Experimental evidence of a pathogen invasion threshold [PDF]

Royal Society Open Science, 2018
Host density thresholds to pathogen invasion separate regions of parameter space corresponding to endemic and disease-free states. The host density threshold is a central concept in theoretical epidemiology and a common target of human and wildlife ...

Dynamics of an experimental microbial invasion [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance Current models for biological invasions are predominantly based on macroorganisms. Few invasion model assumptions have been validated for microbial systems. Further research on microbial invasion dynamics is required to determine whether macrobial models are appropriate for microbes, as well as to understand present and ...

Experimental Study on the Physical Simulation of Water Invasion in Carbonate Gas Reservoirs

Applied Sciences, 2017
Water invasion in carbonate gas reservoirs often results in excessive water production, which limits the economic life of gas wells. This is influenced by reservoir properties and production parameters, such as aquifer, fracture, permeability and ...

EXPERIMENTAL PHOTOGRAPHY AND INVASION

Akdeniz Sanat, 2023
Art that exists in every period of the process has different contents such as materials, techniques, concepts, themes that are far from modern and traditional art practice. Experimental works are the main factors affecting these contents. Although experimental works are mentioned with scientific content, they demonstrate themselves in every field of ...

Genetic Aberrations and Interaction of NEK2 and TP53 Accelerate Aggressiveness of Multiple Myeloma

Advanced Science, 2022
It has been previously shown that (never in mitosis gene A)‐related kinase 2 (NEK2) is upregulated in multiple myeloma (MM) and contributes to drug resistance. However, the mechanisms behind this upregulation remain poorly understood.

Profilin 2 and Endothelial Exosomal Profilin 2 Promote Angiogenesis and Myocardial Infarction Repair in Mice

Frontiers in Cardiovascular Medicine, 2022
Cardiovascular diseases (CVD) are the leading cause of death worldwide, wherein myocardial infarction (MI) is the most dangerous one. Promoting angiogenesis is a prospective strategy to alleviate MI.

RESULTS OF EXPERIMENTAL INVASION OF LABORATORY RATS BY LARVAS OF THE NEMATODA EUSTRONGYLIDES EXICISUS (NEMATODA: DIOCTOPHYMATIDAE) SEPARATED FROM ROACH (RUTILUS RUTILUS, 1758)

Ukrainian Journal of Veterinary Sciences, 2020
The results of experimental invasion of laboratory rats by larvae of the nematode Eustrongylides excisus are presented in the article. The invasions were carried out by nematode larvae, which were selected from a ram caught in the Dnieper-Buhsky estuary.

Blocking glycine utilization inhibits multiple myeloma progression by disrupting glutathione balance

Nature Communications, 2022
The bone tumour microenvironment plays an essential role in multiple myeloma (MM) development. Here, the authors show that bone collagen degradation provides glycine to support MM progression through glutathione and purine synthesis.

Excessive serine from the bone marrow microenvironment impairs megakaryopoiesis and thrombopoiesis in Multiple Myeloma

Nature Communications, 2023
Thrombocytopenia is a major complication in a subset of patients with multiple myeloma (MM). However, little is known about its development and significance during MM. Here, we show thrombocytopenia is linked to poor prognosis in MM.
