Skin under the microscope: the organization, kinetics and dimensions of skinA histological tyranny has subverted dermatologists and skin biologists and impeded a better understanding of how the skin behaves either at rest or after challenge in some way. The conventional histological section represents ...
In fact, under a microscope you can see wrinkles in smokers as young as 20. Smoking reduces blood flow to the skin and contributes to the breakdown of collagen. Less collagen means more wrinkling. And yes, pursing your lips repeatedly encourages wrinkles, too. You can't reverse the damage...
93 SERS is based on the phenomenon that, under good conditions, molecules are adsorbed onto a precious metal surface to generate a million or more enhancement signals.94,95 Furthermore, the surface plasmon resonance of a particular metal nanoparticle can enhance the relatively weak Raman signals ...

The microstructure and morphology of SFSHs were observed by scanning electron microscope (SEM). As observed in Fig. 2H and Supplementary Fig. 2, both SFSHs and the control polyacrylamide hydrogel after lyophilization exhibited a porous 3-dimentional (3D) structure under a low magnification. With ...
Using a special video epiluminescence microscope we create highly magnified images of your moles that clearly show the mole's structure. This way, one can determine whether the mole is suspicious or not. 皮肤镜是近几年临床上应用较多的一种检查皮肤和毛发的工具,它具有放大皮损的功能,还能利用光学...
Under an Elsevier user license Open archiveHighlights Summary The skin comprises tissue macrophages as the most abundant resident immune cell type. Their diverse tasks including resistance against invading pathogens, attraction of bypassing immune cells from vessels, and tissue repair require dynamic specifi...
Martindale test fabric (worsted wool cloth) was used as a reference textile. Measurements were performed in three different moisture states: dry and two hydrated conditions (moist and wet). In the case of dry conditions, samples were stored under ambient environmental conditions at a temperature ...

During this procedure, a surgeon removesskintissue in very thin layers, carefully looking at each layer under a microscope to see if it’s cancerous and they need to remove more. They stop once they see a layer ofcancer-free tissue. ...
