Abstract
SARS-COV-2 virus causes (COVID-19) disease; it has become a global pandemic since 2019 and has negatively affected all aspects of human life. Scientists have made great efforts to find a reliable cure, vaccine, or treatment for this emerging disease. Efforts have been directed towards using medicinal plants as alternative medicines, as the active chemical compounds in them have been discovered as potential antiviral or anti-inflammatory agents. In this research, the potential of Saussurea costus (S. Costus) or QUST Al Hindi chemical consistent as potential antiviral agents was investigated by using computational methods such as Reverse Docking, ADMET, and Molecular Dynamics with different proteases COVID-19 such as PDB: 2GZ9; 6LU7; 7AOL, 6Y2E, 6Y84. The results of Reverse Docking the complex between 6LU7 proteases and Cynaropicrin compound being the best complex, as the same result, is achieved by molecular dynamics. Also, the toxicity testing result from ADMET method proved that the complex is the least toxic and the safest possible drug. In addition, 6LU7-Cynaropicrin complex obeyed Lipinski rule; it formed ≤5 H-bond donors and ≤10 H bond acceptors, MW < 500 Daltons, and octanol/water partition coefficient <5.

Abstract
The COVID-19 pandemic has profoundly changed hospital activities, including nuclear medicine (NM) practice. This review aimed to determine and describe the impact of COVID-19 on NM in Europe and critically discuss actions and strategies applied to face the pandemic. A literature search for relevant articles was performed on PubMed, covering COVID-19 studies published up until January 21, 2021. The findings were summarized according to general and specific activities within the NM departments. The pandemic strongly challenged NM departments: a reduction in the workforce has been experienced in almost every center in Europe due to personnel diagnosed with COVID-19 and other reasons related to the coronavirus. NM departments introduced procedures to limit COVID-19 transmission, including environmental and personal hygiene, social distancing, rescheduling of non-high-priority procedures, the correct use of personal protective equipment, and prompt identification of suspect COVID-19 cases. A proportion of the departments experienced a delay in radiopharmaceuticals supply or technical assistance during the pandemic. Furthermore, the pandemic resulted in a significant reduction of diagnostic and therapeutic NM procedures, as well as a reduced level of care for patients affected by diseases other than COVID-19, such as cancer or acute cardiovascular disease. Telemedicine services have been set up to maintain medical assistance for patients. COVID-19 pandemic has reshaped human work resources, patient's diagnostic and therapeutic management, operative models, radiopharmaceutical supplies, teaching, training and research of NM departments. Limits of availability of resources emerged. Nonetheless, we have to provide continuity in care, especially for fragile patients, maintaining infection control measures. Challenges that have been faced should reshape our vision and get us prepared for the future.

Abstract
Community SARS-CoV-2 has profoundly affected traditional elements of learning and teaching in nuclear medicine and diagnostic radiology departments. The response of the nuclear medicine community to the challenges imposed by the COVID-19 pandemic can be described in 3 phases: accommodation, consolidation and optimization, and a return towards normalcy. Adoption of virtual communication platforms has emerged as the crucial interim tool for preservation of trainee supervision and diagnostic imaging education. Development of supplemental teaching materials, refocusing research interests, and relaxation of requirements have all contributed toward stabilization of the residency programs. As we embark on a gradual return to normalcy, many of the virtual solutions that were employed have gained a degree of enduring popularity and may find a place in the postpandemic period.

Abstract
AIM As a follow-up to the international survey conducted by the International Atomic Energy Agency (IAEA) in April 2020, this survey aims to provide a situational snapshot of the COVID-19 impact on nuclear medicine services worldwide, 1 year later. The survey was designed to determine the impact of the pandemic at two specific time points: June and October 2020, and compare them to the previously collected data. MATERIALS AND METHODS A web-based questionnaire, in the same format as the April 2020 survey was disseminated to nuclear medicine facilities worldwide. Survey data was collected using a secure software platform hosted by the IAEA; it was made available for 6 weeks, from November 23 to December 31, 2020. RESULTS From 505 replies received from 96 countries, data was extracted from 355 questionnaires (of which 338 were fully completed). The responses came from centres across varying regions of the world and with heterogeneous income distributions. Regional differences and challenges across the world were identified and analysed. Globally, the volume of nuclear medicine procedures decreased by 73.3% in June 2020 and 56.9% in October 2020. Among the nuclear medicine procedures, oncological PET studies showed less of a decline in utilization compared to conventional nuclear medicine, particularly nuclear cardiology. The negative impact was also significantly less pronounced in high-income countries. A trend towards a gradual return to the pre-COVID-19 situation of the supply chains of radioisotopes, generators, and other essential materials was evident. CONCLUSION The year 2020 has a significant decrease in nuclear medicine diagnostic and therapeutic procedures as a result of the pandemic-related challenges. In June, the global decline recorded in the survey was greater than in October when the situation began to show improvement. However, the total number of procedures remained below those recorded in April 2020 and fell to less than half of the volumes normally carried out pre-pandemic.
