The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Immune Response, Inflammation, and the Clinical Spectrum of COVID-19
Frontiers in Immunology, 2020 The current COVID-19 pandemic began in December 2019 in Wuhan (China) and rapidly extended to become a global sanitary and economic emergency. Its etiological agent is the coronavirus SARS-CoV-2.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

JACC: Case Reports, 2020 Ventricular septal rupture (VSR) following myocardial infarction is rare in the reperfusion era. The decrease in patients presenting with myocardial infarction during the coronavirus-2019 (COVID-19) pandemic could result in more frequent VSR. This report

Presenting Pompeii: Reconciling Relationships between Configuration and Conservation [PDF]
, 2013 Mark Twain’s idealized testimonial in his travelogue Innocents Abroad is not a revolutionary phenomenon. Pompeii has long been considered a city with breathtaking preservation, but the extent of preservation has been a recent source of controversy.

Continuous spectrum, point spectrum and residual spectrum of operator matrices
Linear Algebra and its Applications, 2010 Let \(M_C\) denote a \(2\times 2\) upper triangular operator matrix of the form \(M_C=\left(\begin{smallmatrix} A&C\\0&B\end{smallmatrix}\right)\), which is acting on the sum of Banach spaces \(X\oplus Y\) or Hilbert spaces \(H\oplus K\). The authors of this paper characterize the sets \(\bigcap_{C\in B(Y,X)} \sigma_c(M_C)\), \(\bigcap_{C\in B(K,H ...
