Oral HPVs Associated with Risk of Incident Head and Neck Cancers

A prospective study suggests that detection in the oral cavity of certain human papillomavirus types is associated with higher risk of incident head and neck squamous cell carcinoma, suggesting that the role of HPV in HNSCC may be even more important than currently recognized.  More...

Polymer-Based Rapid Test Visually Differentiates Tumor Cells

A polymer-based rapid test has been developed which visually differentiates tumor cells from healthy cells in a tissue section through the use of a simple microscope. Surgeons can already use the test in the operating room which saves time and expenses.  More...

Image: (a) Interferogram obtained using IPM. Sample is still barely seen. However, the OPD information is encoded into the bend of the interference fringes, as can be seen from the enlarged region of interest in (b). (c) The OPD map of the same sperm cell, as digitally calculated from the interferogram shown in (a). All the main morphological features of the cell are discernable. (c, e) Imaging of a sperm cell with an acrosomal vacuole, using: (d) label-based BFM, and (e) label-free IPM. The vacuole is clearly seen as a defect in the OPD map of the IPM image. BFM = bright-field microscopy; IPM = interferometric phase microscopy; OPD = optical path delay (Photo courtesy of Haifler M, Girshovitz P, et al., 2015, and Elsevier publications).
