Use of cold for preservation of biological materials, avoidance of food spoilage and to manage a variety of medical conditions has been known for centuries. The cryobiological science justified these applications in the 1960s increasing their use in expanding global activities. However, the engineering and technological aspects associated with cryobiology can be expensive and this raises questions about the abilities of resource-restricted low and middle income countries (LMICs) to benefit from the advances. This review was undertaken to understand where or how access to cryobiological advances currently exist and the constraints on their usage. The subject areas investigated were based on themes which commonly appear in the journal Cryobiology. This led in the final analysis for separating the review into two parts, with the first part dealing with cold applied for biopreservation of living cells and tissues in science, health care and agriculture, and the second part dealing with cold destruction of tissues in medicine. The limitations of the approaches used are recognized, but as a first attempt to address these topics surrounding access to cryobiology in LMICs, the review should pave the way for future more subject-specific assessments of the true global uptake of the benefits of cryobiology.

Two critical factors for obtaining high viable biological samples after cryopreservation by vitrification method are cryoprotectant glass-forming ability while cooling and the stability of its amorphous state during warming. The present work is devoted to the study of the amorphous state stability of plant vitrification solutions (PVS) by differential scanning calorimetry method. The objects of the study were PVS1 modified, PVS2, PVS3 modified, PVS4 and PVSN. The thermograms of PVSs, frozen in liquid nitrogen, were recorded at a warming rate of 0.5 deg/min. The glass transition temperatures of PVS1, PVS2 and PVS3 were –109.0°C, –115.3°C, and –93.9°C, respectively. Neither exo- nor endothermic peaks have been recorded, indicating no crystallization, at the cooling and the warming stages. PVS4 and PVSN thermograms, besides glass transition (–111.5°C and –110.0°C, correspondingly), showed crystallization from the amorphous state (devitrification) and ice melting peaks. Crystallization enthalpy of PVSN was 2.8 times higher compared to PVS4. This fact testifies that the crystalline phase was larger in PVSN compared to PVS4. It should be noted that crystallization in PVS4 and PVSN may be related to the low warming rate used during the experiment. At higher warming rates, this crystallization is likely to be avoided. Thus, PVS1, PVS2 and PVS3 have a high glass-forming ability and a stabile amorphous state. The amorphous state stability of PVS4 and PVSN is significantly lower compared to PVS1, PVS2, and PVS3.

Effect of Cryopreserved Placental Explants on Female Reproductive System Under Normal and Pathological Conditions (Experimental study)

Background and Aim: The One Health approach integrates human, animal, plant, and environmental health through multisectoral collaboration and is increasingly recognized as essential for addressing zoonotic diseases, antimicrobial resistance (AMR), food security, and ecosystem degradation. Ukraine has formally adopted One Health principles through national strategies and international partnerships; however, the ongoing full-scale military conflict has profoundly disrupted health, veterinary, and environmental systems, challenging effective implementation. This study aimed to evaluate the current status, achievements, and constraints of the One Health approach in Ukraine, with particular emphasis on the effects of armed conflict on governance, surveillance capacity, and intersectoral coordination, and to outline strategic priorities for strengthening One Health resilience. Materials and Methods: A mixed-methods approach was used, combining bibliometric analysis of Scopus-indexed literature on zoonoses, AMR, food security, and environmental safety with targeted case studies and a review of policy documents. National legal frameworks, international guidelines, and reports from global organizations were systematically analyzed to assess institutional capacity and operational readiness. Results: Ukraine has established a solid policy foundation for One Health, notably through the national Strategy for Biosafety and Biosecurity, which is grounded in the One Health principle and aligned with quadripartite frameworks. Active initiatives address priority zoonoses (rabies, leptospirosis, tuberculosis), AMR surveillance, and food safety. Nevertheless, implementation remains fragmented. Armed conflict has caused extensive damage to laboratories, displaced the workforce, created surveillance blind spots, and disrupted multisectoral communication. AMR trends have intensified due to healthcare strain, while environmental and plant health components remain under-integrated despite their relevance to food security and long-term resilience. The Ukrainian experience demonstrates that policy commitment alone is insufficient in the context of conflict. Effective One Health operationalization requires institutionalized governance mechanisms, interoperable surveillance systems, and sustained investment in human resources and laboratory infrastructure. Environmental and plant health integration remains a critical gap. Conclusion: Reinforcing the One Health framework is essential for Ukraine’s recovery and long-term health security. Sustained international technical and financial support, coupled with national institutionalization of One Health principles, is crucial to rebuilding integrated surveillance, mitigating biological risks, and enhancing resilience in conflict-affected settings.
