Abstract
This study investigates the hazardous effects of lead on the histological and genotoxic parameters of the fish, Oreochromis niloticus. Present work was conducted in a series of three steps. In first step, acute toxicity, LC50 and lethal lead concentration were measured using Probit analysis method. LC50 value and lethal concentration for O. niloticus was measured as 77.673 mgL-1 and 150.924 mgL-1, respectively. In second step, histological changes were assessed by preparing slides of tissues of the gills, liver and kidney of both control and Pb-stressed O. niloticus and examining the respective tissues under the light microscope. The inferences showed significant histological alterations (p<0.05) in the gills of Pb-exposed fish including necrosis, edema, vascular congestion, shortening and curling and lifting of the epithelium of secondary lamella in gills. The cellular degeneration and dilation of sinusoids in liver and loss of hemopoietic tissue, necrosis and edema in kidney was observed. Histomorphometry of the liver showed a decrease in diameter of the central vein and hepatocyte along with an increase in width of sinusoids. The histomorphometry of kidney showed an increase in the diameter of renal corpuscle, glomerulus, proximal and distal convoluted tubules. The nuclear anomalies were studied in the RBCs of fish. Non-parametric Mann-Whitney U-test was conducted to compare nuclear abnormalities and the frequency of micronuclei among the control and lead-treated fish groups. Results declared an increased micronucleus, notched and de-shaped nuclei frequency, in RBCs of fish exposed to lead as compared to control group.

Abstract
This work incorporates experimental methods based on Atomic Force Microscopy (AFM) in order to extract the physical and mechanical characteristics of the head and neck cancer (HN-5) cell line such as cell topography, modulus of elasticity and viscoelastic properties. The initial parameters to determine the mechanical properties are obtained by extracting information from cantilever's force-displacement curve and vertical and horizontal displacement. Next, the changes in elasticity modulus at different points in the cell are attained using the experimental results, followed by studying the differences of these properties at various spots of the cell. Furthermore, cellular folding factor is calculated as a significant property in diagnosing the extent of cancer progression. Moreover, parameters such as adhesion and intermolecular forces are measured which are involved in the first phase of manipulation and during the application of the cantilever force to the particle. Finally, after calculating the indentation depth and contact radius using contact theories, critical manipulation time and force are obtained. Through modeling the cell, the creep function, the spring constant and the damping coefficient corresponding to the cell, are also extracted.
