Article Title: Diabetes Mellitus Aggravates Hemorrhagic Transformation after Ischemic Stroke via Mitochondrial Defects Leading to Endothelial Apoptosis

doi: 10.1371/journal.pone.0103818

Figure Lengend Snippet: A: Cell proliferation (n = 7). B: ATP contents (n = 10). C: Mitochondrial membrane potential, determined by tetramethyl rhodamine methyl ester (TMRM) intensity (n = 10). The scale bar indicates 100 µm. D: reactive oxygen species (ROS) levels (n = 10). E: Binding of 4-hydroxy-2-nonenal (4-HNE), an indicator of lipoperoxidation by ROS. F: Enzymatic activities of MMP-2 and MMP-9 by gelatin zymography (n = 3). All data are expressed as mean ± SEM (shown as ratio to 5.5 mM). *P<0.05, **P<0.01 vs. 5.5 mM (Dunnet's test). HBMVECs, human brain microvascular endothelial cells.

Article Title: Renal Impairment with Sublethal Tubular Cell Injury in a Chronic Liver Disease Mouse Model

doi: 10.1371/journal.pone.0146871

Figure Lengend Snippet: ( A ) Representative images of 4-hydroxy-2-nonenal (4-HNE) immunostaining in the kidneys of control and DDC-fed mice at days 1, 3, and 7. 4-HNE staining on kidney tissue was digitally analyzed and presented as percentage of positive staining area per field; control ( white bar ) and DDC-fed mice ( black bar ) at days 1, 3, and 7. Scale bar = 50 μm. ( B ) Representative images of 3-nitrotyrosine (3-NT) immunostaining in the kidneys of control and DDC-fed mice at days 1, 3, and 7. The ratio of 3-NT-positive cells to total tubular cells are presented as a percentage; control ( white bar ) and DDC-fed mice ( black bar ) at days 1, 3, and 7. Scale bar = 50 μm. Data are presented as means ± SEM. * P < 0.05 compared with control mice.

Article Snippet: After rinsing and the blocking process by 1% bovine serum albumin and 0.1% cold water fish-skin gelatin for 30 min at room temperature, slides were treated with negative control reagents or the following optimally diluted primary antibodies: anti-Ly-6G/-6C (rat monoclonal, 1:50; Abcam, Cambridge, MA, USA), anti-leukocyte common antigen (LCA) (mouse monoclonal, 1:200; Dako, Glostrup, Denmark), anti-Ki67 (mouse monoclonal, 1:100; Novocastra, New Castle, UK), anti-4-hydroxy-2-nonenal (4-HNE) (rabbit polyclonal, 1:500; Merck Millipore, Darmstadt, Germany), and anti-3-nitrotyrosine (3-NT) (rabbit polyclonal, 1:100; Merck Millipore) for 1 hour at room temperature.

Techniques: Immunostaining, Staining
