I currently have a Polar F11 (edit: I now use an FT60--the F11 went to Polar heaven about a year ago), although I don't use most of the features. About 10-15 years ago, Polar introduced their OwnCal feature--using heart rate to estimate calories burned during exercise.
Hyphae vs Pseudohyphae. Hyphae and pseudohyphae (singular â hypha and pseudohypha) are two types of filaments that compose vegetative structures found in fungi. All the fungi except few (ex: yeast) form either hyphae or pseudohyphae. Both structures support spores for reproduction and dissemination by exhibiting various physiological and biochemical activities.
Pseudoxanthoma elasticum (PXE) is a rare disorder of degeneration of the elastic fibers with tiny areas of calcification in the skin, back of the eyes (retinae), and blood vessels. PXE is inherited from the parents. 2  PXE typically causes yellow-white small raised areas in the skin folds (flexure areas). 3  PXE can affect areas of the body other than the skin. 4  Treatment of PXE involves monitoring by the doctor and measures to prevent injury and promote overall health.
