Wednesday ’s Daily Brief: Iraq protests, ‘historic’ Syria talks, Chile pulls out of COP25, Guinea-Bissau, South Sudan, new nuclear watchdog chief
A recap of Wednesday’s stories: new Syria talks begin in Geneva; Chile pulls out as host of major climate conference; UN calls for national talks to break cycle of violence in Iraq; UN chief voices ‘serious concern’ over Guinea-Bissau political crisis; IOM suspends South Sudan Ebola screening; UN atomic watchdog appoints new leader.
[East African] Three people have died of a mysterious haemorrhagic fever in South Sudan's Raja county of Western Bhar-el-Ghazal State, raising fears of an outbreak of Ebola.
VERDICT A monoclonal antibody “cocktail”, REGN-COV2, reduced mortality in Ebola virus infection from 51% to 34%, and the current carefully chosen pair of monoclonal antibodies against SARS-CoV-2 reduced viral replication and lung damage in experimental animals. Only randomized controlled trials in humans with COVID-19 will s how whether REGN-COV2 has clinically important benefits, with a favourable benefit to harm balance. Use outside clinical trials is currently generally unwarranted.
New Brunswick, N.J., October 8, 2020 – Johnson &Johnson (NYSE: JNJ) (the Company) today announced the European Commission (EC), acting on behalf of the European Union (EU) Member States, has approved an Advance Purchase Agreement in which the Janssen Pharmaceutical Companies will supply 200 million doses of its COVID-19 vaccine candidate to EU Member States following approval or authorization from regulators. The EU Member States also have the option to secure up to 200 million additional doses.“The COVID-19 pandemic continues to threaten communities worldwide and we have a responsibility to ensure access t...
CONCLUSIONS: Systems-level interventions may alleviate distress for most providers without the need for specialized mental health intervention. Psychotherapeutic support and referral to specialty care should be available to health workers with severe and intense adverse psychological outcomes during and beyond the COVID-19 pandemic. Evidence-based interventions are urgently needed to better serve health workers both during and following epidemics/pandemics. PMID: 33019857 [PubMed - as supplied by publisher]
Recent outbreaks of Ebola virus (EBOV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have exposed our limited therapeutic options for such diseases and our poor understanding of the cellular mechanisms that block viral infections. Using a transposon-mediated gene-activation screen in human cells, we identify that the major histocompatibility complex (MHC) class II transactivator (CIITA) has antiviral activity against EBOV. CIITA induces resistance by activating expression of the p41 isoform of invariant chain CD74, which inhibits viral entry by blocking cathepsin-mediated processing of the Ebola glycopro...
AbstractUltraviolet blood irradiation (UBI) was used with success in the 1930s and 1940s for a variety of diseases. Despite the success, the lack of understanding of the detailed mechanisms of actions, and the achievements of antibiotics, phased off the use of UBI from the 1950s. The emergence of novel viral infections, from HIV/AIDS to Ebola, from SARS and MERS, and SARS-CoV-2, bring back the attention to this therapeutical opportunity. UBI has a complex virucidal activity, mostly acting on the immune system response. It has effects on lymphocytes (T-cells and B-cells), macrophages, monocytes, dendritic cells, low-density...
(University of South Florida (USF Innovation)) University of South Florida Professor Andrew Kramer is utilizing his internationally recognized expertise on the Ebola outbreak and applying it to help pinpoint how COVID-19, which originated in Wuhan, China, became a global pandemic.
We present structures of Ebola and Marburg VP40 matrix layers in intact virus-like particles, and within intact Marburg viruses. VP40 dimers assemble extended chains via C-terminal domain interactions. These chains stack to form 2D matrix lattices below the membrane surface. These lattices form a patchwork assembly across the membrane and suggesting that assembly may begin at multiple points. Our observations define the structure and arrangement of the matrix protein layer that mediates formation of filovirus particles.
