Improving the Satellite-Based Winter Wheat Monitoring by Using UAV-Derived Leaf Chlorophyll Content

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mapping regional leaf chlorophyll content (LCC) still faces challenges of the scale mismatch between ground sampling points and satellite pixels. To improve the satellite-based model, this study explored the potential of using high-resolution unmanned ...

Sensitivity Analysis of Carbonate Looping Process Using Twin Fluidized Bed Model

Aerosol and Air Quality Research, 2020
CO2 as the major greenhouse gas plays an important role in environmental problems. Therefore, it is reasonable to find an effective technology for mitigating large CO2 emissions.

ZW4864‐mediated inhibition of the β‐catenin/BCL9/BCL9L complex reveals therapeutic potential in bladder cancer

Molecular Oncology, EarlyView.
BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

Modelling the Present-Day Oceanic Carbon Cycle

, 1993
Carbon dioxide is an important greenhouse gas, and its atmospheric increase causes concern because of a potential impact on the global climate. A prerequisite for assessing possible future climatic changes is a means to estimate the future development of

Evidence for local carbon‐cycle perturbations superimposed on the Toarcian carbon isotope excursion [PDF]

, 2020
A Jurassic negative carbon isotope excursion (CIE), co-evolved with Toarcian Oceanic Anoxic Event (OAE) at ~183 Ma, is suggested to be linked to a global carbon-cycle perturbation and is well documented for Toarcian terrestrial fossil woods and marine ...

Including an ocean carbon cycle model into iLOVECLIM (v1.0) [PDF]

Geoscientific Model Development, 2015
The atmospheric carbon dioxide concentration plays a crucial role in the radiative balance and as such has a strong influence on the evolution of climate.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Degradation changes stable carbon isotope depth profiles in palsa peatlands [PDF]

, 2014
Palsa peatlands are a significant carbon pool in the global carbon cycle and are projected to change by global warming due to accelerated permafrost thaw. Our aim was to use stable carbon isotopes as indicators of palsa degradation.

Extreme drought–accelerated dissolved carbon metabolism triggers pulsed CO₂ outgassing in karst lakes [PDF]

Hydrology and Earth System Sciences
Karst aquatic ecosystems are important reservoirs of dissolved carbon (C), supporting dynamic CO2 fluxes through the biological C pump. However, our current understanding of how sophisticated interactions between aquatic microbiomes and dissolved C ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...
