Quantitative Deformability Cytometry: Rapid, Calibrated Measurements of Cell Mechanical Properties.

Advances in methods that determine cell mechanical phenotype, or mechanotype, have demonstrated the utility of biophysical markers in clinical and research applications ranging from cancer diagnosis to stem cell enrichment. Here, we introduce quantitative deformability cytometry (q-DC), a method for rapid, calibrated, single-cell mechanotyping. We track changes in cell shape as cells deform into microfluidic constrictions, and we calibrate the mechanical stresses using gel beads.

Adjuvant high dose rate brachytherapy for soft tissue sarcomas: initial experience report.

Purpose: Adjuvant high-dose-rate brachytherapy (HDRBT) offers advantages over low dose rate brachytherapy (LDRBT), although there are little data on local tumor control and treatment related toxicity. We report outcome in patients with primary, recurrent, and metastatic extremity and superficial trunk soft tissue sarcoma.

Material And Methods: Eleven patients (12 sites) with intermediate or high grade sarcoma were treated with adjuvant HDRBT following surgical resection.
