COVID19 emerged as one of the biggest global public health crises in recent history. Many pharmaceutical companies have raced against time to develop a vaccine, so that the pandemic can be brought under control. The aim of the current study was to assess the acceptance of the COVID19 vaccine among the general population in Iraq. A cross-sectional study was conducted among 1069 respondents from different states of Iraq using questionnaires administered online. Though a total of 77.6% of the respondents agreed to take the COVID19 vaccine when available, a majority (64.3%) said they would wait for some time before taking the vaccine. Around two-thirds agreed to pay a price for the vaccine and the majority (48.6%) preferred the Oxford (AstraZeneca) vaccine. There was a significant association between age, working status, educational level, having family members infected with COVID19 and taking flu vaccine before with acceptance of Covid19 vaccine with P value (<0.001, <0.001, <0.001,0.05, <0.001) respectively. Overall, there is high acceptance willingness among the general population to pay for COVID19 vaccine, once it is available. More education and promotion are needed to assure the public that the vaccine is effective and safe. Keywords: Vaccine, Acceptance, COVID-19, Iraq.

This method depends upon the reduction of the nitro to amino group, condensation with promethazine reagent in the presence of cerium (IV) ions to form a colored dye which exhibits maximum absorption at 606 nm with a high sensitivity (molar absorptivity is 1.292×10 4 l.mol -1 .cm -1 , and Sandell's sensitivity index of 0.025 µg/cm 2 ). Beer' s law is applied within the concentration range of obeyed in 0.4 to 12 ppm with a relative error of -2.73 to + 0.37% and a relative standard deviation of ± 3.84 to ± 0.44%, depending on the concentration level. The method has been successfully applied to the

 Background: Earlier studies focused on description of clinical presentations of patients in the acute phase of Coronavirus disease 2019 (COVID-19). Recently, records have emerged that some patients continue to suffer from symptoms related to COVID-19 after the acute phase of infection. Yet, there is no clear definition for this condition, and different terminology has encompassed such as “post-acute COVID-19 syndrome”, “post-COVID syndrome” and “long COVID”. This study aimed to identify the prevalence of Post-COVID-19 symptoms among the adult population in Baghdad city.  Methods: A cross-sectional study was conducted among 341 Iraqi adults during the period from January to February 2021. All participants are confirmed and recovered cases of COVID-19. An online self-administered questionnaire was used for data collection. The questionnaire includes information about socio-demographic characteristics, presence of co-existing conditions, details about COVID-19 infection, in addition to frequency, type, and duration of symptoms.  Results: The results showed that the mean age of the participants was 30.41 years old and females represented about 65.1% of them. They suffer more frequently from symptoms of depression (6.7%), anxiety (6.2%), and peripheral neuropathy (6.2%) after 12 weeks after the acute phase. Feeling of fatigability was the most frequent symptom mentioned by (12.3%) of the patients that persist for more than 3-4 weeks beyond recovery followed by cognitive impairment in (11.7%) and loss of taste and/or smell in about (11.4%) of them.  Conclusion: The majority of the patients suffered from persistent symptoms of COVID-19 following recovery, some of these symptoms continue for more than 3-4 weeks whereas others persist for longer than 12 weeks.

Background : Infertility is a universal medical problem, 50% was contributed to male factors. Zinc is an important elements for all living cells and it is one of the most important trace elements in our bodies. Nanoparticles, are mall particles, that have a large surface area if compared to their size, this small size, help them to enter into living cells easily. This makes them an essential participant in all biological interactions and their modern applications. The aim was to evaluate the effects of Zinc and Nano zinc on male gonads histology and function. Methods: A double blind case control study, designed to test the effects of Zinc oxide and Nano zinc oxide on 20 rats that were divided randomly into 4 equal groups. Control, Zinc, Nano zinc, and hybrid (zinc and Nano zinc) group. The dose was 0.11mg/kg. Results: There was significant change in in serum Zinc and testosterone, more in ZnNPs containing groups. While the histological picture of testis ameliorated in zinc arm, but worsen in ZnNPs arm of experiment. These results lead to the Conclusion that Nano zinc though improve S. testosterone, it can damage the testicular tissues in certain doses.

In the present work, Brus equation has been used to study the size effect of the quantum dot on the optical properties of some semiconductor compounds ( CdS, ZnS and ZnO). It is found that the absorption wavelength and bandgap energy are dependent on the size of the QD. As the size of the QD decreases, the bandgap energy increases and the absorption wavelength decreases. There is good agreement of the theoretical results of the bandgap energy and absorption wavelength obtained in this study using Brus equation with the published experimental results for the semiconductor compounds mentioned above.
