About me

After obtaining an M.Sc. in Biochemistry from the University of Peshawar, I worked as a Scientific Officer at the National Institute of Health, Islamabad, Pakistan. I then proceeded to USA to work towards my Ph.D in the Department of Biochemistry & Molecular Biology, University of North Texas, Denton, Texas, USA.

During my stay in the US I worked as a Research Assistant at the Department of Biochemistry, University of North Texas and as a Research Associate at the Department of Microbiology & Immunology, Texas College of Osteopathic Medicine, Fort Worth, Texas, USA. After completing my Ph.D. I came back to Pakistan and joined Dr. A. Q. Khan Research Laboratories as a Senior Scientific Officer and was subsequently promoted to the position of Principal Scientific Officer. From 1998 to 2001 I worked for a while, with Dr. Chris Tyler-Smith at the Department of Biochemistry, University of Oxford, Oxford, UK in the lab of Prof. E.M. Southern. In 2002 I joined Shifa College of Medicine as Assistant Professor of Biochemistry and in 2003 was promoted to the post of Associate Professor & also appointed as the Director of PCR Labs. .....Read more

“Ophthalmogenetic Screening of Pakistani Patients”.

Prof. Dr. Raheel Qamar.

Latest article added on March 05, 2014

In the year 2005 the lab of Prof. Dr. Raheel Qamar, T.I. started working on Ophthalmogenetics of Pakistani patients with emphasis on the screening of monogenic and multifactorial eye diseases. Since then the lab has been conducting genetic analysis of non-syndromic and syndromic retinal dystrophies, glaucoma, age related macular degeneration, keratoconus and diabetic retinopathy in Pakistani patients.

“Huanglongbing (Citrus Greening) A Major Threat to Citrus in Pakistan”.

Chohan, S., Holford, P., Beattie, A., Ahmad I., Ullah, F. and Qamar, R.

Latest article added on July 11, 2007

Introduction - Citrus decline: Citrus decline has been recognised in Pakistan for decades and adversely affects the general health of plants. The problem is widespread and is variously attributed to edaphic factors such as heavy clay soils, high water tables and inadequate drainage, deficiencies in trace elements or deleterious actions of a range of fungal pathogens or nematodes. While these causes of decline do affects citrus orchards in Pakistan, it is likely that the main cause of decline is due to a bacterial disease called huanglongbing (HLB), more commonly referred to as citrus greeting in Pakistan.

Bioinformatics ? Studying Genes Using Computers

Prof. Dr. Shahid Nadeem Chohan
Prof. Dr. Raheel Qamar

Introduction - Curiosity is an exciting part of human psyche. We are curious about our surroundings as well as ourselves. We want to know what, how and why things are as they are and how can we either use them as such or change them to our advantage. We have been doing this from the beginning of our evolutionary history  and keep doing it over our personal life spans. Consequently, this curiosity has led to a tremendous wealth of knowledge. This huge knowledge base has generally been organized in such a way that it potentially can readily be accessed, verified and used. All this organized body of knowledge is collectively called science. Science has several subdivisions; the physical sciences deal with our physical environment and the Biological sciences deal with all life forms including ourselves. While Biology encompasses all sciences dealing with life and its interaction with the environment, Molecular Biology is the study of life at a molecular level. HEC News Letter

Bird Flu

Prof. Dr. Raheel Qamar

Origin and spread among birds.

The Bird Flu virus was first identified in Italy in the 1900s and has subsequently been shown to be endemic worldwide in the bird populations.  The birds carry the virus in their intestines and these infected birds then shed the virus in their saliva, nasal secretions and feces.  Unaffected birds become infected when they come in contact with secretions or excretions from the affected birds or come in contact with surfaces that have been contaminated with the secretions and excretions of the infected birds.  The mode of transmission from one region to another is via wild migratory water fowl like ducks, geese and swans.  These water fowl transmit the virus to the poultry of an unaffected country by their droppings which contaminate either the water and food sources or surfaces with which the unaffected poultry comes in contact.  Pakistan is on the migratory flight path of these water fowl — these birds spend summers in Siberia and they winter in Afghanistan, Pakistan, Iran and India.  Since these other countries have demonstrated clearly the presence of the H5N1 viral subtypes so it is inconceivable that Pakistan does not have the virus in its poultry populations.

Introduction To The Polymerase Chain Reaction (Pcr) Technique

Prof. Dr. Raheel Qamar

Before the introduction of the Polymerase Chain Reaction (PCR) technique the traditional techniques of Molecular Biology that were being used for the identification and characterization of DNA fragments, were quite cumbersome and required considerable skill for the successful execution of an experiment.  This is particularly true in cases where a high level of specificity and sensitivity is required, e.g. the Southern Blotting technique, introduced by Edwin Southern in 1975, fails to distinguish between pseudo-genes and the actual gene in a multi-gene family and using this technique it is also difficult to detect single copy genes.

Applications Of The Polymerase Chain Reaction (Pcr) Technique And Instrumentation

Prof. Dr. Raheel Qamar

The Polymerase Chain Reaction (PCR) technique has had a significant impact in the field of medical genetics, it not only allows a qualitative analysis of pathogenic organisms, but also is an excellent tool to determine the viral or bacterial load of a patient.  Besides this the genotype of an organism can also be determined reliably and thus one does not have to rely on indirect methods of determining the genotypes such as serotyping.
