Requirement engineering is one of the most significant phases of software engineering. Success or failure of any software project relies heavily on better requirement engineering process. Better awareness of the requirements is fundamental for requirements engineering. Requirement Prioritization is an important component of requirement engineering process.(More)
Complete duplication of genitourinary system, colon and vertebral column is a very rare and complex congenital condition termed as "caudal duplication syndrome" with variable presentations. This term is often quoted as a type of incomplete separation of mono-ovular twins or conjoined twinning. It is associated with other congenital malformations of the(More)
BACKGROUND/AIMS The fate of intrahepatic NK cell subsets in the course of HCV and HBV infections is not clearly understood. METHODS Blood and intrahepatic CD56(+) NK cell subsets (expressing NKG2A, CD158a,h or CD158b,j receptors) from HCV or HBV patients were quantified by flow cytometry and localized by immunohistochemistry in liver biopsies. RESULTS A(More)
Hepatitis B and C viruses (HBV and HCV) cause chronic hepatitis and hepatocellular carcinoma (HCC) by poorly understood mechanisms. We show that cytokines lymphotoxin (LT) alpha and beta and their receptor (LTbetaR) are upregulated in HBV- or HCV-induced hepatitis and HCC. Liver-specific LTalphabeta expression in mice induces liver inflammation and HCC,(More)
BACKGROUND & AIMS In chronic hepatitis C (CHC), HCV-specific T-cell responses are often dysfunctionnal. In vitro data point out that regulatory T cells (Treg) are able to suppress HCV-specific lymphocyte proliferation and cytokine secretion but their implication in this pathology is still debated. METHODS Three complementary approaches were performed to(More)
The right requirements are considered as a part and parcel of software quality. Since the emergence of software engineering the perfect requirements have a deeper effect on the overall quality of software systems. This research paper is focusing on the shortcomings or limitations of existing software requirements prioritization techniques and paves the way(More)
