The present research aimed to study the clinical efficacy of novel of impact of magnesium oxide nanoparticles on erythropoietin hormone in blood. Magnesium oxide nanoparticles (MgO NPs) were prepared by the chemical method. The synthesized nanoparticles were diagnosed via X-ray diffraction (XRD) and transmission electron microscopy (TEM). The average particle size was 10.8-12.6 nm. Blood samples were collected from 68 samples, classified as 24 patients with diabetic, 24 patients with diabetic kidney disease, and a control group of 20 healthy males. The age for all groups ranged between 34-72 years old. For evaluating the effectiveness of the erythropoietin (EPO) hormone with MgO NPs, the results showed a significant increase in the level of erythropoietin hormone with MgO NPs compared with the level of erythropoietin hormone without MgO NPs in patients with diabetic kidney disease (DKD). The activating percentage of erythropoietin hormone action was 84.8%. In conclusion, magnesium oxide nanoparticles may exhibit an impact on erythropoietin hormone and its receptor thus improving the “action”, i.e. the binding and interaction between the hormone EPO and its receptors forming their complex. Therefore, the biochemical effects and physiological effects would be more controlled and regulated, thus increasing the level of hemoglobin in the blood and reducing the anemia state.
. Physiotherapy is one of many professions at a high risk of work-related musculoskeletal disorders (WMSds). The authors focused on job risk factors, frequency of occurrence, pain severity, and features of WMSds among physical therapists in 11 governorates of Egypt. Methods. A survey research interview including a standardized questionnaire was conducted with 220 physiotherapists from different clinics and hospitals in 11 governorates of Egypt. Results. The most frequently involved body parts were the lower back (56.82%), followed by the neck and upper back (14.55% and 11.82%, respectively). Physiotherapists who worked at clinics were mostly affected. Physiotherapists working in the orthopaedic field were exposed to most work risk factors (63.18%), followed by those in the paediatric and neurological fields (25.91% and 10.91%, respectively). Moreover, 66.82% of the physiotherapists were affected while using manual therapy methods in comparison with electro-manual and electrical methods. Female physiotherapists were more involved than their male counterparts (62.73% and 37.27%, respectively). There was a moderate positive correlation among the pain level of the affected body segment, the number of cases managed by the physiotherapist per day, and the number of work hours per day. Conclusions. The results suggest that physiotherapists should follow a specific strategy to protect their bodies, especially the back areas. The use of engineering and administrative controls like a proper clinic design, application of electronic and computerized devices, and management of work time may help reduce the incidence of WMSds.
This research investigates challenges and prospects of the dynamic, bilingual education in the light of Pakistan’s language policy. It guides language policymakers to adopt the dynamic, bilingual policy in Pakistan’s education system. However, the researcher revealed that most of the participants willingly favored and practiced the dynamic model of bilingual instruction, but there is no formal policy guide for them. The employment of this education model is valid and feasible in both theory and practice. Besides, readers and policymakers through this research paper would come to know that the dynamic, bilingual education improves students’ socio-cognitive, linguistic performance and functional biliteracy through translanguaging and multimodalities. The issue of monoglossic separation of languages in Pakistan is yet to be solved. Furthermore, the researcher used qualitative, empirical methodology to do analysis and employed open-ended questionnaires to collect data. The researcher used purposive sampling to collect data from sixteen respondents. Additionally, findings show that the subtractive language policy, linguistic politics, the power elite’s monolingualism, parents’ obsession with English, and students’ negative attitudes are challenges to the dynamic, bilingual education. In contrast, Pakistan’s multi-lingual reality along with translingual practices, the use of multimodalities, students’ multi-lingual repertoire, functional biliteracy, and transcultural interaction are some of the prospects of the dynamic, bilingual education policy in Pakistan. Thus, there are both challenges and prospects of the dynamic, bilingual education policy in Pakistan.
This study was conducted to estimate the level of some heavy metals, mainly Lead (Pb), cadmium (Cd), chromium (Cr) and cobalt (Co) in the soil and wheat leaves of some wheat fields in Basra and Maysan province; the sampling areas were Al-Qurna, Al-Madinah, Al-Amara, Kumit, Ali Al-Sharqi, and Ali Al-Gharbi. It was performed the analysis using the Flame Atomic Spectrophotometer. The results indicated an increase in the concentrations of above mentioned these heavy metals in all examined areas; the levels in agricultural soils were found to be exceeding the internationally permissible limits according to EU-2000 standards, the highest levels of pollution were observed at Al- Qurna site with significant differences than other sites for both available and total HMs concentrations in soils. Indicating that the arrangement of the metals according to their available concentrations in the analyzed soil was as follows: lead (21.32 )˃ cobalt (14.63) ˃ chromium (11.06) ˃ cadmium (1.15) as mg/Kg of soil. Additionally, results showed that the highest lead content in the wheat leaves was examined in the Qurna fields (0.175 mg/kg), followed by Amara with a concentration of 0.136 mg/kg. The lowest concentration of lead was observed in wheat leaves in the Kumit fields (0.007 mg/kg). In terms of Cd concentration in wheat leaves, the highest level was observed in Al-Qurna, with a significant difference from other fields, reaching 0.009 mg/kg. The lowest concentration of this HM was recorded in Ali Al-Gharbi, which reached 0.002 mg/kg. The results of the correlation between the available concentration of heavy metals elements and soil characteristics revealed a significant correlation between the soil pH and lead, cadmium, and chromium available concentrations, whereas no correlation with cobalt and a significant correlation between soil EC and lead was observed and a highly significant negative correlation with the cobalt. Results proved the high levels of pollution in all examined areas in Basra and Maysan provinces.
