Existence of inelastic supernumerary nuclear rainbow in $^{16}$O+$^{12}$C scattering

, 2017
The existence of a supernumerary nuclear rainbow in inelastic scattering is reported. This is done by studying inelastic $^{16}$O scattering from $^{12}$C, exciting the $2^+$ (4.44 MeV) state of $^{12}$C and elastic scattering at the incident energies in

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

The PIDDosome activates p53 in response to supernumerary centrosomes

Genes & Development, 2017
In this study, Fava et al. show that an increase in the number of mature centrosomes (the main microtubule-organizing centers in animal cells), generated by disrupting cytokinesis or forcing centrosome overduplication, triggers the activation of the ...

Vision in the Anglo-Norman Voyage of Brendan [PDF]

, 2007
This paper considers the concept of vision as it is used in the Anglo-Norman Voyage of Brendan. It is concerned with sight, blindness and understanding particularly in relation to the supernumerary monks – those late-coming monks that join Brendan’s ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Nonsyndromic multiple supernumerary teeth: A case report of 11 supernumerary teeth

Journal of Indian Academy of Oral Medicine and Radiology, 2012
Hyperdontia is an odontostomatologic anomaly characterized by an excess in both erupted and non-erupted teeth number. A23-year-old female patient reported to us with a chief complaint of malaligned teeth and inability to maintain oral hygiene.

String theory and the Classical Stability of Plane Waves [PDF]

, 2002
The presence of fields with negative mass-squared typically leads to some form of instability in standard field theories. The observation that, at least in the light-cone gauge, strings propagating in plane wave spacetimes can have worldsheet scalars ...

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.
