Chronic helminth infections are known to be associated with modulation of Ag-specific CD4(+) T responses. However, the role of CD4(+) T cell responses in human infection with Strongyloides stercoralis is not well defined. To examine the role of CD4(+) T cells expressing Th1, Th2, and Th17 cytokines in strongyloidiasis, we compared the frequency (Fo) of these subsets in infected (INF) individual...
We propose dual thermodynamics corresponding to black hole mechanics with the identifications E → A/4, S → M , and T ′ → T−1 in Planck units. Here A, M and T are the horizon area, mass and Hawking temperature of a black hole and E, S and T ′ are the energy, entropy and temperature of a corresponding dual quantum system. We show that, for a Schwarzschild black hole, the dual variables formally s...
HCV infection has a severe course of disease in HIV/HCV co-infection and in liver transplant recipients. However, the mechanisms involved remain unclear. Here, we evaluated functional profiles of HCV-specific T-cell responses in 86 HCV mono-infected patients, 48 HIV/HCV co-infected patients and 42 liver transplant recipients. IFN-gamma and IL-2 production and ability of CD4 and CD8 T cells to p...
The purpose of the present paper is to show that: Eilenberg–type correspondences = Birkhoff’s theorem for (finite) algebras + duality. We consider algebras for a monad T on a category D and we study (pseudo)varieties of T– algebras. Pseudovarieties of algebras are also known in the literature as varieties of finitealgebras. Two well–known theorems that characterize varieties and pseudovarie...
Single and dual amino acid substitution variants were generated in the TCR CDRs of three TCRs that recognize tumor-associated Ags. Substitutions that enhance the reactivity of TCR gene-modified T cells to the cognate Ag complex were identified using a rapid RNA-based transfection system. The screening of a panel of variants of the 1G4 TCR, that recognizes a peptide corresponding to amino acid r...
For a simple bipartite graph and an integer t ≥ 2, we consider the problem of finding a minimum-weight t-factor under the restriction that it contains no complete bipartite graph Kt,t as a subgraph. When t = 2, this problem amounts to the minimum-weight square-free 2-factor problem in a bipartite graph, which is NP-hard. We propose, however, a strongly polynomial algorithm for a certain case wh...
Leukemic cells from 20 patients with chronic lymphocytic leukemia (CLL) and 60 patients with acute lymphocytic leukemia (ALL) were studied for T- and B-lymphocyte cell surface membrane markers. B-cell markers included surface membrane immunoglobulin, erythrocyte-antibody complement rosette formation, and B-cell (a-like or HLA-DR) antigens detected by a B-cell antiserum. T-cell markers included ...
Because of insufficient migration and antitumor function of transferred T cells, especially inside the immunosuppressive tumor microenvironment (TME), the efficacy of adoptive cell transfer (ACT) is much curtailed in treating solid tumors. To overcome these challenges, we sought to reenergize ACT (ReACT) with a pathogen-based cancer vaccine. To bridge ACT with a pathogen, we genetically enginee...

Our main deterministic result Theorem 1 is proved by duality. We first establish a set of conditions on the optimal dual variable of D 0 corresponding to all primal solutions satisfying self-expression property. Then we construct such a dual variable ν, hence certify that the optimal solution of P 0 satisfies the LASSO Subspace Detection Property. Define general convex optimization: min c,e c 1...
