Abstract: 

How cell fates are established and how identities of different cell types are maintained during development of multi-cellular eukaryotes are questions of extreme biological significance at the heart of development. A single-celled zygote undergoes many rounds of mitotic divisions which ultimately lead to generation of over 200 different specialized cell types in human body during development. Although, each cell type contains same basic genetic information (DNA), yet their identity is different from one another which are maintained throughout development. It is known that differential gene expression programs lead to different cell lineages and each cell type remembers its identity due to maintenance of cell type specific gene expression program referred to as transcriptional cellular memory. Transcriptional memory involves changes in the chromatin state of lineage specific genes; changes that can persist through DNA replication and mitosis, which means they are inherited from mother to daughter cells. Such heritable changes are called epigenetic modifications and can be covalent marks on DNA and/or histones, and therefore would not alter the basic genetic information in a cell. However, epigenetic changes may either activate or silence the expression of lineage specific genes and set the stage for differential gene expression among different cell type. This explains how cells with same DNA can acquire different identity which is maintained through epigenetic inheritance during development. In Drosophila melanogaster (fruit flies), genetic analyses have uncovered two groups of genes, the Polycomb Group (PcG) and the trithorax Group (trxG), responsible for maintaining gene expression patterns stably and heritably. Importantly, PcG and trxG proteins are evolutionary conserved and most of our knowledge about their function was pioneered from studies in Drosophila. Molecular analysis showed that many of the proteins encoded by the PcG and trxG act in large complexes, and modify the local properties of chromatin to maintain transcriptional repression (PcG) or activation (TrxG) of their target genes. My lecture will primarily focus on introducing epigenetics, transcriptional cellular memory and how they affect our development.

High Energy Astrophysics and the Origin of Cosmic Rays

Registration: 
Registration is required.
Date: 
21 May, 2010
Time: 
10 am
Venue: 
Institute of Biochemistry and Biotechnology, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

The origin of Galactic cosmic-ray ions has remained an enigma for almost a century. Although it has generally been thought that they are accelerated in the shock waves associated with powerful supernova explosions—for which there have been recent claims of evidence—the mystery is far from resolved. Cosmic rays, which are mostly protons, but also other ions and electrons, permeate our Galaxy and rain down on earth continuously, night and day. Although cosmic rays were discovered almost a century ago, back in the balloon age, their origins remain unclear even now. Almost no effort has been spared in pursuing this long-standing mystery: satellites, rockets and balloons have been launched, and enormous detector arrays have been installed on the ground and even under mountains and seas. I will give a historical overview of the search for the mysterious origin of cosmic rays and a report on the current status.

Abstract: 

Lasers from Islamabad, Lahore and Cern: What Binds them Together (Dr. Shaukat Hameed Khan)

The laser is just 50 years old but it is shaping our lives in diverse manners. One key area is precision of measurement. A small Pakistani innovation to the design of the system which makes up the massive detectors in the Large Hadron Collidor at CERN in Geneva is discussed. This is placed in the context of mankind’s greater quest over the centuries for precision, whether these relate to his position on earth or in space, or timekeeping.  The principal features of the laser programme in Pakistan is presented briefly.

Laser-generated Pulsed X-ray Sources (Dr. Fida Khattak)

I would be presenting the basic principles of x-ray generation via different schemes using high power laser pulses for the non-specialized. I would be also presenting some experimental results for the audience having research interest in the field.

Fundamentals of Fiber-optic Communications (Dr. Mumtaz Sheikh)

Ever since the advent of the internet, fiber optic communication systems play an important role in our everyday lives. This talk would  focus on how do these systems work, what is so special about them compared to traditional electrical communication systems, what kind of
lasers are suitable for such systems, what are some of the issues and tradeoffs that a designer has to consider while designing such systems and where is the technology headed in the future.

Light: Its Applications in Interferometery, Polarimetry and Photodynamic Therapy (Dr. Masroor Ikram)

Light is one of the oldest subject but its true nature has yet to be fully discovered. For more than hundred years its dual nature is well accepted. Optics and Laser Group in PIEAS has worked on some of its applications. Michelson interferometer was reported in the late nineteenth century but its use for precise measurement of angle and axis of rotation is reported very recently. Polarization imaging can produce very high contrast and the technique is useful for material characterization. Photodynamic therapy is an emerging technique to cure the cancers with high selectivity. In the technique, two individually non-toxic components brought together to cause harmful effects on cells and tissues in the presence of oxygen.
