Consequences of activity

ANSWER I think that is controversial right now. Yes, I think there is a projection system that runs from the pars reticulata to pars compacta, but the consequences of activation of that system and how you would get access to it are not well understood at this time. 

Considerable efforts have centered on carrying out the synthesis of polybenzimidazoles at more moderate temperatures. Polymerization of the isophthalic acid or its diphenyl ester have been successfully carried out in polyphosphoric acid or methanesulfonic acid-phosphorous pentoxide at 140-180°C, but the reaction is limited by the very low solubilities (<5%) of the reactants in that solvent. The lower reaction temperature is a consequence of activation of the carboxyl reactant via phosphorylation. Lower reaction temperatures are also achieved in hot molten nonsolvents such as sulfolane and diphenyl sulfone, but the need to remove such solvents by a filtration or solvent extraction is a disadvantage.

FIGURE 2—30. One of the consequences of activation of an intracellular enzyme by a second messenger is that some activated enzymes can instruct ion channels to open. This may be mediated by a complicated molecular cascade, set in motion by a second messenger activating an intracellular enzyme, which itself creates still further molecular instructions to an ionic gatekeeper to open the ion channel. 

A3 receptors are present on human eosinophils and couple to signalling pathways that lead to cell activation ( Kohno et al. 1996a Reeves et al. 2000). Despite this it has not proven easy to demonstrate the functional consequences of activation of these sites (Reeves et al. 2000). Nevertheless, the chronic inflammation in asthma is characterised by extensive infiltration of the airways by activated eosinophils (Holgate 1999 Pearlman 1999) and it remains possible that the elevated adenosine concentrations associated with asthma would contribute to eosinophil activation through stimulation of A3 receptors. In addition, it has been speculated that activation of A3 receptors may protect eosinophils from apoptosis (Gao et al. 2001). Thus, blockade of A3 receptors may reduce the numbers of eosinophils and their activation thereby reducing the pro-inflammatory burden in the lung. Consistent with this, following 6 weeks treatment of mild asthmatics with theophylline there was a... 

Transforming growth factor (3 (TGF(3) (that suppresses cell proliferation), the related develop-mentally important activins (involved in mesoderm induction) and bone morphogenetic proteins (involved in bone formation) act via PM-located transmembrane receptors that are Ser/Thr-specific PKs. Thus, TGF(3 binds to the extracellular domain of a specific TGF(3 receptor with the successive consequences of activation of the receptor Ser/Thr-specific PK activity, phosphorylation of a protein Mad to yield P-Mad and downstream consequences resulting in developmentally important specific gene expression. Thus, dorso-ventral differentiation in Xenopus embryos involves Mad-like proteins and a Mad-like gene is a tumour suppressor gene. 

The irreversible inhibition of enzymes by suicide substrates occurs as a consequence of activation steps in which the target enzymes transform these substrates into inhibitors using their normal mechanism.

The normal glomerular filtration rate (GFR) is 100-120 mL/min about 150 L of fluid passes through the renal tubules each day. Since the average daily urine volume is 1 -1.5 L, 99% of the glomerular filtrate is reabsorbed. Approximately 80% of the water is reabsorbed in the proximal tubule, a consequence of active absorption of solutes. Reabsorption in the rest of the tubule varies according to the individual s water balance, in contrast to the obligatory reabsorption that occurs in the proximal tubule. 

Mitogen-activated protein kinase (MAPK) cascades were among the first signaling pathways demonstrated to be activated by ROS. These effects have since been extensively investigated. Here, a brief overview on MAPK properties will be followed by a summary of the known physiological roles of MAPK and a paragraph on the mechanisms and consequences of activation of MAPK cascades by ROS.

Infection with herpes simplex virus type 1 (HSV-1) typically causes diseases of the mouth, face, skin, esophagus, or brain. Herpes simplex virus type 2 (HSV-2) usually causes infections of the genitals, rectum, skin, hands, or meninges. Both cause serious infections in neonates. HSV infection may be a primary one in a naive host, a nonprimary initial one in a host previously infected by other viruses, or the consequence of activation of a latent infection. 

The release of stored neurotransmitters is a consequence of activation of neuronal S-HTg receptors increasing intracellular calcium concentrations. Thus, 5-HT, has long heen known to control the release of acetylcholine (ACh) and noradrenaline (NA) in peripheral tissues. In the central nervous system, the release of NA, ACh, 5-HT, dopamine (DA) and cholecystokinin (CCK) have been shown to be modulated by several 5-HT3 drugs. These biochemical effects, in addition to the presence of 5-HTj sites in expected areas, support behavioural experiments which have estabUshed the putative therapeutic characteristics of 5-HT3 receptor antagonists.
