This monographic issue of Current Pharmacological Design discusses extensively on the innovative paradigms for disease control in Active and Healthy Ageing. Wellness, as a status to be achieved and maintained in our lives, getting longer and hopefully healtier, is the new and comprehensive declination of “health” itself, leading the shaping of research and research policy in the health domain worldwide. Many of the contributions describe the state of the art –and beyond- approaches for the most common diseases based on the available medical knowledge; two, in particular (Bousquet J et al., Cesario A, et al.), extend to the innovative approaches defined in the framework of the holistic and integrative philosophy of the Predictive, Preventive, Personalized and Participatory (P4) Systems Medicine. The availability of more and more powerful technologies to extract data coupled with the inclusion of information coming from the nonstrictly- medical sphere of the patient/individual and his/her lifestyle along with the increase in computational power, will definitely set the stage for a paradigm-shift in bio-medicine with deep ethical and societal impact. The brief comment that follows speculates about the implications of this transition from the educational perspective taking stock of the direct experience of the Authors in the consultation process active in the scientific community. © 2014 Bentham Science Publishers.

The two essential requirements for pathologic specimens in the era of personalized therapies for non-small cell lung carcinoma (NSCLC) are accurate subtyping as adenocarcinoma (ADC) versus squamous cell carcinoma (SqCC) and suitability for EGFR molecular testing, as well as for testing of other oncogenes such as EML4-ALK and KRAS. Actually, the value of EGFR expressed in patients with NSCLC in predicting a benefit in terms of survival from treatment with an epidermal growth factor receptor targeted therapy is still in debate, while there is a convincing evidence on the predictive role of the EGFR mutational status with regard to the response to tyrosine kinase inhibitors (TKIs). This is a literature overview on the state-of-the-art of EGFR oncogenic mutation in NSCLC. It is designed to highlight the preclinical rationale driving the molecular footprint assessment, the progressive development of a specific pharmacological treatment and the best method to identify those NSCLC who would most likely benefit from treatment with EGFR-targeted therapy. This is supported by the belief that a rationale for the prioritization of specific regimens based on patient- tailored therapy could be closer than commonly expected. Source

In the years from 1856 to 1936, when the Nobel Prize for Physiology/Medicine was awarded to Dale and Loewi for their discoveries relating to chemical transmission of nerve impulses, the nicotinic acetylcholine receptor (nAChR) emerged from an assumption to a reality. Its biochemical isolation in 1970 represents a major breakthrough in pharmacology. The α7-nAChR subunit forms homo-oligodimeric nAChR with unique distinctive properties, such as high permeability to calcium and modulation by the extracellular calcium concentrations, the possibility of binding two-five molecules of agonist, function modulation via phosphorylation and/or via calcium-dependent serine/threonine kinases and modulating transmitter release and activation of GABAergic interneurons. In the brain, the α7-nAChR plays several important functions running from synaptic plasticity, regulation of neuronal growth, differentiation and survival to enhance learning and cognition. The detection of its occurrence on non-neuronal cells raises question related to their specific activity, since in these cells it appears involved in modulation of cell death, migration and signaling. Its unbalance might involve it in different diseases such as Alzheimer, Parkinson and cancer. However, the peculiarity of α7-nAChR offers rational bases to develop new drugs and new therapeutic strategies. In conclusion, α7-nAChR roughly in 150 years of life, instead to be an old actor became an important player in regulating cell signaling. © 2012 Bentham Science Publishers. Source

The presence of memory impairment and cognitive deficits in the Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Pick's disease (PiD) has been associated to dysfunction of cholinergic transmission, possibly due to the loss of cholinergic neurons and to the elimination of nAChR in dementia patients. Alternative hypotheses take into account molecular interactions of the β-amyloid peptide A β with nAChR, which may lead to deregulation of the receptor function. Genetic polymorphisms of CHRNA7 and CHRFAM7A, a fusion gene containing a partial CHRNA7 duplication, have been investigated as possible susceptibility traits to dementia, potentially useful either to identify high risk individuals or as therapeutic targets. To summarize the existing evidence, a systematic re-evaluation of published papers has been performed (PubMed database, no language restriction, updated to 1 st August 2011). Eleven articles reporting data on genetic variations in CHRNA7 or CHRFAM7 and risk of dementia fulfilled selection criteria and were evaluated. Published evidence on the association between variations in CHRNA7 or CHRFAM7A and the risk of dementia is still sparse and inconclusive. Further studies are needed to establish whether some polymorphisms may really affect the probability of developing AD or other forms of dementia. Additional and more conclusive results may come from the ongoing GWAS studies investigating high numbers of genetic variants in large samples, that have the potential to assess the role of genetic susceptibility in dementia. © 2012 Bentham Science Publishers.

Long-acting muscarinic receptor antagonists (LAMAs) and long-acting β2-adrenoceptor agonists (LABAs) cause airway smooth muscle (ASM) relaxation via different signal transduction pathways, but there are limited data concerning the interaction between these two drug classes on human bronchi. The aim of this study was to investigate the potential synergistic interaction between aclidinium bromide and formoterol fumarate on the relaxation of human ASM. We evaluated the influence of aclidinium bromide and formoterol fumarate on the contractile response induced by acetylcholine or electrical field stimulation (EFS) on human isolated airways (segmental bronchi and bronchioles). We analyzed the potential synergistic interaction between the compounds when administered in combination by using Bliss independence (BI) theory. Both aclidinium bromide and formoterol fumarate completely relaxed segmental bronchi pre-contracted with acetylcholine (Emax: 97.5±2.6% and 96.4±1.1%; pEC50 8.5±0.1 and 8.8±0.1; respectively). Formoterol fumarate, but not aclidinium bromide, abolished the contraction induced by acetylcholine in bronchioles (Emax: 68.1±4.5% and 99.0±5.6%; pEC50 7.9±0.3 and 8.4±0.3; respectively). The BI analysis indicated synergistic interaction at low concentrations in segmental bronchi (+18.4±2.7%; P<0.05 versus expected effect) and from low to high concentrations in bronchioles (+19.7±0.9%; P<0.05 versus expected effect). Low concentrations of both drugs produced a synergistic relaxant interaction on isolated bronchi stimulated with EFS that was sustained for 6 h post-treatment (+55.1±9.4%; P<0.05 versus expected effect). These results suggest that combining aclidinium bromide plus formoterol fumarate provides synergistic benefit on ASM relaxation of both medium and small human airways, which may have major implications for the use of this combination in the clinic. © 2014 The Authors.
