J Med Virol 2021 Apr 10. Epub 2021 Apr 10.

Department of Biology, University of Sulaimani, Iraq, Kurdistan region, Sulaimanyah city.

The recent coronavirus disease 2019 (COVID-19), causing a global pandemic with devastating effects on healthcare and social-economic systems, has no special antiviral therapies available for human coronaviruses (CoVs). The severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) possesses a non-structural protein (nsp14), with amino terminal domain coding for a proofreading exoribonuclease (ExoN) that is required for high-fidelity replication. The ability of CoVs during genome replication and transcription to proofread and exclude mismatched nucleotides has long hindered the development of anti-CoV drugs. Read More

Capturing Cytokines with Advanced Materials: A Potential Strategy to Tackle COVID-19 Cytokine Storm.

Adv Mater 2021 Apr 10:e2100012. Epub 2021 Apr 10.

Institute of Biomedical Health Technology and Engineering, Shenzhen Bay Laboratory, Shenzhen, 518132, China.

The COVID-19 pandemic, induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused great impact on the global economy and people's daily life. In the clinic, most patients with COVID-19 show none or mild symptoms, while approximately 20% of them develop severe pneumonia, multiple organ failure, or septic shock due to infection-induced cytokine release syndrome (the so-called "cytokine storm"). Neutralizing antibodies targeting inflammatory cytokines may potentially curb immunopathology caused by COVID-19; however, the complexity of cytokine interactions and the multiplicity of cytokine targets make attenuating the cytokine storm challenging.

An Examination of Cytomegalovirus, Socioeconomic Status, Race, and Ethnicity on Outcomes after Haploidentical Hematopoietic Transplantation.

Transplant Cell Ther 2021 Apr 16;27(4):327.e1-327.e11. Epub 2020 Dec 16.

Department of Medical Oncology, The Sidney Kimmel Cancer Center at Thomas Jefferson University, Philadelphia, Pennsylvania. Electronic address:

Previous analyses of the effects of race and socioeconomic status (SES) on outcomes after hematopoietic stem cell transplantation (HSCT) have suggested that minority populations and those in disadvantaged groups have inferior outcomes. However, the results of these studies have been inconsistent, potentially due to a multitude of factors, both medical and nonmedical, that have confounded results. In haploidentical (HI) HSCT, an expanding approach with the potential to enfranchise more minority patients, data on the effect of race and SES on outcomes are very limited. Read More
