Autologous cell therapy represents a novel treatment option for vascular regeneration in different disease conditions. Both experimental and clinical studies indicate a therapeutic potential for different proangiogenic cells (PCs), including endothelial progenitor cells (EPCs) in the treatment of peripheral artery disease. A significant improvement of ischemic symptoms has been reported in different trials evaluating PCs for the treatment of critical limb ischemia. However, contrasting results from different meta-analyses question the efficacy of PC-based approaches on long-term outcomes, including amputation and survival...

Circulating endothelial cells (CECs), originated form endothelial progenitors (EPCs) are mature cells which are not associated with vessel walls, and that are detached from the endothelium. Normally, they are present in insignificant amounts in the peripheral blood of healthy individuals. On the other hand, elevated CECs and EPCs levels have been reported in the peripheral blood of patients with different types of cancers and some other diseases. Consequently, CECs and EPCs represent a potential biomarker in several clinical conditions involving endothelial turnover and remodeling, such as hematological diseases...

In the last four decades, the several classes of diuretics, currently available for clinical use, have been the first line option for the therapy of widespread cardiovascular and non-cardiovascular diseases. Diuretic drugs generally exhibit an overall favourable risk/benefit balance. However, they are not devoid of side effects. In particular, all the classes of diuretics cause alteration of potassium homeostasis. In recent years, understanding of the physiological role of the renal outer medullary potassium (ROMK) channels, has shown an intriguing pharmacological target for developing an innovative class of diuretic agents: the ROMK inhibitors...

Mitochondria play a central role in ATP-generating processes. Indeed, in mammalian tissues, up to 90% of ATP is generated by mitochondria through the process of oxidative phosphorylation; furthermore, mitochondria are involved in multiple signal transduction pathways. A rapidly expanding body of literature has confirmed that mitochondria play a pivotal role in apoptosis, cardio- and neuro-protection, and various neurodegenerative disorders, ranging from Parkinson's to Alzheimer's disease. It is evident that mitochondria are also the targets of multiple drugs; some of these are exactly designed to influence mitochondrial function, while others have primary targets in other cellular locations but may interact with mitochondria because of the presence of numerous targets on this organelle...

Alzheimer's disease (AD) is a public health priority all over the world. The difficulty of fighting the disease consists mostly in the complexity of symptoms and causes, in the still poor knowledge of its mechanisms and in the existence of a latent, asymptomatic, preclinical stage. Although many drugs are continuously screened in clinical studies for the treatment of Alzheimer's disease, the unexpected lack of patient response and sometimes the important adverse effects make it a potential field of application for personalized medicine...

Whether the increased atrial fibrillation (AF) risk in metabolic syndrome (MetS) patients is due to the syndrome as a whole or simply the sum of the risks of its individual component parts is still obscure. These two clinical entities share many pathophysiological links and thus distinction between a casual observation and a significant association is difficult. Biomarkers associated with pathogenesis of AF in the context of MetS have the ability to refine future risk prediction. In the present review we identify circulating substances that could be regarded as potential biomarkers for prediction of incident AF, or of cardiovascular events in the setting of AF in patients with MetS...

The majority of proteins that belong to the ATP-binding cassette (ABC) superfamily are transporters that mediate the efflux of substrates from cells. These exporters include multidrug resistance proteins of the ABCB and ABCC subfamilies, such as P-glycoprotein (Pgp) and MRP1, respectively. These proteins are not only involved in the resistance of cancer to cytotoxic agents, but also in the protection from endo and xenobiotics, and the determination of drug pharmacokinetics, as well as in the pathophysiology of a variety of disorders...

Ebola virus has caused 26 outbreaks in 10 different countries since its identification in 1976, making it one of the deadliest emerging viral pathogens. The most recent outbreak in West Africa from 2014-16 was the deadliest yet and culminated in 11,310 deaths out of 28,616 confirmed cases. Currently there are no FDA-approved therapeutics or vaccines to treat Ebola virus infections. The slow development of effective vaccines combined with the severity of past outbreaks emphasizes the need to accelerate research into understanding the virus lifecycle and the development of therapeutics for post exposure treatment...

Triterpenoids are natural compounds with a large variety of biological activities such as anticancer, antiviral, antibacterial, antifungal, antiparazitic, antiinflammatory and others. Despite their low toxicity and simple availability from the natural resources, their clinical use is still severely limited by their higher IC50 and worse pharmacological properties than in the currently used therapeutics. This fact encouraged a number of researchers to develop new terpenic derivatives more suitable for the potential clinical use...

Numerous experimental data have demonstrated that neonatal animal exposure to commonly used anesthetic agents may cause neuronal death resulting in cognitive impairment. The underlying mechanism(s) remain elusive. Depending on the circumstances, autophagy may produce an effect that can be either protective or deleterious. Recent evidence demonstrates that this process can reduce the development of ethanol induced neurotoxicity and, as we know, ethanol has γ-Aminobutyric acid (GABA) agonist and N-methyl-D-aspartate (NMDA) antagonist characteristics similar to commonly used volatile anesthetic agents...

The cutaneous route is attractive for the delivery of drugs in the treatment of a wide variety of diseases. However the stratum corneum (SC) is an effective barrier that hampers skin penetration. Within this context, liposomes emerge as a potential carrier for improving topical delivery of therapeutic agents. In this review, we aimed to discuss key aspects for the topical delivery by drug-loaded liposomes. Phospholipid type and phase transition temperature have been shown to affect liposomal topical delivery...

BACKGROUND: Bisphenol A (BPA) is an endocrine disrupting chemical widely used in the manufacture of polycarbonate plastic and epoxy resin to produce a multitude of consumer products, food and drink containers, and medical devices. BPA is similar to estradiol in structure and thus interferes in steroid signalling with different outcomes on reproductive health depending on doses, life stage, mode, and timing of exposure. In this respect, it has an emerging and controversial role as a "reproductive toxicant" capable of inducing short and long-term effects including the modulation of gene expression through epigenetic modification (i...

Caffeine is one of the most consumed stimulant of the central nervous system. Similar to those of other stimulants, its effects are to improve brain activity and stimulate cognition learning and memory. Caffeine affects the brain by acting mainly as a non-selective blocker of the adenosine receptors (A1, A2A, A2B, and A3). The purpose of this review article is to provide an overview on the neurobiochemical impact of caffeine, focusing on the ability of the drug to effectively counteract several neurodegenerative disorders such as Alzheimer's, Parkinson's, Huntington's diseases, Multiple sclerosis and Amyotrophic lateral sclerosis and Epilepsy...

BACKGROUND: Type-2 diabetes mellitus accounts for 80-90% of diabetic patients. So far, the treatment of diabetes mainly aims at elevating insulin level and lowering glucose level in the peripheral blood and mitigating insulin resistance. Physiologically, insulin secretion from pancreatic β cells is delicately regulated. Thus, how insulin-related therapies could titrate blood glucose appropriately and avoid the occurrence of hypoglycemia remains an important issue for decades. Similar question is addressed on how to attenuate vascular complication in diabetic subjects...
