Although immunoregulation of alloreactive human CTLs has been described, the direct influence of CD4(+) Tregs on CD8(+) cytotoxicity and the interactive mechanisms have not been well clarified. Therefore, human CD4(+)CD127(-)CD25(+)FOXP3(+) Tregs were generated in MLR, immunoselected and their allospecific regulatory functions and associated mechanisms were then tested using modified (51)Chromi...

In the present study, there was a complete lack of autologous MLR between responding T cells or T subsets and unirradiated or irradiated leukemic B cells or monocytes in all 20 patients with CLL, regardless of disease status, stage, phenotype, or karyotype of the disease. The stimulating capacity of unirradiated CLL B cells and CLL monocytes or irradiated CLL B cells was significantly depressed...

Quantitative Structure-Property Relationship (QSPR) models for modeling and predicting thermodynamic properties such as the enthalpy of vaporization at standard condition (ΔH˚vap kJ mol-1) and normal temperature of boiling points (T˚bp K) of 57 mono and Polycyclic Aromatic Hydrocarbons (PAHs) have been investigated. The PAHs were randomly separated into 2 groups: training and test sets. A set o...

a quantitative structure-activity relationship (qsar) study was conducted for the prediction of inhibitory activity of 1-phenyl[2h]-tetrahydro-triazine-3-one analogues as inhibitors of 5-lipoxygenase. the inhibitory activities of the 1-phenyl[2h]-tetrahydro-triazine-3-one analogues modeled as a function of molecular structures using chemometrics methods such as multiple linear regression (mlr) ...

Many multilevel relational data models have been proposed, and diierent models ooer diierent advantages. In this paper, we adapt and reene several of the best ideas from previous models and add new ideas to build the new Multilevel Relational (MLR) data model. MLR provides multilevel relations with element-level labeling, as a natural extension of the traditional relational data model. MLR intr...

CD83 is a marker of dendritic cell (DC) differentiation/activation and its expression in the mouse thymus contributes to CD4(+) T lymphocyte development. Its extrathymic role remains unclear despite the functional effects observed with CD83 fusion proteins or CD83 antibody and recent reports of potential ligands. We investigated the previously observed and presumed functional blockade of the al...

Locomotor modulation of disynaptic EPSPs from the mesencephalic locomotor region in cat motoneurons. J. Neurophysiol. 80: 3284-3296, 1998. When low-frequency tetanization of the mesencephalic locomotor region (MLR) produce fictive locomotion in unanesthetized, decerebrate cats, each MLR stimulus produces a distinctive cord dorsum potential (CDP) and oligosynaptic excitatory postsynaptic potenti...

The auditory middle latency response (MLR), a useful tool in the assessment of low-frequency auditory sensitivity, can be consistently recorded in young children during wakefulness, stages 1 and 2, and REM sleep. Responses are often absent or questionable during stage 4. An on-line measure indicating favorable periods for recording MLR during sleep is important for interpretation of absent pote...
