Background: Salmonella, a bacterial genus of more than 2500 serotypes is considered as the most significant foodborne pathogen causing infections in humans and animals. Increased antimicrobial resistance and persistence of antimicrobial residues in food matrices warrants the need for alternative infection management strategies. Aims: The present study aimed to isolate and evaluate the lytic act...

helicobacter pylori is an important human pathogen and a gram-negative, spiral shaped and microaerophilic bacteria with persistence colonization in gastric mucosa, causes gastroduodenal inflammation and destruction, resulting in diseases such as duodenal ulcer disease, gastric ulcer disease. when h.pylori discovered by warren and marshall, effective therapy developed for this infection and resu...

production and approval of trastuzumab (herceptin®) for the treatment of metastatic breast cancer (mbc) was a millstone in antibody-based targeted therapy in the cancer treatment. however, despite the early success in the clinical trials, trastuzumab failed to appreciate the initial attraction due to development of resistance to the drug. the majority of patients who benefit from the drug acqui...

Objective: Resistance of metastatic lymph nodes (LNs) to high dose I-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. We evaluated the role of F-18 FDG PET/CT in the prediction of resistance to high dose I-131 therapy in patients with papillary thyroid cancer. Methods: The subjects were 307 patients who underwent total or near total thyroidectomy fol...

patients and methods in this study, 87 specimens from iranian patients were amplified using nested pcr amplification of the ul97 gene. sequence analyses of products were performed for identifying the mutated codons. results the present study show that the most frequent gcv-resistant mutations occurred in codons a594v (26.43%), h520q (18.39%), and m460v (13.79%), consequently occurring at a low ...

hepatitis c virus (hcv) envelope glycoprotein-2 (e2) inhibits the interferon (ifn)–induced, double –stranded rna activated protein kinase (pkr) via pkr eukaryotic initiation factor-2α phosphorylation homology domain (pephd). present study examined the genetic variability of the pephd in patients receiving interferon therapy. the pephd region from hcv genotype 1a/1b infected patients receiving i...

objective(s): p-glycoprotein (p-gp) is an efflux protein, the overexpression of which has been associated with multidrug resistance in various cancers. although sirna delivery to reverse p-gp expression may be promising for sensitizing of tumor cells to cytotoxic drugs, the therapeutic use of sirna requires effective carriers that can deliver sirna intracellularly with minimal toxicity on targe...
