell counts compared to both healthy sites of
Oxidative stress is characterized by an accumulation of reactive oxygen species (ROS) and plays a key role in the progression of inflammatory diseases. We hypothesize that hypoxic and inflammatory events induce oxidative stress in the periodontal ligament (PDL) by activating NOX4. Human primary PDL
A20 exerts an anti-osteoclastogenic effect through the inhibition of NF-κB signalling in periodontitis. It also regulates autophagy via ubiquitin modification. This study was aimed at exploring the relationship between A20 and autophagy in anti-osteoclastogenesis in human periodontal BACKGROUND
Pro-inflammatory markers are seen to increase in inflammatory diseases like periodontitis. Detecting an increase in these markers is one of the diagnostic modality. One such marker, which can be detected, is the ceruloplasmin. Ceruloplasmin induces hypoxia and generates oxygen radicals at
