Postpartum development of type 1 diabetes in Asian Indian women with gestational diabetes.

Aim: To study the postpartum conversion of gestational diabetes mellitus (GDM) to different types of diabetes among Asian Indian women.

Materials And Methods: Using data from electronic medical records, 418 women with GDM seen at a tertiary diabetes care center for diabetes in Chennai in South India between 1991 and 2014 were evaluated for development of diabetes postpartum.

Results: Of the 418 GDM women followed up postpartum, 388 progressed to diabetes.

Vibrational, UV spectra, NBO, first order hyperpolarizability and HOMO-LUMO analysis of carvedilol.

In this work, we have investigated experimentally and theoretically on the molecular structure, vibrational spectra, UV spectral analysis and NBO studies of cardio-protective drug carvedilol. The FT-Raman and FT-IR spectra for carvedilol in the solid phase have been recorded in the region 4000-100 cm(-1) and 4000-400 cm(-1) respectively. Theoretical calculations were performed by using density functional theory (DFT) method at B3LYP/6-31G(d,p) and B3LYP/6-31++G(d,p) basis set levels.

Investigation of silicate mineral sanidine by vibrational and NMR spectroscopic methods.

Sanidine, a variety of feldspar minerals has been investigated through optical absorption, vibrational (IR and Raman), EPR and NMR spectroscopic techniques. The principal reflections occurring at the d-spacings, 3.2892, 3.

Vibrational spectral investigation on xanthine and its derivatives--theophylline, caffeine and theobromine.

A normal coordinate analysis has been carried out on four compounds having a similar ring structure with different side chain substitutions, which are xanthine, caffeine, theophylline, and theobromine. Xanthine is chemically known as 2,6-dihydroxy purine. Caffeine, theophylline and theobromine are methylated xanthines.
