Aim: Habitat loss and fragmentation impose high extinction risk upon endangered plant species globally. For many endangered plant species, as the remnant habitats become smaller and more fragmented, it is vital to estimate the population spread rate of small patches in order to effectively manage and preserve them for potential future range expansion. However, population spread rate has rarely been quantified at the patch level to inform conservation strategies and management decisions.

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive cancer arising from lymphoblasts of T-cell origin. While TALL accounts for only 15% of childhood and 25% of adult ALL, 30% of patients relapse with a poor outcome. Targeted therapy of resistant and high-risk pediatric T-ALL is therefore urgently needed, together with precision medicine tools allowing the testing of efficacy in patient samples.

Article Synopsis
  • FHR-5 is a protein similar to Factor H, which regulates the immune system's alternative pathway, suggesting it may influence kidney diseases where this pathway is dysfunctional.
  • In a study of 120 patients with diagnosed IC-MPGN and C3G, FHR-5 serum levels were measured, and genetic variants were analyzed to understand their role in disease.
  • Results indicated that 12.6% of patients had genetic variations and that lower serum levels of FHR-5 correlated with better kidney survival and signs of excessive complement activity, suggesting FHR-5 may be important in the disease process.

Vegetation complexity is an important predictor of animal species diversity. Specifically, taller vegetation should provide more potential ecological niches and thus harbor communities with higher species richness and functional diversity (FD). Resource use behavior is an especially important functional trait because it links species to their resource base with direct relevance to niche partitioning.

This article proposes an alternative view of the revolutionary subject. By building on insights from the critical streams of evolutionary psychology, it argues for the notion of revolutionary consciousness to be grounded in the categories of 'exaptive actorness' which are most notably manifested in everyday micropolitics. By emphasising the role of contingency, spontaneity, creativity, resourcefulness and, crucially, formal indeterminism and autonomy, exaptationism emerges as an irreducible and irrevocable enabling tactic of subsistence and subversion, as well as the very essence of the revolutionary act.

Introduction: The randomized PRAGUE-17 trial demonstrated noninferiority of left atrial appendage closure (LAAC) to non-vitamin K anticoagulants (NOACs) for the prevention of major cardiovascular or cerebrovascular events. However, the left atrial appendage is an important source of natriuretic peptides and plays a role in left atrial reservoir function. Changes of heart failure (HF) biomarkers after LAAC compared to NOAC has not been studied.

Species-level environmental niche modeling has been crucial in efforts to understand how species respond to climate variation and change. However, species often exhibit local adaptation and intraspecific niche differences that may be important to consider in predicting responses to climate. Here, we explore whether phylogeographic lineages of the bank vole originating from different glacial refugia (Carpathian, Western, Eastern, and Southern) show niche differentiation, which would suggest a role for local adaptation in biogeography of this widespread Eurasian small mammal.

Serotonin-Its Synthesis and Roles in the Healthy and the Critically Ill.

Int J Mol Sci

May 2021

Department of Internal Medicine, 3rd Faculty of Medicine, Charles University Prague and Teaching Thomayer Hospital, 14059 Prague, Czech Republic.

Serotonin (5-hydroxytryptamine, 5-HT) plays two important roles in humans-one central and the other peripheral-depending on the location of the 5-HT pools of on either side of the blood-brain barrier. In the central nervous system it acts as a neurotransmitter, controlling such brain functions as autonomic neural activity, stress response, body temperature, sleep, mood and appetite. This role is very important in intensive care, as in critically ill patients multiple serotoninergic agents like opioids, antiemetics and antidepressants are frequently used.
