Dendritic cells can take up exogenous tumor antigens and present their antigenic epitopes to CD8⁺ T cells (T(CD8⁺)), a process called cross-presentation. Cross-presentation is especially important in antitumor immunity because tumor cells, although carrying tumor antigens, do not activate naive T cells efficiently because of a lack of co-stimulatory molecules. Our group has recently shown that ...

We demonstrate a novel cross-sectional deformation, called the radial corrugation, of multi-walled carbon nanotubes (MWNTs) under hydrostatic pressure. Theoretical analyses based on the continuum elastic approximation have revealed that MWNTs consisting of more than ten concentric walls undergo elastic deformations at critical pressure pc ≃ 1 GPa, above which the circular shape of the cross sec...

there are increasing reports of emergence of multiple drug resistant (mdr) acinetobacter spp in the world; however there are a few reports in our country. 145 a. baumannii isolates from distinct wards and children's medical center (cmc) in tehran were studied in order to find the profile of antibiotic resistance among them. 40.6% (59/145) of a. baumannii isolates were identified as mdr. overall...

in this study, the relative performance of mazandaran wood and paper company as a major supplier of paper products in iran was measured. network data envelopment analysis (dea) models with parallel structure were used to evaluate and measure its performance. gams software version 23.4 was used for data analysis. results indicated that this company in all studied years had good performances base...

background: allergens are mostly composed of glycoprotein structures. it is believed that glycan-specific antibodies may lead to false-positive reactions in immunoassays. in this study we investigated the glycosylation state of grape allergens as well as the presence of antibodies to cross-reactive carbohydrate determinants (anti-ccds) in sera from grape-sensitive individuals. methods: grape ex...

We develop a technique to measure radial velocities of stars from spectra that present four sets of lines. The algorithm is an extension of the two-dimensional cross-correlation method TODCOR to four dimensions. It computes the correlation of the observed spectrum against a combination of four templates with all possible shifts, and allows also for the derivation of the light ratios of the comp...

in a supply chain, cross-docking is one of the most innovative systems for ameliorating the operational performance at distribution centers. cross-docking is a logistics strategy in which freight is unloaded from inbound trucks and (almost) directly loaded into outbound trucks, with little or no storage in between, thus no inventory remains at the distribution center. in this paper, we consider...

in this paper, we intend to investigate the impact of privatization on economic growth in developing and transition economies. previous studies that have attempted to measure this relationship have conflicting results, some indicating a positive impact of privatization on growth, while others indicate a negative relationship. our study uses recent world bank data on privatization for 117 countr...

background : muscle cramps are painful manifestations that occur in many cirrhotic patients. this study aims to evaluate the risk factors for developing muscle cramps. materials and methods: this cross-sectional study evaluated 24 cirrhotic patients (18 male, 6 female) during 15 months. patients underwent careful examinations administered by the same person to determine the underlying cause of ...
