Cyanobacteria and algae having complex photosynthetic systems can channelize absorbed solar energy into other forms of energy for production of food and metabolites. In addition, they are promising biocatalysts and can be used in the field of "white biotechnology" for enhancing the sustainable production of food, metabolites, and green energy sources such as biodiesel. In this review, an endeav...

Intracerebral microdialysis (MD) was applied in patients with subarachnoid hemorrhage. The regional CBF, the CMRO2, and oxygen extraction ratio (OER) were measured with simultaneous positron emission tomography (PET). The aim was to directly correlate alterations in dialysate levels of energy-related metabolites (lactate, lactate/pyruvate ratio, hypoxanthine) and excitatory amino acids (EAAs) (...

To further optimize the culturing of preimplantation embryos, we undertook metabolomic analysis of relevant culture media using capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS). We detected 28 metabolites: 23 embryo-excreted metabolites including 16 amino acids and 5 media-derived metabolites (e.g., octanoate, a medium-chain fatty acid (MCFA)). Due to the lack of informatio...

Military training studies provide unique insight into metabolic responses to extreme physiologic stress induced by multiple stressor environments, and the impacts of nutrition in mediating these responses. Advances in metabolomics have provided new approaches for extending current understanding of factors modulating dynamic metabolic responses in these environments. In this study, whole-body me...

With more than 25 million people affected, heart failure (HF) is a global threat. As energy production pathways are known to play pivotal role in HF, we sought here identify key metabolic changes ischemic- and non-ischemic HF by using multi-OMICS approach. Serum metabolites mRNAseq epigenetic DNA methylation profiles were analyzed from blood left ventricular biopsy specimens of the same individ...

Meloidogyne incognita is a common root-knot nematode with a wide range of plant hosts. We aimed to study the metabolites produced at each stage of the nematode life cycle to understand its development. Metabolites of Meloidogyne incognita were extracted at egg, J2, J3, J4, and female stages and 110 metabolites with available standards were quantified using CE-TOF/MS. Analyses indicated abundanc...

Metabolites and enzyme activities involved in energy metabolism in Taenia solium cysticerci were determined systematically in vivo in order to illustrate the principles of variation of energy metabolism. Metabolites and enzymes determined included GLC, LAC, PEPCK, PK, LDH, SDH, ICD, XOD, ME, GDH, FR, ATPase, ACP, AKP, G6Pase and FE. The results showed that transport of substances, anaerobic gly...

Background: Fatty acid mobilization and inflammatory response of adipose tissues vary in various depots, hence the response of fat-tailed and thin-tailed sheep breeds to different energy balances was hypothesized to be different due to differences in proportion and metabolism of various adipose depots in these breeds which may affect whole body insulin sensitivity. Objective: Current study aime...
