[ 1 ] - مقایسه فراوانی میکروسپوریدیوزیس در نمونه های بالینی بیماران دارای نقص ایمنی و افراد سالم در تهران (1390- 1389)
زمینه و هدف: عفونت میکروسپورودیایی تقریباً در همه میزبانان بی مهره و مهره دار، از جمله انسان رخ می دهد. هدف از این مطالعه مقایسه فراوانی میکروسپوریدیوزیس با روش مولکولی در نمونه های مختلف بیماران مبتلا به نقص ایمنی با افراد سالم بود. مواد و روش ها: در این مطالعه مورد-شاهدی، 258 نمونه مدفوع و لاواژ برونکوآلوئولار (BAL) از بیماران دارای نقص ایمنی (پیوند مغز استخوان، پیوند کلیه و دارای عوارض تنفس...
[ 2 ] - بررسی ژنوتیپ های ژیاردیا دئودنالیس در بیماران بدون علامت با استفاده از ژن بتاژیاردین
Background and purpose: Giardiasis is a major diarrheal disease and the major symptoms include diarrhea, bloating, abdominal cramps, weight loss, and abdominal pain. In developing countries, some patients can carry giardia parasites without experiencing any symptoms and some genotypes are believed to be responsible for that. The aim of this study was the genotyping of giardia duodenalis in asym...
[ 3 ] - Curcumin-loaded Chitosan Tripolyphosphate Nanoparticles as a safe, natural and effective antibiotic inhibits the infection of Staphylococcus aureus and Pseudomonas aeruginosa in vivo
Background: Curcumin as a yellow natural compound extracted from turmeric root is known it as an antibacterial agent. One of the nanoparticles ability is to decrease the defects of usual drug delivery systems. Chitosan is a low toxic, biodegradable, biocompatible and safe polymer which is used in production of nanoparticles. Nanoparticles like chitosan-tripolyphosphate (TPP) are able to increas...
[ 4 ] - Effect of Cecropin–melittin Chimeric Peptide (CM11) on Trophozoite of Giardia lamblia In Vitro
Background and purpose: Antimicrobial peptides (AMP) are one of the most diverse antimicrobial compounds that have received much attention due to the development of drug resistance of pathogens to conventional antibiotics. But, few studies have evaluated anti-parasitic properties of AMP. The present study was conducted to compare the effect of a cecropin–melittin chimeric peptide (CM11) and met...
[ 5 ] - Genotyping of Acanthamoeba Species Isolated from Keratitis Patients by PCR Sequencing Methods in Tehran, Iran
Background and Aims: Amoebae of the genus Acanthamoeba are unicellular amphizoic opportunistic pathogens that may cause fatal granulomatous encephalitis, eye keratitis, amebic pneumonitis and skin nodules as well as abscesses in humans and animals. Acanthamoeba keratitis is caused by trauma to the eye, contaminated cleaning solutions and the use of contact lenses. The aim of the present study w...
