After 24–48 h in 4% paraformaldehyde, the blocks were dehydrated and embedded in paraffin, cut into 4 μm slices, heated overnight in a 60°C incubator, and then dewaxed and stained with H&E and Masson dye. One slice was chosen from each rat and was analyzed under a microscope. Masson staining for the presence of interstitial collagen fiber accumulation was a marker of cardiac fibrosis. The ratio of interstitial fibrosis to the total left ventricular area was calculated from 20 randomly selected microscopic fields in five individual sections per heart using a camera attached to an Leica DM2000 microscope, with images further analyzed by Image-Pro Plus 5.1 (Media Cybernetics, Silver Spring, MD), excluding coronary vessels and perivascular regions.
Apoptosis in cardiac tissue was determined with the DeadEnd Fluorometric TUNEL System (Promega), which catalytically incorporates fluorescein-12-dUTP at DNA strand breaks as previously described [16 (link)]. All sections were counterstained with DAPI (Molecular Probes) at a final concentration of 2 μM. Images were viewed with epifluorescence microscopy (Leica TCS SP5) within 24 hours and analyzed with Image-Pro Plus 5.1 Software (Media Cybernetics, Silver Spring, MD).

Histochemical analyses were performed with ATPase staining using the method of Brooke and Kaiser [22 (link)] with slight modifications. Transverse serial sections of 10 µm in thickness were cut from entire blocks (1.0 × 1.0 × 1.5 cm) with a cryostat microtome (HM525, Microm GmbH, Walldorf, Germany) at −20 °C. Sections were subsequently used for histochemical analysis of myosin adenosine triphosphatase (mATPase) following alkaline (pH 10.70) preincubation. An image analysis system (Image-Pro® plus 5.1, Media Cybernetics Inc., Rockville, MD, USA) was used to examine the stained sections. The muscle fibers were classified as fiber types I, IIA and IIB according to the nomenclature of Brooke and Kaiser. Approximately 500 fibers per sample were counted to analyze the muscle fiber characteristics with Image-Pro Plus software (Image-Pro® plus 5.1, Media Cybernetics Inc., Rockville, MD, USA), including the fiber number percentage (FNP) and fiber area percentages (FAP). FNP shows the ratio of the counted fiber number of each fiber type to the total counted fiber number. FAP was the ratio of a total cross-sectional area of each fiber type to total fiber area measured.

Dihydroethidium probes were used to reflect the level of ROS in the placenta. Dihydroethidium could cross cell membranes at the presence of ROS and stain nuclei bright red by intercalating with the DNA [50 (link)]. At first, the frozen placenta was sliced into 10 μm cross-sections which were then incubated with 5 μmol dihydroethidium (37 °C, 15 min). A Nikon 2000S fluorescence microscope (Nikon, Melville, NY, USA) and the Image-pro Plus 5.0 (Media Cybernetics, Inc., Rockville, MD, USA) were applied respectively to observe and calculate the level of ROS (mean fluorescence intensity per unit area calculated by Image-pro Plus 5.0).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Thicknesses of retinal layers (outer segments + inner segments, outer nuclear layer, outer plexiform layer, inner nuclear layer, inner plexiform layer, retinal ganglion cell layer) were measured for treated and non-treated eyes of WES (n = 4) and Sham (n = 3) rats from 20× magnification images of retinal cross sections obtained via a phase contrast microscope (Leica DMLB, Leica Inc., Buffalo Grove, IL) using an image analysis program (Image-Pro Plus 5.0; Media Cybernetics, Warrendale, PA). Retinal regions spanning 2.5 mm superiorly and inferiorly from the optic nerve head were measured. Each 2.5 mm region was subdivided into five 0.5 mm sections and designated “ F” or “ S” 1–5 for inferior and superior, respectively. Thicknesses for each retinal layer were compared between Sham and WES groups at each location examined. Additionally, thicknesses across all locations examined for each retinal layer were averaged within experimental group and then compared.
RGC nuclei were quantified using an image analysis program (Image-Pro Plus 5.0; Media Cybernetics, Warrendale, PA). RGC counts were averaged in each of the ten regions in both WES (n = 5) and Sham (n = 9) eyes. Additionally, summed RGC counts of superior and inferior regions 1–4 were compared between experimental groups. All nuclei in the RGC layer were counted which included RGCs and any displaced amacrine cell nuclei.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Tissue biopsies were performed one day after bleaching, as it is the optimal time to evaluate any reaction. Rabbits were euthanized, and teeth, gingiva, tongue, buccal mucosa, and hard and soft palates were harvested for histological analysis. All biopsied tissues were placed in different labeled vials containing 4% paraformaldehyde fixative solution at room temperature for at least 48 h. Teeth were decalcified in neutral 10% ethylenediaminetetraacetic acid (EDTA) for four weeks, and the EDTA solution was changed every day to accelerate demineralization. The fixed tissues were embedded in paraffin under vacuum. Serial sections of 4 μm thickness were cut using a rotary microtome, mounted on glass slides, and subjected to hematoxylin and eosin (H&E) and Masson’s trichrome (MST) staining. H&E staining was performed to evaluate epidermal or dermal changes and morphological changes of tissue; MST, the three-color staining in histology, was used to detect collagen fibers. The stained tissues were examined microscopically, in a blinded manner, using a light microscope (CKX41, Olympus, Tokyo, Japan) adapted with a digital camera (Pixel link PL-B686 CU, Canada), at a magnification of ×100, ×200, and ×400. Images were loaded into a computer and processed with Image-Pro Plus 5.1 software (Media cybernetics Inc., Washington, DC, USA).
