Mechanosensitive Conjugated Oligoelectrolytes for Visualizing Temporal Changes in Live Cells.

Membrane-intercalating conjugated oligoelectrolytes (COEs) are lipid-bilayer-spanning molecules that serve as fluorescent dyes for bioimaging. However, COE emission has thus far only been capable of visualizing dye location and their preferential accumulation in different membrane-bound intracellular compartments. Herein, we report the first example of environmentally sensitive COEs for visualizing temporal changes in live cells, providing information on the physical properties of intracellular lipid bilayer membranes.

Opto-seq reveals input-specific immediate-early gene induction in ventral tegmental area cell types.

The ventral tegmental area (VTA) is a critical node in circuits governing motivated behavior and is home to diverse populations of neurons that release dopamine, gamma-aminobutyric acid (GABA), glutamate, or combinations of these neurotransmitters. The VTA receives inputs from many brain regions, but a comprehensive understanding of input-specific activation of VTA neuronal subpopulations is lacking. To address this, we combined optogenetic stimulation of select VTA inputs with single-nucleus RNA sequencing (snRNA-seq) and highly multiplexed in situ hybridization to identify distinct neuronal clusters and characterize their spatial distribution and activation patterns.

A culturally adapted survivorship programme for Asian early stage breast cancer patients in Singapore: A randomized, controlled trial.

Background: As cancer mortality rates improve in Singapore, there is an increasing need to improve the transition to posttreatment survivorship care. This study aimed to evaluate the effectiveness of a psychoeducation group (PEG) intervention program compared with usual care to reduce distress for physical symptom and psychological aspects in Asian breast cancer survivors who have completed adjuvant chemotherapy.

Methods: This was a randomized, controlled trial comprising 72 Asian early stage breast cancer survivors who were randomized into the PEG (n = 34) or the control (n = 38) arm.

Quality of life domains important and relevant to family caregivers of advanced cancer patients in an Asian population: a qualitative study.

Purpose: This study aims to identify domains of quality of life (QoL) that are culturally relevant to Chinese caregivers of advanced cancer patients in Singapore and to evaluate content adequacy of currently available instruments for use in the target population.

Methods: English- and Chinese-speaking caregivers of advanced cancer patients receiving care under a tertiary cancer center and/or a community hospice home care/day care provider were recruited for in-depth interviews. The interviews were analyzed using thematic analysis.
