Association of interleukin-6 level and DNA polymorphism in type 2 diabetic patients in Kirkuk city

The basic inflammatory factor interleukin-6 plays an important role in the inflammatory response. It has been shown that IL-6 has a role in insulin resistance and T2DM. The IL-6 gene is found on chromosome 7p15-p21 in humans, it works via a receptor composed of two components, the IL-6 receptor, and gp130. Single nucleotide polymorphisms in the regulatory areas of IL-6R genes influence their expression levels and are linked to a higher risk of T2DM. There were 80 T2DM patients and 80 healthy people enrolled in the present work. Fasting blood glucose levels, HbA1C, and IL-6 concentrations were estimated in both groups. The allelic frequencies of 2 single nucleotide polymorphisms (rs2229238, rs4845625) were identified by PCR-SSP. In this study, we found that the fasting blood sugar levels, HbA1c, and IL-6 levels were statistically highly significant in patients in comparison with controls. In regarding the association of genotypic (CC, CT, TT) and allelic frequencies of rs2229238, and rs4845625 polymorphism of the gene IL6R, and prevalence of diabetes mellitus. The results of PCR-SPP products of rs2229238 (C/T) of the IL6R gene indicated the significant correlation the rs4845625 IL6R polymorphism with T2DM, where no significant association was observed between these genotypes (CC, CT, TT) and allelic (T) frequencies of rs2229238 as a risk factor and T2D

Molecular detection of Toxoplasma gondii specific repeat element in blood of recurrent aborted women by real-time PCR

Toxoplasmosis caused by ingestion of raw or undercooked meat contains tissue cyst or contaminated food or water with oocyst of Toxoplasma gondii. This parasite is prevalent in humans, domestic and wild animals and is causative agent of abortion and congenital abnormalities. Methods: From october-2019 to April 2020, blood and serum samples were collected from 63 women with recurrent abortion. Serum samples were used for identification of anti-Toxoplasma IgM and IgG antibodies by ELISA technique. Real time- Polymerase Chain reaction technique utilized for revealing of the DNA of Toxoplasma gondii in the blood specimens. Presented study results showed the high aborted women 33 (52%) in age group (20-29), and high number of aborted women 36 (57%) have 3-6 abortions. Serodiagnosis results of 63 aborted women showed that 19 (30%) were seropositive for only IgG antibody, 6(10%) were seropositive for IgM antibody, and 6 (10%) were positive for both IgG and IgM antibodies. Molecular diagnosis of T. gondii DNA infection by RT- PCR for amplification of repeat region 529 bp of T. gondii DNA, revealed that only 7 (11.1%) blood samples were positive. RT-PCR assay was more sensitive and specific than serologic ELISA method in diagnosis of Toxoplasma gondii infection in recurrent aborted women
