Background: Alopecia areata(AA) is a common autoimmune disease that causes hair loss without scarring. It occurs as a result of T-helper 1 (Th1) and Th17 cells attacking the anagen hair follicles. Genetic factors play a role in the occurrence of infection, which stimulates the production of pro and anti-inflammatory interleukins. Polymorphisms of IL-37 play a role in autoimmune diseases. However, IL37 single nucleotide polymorphisms(SNP) have not been identified in patients with AA. Therefore, this study aimed to reveal the IL37 gene SNP and its relationship to AA. Methods: Genotyping of IL-37 gene single nucleotide polymorphisms SNPs were detected using sequence-specific primer-polymerase chain reaction (SSP-PCR) method was done following the protocol of DNA Extraction kit and PCR PreMix SNP Genotyping Assays in 51 (32 males & 19 females at age mean 27.90±1.66 years) patients with AA and 50 (21 males & 29 females at age mean30.64±2.08years ) healthy individuals. Results: The results of the present study showed a significant increase in the mean level of IL-37 in the serum of patients with AA compared to healthy subjects (184.18±69.45 vs.153.28±48.17) pg/ml. This increase did not constitute a significant difference at a probability level less than. In addition, genotypes of single nucleotide polymorphisms (SNPs) of IL-37 gene were rs3811045 (5756 T>C) and rs3811046 (5831 G>T) that result in substitution and inversion mutations, and thus cause a change in the type of amino acid. The CC and allele C and TC of rs3811045 were risk factors for AA due to a significantly higher odd ration (OR) value and a significantly increased frequency percentage in patients group compared to a healthy control group (37.50 vs 25.58 OR: 1.75 p = 0.264, 95% CI = 0.72–4.25, 66.0 vs 86.0 OR: 1.78 p = 0.068, 95% CI = 0.98–3.23; 56.25 vs 55.81 OR: 1.02 p = 1.0 95% CI = 0.45–2.31 respectively). Also the results of rs3811046 recorded that the TT and allele T frequency percentages were significant increase in patients group (39.58 vs 25.58 OR: 1.91 P = 0.184, 95% CI = 0.79-4.63, 66.0 vs. 52.0 OR: 1.74, P =0.072,95%CI= 0.96–3.15) respectively, which was a risk factor for infection. This study is the first of its kind to show the relationship of IL-37 level and genetic single nucleotide polymorphisms with AA. Conclusions The present study's results can conclude that the TC, CC and the C allele of IL-37 SNP rs3811045 and TT genotypes and the T allele of IL-37 SNP rs3811046 have a role in the risk of developing AA. It is recommended to conduct several genetic studies of other interleukin genes and to ascertain their relationship to AA. © 2023, Journal of Biomechanical Science and Engineering.

This bacterium has the capability to resist wide range of antibiotics and it is responsible for many diseases like skin, nose and wounds infection. In this study, randomly amplified polymorphic DNA (RAPD)-PCR was applied with ten random primers to examine the molecular diversity among methicillin resistant Staphylococcus aureus (MRSA) isolates in the hospitals and to investigate the genetic distance between them. 90 Isolates were collected from clinical specimens from Iraqi hospitals for a total of 90 isolates. Only 10 strains (11.11%) were found to be MRSA. From these 10 primers, only 9 gave clear amplification products. 91 fragment l

It is prevalent in shelters and birthplace colonies and frequently infects kitten cats. 50 distinct cats were involved in the research, with samples acquired between October 2020 and January 2021. Swabs were taken from the oropharynx and conjunctiva, conditional on the signs of FCV disease septicity, to inspect viral nucleic acid from collecting samples, then extract the RNA from the swabs and turn it into a cDNA particle, and finally distinguishing the open reading frame nucleic acid gene 2 using a primer special for feline calicivirus, All specimens were taken

This research not only reviews the problems, but it illustrates them in a philosophical way, basis of the data of modernity, this mean it is a process of connecting between the absence of the modernity values and the failure of development in underdeveloped countries. The Search follows the descriptive approach to get to the goal of search by four main axes. The first axis includes clarifying modernity and its principles, the second axis includes clarifying the economic development , the third axis includes the features of the mod

And the most important one is the climatic change and its effect on environmental, economic,
social, and political effects. So, the amount of rain which is considered as one of climatic
changes in Iraq should be studied.So, this research explains the factors which affect rain, its
overall average, the variation in the amounts of rain, the amount of yearly rain and variation
in both yearly and monthly rains by using standard variation and yearly fluctuation.As a
result, it is concluded that the number of rainy days doesn't mean an increase in rains amount.
And there's variation in rains amount in all study areas which is contrastive
The economy of a city has an important role not only in its establishment but also in its development. This is quite clear in the city of Baghdad throughout its history since its building in 762 A.D. In addition, most of its problems that the city is suffering from are basically related to not giving enough importance to the economic factors in the master planning of Baghdad since 1950’s. This may explain the failiars of master plans in dealing with the actual population growth and the city's inability to absorb such increases and interrelated and diverse activities which are negatively reflected on the economic variables particularly the effect on the land values, and the strong competitions amongst the land uses without previ
