Molecular Oncology, EarlyView.In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Checkpoint blockade and the stem‐like T cell trade‐off
Molecular Oncology, EarlyView.Stem‐like T cells are key to the success of programmed cell death protein 1 (PD1) blockade, as they sustain long‐term anti‐tumor response by continuously generating effector CD8+ T cells. However, how these cells are maintained in cancer is not fully understood. Hor et al.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

A note on two expressions for the spatial power spectrum of the geomagnetic field
Annals of Geophysics, 1996 The spatial power spectrum of the geomagnetic field is usually assumed to be exponential in the spherical harmonic degree (n). An equally valid assumption, however, is that the spectrum at the surface of the Earth's core has a power-law dependence on n ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

The Image Characteristics for Perceived Naturalness
i-Perception, 2011 To identify the visual characteristics that make a scene looks nature, we investigated the relationship between the distribution of spatial frequency spectrum of an image and its perceived naturalness.

Correlation plots of the Siberian Radioheliograph
Solar-Terrestrial Physics, 2017 The Siberian Solar Radio Telescope [Grechnev et al., 2011] is now being upgraded. The upgrading is aimed at providing the aperture synthesis imaging in the 4–8 GHz frequency range [Lesovoi et al., 2011, 2014] instead of the single-frequency direct ...
