Stent deployments with geographical miss (GM) are associated with increased risk of target-vessel revascularization and periprocedural myocardial infarction. The aim of the current study was to investigate the underlying biomechanical mechanisms for adverse events with GM. The hypothesis is that stent deployment with GM [longitudinal GM, or LGM (i.e., stent not centered on the lesion); or radia...
BACKGROUND The aim of this study was to evaluate the changes in perioperative oxidant-antioxidant balance in ONCABG. METHODS Twenty-three patients were included in this study. Serum total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI) values were assessed preoperatively, at 20 minutes after aortic clamping and at 30 minutes, 6 hours, and 48 hours after ...
Sirtuin-1 (SIRT1) is a longevity factor in mammals initiating the cell survival mechanisms, and preventing ischemic injury in heart. In the etiopathogenesis of heart failure (HF), impairment in cardiomyocyte survival is a notable factor. Oxidative stress comprises a critical impact on cardiomyocyte lifespan in HF. The aim of the present study was to investigate SIRT1 expression in patients with...
The communication standards tend to be extremely technical and tedious documents defining the very behaviour of a given system. The IEEE 802 set of wireless communications standards for the Personal/Local/ Metropolitan Area Network mainly specify the two lowest OSI layers (physical and link) of the system, yet they comprise hundreds of pages requiring time and trained personnel to be comprehend...
Acne vulgaris is a common skin disease and has complex pathogenesis. There no enough data related with oxidative stress in acne vulgaris. We purposed to assess total oxidant antioxidant status included 32 patients 35 healthy controls this study. Global Grading System (GAGS) scores were calculated. Serum (TOS) (TAS) levels evaluated index (OSI) was calculated by proportion of the TOS TAS. Mean G...
The phosphoinositide 3-kinase (PI3K)/AKT/mTOR pathway is frequently activated in human cancers, and mTOR is a clinically validated target. mTOR forms two distinct multiprotein complexes, mTORC1 and mTORC2, which regulate cell growth, metabolism, proliferation, and survival. Rapamycin and its analogues partially inhibit mTOR through allosteric binding to mTORC1, but not mTORC2, and have shown cl...
BACKGROUND Apical periodontitis (AP) is an inflammatory disease affecting periradicular tissues. It is a widespread condition but its etiopathogenetic mechanisms have not been completely elucidated and the current treatment options are not always successful. PURPOSE To compare oxidative stress (OxS) levels in the saliva and the endodontium (root canal [RC] contents) in patients with different...
Aquatic ectotherms face the continuous challenge of capturing sufficient oxygen from their environment as the diffusion rate of oxygen in water is 3 x 10(5) times lower than in air. Despite the recognized importance of oxygen in shaping aquatic communities, consensus on what drives environmental oxygen availability is lacking. Physiologists emphasize oxygen partial pressure, while ecologists em...
