Abstract

Spontaneously stereotyping female and male bank voles were injected daily (except on days assigned for monitoring behaviour) during 3 weeks with placebo, the neurolepticum clozapine or the SSRI antidepressant citalopram. Clozapine blocks dopamine (DA) receptors and acts as a partial serotonin (5-HT) antagonist, while citalopram is a specific 5-HT agonist. Stereotypies in both sexes were left unaffected by clozapine treatment, but citalopram markedly reduced stereotypy levels in females. Animal stereotypies have been widely used in models to provide insight into the underlying pathophysiological processes in human mental disturbances. The present findings highlight the importance of examining sex as a significant variable in evaluating responses to pharmacotherapy, and the demonstrated effect of citalopram indicates that stereotyping female bank voles may be useful in new animal models for human anxiety and mood disorders.

Abstract

The peroxiredoxin family was discovered approximately 30 years ago and is now recognized as one of the most important families of enzymes related to antioxidant defense and cellular signaling. Peroxiredoxin 6 shares the basic enzymatic functions that characterize this family, but also exhibits several unique and crucial activities. These include the ability to reduce phospholipid hydroperoxides, phospholipase A2 activity, and an acyl transferase activity that is important in phospholipid remodeling. This book describes the available models for investigating the unique functions of PRDX6 and its role in normal physiological function, as well its roles in the pathophysiology of diseases including cancer, diseases of the eye, and male fertility.

Abstract

Phospholipases are a ubiquitous group of enzymes that hydrolyze ester bonds within membrane phospholipids. These enzymes serve multiple biological functions that go far beyond a mere membrane remodeling role in cellular homeostasis; they also play key functions in nutrient digestion and the regulated formation of bioactive lipids involved in cell signaling. It is to the latter function, critical to life, that this book is primarily concerned with. All the chapters are written by renowned experts in the area, and provide forefront information on the role phospholipases in a number of physiological and pathophysiological settings.

Abstract

Dear colleagues, This Special Issue, “Endothelial Dysfunction: From Pathophysiology to Novel Therapeutic Approaches”, focuses on the pathophysiology of endothelial dysfunction, new biomarkers for endothelial dysfunction related to cardiovascular disorders or tumors, and novel therapeutic approaches for endothelial dysfunctions. Vascular endothelium is an active tissue and plays a crucial role in the maintenance of vascular homeostasis. Chronic exposure to risk factors, such as hypertension, high cholesterolemia, or oxidative stress, induces endothelial dysfunctions and results in a loss of endothelial integrity, smooth muscle cell proliferation, and macrophage recruitment. The pathophysiology of endothelial dysfunction (ED) is complex and multi-factorial factors are involved, such as oxidative stress or chronic inflammation. The primary prevention of cardiovascular risk factors and endothelial dysfunctions, as well as the early detection of or molecular imaging techniques for endothelial dysfunction, helps to prevent the development of cardiovascular disorders. Novel therapeutic approaches or drug delivery systems for endothelial dysfunctions have had promising beneficial effects in preclinical or clinical levels by affecting the progression of atherosclerotic changes, tumor angiogenesis, and host–immune reactions near tumor environments.
