The Impact of the use of formative evaluation strategy on students' attainment and the survival of its impact on Tajwid course of sixth graders
This study aimed to identify the impact of the use of formative evaluation strategy on students' attainment and the survival of its impact in Tajwid (rules of Qurâan recitation) for sixth graders primary. The study sample, (40 students), was divided randomly into two groups; one experimental studying the issue almaddallazim (The Compulsory Lengthening) and with this group the formative evaluation strategy was used, and the other was a control group studying the same subject in the usual way. Among the most prominent findings of this study: That the experimental group had reached required levels of proficiency in (memory, comprehension), while it did not reach the required level of proficiency in (application). Also, there are differences between the means of the attainment of the experimental and control groups in all levels and in the overall total for all levels. The differences came in favor of the experimental group. In addition, there are no statistical differences found between students' attainment in the test carried out straightaway after the experiment and in the test carried out two weeks later which indicates that students were able to retain what they learnt during the experiment. In light of the findings of this study, various recommendations were proposed, including: emphasising the need to use formative evaluation strategy by teachers of tajwid at the elementary level
Combined administration of buprenorphine and naltrexone produces antidepressant-like effects in mice
Opiates have been used historically for the treatment of depression. Renewed interest in the use of opiates as antidepressants has focussed on the development of kappa opioid receptor (Îș-receptor) antagonists. Buprenorphine acts as a partial ÎŒ-opioid receptor agonist and a Îș-receptor antagonist. By combining buprenorphine with the opioid antagonist naltrexone, the activation of ÎŒ-opioid receptors would be reduced and the Îș-antagonist properties enhanced. We have established that a combination dose of buprenorphine (1mg/kg) with naltrexone (1mg/kg) functions as a short-acting Îș-antagonist in the mouse tail withdrawal test. Furthermore, this dose combination is neither rewarding nor aversive in the conditioned place preference paradigm and is without significant locomotor effects. We have shown for the first time that systemic co-administration of buprenorphine (1mg/kg) with naltrexone (1mg/kg) in CD-1 mice produced significant antidepressant-like responses in behaviours in both the forced swim test and novelty induced hypophagia task. Behaviours in the elevated plus maze and light dark box were not significantly altered by treatment with buprenorphine alone, or in combination with naltrexone. We propose that the combination of buprenorphine with naltrexone represents a novel, and potentially a readily translatable approach, to the treatment of depression
Antidepressant-like effects of BU10119, a novel buprenorphine analogue with mixed Îș/ÎŒ receptor antagonist properties, in mice
TAT-peptide conjugated repurposing drug against SARS-CoV-2 main protease (3CLpro): potential therapeutic intervention to combat COVID-19
The Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that originated in Chinese city of Wuhan has caused around 906,092 deaths and 28,040,853 confirmed cases worldwide (WHO, 11 September, 2020). In a life-threatening situation, where there is no specific and licensed anti-COVID-19 vaccine or medicine available; the repurposed drug might act as a silver bullet. Currently, more than 211 vaccines, 80 antibodies, 31 antiviral drugs, 35 cell-based, 6 RNA-based and 131 other drugs are in clinical trials. It is therefore utter need of the hour to develop an effective drug that can be used for the treatment of COVID-19 before a vaccine can be developed. One of the best-characterized and attractive drug targets among coronaviruses is the main protease (3CL^{pro}). Therefore, the current study focuses on the molecular docking analysis of TAT-peptide^{47â57} (GRKKRRQRRRP)-conjugated repurposed drugs (i.e., lopinavir, ritonavir, favipiravir, and hydroxychloroquine) with SARS-CoV-2 main protease (3CL^{pro} to discover potential efficacy of TAT-peptide (TP) - conjugated repurposing drugs against SARS-CoV-2. The molecular docking results validated that TP-conjugated ritonavir, lopinavir, favipiravir, and hydroxychloroquine have superior and significantly enhanced interactions with the target SARS-CoV-2 main protease. In-silico approach employed in this study suggests that the combination of the drug with TP is an excelling alternative to develop a novel drug for the treatment of SARS-CoV-2 infected patients. The development of TP based delivery of repurposing drugs might be an excellent approach to enhance the efficacy of the existing drugs for the treatment of COVID-19. The predictions from the results obtained provide invaluable information that can be utilized for the choice of candidate drugs for in vitro, in vivo and clinical trials. The outcome from this work prove crucial for exploring and developing novel cost-effective and biocompatible TP conjugated anti-SARS-CoV-2 therapeutic agents in immediate future
Effect of Exposure to Cement Dust among the Workers: An Evaluation of Health Related Complications
BACKGROUND: Cement contains various types of chemicals in addition to lime and silica, and such chemicals cause different health complications and pathogenesis in addition to respiratory disorders. The most important occupational hazards for cement workers are allergy and complication related to respiratory system.AIM: The current study was performed by analysing the questionnaire distributed among the workers and also by the sputum collected from them to study the general health conditions and other life activities.METHODS: Sputum samples were assayed for cytological analysis by Hematoxylin and Eosin staining.RESULTS: In this study, it was observed that majority of these workers suffered from different types of respiratory complications, such as a cough, asthma and lung infections. In addition to this, few subjects showed allergy and other complication like hypertension, diabetes and backache. Moreover, cytological analysis of the sputum was made, and it was observed that majority of the subjects showed severe inflammation.CONCLUSION: Based on these finding, we concluded that long-term cement dust exposure and inhalation causes respiratory complications due to epithelial tissue damage and that can lead to secondary complications as well
Prevalence of Hepatitis C Viral Infection among Diabetes Mellitus Patients in Qassim Region, Saudi Arabia
The worldwide prevalence of Diabetes Mellitus (DM) associated with Hepatitis C Virus (HCV) infection are reported with higher rates of morbidity and mortality. The frequency of HCV is approximately 3-4 million cases each year and in parallel the incidence of DM is increasing alarmingly. World Health Organization (WHO) has specified that DM will be the 7th leading cause of mortality by 2030. The increasing association between HCV and DM has been indicated by some significant reports recently. HCV infection leads to hepatic steatosis and rapid insulin resistance, which in turn upsurges the risk factors for hepatic fibrosis and hepatocellular carcinoma. This study is designed to examine the association between HCV and DM, and different risk factors associated with HCV infection in Qassim region, Kingdom of Saudi Arabia (KSA). A total of 634 blood samples were obtained from diabetic and non-diabetic patients. These blood samples were first screened for HCV infection by enzyme-linked immunosorbent assay (ELISA) and positive samples were again confirmed by TaqMan HCV quantitative test and the viral load in different samples was estimated. The HCV prevalence was identified as 2.5% in diabetic patients with a positive association between HCV and DM (RR= 1.24, OR= 1.77) which is not significant statistically. However, the HCV prevalence among diabetic females was significantly different from males (p<0.05). The behavioural factors had no significant impact to acquire HCV infection. This study indicated a positive association between HCV and DM. Gender was an association factor in the HCV and DM status. Further studies with larger sample size is significant to properly assess the temporal relationship between HCV and DM
The aetiology of social deficits within mental health disorders:The role of the immune system and endogenous opioids
The American National Institute for Mental Health (NIMH) has put out a set of research goals that include a long-term plan to identify more reliable endogenous explanations for a wide variety of mental health disorders (Insel, 2013). In response to this, we have identified a major symptom that underlies multiple mental health disorders â social bonding dysfunction. We suggest that endogenous opioid abnormalities can lead to altered social bonding, which is a symptom of various mental health disorders, including depression, schizophrenia and ASD. This article first outlines how endogenous opioids play a role in social bonding. Then we show their association with the bodyâs inflammation immune function, and review recent literature linking inflammation to mental health âimmunophenotypesâ. We finish by explaining how these immunophenotypes may be caused by alterations in the endogenous opioid system. This is the first overview of the role of inflammation across multiple disorders where we provide a biochemical explanation for why immunophenotypes might exist across diagnoses. We propose a novel mechanism of how the immune system may be causing âsickness-typeâ behaviours (fatigue, appetite change, social withdrawal and inhibited motivation) in those who have these immunophenotypes. We hope that this novel aetiology can be used as a basis for future research in mental health
