Involvement of haptoglobin phenotypes and genotypes in non-muscle invasive bladder cancer: A possible prognostic marker for risk stratification.

The association of haptoglobin (Hp) with various cancers has been reported and also it has been documented that the Hp phenotypes/genotypes have different functional ability. So, we examined phenotypes/genotypes of Hp in newly diagnosed, untreated non-muscle invasive bladder cancer (NMIBC) patients and investigated its prognostic value for risk stratification of the cancer. In eighty NMIBC patients and 80 healthy individuals the Hp genotypes and phenotypes were analyzed using polymerase chain reaction (PCR) and two-dimensional gel electrophoresis (2D-GE), respectively.

Inflammatory cytokines in bladder cancer.

The presence of inflammatory cells and their products in the tumor microenvironment plays a crucial role in the pathogenesis of a tumor. Releasing the cytokines from a host in response to infection and inflammation can inhibit tumor growth and progression. However, tumor cells can also respond to the host cytokines with increasing the growth/invasion/metastasis.

Changes in Cytomorphology, Expression of Retinoblastoma Related Gene, and Superoxide Dismutase Enzyme Activity in Maize Cell Culture Exposed to Silver Nanoparticles.

The ever-increasing use of silver nanoparticles (nAg) in various products necessitates investigation of the behavior of biological systems encountering these particles. In this paper, considering maize as a biological model, the effects of colloidal nAg (<80nm) on its cell culture were investigated. For comparison purposes, silver nitrate was used as a representative of silver ion (Ag).

Source identification of perylene in surface sediments and waterbird eggs in the Anzali Wetland, Iran.

Following the marked increase of perylene concentration in southern coast of Caspian Sea, waterbird eggs were used as biomonitoring agents. Surface sediments and eggs of five bird species were collected from colonies in Anzali Wetland in the above coast for perylene analysis. The perylene concentrations in sediment and egg samples ranged within 70.
