We will be developing the cloud data platform which will host the data, processes and in-silico machine working model for the project.</em></p> <p>People are continuously exposed to a huge amount and variety of potentially toxic chemicals present in the surrounding environment, such as <strong>pesticides</strong> or <strong>drugs traces in water, soil, air and living organisms</strong>. The combined action of pollutants can increase the risk of toxic effects. At the same time, a <strong>growing occurrence of cardiovascular diseases has been observed. These diseases have been among the top-ranked causes of death in mature and aged populations for the last 30 years.</strong> Scientists think that this increase may be related to the environmental exposure to exogenous toxic chemicals.<br> ALTERNATIVE (environmentAL Toxicity chEmical mixtuRes through aN innovative platform based on aged cardiac tissue model) project, coordinated by <strong>Prof. Gianluca Ciardelli</strong> with the Biomedical Lab team <strong>(Susanna Sartori, Monica Boffito)</strong> from <strong>DIMEAS-Department of Mechanical and Aerospace Engineering</strong> of Politecnico, will produce <strong>an innovative in vitro platform able to evaluate the cardiotoxicity of single chemicals or a mixture of chemical components.</strong> The platform is made by a tri-dimensional model of bioengineered human functional cardiac tissue cultured in a bioreactor, together with a system allowing <strong>“omic” analysis to understand the response of the model to different substances. Artificial Intelligence algorithms will be implemented to estimate the risk.</strong> Additionally, the project will develop a model of aged cardiac tissue to evaluate <strong>the impact of toxics on the fragile population.</strong><br> The model will be initially validated on existing toxicity data and after it will be used to make predictions on chemical and pharmaceutical substances. This project aims at finding impact also at regulatory level. The European bodies responsible for <strong>regulating chemicals such as fertilizers or detergents, industrial chemicals or pharmaceutical products</strong> are seeking an exhaustive evaluation of the toxicity of single substances or mixtures. ALTERNATIVE proposes a new method to make this information available for what concerns cardiotoxicity, allowing to <strong>obtain more reliable results with a viable technology</strong> which will have a lower impact on the environment and minimize ethical concerns through the <strong>reduction of animal testing.</strong><br> This project has been financed in the framework of the <strong>European Green Deal Actions</strong> and put together different expertise (<em>in silico</em> systems, machine learning algorithms, toxicology, epidemiology, regulatory affairs) to deliver, in the end, <strong>increased awareness of cardiovascular risks related to pollutants</strong> (a poorly investigated field so far). A significant support to the regulatory framework for the management of the production and disposal of chemicals and pharmaceuticals is also expected.</p>http://cst-bg.net/projects/alternative/Wed, 06 May 2026 11:37:34 +0300http://cst-bg.net/projects/alternative/<p>Project Type: Horizon 2020 research project</p> <p>Date: 2021 - 2025</p> <p>ALTERNATIVE will develop an innovative platform able to detect the cardiotoxicity of chemicals and their biotransformation products. The novel platform will enable regulators and industry to identify, quantify and prevent cardiotoxic co-exposures to industrial chemicals and pharmaceuticals in a cost-effective way. ALTERNATIVE will particularly focus on cardiotoxic effects on the older people, which is of high relevance in view of the aging European population and the high spread of cardiovascular diseases.</p>http://cst-bg.net/clients/client-two/Wed, 06 May 2026 11:37:34 +0300http://cst-bg.net/clients/client-two/http://cst-bg.net/services/devops-as-a-service/Tue, 05 May 2026 10:10:00 +0200http://cst-bg.net/services/devops-as-a-service/<p>Harness the transformative power of DevOps with CST, a team of experts wholly dedicated to empowering organizations through innovative IT infrastructure enhancements and efficient automation strategies.</p> <p>Our offerings go beyond the typical DevOps services, covering:</p> <ul> <li> <p>Tooling and IT Infrastructure Management</p> </li> <li> <p>Infrastructure as Code (IaC) Implementation using Terraform, Ansible, Cluster-API, and Crossplane</p> </li> <li> <p>Comprehensive Configuration Management</p> </li> <li> <p>Advanced Linux Administration</p> </li> <li> <p>Network Security and Management</p> </li> <li> <p>CI/CD Pipelines, Release Management, and Automation</p> </li> <li> <p>Containerization Solutions: Orchestration and migration from monolithic architectures to modern containerized systems</p>http://cst-bg.net/projects/gaiax/Wed, 06 May 2026 11:37:34 +0300http://cst-bg.net/projects/gaiax/<p>Project Type: Next generation of data infrastructure: an open, transparent and secure digital ecosystem, where data and services can be made available, collated and shared in an environment of trust</p> <p>Date: 2022 - 2023</p> <p>GAIA-X Federation Services includes the building of basic services for connected, open data infrastructure based on european standards and values.

And while using more than one provider is great in some situations by itself, it still lacks the integration between those providers which applications need in order to form a coherent and highly flexible solution. A multi-cloud solution without integration means that software cannot easily communicate, share state, and is not governed by the same policy rules. In this post I will explore the different aspects of cloud integration, what benefits it provides beyond basic multi-cloud and why I think it is the next natural evolution of multi-cloud.</p>http://cst-bg.net/services/consulting/Tue, 05 May 2026 10:10:00 +0200http://cst-bg.net/services/consulting/<h4 id="expert-consulting-services-for-your-company">Expert Consulting Services for Your Company​</h4> <p>In the fast-paced world of software development, keeping up with the latest technologies and methodologies can be a challenging task.

While portability has different aspects, all of which must be considered, it can be split in two components - the application itself and the environment where the application is running. To achieve portability you need both, an application which is designed to be portable and a new environment which is compatible with the application.</p>http://cst-bg.net/services/blockchain/Tue, 05 May 2026 10:10:00 +0200http://cst-bg.net/services/blockchain/<h4 id="blockchain-development-services-powering-digital-trust">Blockchain Development Services: Powering Digital Trust​</h4> <p>In the world where data is the new currency, trust is the key to successful transactions.

It&rsquo;s success is largely due to its power, flexibility, distributed mode of operation and ability to manage extremely complex projects with multiple developers collaborating on the same code-base. However, Git has a steep learning curve which make it hard for many developers to effectively take advantage. Using Git without understanding of its underlying architecture in detail, can be dangerous. Therefore my argument here is that when starting with Git, developers should invest the time to quickly become expert by understanding how Git is designed, implemented and what each of the commands does in the database. Alternatively, knowing just a little bit of Git can be a problem because you use a powerful tool and can cause a lot of problems for you and the rest of the team.</p>http://cst-bg.net/services/cloud-multicloud-iot/Tue, 05 May 2026 10:10:00 +0200http://cst-bg.net/services/cloud-multicloud-iot/<p>In a rapidly evolving digital landscape, the strategic advantage lies with those who can harness the power of technology to transform their business processes.

Companies are leveraging this technology by migrating legacy application from on-premise data centers to public cloud and are developing new software solutions using a cloud-native principles. Next to established cloud architectures like private, public and hybrid-cloud some companies are also looking forward multi-cloud solutions, which is the use of multiple public cloud providers at once. In this post we want to help you decide if and why should your company develop a multi-cloud strategy by looking at the driving factors behind multi-cloud and how this technology can solve problems that the other approaches cannot.</p>http://cst-bg.net/careers/Wed, 06 May 2026 11:37:34 +0300http://cst-bg.net/careers/<h3 id="careers-at-cst">Careers at CST</h3> <h4 id="join-our-team">Join Our Team</h4> <p>At CST, we are always on the lookout for talented, passionate, and innovative individuals to join our team.
