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 ...

Active vision-based localization for robots in a home-tour scenario [PDF]
, 2007 Self-Localization is a crucial task for mobile robots. It is not only a requirement for auto navigation but also provides contextual information to support human robot interaction (HRI).

Optimal multiguidance integration in insect navigation [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance The discovery of “place cells,” “grid cells,” and other spatial cells in the rodent’s forebrain has strengthened the idea that animals navigate their home range environments thanks to a “cognitive map.” Tiny-brained insects, like bees, are also thought to use such a centralized metric mental representation.

Weakening the nuclear envelope: Lamin B receptor in melanoma metastasis
Molecular Oncology, EarlyView.LBR‐driven nuclear fragility supports melanoma invasion. A: Melanocyte presents low LBR (Lamin B Receptor) levels, maintaining nuclear integrity and lamina‐chromatin tethering. B: During malignant progression, upregulation of LBR clusters at the INM (Inner Nuclear Membrane) during confined migration causes local lamina weakening and cholesterol ...

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 ...
