A Study On Prevalance Of Hcv Genotypes And Risk Factors Of Hepatitis C Virus In Punjab

by Tahira Tarar | Miss Faiza Masood | Dr. Muhammad | Mr. Zahid Mushtaq.

Material type: book Book; Format: print Publisher: 2011Dissertation note: Hepatitis C virus (HCV) was marked as major agent which causes non-A, non-B hepatitis. Various partial and complete sequences of HCV nucleotide had been identified in the world. When these sequences were compared a marked genetic heterogeneity was revealed, that suggested the existence of HCV genotypes. Recent studies have pointed out the association of different HCV genotypes with different profiles of pathogenecity, infectivity and response to antiviral therapy. In our study we used typing system based on genotype specific primers focused on HCV 5´-UTR by using PCR. Genotype specific primers were designed for genotype 1, 2a, 2b, 3a, 3b and 4. 100 samples of HCV positive patients were collected. The frequency of occurrence of genotype 2a was 4 %, 2b was 5 %, 3a was 71 %, 3b was 11% and untypeable was 9 %. Blood transfusions, therapeutic injections, reuse of needles, dental procedures, shaving practices, body piercings, jaundice, dialysis, surgery and other multiple risk factors associated with HCV were studied. Major risk factor among females was therapeutic injections and among males the major risk factor was absence of shaving precautions. The study concludes that the most prevalent genotype in Punjab province is 3a. As each genotype sequence is different, the antiviral therapy against that particular genotype is also different. The treatment would only be successful if the genotype of HCV infected patient is known. This study will help in correlating efficacy of interferon therapy with different HCV genotypes and to understand the mode of transmission for hepatitis C virus.

Evaluation Of Pouifi As Candidate Gene To Have Influence On Milk Production In Red Sindhi And Dhani Cattle Through SNP Detection

by Waqas Tahir | Prof.Dr.Masroor Elahi Babar | Dr. Atif Hanif | Mr. Zahid Mushtaq.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2011Dissertation note: There are more than 200 million cattle in Pakistan which are a source of milk, meat, hide and drought purpose. Due to this large population of cattle, Pakistan is the fourth largest milk producer in the world. In spite of large number of cattle population in Pakistan, per animal milk production is yet quite low. That's why it is not wrong to say that there is still a great potential in the dairy sector of Pakistan to improve the overall milk production by improving the per animal Jilk production. This can be only achieved by improving the genetics of the dairy animals in Pakistan besides the other factors as well. Milk production is a polygenic trait. It is well established that growth hormone (GH) released from pituitary gland also plays an essential role' in growth, mammary gland development and lactation process. POUIFI factor is a member of the POU family of transcription factors that regulate animal growth and development and is also involved in the development of pituitary and regulation of hormonal expressions in animals. Therefore, genetic variation in the POU1Fl gene and its associations with growth traits in livestock animals could provide useful genetic markers for animal selection and breeding through marker-assisted selection (MAS). This study was conducted to genetically characterize !he POUIFI gene to identify the SNPs as genetic markers for future breeding and selection ~Ians. Keeping in view the importance of this gene all introns and axons were sequenced in smples of Red sindhi and Dhanni cattle to identify the SNP and validate the potential markers There are more than 200 million cattle in Pakistan which are a source of milk, meat, hide and drought purpose.
