Neurodegenerative diseases (NDDs), including Alzheimer's disease (AD) and Parkinson's disease (PD), affect the ageing population worldwide and while severely impairing the quality of life of millions, they also cause a massive economic burden to countries with progressively ageing populations. Parallel with the search for biomarkers for early detection and prediction, the pursuit for therapeutic approaches has become growingly intensive in recent years. Various prospective therapeutic approaches have been explored with an emphasis on early prevention and protection, including, but not limited to, gene therapy, stem cell therapy, immunotherapy and radiotherapy. Many pharmacological interventions have proved to be promising novel avenues, but successful applications are often hampered by the poor delivery of the therapeutics across the blood-brain-barrier (BBB). To overcome this challenge, nanoparticle (NP)-mediated drug delivery has been considered as a promising option, as NP-based drug delivery systems can be functionalized to target specific cell surface receptors and to achieve controlled and long-term release of therapeutics to the target tissue. The usefulness of NPs for loading and delivering of drugs has been extensively studied in the context of NDDs, and their biological efficacy has been demonstrated in numerous preclinical animal models. Efforts have also been made towards the development of NPs which can be used for targeting the BBB and various cell types in the brain. The main focus of this review is to briefly discuss the advantages of functionalized NPs as promising theranostic agents for the diagnosis and therapy of NDDs. We also summarize the results of diverse studies that specifically investigated the usage of different NPs for the treatment of NDDs, with a specific emphasis on AD and PD, and the associated pathophysiological changes. Finally, we offer perspectives on the existing challenges of using NPs as theranostic agents and possible futuristic approaches to improve them.

Compared to its past structure, Turkey is now a country with low levels of fertility and mortality. This junction that Turkey now has reached is associated with a number of risks, such as an ageing population, and a decreasing working-age population. The antinatalist policy era of Turkey was followed by a period of maintenance, yet the recent demographic changes formed the basis of a pronatalist population policy from the government’s view. This study discusses the link between demographic change and population policies in Turkey. It further aims to position Turkey spatially in relation to selected countries that are in various stages of their demographic transitions with different population policies, using a multidimensional scaling approach with data on 25 selected countries from the UN. The analysis is based on a 34-year period, 1975-2009, so as to better demonstrate Turkey’s international position on a social map, past and present. Our findings suggest that Turkey’s position on the social map shifted towards developed countries over time in terms of demographic indicators and population policies.

Artery Disease

In the US, a total of 23.6 million people have diabetes, representing 7.8% of the population, and the prevalence of diabetes is on the rise due to an increasingly sedentary lifestyle, increasing obesity and an ageing population. Coronary artery disease is the leading cause of death in patients with diabetes, despite a reduction in cardiovascular events over the last 50 years, due in part to better medical therapy. Asymptomatic diabetic patients with evidence of ischaemia on stress testing have higher cardiac mortality; increasing amounts of ischaemia are associated with higher mortality rates. Revascularisation of high-risk patients, or those with significant ischaemia, has the potential to improve outcomes in this patient population. The choice of which revascularisation strategy to choose – either percutaneous coronary intervention (PCI) or coronary artery bypass grafting – should be carefully individualised, and must always be implemented against the background of optimal medical therapy.

Infectious diseases remain a major health problem and cause of death worldwide. It is expected that the socio-economic impact will further intensify due to escalating resistance to antibiotics, an ageing population and an increase in the number of patients under immunosuppressive therapy and implanted medical devices. Even though radiolabeled probes and leukocytes are routinely used in clinical practice, it might still be difficult to distinguish sterile inflammation from inflammation caused by bacteria. Moreover, the majority of these probes are based on the attraction of leukocytes which may be hampered in neutropenic patients. Novel approaches that can be implemented in clinical practice and allow for swift diagnosis of infection by targeting the microorganism directly, are posing an attractive strategy. Here we review the current strategies to directly image bacteria using radionuclides and we provide an overview of the preclinical efforts to develop and validate new approaches. Indeed, significant progress has been made in the past years, but very few radiopharmaceuticals (that were promising in preclinical studies) have made it into clinical practice. We will discuss the challenges that remain to select good candidates for imaging agents targeting bacteria.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder recognized as the most common cause of chronic dementia among the ageing population. AD is histopathologically characterized by progressive loss of neurons and deposits of insoluble proteins, primarily composed of amyloid-β pelaques and neurofibrillary tangles (NFTs). Methods: Several molecular processes contribute to the formation of AD cellular hallmarks. Among them, post-translational modifications (PTMs) represent an attractive mechanism underlying the formation of covalent bonds between chemical groups/peptides to target proteins, which ultimately result modified in their function. Most of the proteins related to AD undergo PTMs. Several recent studies show that AD-related proteins like APP, Aβ, tau, BACE1 undergo post-translational modifications. The effect of PTMs contributes to the normal function of cells, although aberrant protein modification, which may depend on many factors, can drive the onset or support the development of AD. Results: Here we will discuss the effect of several PTMs on the functionality of AD-related proteins potentially contributing to the development of AD pathology. Conclusion: We will consider the role of Ubiquitination, Phosphorylation, SUMOylation, Acetylation and Nitrosylation on specific AD-related proteins and, more interestingly, the possible interactions that may occur between such different PTMs.

BACKGROUND The constant progression in number and share of the ageing population will likely have deep effects in most of the industrialized countries. The Internet of Things (IoT) paradigm can play a key role in facilitating independent living of the ageing population thus trying to reduce the burden on the society. Considering that ageing is a multi-factorial physiological process, the development of novel IoT systems, tools and devices, specifically targeted to older people, must be based on a holistic framework built on robust scientific knowledge in different scientific domains. OBJECTIVE A novel semantic formalization was developed, based on a multidomain healthy ageing model, to support structuring and standardizing heterogeneous scientific knowledge about ageing. The main aim of the paper is to present the new NESTORE ontology, with the purpose thus extending the available ontologies provided by universAAL-IoT (uAAL-IoT). METHODS Well-assessed scientific knowledge, specifically selected to target older adults aged between 65 and 75, was formalized into a holistic model using a multi-domain approach including three main different dimensions related to well-being: (i) Physiological Status and Physical Activity Behaviour, (ii) Nutrition, and (iii) Cognitive and Mental Status and Social Behaviour. Based on this model, within the NESTORE H2020 project, a new ontology was developed in the uAAL-IoT framework, which provides modelling tools and a set of core ontologies. RESULTS The NESTORE ontologies cover all the needed concepts to represent 5 significant domains of ageing. In total, 12 sub-ontologies were modelled with more than 60 classes and sub-classes referenced among them by using more than 100 relations and around 20 enumerations. NESTORE increases the uAAL ontologies collection by 40% and expand the uAAL domain usage for Physiological Status and Physical Activity Behaviour (8 ontologies), Nutrition (3 ontologies) and Cognitive and Mental Status and Social Behaviour (4 ontologies). CONCLUSIONS NESTORE ontology provides innovation both in terms of semantic content and technological approach. The thoroughly use of this ontology can support the development of a decision support system, to promote healthy ageing, with the capacity to do dynamic multi-scale modelling of user-specific data based on the semantic annotations of users’ profile.
