Efficient stimulator

One of the important relay stations in the immune system activation is the dendritic cell. Activation of these cells causes the most efficient stimulation of T-cells, which in turn attack tumor cells (9). This turned the dendritic cells (DCs) into the focus of modern immune research and therapy. However, another difficulty appeared that became a problem recently. In order to activate the dendritic cell, the antigen has to be present in the cytosol and has to be processed there further this is not an easy task to perform. [Pg.208]

The primary signaling pathway of 5-HT4 receptors is the stimulation of AC in tissues (297,298,315-318) or when heterologously expressed in cells (299-302,307,308,311,312,319), and all of the splice variants appear to efficiently stimulate AC. [Pg.172]

When the efficacy of biphalin-stimulated G protein activation was examined (Table 3) in delta opioid receptor-transfected CHO cells, an efficacy ratio of 0.42 was determined as compared with deltorphin-II and DPDPE, the latter a reference delta-selective agonist. Such low efficacy values suggest that biphalin does not efficiently stimulate the G protein through the delta receptor [9]. Relative affinities of biphalin and morphine for mu, delta, and kappa binding sites in guinea pig brain membranes are shown in Table 4. [Pg.248]

There are two important experimental factors that must be accounted for if we are to be successful in running 15N experiments. The 15N nucleus tends to relax very slowly Tj s of greater than 80 seconds have been measured. Thus, either long pulse delays must be incorporated into our pulse sequence or, alternatively, we could provide another route for spin relaxation. A common procedure is to add a catalytic amount of chromium (III) acetylacetonate, a paramagnetic substance, whose unpaired electrons efficiently stimulate transfer of spin. In cases where Tt s are not known (and not intended to be measured), pulse delays and pulse angles must be considered carefully because the signal from one (or more) 15N resonance can accrue too slowly or be missed altogether. [Pg.317]

Taken together, these results suggest that several receptors are efficiently stimulated only by membrane-bound or cross-linked ligands. This probably provides a threshold ensuring that the signal is only transmitted under defined conditions, such as a cell-to-cell contact. [Pg.215]

Adjuvants such as QS21 or CpG-ODN have been described which induce a type 1 cellular immune response, whereas in contrast, aluminum hydroxide was shown to induce a type 2 immune response. Thus, it is important to choose the correct adjuvant(s) that is required to initiate a humoral and/or cellular as well as type 1 and/or type 2 immune response by vaccination. For an efficient stimulation of an immune response capable of eliminating a... [Pg.1424]

Recent gains using foamed fluids result from the improvements in on-site quality control. More accurate monitoring equipment, the ability to adjust input parameters during the treatment, and real-time calculations of bottomhole pressures and qualities enable more accurate rheology calculations, and thus allow for high-efficiency stimulations and improved productivity gains. [Pg.398]

X.S. Teefore has increased thyroid hormone levels that increase his rate of ATP utilization and fuel oxidation. An excess of thyroid hormones also may affect the efficiency of ATP production, resulting in fewer ATP produced for a given O2 consumption. The increased rate of ATP utilization and diminished efficiency stimulates oxidative metabolism, resulting in a much greater rate of heat production. The hyperthyroid patient, therefore, complains of constantly feeling hot (heat intolerance) and sweaty. (Perspiration allows dissipation of excess heat through evaporation from the skin surface.)... [Pg.351]

In the three-body reaction (Reaction [13.5]), the Ne acts as a buffer. Given that the krypton fluoride so produced is electronically excited and has a short lifetime (about 2.5 ns), it rapidly decays by photon emission to the lower energy state as shown in Fig. 13.5. Because this is an unbound state in which the force between the atoms is always repulsive, the exciplex molecule then immediately dissociates into its constituent atoms. As a result, this state never attains a large population, and a population inversion therefore exists between it and the higher energy bound exciplex state. The decay transition can therefore be efficiently stimulated to produce laser emission. One noteworthy characteristic of this particular laser system is that it represents a rare example of a truly two-level laser. [Pg.612]

Only a small fraction of the atmospheric flux of iron to the oceans ever becomes bioavailable, largely because of the low solubihty of the particulate and colloidal Fe(lll) phases that comprise the bulk of aerosol iron species. Nonetheless, bottle incubation experiments have shown that aerosol addition is an efficient stimulator of chlorophyll and biomass production in phytoplankton cultures [105,106], emphasizing the need to understand the factors and processes controlling the chemical speciation and solubihty of aerosol iron before and after deposition. [Pg.162]

Finding the molecular structure for the efficient stimulator and inhibitor is carried out in the following way ... [Pg.78]

Very useful information is provided by the calculated kinetic trajectories of the value contributions of individual steps, for the cases when a stimulator or inhibitor with optimum molecular structure participates in a reaction. Ranking the steps by the contribution of reactions with participation of stimulators, inhibitors and their intermediates, enables to answer the question what reaction or reactions namely play the dominant role, and finally to determine the structure of the most efficient stimulator or inhibitor. [Pg.79]

The above described procedure on finding the structure for the efficient stimulators and inhibitors obviously is based on the kinetie model. Here, the specification of equations (4.33) is also implied, which expresses the dependence of the rate constants of steps (involving the initial speeies of the reaction system and its intermediates) on the reactivity indices of the initial stimulators and inhibitors. However, in many cases just designing such kinetic models requires the serious creative efforts of researehers. [Pg.80]

It should be emphasized that numerical calculations that enable the predicting of steps and species of the reaction, with which the latter may be efficiently controlled, represent a new and promising trend in chemical investigations. As mentioned above, one of the consequences of such an approach is the opportunity to define the molecular structure of the complex reaction s efficient stimulators and inhibitors. [Pg.190]

In this book we also addressed such an important issue of theoretical chemistry as the reactivity of species of multistep chemical reactions. A procedure was offered to identify the molecular structure of efficient reaction stimulators (the catalyst, initiator, promoter) and inhibitors. For this pmpose the rate constants of individual steps involving the initial forms and their intermediate products were expressed through reaction indices, characterizing the initial molecule of a stimulator or inhibitor. Considering the reactivity indices as parameters for controlling the chemical reaction system we succeeded in the identification of molecular design for the most efficient stimulator or inhibitor of a complex reaction. [Pg.209]
