The genetic diversity among globally circulating human immunodeficiency virus type 1 (HIV-1) strains is a serious challenge for HIV-1 vaccine design. We have generated a synthetic groupMconsensus env gene (CON6) for induction of cross-subtype immune responses and report here a comparative study of T-cell responses to this and natural strain env immunogens in a murine model. Three different strains of mice were immunized with CON6 as well as subtype A, B, or C env immunogens, using a DNA prime-recombinant vaccinia virus boost strategy. T-cell epitopes were mapped by gamma interferon enzyme-linked immunospot analysis using five overlapping Env peptide sets from …

A compound and method for using the compound to reduce injury associated with ischemia and reperfusion of mammalian organs such as the heart. The compound, either Deltorphin A and/or Dermorphin H, may be administered as part of a preconditioning strategy which reduces the extent of injury and improves organ function following cessation and restoration of blood flow. The compound may be used in preparation for planned ischemia or in a prophylactic manner in anticipation of further ischemic events.

Abstract Metaplastic carcinoma breast is categorized as a rare heterogenous neoplasm generally characterized by a mixtureof adenocarcinoma with dominant areas of spindle cell, squamous and/or other mesenchymal differentiation. Todetermine the epidemio-demographic and histopathologic characteristics of this rare entity a retrospective studywas conducted to review all cases at the Aga Khan University Hospital (AKUH) Karachi, received during 1st January2000 to 31st August 2005. Twenty-four patients were identified with a mean age at diagnosis of 46.4 (±SD 3.8) years,and an age range of 28-68 years. The mean tumor size was 7.9 cm, range 2.0–17.0 cms (±SD 4.77). The specimenswere mostly obtained by …

Abstract The objective of this study was to determine the frequency of phylloides tumor (PT) in adolescent girls and youngwomen (less than and equal to 25 years of age) and to define the clinico-pathological features of PT in this unusualclinical setting. This descriptive study was carried out at the Aga Khan University Hospital (AKUH) pathologydepartment. All consecutive cases of PT diagnosed during the last sixteen years in the section of histopathology from1st January 1990 to 31st June 2005 were included. Selection of cases was restricted to patients up to 25 years of age.A total of 42 cases of PT in …

No Vaccine Against Hiv Yet--Are We Not Perfectly Equipped?, Mahender Singh

Enormous effort has been devoted to the development of a vaccine against human immunodeficiency virus (HIV). But it is proving to be an unprecedented challenge to create an effective vaccine mainly due to the high genetic variability of the virus and the necessity of cytotoxic T lymphocytes (CTL) for containing the infection. Currently pursued vaccine strategies appear to induce CTL in nonhuman primate models but in the early clinical trials, these strategies fail to fully control the viral infection. New strategies that can cover the vast genetic diversity of HIV are needed for the development of a potent vaccine.

HIV-1 subtype C is the most common HIV-1 group M subtype in Africa and many parts of Asia. However, to date HIV-1 vaccine candidate immunogens have not induced potent and broadly neutralizing antibodies against subtype C primary isolates. We have used a centralized gene strategy to address HIV-1 diversity, and generated a group M consensus envelope gene with shortened consensus variable loops (CON-S) for comparative studies with wildtype (WT) Env immunogens. Our results indicate that the consensus HIV-1 group M CON-S Env elicited cross-subtype neutralizing antibodies of similar or greater breadth and titer than the WT Envs tested, indicating the …
