The antigen defined by mAb Ki-67 is a human nuclear protein the expression of which is strictly associated with cell proliferation and which is widely used in routine pathology as a "proliferation marker" to measure the growth fraction of cells in human tumors. Ki-67 detects a double band with apparent molecular weights of 395 and 345 kD in immunoblots of proteins from proliferating cells. We c...
Activity of xanthine oxidase, levels of lipid peroxidation and ascorbic acid were studied in African land snail (Achatina marginatus) from two sites with different pollution potentials. Lipid peroxidation was significantly higher in the snails from the polluted site compared to the value obtained from the same species from the control site. Similarly, the activity of xanthine oxidase in the sna...
To study potential molecular mechanisms of epileptogenesis in the neocortex, the motor cortex of rats was injected with tetanus toxin (TT), and gene expression for 67 kDa glutamic acid decarboxylase (GAD-67), type II calcium/calmodulin-dependent protein kinase (CaMKII), NMDA receptor subunit 1 (NR1), and AMPA receptor subunit 2 (GluR2) was investigated by in situ hybridization histochemistry. I...
This paper is the first taxonomic account of the hydroid orders Anthoathecatae and Leptothecatae from the Caribbean and Pacific coast of Costa Rica. All specimens are currently stored at the reference collection of the Museo de Zoología, Escuela de Biología, Universidad de Costa Rica. Sixteen hydroid species are recorded: Eudendrium carneum, Pennaria disticha, Acryptolaria longitheca, Plumulari...
Background and Aims: This study aimed to assess the severity of tooth decay and related factors in children 5-7 years old, in 2016, in Tehran. Materials and Methods: A descriptive and cross-sectional study was performed on 572 children aged 5-7 years old (300 girls and 272 boys) in public schools in Tehran, Iran. Severity of dental caries (number of decayed, missing, filled surfaces) recor...
