Evaluation of anti-diabetic effects of glimepiride/metformin cocrystal.

Emerging data suggest that cocrystal of two compounds may have a different pharmacological effect from two compounds alone or their physical combination. Glimepiride (Gli) and metformin (Met) are two types of anti-diabetic drugs. Previously, we generated the glimepiride/metformin cocrystal (GM).

TCF12-regulated GRB7 facilitates the HER2+ breast cancer progression by activating Notch1 signaling pathway.

Background: Human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC), which accounts for approximately one-fifth of all BCs, are highly invasive with a high rate of recurrence and a poor prognosis. Several studies have shown that growth factor receptor-bound protein 7 (GRB7) might be a potential therapeutic target for tumor diagnosis and prognosis. Nevertheless, the role of GRB7 in HER2+ BC and its underlying mechanisms have not been fully elucidated.

INPP4B suppresses HER2-induced mesenchymal transition in HER2+ breast cancer and enhances sensitivity to Lapatinib.

The basic characteristics of the studies and the mechanisms of circRNAs in regulating TNBC chemoresistance were analyzed.

Broadband-excited and green-red tunable emission in Eu-sensitized CaMnTb(PO) phosphors induced by structural-confined cascade energy transfer.

Novel green-red color-tunable Ca(Mg,Mn)Tb(PO):Eu phosphors have been synthesized the traditional solid-state method. Since Tb/Mn ions are the parent ions in the lattice, the structural confinement occurs when the sensitizer Eu is introduced into the Ca(Mg,Mn)Tb(PO):Eu structure. The distance from Eu to Tb/Mn is confined in the 5 Å range, which induces a highly efficient energy transfer process.

Celastrol, a pentacyclic triterpene extracted from the roots of Tripterygium wilfordii Hook F, can reduce insulin resistance and improve diabetic complications.

Purpose: This study aimed to untangle the mechanism of celastrol in ameliorating type 2 diabetes (T2DM) and evaluate its potential benefits as an anti-diabetic agent.

Cardiovascular Complications in Hematopoietic Stem Cell Transplanted Patients.

Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for many patients suffering from hematologic malignancies, solid tumors, inborn errors of metabolism or genetic disorders. Despite decades of successful HSCT, clinical outcomes are still far from satisfactory due to treatment-related complications, including graft-versus-host disease (GvHD) and cardiovascular complications (CVC). CVC may affect patients in the acute period post-HSCT; however, the occurrence is far higher among long-term survivors.
