10556 Background: Dendritic cells (DC) play a key role in the development of tumor specific immune responses. Dendritic cells differentiated from leukemic blasts (LDC) are being explored as a tumor vaccine in AML. We examined the phenotypic and functional characteristics of LDC, the phenotypic characteristics of native DC in AML patients, and the effect of leukemic blasts on the phenotype of DC generated from normal donors. Methods: Leukemia blasts were isolated from peripheral blood of 24 patients with AML. LDC were generated by culturing blasts in the presence of GM-CSF, IL-4 and TNFa for 7

Dendritic cells (DC), in general, and pulmonary DC, in particular, are a heterogeneous population of cells, their phenotype and function being dependent on their anatomic location, their state of activation, and the regulatory effect of locally secreted cytokines.

Abstract:

Abstract Adoptive immunotherapy of leukemia aims at eradicating the disease through the transfer of leukemia-reactive lymphocytes. Donor lymphocytes infusions (DLI) after allogeneic hemopoietic cell transplantation (allo-HCT) have shown to cure chronic myelogenous leukemia (CML). Unfortunately, when applied to acute leukemias, the DLI approach is far less successful. Strategies to increase the efficacy of adoptive immunotherapy for the cure of acute leukemias are therefore urgently needed. To this aim, blasts from acute myeloid leukemias (AML) can be differentiated in vitro into dendritic cell

Abstract Abstract 4090 Poster Board III-1025 Allogeneic hematopoietic transplantation (allo-HCT) is the only curative option for patients affected by high-risk acute myeloid leukemia (AML). This is largely due to the ability of allogeneic immune system to eradicate leukemic stem cells (LSC). However, the fact that some patients still relapse after allo-HCT, suggests that strategies to increase LSC targeting by donor T cells are needed. For this purpose, we exploited the unique ability of myeloid blasts to differentiate into leukemic dendritic cells (LDC). We observed that a short (48h) exposur

The switching frequency of the proposed converter is fixed at 1 MHz to achieve a constant frequency operation for the resonant converter.

In this water cooling method, controlling the flow rate of water is critical for uniform cooling of the component.

Abstract:

    Power suplai DC merupakan suatu rangkaian elektronika yang mengubah arus listrik bolak balik (AC) nenjadi arus listrik searah (DC) yang digunakan untuk mensuplai tegangan. Dalam pembuatan rangkaian power suplai DC, dibutuhkan komponen elektronika yang terdiri dari transformator, rectifier, filetering dan IC sebagai regulator tegangan. Agar menghasilkan tegangan yang konstan, digunakan IC dengan series 78XX, dan untuk menghasilkan tegangan variabel digunakan IC LM338. Mikrokontroller digunakan sebagai pengubah nilai analog keluaran power suplai DC menjadi digital yan

Abstract:

The line-commutated converter (LCC)-based high voltage direct current (HVDC) technology has been widely applied on long-distance and bulk-capacity power transmission occasions. Due to the terrible interferences in the vicinity of communication lines, DC filters (DCFs) are always installed to mitigate the interferences within acceptable levels for almost all in-service overhead line transmission LCC-HVDC schemes. With the rapid development of the communication technology, however, the anti-interference capability of the telephone system has been remarkably improved. Thus, the original purpose o

Abstract:

A selective fault clearing scheme is proposed for a hybrid voltage source converter (VSC)-line commutated converter (LCC) multi-terminal high voltage direct current (HVdc) transmission structure in which two small capacity VSC stations tap into the main transmission line of a high capacity LCC-HVdc link. The use of dc circuit breakers (dc CBs) on the branches connecting to VSCs at the tapping points is explored to minimize the impact of tapping on the reliability of the main LCC link. This arrangement allows clearing of temporary faults on the main LCC line as usual by force retardation of the

Abstract:

In response to the existing issues of poor anti-offset performance and insufficient width of the matchable voltage range at the DC end in the current bidirectional wireless power transfer (BWPT) system for electric vehicles, an efficient wireless bidirectional charging and discharging system for electric vehicles based on the LCC-S compensation network is proposed. Compared with the topological structure of the traditional two-stage wireless bidirectional charging and discharging system, this system adds a DC-DC module in the on-board equipment, while the BWPT link adopts the LCC-S compensatio

Conjugated linoleic acid (CLA) have been shown to exert numerous health benefits, including anti-carcinogenic, anti-atherogenic, anti-diabetic, antiobesity, cholesterol reducing, antioxidant, anti-microbial, immune system modulator and growth-stimulating properties. In human, CLA is produced from Linoleic acid (LA) by gut bacteria. In this study, nineteen Lactobacillus (Lac.) strains isolated from human feces were studied to determine their ability to metabolize LA. The bacteria were grown in the liquid form of anaerobic MRS medium supplemented with 0.5 mg/mL LA. The linoleate isomerase activi
