Prevalence of anticardiolipin antibody IgM and IgG in women with recurrent abortions in Kirkuk city
Get PDFToxoplasma gondii, a parasite that can produce a wide range of clinical symptoms in humans, is the source of the zoonotic infection known as Toxoplasmosis. The goal of this study was to measure the serum levels of anticardiolipin (ACL) antibodies (ACL-IgM and ACL-IgG) in 200 women with T.gondii and recurrent abortions. Two hundred (200) blood samples from aborted women were used in this study, which was carried out in Kirkuk between November 1, 2022, and March 21, 2023, at the Gynaecological & Paediatric Hospital and Kirkuk General Hospital to determine the level of Anticardiolipin IgG and IgM serum. In this study of 200 aborted women, 28 (14%) had IgM positivity, 66 (33%) had IgG positivity, and 94 (47%) had Toxoplasmosis positivity overall. Of 200 aborted women, 39 (19.5%) had anticardiolipin IgM while 35 (17.5%) had Anticardiolipin IgG. The anticardiolipin IgM higher than anticardiolioin IgG in the Toxoplasmosis infected women
Investigation of Human Parvovirus B19 Seroprevalence among Pregnant Women Experiencing Spontaneous Abortion in Kirkuk City, Iraq
No full textHuman parvovirus B19 (HPV B19) may cross the placenta from mother to the fetus and cause major problems like non-immune hydrops fetalis, severe fetal anemia, as well as fetal mortality. The aim of the study was to determine the seroprevalence of HPVB19 in pregnant women with spontaneous abortion in kirkuk. From November 2022 to the April 2023, blood samples from 135 aborted women aged 15-45 and 45 women with successful pregnancies as a control group were taken. Using the ELISA Technique, the sera from the samples were tested for HPV B19 -specific IgM and IgG antibodies. The result showed that 13 (9.63%) tested positive for HPV B19 IgM, 28 (20.74%) tested positive for IgG,P<0.01.The highest seroprevalence of HPV B19 IgM antibodies was observed in the 15-25 age group (61.54%). HPV B19 IgG antibodies highest prevalence in the 26-35 age groups (50%) (P<0.05).The study showed that in the 1st trimester, 11 cases (84.62%) tested positive for HPV B19 IgM antibodies, while 20 cases (71.43%) tested positive for IgG antibodies.Among women with three abortions, a higher proportion tested positive for HPV B19 antibodies, with 76.92% testing positive for HPV B19IgM and 82.14% testing positive for IgG, among women residing in rural areas, a higher proportion tested positive, with 76.92% testing positive for HPV B19 IgM antibodies and 75% testing positive for HPV B19 IgG antibodies. In the normal weight category, 69.23% tested positive for HPV B19 IgM antibodies, and 82.14% tested positive for IgG antibodies. Aborted women have a higher prevalence of Parvovirus HPV B19 IgM and IgG than control groups, suggesting a potential association between B19 infection and pregnancy loss.

RF-RFE-SMOTE: A DoS And DDoS Attack Detection Framework
Get PDFDenial of service and Distributed denial of service (Dos/DDos) attacks continue to be one of the most significant dangers in cybersecurity. Many efforts are being put into developing defenses against these types of attacks. The tools used by attackers to perform these types of attacks increase day-to-day. Thus, a countermeasure is necessary. For this reason, this thesis utilized one of the most recent datasets (CSE-CICIDS2018 and CIC-DDoS2019) containing most Dos/DDoS attacks. This study proposed a framework based on Machine Learning for detecting denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks. The framework comprises three main modules: feature selection method using Random Forest—Recursive Feature Elimination (RF-RFE), handling the Imbalanced class distributions using Synthetic Minority Oversampling Technique (SMOTE), and classification. This study used five classifiers to make comparisons that include Random Forest (RF), Naive Bayes (NB), Logistic Regression (LR), and Linear and Quadratic Discriminant Analysis (LDA, QDA)”. Framework empirical findings reveal that the RF-RFE_SMOTE_RF outperformed all other models by obtaining an accuracy of 100% for CSE-CIC-IDS2018 and 0.99% for CIC-DDoS2019
