Introduction: In the recent decades, a number of studies have highlighted the importance of Helicobacter pylori in the initiation and development of peptic ulcer and gastric cancer. Some potential virulence factors (e.g., urease, CagA, VacA, BabA) are exploited by this microorganism, facilitating its persistence through evading human defense mechanisms. Among these toxins and enzymes, vacuolating toxin A (VacA) is of a great importance in the pathogenesis of H. pylori. VacA toxin shows different pattern of cytotoxicity through binding to different cell surface receptors in various cells...

Introduction: Substrate stiffness regulates cellular behavior as cells experience different stiffness values of tissues in the body. For example, endothelial cells (ECs) covering the inner layer of blood vessels are exposed to different stiffness values due to various pathologic and physiologic conditions. Despite numerous studies, cells by time span sense mechanical properties of the substrate, but the response is not well understood. We hypothesized that time is a major determinant influencing the behavior of cells seeded on substrates of varying stiffness...

Introduction: Cancer cells are critically correlated with lipid molecules, particularly fatty acids, as structural blocks for membrane building, energy sources, and related signaling molecules. Therefore, cancer progression is in direct correlation with fatty acid metabolism. The aim of this study was to investigate the potential effects of common chemotherapeutic agents on the lipid metabolism of hepatocellular carcinoma (HCC) and colorectal cancer (CRC) cells, with a focus on alterations in cellular fatty acid contents...

Reactive oxygen species (ROS) are produced under normal physiological conditions and involved in several cellular biochemical processes. Their external or endogenous overproduction induces a disruption of redox signaling and control known as oxidative stress. Under oxidative stress, the cell membrane structures, enzyme functions and gene expression are compromised leading to the pathogenesis of several chronic inflammatory diseases including the cardiovascular pathologies. Attempts to find new therapeutic molecules capable of blocking the oxidative stress are of crucial importance...

Introduction: Desired clinical outcome of pharmacotherapy of brain diseases largely depends upon the safe drug delivery into the brain parenchyma. However, due to the robust blockade function of the blood-brain barrier (BBB), drug transport into the brain is selectively controlled by the BBB formed by brain capillary endothelial cells and supported by astrocytes and pericytes. Methods: In the current study, we have reviewed the most recent literature on the subject to provide an insight upon the role and impacts of BBB on brain drug delivery and targeting...

Introduction: The rejuvenation characteristics of fat tissue grafting has been established for many years. Recently it has been shown that stromal vascular fraction (SVF) of fat tissue contributes to its rejuvenation properties. As the SVF is a minimal processed cell population (based on FDA guidance), therefore it is a suitable cell therapy for skin rejuvenation. This clinical trial was aimed to evaluate the ultrastructural improvement of aging skin in the facial nasolabial region after transplantation of autologous SVF...
