Multi-Dimensional Nanostructures for Microfluidic Screening of Biomarkers: From Molecular Separation to Cancer Cell Detection.

abstract：:Pelvic floor muscle (PFM) strength measurement provides useful information for the study of pelvic floor dysfunctions. Vaginal digital palpation, intravaginal pressure measurements, and the use of a dynamometric speculum represent currently available clinical methods for evaluating PFM strength. However, none of these...

abstract：:Lung cancer is a leading cause of death worldwide. Radiation therapy (RT) is one method to treat this disease. A common side effect of RT for lung cancer is radiation-induced lung damage (RILD) which leads to loss of lung function. RILD often compounds pre-existing smoking-related regional lung function impairment. It...
