تحدت للعالم الإسلامي ودور الشباب في مواجهتها

Youth are the real asset of a nation, nation make progress by channelizing, the energy and effects of youth in the right direction. If youth of a nation go astray, the nation will be bound to fail. This short paper intends to look at the challenges faced by our youth for example, the political, religious and philosophical influence of anti-Islam powers, the use of all resources to attract youth to Islam, the attraction of Muslim youth to philosophy, to look into the influence of west through education which is leading the nation to financial and social way wardenss Indecency, Arabic language is replaced with other language for teaching and understanding of the Qur’ān and Unemployment, poverty and a sense of uselessness of youth is a huge challenge. This factor is leading the youth to stealing, robbery and other moral weaknesses. This short article will try to throw light on the challenges and responsibilities of youth. The history of mankind tells us that it is only the young people, who took the revolutionary measures to change the societies. Youth is the prime time of ones life. It is the time when all energies are at their peak. So one should get advantage of youth before getting old and helth before falling sick. As they say “new broom sweap clean”. Young people can bring great changes in cleaning socieities from evils. Muslim youth has great resficial to whole humanity. Today, youth is facing many challenges in their life. These challenges are in social, moral, educational, intellectual and political fields. To cope with them youth must have the knowledge and awareness. This short article tends to throw light on these challenges and gives ways and remedies to face them successfully.

Mapping of New Locus in Deafness

Deafness is the most prevalent disorder with 1 in every 500 of world population has disabled hearing loss. Deafness may occur in non-syndromic or syndromic form. Non-syndromic deafness accounts for 70% while remaining 30% accounts for syndromic deafness. Although deafness is prevalent worldwide but determination of causative genes is difficult due to genetic heterogeneity and limited genotype phenotype correlation of deafness related genes. An extensive research on deafness in the last two decades has paved remarkable progress in the detection of deafness related genes. In terms of nonsyndromic recessive hearing loss, the chromosomal locations are presently identified for ~102 loci recessive deafness, elucidating role of 63 genes having causative role in deafness. As nearly 300 genes are involved in hearing cascade a need of further study is the requirement for current study of deafness genetically. The present study was intended to ascertain the molecular basis of deafness expressed at different audiometric levels by making use of linkage analysis as a genetic tool. To attain the objective, Thirty five families with non-syndromic and syndromic phenotype segregating with autosomal recessive mode of inheritance were enrolled, after collection of blood samples DNA was extracted and linkage analysis was done for already reported autosomal recessive deafness loci. In eleven families having syndromic phenotype, four families showed linkage to Usher Syndrome Type 1D, three families showed linkage to Usher Syndrome Type 1F and one family was found linked to Usher Syndrome Type 2C whereas remaining three were found linked to DFNB4/PDS locus. All three Pendred syndrome linked families showed similar pattern of haplotype with DFNB4 Short Tandem Repeats markers. Interestingly on mutational analysis p.Y556C mutation was found in all affected individuals this finding outline this mutation as founder mutation in Punjabi ethnicity of Pakistani population mutation spectrum. In Five families with non- syndromic phenotype, one family was found linked to DFNB49 locus whereas four families were found linked to DFNB8/10, DFNB4, DFNB21 and DFNB7/11 loci. Sequence analysis of these linked families identified two reported mutations one c.1219T>C; p.C407R in TMPRSS3 gene (DFNB8/10) and other c.71G>T; p.R24L in SLC26A4 gene (DFNB4) whereas one novel mutation c.1247_1248delGG; p.G416Dfs*24 in TECTA gene (DFNB21) and a novel compound heterozygous mutation c.1259G>A; p.C420Y and c.1788C>A; p.S596R in TMC1 gene (DFNB7/11) was found. The genome scan of the family PKDF1629 having syndromic phenotype outlines a new recessive deafness locus hint at chromosome 6 position q23.3-25.2 with a critical linkage interval of 19.2Mb. This novel discovery will assist in better understanding of genetics involved in syndrome associated with deafness and will pave way for their diagnosis, treatment and eventually their control.
