Insights into the subdaily variations in methane, nitrous oxide and carbon dioxide fluxes from upland tropical tree stems.

Recent studies have shown that stem fluxes, although highly variable among trees, can alter the strength of the methane (CH) sink or nitrous oxide (NO) source in some forests, but the patterns and magnitudes of these fluxes remain unclear. This study investigated the drivers of subdaily and seasonal variations in stem and soil CH, NO and carbon dioxide (CO) fluxes. CH, NO and CO fluxes were measured continuously for 19 months in individual stems of two tree species, Eperua falcata (Aubl.

Revised method for constructing acoustic vulnerability curves in trees.

During drought, the formation of air bubbles known as embolisms in the water-conducting xylem reduces hydraulic conductivity, which can ultimately result in tree death. Accurately quantifying vulnerability to embolism formation is therefore essential for understanding tree hydraulics. Acoustic emission (AE) analysis offers a non-destructive method to monitor this process, yet the interpretation of captured signals remains debated.

Arthroscopic Debridement for Treatment of Chronic Dynamic Scaphoid Instability.

 There is a paucity of information on minimal surgical intervention for the treatment of chronic dynamic scaphoid instability (CDSI) that will achieve an acceptable mid-term result.  We hypothesize that by following a debride-first-then-wait protocol, some patients with CDSI can be treated with arthroscopic debridement alone and avoid a reconstructive procedure.  We performed a retrospective, longitudinal study from January 2008 to December 2018 of all patients diagnosed with CDSI and treated with arthroscopic debridement of the scapholunate interosseous ligament.

The nematode effector Mj-NEROSs interacts with Rieske's iron-sulfur protein influencing plastid ROS production to suppress plant immunity.

Root-knot nematodes (RKN; Meloidogyne species) are plant pathogens that introduce several effectors in their hosts to facilitate infection. The actual targets and functioning mechanism of these effectors largely remain unexplored. This study illuminates the role and interplay of the Meloidogyne javanica nematode effector ROS suppressor (Mj-NEROSs) within the host plant environment.

The Impact of a Six-Hour Light-Dark Cycle on Wheat Ear Emergence, Grain Yield, and Flour Quality in Future Plant-Growing Systems.

Cultivating wheat () in a closed environment offers applications in both indoor farming and in outer-space farming. Tailoring the photoperiod holds potential to shorten the growth cycle, thereby increasing the annual number of cycles. As wheat is a long-day plant, a night shorter than a critical length is required to induce flowering.
