Tethering ferredoxin-NADP+ reductase to photosystem I promotes photosynthetic cyclic electron transfer.

Fixing CO2 via photosynthesis requires ATP and NADPH, which can be generated through linear electron transfer (LET). However, depending on the environmental conditions, additional ATP may be required to fix CO2, which can be generated by cyclic electron transfer (CET). How the balance between LET and CET is determined remains largely unknown.

Assisted reproduction and the fetal malformation risk associated with antiseizure medication exposure in pregnancy.

Objective: This study was undertaken to explore the possible role of assisted reproduction treatment (ART) in the occurrence of fetal malformation in women with antiseizure medication (ASM)-treated epilepsy.

Methods: Data collected in the Australian Pregnancy Register of Antiepileptic Drugs concerning the pregnancies of women with ASM-treated epilepsy were analyzed using standard simple statistical methods.

Results: The malformed fetal occurrence rate tended to be higher in women with epilepsy (WWE) treated with ASMs than in those untreated in at least the earlier months of pregnancy, the risk being statistically significantly higher (p < .

Metabolism of hemicelluloses by root-associated Bacteroidota species.

Bacteroidota species are enriched in the plant microbiome and provide several beneficial functions for their host, including disease suppression. Determining the mechanisms that enable bacteroidota to colonise plant roots may therefore provide opportunities for enhancing crop production through microbiome engineering. By focusing on nutrient acquisition mechanisms, we discovered Bacteroidota species lack high affinity ATP-binding cassette transporters common in other plant-associated bacteria for capturing simple carbon exudates.

Resonant Vibrational Enhancement of Downhill Energy Transfer in the -Phycocyanin Chromophore Dimer.

Energy transfer between electronically coupled photosynthetic light-harvesting antenna pigments is frequently assisted by protein and chromophore nuclear motion. This energy transfer mechanism usually occurs in the weak or intermediate system-bath coupling regime. Redfield theory is frequently used to describe the energy transfer in this regime.

Soft X-ray spectromicroscopic proof of a reversible oxidation/reduction of microbial biofilm structures using a novel microfluidic in situ electrochemical device.

In situ electrochemistry on micron and submicron-sized individual particles and thin layers is a valuable, emerging tool for process understanding and optimization in a variety of scientific and technological fields such as material science, process technology, analytical chemistry, and environmental sciences. Electrochemical characterization and manipulation coupled with soft X-ray spectromicroscopy helps identify, quantify, and optimize processes in complex systems such as those with high heterogeneity in the spatial and/or temporal domain. Here we present a novel platform optimized for in situ electrochemistry with variable liquid electrolyte flow in soft X-ray scanning transmission X-ray microscopes (STXM).
