Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

open access: yesAngewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Ketone Bodies Inhibit the Opening of Acid-Sensing Ion Channels (ASICs) in Rat Hippocampal Excitatory Neurons in vitro

open access: yesFrontiers in Neurology, 2019
Objectives: Despite the long-term efficacy of antiepileptic drug treatments, frequent attacks of drug-resistant epilepsy necessitate the development of new antiepileptic drug therapy targets.

Measurement of β-hydroxybutyrate in cats with nonketotic diabetes mellitus, diabetic ketosis, and diabetic ketoacidosis [PDF]

open access: yes, 2011
Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes mellitus (DM). The standard method of detection of ketone bodies is the dipstick method, which detects semiquantitatively acetoacetate, but not β-hydroxybutyrate (β-HB).

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

open access: yesAdvanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Very‐low‐carbohydrate diet enhances human T‐cell immunity through immunometabolic reprogramming

open access: yesEMBO Molecular Medicine, 2021
Very‐low‐carbohydrate diet triggers the endogenous production of ketone bodies as alternative energy substrates. There are as yet unproven assumptions that ketone bodies positively affect human immunity.

Genetic Relationship of Body Energy and Blood Metabolites with Reproduction in Holstein Cows [PDF]

open access: yes, 2008
Body condition score (BCS), energy content (EC), cumulative effective energy balance (CEEB), and blood serum concentrations of glucose, beta-hydroxybutyrate (BHBA), and nonesterified fatty acids ( NEFA) were measured throughout first lactation in 497 ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Understanding the aqueous phase ozonolysis of isoprene: distinct product distribution and mechanism from the gas phase reaction [PDF]

open access: yes, 2012
The aqueous phase reaction of volatile organic compounds (VOCs) has not been considered in most analyses of atmospheric chemical processes. However, some experimental evidence has shown that, compared to the corresponding gas phase reaction, the aqueous ...
