Dealing With the Complexity of Effective Population Size in Conservation Practice.

Effective population size () is one of the most important parameters in evolutionary biology, as it is linked to the long-term survival capability of species. Therefore, greatly interests conservation geneticists, but it is also very relevant to policymakers, managers, and conservation practitioners. Molecular methods to estimate rely on various assumptions, including no immigration, panmixia, random sampling, absence of spatial genetic structure, and/or mutation-drift equilibrium.

Current landscape of clinical use of ex vivo expanded natural killer cells for cancer therapy.

Natural Killer cells are immune leukocytes required for responses against tumor cells and virus-infected cells. In the last decade, natural killer cells have emerged as promising tools in cancer therapy, and clinical studies on patients treated with natural killer cells have revealed increased rates of disease-free survival. In this article, we review results from the major clinical trials that have used natural killer cells for cancer treatment, including their global distribution.

Early Results of Fenestrated and Branched Endovascular Repair of Complex Aortic Aneurysms with a Custom-made National Device Available in the Brazilian Public Health System.

Background: Multicenter studies conducted in developed countries demonstrated that custom-made devices are safe, effective, and durable for treating complex abdominal aneurysms. However, the situation in developing countries, such as Brazil, is different. Funding and time to have the endoprosthesis delivered are the major concerns.

Trust in government moderates the association between fear of COVID-19 as well as empathic concern and preventive behaviour.

With the COVID-19 pandemic, behavioural scientists aimed to illuminate reasons why people comply with (or not) large-scale cooperative activities. Here we investigated the motives that underlie support for COVID-19 preventive behaviours in a sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease with support towards preventive COVID-19 behaviours would be moderated by trust in the government.
