Luminal calcium regulates vesicle transport early in the secretory pathway. In ER-to-Golgi transport, depletion of luminal calcium leads to significantly reduced transport and a buildup of budding and newly budded COPII vesicles and vesicle proteins. Effects of luminal calcium on transport may be mediated by cytoplasmic calcium sensors near ER exits sites (ERES). The penta-EF-hand (PEF) protein...

during last two decades, polysaccharides such as alginate (alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. the aim of the present work was to investigate the potential utility of microparticles made of alginate (alg) as new vehicles for improving nasal vaccine delivery. for this purpose, diphtheria toxoid (dt) was chosen as a model anti...

OBJECTIVES/HYPOTHESIS The purpose of this study was to investigate the regenerative efficacy of an injectable hyaluronic acid/mildly cross-linked alginate hydrogel (HA/ALG hydrogel) containing human adipose-derived mesenchymal stem cells (hAdMSCs) for vocal fold (VF) wound healing. STUDY DESIGN Animal research. METHODS HA/ALG hydrogel containing hAdMSCs was injected into the VFs of rabbits ...

The purpose of measures in algorithm theory is to distinguish between “good” and “bad” algorithms. The main drawback of classical worst-case analysis is that one single “bad” instance decides the performance of an algorithm. Moreover, worst-case instances are often quite artificial and often do not represent a “realistic” or “typical” instance of a problem. In this thesis, we are concerned with...

Leishmania antigens are weak immunogens and need to be potentiated by various adjuvants and delivery systems. Alginate microspheres as antigen delivery system and Quillaja saponins (QS) as immunoadjuvant have been used to enhance the immune response against Autoclaved Leishmania major (ALM). Microspheres were prepared by an emulsification technique and characterized for size, encapsulation effi...

Alix [ALG-2 (apoptosis-linked gene 2)-interacting protein X] was originally identified as a protein that interacts with ALG-2, a member of the penta-EF-hand Ca(2+)-binding protein family. ALG-2 binds to its C-terminal proline-rich region that contains four tandem repeats of PXY (where X represents an uncharged amino acid). Recent X-ray crystal structural analyses of the Ca(2+)-free and Ca(2+)-b...

BACKGROUND The therapeutic efficacy of horse antilymphocyte globulins (ALG) or of rabbit antithymocyte globulins (ATG), used for both the prevention and treatment of allograft rejection has been well documented. However, clinical use of these heterologous antibodies can result in the production of antibodies against horse or rabbit proteins and in the development of serum sickness via circulati...

This paper describes preparation and characterization of beads of alginate and psyllium containing probiotic bacteria of Lactobacillus acidophilus DMSZ20079. Twelve different formulations containing alginate (ALG) and alginate-psyllium (ALG-PSL) were prepared using extrusion technique. The prepared beads were characterized in terms of size, morphology and surface properties, encapsulation effic...

background and objectives: treatment of pseudomonas aeruginosa infections is greatly hampered by innate and acquired antibiotic resistance. the goal of this study was to compure the immunogenicity of conjugates of p. aeruginosa depolymerized alginate-diphtheria toxoid (d-algdt) and p. aeruginosa detoxified lipopolysaccharidediphtheria toxoid (d-lpsdt) in mouse model. materials and methods: algi...

ALG-2 (gene name: PDCD6) is a penta-EF-hand Ca(2+)-binding protein and interacts with a variety of proteins in a Ca(2+)-dependent fashion. ALG-2 recognizes different types of identified motifs in Pro-rich regions by using different hydrophobic pockets, but other unknown modes of binding are also used for non-Pro-rich proteins. Most ALG-2-interacting proteins associate directly or indirectly wit...
