Infliximab trough levels among patients with inflammatory bowel disease in correlation with infliximab treatment escalation: a cross-sectional study from a Greek tertiary center.

Background: Infliximab monitoring correlates with improved outcomes in inflammatory bowel disease (IBD). We aimed to evaluate the association between serum infliximab trough levels (TLs) and therapeutic outcomes in Greek patients with Crohn's disease (CD) or ulcerative colitis (UC).

Methods: This cross-sectional study included consecutive adult patients with IBD receiving intravenous infliximab maintenance therapy at a Greek tertiary center.

Oleuropein Promotes Neural Plasticity and Neuroprotection via PPARα-Dependent and Independent Pathways.

Oleuropein (OLE), a main constituent of olives, displays a pleiotropic beneficial dynamic in health and disease; the effects are based mainly on its antioxidant and hypolipidemic properties, and its capacity to protect the myocardium during ischemia. Furthermore, OLE activates the peroxisome proliferator-activated receptor (PPARα) in neurons and astrocytes, providing neuroprotection against noxious biological reactions that are induced following cerebral ischemia. The current study investigated the effect of OLE in the regulation of various neural plasticity indices, emphasizing the role of PPARα.

Age-related modifications in CYP-dependent drug metabolism: role of stress.

Accumulating clinical evidence indicates extensive inter-individual variations in the effectiveness and adverse effects of standard treatment protocols, which are largely attributed to the multifactorial regulation of the hepatic CYP-dependent drug metabolism that is connected with either transcriptional or post-translational modifications. Age and stress belong to the most important factors in CYP gene regulation. Alterations in neuroendocrine responses to stress, which are associated with modified hypothalamo-pituitary-adrenal axis function, usually accompany ageing.

Unraveling the role of resistin, retinol-binding protein 4 and adiponectin produced by epicardial adipose tissue in cardiac structure and function: evidence of a paracrine effect.

Purpose: Adipokines produced by adipose tissue have been found to be involved in the pathophysiology of metabolic and cardiovascular diseases. We aimed to investigate the relationships of resistin, retinol-binding protein 4 (RBP4) and adiponectin produced by epicardial adipose tissue with coronary artery disease (CAD) and cardiac structure and function.

Methods: Forty-one non-diabetic males scheduled for cardiothoracic surgery were examined.
