Results of 69 aortocoronary bypass operations with the use of microsurgery equipment were analysed. Perfusion was performed under conditions of constant flow, which made it possible to avoid transmissive pulsation, making difficulties for creating microanastomoses. One venous double opening canule was used with no drainage of the left ventricule, which made cannulation easier and created optimal technical conditions for the surgeon. Duration of extracorporeal blood circulation and frequency of intraoperational complications (cardiac failure, myocardial infarction) depended on the operational methods: initial creation of proximal anastomoses resulted in decreased duration of the perfusion, improved protection of myocardium and lower number of complications.

Are Non-invasive Multi-cancer Early Cancer Detection Tests the Future?

Current cancer screening methods are effective for detecting early stage cancers and even preventing some cancers, but their effectiveness has only been demonstrated for a handful of cancers, and for many cancers, there are no screening tests clinically available. In addition, the majority of the screening methods are not ideal, resulting in suboptimal compliance and the occurrence of preventable cancers. A screening test that is convenient, safe, accurate and that can screen for multiple cancers is an ideal screening test that would address many of the shortcomings of the current tests.

The critical need for rapid cancer diagnosis and related illnesses is growing alongside the current healthcare challenges, unfavorable prognosis, and constraints in diagnostic timing. As a result, emphasis on surface-enhanced Raman spectroscopy (SERS) diagnostic methods, including both label-free and labelled approaches, holds significant promise in fields such as analytical chemistry, biomedical science, and physics, due to the user-friendly nature of SERS. Over time, the SERS detection sensitivity and specificity with nanostructured materials for SERS applications (NMs-SERS) in different media have been remarkable.

The unprecedented sequencing efforts during the COVID-19 pandemic paved the way for genomic surveillance to become a powerful tool for monitoring the evolution of circulating viruses. Herein, we discuss how a state-of-the-art artificial intelligence approach called protein language models (pLMs) can be used for effectively analyzing pathogen genomic data. We highlight examples of pLMs applied to predicting viral properties and evolution and lay out a framework for integrating pLMs into genomic surveillance pipelines.
