BACKGROUND & OBJECTIVES Variability in the clinical outcome of persons exposed to and infected with HIV-1 and tuberculosis (TB) is determined by multiple factors including host genetic variations. The aim of the present study was to find out whether chemokine, chemokine receptor and DC-SIGN gene polymorphisms were associated with susceptibility or resistance to HIV and HIV-TB in south India. ...

A novel two-dimensional coordination polymer of the formula [Co(dca)2(atz)2]n () resulted from assembling trans-bis(2-amino-1,3,5-triazine)cobalt(ii) motifs by dicyanamide spacers. Variable-temperature dc and ac magnetic susceptibility measurements of show that the high-spin cobalt(ii) ions act as single ion magnets (SIMs).

The dining cryptographers network (or DC-net) is a seminal technique devised by Chaum to solve the dining cryptographers problem — namely, how to send a boolean-OR bit anonymously from a group of participants. In this paper, we investigate the weaknesses of DC-nets, study alternative methods and propose a new way to tackle this problem. Our protocol, Anonymous Veto Network (or AV-net), overcome...

The nucleotide oligomerization domain 2 (NOD2) 3020insC (NOD2fs) mutation increases susceptibility to Crohn's disease (CD), but the mechanism remains controversial. Loss-of-function and gain-of-function phenotypes have been described as a result of NOD2fs. Here, we show that dendritic cells (DC) derived from CD patients homozygous for this mutation respond normally to purified Toll-like recepto...

γδ T cells function at the interface between innate and adaptive immunity and have well-demonstrated roles in response to infection, autoimmunity and tumors. A common characteristic of these seemingly disparate conditions may be cellular stress or death. However, the conditions under which ligands for γδ T cells are induced or exposed remain largely undefined. We observed that induction of necr...

Measles caused by measles virus (MV) infection remains important in child mortality. Although the natural host of MV is human, mouse models expressing MV entry receptors (human CD46, CD150) and disrupting the interferon (IFN) pathways work for investigating immune responses during early MV infection in vivo. Dendritic cells (DCs) are primary targets for MV in the mouse models and are efficientl...

Pinning properties in 100nm thick continuous and porous superconducting Nb films are examined by ac susceptibility and dc magnetization measurements. The Nb filmwas deposited on a smooth Si substrate, while the porous film, NbP , was deposited on an anodized Al oxide substrate. Pores or ‘‘antidots’’ 40 nm in diameter, 100 nm apart, form a triangular array. The porous film presents commensurate ...

Dielectric relaxation and thermal expansion spectroscopy were made for thin polystyrene films in order to measure the temperature Tα corresponding to the peak in the loss component of susceptibility due to the α-process and the α-relaxation time τ as functions of film thickness d. While the glass transition temperature Tg decreases with decreasing film thickness, Tα and τ were found to remain a...

The magnetization dynamics of magnetic nanoparticles are essential for the medical applications hyperthermia and particle imaging. In this paper, we clarified AC susceptibility superparamagnetic their frequency dependence. We measured under an applied DC bias field. dependence was clearly observed. experimentally obtained characteristics samples with different effective core diameters on intens...
