Here, we describe a simple, inexpensive and fast clearing method to resolve the 3D structure of both mouse and human white adipose tissue using a combination of markers to visualize vasculature, nuclei, immune cells, neurons, and lipid-droplet coat proteins by fluorescent imaging.

Obesity is a growing global public health issue. It has been previously associated with lymphatic dysfunction, suggesting a vital crosstalk between the adipose tissue and the lymphatic system. Here, we propose an accessible methodology allowing the distinct labeling of blood and lymphatic vasculatures within the subcutaneous adipose tissue.

Presented here is a protocol to deliver oligonucleotides such as small-interfering RNA (siRNA), micro-RNA mimics (miRs), or anti-micro-RNA (anti-miR) into mature adipocytes to modulate protein and micro-RNA expression.

Two recent technologies-tattoo and textiles-have demonstrated promising results in cutaneous sensing. Here, we present the fabrication and evaluation methods of tattoo and textile electrodes for cutaneous electrophysiological sensing. These electronic interfaces made of conductive polymers outperform the existing standards in terms of comfort and sensitivity.

The increase of molecular biomarkers to be tested for non-squamous non-small cell lung cancer (NS-NSCLC) care management has prompted the development of fast and reliable molecular detection methods. We describe a workflow for genomic alteration assessment for NS-NSCLC patients using an ultra-fast-next generation sequencing (NGS) approach.
