Students’ Contextualization on Technology Use in Learning

This research determines the level of agreement of learners on technology use as a tutor and as a learning tool.  It also discussed how the constructivist theory supports the two domains of technology use as a tutor and as a learning tool.  A questionnaire was used in this descriptive research.  Pilot testing was performed before real information collection involving 112 learners registered from Gulf Medical University, Ajman, UAE medical departments.  The answers for Cronbach's tau-equivalent reliability were calculated using SPSS AMOS software version 23. It was discovered that the coefficient of reliability was 0.71.  This value falls into an acceptable category.  The real collection of information used purposeful sampling involving 138 learners of medical imaging.  A six-point Likert scale has been used to categorize the two primary factors; technology as a tutor and as a learning tool. The results were presented as weighted mean values.  Technology as a tutor is a useful and efficient educational instrument for learners with different abilities. They agreed heavily on its use.  Besides technology as a learning tool fosters cooperation among students.  In the same instance, it motivates learners to participate more in learning operations.  They are very much in agreement with this domain.  The constructivist theory supports that learning takes place when learners are actively involved in classroom activities and other locations conducive to them. Then learning is backed up for a lifetime by real-life experiences

The Influence of Oral Multivitamins Supplementation on Selected Oxidative Stress Parameters and Lipid Profiles among Sudanese Patients with Type-2 Diabetes

AIM: The objective of the current study was to assess the influence of oral multivitamins supplementation on some oxidative stress parameters (serum Vitamin A, C, E, Zinc, Malondialdehyde (MDA)) and lipid profile among Sudanese patients with type- 2 diabetes mellitus (T2DM). MATERIAL AND METHOD: Three hundred Sudanese patients with T2DM and Hundred healthy subjects (control group) were enrolled in this cross-sectional study. Blood was collected after overnight fasting for 10-12 hrs. Fasting plasma glucose (FBG), lipid profiles, Glycosylated haemoglobin (HbA1c%), Serum zinc, Malondialdehyde (MDA), Vitamins A, E, and C levels were measured using standardised laboratory techniques. Data was collected with the help of a structured questionnaire and direct interview. RESULTS: Biochemical parameters of the study population were shown a highly significant difference (P value < 0.05), between the means of serum vitamin A, C, E, Zinc, MDA, HbA1c, triglycerides, HDL, FBG, total cholesterol and LDL. Significant differences in serum vitamin A, C, E, Zinc, MDA, triglycerides, HDL and FBG between people with diabetes who used multivitamins and diabetics who did not use it (P-value < 0.05). CONCLUSION: The study observed a significant increase in serum levels of vitamin A, C & E and other biomarkers parameters in patients with T2DM who take oral multivitamins supplements; such improvement may lead to minimising the diabetic complications. Further studies are needed to explore the possible therapeutic role of multivitamins supplements for T2DM patients

The Association of Prolactin and CRP Biomarkers with the Severity of COVID-19 in Thumbay Hospital, Ajman, UAE

Background: This study aimed to estimate the levels of CRP and PRL in SARS-CoV2 infection and their association with the severity of COVID-19 among patients in Ajman, UAE. Methods and Results: This cross-sectional study was conducted in Thumpay Hospital from 2020 to 2021. The study included 71 patients (55 males and 16 females) with positive SARS-CoV-2 test results. Nasal swab specimens were collected for the COVID-19 test on the day of admission or after one day of admission. COVID-19 diagnoses and severity levels were determined according to the New Coronavirus Pneumonia Prevention and Control Program (7th edition) published by the National Health Commission of China (2020). Serum samples were collected from the patients upon admission. The PRL level was determined using the immune chemiluminescent method by the DXI 800 Beckman Coulter analyzer. The CRP level was determined using the immunoturbidimetric method by the DXC 700 AU chemistry analyzer. Among 71 COVID-19 patients, the great majority were men 55(77.5%), 38(53.5%) being of Indian nationality. In this study, most participants (50.7%) had no history of chronic illnesses. In terms of COVID-19 severity, 24(33.8%) of patients had mild cases, 27(38.0%) had moderate cases, and 20(28.2%) had severe cases. Twenty (28.2%) patients were transferred to the ICU, and 19(26.8%) were intubated. The patients' average age was 47.58±13.63, CRP level - 74.30±71.46 mg/L, and PRL level - 205.1946±168.52 ng/mL. The mean CRP level was highest in severe cases, compared to mild and moderate cases, with a statistically significant difference between mild and severe groups (P=0.000) and mild and moderate groups (P=0.004). The mean PRL level was highest in severe cases compared to mild and moderate cases; however, the differences between the groups were not significant. CRP and PRL levels were greater in the ICU patients than non-ICU patients, with statistically significant differences only for CRP. We found a moderate positive correlation between CRP level and age (r=0.458, P=0.000); a weak positive correlation between PRL level and age was not statistically significant (r=0.201, P=0.093). A moderate positive correlation between CRP level and PRL level (r=0.461, P=0.03) was statistically significant. Conclusion: The current study implies that serum CRP levels might be an important indication of COVID-19 development and severity. A more extensive study with a larger sample size is needed to validate the significance of PRL in disease severity

Nanotube breakthroughs: unveiling the potential of carbon nanotubes as a dual therapeutic arsenal for Alzheimer’s disease and brain tumors

Alzheimer’s disease (AD) and brain tumors are debilitating neurological conditions that pose significant challenges in current medical practices. Existing treatment options for AD primarily focus on symptom management, and brain tumors often require aggressive therapeutic approaches. Novel disease-modifying strategies and therapeutic agents are urgently needed to address the underlying causes of AD pathogenesis and improve brain tumor management. In recent years, nanoparticles (NPs) have shown promise as valuable tools in diagnosing and managing various brain disorders, including AD. Among these, carbon nanotubes (CNTs) have garnered attention for their unique properties and biomedical potential. Their ability to cross the blood-brain barrier (BBB) with ease opens up new possibilities for targeted drug delivery and neuroprotection. This literature review aims to explore the versatile nature of CNTs, which can be functionalized with various biomolecules or substances due to their sp2 hybridization. This adaptability enables them to specifically target cells and deliver medications under specific environmental conditions. Moreover, CNTs possess an exceptional capacity to penetrate cell membranes, making them valuable tools in the treatment of AD and brain tumors. By delving into the role of CNTs in biomedicine, this review sheds light on their potential in managing AD, offering a glimpse of hope for effective disease-modifying options. Understanding the mechanisms of CNTs’ action and their capabilities in targeting and delivering medication to affected cells will pave the way for innovative therapeutic strategies that can improve the lives of those afflicted with these devastating neurological conditions. The exploration of CNTs as a dual therapeutic arsenal for both brain tumors and Alzheimer’s disease holds great promise and may usher in a new era of effective treatment strategies for these challenging conditions

Coexistence of HBsAg/Anti-HBs and HBeAg/Anti-HBe in Sudanese Patients with Chronic Hepatitis B Virus Infection: A Cross-Sectional Study

Background: Seroconversion of hepatitis B surface antigen (HBsAg) to hepatitis B surface antibody (anti-HBs) is a recognized goal of HBV therapy. This dynamic transition responsible for the coexistence of HBsAg and anti-HBs is rarely detected in clinical cases. However, with vaccination and the use of various antiviral drugs, as well as the development of new medical technologies, recognizing the coexistence of HBsAg and anti-HBs has become more common. In addition, mutations in viral genomes, immune status, and human genetic factors may also contribute to such coexistence. The current study was designed to determine the prevalence of the coexistence of HBsAg and anti-HBs and HBeAg and anti-HBe in CHB patients in Sudan. Methods and Results: This was a descriptive cross-sectional study conducted in Khartoum state from November 2018 to January 2019. The study included 70 HBV-infected patients who were positive for HBsAg for more than six months. Blood samples were tested for HBsAg/Anti-HBs and HBeAg/Anti-HBe using Commercial ELISA Kits (Foresight, United Kingdom) and (PRECHEK, USA). Demographic data were collected using a structured questionnaire, and any antiviral agent and laboratory results were also recorded for each participant. The current study showed that one case (1.4%) was reactive for the coexistence of HBsAg/HBsAb and two cases (2.8%) for the coexistence of HBeAg/HBeAb. There was no statistical difference between the coexistence of HBsAg/HBsAb and HBeAg/HBeAb with age, gender, residence, and treatment status. Conclusion: Our study indicates that the frequencies of the coexistence of HBsAg/HBsAb and HBeAg/HBeAb among Sudanese patients with chronic HBV infection were low compared to previous studies in a different population
