MetabolomicsAn ambient-temperature storage and stabilization device performs comparably to flash-frozen collection for stool metabolomics in infants

BACKGROUND: Stool metabolites provide essential insights into the function of the gut microbiome. The current gold standard for storage of stool samples for metabolomics is flash-freezing at - 80 °C which can be inconvenient and expensive. Ambient temperature storage of stool is ...

MetabolomicsMaternal steroids during pregnancy and their associations with ambient air pollution and temperature during preconception and early gestational periods
Hormones play critical roles in facilitating pregnancy progression and the onset of parturition. Several classes of environmental contaminants, including fine particulate matter (PM2.5) and ambient temperature, have been shown to alter hormone biosynthesis or activity. However, epidemiolo...

MetabolomicsSeawater Analysis by Ambient Mass Spectrometry-Based Seaomics

A transmission mode-direct analysis in real time-quadrupole time of flight-mass spectrometry (TM-DART-QTOF-MS)-based analytical method coupled to multivariate statistical analysis was developed to interrogate lipophilic compounds in seawater samples without the need of desalin...

MetabolomicsEvaluation of ambient mass spectrometry tools for assessing inherent postharvest pepper quality

Horticulturists are interested in evaluating how cultivar, environment, or production system inputs can affect postharvest quality. Ambient mass spectrometry approaches enable analysis of minimally processed samples under ambient conditions and offer an attractive high-throughput alternative for ...

MetabolomicsApplication of HPLC-PDA-MS metabolite profiling to investigate the effect of growth temperature and day length on blackcurrant fruit
INTRODUCTION: Blackcurrant (Ribes nigrum L.) is an excellent example of a “super fruit” with potential health benefits. Both genotype and cultivation environment are known to affect the chemical composition of blackcurrant, especially ascorbic acid and various phenolic compounds. Environmental condi...

MetabolomicsElevated temperature accelerates leaf senescence and promotes leaf nitrogen transport to improve rice grain protein synthesis
Elevated temperatures during grain filling severely constrain rice yield and quality. Although additional nitrogen can mitigate the adverse effects of elevated temperature, both factors increase grain protein content, and the underlying physiological mechanisms remain poorly understood. Here, we con...

TranscriptomicsMeasurement of temperature affects on Arabidopsis transcription and decay rates
The goal of this study is to measure Arabidopsis mRNA transcription and mRNA decay rates genome wide at two temperatures, and thus to calculate the temperature coefficient of both processes. Sensing and response to ambient temperature is important for controlling growth and development of many organ...

TranscriptomicsThe effects of leptin deficiency on cold-induced energy expenditure
At 24 °C Lep-/- mice are hyperphagic compared to the Lep+/+ mice. Reducing the ambient temperature from 24 to 6 °C (3 °C per day) was accompanied by a graded parallel increase in food intake in both control and Lep-/- mice. The rate of increase in food intake per degree Celsius reduction in ambient ...

TranscriptomicsPost-natal development of brown adipocytes in white fat: Phases independent and dependent of the ambient temperature
Decreased ambient temperature, from birth to weaning, significantly reduced fat mass (FM) and adiposity in developing mice. Changes in FM content in 10 day-old mice raised at 17°C were not accompanied by precocious induction of brown adipocytes in inguinal white adipose tissue (WAT). Brown phenotype...
