Severe acute respiratory syndrome: ‘SARS’ or ‘not SARS’ [PDF]

Journal of Paediatrics and Child Health, 2004
Abstract:  Accurate clinical diagnosis of severe acute respiratory syndrome (SARS) based on the current World Health Organization definition is difficult and at times impossible at the early stage of the disease. Both false positive and false negative cases are commonly encountered and this could have far‐reaching detrimental effects on the patients ...

Evolution of CDK1 Paralog Specializations in a Lineage With Fast Developing Planktonic Embryos

Frontiers in Cell and Developmental Biology, 2022
The active site of the essential CDK1 kinase is generated by core structural elements, among which the PSTAIRE motif in the critical αC-helix, is universally conserved in the single CDK1 ortholog of all metazoans.

A dynamic nomenclature proposal for SARS-CoV-2 lineages to assist genomic epidemiology

Nature Microbiology, 2020
The ongoing pandemic spread of a new human coronavirus, SARS-CoV-2, which is associated with severe pneumonia/disease (COVID-19), has resulted in the generation of tens of thousands of virus genome sequences.

SARS-CoV-2 Entry Genes Are Most Highly Expressed in Nasal Goblet and Ciliated Cells within Human Airways [PDF]

Nature Medicine, 2020
We investigated SARS-CoV-2 potential tropism by surveying expression of viral entry-associated genes in single-cell RNA-sequencing data from multiple tissues from healthy human donors. We co-detected these transcripts in specific respiratory, corneal and

Cleavage modification did not alter blastomere fates during bryozoan evolution

BMC Biology, 2017
Background Stereotypic cleavage patterns play a crucial role in cell fate determination by precisely positioning early embryonic blastomeres. Although misplaced cell divisions can alter blastomere fates and cause embryonic defects, cleavage patterns have

Characterization of spike glycoprotein of SARS-CoV-2 on virus entry and its immune cross-reactivity with SARS-CoV

Nature Communications, 2020
Since 2002, beta coronaviruses (CoV) have caused three zoonotic outbreaks, SARS-CoV in 2002–2003, MERS-CoV in 2012, and the newly emerged SARS-CoV-2 in late 2019. However, little is currently known about the biology of SARS-CoV-2.

SAR++: a multi-channel scalable and reconfigurable SAR system [PDF]

IEEE International Geoscience and Remote Sensing Symposium, 2003
SAR++ is a technology program aiming at developing know-how and technology needed to design the next generation civilian SAR systems. Technology has reached a state, which allows major parts of the digital subsystem to be built using custom-off-the-shelf (COTS) components.
