Exploring Models for an International Legal Agreement on the Global Antimicrobial Commons: Lessons from Climate Agreements
Abstract An international legal agreement governing the global antimicrobial commons would represent the strongest commitment mechanism for achieving collective action on antimicrobial resistance (AMR). Since AMR has important similarities to climate change—both are common pool resource challenges that require massive, long-term political commitments—the first article in this special issue draws lessons from various climate agreements that could be applicable for developing a grand...

The Antiphospholipid Syndrome ‐often overlooked cause of vascular occlusions?
Abstract The antiphospholipid syndrome (APS) was fully recognized as a clinical entity in the early 1980’s. Still, more than 30 years later, the epidemiology of APS is not well described and furthermore APS remains a challenge in terms of both diagnostic issues and clinical praxis involving a wide range of specialties. To date there are no diagnostic criteria for APS. The present classification criteria rely on a combination of clinical manifestations and persistently positive tests for...

The role of the microbiota in sedentary life style disorders and ageing: Lessons from the animal kingdom
Abstract A paradox of so‐called developed countries is that, as the major historical causes of human mortality are eliminated or mitigated by medical progress, life‐style related diseases have become major killers. Furthermore, as life‐span is extended by the combined effects of modern medicine, health‐span is struggling to keep apace because of the burden of non‐communicable diseases linked to diet and sedentary life‐style.

Comparative Transcriptome Analysis of the Heat Stress Response in Monochamus alternatus Hope (Coleoptera: Cerambycidae)
Temperature is a critical factor of insect population abundance and distribution. Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a significant concern since it is transmitted vector of the pinewood nematode posing enormous economic and environmental losses. This pest shows tolerance to heat stress, especially extremely high temperatures. Exposing for 6, 12, 24, 48, or 96 h, the 50% median lethal temperatures (Ltem50) for fourth-instar larvae were 47.5, 45.5, 43.9, 43.4, and 42.3°C, respectively....

Increased Hepcidin Levels During a Period of High Training Load Do Not Alter Iron Status in Male Elite Junior Rowers
The liver-derived hormone hepcidin plays a key role in iron metabolism by mediating the degradation of the iron export protein ferroportin 1 (FPN1). Circulating levels of hepcidin and the iron storage protein ferritin are elevated during the recovery period after acute endurance exercise, which can be interpreted as an acute phase reaction to intense exercise with far-reaching consequences for iron metabolism and homeostasis. Since absolute and functional iron deficiency (ID) potentially lead to...

Knockdown of SLC38 Transporter Ortholog – CG13743 Reveals a Metabolic Relevance in Drosophila
Solute Carrier (SLC) is a cluster of families of membrane bound transporters, of which many members lack defined substrate profile, and many more are poorly characterized. Many play a vital role in regulating metabolic systems, protein synthesis, and post translational modifications. SLC38 is one of the families of SLCs, which are also known as sodium-coupled neutral amino acid transporters (SNATs). In mice, it has 11 members (SNAT1-11) but in Drosophila there are two homologs for the SLC38 family;...

Acute Increase in O-GlcNAc Improves Survival in Mice With LPS-Induced Systemic Inflammatory Response Syndrome
Sepsis is a systemic inflammatory response syndrome (SIRS) resulting from a severe infection that is characterized by immune dysregulation, cardiovascular derangements, and end-organ dysfunction. The modification of proteins by O-linked N-acetylglucosamine (O-GlcNAcylation) influences many of the key processes that are altered during sepsis, including the production of inflammatory mediators and vascular contractility. Here, we investigated whether O-GlcNAc affects the inflammatory response and cardiovascular...

It is enclosed by three boundaries: the isometric end-systolic relation, the work-loop (shortening) end-systolic relation, and the zero-active stress isotonic end-systolic relation....

Alternative Lengthening of Telomeres in Pediatric Cancer: Mechanisms to Therapies
Achieving replicative immortality is a crucial step in tumorigenesis and requires both bypassing cell cycle checkpoints and the extension of telomeres, sequences that protect the distal ends of chromosomes during replication.
