According to OECD, Estonia is one of the EU countries where obesity and diabetes are most prevalent. According to WHO, every fifth child in Estonia is overweight. Therefore, our task is to help people reduce their consumption of sugar, salt, and fat, which are associated with obesity, diabetes, and cardiovascular diseases. The Estonian food industry is already committed to food reformulation, transforming former sinners in to saints. For example, muffin, which has been a delightful dessert in the past, has now become a food with reduced sugar, extra fiber and with a Nutriscore value B. However, its health impact is noticeable only when the taste is equally enjoyable and consumers accept it. This reformulation project explores sweet-tasting and healthy peptides and oligosaccharides to replace added sugars, the synergy of flavor compounds and salt, and the effect of fats on flavour. We aim to have a positive impact on public health without compromising quality, safety and taste.

The project aims to revolutionise biosensors and point-of-care testing devices by developing sensor arrays using Molecularly Imprinted Polymers (MIPs) as biomimetic receptors for multiplex and/or simultaneous detection of targets that are of significant interest to clinical and environmental health. MIPs offer several advantages over traditional biological recognition elements in being more stable, cost-effective, and reproducible, making them ideal for low-cost and fast recognition of clinically relevant biomarkers and environmental pollutants in complex matrices. We will develop novel synthesis approaches for MIP-based sensor arrays that are affordable and scalable, allowing for the production of large quantities of sensors at low cost. Our innovative approach has the potential to establish a new generation of analytical tools that will significantly improve public health and safety, particularly in critical industries such as healthcare and environmental monitoring.

The consumption of dietary fibres (DF) should be increased to comply with the dietary guidelines and fuel various beneficial metabolites produced by the gut microbiota such as short chain fatty acids (SCFA). Microbiota also produces gases that, in sensitive persons including irritable bowel syndrome patients (IBS), trigger disturbing and at worst disabling gastrointestinal (GI) symptoms, leading to the avoidance of fibre-rich foods. The gas formation patterns and amounts are highly individual and interrelated to GI parameters such as gut pH and transit rate. FIBRE-MATCH develops and validates a concept to match DF types to gut microbiome subtypes for optimal metabolic output. The project identifies major DF-metabolising microbiome types prevalent in Europeans using existing metagenomic, dietary and GI symptom data, considering also endogenous glycans. Representative microbiomes and DF will be characterized in vitro to identify metabolic phenotypes. DF combinations yielding an optimal gas to SCFA ratio in vitro will be used to develop fermented food prototypes for proof-of-concept studies in healthy volunteers and IBS patients, to study whether consumption of the microbiome-tailored food improves GI symptoms and IBS markers compared to unmatched fibre, using breath monitoring, metagenome, metabolome and glycan analyses. Biosamples from the healthy subjects will be used to evaluate the effects of DF on risk markers of noncommunicable diseases using metabolomics approaches. A novel database of chemical composition of DF in high-fibre foods will be developed to enable analysis of nutrition-microbiome interactions at functional and molecular level. FIBRE-MATCH fits to the Precision Nutrition Challenge portfolio as it develops fundamental knowledge, capabilities and resources that foster precision nutrition innovations related to individually-tailored microbiome-targeting foods, microbiome-based stratification, and ultimately decreasing the fibre gap.

The overall goal of the project is to increase the number of healthy life years of the population. Currently, Estonia has recorded one of the lowest number of healthy life years at birth in the EU. To achieve this goal, three closely related areas of digital health are researched, developed and piloted. We use the standardized data exchange environment and digital data of the Estonian health information system (EHIS) to develop applications that increase the use of data collected by the person for health promotion, prevention and control of chronic conditions. Second, we focus on sensors and digital applications supported by artificial intelligence (AI) to allow a person to collect both biosignals and textual data in machine-readable form. With this, we speed up the detection of health risks and reduce the healthcare workload. Thirdly, we develop various AI methods by combining the data in EHIS and the Health Insurance Fund's database, as well as the data collected by the person.

This project is based on the new paradigm of "flow as information", a groundbreaking approach for underwater sensing of multiscale flows in Nature. It will lead to new, optimized devices and methods to measure, classify and explore the underwater environment when traditional methods are too expensive or simply do not work. Flow as information is inspired by aquatic animals who have evolved advanced sensory systems which combine sensing and information processing into a single framework. The proposal will advance TalTech's underwater sensing technologies from working prototypes (TRL3 to TRL5) to tests in relevant operational environments (TRL6), and support technology transfer to Estonian and international firms. These devices and methods will provide researchers, industry and authorities with new and reliable sources of flow data during extreme climate and weather events where conventional devices fail and when critical infrastructure is at risk, such as during storm surges and floods.

The importance of antimicrobial membranes has significantly grown during the recent COVID pandemic era. Nanofibrous antimicrobial membranes have seen novel applications in biomedicine, such as face masks against viral threats or wound dressings used in chronic patient care. Composite electrospun nanofiber meshes are convenient to use as antimicrobial membranes. At present, the lack of automated, inline quality control limits both the pilot and large scale production of multi-material multilayer composite membranes. The alternative, manual re-calibration greatly limits production throughput and thus commercial viability. The goal of this R&D activity is to create technology for scalable inline quality control of electrospun nanofiber meshes. Using cognitive electronics, the system will be capable of continuous multiparameter monitoring and electrospinning process control to maintain optimal product quality and distribution.

The general goal is the development of electronic devices for clinical measurement of soft tissues. Specific result is a device for continuous monitoring of the condition of the heart muscle during heart surgery. Heart disease is the most common cause of death (WHO 2019, https://www.who.int/news-room/fact-sheets/detail/the-top-10-causes-of-death). Surgery plays an important role in the treatment of advanced heart diseases, with a risk of damage to the muscle (of a stopped heart!) during surgery. Current heart protection methods are poorly controlled, as based on schemes developed by trial and error. The unique solution being created will ensure the real-time usage of protective solutions based on objective heart muscle indicators. The technology being created, also allows measuring of various other muscle, fat and connective tissues, and could also distinguish benign and malignant tissues. The solutions created use inventive electrical impedance spectroscopy technologies of TalTech.

Sensing, capturing and separating enantiomers is important for environmental safety, agricultural chemistry, and drug design. The use of hemicucurbiturils is an effective strategy because of the combination of various monomers in a single-step templated mechanochemical synthesis. Due to the absence of bulk solvent the self-organizing efficiency is amplified and there is less waste - the process is green and sustainable. The current work will study the fundamentals of self-organization of hemicucurbiturils, the binding (capturing) of chiral molecules, and detecting chirality using supramolecular complexes. In the long term, the empirical observations will be combined with results from computational chemistry and cheminformatics to build models for predicting necessary monomers and reaction conditions to form macrocycles with desired properties. The outcomes of the project are expected to be highly useful for organizations and industries that monitor, use, or manufacture chiral compounds

The aforementioned three thematic work packages contribute together with the remaining four (monitoring and prognosis of Ida-Viru employment, development of Ida-Viru technology intensive innovation niches, vulnerability of local population and innovation potential, health impacts of transition and development of health services) to the development of the transition processes framework and are implemented in cooperation with UT research teams.

The nervous system consists of multiple cell types with distinct physiological specializations and gene expression patterns. In tissue, these cells form a complex, intertwined network that is subject to constant interaction between different cell types. This complexity poses a challenge for researchers in both separating cell types for analysis as well as studying interactions and information transfer between cells. In this application, we propose a molecular neuroscience study addressing both aspects. First, we are developing proteomics methods to allow analysis of newly synthesized proteins on a cell type-specific basis. Second, we shall use novel genetic tools for cell type-specific stimulation and gene expression analysis in primary co-cultures of neurons and astroglial cells. We shall use this system to probe gene expression signatures in neuron-astrocyte communication and determine the transmitters that form the basis of this communication.

Cellulose is the most common biopolymer in the world, which can replace fossil-based plastics and fibers. However, cellulose-based plastics only account for 0.2% and man-made fibers for 1% of the world's production of plastics and non-natural textile fibers. Cellulose needs chemical modification to make these products. Until now, industry has been limited by environmental impact and cost of the process. Cellulose is also the most important biomaterial for Estonia, but industrial cellulose chemistry is limited here. At the same time, this industry gives the highest added value to cellulose. As the biorefineries, output of which is cellulose, are vigorously developing in Estonia, this project develops technology of reactive extrusion, with which cellulose can be valorized in a sustainable manner using residues from production of vegetable oils. The project strengthens cooperation between companies and academy, increases competence in the field, and contributes to academic succession.

Customization requirements in modern manufacturing demand a closer collaboration between operators and automated technologies, leading to a novel Human-Robot Collaboration (HRC) and interaction (HRI) paradigm aimed at augmenting human capabilities in the workplace. Digital Twin (DT) and Immersive technologies (XR) support the inclusion of the human operator in simulation-based interfaces intended for safe, efficient, multimodal, and adaptive HRI. The design and implementation of these interfaces are not yet adequately addressed. This project aims to define what is the current approach to the requirement definition for DT and XR by analyzing the potentials and challenges of the adoption of DT interfaces and other types of input methods in the HRC context, their allocation in the Human-Computer Interaction (HCI), and the state of current experimental research in this field as bringing the human back to the loop bring us the Industry 5.0 concept within industrial and healthcare domains

Projekt OptimaMind keskendub ajapiiranguga söömisele, et parandada aju tervist ja võidelda vananemisega kaasnevate väljakutsetega. Ajalooliselt oli inimeste juurdepääs toidule sageli juhuslik, muutes vahelduva paastumise (teise nimega aeg-restrikteeritud söömise (TRE)) elu loomulikuks osaks. See ajalooline kontekst loob aluse TRE võimalike eeliste mõistmiseks tänapäeval, eriti kognitiivse tervise kontekstis. On näidatud, et TRE kutsub esile adaptiivseid molekulaarseid muutusi, mis kaitsevad rakuressursse, parandades samal ajal füüsilist ja kognitiivset jõudlust. Sellised muutused hõlmavad süsteemse põletiku vähenemist ja raku antioksüdantide potentsiaali suurenemist. Üks TRE mõju näidetest on beeta-hüdroksübutüraadi (BHB), ketoonkeha, mis parandab kognitiivseid funktsioone, tootmine. Maksas toodetud BHB on oluline energiasubstraat, millel on võrreldes teiste energiaallikatega kasulikumaid omadusi. Ja vastupidi, sagedane toidutarbimine ja vähene füüsiline aktiivsus võivad pärssida BHB tootmist, vähendades seega selle positiivset mõju. Projekti OptimaMind eesmärk on uurida erinevate meetodite abil TRE mõju kognitiivsete funktsioonide biomarkeritele, eriti vananevas elanikkonnas. Kavandatavas projektis kasutatakse Euroopas olemasolevaid biopankade proove ja erinevaid paastuprotokolli kohordi andmeid, et uurida neuroprotektiivseid biomarkereid erinevates populatsioonides. Oodatavad tulemused hõlmavad uusi teadmisi TRE-st kui mittefarmakoloogilisest strateegiast kognitiivse pikaealisuse suurendamiseks ja dementsuse ennetamiseks. Projekti eesmärk on ka teavitada tervishoiuteenuse osutajaid ja avalikkust praktilistest tõenduspõhistest strateegiatest aju tervise säilitamiseks. OptimaMind mõjutab rahvatervise soovitusi, kliinilisi tavasid ja heaolutööstust, mille eesmärk on lõpuks parandada kognitiivset tervist ja elukvaliteeti vananevas elanikkonnas.
