New microscope delves beneath skin to detect cancerAshley N. Paddock
Doctors typically use a light and a magnifying glass or tissue biopsy, where a pathologist removes suspiciousskin cellsand looks at them under a microscope, to spot signs of disease. But using a lens and a light is a "17th century" technique that is only 85 percent accurate, at best, and...
knowledge of cells. Therefore, in the context of skin diagnosis, such as skin cancer, it is important to clarify how to maintain sensitive single-cell Raman spectroscopy to the skin. Separation and identification of a single cell often require defined protocols.16It is common to observe multiple...

The aim of this study is to determine if the flavonoid bacailein inhibits the metastasis of skin cancer cells through Ezrin. Methods Cells from a cutaneous squamous carcinoma cell line, A431, were treated with baicalein at 0-60 μM to establish the non-cytotoxic concentration (NCC) range for...
1 mL of PBS and then 500-μL aliquots of the mixture were added to each well. After 10 min at room temperature in the dark, the cells were examined using a fluorescence microscope (Axio Observer Z1; Carl Zeiss, Jena, Germany). Neutral lipids were visualized as red fluorescent ...
According to several authors, these cells show a golden-brown fluorescence when examined under the microscope in ultra-violet light 2 , though other investigations give some evidence to the contrary 3 .关键词: MAST CELLS NEOPLASMS/experimental SKIN/physiology ...
To determine if activin stimulates skin tumourigenesis through autocrine activation of keratinocytes and/or through paracrine/endocrine activation of stromal (mesenchymal or immune) cells, we used transgenic mice expressing a dominant-negative mutant of ActRIB (Alk4) in keratinocytes under control of the...
Despite a long history, the clinical efficacy of cupping therapy is still under debate. This is likely due to the lack of direct evidence for the biological actions of cupping, since the short exposure of cells to vacuum condition rarely has affects cellular activity. In this study, the medici...
