PURPOSE: The clinical course after major burns is characterized by microcirculatory changes and consecutive capillary leakage. However, current clinical monitoring does not properly assess microcirculation, whereas macrohemodynamic changes are continuously evaluated. Here, we assess if macrohemodynamic and microhemodynamic parameters after burn trauma are correlated in a rat model. METHODS: Burn plasma harvested from donor rats 4 hours after thermal injury (30% total body surface area, 100 °C water, 12 seconds) was administered intravenously to healthy animals during 2 hours of intravital microscopy (burn group [BG])...

The diets of farmed salmon are usually supplemented with immunostimulants to improve health status. Because β-glucan is one of the most common immunostimulants used in diets, here we examined the effect of two β-1,3/1,6-glucan-supplemented diets on the expression of immune response genes of Atlantic salmon. The relative abundances of IFN-α1, Mx, IFN-γ, IL-12, TGF-β1, IL-10, and CD4 transcripts were evaluated in head kidney by qRT-PCR. We assessed the effects of the diets under normoxia and acute hypoxia, as salmon are especially sensitive to changes in the concentration of dissolved oxygen, which can also affect immunity...

The KEAP1-NRF2 system is an inducible molecular mechanism enhancing transcriptions of several cytoprotective genes in response to xenobiotics and oxidative stress. Recently, the KEAP1-NRF2 system has been suggested to directly regulate a portion of the genes related to cell proliferation and differentiation. In hematopoietic cells, NRF2 activation plays a role in maintenance and cell fate determination of hematopoietic stem cells, as well as in maturation processes and homeostasis of megakaryocytes and erythrocytes...

A one-pot and scalable synthesis of tetrazolones (tetrazol-5-ones) from acid chlorides using azidotrimethylsilane is presented. The reaction tolerates many functional groups and can furnish aryl-, heteroaryl-, alkenyl-, or alkyl-substituted tetrazolone products in moderate to excellent yield (14-94%). No reduction in yield was observed when the reaction was undertaken on a larger-scale (20-36 g). The method could be used for the late-stage functionalization of pharmaceuticals, to provide tetrazolone congeners of the marketed drugs aspirin, indomethacin, probenecid, telmisartan, bexarotene, niacin (vitamin B3), and the active metabolite of the recently-launched immuno-modulatory agent, BG-12 (Tecfidera(®))...

Unprecedented levels of nitrogen (N) have been deposited in ecosystems over the past century, which is expected to have cascading effects on microbially mediated soil respiration (SR). Extracellular enzymes play critical roles on the degradation of soil organic matter, and measurements of their activities are potentially useful indicators of SR. The links between soil extracellular enzymatic activities (EEAs) and SR under N addition, however, have not been established. We therefore conducted a meta-analysis from 62 publications to synthesize the responses of soil EEAs and SR to elevated N...

A critical challenge for the successful application of antifungal therapies for invasive aspergillosis (IA) is a lack of reliable biomarkers to assess early treatment response. Patients with proven or probable IA were prospectively enrolled, and serial blood samples were collected at 8 specified time points during 12-week antifungal therapy. Total nucleic acid was extracted from 2.5 ml blood and tested for Aspergillus-specific RNA by a pan-Aspergillus real-time nucleic acid sequence-based amplification (NASBA) assay...

BACKGROUND: Glucose sensors measure glucose concentration in the interstitial fluid (ISF), remote from blood. ISF glucose is well known to be "delayed" with respect to blood glucose (BG). However, ISF glucose is not simply a shifted-in-time version of BG but exhibits a more complex pattern. METHODS: To gain insight into this problem, one can use linear systems theory. However, this may lose a more clinical readership, thus we use simulation and two case studies to convey our thinking in an easier way...
