Measurements of DC susceptibility, AC susceptibility, and AC susceptibility with an applied DC bias field were performed on mechanically milled GdAl2. A paramagnetic phase exists above a temperature T ≈ 140 K. However, there are significant deviations from the Curie-Weiss Law in this temperature regime, suggesting multiple magnetic components. Fits to the high temperature data show that two Cur...

Cryptosporidium parvum is a zoonotic protozoan parasite found worldwide, that develops only in the gastrointestinal epithelium and causes profuse diarrhea. Using a mouse model of C. parvum infection, we demonstrated by conditional depletion of CD11c+ cells that these cells are essential for the control of the infection both in neonates and adults. Neonates are highly susceptible to C. parvum bu...

In 1716 individuals--801 human immunodeficiency virus (HIV)-1-seropositive individuals, 217 high-risk HIV-1-seronegative individuals, and 698 general HIV-1-seronegative individuals--from a Seattle cohort and a Multicenter AIDS Cohort Study cohort, the association between HIV-1 susceptibility and repeat-region polymorphisms in the gene for the dendritic cell-specific intercellular adhesion molec...

Ag presentation by dendritic cells (DC) in vivo is essential to the initiation of primary and secondary T cell responses. We have reported that DC presenting Ag in the context of MHC I molecules also become targets of specific CTL and are rapidly killed in mice. However, activated DC up-regulate expression of serine protease inhibitor (SPI)-6, a specific blocker of the cytotoxic granule protein...

The ubiquitous presence of cell-surface sialic acid (SIA) has complicated efforts to identify specific transmembrane glycoproteins that function as bone fide entry receptors for influenza A virus (IAV) infection. The C-type lectin receptors (CLRs) DC-SIGN (CD209) and L-SIGN (CD209L) enhance IAV infection however it is not known if they act as attachment factors, passing virions to other unknown...

Slow magnetic relaxation is observed for [(tpa(Mes))Fe](-), a trigonal pyramidal complex of high-spin iron(II), providing the first example of a mononuclear transition metal complex that behaves as a single-molecule magnet. Dc magnetic susceptibility and magnetization measurements reveal a strong uniaxial magnetic anisotropy (D = -39.6 cm(-1)) acting on the S = 2 ground state of the molecule. A...

Poly(dG-dC).poly(dG-dC) and poly(dG).poly(dC) were modified by treatment with N-acetoxy-N-2-acetylaminofluorene, and their conformations were examined by circular dichroism and susceptibility to nuclease S1 digestion. A sample of poly(dG-dC).poly(dG-dC) modified to an extent of 28% with acetylaminofluorene (AAF) at the C(8) position of the deoxyguanosine residues showed a circular dichroism spe...
