Six solid phases of [Mn(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry. The phase transitions were found between the following solid phases: stable KIc ↔ stable KIb at TC5 = 225 K, metastable KIII ↔ metastable KII at TC4 = 322 K, stable KIb → stable KIa at TC3 = 365 K, metastable KII ↔ overcooled K0 at TC2 = 376 K and stable KIa → stable K0 at TC1 = 379 K. The title comp...

Let S be a random nonnegative definite matrix and let G be an orthogonal matrix such that S = GDG', where D is the diagonal matrix of the latent roots of S. In this note, we prove _ r G t t Gt21 the a.s. existence of G~I, where G-tc2~ c=j, under some weak conditions on the distribution of S. AMS Subject Classification: Primary 62H10, 60D05.

Ramsey’s test for conditionals seems to be in conflict with the so-called Thomason conditionals. A Thomason conditional is a conditional in which either the antecedent or the consequent is a statement about the reasoning agent’s own beliefs. Several authors have pointed out that resolving the apparent conflict is to be sought by abandoning the belief revision interpretation of the Ramsey test i...

Cross-talk between TGF-beta and IL-6 has been shown to direct the differentiation of CD4(+) cells into special IL-17-secreting cells, which are termed Th17 cells. In this study, we demonstrated that TGF-beta and IL-6 could stimulate CD8(+) cells to differentiate into noncytotoxic, IL-17-producing cells in MLC. These IL-17-producing CD8(+) cells exhibit a unique granzyme B(-)IFN-gamma(-)IL-10(-)...

OBJECTIVE Few inflammatory markers closely reflect the activity of tuberculosis and only a few surrogate markers are available. The purpose of this study was to clarify the usefulness of measuring the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum amyloid A (SAA), and the association between these markers and T-cell profiles. METHODS One hundred one patients with ac...

Cytotoxic T lymphocytes (Tc) play a central role in cellular immunity against cancers. The cytotoxic potential of freshly isolated tumor-infiltrating lymphocytes (TILs) is usually not expressed. This suggests the possible existence of as yet unspecified and perhaps complex immunosuppressive factors or cytokines that affect the anti-tumor capacity of these TILs in the tumor milieu. In the presen...

Adoptive T-cell therapy using CD3/CD28 co-stimulation likely requires in vivo generation of antigen specificity. Because CD28 promotes TH1/TC1 (T1) or TH2/TC2 (T2) differentiation, costimulation may generate donor T1 or T2 cells capable of differentially mediating allogeneic graft-versus-tumor (GVT) effects and graft-versus-host disease (GVHD). Costimulation under T1 or T2 conditions indeed gen...
