a multi‑parameter quantification method was implemented to quantify retinal vascular injuries in microscopic images of clinically relevant eye diseases. this method was applied to wholemount retinal trypsin digest images of diabetic akita/+, and bcl‑2 knocked out mice models. five unique features of retinal vasculature were extracted to monitor early structural changes and retinopathy, as well ...

magnetic force microscope ( mfm ) is a powerful technique for mapping the magnetic force gradient above the sample surface. herein, single-wall carbon nanotubes (swcnt) were used to fabricate mfm probe by dielectrophoresis method which is a reproducible and cost-effective technique. the effect of induced voltage on the deposition manner of carbon nanotubes (cnt) on the atomic force microscope (...

atomic force microscopy (afm) is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. afm is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. there are several methods and many ways to modify the tip of the afm to investigate surface properties, ...

herpetosiphon giganteus is a filamentous gliding bacterium. gliding motility is the movement of the cells over surfaces without the aid of flagella. the mechanism responsible for bacterial gliding motility has not been known and there are only a few data on herpetosiphon giganteus. the aim of this study was to observe the ultrastructure and negative staining of isolated strains of herpetosiphon...
