background : amelogenins are the major components of enamel matrix proteins. enamel matrix derivatives (emd) can be used in periodontal diseases to regenerate periodontal tissues. the main aim of this study was to evaluate ex-pression of full-length functional recombinant human amelogenin (rham) in iranian lizard leishmania (i.l.l.) as an alternative eukaryotic expression system. methods : huma...

Regarding high potential of green plants for development of recombinant vaccines, this research was conducted to evaluate expression of a novel recombinant vaccines against Foot and Mouth Disease (FMDV) in tobacco plant. For this purpose, a synthetic gene encoding 129-169 amino acids of foot and mouth disease virus capsid protein VP1 was transferred to tobacco plant via Agrobacterium-mediated g...

BACKGROUND Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen worldwide. Early detection and treatment of C.trachomatis genital infection prevent serious reproductive complications. OBJECTIVE Performances of enzyme immunoassay (EIA) and major outer membrane protein (MOMP)-polymerase chain reaction (PCR) for diagnosis of genital C.trachomatis infection in women we...

A multitarget real-time PCR (MRT-PCR) for detection of Chlamydia trachomatis DNA was developed and validated. There were three targets for amplification in a single reaction: the cryptic plasmid (CP), the major outer membrane protein (MOMP) gene, and an internal control. The assay had the following characteristics: (i) detection and confirmation of the presence of C. trachomatis DNA in a single...

objective: helicobacter pylori is a spiral, microaerophilic gram negative bacterium, that multiplies and causes infection in human gastric mucosal layer. h.pylori infection, followed by destruction of gastric epithelial tissue, leads to gastric chronic inflammation, which can cause gastric and peptic ulcers. new approaches have focused on using specific treatments, such as immunotherapy, to era...

In mammalian cells, the mitochondrial pathway of apoptosis plays a key role in various biological processes and has been extensively studied. One of the signature features of this pathway is permeabilization of the outer mitochondrial membrane (MOMP) and thus release of cytochrome c into the cytoplasm to trigger subsequent activation of executioner caspases. Because MOMP is associated with loss...

Title of Dissertation: CERAMIDE CHANNELS AND THE INDUCTION OF APOPTOSIS: STRUCTURAL INSIGHTS ON CHANNEL FORMATION AND REGULATION BY BCL-2 FAMILY PROTEINS. Meenu Nadisha Perera, Doctor of Philosophy, 2012 Directed by: Professor Marco Colombini Department of Biology A critical event in apoptosis is the release of intermembrane space proteins from mitochondria following mitochondrial outer membran...

Background: Rabies virus (RABV) is a deadly neurotropic virus that causes the disease of rabies in humans and animals. L protein is one of the large structural protein of rabies virus, which displays multiple enzymatic activities, and is required for viral transcription and replication. Objectives: A truncated L protein of Rabies virus is being cloned, expressed and purified to produce relevant...
