Long Non-coding RNA Genes Polymorphisms H19 (rs2251375) and MALAT1 (rs3200401) Association with Rheumatoid Arthritis and Their Correlation with Disease Activity in a Cohort of Egyptian Patients: A Pilot Study.

Rheumatoid arthritis (RA) is a chronic, progressive, inflammatory, autoimmune disease that could be disabling throughout its course. It affects people in their most reproductive years with relatively high morbidity and mortality. Long non-coding RNAs became one of the epigenetic mechanisms to prove a link to RA pathogenesis and development, including H19 and MALAT1 genes.

Relative CTLA-4, PTPN-22, and interleukin 37 mRNA expressions in patients with lupus nephritis.

Objectives: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by T-cell immune-dysregulation and loss of tolerance to self-antigens. CTLA-4 and PTPN-22 are involved in the inhibition of T-lymphocytes activation. IL-37 is an anti-inflammatory cytokine that suppresses innate immunity.

Assessment of Angiopoietin-2 Single Nucleotide Polymorphism in Patients with Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that destroys joint cartilage and causes disability. Synovial inflammation, with angiogenesis, is an early event in the progression of the disease. Angiopoietin 2 (ANGPT2) is a cytokine with both inflammatory and angiogenic effects.

The Association of 1064 C/T Rs3020221 Gene Polymorphism with Knee Osteoarthritis.

Osteoarthritis (OA) is a common type of arthritis, affecting millions of people around the world. Angiopoietin-2 (Angpt-2) has a role in the development of chronic inflammatory diseases. We aimed to assess the serum Angpt-2 levels in knee OA patients and to investigate the association of gene polymorphism(rs3020221 C/T) with knee OA susceptibility and severity.

Interleukin 16 polymorphism and susceptibility of rheumatoid arthritis disease in Egyptian population.

Rheumatoid arthritis (RA) is a systemic and multiple-stage disorder characterized by chronic inflammation with extensive synovitis. The genetic and environmental factors are associated with the risk for RA development. In RA, the induced IL-16 may play a role in initiating, sustaining and increasing the inflammatory response and development of synovitis, nevertheless IL-16's actual role in RA pathogenesis must be studied further.

Biochemical Analysis of C-X-C Motif Chemokine Ligand 10 (CXCL10) as a Biomarker in Patients with Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is characterized by chronic inflammation and synovial hyperplasia that eventually leads to the destruction of the joints. CXCL10 has been originally identified as a pro-inflammatory chemokine that mediate leukocyte trafficking and modulate innate and adaptive immune responses. It plays a critical role in the inflammatory response and is involved in several biological processes.

Impact of chronic schistosomiasis and HBV/HCV co-infection on the liver: current perspectives.

Schistosomiasis is a public health problem in many countries. Its prevalence is increasing annually; the current infection rate is one in 30 individuals. The WHO reported that at least 206.

25-hydroxyvitamin D Deficiency and Predictive Factors in Patients with Diabetic Nephropathy in Type 2 Diabetes Mellitus.

Diabetes mellitus is a metabolic disease that is characterized by chronic hyperglycemia. Type 2 diabetes is a global health problem and leading to many dangerous complications. Diabetic nephropathy is a significant microvascular complication resulting from diabetes mellitus that is affecting up to 50% of patients with end stage renal disease.

The association of CD40 polymorphism (rs1883832C/T) and soluble CD40 with the risk of systemic lupus erythematosus among Egyptian patients.

Background: Systemic lupus erythematosus (SLE) is a complex autoimmune disorder of unknown etiology. Considerable evidence supports a genetic basis for susceptibility to SLE. Genetic and functional data suggested the CD40 receptor (CD40) and CD40 ligand (CD40L) as strong candidate genes for SLE.

CD5+ B lymphocytes in systemic lupus erythematosus patients: relation to disease activity.

B cells are essential players in the pathogenic mechanisms of systemic lupus erythematosus (SLE). Although CD5+ B cells have been considered to play a paradoxical role in preventing, rather than inducing autoimmunity, there is no consensus agreement about the proportions of CD5+ B cells population in SLE patients. So, the aim of the present study was to assess blood concentration of CD5+ B cells in patients with SLE and to evaluate their relationship with disease activity and organ damage.

Serum Interleukin-37: a new player in Lupus Nephritis?

Introduction: Interleukin-37 (IL-37) has been proved to be a fundamental natural suppressor of innate immunity and inflammatory responses in autoimmune diseases such as systemic lupus erythematous (SLE). The purpose of this study was to assess serum IL-37 level in SLE patients and its correlation with disease activity and clinical and laboratory manifestations of SLE patients.

Patients/methods: The serum level of IL-37 was assessed and analyzed in 100 SLE patients and 50 healthy controls by using enzyme-linked immunosorbent assay (ELISA).

Impact of schistosomiasis on increase incidence of occult hepatitis B in chronic hepatitis C patients in Egypt.

Co-infection of schistosomiasis, HBV and HCV is common in countries where schistosomiasis is endemic. Occult hepatitis B occurs in patients at high risk for HBV infection (e.g.

Algal decolorization and degradation of monoazo and diazo dyes.

This study is to inspect how the variation of molecular structures and functional groups present in our models, monoazo dye (Tartrazine) and diazo dye (Ponceau), affects decolorization capabilities of green algae, cyanobacteria and diatoms. The results revealed that the removal of azo dyes was rapid at the initial period of study (3 days) and became slowly with the time (6 days). The maximum decolorization was observed at 5 ppm Tartrazine with S.

Biosorption of copper, nickel and manganese using non-living biomass of marine alga, Ulva lactuca.

The adsorption of Cu2+, Ni2+ and Mn2+ onto the marine algal biomass of Ulva lactuca was investigated in single and multimetal solutions. This study was intended to determine the role of different pH values (2-8) on the biosorption of metals at different concentrations (10, 20 and 30 mg L(-1)). The biosorption capacity of Cu2+, Ni2+ and Mn2+ for 10 mg L(-1) was the same as 20 and 30 mg L(-1), increase with increasing pH up to pH 5.

Identification of a platyhelminth neuropeptide receptor.

We report the characterisation of the first neuropeptide receptor from the phylum Platyhelminthes, an early-diverging phylum which includes a number of important human and veterinary parasites. The G protein-coupled receptor (GPCR) was identified from the model flatworm Girardia tigrina (Tricladida: Dugesiidae) based on the presence of motifs widely conserved amongst GPCRs. In two different assays utilising heterologous expression in Chinese hamster ovary cells, the Girardia GPCR was most potently activated by neuropeptides from the FMRFamide-like peptide class.
