We studied the effect of bone marrow cells (BMC) and nanosecond repetitively pulsed microwaves (RPMs, 10 GHz, pulse duration 100 nsec, pulse repetition rate 8 Hz, peak power flux density (pPFD) 140 W/cm) on the regeneration of thermally damaged skin in rats. The combined use of BMC and RPMs accelerates separation of an eschar with its complete rejection on day 14 of the experiment. Histological analysis demonstrated a statistically significant increase in the relative area of the granulation tissue and thickness of newly formed epidermis in the group with combined exposure.

- The study aims to improve the diagnosis and treatment of congenital heart diseases by examining the relationship between hemodynamic parameters and the structure of the thoracic aorta.
- Researchers utilized multi-slice spiral CT images of the aorta from patients with and without heart issues to create numerical models and estimate hemodynamic features using fluid dynamics techniques.
- A metamodel was developed that accurately classifies different aorta types, indicating that structural measurements can reliably predict hemodynamic characteristics, and this approach can be applied to other heart conditions as well.
The COVID-19 pandemic has triggered several changes in countries' health purchasing arrangements to accompany the adjustments in service delivery in order to meet the urgent and additional demands for COVID-19-related services. However, evidence on how these adjustments have played out in low- and middle-income countries is scarce. This paper provides a synthesis of a multi-country study of the adjustments in purchasing arrangements for the COVID-19 health sector response in eight middle-income countries (Armenia, Cameroon, Ghana, Kenya, Nigeria, Philippines, Romania and Ukraine).

We estimated excess deaths associated with the pandemic in Ukraine during 2020 and 2021. Excess deaths may be attributed directly to SARS-CoV-2 infection or indirectly to deaths associated with social and economic upheavals resulting from the pandemic.

Whether these taxes negatively impact domestic sugar producers, an argument often made by opponents, is understudied. We extended a simulation model based on a uniform specific volume-based tax of UAH 4/L in Ukraine.
