Abstract: 

This talk will take you for a quick walk through the Universe. Todays universe as we know it, is indeed dusty. More than 30% of the UV and optical light from stars in the Universe may be absorbed and re-radiated thermally at infrared and millimeter wavelengths by the obscuring dust. The cool and dusty sites in the Universe provide seeds for the formation of molecules and organic compounds. These molecular clouds are actually stellar nurseries which give rise to star formation and its evolution. To study dust extinction and its properties, Gamma-ray burst after-glows are excellent probes. This topic will cover that what we know about dust and how do we study it.

Reconstruction of the Corneal Surface using Stem Cell Biology

Registration: 
Open to all.
Date: 
22 July, 2013
Time: 
10 am
Venue: 
IRCBM, COMSATS Institute of Information Technology, Raiwind Road, Lahore.
Abstract: 

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.

 

Dr. Sajad Ahmad has developed an animal free culture method for limbal stem cells that has been used to successfully regenerate the corneal epithelium in patients with unilateral chemical burns and restore their vision. He is currently collaborating with centres in Edinburgh (UK), Oslo (Norway), Harvard University (Boston, USA) and Dublin (Ireland) to develop this technique in those centers for future mulitcenter clinical trials. He will outline this method. He was also the first to differentiate human embryonic stem cells into the corneal epithelial lineage and he will discuss this approach and the opportunities this presents.

High Energy Astrophysics and the Origin of Cosmic Rays

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.

Understanding Cell Matrix Interactions

From Fundamental Thermodynamics to Applications in Tumor Metastasis
Registration: 
Open to all.
Date:

Time: 
11:00 am
Venue: 
Institute of Biochemistry and Biotechnology, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

Cells reside and operate in a complex and dynamic extra-cellular matrix. The mechanical, structural and chemical properties of the matrix regulate a variety of cellular functions including signaling, adhesion, migration as well as invasion and metastasis in tumor systems. Unfortunately cell-matrix interactions have traditionally been studied in the context of artificial 2D environments, which are far from in vivo conditions. As a result, our understanding of the complex interactions at the cell-matrix interface has been quite limited. In particular, the mechano-chemical effects of the matrix, the proteolytic pathways and surface receptor dynamics on a 3D surface that are critical in invasion and tumor metastasis, and can not be fully studied in a 2D environment. In order to overcome the limited powers of observation in 2D, we utilize a combination of high resolution and high throughput confocal microscopy, bulk and micro-rheological measurements and multi-scale simulations rooted in statistical and continuum mechanics. Using an interdisciplinary approach allows us to understand and quantify the mechanical and chemical roles of the matrix in regulating signaling, adhesion and motility. Our results demonstrate that both cell structure and cell function are strikingly different in 3D than in 2D and that cellular response to minor mechanical changes in its extra-cellular environment is amplified in 3D than in 2D environments. Our experimental results are complemented by multi-scale simulations, that probe the physical foundations of cell-matrix interactions from the nano to the macro level. Our hybrid approach, combining high-resolution experimental and computational techniques demonstrates how a balance of cellular parameters (e.g. integrin expression and MMP activity) co-operate with matrix properties (e.g. composition, stiffness and porosity) to regulate adhesion, invasion and motility of tumor cells in native like environments.

Biomaterials for Tissue Engineering

Registration: 
Open to all.
Date: 
24 January 2008
Time: 
11:00 am
Venue: 
School of Biological Sciences, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

Biomaterials are defined as materials that are used in medical devices or are in contact with biological systems. Their application can range from skeletal systems (bone implants, knee joints, dental implants etc), cardiovascular systems (stents, catheter, heart valve etc), organs (artificial kidney, heart lung machine, skin etc) and senses (contact lens, corneal bandage etc). The field of biomaterials uses ideas from medicine, biology, physics, chemistry, materials sciences, engineering, ethics, law and health care. Biomaterials are usually integrated into devices or implants hence the interdisciplinary aspect is important for progress. The field brings together researchers from diverse academic backgrounds. They must communicate clearly. Some disciplines that intersect in the development, study and application of biomaterials include: bioengineer, chemist, chemical engineer, electrical engineer, mechanical engineer, materials scientist, biologist, microbiologist, physician, veterinarian, ethicist, nurse, lawyer, regulatory specialist and venture capitalist. Biomaterials can be metals, ceramics, polymers, glasses, carbons, and composite materials. Such materials are used as molded or machined parts, coatings, fibers, films, foams and fabrics. One of the major applications of biomaterials is in the field of tissue engineering. This field combines the knowledge of engineering, life sciences and clinical practice to solve the problem of tissue loss or damage, aimed at facilitating the regeneration of damaged or diseased tissue. The essence of tissue engineering is the use of living cells, together with degradable scaffolds and growth factors in development of implantable parts or devices for the restoration of body function. A major component in the revolutionary field of tissue engineering is the development of the suitable scaffold for seeding cells, growth factors and subsequent growth of tissues. There has been a considerable effort devoted to improving material and biological properties of scaffolds used in bone tissue engineering during the past decade. We developed and investigated different porous scaffolds with improved material properties and biological functions. An introduction to various scaffold materials developed in the lab along with future challenges will be presented towards the end.
