capture elisa system was developed for diagnosis of visceral leishmaniasis (vl) using a monoclonal antibody raised against an antigen previously detected in the urine of vl patients. urine samples from confirmed vl cases from yemen, nepal, spain, sudan and brazil were tested in the capture elisa in comparison with urine samples from endemic and non-endemic areas along with urine samples from pa...

The chromatin structure of a diploid precursor B-cell line (REH), in >>/fro-stimulated normal B-lymphocytes, and reactive and malignant lymph node B-lymphocytes was studied by staining formaldehyde-fixed, permeabilized cells with the DNA-specific ftuorophore 7-aminoactinomycin D (7-AMD) and measuring single-cell fluorescence by flow cytometry. Resting peripheral blood Band T-lymphocytes (Go cel...

leptospirosis is one of the most prevalent zoonotic diseases worldwide. currently, multivalent whole-cell leptospiral vaccines can induce protection against leptospirosis. therefore, preparation and formulation of new generations of vaccines that can stimulate long-term immunity for leptospirosis control are essential. the aim of this study was to prepare and characterize alginate microspheres ...

the liver fluke fasciola hepatica causes fascioliasis, a liver disease in most part of the world and particularly in north of iran. diagnosis of the diseases is anchored in coprological manner but serological methods are preferable due to some obscurities. in this study, sera obtained from human patients infected with fasciola hepatica were tested by the enzymelinked immunotrotransfer blot (eit...

The currently identified cDNA clones of mammalian amino acid transporters can be grouped into five different families. One family is composed of the proteins rBAT and the heavy chain (hc) of the cell surface antigen 4F2. RNAs encoding these two proteins induce a system b(o,+)-like (rBAT) and a system y+L-like (4F2hc) activity in Xenopus oocytes. Surprisingly, rBAT and 4F2hc do not seem to be po...

The chromatin structure of a diploid precursor B-cell line (REH), in vitro-stimulated normal B-lymphocytes, and reactive and malignant lymph node B-lymphocytes was studied by staining formaldehyde-fixed, permeabilized cells with the DNA-specific fluorophore 7-aminoactinomycin D (7-AMD) and measuring single-cell fluorescence by flow cytometry. Resting peripheral blood B- and T-lymphocytes (G0 ce...

GP-SIMD, a novel hybrid general purpose SIMD architecture, addresses the challenge of data synchronization by in-memory computing, through combining data storage and massive parallel processing. In this paper, we explore a resistive implementation of the GP-SIMD architecture. In resistive GP-SIMD, a novel resistive row and column addressable 4F2 crossbar is utilized, replacing the modified CMOS...

Introduction. Let C be a finite polyhedral complex, i.e., a finite nonempty collection of convex polytopes in R such that (i) when P,Q E C then P flQ is a face of both and (ii) if P E C and Q is a face of P then Q EC. Let fi = fa(C) be the number of i-dimensional members of C, i > 0, called the iih face number. The discovery that the numbers fi are governed by interesting relations is due to Eu...
