Performance of the 1 h oral glucose tolerance test in predicting type 2 diabetes and association with impaired β-cell function in Asians: a national prospective cohort study.

Background: Postprandial glucose concentration 1-h (1 h-PG) after an oral glucose tolerance test (OGTT) has similar or superior performance to 2 h-PG in predicting type-2 diabetes mellitus (T2DM) in several populations, and is simpler to obtain in clinical practice. However, studies in Asians are scarce. We investigated the utility of elevated baseline 1 h-PG in predicting T2DM incidence within three years, and its relationship with β-cell function in 1250 non-diabetic Asian participants.

Cerebral perfusion alterations in healthy young adults due to two genetic risk factors of Alzheimer's disease: APOE and MAPT.

Functional brain changes such as altered cerebral blood flow occur long before the onset of clinical symptoms in Alzheimer's disease (AD) and other neurodegenerative disorders. While cerebral hypoperfusion occurs in established AD, middle-aged carriers of genetic risk factors for AD, including APOE ε4, display regional hyperperfusion due to hypothesised pleiotropic or compensatory effects, representing a possible early biomarker of AD and facilitating earlier AD diagnosis. However, it is not clear whether hyperperfusion already exists even earlier in life.

ADME, Toxicity, Molecular Docking, Molecular Dynamics, Glucokinase activation, DPP-IV, α-amylase, and α-glucosidase Inhibition Assays of Mangiferin and Friedelin for Antidiabetic Potential.

Today the alarming situation of diabetes seeks innovative antidiabetic medications, especially those derived from natural sources, as natural substances are safer than manufactured pharmaceuticals. Therefore, this study investigated the inhibitory properties of mangiferin and friedelin against glucokinase (GK), dipeptidyl peptidase-IV (DPP-IV), α-amylase, and α-glucosidase using computational methods, in vitro enzyme assays, and in-depth ADMET analysis. The study utilized a computer-aided drug design approach to assess the potential therapeutic properties of mangiferin and friedelin as Type 2 diabetes mellitus (T2DM) therapeutic agents.
