    Background:  Adolescent pregnancy is associated with major health consequences for adolescent pregnant women including medications and oral health problems such as dental caries and periodontal disease. Pregnancy is a unique state of physical, hormonal, and metabolic changes that can result in an oral cavity imbalance. Changes in salivary components and a decrease in salivary flow rate caused by an increase in progesterone may compromise saliva's protective effects, resulting in dental caries. Objectives: To evaluate dental caries experience in adolescent pregnancy. Method: A sample including 80 pregnant ladies were recruited in this study and categorized into a study group involving 40 primigravida adolescent females aged (15-19)years old and a control group involving 40 primigravida women (20-32) years old who married at age 20 years or more, all of them in the second trimester of pregnancy. Unstimulated salivary samples were collected, salivary flow rate, pH, and dental caries experience were assessed. Saliva samples were analyzed to estimate salivary lactoferrin concentration. Results: The mean (±sd) of decayed surface of the study group was (11.850±0.669) compared to (9.425±1.015) of the control group (p=0.049) and the level of salivary lactoferrin of the study group was (8.071± 0.558) compared to (6.610±0.447)  of the control group (p=0.044), while the mean (±sd) of salivary flow rate of the study group was (0.349±0.020) compared to (0.540±0.157) of the control group (p=0.231) and the mean (±sd) salivary pH was (5.935±0.053) ) compared to (5.995±0.153) of the control group (p=0.712). Conclusion: Adolescent pregnancy is linked to increased dental caries experience by altering salivary characteristics, including lactoferrin levels.

    Chronic respiratory disease is famous in poultry farming, mainly in broiler farms. The disease is caused by Mycoplasma species in participation with E. coli. Our study was conducted on CRD of broiler chickens to isolate and determine the resistance of Escherichia coli Seventy-four swabs of the internal organs of broilers (severe respiratory signs) were collected from different areas of Mosul from September 2021 to March 2022. MacConkey agar was used with cefotaxime (1 μg/ml) to grow the isolates, and they were incubated at 37 °C for 24 hours. Colonies were identified according to standard bacteriological methods. The cefotaxime-resistant E. coli isolates underwent DNA extraction. The polymerase chain reaction of Escherichia coli isolates was used for confirmation. The results of the existing study revealed that 61 samples appeared positive for bacterial isolation from 74 (82.4%). All isolates were resistant to an arsenal of antibiotics when testing their sensitivity to antibiotics, including azithromycin, levofloxacin, gentamycin, chloramphenicol…ext. Molecular detection of resistance genes showed that all isolates contained the CTX-M gene by 100%. In comparison, the TEM gene appeared in 52 isolates (85.25%), and only 9 (14.75%) isolates showed the SHV gene. In conclusion, our results shed light on the serious problem in poultry fields, which showed that Escherichia coli isolates contain genes with high resistance to antibiotics, which are the most widely used in the treatment of bacterial infections in these farms, which means the demand for introducing more novel antibiotics in the cure of poultry health problems

    Forced to go online : a case study of learning consecutive and simultaneous interpreting under Covid-19 in Iraq

    Get PDF
    This paper explores the perspectives of Iraqi undergraduates studying consecutive and simultaneous interpreting (CI, SI) in the Department of Translation at Mustansiriyah University in Iraq following the sudden transition to the online environment due to Covid-19. The online mode of teaching and learning has never been adopted in Iraq before. This study, therefore, aims to investigate the challenges and opportunities that have emerged from this unprecedented experience of online learning. It does so by adopting a mixed-method approach combining an online survey and two online focus group sessions. We also conducted two online pilot experiments to test the feasibility of the Zoom app to teach CI and SI synchronously. The main findings of this study suggest that while a synchronous online learning environment would potentially contribute to enhancing interpreting skills, the online mode cannot totally replace actual classes in the Iraqi higher education context unless a rigorous infrastructure is first established

    Exploring sustainable approaches at Dubai Expo 2020: a blend of biophilic and biomimicry designs

    Get PDF
    meticulously curated exhibits with themes such as sustainability and cultural exchange displayed in pavilions dedicated to individual countries. This research study uses biophilic or biomimetic design strategies to assess the sustainability practices employed in a group of pavilions at the Dubai Expo 2020 that employ biophilic and/or biomimetic design strategies. Biophilic philosophy emphasizes nature-based concepts to foster positive relationships between humans and living organisms, whereas biomimicry imitates natural processes/systems for building practices. Incorporating biophilic and/or biomimetic techniques into pavilion design provides visitors with a one-of-a-kind experience while displaying explicit sustainability principles that go beyond the event's existing architectural framework guidelines. The research evaluation process includes architectural structure designs, materials used during production/creation periods, energy efficiency measurements implemented, and sustainable water management plans based on natural ecological systems. It will also evaluate the adherence of each pavilion chosen to genuine sustainability values by analyzing the incorporation of nature-based concepts into its overall design for potential future reference applications. These techniques have significant potential to improve human health, reduce environmental impact, and encourage global resiliency when implemented beyond Dubai Expo 2020. In conclusion, the research aims to inspire sustainable designs well beyond the Dubai Expo 2020 by demonstrating how biophilic or biomimetic practices are crucial facilitators in constructing spaces that maximize human welfare without endangering the environment. It is also a foundational resource for architects and urban planners committed to advancing sustainable architectural practices through future development projects prioritizing human welfare and environmental protection

    Synthesis and reporting of new nanoparticles with diverse properties is important in chemistry. A one-step, rapid and controllable synthesis of the new Fe3O4 surrounded in Ti-MOF nanostructures was carried out with microwave technology. After identifying and confirming the structure, Fe3O4 surrounded in Ti-MOF nanostructures was used as a suitable catalyst with high thermal resistance and recyclable in a three-component reaction of phenylhydrazine, malononitrile and aldehyde to synthesis novel pyrazole derivatives. Continuing investigations on Fe3O4 surrounded in Ti-MOF nanostructures, its antimicrobial properties were tested on Gram-positive bacterial species, Gram-negative bacterial species and fungi bacterial. Identification of Fe3O4 surrounded in Ti-MOF nanostructures with morphology and size distribution technique (SEM), surface area technique (BET), Infrared spectroscopy (FT-IR), Energy-Dispersive X-ray spectroscopy (EDX/EDX mapping), and Vibrating Sample Magnetometer (VSM) were performed. Synthesized pyrazole derivatives with Fe3O4 surrounded in Ti-MOF nanostructures than previously reported methods have less synthesis time and high efficiency. In antimicrobial properties high effects were observed based on MIC, MBC, and MFC values

    No full text
    Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. To date, a lot of research has been conducted to investigate the underlying mechanisms of this disease at both molecular and cellular levels. There is increasing evidence suggesting that autoimmunity is an important factor in the initiation and perpetuation of AF. Autoantibodies are thought to play a pivotal role in the regulation of heart rhythm and the conduction system and, therefore, are associated with AF development. In this review, we have summarized current knowledge concerning the role of autoantibodies in AF development as well as their prognostic and predictive value in this disease. The establishment of the autoantibody profile of separate AF patient groups may appear to be crucial in terms of developing novel treatment approaches for those patients; however, the exact role of various autoantibodies in AF is still a matter of ongoing debate

    Thanks for All Mighty Allah creator of worlds and creating All Human Beings the Greatest Creator, and All Blessings for the Latest Messenger Mohammed and all his Good family. Holly Quran is considered the very purified phrases and the very corrective words at all, within its readings representing the real aspect of Arabic Grammar by which a reflex to be depended to be the basic of holding the complete and the full of Arab Language. In this context, I studied the point of view of Al Kassaie in writing the meanings of Holly Quran, that Book which was lost and had rewritten by Dr. Essa Shuhata. DR. Mahmood Fahmi Al Hujazi in his introduction for this Book after its scripts were deleted, that work represented a work that discovered a lost thing, it presented a book has description related to ancient time. The current research has an introduction addressed by the attitude of ancient towards Holly Quran readings additionally to three main chapters , the first chapter includes methods of AL KASAIE in Holly Quran readings , but the second chapter includes addresses by the attitude of AL KASAIE towards Holly Quran readings, but the third chapter includes and addressed by Samples of criticizing of AL KASAIE in correct Quran readings . After that I ended my research with several conclusions I mentioned to at the last of my own research

    Feminist activist ethnography through Arabic Twitter: Fellowship as a method

    Get PDF
    This article reflects on my journey conducting online ethnography through Iraqi, Saudi, Kuwaiti, and Yemeni feminist Twitters as an Iraqi researcher residing in the United Kingdom. It examines the intersection of online ethnography and feminist activism, emphasising the essential role of long-term immersion in social media spaces as an activist prior to undertaking this type of research. I gained crucial insights into the complexity, fluidity, and emotional dynamics of online spaces and relationships through years of visible presence and engagement with other activists before conducting my ethnography. While some level of intimacy and affiliation with feminist activists existed, the absence of offline encounters posed challenges to forging friendships. However, this difficulty served as a catalyst for developing an ethical method to navigate relationships with participants and address the limitations of a friendship-based approach (Tillmann-Healy, 2003). In this article, I propose an alternative approach centred around a fellowship affiliation,approaching other activists as ‘fellows’ in the two Arabic senses of zamāla and rifqa [peer- and comrade-driven] relationships. This shift in the researcher-participant relationship moves away from the intensity and demanding nature of the ṣadāqah [friendship] relationship. In doing so, it offers a politically powerful stance and a much-needed critical space for constructive debate while maintaining mutual respect and a shared commitment to the cause. The fellowship-based method necessitates activist transparency and critical allyship dedicated to collaboration and unconventional methods of knowledge co-production, promising solidarity, and transcending differences and disagreements. Nonetheless, achieving this can, at times, be challenging. While acknowledging the limitations of the approach, the article recognises that moments of silence or distance can also arise from a sense of activist responsibility and commitment to protecting others

    Risk awareness and demographic characteristics associated with the use of sexual enhancement supplements (SES) among university staff : a cross sectional study in the United Arab Emirates

    No full text
    Background: Sexual enhancement supplements (SES) that have illegal additions of pharmaceuticals or analogues pose a significant health risk, particularly with long-term usage. When supplements are adulterated with PDE-5 inhibitors, dosages can vary widely and there may be an increase in adverse effects and drug-drug interactions which cannot be avoided. Consequently, there is a need to evaluate the public risk awareness towards SES and the associated adverse events as well as explore significant factors associated with knowledge and risk awareness. A cross-sectional community-based study was conducted among University male students and staff at Ajman University, UAE, using a self-administered survey via a web-based electronic link to explore key issues. Results: A total of 1101 male subjects participated in the study and completed the questionnaire. 433 (39.3%) [95%CI: 33.2– 44.5] participants reported using SES products. Of these, 137 (31.6%) [95%CI: 28.6– 37.2] experienced adverse effects from SES product use. SES use was more prevalent among participants aged 60–69 years (OR 2.94; 95 % CI 1.63– 5.28), diabetic patients (OR 2.61; 95 % CI 1.75– 3.90), hypertension patients (OR 2.12; 95 % CI 1.45– 3.1), and those overweight or obese (OR 1.84; 95 % CI 1.44– 2.35). This study indicates that SES is a popular practice among the UAE university staff and students. However, there is a need to implement risk awareness programs to raise public awareness regarding SES use and safety. Regulatory bodies are encouraged to provide additional advice on the proper use and possible risks of consuming SES

    Hyponatraemia and changes in natraemia during hospitalization for acute heart failure and associations with in-hospital and long-term outcomes - from the ESC HFA EORP Heart Failure Long-Term Registry

    Aims: To comprehensively assess hyponatraemia in acute heart failure (AHF) regarding prevalence, associations, hospital course, and post-discharge outcomes. Methods and results: Of 8,298 patients in the ESC-HF Long-Term Registry hospitalized for AHF with any ejection fraction, 20% presented with hyponatraemia (serum sodium <135 mmol/L). Independent predictors included lower systolic blood pressure, estimated glomerular filtration rate (eGFR) and haemoglobin, along with diabetes, hepatic disease, use of thiazide diuretics, mineralocorticoid receptor antagonists, digoxin, higher doses of loop diuretics, and non-use of angiotensin-converting-enzyme inhibitors/angiotensin receptor blockers and beta-blockers. In-hospital death occurred in 3.3%. The prevalence of hyponatraemia and in-hospital mortality with different combinations were: 9% hyponatraemia both at admission and discharge (hyponatraemia Yes/Yes, in-hospital mortality 6.9%), 11% Yes/No (in-hospital mortality 4.9%), 8% No/Yes (in-hospital mortality 4.7%), and 72% No/No (in-hospital mortality 2.4%). Correction of hyponatraemia was associated with improvement in eGFR. In-hospital development of hyponatraemia was associated with greater diuretic use and worsening eGFR but also more effective decongestion. Among hospital survivors, 12-month mortality was 19% and adjusted hazard ratios were for hyponatraemia Yes/Yes 1.60 (1.35-1.89), Yes/No 1.35 (1.14-1.59), and No/Yes 1.18 (0.96-1.45). For death or HF hospitalization they were 1.38 (1.21-1.58), 1.17 (1.02-1.33), and 1.09 (0.93-1.27), respectively. Conclusion: Among patients with AHF, 20% had hyponatraemia at admission, which was associated with more advanced HF and normalized in half of patients during hospitalization. Admission hyponatraemia (possibly dilutional), especially if it did not resolve, was associated with worse in-hospital and post-discharge outcomes. Hyponatraemia developing during hospitalization (possibly depletional) was associated with lower risk. This article is protected by copyright. All rights reserved
