Gram-positive bacteria are formidable human pathogens. Staphylococci are responsible for more than a million hospital-acquired bacterial infections every year. Streptococcus pneumoniae is responsible for a major portion of 3 million deaths worldwide of children from pneumonia and meningitis and for a large number of deaths from pneumonia that occurs in elderly individuals. In addition, individu...
Antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. The presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. Because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...
Nanotechnology has tremendous potential for the management of infectious diseases caused by multi-drug resistant bacteria, through the development of newer antibacterial materials and efficient modes of antibiotic delivery. Calcium phosphate (CaP) bioceramics are commonly used as bone substitutes due to their similarity to bone mineral and are widely researched upon for the treatment of bone in...
background: despite the discovery of numerous antibiotics, drug resistance still remains as a major problem. therefore, it is important to introduce and replace new sources of drug such as medicinal plants with antimicrobial properties. objective: the genus clematis (ranunculaceae family) has six species in iran. aerial parts of clematis have been used to cure fever and chronic diseases such as...
Objective(s): Polymeric nanofiber has a huge potential for a various biomedical applications such as wound healing and orthopedic implant. Since most of the future applications of therapeutic nanofiber are interacting with human blood components, it is important to investigate hemocompatibility. Methods: In this study, nanofibers with antibacterial properties were synthesizedby elec...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
background: the presence of antibacterial drug residues in food caused many concerns for consumers. this study was designed to determine of antibacterial drug residues in commercial eggs distributed in urmia, iran. methods: disc diffusion microbial inhibition test was performed using three media seeded with bacillus subtilis at different ph values (6, 7.2 or 8) and a fourth medium seeded with ...
Drug-resistant bacterial pathogens pose an urgent public-health crisis. Here, we report the discovery, from microbial-extract screening, of a nucleoside-analog inhibitor that inhibits bacterial RNA polymerase (RNAP) and exhibits antibacterial activity against drug-resistant bacterial pathogens: pseudouridimycin (PUM). PUM is a natural product comprising a formamidinylated, N-hydroxylated Gly-Gl...
