Seroprevalence of Human Cytomegalovirus among Aborted Women in Aden, Yemen
Get PDFHuman cytomegalovirus (HCMV) is one member of Herpesviridae. It can cause serious complications in pregnant women and their fetuses. So, this study aims to determine the prevalence of IgG and IgM against HCMV among aborted women and other related factors in Aden–Yemen. An analytical cross-sectional study was conducted on 88 aborted women. Blood samples were collected and serum HCMV IgG and IgM were analyzed using ELISA. The overall prevalence of IgG and IgM of HCMV infections were 77.6% and 83.3%, respectively. Neither HCMV IgG nor IgM seroprevalence had significantly influenced by age, number of abortions, education level, trimesters, and other factors. It can be concluded that the seroprevalence IgG antibodies of HCMV infections among aborted women were slightly lower than those reported globally whereas the seroprevalence IgM antibodies were higher than most of the previous studies that performed globally. Other causative factors may also contribute to abortion among aborted women. Further research is required to detect the HCMV and other causative agents of abortion in Aden and other southern governments of Yemen using adequate sample size and new advanced techniques
Assessment of Physician Knowledge and Practices Regarding Familial Hypercholesterolemia Screening and Management: A Survey Study
Get PDFFamilial hypercholesterolemia (FH) is a hereditary illness characterized by high low-density lipoprotein (LDL) cholesterol, greatly boosting the risk of early cardiovascular diseases (CVD). This cross-sectional study assessed the knowledge, attitudes, and practices of 100 physicians in Aden, Yemen, from June to August 2023. Participants consisted of 65% females and 35% males, with 54% having more than five years of clinical experience and 56% working in private facilities. The survey revealed that 91% of physicians recognized familial hypercholesterolemia (FH) as a hereditary illness associated with elevated LDL cholesterol levels; however, only 53% were familiar with the diagnostic criteria, and 63% with the clinical detection algorithms. Routine assessment of familial hypercholesterolemia risk factors, such as a family history of early-onset cardiovascular disease, was reported by 49%, while only 28% consistently evaluated these risk factors. While 77% of physicians deemed familial hypercholesterolemia screening essential for patients with elevated LDL cholesterol, only 47% expressed confidence in identifying at-risk individuals. Physicians with more than five years of experience displayed greater awareness of familial hypercholesterolemia diagnostic criteria (60%) and were more willing to routinely assess familial risk factors (56%) compared to their less experienced counterparts (50% and 44%, respectively). Despite significant awareness of familial hypercholesterolemia (FH) and its health implications, notable shortcomings were observed in the comprehension of diagnostic criteria, cascade screening, and adherence to screening protocols. Experienced physicians exhibited enhanced knowledge and confidence, underscoring the need of specialized training programs. Improving FH screening systems is critical for advancing patient care in Yemen and analogous countries
Excessive Internet Use Among Adolescents in Yemen: Prevalence, and Health Implications
Get PDFThe research examines the effects of internet and social media utilisation on the physical and mental health of students aged 15-19 at Al-Bayhani School in Aden, Yemen. The study included 64 students from a total population of 205, who were evaluated on their perceptions of the impact of internet and social media usage on their health. The findings indicated that 75% of children allocate 2 to 6 hours each day to internet usage, exhibiting uniform habits across all school levels. This study also indicated that 23.4% of students encountered heightened isolation, while 60.9% reported experiencing anxiety in the absence of internet connection. Physical health problems including ocular or cervical discomfort, adverse impacts on physical activity and sleep quality, and a considerable detrimental influence on academic performance. The research highlights the necessity for judicious and ethical internet utilisation to alleviate these hazards and optimise its advantages for students
Electronic properties of armchair & zigzag single-walled carbon nanotubes
Get PDFThis paper investigates the role of chirality and its impact on the electronic band structure in armchair and zigzag single-walled carbon nanotubes (SWCNTs). Simulating electronic band gaps for single-walled carbon nanotubes (SWCNTs) with various chiral indices has been done by using the tight-binding model. The increase in chirality results in an increase in the total number of bands in the electronic band structure. A study was conducted on the band gap at Fermi energy (E=0) and it was found that the electronic band structure in armchair and zigzag (SWCNTs) can be either metallic or semiconductor depending on chirality. The diameter of the tube and the band gap value are also provided. The effect of variations in the CNT channel length and oxide thickness on the gate capacitance and drain current of a single CNT have been analyzed. The results suggest that the simulated values are consistent with the theoretical values thus validating the results

The descriptive-analytical method was utilized, and the study sample consisted of 155 male and female teachers in the first semester of the academic year 2023/2024. To collect data, a tool consisting of 30 items graded on a five-point Likert scale was developed. The validity and reliability of the tool were established using known practical methods. The study results indicated that the obstacles facing the application of realistic assessment tools by Islamic education teachers were of moderate level. The obstacles related to the teacher ranked first, followed by those related to the application conditions, and finally, obstacles related to the students ranked last. The study also pointed out the absence of statistically significant differences at the 0.05 level between the means of the study sample\u27s responses attributed to the variables of gender and experience. Based on the results, the study recommended the necessity of professional development for teachers on realistic assessment tools and their application through training courses and workshops
