OBJECTIVES Dengue represents one of the most serious life-threatening vector-borne infectious diseases that afflicts approximately 50 million people across the globe annually. Whilst symptomatic infections are frequently reported, asymptomatic dengue remains largely unnoticed. Therefore, we sought to investigate the immune correlates conferring protection to individuals that remain clinically a...

Aspirin exacerbated respiratory disease (AERD) is characterized by chronic hyperplastic rhinosinusitis, nasal polyposis, asthma, and aspirin sensitivity. The mechanisms which produce these manifestations of intolerance are not fully defined, current research focuses on cyclooxygenase 1 (COX-1) inhibition, metabolism of arachidonic acid, and the COX pathway to the lipoxygenase (LO) route, induci...

Ribonucleic acid interference (RNAi) based on microRNA (miRNA) context may provide an efficient and safe therapeutic knockdown effect and can be driven by ribonucleic acid polymerase II (RNAP II). In this study, we designed and synthesized miR155-based artificial miRNAs against heparanase (HPSE) constructed with BLOCK-iT™ Pol II miR RNAi Expression Vector Kit. The expression levels of HPSE decl...

PURPOSE To investigate the effects of T-cell-derived cytokines on gene and protein expression of chemokines in a human RPE cell line (ARPE-19). METHODS We used an in vitro coculture system in which the RPE and CD3/CD28-activated T-cells were separated by a membrane. RPE cell expression of chemokine genes was quantified using three different types of microarrays. Protein expression was determi...

Synovial biomarkers are increasingly important in the development of novel therapeutic agents for treatment rheumatoid arthritis (RA). To identify correlating with changes clinical disease activity, real-time quantitative PCR (Q-PCR) was used to evaluate synovial gene expression after corticosteroids. Patients active RA received either oral prednisolone (n = 10, 60 mg daily first week and 40 se...

Children with healthcare-associated Clostridium difficile infection were identified. The incidence increased from 3.2/10,000 patient days in 2007 to 5.2/10,000 patient days in 2011 (p < 0.001). Of 169 isolates, the most common North American Pulsed-Field (NAP) types were NAP4 (n = 43; (25.4%), and NAP1 (n = 25;14.8%) while 55 (32.6%) were non-assigned NAP types.

to investigate the correlation between il-8 (-251 a/t) gene polymorphism and susceptibility to chronic periodontitis as well as different clinical parameters and severity of the condition in patients referred to dental school, shiraz university of medical sciences, shiraz, iran.in this randomized cross sectional study, 227 non-smoking patients with chronic periodontitis (test) and 40 healthy in...

Aim To create an irreversible pulpitis gene signature from microarray data of healthy and inflamed dental pulps, followed by a bioinformatics approach using connectivity mapping to identify therapeutic compounds that could potentially treat pulpitis. Methodology The Gene Expression Omnibus (GEO) database, international public repository genomics sets, was searched for human datasets assessing A...

OBJECTIVES Modified regular ginseng extract (MRGX) has stronger anti-cancer activity-possessing gensenoside profiles. METHODS To investigate changes in gene expression in the MRGX-treated lung cancer cells (A549), we examined genomic data with cDNA microarray results. After completing the gene-ontology-based analysis, we grouped the genes into up-and down-regulated profiles and into ontology-...
