This study describes the design and evaluation of a portable bright-field fluorescence microscope that can be manufactured for $240 USD. The uses battery-operated LED-based flashlight as light source achieves resolution 0.8 microm at 1000x magnification in mode. We tested diagnostic capability this new instrument to identify infections caused by human pathogen, Mycobacterium tuberculosis. Sixty-four direct, decontaminated, serially diluted smears were prepared from sputa obtained 19 patients...
Yeasts are alternative source of natural carotenoids, a group colored terpenoids with various market applications. Carotenoid Production by yeast fermentation technology is greatly effective and proposes considerable benefits large scale production, cost effectiveness safety. In this study, four pigment-producing yeasts were isolated from forest park soils the potential to produce carotenoids. Morphological, physiological, biochemical molecular characterization indicates isolates belong...
ABSTRACT Hydrocarbon contamination, primarily from oil spills and their derivatives, poses significant environmental challenges has profound impacts on public health ecosystems. Innovative bioremediation strategies, especially those utilizing laccase enzymes, have emerged as robust sustainable solutions to degrade these persistent pollutants. This study focused optimizing production Enterobacter sp. GR18 , isolated the Grawan mineral spring near Sardasht, West Azerbaijan Province, Iran. The...
Adipose derived stem cells ( ADSC s) and bone marrow BMSC may be equally beneficial in treating neurodegenerative diseases. However, s have practical advantages. In this study, we aimed to induce neurotrophic factors secreting human s. Then, compared the level of brain‐derived factor BDNF ) ciliary CNTF secretion from adipose marrow‐derived cells. Isolated were induced NTF )‐secreting The levels expression CTNF assessed using immunocytochemical, Real‐Time polymerase chain reaction, enzyme...

Today, transference of recombinant protein on the outer surface bacteria is deemed as a valuable process for various applications in biotechnology including preparation vaccines. In this study, Lpp-OmpA structure was used to present membrane E Haemophilus influenzae E. coli membrane. Also, designed according based non-classical secretion pathway using bioinformatics software such MEMSAT-SVM, ScrotumP and SignalP where it lacked any signal peptide at its N-terminal. Potential presentation...

Prevalence of three plasmid-mediated quinolone resistance determinant qnrA, qnrB, qnrS and extended spectrum Cephalosporins blaCMY, among eighty-five isolates Salmonella spp. collected in the community between 2008 2010 was determined by PCR. Not only qnr genes but also bla were positive twenty-four different isolates. PCR assay detected that 22 85 (25.8%) carried 1 (1.17%) harbored them contained qnrS, isolate all genes, 24 (28.2%) blaCMY 5 (5.88%) qnrA blaCMY. Antimicrobial susceptibility...
Sarcocystis is one of the most important and common protozoan parasites in world.Various species reported groups mammals, birds reptiles.In life cycle these parasite there are 2 hosts including hunted hunter.Usually, omnivores herbivores, as intermediate (hunted) carnivores, considered definitive host (hunter) this parasite.This research for first time examines contamination (microcyst) native Mazandaran province (Amol city).For purpose, randomly, 57 bird's breast muscles which include 18...
A total eighty four epidemiologically unrelated clinical isolates of Salmonella enterica serovars were subjected to antimicrobial susceptibility testing and molecular detection class 1 2 integrons. Eleven (13.1%) which resistant at least 4 groups agents considered as MDR (multidrug resistant) serovars. PCR assays detected intI1 intI2 genes in 50 (59.5%) 14 (16.7%) respectively. Emergence demonstrates that selection pressure is widespread increased distribution integron carrying gene...
Background: Listeria monocytogenes is a gram positive, facultative intracellular bacteria and it causative agent of listeriosis. Abortion one the most important side effect Nano chitosan widely used as nanomaterials considered due to its characteristics such bactericidal nontoxicity activity. The aim this study was isolation L. from pregnant women vaginal samples evaluation nanoparticles effects against them. Methods: Overall, 100 specimens were collected with without history abortion...
Abstract Diffuse large B-cell lymphoma is the most common histological subtype of non-Hodgkin’s lymphomas. It an aggressive malignancy that displays great heterogeneity in morphology, genetics, biological behavior and treatment response owing to chromatin remodeling epigenetics. Bioinformatic-based approaches were used understand possible signaling pathways three lncRNAs PVT1 , HULC HOTTIP . Furthermore, their expression levels quantitatively evaluated 100 patients before after treatment....
Aims: This research was carried out to detect the content and distribution of class 1 integrons in multidrug resistant Salmonella isolates. Materials Methods: Eighty four clinical isolates serovars were subjected molecular detection following antimicrobial susceptibility test using disk diffusion method MIC determination. Results: Eleven (13.1%) which at least 4 groups agents Original Research Article Rajaei et al.; BMRJ, 5(2): 186-193, 2015; no.BMRJ.2015.020 187 considered as MDR (multidrug...
Background: Acinetobacter baumannii is an important cause of nosocomial pneumonia in patients requiring long-term mechanical ventilation. Besides, extensively drug-resistant (XDR) strains infection intensive care unit (ICU) patients. Chronic infections A. and antimicrobial resistance are associated with biofilm formation. Several virulence genes, such as blaPER-1, pgaA, bap, involved Objectives: The current study examines the expression levels formation-related genes Methods: sputum samples...
