An innovative colorimetric sensing strategy was developed for the detection of glucose by the integration of glucose aptamer, glucose oxidase (GOx), and horseradish peroxidase (HRP), termed aptamer proximal enzyme cascade reactions (APECR). In the presence of glucose, aptamer binding enables GOx to catalyze glucose oxidation into HO efficiently. Subsequently, the adjacent HRP catalyzes the oxidation of the peroxidase substrate, 2,2'-biazobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), utilizing the generated HO, resulting in a distinct color change. In comparison to the free enzymes and the HRP-GOx system, APECR exhibited higher colorimetric signal. This approach achieved glucose detection within three minutes, which was significantly faster than previous methods. This method showed good sensitivity and selectivity with a limit of detection of 0.013 mM. Moreover, the practical utility of this strategy was verified by achieving rapid detection of glucose in clinical serum samples. Hence, the developed strategy has the advantages of simple operation and rapid analysis time for the detection of glucose in human serum.

Background: The current study investigated the effects of high-fat diet on acute response to 3,4-methylenedioxypyrovalerone (MDPV) in mice. MDPV is a beta-cathinone derivative endowed with psychostimulant activity. Similarly to recreational substances, consumption of palatable food stimulates the mesolimbic dopaminergic system, resulting in neuroadaptive changes.

Background: It has been revealed that the potential utility of the triglycerides and glucose (TyG) index as an effective option for assessing glycemic control; however, evidence in this field is still scarce.
Aims: The goal of this study was to investigate the diagnostic accuracy of the TyG index, as an alternative option, to detect inadequate glycemic control in patients with type 2 diabetes (T2D).
Methods: Men and women between 30 and 60 years of age diagnosed with type 2 diabetes were included in a cross-sectional study.

The implanted Eversense Continuous Glucose Monitoring (CGM) System transitioned from 90- to 180- to 365-day durations marketed today. This report summarizes the 365-day clinical study. ENHANCE was a prospective, multicenter study evaluating the accuracy and safety of the Eversense 365 CGM system through 1 year in adults with diabetes.

Spectrophotometer method, ELISA, and High-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) method have been widely used to quantify and characterize the glucose released from rice after in vitro digestion. Despite this, the results of the three methods may not be comparable. This work investigated the limitation of detection (LOD) and quantification (LOQ) of the glucose released after in vitro rice digestion.

Predicting the onset of type 1 diabetes mellitus (T1D) in patients treated with immune checkpoint inhibitors (ICI) remains challenging. ICI-induced T1D (ICI-T1D) is a rare but serious complication that leads to complete insulin depletion. While diabetes-associated autoantibodies, such as glutamic acid decarboxylase antibodies (GADA), are typically absent in non-ICI-related fulminant T1D, they are relatively common in ICI-T1D.
