Regulation functional

The modern DDC controller has only the control function PID. PLC controllers used in process installations may contain more complex regulation functions, for example, the fuzzy or auto-tuning of PID functions. Most DDC controllers are self-sufficient and independent of the controllers or computer programs that are used for system configuration. 

Sex steroid receptors are members of the steroid hormone receptor (SHR) family that ligand-dependently regulate functions of the sexual organs. Sex steroid receptors are the androgen receptor [1] (AR), the estrogen receptor a [2] and (3 [3] (ERa, ER 3), and the progesterone receptor [4] (PR). 

The glucocorticoids influence or regulate functions such as the immune response system, the regulation of glucose, fat and protein metabolism, and control of the anti-inflammatory response. Table 50-1 describes the activity of the glucocorticoids within the body. 

Thus far, microtubules and actin filaments and their associated proteins have been discussed to advantage as independent cytoskeletal components. In actual fact, all of the components of the cytoskeleton (including intermediate filaments) are precisely integrated with one another (Langford, 1995), as well as with various cytoplasmic organelles, the nuclear membrane, the plasma membrane, and the extracellular matrix. In its totality the cytoskeleton subserves many coordinated and regulated functions in the cell ...

Claude Bernard s early discovery (1856) that curare, the South American arrow poison (woorari), blocked muscle contraction elicited by stimulation of motor neurons, but not that elicited by direct stimulation of the muscle, provided the first demonstration that drugs could be used to study, what we now know are, nAChR-regulated functions. Bernard s early experiment served as the model for Langley s demonstration that the actions of nicotine on skeletal muscle could be blocked by pretreatment with curare (Langley 1880, 1907) and mimicked by pituri, the active... 

Inhaled nicotine is efficiently delivered to the brain (see chapter by Benowitz, this volume) where it selectively interacts with its central targets, the neuronal nicotinic acetylcholine receptors (nAChRs). The multiple subtypes of uAChR (see chapter by Collins et al, this volume) all bind nicotine but with different affinities, depending on the subunit composition of the uAChR. Binding may result in activation or desensitisation of uAChRs, reflecting the temporal characteristics of nicotine dehvery and local concentration of nicotine. Another level of complexity of the actions of nicotine reflects the widespread and non-uniform distribution of uAChR subtypes within the brain, such that nicotine can influence many centrally regulated functions in addition to the reward systems. In this chapter, we address the consequences of nicotine interactions with nAChRs at the molecular, cellular and anatomical levels. We critically evaluate experimental approaches, with respect to their relevance to human smoking, and contrast the acute and chronic effects of nicotine. 

The inhibitor pl6 4 is attributed properties as a tumor suppressor since the gene for pl6 4a jg mutated in many tumor cell lines. There is evidence that the pRb protein (see 13.3.2) performs a regulating function on transcription of pl6 . 

Another gene controlled by p53 is the gene for the Bax protein (Miyashita and Reed, 1995). The Bax protein has an activating function in the initiation of apoptosis. Activation of the p53 protein due to DNA damage can initiate the apoptotic program via stimulation of bax transcription (see Chapter 15). If the transcription regulating function of p53 is lost due to an oncogenic mutation, this apoptotic path caimot be initiated.
