    Abstract Introduction: The outbreak of coronavirus disease 2019 (COVID-19) has become one of the most serious pandemics of the recent times. Since this pandemic began, there have been numerous reports about the COVID-19 involvement of the nervous system. There have been reports of both direct and indirect involvement of the central and peripheral nervous system by the virus.
    Objective: To review the neuropsychiatric manifestations along with corresponding pathophysiologic mechanisms of nervous system involvement by the COVID-19.
    Background: Since the beginning of the disease in humans in the later part of 2019, the coronavirus disease 2019 (COVID-19) pandemic has rapidly spread across the world with over 2,719,000 reported cases in over 200 countries [World Health Organization. Coronavirus disease 2019 (COVID-19) situation report-96.,]. While patients typically present with fever, shortness of breath, sore throat, and cough, neurologic manifestations have been reported, as well. These include the ones with both direct and indirect involvement of the nervous system. The reported manifestations include anosmia, ageusia, central respiratory failure, stroke, acute inflammatory demyelinating polyneuropathy (AIDP), acute necrotizing hemorrhagic encephalopathy, toxic-metabolic encephalopathy, headache, myalgia, myelitis, ataxia, and various neuropsychiatric manifestations. These data were derived from the published clinical data in various journals and case reports.
    Conclusion: The neurological manifestations of the COVID-19 are varied and the data about this continue to evolve as the pandemic continues to progress.

    Abstract Background: It is uncertain if patients with prior ischemic stroke are vulnerable to coronavirus disease 2019 (COVID-19) and its complications.
    Methods: We used TriNetX, a global health collaborative clinical research platform with a large global COVID-19 database. COVID-19 infection was identified with a positive lab value for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and related ribonucleic acid (RNA).
    Findings: A total of 604,258 patients with history of ischemic stroke were identified, of which 891 patients (study cohort) were diagnosed with COVID-19. A control cohort with 32,136 patients diagnosed with COVID-19 after January 20

    Abstract Objective: This study aims to investigate the utilization of acute ischemic stroke (AIS) services during the Corona Virus Disease 2019 (COVID-19) pandemic. Based on early observations among healthcare utilization on stroke and other healthcare services, we hypothesized that there would be a persistent significant decline in AIS patients presenting to hospitals as the pandemic has progressed for over a year.
    Method: TriNetX, a large research network, is used to collect real-time electronic medical data. Data on utilization of acute ischemic stroke service was collected for the years 2018, 2019, and 2020 for variables including overall stroke volume and the number of patients that received intravenous tissue plasminogen activator (tPA) and mechanical thrombectomy (MT).
    Result: We found a 13.2-15.4% decrease in total number of AIS patients in 2020 (n 77231) compared with the years 2018 and 2019 (n 88948 and 91270 respectively, p ​< ​0.001). In the year 2020 Stroke volume was significantly lower in Q4 comparing to Q1 (Q1 vs Q4, p ​< ​0.01, while there were no significant differences in stroke volume between Quarters 2, 3, and 4 in 2020 (Q2 vs Q3, p ​= ​0.39, Q2 vs Q4, p ​= ​0.61, Q3 vs Q4, p ​= ​0.18). The Proportion of patients receiving tPA in 2020 was significantly lower compared to prior years (5.4% in 2020 vs 6.4% in 2018 and 6.0% in 2019,
    Conclusion: Despite significant alteration in practices to optimize healthcare delivery and mitigate the collateral impact of the pandemic on care for other conditions, a persistent decline in AIS volumes remains. Delayed presentation, fear-of-contagion, reallocation, and poor availability of health care resources are potential contributors. Prospective evaluation and further investigation for these trends is needed.

    Abstract Maintaining the length of the telomere tract at chromosome ends is a complex process vital to normal cell division. Telomere length is controlled through the action of telomerase as well as a cadre of telomere-associated proteins that facilitate replication of the chromosome end and protect it from eliciting a DNA damage response. In vertebrates, multiple poly(ADP-ribose) polymerases (PARPs) have been implicated in the regulation of telomere length, telomerase activity and chromosome end protection. Here we investigate the role of PARPs in plant telomere biology. We analyzed Arabidopsis thaliana mutants null for PARP1 and PARP2 as well as plants treated with the PARP competitive inhibitor 3-AB. Plants deficient in PARP were hypersensitive to genotoxic stress, and expression of PARP1 and PARP2 mRNA was elevated in response to MMS or zeocin treatment or by the loss of telomerase. Additionally, PARP1 mRNA was induced in parp2 mutants, and conversely, PARP2 mRNA was induced in parp1 mutants. PARP3 mRNA, by contrast, was elevated in both parp1 and parp2 mutants, but not in seedlings treated with 3-AB or zeocin. PARP mutants and 3-AB treated plants displayed robust telomerase activity, no significant changes in telomere length, and no end-to-end chromosome fusions. Although there remains a possibility that PARPs play a role in Arabidopsis telomere biology, these findings argue that the contribution is a minor one.
