The muscle–intervertebral disc interaction mediated by L-BAIBA modulates extracellular matrix homeostasis and PANoptosis in nucleus pulposus cells

open access: yesExperimental and Molecular Medicine
Upon engaging in physical activity, skeletal muscle synthesizes myokines, which not only facilitate crosstalk with various organs, including the brain, adipose tissue, bone, liver, gut, pancreas, and skin but also promote intramuscular signaling ...

Integrated Metabolome and Microbiome Analysis Reveals the Regulatory Effects of Fermented Soybean Meal on the Gut Microbiota of Late Gestation

open access: yesFermentation
Late gestation is a critical period for regulating maternal peripartum physiological metabolism and gut microbiota balance. Fermented diets have been widely recognized as effective exogenous nutritional interventions capable of modulating the maintenance

Fungal Peptaibiotics: Assessing Potential Meteoritic Amino Acid Contamination [PDF]

open access: yes, 2010
The presence of non-protein alpha-dialkyl-amino acids such as alpha-aminoisobutyric acid (alpha-A1B) and isovaline (Iva), which are relatively rare in the terrestrial biosphere, has long been used as an indication of the indigeneity of meteoritic amino ...

Searching for Extraterrestrial Amino Acids in a Contaminated Meteorite: Amino Acid Analyses of the Canakkale L6 Chondrite [PDF]

open access: yes
Amino acids can serve as important markers of cosmochemistry, as their abundances and isomeric and isotopic compositions have been found to vary predictably with changes in parent body chemistry and alteration processes.

The Impact and Oxidation Survival of Selected Meteoritic Compounds: Signatures of Asteroid Organic Material on Planetary Surfaces [PDF]

open access: yes, 2013
Polar, non-volatile organic compounds may be present on the surfaces (or near surfaces) of multiple Solar System bodies. If found, by current or future missions, it would be desirable to determine the origin(s) of such compounds, e.g., asteroidal or in ...

Stapled truncated orexin peptides as orexin receptor agonists [PDF]

open access: yes, 2018
The peptides orexin-A and -B, the endogenous agonists of the orexin receptors, have similar 19-amino-acid C-termini which retain full maximum response as truncated peptides with only marginally reduced potency, while further N-terminal truncations ...

Beta-Aminoisobutyric Acid, A Possible Factor in Pyrimidine Metabolism.

open access: yesExperimental Biology and Medicine, 1951
Summary(1) A compound frequently noted in a chromatographic study of urinary amino acids has now been isolated from the urines of two cancer patients and identified as beta-aminoisobutyric acid (BAIB). (2) In a group of 140 apparently healthy subjects, 52 individuals showed detectable urinary levels of BAIB (>0.15 millimole per liter), and three of ...
