We studied the possible regulatory effects of 1alpha,25-dihydroxyvitamin D3 [1alpha,25-(OH)2D3] on cytokine production and differentiation of subsets of CD4+ [T helper 1 (Th1) and Th2] and CD8+ [T cytotoxic 1 (Tc1) and Tc2] lymphocytes at the single cell level. PBMC from healthy donors were cultured with or without 1alpha,25-(OH)2D3 for up to 21 days. On days 0, 7, 14, and 21, the percentage of...
BACKGROUND/AIM: Recent studies have suggested a relation of homocysteine with lipid metabolism. The aim of this study was to analyze a possible genetic basis for such a relation in 504 individuals including 135 consecutive Caucasian patients diagnosed with cerebrovascular disease as well as the patients’ healthy spouses (n = 100) and offspring (n = 269). METHODS: We analyzed the association of ...
BACKGROUND Saccharomyces cerevisiae strains expressing D-xylose isomerase (XI) produce some of the highest reported ethanol yields from D-xylose. Unfortunately, most bacterial XIs that have been expressed in S. cerevisiae are either not functional, require additional strain modification, or have low affinity for D-xylose. This study analyzed several XIs from rumen and intestinal microorganisms ...
CD8 T cell-mediated immune responses fall into two distinct types based on effector cell-derived cytokine production. Type I CD8 T cells (Tc1) produce IFN-gamma, whereas type 2 cells (Tc2) secrete IL-4, IL-5, IL-10, and GM-CSF. Using a murine TCR transgenic T cell/breast tumor model, we show that adoptively transferred Ag-specific Tc1 cells are more effective in delaying mammary tumor growth an...
We have carried out a comprehensive multiwavelength study of BrightRimmed Globule TC2 in the Trifid Nebula, using the IRAM 30m telescope, the VLA centimeter array and the Infrared Space Observatory (ISO). TC2 is one of the very few globules to exhibit signs of active ongoing star formation while being photoevaporated by the Ly-c flux of the exciting star of the nebula (∼ 10 cm s). The globule c...
A novel family of miniature inverted repeat transposable elements (MITEs) named Pony was discovered in the yellow fever mosquito, Aedes aegypti. It has all the characteristics of MITEs, including terminal inverted repeats, no coding potential, A+T richness, small size, and the potential to form stable secondary structures. Past mobility of PONY: was indicated by the identification of two Pony i...
OBJECTIVE Pattern analysis has emerged as a tool to depict the role of multiple nutrients/foods in relation to health outcomes. The present study aimed at extracting nutrient patterns with respect to breast cancer (BC) aetiology. DESIGN Nutrient patterns were derived with treelet transform (TT) and related to BC risk. TT was applied to twenty-three log-transformed nutrient densities from diet...
OBJECTIVE Ultraviolet-A1 (UVA1) phototherapy is effective for a variety of dermatological diseases. We examined the effectiveness and reliability of low-dose UVA1 phototherapy (60 kJ/m2/treatment) in patients suffering from systemic lupus erythematosus (SLE). We studied the changes in immunological parameters. METHODS The patients received a 9-week course of phototherapy according to the foll...
OBJECTIVES/HYPOTHESIS Immunoglobulin G4 (IgG4)-related sclerosing sialadenitis is a recently recognized disease entity characterized by high serum IgG4 concentration and IgG4-producing plasma cell expansion in affected organs, which show fibrotic or sclerotic changes. However, little is known about the roles of CD4+ and CD8+ T cells or interleukin (IL)-17 in this disease. The purpose of this st...
The compounds Tc2Cl4(PMe3)4 and Tc2Br4(PMe3)4 were formed from the reaction between (n-Bu4N)2Tc2X8 (X = Cl, Br) and trimethylphosphine. The Tc(II) dinuclear species were characterized by single-crystal XRD, UV-visible spectroscopy, and cyclic voltammetry techniques, and the results are compared to those obtained from density functional theory and multiconfigurational (CASSCF/CASPT2) quantum che...
