The present studies were designed to investigate the mechanism(s) of the defective T cell proliferative response to various stimuli in patients with B cell chronic lymphocytic leukemia B-CLL. In 14 patients with advanced B-CLL (stage III or IV) we found the T cell response in the autologous (auto) and allogeneic (allo) mixed lymphocyte reaction (MLR) to be 35.7% and 30% of the controls, respect...

A biologically based neuromuscular simulator was used to produce short(SLR) and medium-latency reflexes (MLR) observed after a stretch of the SO muscle. As expected, SLR was exclusively mediated by the activity of Ia afferents passing through a monosynaptic pathway. The MLR was generated by a summation of effects from Ia and type-II afferents, though it could be generated without the activity o...

A quantitative structure-property relationship (QSPR) study is suggested for the prediction of retention times of volatile organic compounds. Various kinds of molecular descriptors were calculated to represent the molecular structure of compounds. Modeling of retention times of these compounds as a function of the theoretically derived descriptors was established by multiple linear regression (...

The main aim of the present work was development of a quantitative structure-property relationship method using an artificial neural network (ANN) for predicting gas-to-olive oil partition coefficients of organic compounds. As a first step, a multiple linear regression (MLR) model was developed; the descriptors appearing in this model were considered as inputs for the ANN. These descriptors are...

Pain is a highly subjective experience, and the availability of an objective assessment of pain perception would be of great importance for both basic and clinical applications. The objective of the present study is to develop a novel approach to extract pain-related features from single-trial laser-evoked potentials (LEPs) for classification of pain perception. The single-trial LEP feature ext...

Multiple linear regression (MLR) is a popular method for producing forecasts when data on relevant independent variables (or cues) is available. The accuracy of the technique in forecasting the impact on Greek TV audience shares of programmes showing sport events is compared with forecasts produced by: (1) a simple bivariate regression model, (2) three different types of artificial neural netwo...

Models for the prediction of conductance in nonbrine water samples through the measurement of ionic concentrations and other parameters are compared. Such predictions are often used for quality assurance purposes by comparing them with actual measurements to determine whether gross analysis errors have been made. A currently recommended method for making such predictions is a semiempirical rela...

Profile-Based Location Caching with Fixed Local Anchor (PCFLA) Strategy can reduce the frequent access to the HLR. As a result, the total management cost is minimized in a wireless mobile network. However, if the MT’s information is not found at calling MSC then the HLR is accessed to get that information every time. Middle Location Register (MLR) is located between VLR and HLR. It helps to red...

Although mesencephalic locomotor region (MLR) stimulation and the exercise pressor reflex have been shown to increase whole nerve renal sympathetic activity, it is not known whether these mechanisms converge onto the same population of renal sympathetic postganglionic efferents. In decerebrate cats, we examined the responses of single renal sympathetic postganglionic efferents to stimulation of...

Addition of polydispersed acid functionalised single-walled carbon nanotubes (AF-SWCNTs) significantly suppressed alloimmune cytotoxic T cell (CTL) response generated in a mixed lymphocyte reaction (MLR) between spleen cells from C57BL/6 (H-2(b)) and BALB/c (H-2(d)) mice. AF-SWCNTs treatment also decreased CD69 expression, enhanced apoptotic response in T cells and reduced significantly the rec...
