Background: The genetic polymorphisms of vitamin D receptor (VDR) have an association with thalassemia development, additionally to the environmental elements that elicited the disorder in the genetically predisposed individuals. As well, VDR functions responsible for the regulation of bone metabolism, such its part in immunity. Aim: The sitting study intended to inspect the association between thalassemia disease and the genetic polymorphisms of VDR among the Iraqi population then compared these findings to other findings of thalassemia patients in other different ethnic populations. Materials and methods: The restriction enzymes Bsm-I and Fok-I were applied to determine the genetic polymorphisms frequencies of VDR by a Polymerase Chain Reaction – Random Fragment Length Polymorphisms (PCR-RFLP) techniques of the targeted parts (rs2228570 and rs1544410) in 70 Iraqi patients suffering from thalassemia (18 males and 52 females) and 75 Iraqi healthy participants as a control group (18 males and 52 females). Also, the comparison between the present findings of VDR genetic polymorphisms in Iraqi thalassemia patients and other previous findings for thalassemia patients in different ethnic populations for the selected VDR Bsm-I and Fok-I sites were done. Results: The present findings manifested a significant difference of VDR Bsm-I and Fok-I genetic polymorphisms frequency (rs2228570 and rs1544410) in the thalassemia patient's group contrasted to the healthy control group. In VDR rs2228570, the AA genotype and A allele frequency were significantly increased in the patients' group contrasted to the healthy control group (44.29 vs. 8.0%, OR: 9.14, 95% CI: 3.53–23.68, p: 4.1 × 10−7; 69.0 vs. 27.0%, OR: 6.02, 95% CI: 3.27–11.06, p: 3.9 × 10−9, respectively). while, the results of VDR genetic polymorphisms rs1544410 manifested that the CC and CT genotyping and C allele frequency were significantly increased among the patient's group contrasted to the healthy control group (28.75 vs. 6.67%, OR: 5.60, 95% CI: 1.98–15.81, p: 7.2 × 10−4; 57.14 vs. 24.0, OR: 4.22, 95% CI: 2.08–8.55, p: 8.1 × 10−5; and 57.0 vs. 19.0%, OR: 6.39, 95% CI: 3.0–10.66, p: 3.9 × 10−9, respectively). Also, it manifested the genetic polymorphisms variance of VDR rs2228570 and rs1544410 between the Iraqi thalassemia patients and other ethnic thalassemia patients. The results showed different variants among the Iraqi thalassemia patients' polymorphisms and other ethnic thalassemia patients' polymorphisms. Conclusions: The present results demonstrated a significant association between the genetic polymorphisms of VDR and thalassemia disease, the AA genotype and A allele frequency was significantly increased among the thalassemia patients' group compared to the controls in VDR Bsm-I polymorphism (rs2228570). While the CC and CT genotypes and C allele frequency were significantly increased among the thalassemia patients' group compared to the controls in VDR Fok-I polymorphism (rs1544410). As well, it indicates the variance of VDR Bsm-I and Fok-I genetic polymorphisms frequencies between the Iraqi thalassemia patients and other thalassemia patients from different ethnic populations.
Objective This study aimed to evaluate the effects of disinfectant solutions, namely, the alcoholic extract of Salvadora persica L. (A1 = 10% and A2 = 15%) and chlorhexidine digluconate (A3 = 2%), on the tear strength and hardness of room temperature vulcanizing (RTV) VST50F and heat temperature vulcanizing (HTV) Cosmesil M511 silicone elastomers before and after reinforcement with nanofillers (TiO2) and intrinsic pigment. Materials and Methods: A total of 320 specimens were prepared, with 160 specimens each for RTV and HTV silicone. Forty specimens were evaluated before disinfection and divided into two equal groups, namely, control (without additive) and experimental (with ad
The current study aimed to use some bacterial isolates from the local soil of Baghdad city by study the effects of temperature, pH and incubation period on the growth rates of isolated bacteria and choose the optimal conditions for their diversity and for understanding bacterial growth and their requirements for survival and proliferation. This information can be applied to obtain their high growth rate for use in various fields such as agriculture, medicine and environmental sciences in the future. And it used to assess the degree of variation in across bacteria species in pH, temperature and incubation period. A number of local bacterial isolates as
Objectives: This study explored knowledge, attitude, and practice of infection control by dental students at College of Dentistry/ University of Baghdad, Iraq. Material and Methods: Three hundred dental students participated in this study. A self administrated questionnaire with 21 close ended questions related to use of personal protective equipments, infection control awareness, vaccination status, percutaneous exposures, and attitude towards treatment of patients with hepatitis B (HBV)/ or human immunodeficiency virus (HIV) was distributed to dental students. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 21. Fisher exact and Chi-square test were used with significance level set to 0.05. Results: The

Pulsed Laser Deposition PLD was used to deposit thin films of different doping ratio In2O3 : SnO2 ( 0, 1, 3, 5, 7 and 9 % wt.) on glass substrate at ambient temperature under vacuum of 10 -3 bar thickness of ~100nm. The structural type ,grain size and morphology of the prepared alloys compounds and thin films were examined using X-ray diffraction and atomic force microscopy . The results showed that all alloys have polycrystalline structures and the peaks belonged to the preferred plane for crystal growth were identical with the ITO (Indium – Tin –Oxide) standard cards also another peaks were ob

Structural, morphological, and compositional characterizations of MnCo₂O₄ thin films were performed using XRD, FE-SEM, EDS, and AFM. It was found through XRD patterns that MnCo₂O₄ was formed in a cubic spinel structure for both methods; however, the chemically precipitated thin films possessed better crystallinity and larger crystallite sizes, whereas the green-synthesized films exhibited slightly lower crystallinities and smaller sizes, as evidenced by the broader peaks observed. In addition, FE-SEM and AFM images revealed that the MnCo₂O₄ films prepared by
... Show MoreAcute Respiratory Distress Syndrome (ARDS) is triggered by a variety of insults, such as bacterial and viral infections, including SARS-CoV-2, leading to high mortality. In the murine model of ARDS induced by Staphylococcal enterotoxin-B (SEB), our previous studies showed that while SEB triggered 100% mortality, treatment with Resveratrol (RES) completely prevented such mortality by attenuating inflammation in the lungs. In the current study, we investigated the metabolic profile of SEB-activated immune cells in the lungs following treatment with RES. RES-treated mice had higher expression of miR-100 in the lung mononuclear cells (MNCs), which targeted mTOR, leading to its decreased expression. Also, Single-cell RNA-seq (scRNA seq)
... Show MoreIn this research, the Williamson-Hall method and of size-strain plot method was employed to analyze X- ray lines for evaluating the crystallite size and lattice strain and of cadmium oxide nanoparticles. the crystallite size value is (15.2 nm) and (93.1 nm) and lattice strain (4.2 x10−4 ) and (21x10−4) respectively. Also, other methods have been employed to evaluate the crystallite size. The current methods are (Sherrer and modified Sherrer methods ) and their results are (14.8 nm) and (13.9nm) respectively. Each method of analysis has a different result because the alteration in the crystallite size and lattice strain calculated according to the Williamson-Hall and size-strain plot methods shows that the non-uniform strain in nan
