Brain injuries that caused by strokes (result of intra partum ischemia) are a frequent cause of prenatal mortality and morbidity with limited therapeutic options. Transplanting human mesenchymal stem cells (hmscs) indicates improvement in hypoxic Ischemic brain injury (HIBD) by secretion growth factor stimulating repair processes (Hmscs) known as multi potent cells which isolated from bone marr...

Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...

Introduction Perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane ...

Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

Objective(s): This study was designed to indicate whether different fractions from Artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (DOX) in rat pheochromocytoma cell line (PC12). Material and Methods:Cell viability was determined by MTT assay. Also, activation of caspase-3 and superoxide dismutase were evaluated...

Background: Type-I diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. TNF-related apoptosis-inducing ligand (TRAIL) is a type-II membrane protein of the TNF superfamily which is expressed in different tissues, including pancreas and lymphocytes. In humans, TRAIL interacts with four membrane receptors. TRAIL-R1 and TRAIL-R2...

Proton exchange membrane fuel cells (PEMFCs) with a dead-ended anode and cathode can obtain high hydrogen and oxygen utilization by a comparatively simple system. Nevertheless, the accumulation of the water in the anode and cathode channels might cause a local fuel starvation degrading the performance and durability of PEMFCs. In this study, a brand new design for a polymer electrolyte membrane...

cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injuries fallowing by car accidents. induced functional neurons are an option for replacing the lost neurons. the ability to monitor changes in membrane potential is a useful tool for studying neuronal function, but there are only limited options available at present. here, investiga...

introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...
