Foliar methane and nitrous oxide fluxes in Salix bebbiana respond to light and soil factors

Communications Earth & Environment
Foliar exchange of methane and nitrous oxide is a significant yet poorly understood component of global greenhouse gas budgets. To address this knowledge gap, we investigated foliar methane and nitrous oxide fluxes in Salix bebbiana, under varying light ...

Probing stratospheric transport and chemistry with new balloon and aircraft observations of the meridional and vertical N2O isotope distribution [PDF]

, 2006
A comprehensive set of stratospheric balloon and aircraft samples was analyzed for the position-dependent isotopic composition of nitrous oxide (N2O). Results for a total of 220 samples from between 1987 and 2003 are presented, nearly tripling the number

Toward Prostate Cancer Early Warning with a Self‐Powered Wearable Biosensing Platform Integrated with Machine Learning

Advanced Science, EarlyView.
ABSTRACT Current prostate cancer detection methods remain limited in non‐invasiveness and specificity, prompting interest in urinary biomarkers such as sarcosine. Here, we report a urine‐powered wearable platform for non‐invasive sarcosine detection as a proof‐of‐concept for decentralized early warning.

Immediate Recovery of Psychomotor Function After Patient-Administered Nitrous Oxide/Oxygen Inhalation for Colonoscopy

, 1997
Background and Study Aims: Previous studies have shown that patients inhaling self-administered nitrous oxide/oxygen as a sedative/analgesic medication for colonoscopy were ready to leave the endoscopy unit on average sooner than those given conventional

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Acute psychotic and vitamin B12 deficiency in patient with nitrous oxide misuse: A case report

SAGE Open Medical Case Reports
Nitrous oxide, also called nitrous monoxide, or nitrous oxide, is a colorless and odorless gas, without toxicological effect, but it can be asphyxiating at high concentration, its misuse is increasing especially among young people.

On the origin of nitrous oxide and its oxygen [PDF]

, 2010
Lachgas (N2O) is een broeikasgas dat bijdraagt aan de opwarming van de aarde en de afbraak van ozon in de stratosfeer. Om emissies van N2O terug te dringen zullen we moeten begrijpen hoe en waar het ontstaat.

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...
