1. A new method q-calculus
Abstract : In q-calculus we are looking for q-analogues of mathematical objects, which have the original object as limits when q tends to 1. q-Calculus has wide-ranging applications in analytic number theory and theoretical physics. The main topic of the thesis is the invention of the tilde operator and the renaissance of the q-addition. READ MORE

2. Gene regulation in psoriatic keratinocytes : microRNAs and cytokine responses
Abstract : Psoriasis is the most common chronic skin inflammation in adults which affects 2-4% of the world population. Keratinocytes are the key structural cells in epidermis which hyper-proliferate and undergo aberrant differentiation in psoriasis. READ MORE

3. The interaction between astrocytes and excitatory synapses in health and disease
Abstract : Synaptic transmission forms the basis of neuronal activity and astrocytes play an integral part in this process. Glutamate is the major excitatory neurotransmitter in the brain and an important function of astrocyte during excitatory synaptic activity involves the uptake of glutamate through astrocyte glutamate transporters (EAATs) and hence shaping the excitatory neurotransmission.

4. Active oxygen involvement in developmental processes in Populus : with emphasis on HipI-superoxide dismutase
Abstract : In plants, oxidative stress is result of disruption of the cellular redox metabolism and is caused by a variety of stress conditions (abiotic and/or biotic). This leads to the induction of several mechanisms that protect against disruption of the redox balance, as well as mechanisms to assist in recovery from toxicity/damage caused by increased cellular levels of reactive oxygen species (ROS).

5. Carbon-Carbon Bond Formation via Radical Cyclization and Transition Metal Catalysis
Abstract : Free radical cyclization methodology has been used extensively in synthesis for manipulation of complex molecules such as alkaloids, terpenes, carbohydrates, peptides and nucleic acids. The methodology has emerged as a result of work by physical organic chemists who determined rate constants for the most common radical reactions used in organic synthesis. READ MORE
