Mesenchymal stem cells (MSCs) are an appealing potential therapy for vascular diseases; however, many challenges remain in their clinical translation. While the use of biochemical, pharmacological, and substrate-mediated treatments to condition MSCs has been subjected to intense investigation, there has been far less exploration of using these treatments in combination with applied mechanical force for conditioning MSCs toward vascular phenotypes. This review summarizes the current understanding of the use of applied mechanical forces to differentiate MSCs into vascular cells and enhance their therapeutic potential for cardiovascular disease...

Heat shock proteins (Hsps) are ubiquitously expressed chaperone proteins that enable cells to cope with environmental stresses that cause misfolding and denaturation of proteins. With aging this protein quality control machinery becomes less effective, reducing the ability of cells to cope with damaging environmental stresses and disease-causing mutations. In neurodegenerative disorders such as Amyotrophic Lateral Sclerosis (ALS), such mutations are known to result in protein misfolding, which in turn results in the formation of intracellular aggregates cellular dysfunction and eventual neuronal death...

Retinal gene therapy has come a long way in the last few decades and the development and improvement of new gene delivery technologies has been exponential. The recent promising results from the first clinical trials for inherited retinal degeneration due to mutations in RPE65 have provided a major breakthrough in the field and have helped cement the use of recombinant adeno-associated viruses (AAV) as the major tool for retinal gene supplementation. One of the key problems of AAV however, is its limited capacity for packaging genomic information to a maximum of around 4...

Human pluripotent stem cell (hPSC)-derived mesencephalic dopaminergic (mesDA) neurons can relieve motor deficits in animal models of Parkinson's disease (PD). Clinical translation of differentiation protocols requires standardization of production procedures, and surface-marker-based cell sorting is considered instrumental for reproducible generation of defined cell products. Here, we demonstrate that integrin-associated protein (IAP) is a cell surface marker suitable for enrichment of hPSC-derived mesDA progenitor cells...

INTRODUCTION: Spondyloarthropathies (SpA) are disabling diseases with a prevalence of 1.9% in the general population. The indices designed for monitoring the disease should be valid, reliable and cross-culturally adapted for decision-making concerning the appropriate treatment. Changing an adjective or pronoun in a self-administered questionnaire could be the big difference in condensing an idea in a few words and transmitting that concept to all those who share the same language. OBJECTIVES: To develop a Venezuelan version of the original English version of the BASDAI/BASFI and to evaluate its reliability and validity in Venezuelan patients with SpA...

High-resolution vessel wall MRI (vwMRI) of the intracranial arteries is an emerging diagnostic imaging technique with the goal of evaluating vascular pathology. vwMRI sequences have high spatial resolution and directly image the vessel wall by suppressing blood signal. With vwMRI, it is possible to identify distinct morphologic and enhancement patterns of atherosclerosis that can provide important information about stroke etiology and recurrence risk. We present a review of vwMRI research in relation to intracranial atherosclerosis, with a focus on the relationship between ischemic stroke and atherosclerotic plaque T1 post-contrast enhancement or plaque/vessel wall morphology...

Nanotechnology-based strategies can dramatically impact the treatment, prevention and diagnosis of a wide range of diseases. Despite the unprecedented success achieved with the use of nanomaterials to address unmet biomedical needs and their particular suitability for the effective application of a personalized medicine, the clinical translation of those nanoparticulate systems has still been impaired by the limited understanding on their interaction with complex biological systems. As a result, unexpected effects due to unpredicted interactions at biomaterial and biological interfaces have been underlying the biosafety concerns raised by the use of nanomaterials...

Recent advances in laboratory and clinical research have greatly enhanced our understanding of placebo effects. However, little progress has been made in translational research that can well integrate these findings. This article examines pivotal role of placebo administration in subsequent placebo responses, providing a unified framework that accounts for robust placebo effects in both laboratory and clinical settings.

Dominant optic atrophy (DOA) and Leber hereditary optic neuropathy (LHON) are the two most common inherited optic neuropathies encountered in clinical practice. This review provides a summary of recent advances in the understanding of the clinical manifestations, current treatments, and ongoing clinical trials of these two optic neuropathies. Substantial progress has been made in the understanding of the clinical, genetic, and pathophysiological basis of DOA and LHON. Pathogenic OPA1 gene mutations in DOA and 3 primary mutations of mitochondrial DNA in LHON-induced mitochondrial dysfunction, which in turn leads to increased reactive oxygen species levels in mitochondria and possibly insufficient ATP production...

Macrolides are clinically important antibiotics that inhibit protein biosynthesis on ribosomes by binding to ribosomal tunnel. Tylosin belongs to the group of 16-membered macrolides. It is a potent inhibitor of translation whose activity is largely due to reversible covalent binding of its aldehyde group with the base of A2062 in 23S ribosomal RNA. It is known that the conversion of the aldehyde group of tylosin to methyl or carbinol groups dramatically reduces its inhibitory activity. However, earlier we obtained several derivatives of tylosin having comparable activity in spite of the fact that the aldehyde group of tylosin in these compounds was substituted with an amino acid or a peptide residue...
