... The NMR experiment design strategy of NO Relaxation Delay (NORD), introduced mostly as an idealized theoretical approach, is extended and put to practical use by considering synergy and sensitivity-balance in concatenation of experiments. It is illustrated by a novel experiment, NORD {HMBC}–{HSQC}–{TOCSY}, where magnetization of non-¹³C attached protons effectively is channeled from the TOCSY spec ...
metabolomics, etc ; analytical chemistry; secondary metabolites; Show all 3 Subjects
Abstract:
... Microbial metabolomics focuses on the analysis of intracellular or extracellular primary metabolites, signaling molecules, hormones, and secondary metabolites, and it is an important field in systems biology. The progress in microbial metabolomics has been slow primarily due to the complexity and diversity of microbial metabolites, which are usually difficult to identify. However, with the rapid d ...

Abstract:
... This position paper summarizes the current understanding of biological nitrification inhibition (BNI) to identify research needs for accelerating the development of BNI as a N₂O mitigation strategy for grazed livestock systems. We propose that the initial research focus should be on the systematic screening of agronomically desirable plants for their BNI potency and N₂O reduction potential. This r ...

Abstract:
... Polycyclic aromatic hydrocarbons (PAHs) are hazardous environmental pollutants with widespread and well-recognized health concerns. Amidst more than a hundred known PAHs, 16 are categorized as priority pollutants. Use of widely diverse biological machinery comprising bacteria, fungi, and algae harnessed from contaminated sites has emerged as an ecologically safe and sustainable approach for PAH de ...
metabolomics, etc ; metabolites; metabolome; volatile organic compounds; Show all 4 Subjects
Abstract:
... Among the diverse metabolites produced by microbial communities, some are volatile. Volatile organic compounds (VOCs) are vigorously cycled by microbes as metabolic substrates and products and as signaling molecules. Yet, current microbial metabolomic studies predominantly focus on nonvolatile metabolites and overlook VOCs, which therefore represent a missing component of the metabolome. Advances ...

Abstract:
... High-throughput (HTP) plant phenotyping approaches are developing rapidly and are already helping to bridge the genotype–phenotype gap. However, technologies should be developed beyond current physico-spectral evaluations to extend our analytical capacities to the subcellular level. Metabolites define and determine many key physiological and agronomic features in plants and an ability to integrate ...

Abstract:
... Generating comprehensive and high-fidelity metabolomics data matrices from LC/HRMS data remains to be extremely challenging for population-scale large studies (n > 200). Here, we present a new data processing pipeline, the Intrinsic Peak Analysis (IDSL.IPA) R package (https://ipa.idsl.me), to generate such data matrices specifically for organic compounds. The IDSL.IPA pipeline incorporates (1) ide ...

Abstract:
... A new ‘shape-orientated’ continuous wavelet transform (CWT)-based algorithm employing an adapted Marr wavelet (AMW) with a shape matching index (SMI), defined as peak height normalized wavelet coefficient (C′max/H) for feature filtering, was developed for chromatographic peak detection and quantification. Exploiting the chromatographic profile of a candidate peak, AMW-SMI algorithm emphasizes more ...

Abstract:
... Milk is one of the most easily adulterated foods, and the fact that its milk composition is influenced by factors such as animal species and processing methods makes the identification of adulterated dairy products even more challenging. Therefore, there is a need for more accurate, faster and comprehensive techniques to address the problem of dairy product adulteration. As one of the rapidly deve ...

... The NOVA food classification system, divides foods into four categories, namely unprocessed and minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. With the recently increasing pursuit of healthy diets, special attention to minimally processed foods has become crucial. According to NOVA, freshly squeezed, high pressure processing (HPP) and pasteur ...
