Study of the 5p3/2 -> 6p3/2 electric dipole forbidden transition in atomic rubidium using optical-optical double resonance spectroscopy

, 2015
Direct evidence of excitation of the 5p3/2 -> 6p3/2 electric dipole forbidden transition in atomic rubidium is presented. The experiments were performed in a room temperature rubidium cell with continuous wave extended cavity diode lasers.

Basal-to-inflammatory transition and tumor resistance via crosstalk with a pro-inflammatory stromal niche

Nature Communications
Cancer-associated inflammation is a double-edged sword possessing both pro- and anti-tumor properties through ill-defined tumor-immune dynamics. While we previously identified a carcinoma tumor-intrinsic resistance pathway, basal-to-squamous cell ...

Mitochondrial Permeability Transition, Cell Death and Neurodegeneration

Cells
Neurodegenerative diseases are chronic conditions occurring when neurons die in specific brain regions that lead to loss of movement or cognitive functions.

Smectic order, pinning, and phase transition in a smectic liquid crystal cell with a random substrate

, 2013
We study smectic-liquid-crystal order in a cell with a heterogeneous substrate imposing surface random positional and orientational pinnings. Proposing a minimal random elastic model, we demonstrate that, for a thick cell, the smectic state without a ...

Single-Cell Computational Strategies for Lineage Reconstruction in Tissue SystemsSummary

Cellular and Molecular Gastroenterology and Hepatology, 2018
Function at the organ level manifests itself from a heterogeneous collection of cell types. Cellular heterogeneity emerges from developmental processes by which multipotent progenitor cells make fate decisions and transition to specific cell types ...

From Cells to Cell Theory: What Would Kuhn Say? [PDF]

, 2013
Cells as we know them today were discovered in the 1600s by Robert Hooke. A couple hundred years later, scientists came to a final conclusion about how cells arose.

Recurrent Highway Networks

, 2017
Many sequential processing tasks require complex nonlinear transition functions from one step to the next. However, recurrent neural networks with 'deep' transition functions remain difficult to train, even when using Long Short-Term Memory (LSTM ...

Overexpression of microRNA-194 suppresses the epithelial–mesenchymal transition in targeting stem cell transcription factor Sox3 in endometrial carcinoma stem cells

Tumor Biology, 2017
The epithelial–mesenchymal transition is the key process driving cancer metastasis. MicroRNA-194 inhibits epithelial–mesenchymal transition in several cancers and its downregulation indicates a poor prognosis in human endometrial carcinoma.

De-repression of the RAC activator ELMO1 in cancer stem cells drives progression of TGFβ-deficient squamous cell carcinoma from transition zones

eLife, 2017
Squamous cell carcinomas occurring at transition zones are highly malignant tumors with poor prognosis. The identity of the cell population and the signaling pathways involved in the progression of transition zone squamous cell carcinoma are poorly ...

The metalloproteinase Papp-aa controls epithelial cell quiescence-proliferation transition

eLife, 2020
Human patients carrying PAPP‐A2 inactivating mutations have low bone mineral density. The underlying mechanisms for this reduced calcification are poorly understood.
