Do sandy beaches accumulate nitrogen?

Marine Ecology Progress Series, 1986
A moderate-energy sandy beach receiving a hlgh natural organic load of stranded wrack was studied over 1 yr. Nitrogen input to the beach was calculated from wrack nitrogen content, an average standing stock of 72 kg m-' wet wrack and a turnover time of 9 d, estimated from litter bag (2mm mesh) experiments.

Xenon expenditure and nitrogen accumulation in closed‐circuit anaesthesia [PDF]

Anaesthesia, 2001
The high price of xenon has prevented its use in routine, clinic anaesthetic practice. Xenon therefore has to be delivered by closed‐circuit anaesthesia. The accumulation of nitrogen is a significant problem within the closed circuit and necessitates flushing, which in turn increases gas expenditure and costs.

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

FEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Gas exchange and organic matter production of Scots pine (Pinus sihestris L.) seedlings grown in water culture with ammonium or nitrate form of nitrogen

Acta Societatis Botanicorum Poloniae, 2015
he reaction of Scots pine (Pinus silvestris L.) seedlings to ammonium and nitrate form of nitrogen was investigated. Rates of photosynthesis and respiration, content of chlorophylls, and accumulation of organic substance were determined in 12 and 18 ...

Metabolic network changes during skotomorphogenesis in Arabidopsis thaliana mutant (atdfb‐3)

Plant Direct, 2022
The metabolic networks underlying skotomorphogenesis in seedlings remain relatively unknown. On the basis of our previous study on the folate metabolism in seedlings grown in darkness, the plastidial folylpolyglutamate synthetase gene (AtDFB) T‐DNA ...

Modeling nitrogen accumulation and use by soybean

Field Crops Research, 2003
Abstract Simulation of soybean growth and yield requires an accurate representation of nitrogen accumulation and distribution in the developing crop. Approaches to simulate nitrogen accumulation by soybean have been complicated by the need to account for both soil nitrate uptake and symbiotic nitrogen fixation.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

The accumulated APCs in vps21Δ cells entered vacuoles after prolonged nitrogen starvation.

, 2022
A. The accumulated GFP-Atg8-labeled APCs observed in vps21Δ cells gradually entered vacuoles during prolonged nitrogen starvation. The indicated cells expressing GFP-Atg8 (as in Fig 1E) were grown in YPD medium as described in Fig 1A to an OD600 value of

Effect of different NPK fertilization timing sequences management on soil-petiole system nutrient uptake and fertilizer utilization efficiency of drip irrigation cotton

Scientific Reports, 2023
In order to elucidate the effects of different nitrogen (N), phosphorus (P), and potassium (K) fertilization timing sequences management on nutrient absorption and utilization in drip irrigation cotton, field experiments were conducted from 2020 to 2021.
