The aim of this study was to evaluate the influence of diabetes mellituson tissue response and mineralization ability of Sealapex®and MTA Fillapex® sealers. Twenty-four Wistar rats were divided into two groups: diabetic and non-diabetic. The materials were placed in polyethylene tubes and implanted into dorsal connective tissue of rats for 7 and 30 days. Six animals from each group received inj...
Sampling was done using 90 post larvae which were produced by reproduction of some broodstocks of Fenneropenaeus indicus in one day and reared in the same situation for 4 months. Samples were divided into 3 groups: high, medium and low growth (based on weight and length). Genomic DNA was extracted from muscle tissue using the phenol-chloroform method. The polymerase chain reaction (PCR) was car...
Using immunohistochemistry, expression of p53, transforming growth factor-alpha (TGF-a), epidermal growth factor receptor (EGFR), c-erbB-2/neu and proliferating cell nuclear antigen (PCNA) was examined in 26 fresh frozen tissue specimens of oropharyngeal squamous cell carcinomas (SCCs). p53 gene mutations were examined by polymerase chain reaction (PCR)/DNA sequencing methods in 22 carcinomas. ...
Salinity adaptation and sea water tolerance are vital, challenging phenomena in the life history of anadromous species such as kuttum fish. Evaluation on feed deprivation in gill chloride cell development of kuttum fish is the aim of this study. Kuttum juveniles that weighed an average weight of 0.5 grams were divided into two groups. One group (control) was fed ad libitum during the experiment...
In vivo toxicity of monocrotophos on key metabolites and enzymes of the protein metabolism was investigated in important tissues of the freshwater fish Clarias batrachus. Fish were exposed to 1/10 and 1/20 of LC50 concentration for 28 days. After 28 days of exposure, some fish were transferred to monocrotophos-free water and kept in the same for 21 days (recovery period) in order to study the r...
Three commercially available real-time reverse transcriptase PCR assays (the Artus RealArt HPA coronavirus LightCycler, the Artus RealArt HPA coronavirus Rotor-Gene, and the EraGen severe acute respiratory syndrome coronavirus POL assay) and three RNA extraction methodologies were evaluated for the detection of severe acute respiratory syndrome coronavirus RNA from 91 stool specimens. The assay...
in order to determine the effects of fish size and weight on its salinity tolerance, the chloride cells (ccs) immunolocalization changes were examined in caspian salmon (salmo trutta caspius) parrs, with the same age (about 2 years old) but different types (type a: 4.88 g, 8.36 cm; type b: 14 g, 11.84 cm; type c: 24.05 g, 14.08 cm). fish survival rate, blood osmolality, gills ccs histological a...
Macrophage elastase and neutrophil elastase are involved in tissue destruction in periradicular lesions. The purpose of this study was to examine these elastases immunohistochemically during development of periradicular lesions induced in rat mandibular first molar by pulpal exposure for 7, 14, 21, 28, and 42 days. Histologically, periapical inflammation developed from 7 to 21 days and then sub...
Freshwater fish, Channa punctatus was exposed to sublethal concentration of a chloroacetanilide herbicide alachlor technical grade and lasso 50% EC for a period of 10 days. The histopathological changes in the gill include: necrosis, vacuolar degeneration, fusion and atrophy of primary and secondary gill lamellae. The tissue damages like degeneration of cytoplasm in hepatocytes, atrophy formati...
