The Fast Evolution of the Stenobothrini Grasshoppers (Orthoptera, Acrididae, and Gomphocerinae) Revealed by an Analysis of the Control Region of mtDNA, with an Emphasis on the Group.

The two cryptic grasshopper species of the genus , and , demonstrate different acoustic behavior despite a strong similarity in morphology. A hybridization between these species is possible in the contact zone; however, there are little molecular data about the relationships of these species. The analysis of the mtDNA control region (CR) reveals that haplotypes of have more in common with the more distant species than with the closely related .

"…because the social work never ends": a qualitative study exploring how NGOs responded to emerging needs while upholding responsibility to HIV prevention and treatment during the war in Ukraine.

Introduction: Since the onset of the Russian invasion on 24 February 2022, the health system in Ukraine has been placed under tremendous pressure, with damage to critical infrastructure, large losses of human resources, restricted mobility and significant supply chain interruptions. Based on a longstanding partnership between the Ukrainian Institute for Social Research after Oleksandr Yaremenko (UISR after O. Yaremenko) and the Institute for Global Public Health at the University of Manitoba, we explore the impact of the full-scale war on non-governmental organizations (NGOs, including charitable organizations) providing services for key population groups in Ukraine.

Using experience during the COVID-19 pandemic to ensure the quality of PCR studies.

The issues of laboratory diagnostics have been relevant since the first days of the SARS-CoV-2 pandemic and play a key role in the fight against the spread of a new coronavirus infection. A direct method for the etiological diagnosis of the causative agent of COVID-19 is the detection of SARS-CoV-2 RNA using the nucleic acid amplification method. In the context of a pandemic and the mass appeal of patients for medical care, the issues of ensuring the quality of ongoing molecular biological studies at all stages (preanalytical, analytical, postanalytical) become the most relevant.

Statistical properties of extreme soliton collisions.

Synchronous collisions between a large number of solitons are considered in the context of a statistical description. It is shown that, during the interaction of solitons of the same signs, the wave field is effectively smoothed out. When the number of solitons increases and the sequence of their amplitudes decay slower, the focused wave becomes even smoother and the statistical moments get frozen for a long time.

Awareness and Utilization of HIV Testing and Prevention Services Among Female Sex Workers in Dnipro, Ukraine: Implications for Prevention Program Strengthening From the Dynamics Study.

Introduction: Approximately 240,000 people live with HIV in Ukraine, concentrated among key populations, including sex workers. Non-governmental organizations (NGOs) play an important role in the funding and delivery of HIV testing and prevention services in Ukraine. These services are set within the context of national healthcare reforms as well as ongoing armed conflict.
