S-palmitoylation is a reversible, enzymatic posttranslational modification of proteins in which palmitoyl chain is attached to a cysteine residue via a thioester linkage. S-palmitoylation determines the functioning of proteins by affecting their association with membranes, compartmentalization in membrane domains, trafficking, and stability. In this review, we focus on S-palmitoylation of prote...

gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. this study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. enriched and specific media used for isolation of bacteria. identification of isola...

Ozone is a strong oxidant and disinfectant that has anti-pathogenic effect on bacteria, fungi, parasites, viruses. Because of its high reactivity, permeability, low residue, other advantages, the application ozone gaining more attention, been widely used in water treatment, equipment disinfection, public scene fields. The purpose this review to discuss use technology for animal plant protection...

BACKGROUND Black elderberries (Sambucus nigra L.) are well known as supportive agents against common cold and influenza. It is further known that bacterial super-infection during an influenza virus (IV) infection can lead to severe pneumonia. We have analyzed a standardized elderberry extract (Rubini, BerryPharma AG) for its antimicrobial and antiviral activity using the microtitre broth micro-...

background and objective: considering the increasing tendency of public towards green consumption and the dangers of artificial additives, this study aimed to assess antibacterial activity of essential oils of cinnamomum zeylanicum, mentha piperita l., zataria multiflora boiss and thymus vulgaris against three important pathogenic and spoilage bacteria (pseudomonas fluorescens, erwinia carotovo...

conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...

The purpose of this study is to produce selenium labeled peptides and phage (bacterial viruses) that can selectively bind to the surface of the pathogenic bacteria Yersinia pestis (the plague) and inactivate it through the generation of superoxide radicals on its surface, similar to the way that it is inactivated by superoxide in macrophage. The results show that phage specific for a given bact...

background and aim: for rapid growing drug resistance among pathogenic microorganisms, it is essential to find new compounds with antimicrobial activity. medicinal herbs application in traditional treatment for thousand years, make this natural compound to the best choice for antimicrobial studies. the aim of this study is to determine the antimicrobial activity of artemisia against some import...
