Fully Automated Deep Learning Enabled Miniature Mass Spectrometry System for Psychoactive Therapeutic Drug Monitoring

open access: yesAdvanced Science, EarlyView.
This study presents a fully automated miniature mass spectrometry system for high‐throughput therapeutic drug monitoring. Integrating magnetic solid‐phase extraction, self‐aspiration sampling miniature mass spectrometer, and U‐net deep learning quantitative algorithm, it achieves rapid (8 samples/30 min), precise (R2 > 0.99, RSD < 10%), and portable ...

Phosphorus availability and speciation in the fertosphere of three soils over 12 months

open access: yesGeoderma
Identifying the effects of soil properties on the transformations of phosphorus (P) in highly concentrated fertiliser bands is a critical component in improving P fertiliser use efficiency, but little is known regarding the kinetics of P transformation ...

Glucose‐Responsive PAGR1‐Regulated Skeletal Muscle Gene Program Controls Systemic Glucose Homeostasis and Hepatic Metabolism

open access: yesAdvanced Science, EarlyView.
The study reveals that PAXIP1‐associated glutamate‐rich protein 1 (PAGR1), a glucose‐responsive regulator in skeletal muscle, modulates systemic glucose homeostasis and hepatic metabolism. Muscle‐specific PAGR1 deletion enhances insulin signaling, promotes glucose transporter 4 (GLUT4) translocation, and protects against high‐fat‐diet‐induced insulin ...

Targeted Intervention Strategies for Maternal–Offspring Transmission of Christensenellaceae in Pigs via a Deep Learning Model

open access: yesAdvanced Science, EarlyView.
This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Biological Nitrogen Fixation by Local and Improved Genotypes of Cowpea in Burkina Faso (West Africa): Total Nitrogen Accumulated can be used for Quick Estimation

open access: yesAdvances in Agriculture, 2018
Biological nitrogen fixation (BNF) by legumes is an indicator of their potential contribution to recycling nitrogen in cropping systems. Many techniques exist for the quantitative measurement of legume BNF. The isotopic dilution (ID) methods are the most

Unraveling Tissue‐Specific Fatty Acid Biosynthesis and Inter‐Tissue Crosstalk in Mice through Stable‐Isotope Tracing Metabolomics

open access: yesAdvanced Science, EarlyView.
Biosynthesis rates of 13 FFAs are quantitatively calculated in 15 tissues from glucose and an analytical framework to quantitatively calculate inter‐tissue communications of fatty acids between the liver and other tissues is developed. Moreover, the approach is extended to aging condition and a system‐wide decline of fatty acid synthesis in peripheral ...

Isotope determination of sulfur by mass spectrometry in soil samples Determinação isotópica de enxofre por espectrometria de massas (irms) em amostras de solo

open access: yesRevista Brasileira de Ciência do Solo, 2012
Sulphur plays an essential role in plants and is one of the main nutrients in several metabolic processes. It has four stable isotopes (32S, 33S, 34S, and 36S) with a natural abundance of 95.00, 0.76, 4.22, and 0.014 in atom %, respectively. A method for
