Is photosynthetic enhancement sustained through three years of elevated CO2 exposure in 175-year old Quercus robur?

Tree Physiol 2021 Jul 23. Epub 2021 Jul 23.

Birmingham Institute of Forest Research, University of Birmingham, Edgbaston, B15 2TT, England.

Current carbon cycle models attribute rising atmospheric CO2 as the major driver of the increased terrestrial carbon sink, but with substantial uncertainties. The photosynthetic response of trees to elevated atmospheric CO2 is a necessary step, but not the only one, for sustaining the terrestrial carbon uptake, but can vary diurnally, seasonally and with duration of CO2 exposure. Hence we sought to quantify the photosynthetic response of the canopy-dominant species, Quercus robur, in a mature deciduous forest to elevated CO2 (eCO2) (+150 μmol mol-1 CO2) over the first three years of a long-term free air CO2 enrichment facility at the Birmingham Institute of Forest Research in central England (BIFoR FACE).

Extracellular vesicle miRNA predict FDG-PET status in patients with classical Hodgkin Lymphoma.

J Extracell Vesicles 2021 Jul 15;10(9):e12121. Epub 2021 Jul 15.

Department of Pathology Cancer Center Amsterdam Amsterdam UMC Vrije Universiteit Amsterdam Amsterdam The Netherlands.

Minimally-invasive tools to assess tumour presence and burden may improve clinical management. FDG-PET (metabolic) imaging is the current gold standard for interim response assessment in patients with classical Hodgkin Lymphoma (cHL), but this technique cannot be repeated frequently. Here we show that microRNAs (miRNA) associated with tumour-secreted extracellular vesicles (EVs) in the circulation of cHL patients may improve response assessment. Read More

Oral pre-treatment with thiocyanate (SCN) protects against myocardial ischaemia-reperfusion injury in rats.

Sci Rep 2021 Jun 16;11(1):12712. Epub 2021 Jun 16.

The Heart Research Institute, Newtown, NSW, 2042, Australia.

Despite improvements in revascularization after a myocardial infarction, coronary disease remains a major contributor to global mortality. Neutrophil infiltration and activation contributes to tissue damage, via the release of myeloperoxidase (MPO) and formation of the damaging oxidant hypochlorous acid. We hypothesized that elevation of thiocyanate ions (SCN), a competitive MPO substrate, would modulate tissue damage. Read More

Salicylic acid pre-treatment modulates Pb-induced DNA damage vis-à-vis oxidative stress in Allium cepa roots.

Environ Sci Pollut Res Int 2021 May 17. Epub 2021 May 17.

Department of Botany, Panjab University, Chandigarh, 160 014, India.

The current study investigated the putative role of salicylic acid (SA) in modulating Pb-induced DNA and oxidative damage in Allium cepa roots. Pb exposure enhanced free radical generation and reduced DNA integrity and antioxidant machinery after 24 h; however, SA pre-treatment (for 24 h) ameliorated Pb toxicity. Pb exposure led to an increase in malondialdehyde (MDA) and hydrogen peroxide (HO) accumulation and enhanced superoxide radical and hydroxyl radical levels. Read More
