Vitamin D supplementation: cholecalciferol, calcifediol, and calcitriol.
Vieth R. Vieth R. Eur J Clin Nutr. 2020 Nov;74(11):1493-1497. doi: 10.1038/s41430-020-0697-1. Epub 2020 Jul 23. Eur J Clin Nutr. 2020. PMID: 32704098 Review.
In nature, by far the major form of vitamin D that nurtures the body is cholecalciferol. In contrast, ergocalciferol is primarily a synthetic and less stable product which is less potent per microgram dose than is cholecalciferol. ...Recent evidence shows that ergoc …

Expanded Vermiculite/D-Mannitol as Shape-Stable Phase Change Material for Medium Temperature Heat Storage.
Lv X, Fan C, Han Y, Tang X, Zhang C, Cai D, Chen H. Lv X, et al. Materials (Basel). 2023 Sep 7;16(18):6101. doi: 10.3390/ma16186101. Materials (Basel). 2023. PMID: 37763379 Free PMC article.
After impregnating D-mannitol into the CV carrier by vacuum, a melting enthalpy of 205.1 J/g and a crystallization enthalpy of 174.1 J/g were achieved by the as-received CV/D-mannitol ss-PCM. Additionally, the supercooling of the ss-PCM was reduced to 45.6 C. The no …

Is type-D a stable construct? An examination of type-D personality in patients before and after cardiac surgery.
Dannemann S, Matschke K, Einsle F, Smucker MR, Zimmermann K, Joraschky P, Weidner K, Köllner V. Dannemann S, et al. J Psychosom Res. 2010 Aug;69(2):101-9. doi: 10.1016/j.jpsychores.2010.02.008. Epub 2010 Apr 10. J Psychosom Res. 2010. PMID: 20624508
RESULTS: Preoperatively, 26% were assessed to have type-D, while only 11% fulfilled type-D criteria both pre- and post-surgery. Patients were assessed and identified as belonging to one of the four type-D groups: Stable type-D (11%), non-type- …

Chirality from D-guanosine to L-guanosine shapes a stable gel for three-dimensional cell culture.
Du Y, Liu T, Tang F, Jin X, Zhao H, Liu J, Zeng X, Chen Q. Du Y, et al. Chem Commun (Camb). 2021 Dec 3;57(96):12936-12939. doi: 10.1039/c9cc09911e. Chem Commun (Camb). 2021. PMID: 34734933
It is proved that L-guanosine (L-G) as an enantiomer of D-guanosine (D-G) forms more stable gels than D-G, suggesting that alteration of chirality may be a new strategy for improving the lifetime stability of supramolecular hydrogels. ...
