الالتفات في القرآن الكريم دراسة تحليلية

The paper deals with the different styles  of iltifāt  found in the Holy Qur’ān  and coming out with a general scheme to account for its occurrence in order to enhance the understanding of the subtleties of this feature of Qur’ān ic style. To accomplish this, the research was carried out by way of an analytical study of the instances of iltifāt  in the Holy Qur’ān. As a prelude to the discussion of this subject, the research provides the meaning of iltifāt  among the Arab rhetoricians and the status of iltifāt  as one of the rhetorical tropes. The paper also discussed the significations of iltifāt  which have already been mentioned by previous scholars, and since those scholars touched on the significations only briefly, therefore, the research strived to explore further aspects of their interpretations making an effort to highlight new significations of iltifat and an attempt to introduce a new approach in looking at the iltifāt  phenomenon, in different Sura’hs of          Qur’ān, to demonstrate the application of this new perspective. Finally the research shows that the occurrence of iltifÉt in the Qur’ān  follows certain patterns that are related to the intended significations at the various locations where they appear in the Qur’ān.

Mutational Analysis of Complete Coding Sequence of Toll Like Receptor-2 Gene in Dhani and Jersey Cattle Breeds of Pakistan

The current research work focus on disease resistance and susceptibility studies in livestock animals have been on determining patterns of key proteins in the innate immune response, such as toll-like receptor 2 (TLR-2) gene primary role in the recognition of pathogen associated molecular pattern (PAMP) from bacterial ligands. To date, ten members of TLRs family have been identified in cattle. The objective of the present study was to detect polymorphisms in the genomic sequences of TLR-2 gene in two important cattle breeds Bhagnari and locally adapted exotic Freisian. Phylogenetic analysis was carried out based on complete coding sequences of TLR-2 gene to describe the relationship between the breeds. Mutations in coding sequences of TLR2 gene in Dhani and Jersey were studied. The complete coding sequence of TLR2 gene consists of 2355 base pair [bp] was determined. The amino acid [aa] sequence of the coding region corresponds to a protein of 784 amino acids long with predicted molecular weight 104 kDa and 6.97 pI value. The amino acid sequence analysis showed extracellular domain composed of leucine rich repeats (LRR), trans- membrane domain and Toll-IL receptor domain in the protein. Nucleotide sequences of TLR2 gene in Dhani cattle breed revealed a total of 35 polymorphisms. In the analysis 66% polymorphisms were synonymous caused no changes in protein and 34% were non-synonyms. Overall 20 polymorphisms were observed in Extracellular domain, five variants in trans-membrane, three polymorphisms in unknown region and seven mutations in TLR domain were detected. In Jersey cattle breed, a total of 21 polymorphisms were detected, in which 52% were synonymous and 48% were non-synonymous. Protein analysis showed that 15 mutations were observed in region specifying the Extracellular domain, three in Trans-membrane domain and three polymorphisms in TLR domain. The finding of this research revealed that detected polymorphisms may be associated with PAMPs mediated di?erential TLR signaling of bovine immunity and could determine the outcome of infection.
