Cornus bretschneideri L.Henry (Cornaceae), a shrub or small tree, is a potential horticultural plant or a soil-fixing plant. In this study, the complete sequence and characterization of the chloroplast genome of C. bretschneideri was studied. The size of the chloroplast genome is 158,270 bp in length, including a large single copy region (LSC) of 87,466 bp, a small single copy region (SSC) of 18,730 bp, and a pair of inverted repeat (IR) regions with 26,037 bp. The GC content of the chloroplast genome was 37.86%. Moreover, a total of 132 functional genes were annotated, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The neighbor-joining phylogenetic tree suggested that C. bretschneideri was closely related to C. sanguinea and C. macrophylla.

Elymus tangutorum (Nevski) Handel-Mazzetti (Poaceae: Triticeae), a hexaploid perennial herb, is a kind of forage plant with large biomass. In this study, the complete plastome sequence of E. tangutorum was reported. The size of the plastome is 134,949 bp in length, including a large single copy region (LSC) of 80,556 bp, a small single copy region (SSC) of 12,767 bp, and a pair of inverted repeat (IR) regions with 20,813 bp. Moreover, a total of 131 functional genes were annotated, including 85 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The maximum likelihood (ML) phylogenetic tree suggested that E. tangutorum was closely related to Elymus libanoticus and Dasypyrum villosum.

AbstractIntroduction Coronavirus disease 2019 (COVID-19), originated in late December 2019, in Wuhan, China. The World Health Organization declared a pandemic on 11 March 2020, with the rapidly rising number of cases and fatalities over hours and days all around the world.Aim To assess the number and the trend of the poisoning consultations to the Poison Unit in the Mansoura Emergency Hospital during the era of the COVID-19 pandemic in 2020.Methods We collected data from the database of the Poison Unit and the Statistics Department of the Mansoura Emergency Hospital of the cases and the calls coming to the Poison Unit in the period from January 2018 through December 2020. We compared 2020 exposures to 2018–2019 exposures by using simple logistic models to provide effect size with odds ratios.Results The Mansoura Emergency Hospital Poison Unit treated 1752 cases in 2020, compared to 2210 cases in 2018 and 2539 cases in 2019. The Poison Unit treated 26% fewer patients in 2020 than either 2018 or 2019), while calls increased nearly 50% in 2020 than in 2018 and 2019. Calls came more frequently from the general public than health professionals and more frequently in afternoon and evening than in the morning. There was a significant increase in the cases of pharmaceuticals ingestion, food poisoning, corrosives and households exposures in 2020 compared to 2018 and 2019 (p-value 0.004, 0.024, and 0.0002, respectively; odds ratio 1.224, 1.691, and 1.692, respectively).Conclusion The COVID-19 pandemic changed the pattern of poisoning exposure and use of the Poison Control Center services.
