Hysteresis and Negative Resistance Regimes in Membrane Perturbations by Chrysin

Authors: Sai Venkatesh Balasubramanian
Comments: 5 Pages.

The growing concerns about pro-oxidant nature and toxicity during interaction of flavonoids such as chrysin and associated metal complexes with the cell membrane has led to investigations on membrane perturbations by the same. However, the Cyclic Voltammetry (CV) results show signs indicative of a hysteesis behavior. Taking cue from this, the present work is directed at a nonlinear analysis and characterization of the CV results of membrane perturbations by Chrysin and its copper and iron complexes. Plots of the Voltage-Resistance (V-R) and Voltage-Capacitance (V-C) relations show that while the capacitance is constant independent of voltage, the V-R behavior shows an interesting Hysteresis pattern with negative resistance peaks being seen. Presence of dosage-independent chaos is ascertained using the Lyapunov Exponent. The present work offers an insight into the nonlinear behavior underlying the mechanics of flavonoid-cell membrane interaction and might be the first step in a series of studies focused on the role of nonlinearity and chaos on toxicity.

DNA Molar Masses - Unsung Heroes of the Code of Life?

Authors: Sai Venkatesh Balasubramanian
Comments: 5 Pages.

While the revolutionary field of Genetics along with its immense applications needs no introduction, recent models of the Deoxyribonucleic Acid (DNA) reading process have proposed a complex system of mechanical oscillators giving rise to a solitonic transmission wave, dependent largely on the ‘context’, which consists of the structures and masses of the DNA Nucleotides. This observation logically raises the question of whether the masses of nucleotides in particular, contribute to the well-known high informational efficiency and capacity of the DNA. In this context, the present work purports to a simple experiment, where the genome sequences of three virus species are used to derive a sequence of the corresponding nucleotide molar masses. Along with the original nucleotide-molar mass associations, three fictitious associations are proposed, and for each of the four associations, the histograms of molar mass occurrences are plotted. It is seen that the original association alone leads to a distribution resembling the normal probability distribution, leading to the hypothesis that this preference affects choice of molar mass by nature, which then results in the efficiency of the solitonic transmissions and thus ultimately, the observed informational efficiency of the genetic codes.

Study the Regulation of the “nos” Genes of Bradyrhizobium Japonicum

Authors: Alicia Abarca Cifuentes, Maria Jesus Delgado
Comments: Alicia Abarca Cifuentes as Final project student, 26 Pages.

The goal of this Project is to study the regulation of the “nos” genes of Bradyrhizobium japonicum, which encodes the nitrous oxide reductase enzyme responsible for the reduction of the greenhouse gas nitrous oxide (N2O). To achieve this goal, I am using transcriptional fusions of the promoter regions of “nos” genes to lacZ reporter gene I have transferred by conjugation a nosRlacZ fusion into the parental strain USDA110 and a-mutant strain lacking the regulatory protein RegR. The transconjugants obtained were grown in minima media with different concentrations of oxygen. Cells have been obtained by centrifugation and I have measured the beta-Galactosidase activity of cells.
