There are a number of shortcomings for currently-available technologies ammonia production, such as carbon dioxide emissions and water consumption. We simulate novel model production from hydrogen sulfide through membrane technologies. The proposed process decreases the need external reduces physical footprint plant. required comes separation by electrochemical separation, while nitrogen is obt...

Members of the SLC36 family proton-coupled amino acid transporters are involved in membrane transport acids and derivatives [29, 30]. The four show variable tissue expression patterns expressed various cell types at plasma-membrane intracellular organelles. PAT1 is luminal surface small intestine absorbs [4]. In lysosomes, functions as an efflux mechanism for produced during intralysosomal prot...

The water management is a critical problem to overcome in the PEM fuel cell technology. Models play an important role in fuel cell development since they enable the understanding of the influence of different parameters on the cell performance allowing a systematic simulation, design and optimization of fuel cells systems. In this work, a model previously developed and validated, is used to pre...

PURPOSE To establish an untransfected human corneal endothelial (HCE) cell line and characterize its biocompatibility to denuded amniotic membrane (dAM). METHODS Primary culture was initiated with a pure population of HCE cells in DMEM/F12 media (pH 7.2) containing 20% fetal bovine serum and various supplements. The established cell line was characterized by growth property, chromosome analys...

Human, rat, and mouse placentas and rat and mouse intestines were homogenized in buffered saline, and fraction consisting primarily of cell membranes was separated from each of the homogenates by differential centrifugation. Human, bovine, and guinea pig IgG, and human IgE, Bence-Jones protein, serum albumin, insulin, and growth hormone were labeled with (131)I or (125)I, and the binding of the...

Despite the fact that two thirds of all pharmaceuticals today target membrane proteins, we know rather little about them since the complexity of the cell membrane makes membrane proteins difficult to study. Furthermore, since membrane proteins control transport of molecules across cell membranes, it is also difficult to study such transportation processes. In this thesis a method for studying t...

The cell wall is one of the characteristic components of plant cells. The cell wall composition differs among cell types and is modified in response to various environmental conditions. To properly generate and modify the cell wall, many proteins are transported to the plasma membrane or extracellular space through membrane trafficking, which is one of the key protein transport mechanisms in eu...

Abstract A discrete-forcing immersed boundary method with permeable membranes is developed to investigate the effect of lubrication on permeations solute and solvent through membrane. The permeation models are incorporated into discretisation at fluid cells including membrane, discretised equations for pressure Poisson equation convection–diffusion represented discontinuities validity proposed ...

Polarized epithelial cells are distinguished from many other cell types by the presence of distinct plasma membrane domains, termed apical and basal-lateral, which face different biological compartments separated by the epithelium (Rodriguez-Boulan and Nelson, 1989). An important problem is to understand the mechanisms involved in the development of the structural and functional organization of...

Stimulation of cells with epidermal growth factor (EGF) induces internalization and partial degradation of the EGF receptor (EGFR) by the endo-lysosomal pathway. For continuous cell functioning, EGFR plasma membrane levels are maintained by transporting newly synthesized EGFRs to the cell surface. The regulation of this process is largely unknown. In this study, we find that EGF stimulation spe...
