جرم وسزا کا اسلامی تصور: معاشرتی اثرات کا تجزیاتی مطالعہ

Islam provides a systematic system of crime and punishment through the Qur'an. The Qur'an first urges everyone to believe in Allah and the Last Day. And after that he commands piety. In the presence of which man's heart and mind remain free from sin. The Qur'an presents the concept of a society in which everyone meets his basic needs and desires in a legitimate way. And it does not have to resort to illegal and criminal means to meet these needs. When crime is not eliminated in these two ways, then the state orders the imposition of  sanctions. Islam is not limited to severe punishments. It calls for the establishment of a social system in which there is no room for crime. Even so, if a person commits a crime, the state punishes him as a warning. People can learn from these punishments and refrain from following the path of sin. The Qur'an also commands a group of Muslims to be present at the time of punishment.

Role of Hepatitis-C Virus Non Structural Proteins in the Induction of Insulin Resistance

Hepatitis C Virus is one of the lethal infections prevailing throughout the world. There are approximately 8.5 million individuals that are infected with this deadly virus in Pakistan. Hepatitis C virus is responsible for acute and chronic viral infection. Chronic hepatitis C virus infection causes persistent inflammation that leads to liver fibrosis, insulin resistance/type 2 diabetes mellitus, liver cirrhosis and finally hepatocellular carcinoma (HCC). There is strong evidence that insulin resistance has a major role in metabolic syndrome, and is a risk factor for increased liver fibrosis in patients with chronic hepatitis C virus infection. However the underlying mechanism of insulin resistance in chronic hepatitis C virus infection is not well known. The present study describes the molecular mechanism of HCV nonstructural protein 5A (NS5A) induced insulin resistance. In this study, we elucidated the molecular mechanism involved in HCV nonstructural protein 5A (NS5A) induced insulin resistance. In the present study human hepatoma cell line Huh 7.5 was transfected with HCV NS5A (Huh 7.5/NS5A) as well as HCV (JFH-1) genomic RNA was transfected into Huh 7.5 cell line (Huh 7.5/HCV) to discern the effect of HCV and HCV NS5A protein upon modulation of insulin signaling pathway. Here, we demonstrated that an increased serine phosphorylation of insulin receptor substrate-1 (pSer307) and Akt (pSer473) in Huh 7.5/HCV infected cells compared to mock infected cells. Interestingly, the Huh 7.5/NS5A cell line showed an increased serine phosphorylation of pSer307 IRS-1 and pSer473 Akt, compared to the mock transfected cells, which is a critical step defining the downstream insulin signaling pathway. Glycogen synthase kinase-3 (GSK-3), the downstream target of Akt, is known to favor gluconeogenesis. Our results revealed a diminished phosphorylation level of GSK-3 in Huh 7.5/NS5A expressing hepatoma cells compared to the mock transfected cells, thereby favoring gluconeogenesis. Forkhead transcription factor (FOX-01) which is another important downstream target of insulin signaling pathway, was shown to undergo reduced phosphorylation level (pSer 256) in Huh 7.5/NS5A expressing hepatoma cells compared to the mock transfected cells. Collectively, these findings suggest a molecular mechanism by which ectopic expression of Huh 7.5/NS5A modulates the insulin signaling pathway at post translational level. There are several gluconeogenic and lipogenic markers lying downstream to the insulin mediated signaling molecules (pSer307IRS-1, pSer473Akt, pSer256Fox-01 and GSK-3). In this study, we observed that Huh 7.5/HCV infected hepatoma cells as well as ectopic expression of Huh 7.5/NS5A leads to enhanced gluconeogenesis through up regulating the mRNA levels of gluconeogenic genes i.e. Phosphoenol pyruvate carboxy kinase (PEPCK) and Glucose-6-phosphatase (G6P) compared to their controls. In the similar way, an elevated mRNA level of Diacyl glycerol acyltransferase (DGAT), a key lipogenic marker, was also observed in Huh 7.5/HCV infected as well as Huh 7.5/NS5A expressing hepatoma cells compared to their controls. Based on these results, we deduce a mechanism through which HCV NS5A is potentially capable of modulating the entire insulin signaling pathway at mRNA and post-translational level thereby paving a way towards insulin resistance, a metabolic syndrome.
