J Heart Lung Transplant 2021 Jun 24;40(6):405-413. Epub 2021 Mar 24.

Lasker Clinical Research Tenure Track Investigator and Laboratory Chief, Laboratory of Applied Precision Omics, National Heart, Lung, and Blood Institute, Bethesda, Maryland; Lung Transplantation Program, Johns Hopkins School of Medicine, Baltimore, M. Electronic address:

Cell-free DNA, measured as donor-derived cell-free DNA is developed as a non-specific biomarker for allograft injury and transplant rejection. However, cell-free DNA characteristics are more specific, its fragment length, nucleotide content, and composition, as well as the tissue source of origin, are intrinsically linked to the underlying disease pathogenesis, showing distinct features in acute cellular rejection and antibody-mediated rejection for example. Further, cell-free DNA and cell-free mitochondrial DNA can directly trigger tissue injury as damage-associated molecular patterns through three major intracellular receptors, toll-like receptor 9 , cyclic guanosine monophosphate-adenosine monophosphate synthase, and inflammasomes (i.

Zentralbl Chir 2021 Jun 13;146(3):269-276. Epub 2021 Apr 13.

Klinik- und Poliklinik für Allgemein-, Viszeral-, Thorax- und Gefäßchirurgie, Universitätsklinikum Bonn, Deutschland.

Introduction: In recent years, perioperative care of patients after colorectal surgery has been increasingly standardised according to the fast-track concept and is accepted as a structured method of care to reduce perioperative complications. Indeed, initial studies have indicated that there is a long-term favourable effect on the oncological outcome, if the adherence to the individual measures is at least 70%. Even though there is unambiguous evidence for the efficacy of the modern perioperative treatment concept, it is often difficult to comply with the protocol during normal clinical work, particularly in Germany.

Toward net-zero sustainable aviation fuel with wet waste-derived volatile fatty acids.

Proc Natl Acad Sci U S A 2021 Mar;118(13)

Catalytic Carbon Transformation Center, National Renewable Energy Laboratory, Golden, CO 80401;

With the increasing demand for net-zero sustainable aviation fuels (SAF), new conversion technologies are needed to process waste feedstocks and meet carbon reduction and cost targets. Wet waste is a low-cost, prevalent feedstock with the energy potential to displace over 20% of US jet fuel consumption; however, its complexity and high moisture typically relegates its use to methane production from anaerobic digestion. To overcome this, methanogenesis can be arrested during fermentation to instead produce C to C volatile fatty acids (VFA) for catalytic upgrading to SAF. Read More
