Purpose To characterize the differences in corneal endothelial wound healing in the presence or absence of Descemet's membrane (DM), in vivo. Methods New-Zealand white rabbits were subjected to 7-mm endothelial wound either by scraping (n = 8; DM intact), peeling (n = 6; DM removed), or a combinatory scrape/peel wound (n = 6). In a second experiment, rabbits underwent peel wound with immediat...

Double-stranded DNA (dsDNA) unconstrained by torsion undergoes an overstretching transition at about 65 pN, elongating the DNA to about 1.7-fold. Three possible structural transitions have been debated for the nature of DNA overstretching: (i) "peeling" apart of dsDNA to produce a peeled ssDNA strand under tension while the other strand coils, (ii) "inside-strand separation" of dsDNA to two par...

Nitrogen (N) fertilization has often been used in excess by farmers to improve commercial yield and the profitability of processing tomato crops. However, N fertilizers greatly affect overall quality, including technological traits, nutritional characteristics, mineral fruit composition. The aim this work was study effects increasing rates on quality when grown Southern Italy conditions. carrie...

Marinated or pickled eggs are enjoyed in cultures across the world, and recipes for these use diffusion to saturate egg white of a hard-boiled with sauce. Inspired by marinated egg, this experiment demonstrates an easy quantitative way. Peeled placed dye solution, penetration distance into is measured as function time using image processing. The distances consistent expected dependence on squar...
