Kidneys were fixed in 10% buffered neutral formalin, further processed and paraffin embedded. Three micrometer sections were cut and stained using a Periodic acid Schiff staining kit (Sigma) according to the manufacturers' instructions. Tissues were imaged using a Leica DN2000 microscope and micrographs taken using Leica Application Suite software. Image analysis was performed using ImageJ; all images were contrast enhanced using the same parameters.
Glomerulosclerosis was scored for each glomerulus as follows: 0 = normal glomeruli; 1 = up to 25% involvement; 2 = 25%‐50% involvement; 3 = 50%‐75% involvement; 4 = over 75% involvement. The glomerulosclerosis index was calculated according to the formula ([1 × N1] + [2 × N2] + [3 × N3] + [4 × N4])/(N0 + N1 + N2 + N3 + N4), where Nx is the number of glomeruli with each given score.

Kidneys were fixed in 10% buffered neutral formalin, further processed and paraffin embedded. 3μm sections were cut and stained using a Periodic acid Schiff staining kit (Sigma) according to the manufacturer’s instructions. Tissues were imaged using a Leica DN2000 microscope and micrographs taken using Leica Application Suite software. Image analysis was performed using Image J; all images were contrast enhanced using the same parameters.
Glomerulosclerosis was scored for each glomerulus as follows: 0=normal glomeruli; 1=up to 25% involvement; 2=25–50% involvement; 3=50–75% involvement; 4=over 75% involvement. The glomerulosclerosis index was calculated according to the formula [(1xN1)+(2xN2)+(3xN3)+(4xN4)]/(N0+N1+N2+N3+N4) were Nx is the number of glomeruli with each given score.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
