Dr. Safee Ullah Chaudhary will represent the Khwarizmi Science Soceity at the Buraq Space Camp on 25th December 2017. The talk will encompass the vast field of computational biology and its applications.
The cornea is the clear front of the eye and its clarity is important for the transmission of light to the retina for visual perception. The corneal surface is composed of an epithelium that is renewed by stem cells located at the periphery of the cornea, in a region known as the limbus. These so-called limbal stem cells can become deficient or dysfunctional as a result of many causes including chemical and thermal burns to the eye, hereditary causes such as Aniridia and Ectodermal Dysplasia, inflammatory diseases such as StevensJohnson Syndrome and Mucous Membrane Pemphigoid, and iatrogenic causes such as radiation therapy and topical chemotherapy. In the resulting disease of of Limbal Stem Cell Deficiency the corneal epithelium cannot be maintained resulting in chronic epithelial defects and the surface becomes replaced by the conjunctival epithelium and its blood vessels which surrounds the cornea and limbus resulting in visual loss. Limbal Stem Cell Deficiency is therefore a painful and blinding disease. It is difficult to manage at the best of times.
The complexity of biological system urgently demands computational models which can produce new understanding and new medicine. Keeping in view Khwarizmi Science society and Journal Club at IRCBM, COMSATS jointly presents a seminar on agent based modeling approach in Investigating Multiscale Tumorigenesis in the Warburg Effect.
Early stage tumorigenesis includes the formation of glycolytic cells in the tissue. However, the precise multi-scale processes underlying this transformation of healthy epithelial cells into tumorigenic glycolytic phenotypes, continues to be a matter of debate. In this work, we investigate this cellular transformation by using an agent based modeling approach and decode a multifactorial mechanism which upon triggering may lead to the onset of tumorigenesis
Nanotechnology is an interdisciplinary field which has brought marvels not only in solid-state device industry rather various bio-medical applications like gene sensing, DNA sequencing and bio-detection etc. owe a lot to this interdisciplinary research. It’s because of bio-nanotechnology that we are able to bring the sensitivity of current bio-sensing platforms down to the molecular level. This presentation will give you an overview of the techniques as well as the latest developments in the field of Bio-Nanotechnology. Both aspects of the presentation will be highlighted by examples of various nano-systems relevant for biomedical applications such as nanoparticle synthesis, formation of nanostructured surfaces, interaction of proteins as well as bio-membranes with drugs and insight into DNA and drug delivery systems.
