Joux [10] presented a one round protocol for tripartitie key agreement and Al-Riyami et.al. [15] developed a number of tripartitie, one round, authenticated protocols related to MTI and MQV protocols. Recently, Boneh and Sil-verleg [4] studied multilinear forms, which provides a one round multi-party key agreement protocol. In this paper, we propose (n + 1)(More)
We give a simple proof of existence of solutions of the dispersion management and diffraction management equations for zero average dispersion, respectively diffraction. These solutions are found as maximizers of non-linear and non-local vari-ational problems which are invariant under a large non-compact group. Our proof of existence of maximizer is rather(More)
The effects of processed Aloe vera gel (PAG) on the course of established diet-induced non-insulin-dependent diabetes mellitus (NIDDM) were studied in C57BL/6J mice. NIDDM was induced in C57BL/6J mice by feeding them a high-fat diet. Mice exhibiting diet-induced obesity (DIO) with blood glucose levels above 180mg/dl were selected to examine the antidiabetic(More)
The gels of Aloe species contain immunomodulatory components such as aloctin A and acemannan. Most studies on these gels were performed in in vitro cell culture systems. Although several studies examined their immunomodulatory activity in vivo, the route of administration was intraperitoneal or intramuscular. Here, we evaluated the in vivo immunomodulatory(More)
The main targets for the immunosuppressive calcineurin inhibitors, cyclosporin A (CsA) and tacrolimus, have been considered to be activated T cells, but not antigen-presenting cells. Here we demonstrate that CsA and tacrolimus, but not rapamycin, inhibit major histocompatibility complex (MHC)-restricted antigen presentation in dendritic cells (DCs).(More)
PURPOSE Epitope-based cancer vaccines capable of inducing CD8 T-cell responses to tumor-associated antigens (TAA) expressed by tumor cells have been considered as attractive alternatives for the treatment of some types of cancer. However, reliable TAAs have not been identified for most malignant diseases, limiting the development of epitope-based vaccines.(More)
Myeloid-derived suppressor cells (MDSCs) mediate tumor-associated immune suppression in both cancer patients and tumor-bearing animals. Reduction or elimination of MDSCs reduces the rate of tumor progression and improves cancer therapies that employ mechanisms of immunity. Here we show that baccatin III, which is the precursor for the semisynthesis of(More)
