In this study, it was aimed to investigate the protective effect of Resveratrol, which has a strong antioxidant on kidney tissues rats experimentally induced with carbon tetrachloride nephrotoxicity, by function tests and histopathology. For purpose, 32 male Wistar Albino were used. The subjects randomly selected, 1st group control, 2nd CCl4, 3rd Resveratrol. 4th divided into 4 groups as CCl4 +...

Case Description- In this clinical report, occurrence of a rare case of canine cutaneous inverted papilloma was discussed. A 4-year-old, intact, male German shepherd dog was presented with multiple skin lesions, located on the inguinal region near the root of penis, which have been progressively growing since two months ago. In close examination of the lesions multiple, firm, painful, and cup-s...

Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported. In leukemia patients, OHL is rarely e...

The olfactory epithelium contains neuronal progenitor cells capable of continuous neurogenesis and is a unique model for studying neural degeneration, regeneration, axon outgrowth and recovery from injury. Matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs), have been implicated in cell turnover, development, migration, and metastatic processes. We used Western...

The retinal pigment epithelium is an important part of the vertebrate eye, particularly in studying the causes and possible treatment of age-related macular degeneration. The retinal pigment epithelium is difficult to access in vivo due to its location at the back of the eye, making experimentation with age-related macular degeneration treatments problematic. An alternative to in vivo experimen...

Fibrosing cholestatic hepatitis (FCH) is an aggressive and usually fatal form of viral hepatitis in immunocompromised patients. It is characterized by progressive cholestasis leading to hepatic failure, and a characteristic histopathological features including: periportal fibrosis, ballooning degeneration of hepatocytes, cholestasis, with minimal inflammation. FCH has been reported almost exclu...

Drusen, the white yellowish deposits that can be seen in funduscopy, are a hallmark of age-related macular degeneration. Histologically, drusen are believed to be dome-shaped or more confluent lipid accumulations between the retinal pigment epithelium and the choriocapillaries. Recent advances in mouse funduscopy have revealed the presence of drusen-like structures in chemokine knockout animals...

Lipid droplets (LDs), which are important storage structures for neutral lipids and organelles of diverse functions, participate in various cellular activities. In this study, BALB/c mice, fed a regular or a high-fat diet, were exposed to the synthetic perfluorinated compound, perfluorooctanoic acid (PFOA). PFOA-exposed mice had altered serum lipid and lipoprotein levels, and hydropic degenerat...

Previous studies of human retinal pigment epithelium (RPE) morphology found spatial differences in density: a high density of cells in the macula, decreasing peripherally. Because the RPE sheet is not perfectly regular, we anticipate that there will be differences between conditions and when and where damage is most likely to begin. The purpose of this study is to establish relationships among ...

Non-exudative age-related macular degeneration, a prevalent cause of blindness, is a progressive and degenerative disease characterized by alterations in Bruch's membrane, retinal pigment epithelium, and photoreceptors exclusively localized in the macula. Although experimental murine models exist, the vast majority take a long time to develop retinal alterations and, in general, these alteratio...
