Effects of Germination on the Fatty Acid, Folate, and Mineral Levels in Quinoa

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
This study analyzed the change of the key nutrients in quinoa during its short‐term germination process. The results showed that germination significantly increases the content of folate, protein, and trace minerals, thereby maximizing its nutritional properties for promoting neural development.

Tetrahydrobiopterin (Bh4) deficiencies: diagnosis and treatment

Acta Pediátrica de México, 2014
Tetrahydrobiopterin (BH4) is an enzyme cofactor of phenylalanine hydroxylase, tyrosine hydroxylase and tryptophan hydroxylase. Three different enzymes affect BH4 synthesis: guanosine triphosphate cyclohydrolase I (GTP CH 1), 6-piruvoil tetrahydropterin ...

Ultraviolet-induced fluorescent imaging for millipede taxonomy [PDF]

Research Ideas and Outcomes, 2017
Fluorescent imaging has been traditionally applied to cell biology, and more recently to entomology to capture microscopic images of insect anatomy. However, the technique has not been applied to the study of millipedes, most of which autofluoresce as a ...

Reversal Potential of Multidrug Antibiotic Resistance in Cutibacterium acnes by Ethanol Extracts of Rhubarb

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
1. Ethanol extract of Rhubarb effectively reversed regular clinical antibiotic resistance, and was confirmed by growth curves and oxidative markers. 2. Reversal effects were observed with erythromycin (1000‐fold), clindamycin (250‐fold) and tetracycline (2–4‐fold). 3.
