Background Both sodium glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP4) inhibitors can be used to treat patients with type 2 diabetes mellitus (T2DM) that is inadequately controlled with insulin therapy, and yet there has been no direct comparison of these two inhibitors.

The specific fluorescence properties of morin (3,2',4',5,7-pentahydroxyflavone) were studied in various CH3OH-H2O and CH3CN-H2O mixed solvents. Although the dihedral angle is large in the S0 state, morin has an almost planar molecular structure in the S1 state owing to the very low rotational energy barrier around the interring bond between B and the A, C ring. The excited state intramolecular proton transfer (ESIPT) at the S1 state cannot occur immediately after excitation, S1 → S0 fluorescence can be observed. Two conformers, Morin A and B have been known. At the CH3OH-H2O, Morin B will be the principal species but at the CH3CN-H2O, Morin A is the principal species. At the CH3OH-H2O, owing to the large Franck-Condon (FC) factor for S2 → S1 internal convernal (IC) and flexible molecular structure, only S1 → S0 fluorescence was exhibited. At the CH3CN-H2O, as the FC factor for S2 → S1 IC is small and molecular structure is rigid, S2 → S0 and S1 → S0 dual fluorescence was observed. This abnormal fluorescence property was further supported by the small pK1 value, effective delocalization of the lone pair electrons of C(2')-OH to the A, C ring, and a theoretical calculation.

ObjectiveTo evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke.MethodsTwenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a day with or without mirror therapy for 30 minutes a day were performed under supervision. All groups received conventional occupational therapy for 40 minutes a day for the same period. The CIMT only group and control group also received additional self-exercise to substitute for mirror therapy. The box and block test, 9-hole Pegboard test, grip strength, Brunnstrom stage, Wolf motor function test, Fugl-Meyer assessment, and the Korean version of Modified Barthel Index were performed prior to and two weeks after the treatment.ResultsAfter two weeks of treatment, the CIMT groups with and without mirror therapy showed higher improvement (p<0.05) than the control group, in most of functional assessments for hemiplegic upper extremity. The CIMT combined with mirror therapy group showed higher improvement than CIMT only group in box and block test, 9-hole Pegboard test, and grip strength, which represent fine motor functions of the upper extremity.ConclusionThe short-term CIMT combined with mirror therapy group showed more improvement compared to CIMT only group and control group, in the fine motor functions of hemiplegic upper extremity for the patients with subacute stroke.
