Introduction: COVID-19 is a new viral illness that can affect the lungs and airways with lethal consequences leading to the death of the patients. The ACE2 receptors were widely disturbed among body tissues such as lung, kidney, small intestine, heart, and others in different percent and considered a target for the nCOVID-19 virus. S-protein of the virus was binding to ACE2 receptors caused downregulation of endogenous anti-viral mediators, upregulation of NF-κB pathway, ROS and pro-apoptotic protein. Nrf2 was a transcription factor that's play a role in generation of anti-oxidant enzymes. Aim: To describe and establish role of Nrf2 activators for treatment COVID-19 positive patients. Methods: We used method of analysis of the published papers with described studies about COVID-19 connected with pharmacological issues and aspects which are included in global fighting against COVID-19 infection, and how using DMF (Nrf2 activator) in clinical trial for nCOVID-19 produce positive effects in patients for reduce lung alveolar cells damage. Results: we are found that Nrf2 activators an important medication that's have a role in reduce viral pathogenesis via inhibit virus entry through induce SPLI gene expression as well as inhibit TRMPSS2, upregulation of ACE2 that's make a competition with the virus on binding site, induce gene expression of anti-viral mediators such as RIG-1 and INFs, induce anti-oxidant enzymes, also they have a role in inhibit NF-κB pathway, inhibit both apoptosis proteins and gene expression of TLRs. Conclusion: We are concluded that use DMF (Nrf2 activator) in clinical trial for nCOVID-19 positive patients to reduce lung alveolar cells damage.

The aim: To determine the pandemic’s impact on worldwide psychological suffering and its consequences for vulnerable groups. Materials and methods: 200 participants (mean 66.5% males) from 6 provinces of central and southern Iraq responded to the survey for 6 months. Mental signs and symptoms were assessed using the Patient Health Questionnaire and State Trait Anxiety Inventory, respectively. Over 55% of the post-Covid respondents had depression; the male gender was higher than female gender (56% vs. 44%). About 44% of the post-Covid respondents had Nervousness, 59% of them was male. Participates had moderate level of confusion & memory loss about 73%, however, the male gender was greater suffering from it than female (72% vs. 28%). Results: Results show that Post Covid-19 patients have high depression, Nervousness, and memory loss, and also Male gender with Covid-19 have a severe level of depression, Nervousness, memory loss as compare with the female gender. Conclusions: Post Covid-19 patients have high depression, Nervousness, and memory loss as compared with those without covid-19 one. Patients who have a history of psychological problems inpatient with Covid-19 must be taken and treated in combination with a protocol of covid-19 management. The male gender with Covid-19 has a severe level of depression, Nervousness, memory loss as compared with the female gender.

Introduction: The first case of coronavirus disease 2019 (COVID-19) in holy Najaf city in February 22, 2020. The outbreak then rose up all over Iraq from 519 cases and 20 deaths in June 2, 2020 to 3484 cases and 72 deaths per day in August 10, 2020 per 24 hours. Aim: The aim of the study is to describe the distribution of confirmed cases by age, demographic factors, isolation, comorbidities and case fatality rate. Methods: Prospectively collected and analyzed data on patients with laboratory-confirmed 2019-nCoV infection by real-time RT-PCR and next-generation sequencing. The demographic and clinical outcomes data of 1153 diagnosed patients were collected from consecutive patients, analyzed, and described. About two third of cases 789 (68.4%) acquired infection through contact with positive patients. Results: The reported cases were 743 (64.4%) males and 410 (35.6%) females with large number among age range 21 to 50 years. The most frequent presenting symptoms were fever, sore throat and dyspnea or cough, most of patients; 868 (75%) patients were isolated at home versus 285 (24.72) patients required hospitalization which represented the intermediate and sever cases. The overall case fatality rate was 2.4%. Conclusion: Most of COVID-19 cases in this localitywere male from urban areas. The common onset symptoms were the fever, sore throat and dyspnea or cough. Majority of cases were isolated and treated at home. The estimated case fatality rate was within the global range (2.4%).

Background: Ischemic cerebrovascular disease causes oxygen deprivation to the brain tissue. Reperfusion, which can occur spontaneously through dissolution of the thrombus or by therapeutic recanalization, leads to the generation of reactive oxygen species (ROS)and induces inflammation which further damages the brain tissue.Methods: Animal model of rats were subjected to general anesthesia during which an occlusion of bilateral common carotid arteries was done for half hour then reperfusion for one hour with and without prior treatment with Bardoxolone 3 mg/kg intraperitoneal (i.p) 24 hr. Brain tissues were sent for histopathological scoring assessment as well as for estimation of Nrf2, NF-κB and MDA levels. Results: The level of nuclear Nrf2 was increased significantly (P<0.05) in bardoxolone group. Brain tissue damage scores and the levels of NF-κB and MDA were decreased significantly (P<0.05) in rats treated with bardoxolone. Histological results in bardoxolone group showed reduced structural lesions. Conclusions: Neuroprotective effect of bardoxolone against cerebral I/R injury via upregulation of nuclear Nrf2 protein and down-regulation of inflammation and oxidative stress.

In the present study, density function theory (DFT) tool is used to compute structural, electronic and optical properties for hexagonal-boron-nitride (h-BN) nanosheet, perfect and defected (one carbon atom remove) graphene (G)/boron-nitride nanoisland. The basis set 6-31G is utilizing in a present study with hybrid function (B3LYP). Relaxation calculation is showing that all bond length between atoms are agreement with theoretical and experimental measurements, also the surface of all systems was remain in plane form. Energy gap calculation shows that a h-BN nanosheet has insulator nature. Doping h-BN by carbon (C) and defected (by remove one carbon atom) the energy gap is modifying and reduce from (6.006) to (3.464 and 1.569) eV, respectively. In the other hand, doped and defected mechanism enhance the conductivity of h-BN nanosheet. UV-Visible calculation is showing that h-BN absorbing in the ultra-violet region, doped and defected nanoisland were absorbed light in the visible region of electromagnetic radiation and shifted to long wavelength (Low energy). Fourier transformation-infrared radiation (FT-IR) calculations are showing that all active group are appearing like (C-C), (C-B), (C-N), (B-H) and (N-H) and approximately agreement with experimental measurements. Light harvesting efficiency (LHE) calculation is concluding that h-BN/G nanoisland have high ability to harvest light compared with h-BN nanosheet and defected h-BN/G nanoisland. Results show that higher occupied molecular orbital (HOMO) is being distributed above minimum conduction band (CBM) of titanium dioxide (TiO2), and lower unoccupied molecular orbital (LUMO) is being populate below iodine/ tri-iodine (I/I3) electrolyte. Meanwhile, all nanostructure is having ability to generate pair electron-hole. Finally, results show that the measurements are indicating that it is possible to apply the composites under study in the field of photonic devices especially in solar cell field.
