We report the observation of a phase of phospholipid that contains a structure similar to the commonly postulated interbilayer state that is crucial to membrane fusion. The widely accepted model for membrane fusion suggests that there is an intermediate state in which the two contacting monolayers become continuous via an hourglass-shaped structure called a stalk. Many efforts have been made to...

one of the emerging therapeutic strategies for targeted treatment of most cancers is the use of immunotoxins which are fusion proteins consisted of a targeting and a toxic moieties. we previously showed that the recombinant a254-gmcsf fusion protein selectively kills acute myeloblastic leukemia cells which harbor a large number of granulocyte-macrophage colony stimulating factor (gmcsf) recepto...

purpose t1wi (t1 weighted image) was acquired in order to grade bone fusion following the studies by fifa (federation internationale de football associations). research using images other than t1wi has not been reported. the aim of this study is to evaluate the grade of epiphyseal fusion by t2* weighted images (t2*wi) and to investigate new findings on t2*wi as compared with t1wi. methods a tot...

objective: helicobacter pylori is a widely distributed gram negative bacterium that infects the human stomach and duodenum. some antibiotic regimens are subjected to cure the infection but the cost of drugs, poor patient compliance and emerging of antibiotic-resistant strains are limiting the usefulness of these antibiotic therapies. therefore, interest in developing a h. pylori vaccine is grow...

Fusion frames are a generalized form of frames in Hilbert spaces. In the present paper we introduce Bessel subfusion sequences and subfusion frames and we investigate the relationship between their operation. Also, the definition of the orthogonal complement of subfusion frames and the definition of the completion of Bessel fusion sequences are provided and several results related with these no...

objective(s) staphylococcus aureus is a leading cause of many nosocomial and community acquired infections. according to many reports, antibiotic therapy can not guarantee the eradication of s. aureus infections. thus designing an adhesin based vaccine could restrain the s. aureus infections. this study designed for construction of a new fusion protein vaccine against s. aureus infections based...

Background: Fusion of dendritic cells (DCs) with melanoma cells could reinforce the antigenicity of tumors as a strategy for the treatment of malignant melanoma. However, the insufficient quantity of DCs and the low fusion efficiency limits the development of such approach. Objective: To define the dosage of the stimulating factors as well as the induction condition for the optimal DCs prepara...

Objective(s):Human Cytomegalovirus (HCMV) remains a major morbidity and mortality cause in immuno suppressed patients. Therefore, significant effort has been made towards the development of a vaccine. In this study, the expression of the pp65 and gB fusion peptides and Fc domain of mouse IgG2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (APCs) in Pich...
