Type of Research Project
- Clinical Project with Laboratory work
What is the background of the project?
In many cases of rape, the biological materials are recovered after examination of the victim or may be submitted after long time for DNA analysis or may be lying pending for DNA analysis. Therefore, the present work was taken up to study the effect of storage conditions and yield of DNA from different textures of cloth for seminal stains, the biological material forwarded in rape cases. The seminal stains recovered on fabrics are one of the most important evidence in rape cases. Stained clothing’s, undergarments and swab’s on fabric material taken from vagina and surrounding regions, are submitted for DNA Fingerprinting test to compare it with the blood sample of the accused person.
What is the aim of the project?
The aim of this work is to evaluate the effect of different factors on extraction of blood and seminal stain DNA from clothes.
What techniques and methods are used?
This study includes DNA extraction, PCR detection of antigens, electrophoresis
What is the role of the student?
- The student will mainly observe
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- The tasks will be done under supervision
- If the project includes “lab work”
- the student will take active part in the practical aspect of the project
- If the project is clinical
- the student will be allowed to work with patients
- The tasks of the student will be performed on his/her own
What are the tasks expected to be accomplished by the student?
Observation of extraction of DNA of blood and seminal stains from clothes and exposing them it different environmental factors such as cold, heat burn, alkali, corrosives and observing their effect on The DNA profiling visualization by spectrophometry, bioanalyzer, and finally profiling by PCR, also data analysis and results comprehension are expected to be done under supervision of the professor first, then done on the student’s own, and the professor will review and discuss the results with them at the end.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Lectures conecring the topic; presentation of the clinical skills used.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a scientific report
- The student will prepare a poster
- The student will prepare a presentation
- The student will prepare an abstract
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
It's preferred if the student have studied Forensic Medicine.
Are there any legal limitations in the student’s involvement
