The dynamics of electric power systems are widely studied through the phase synchronization of oscillators, typically with the use of the Kuramoto equation. While there are numerous well-known order parameters to characterize these dynamics, shortcoming of these metrics are also recognized. To capture all transitions from phase disordered states over phase locking to fully synchronized systems, new metrics were proposed and demonstrated on homogeneous models.

Objectives: This article compares metabolic, pancreatic, and gut-derived hormone responses to isomaltulose ingestion, before versus during submaximal sustained exercise, in adults with type 1 diabetes (T1D) using automated insulin delivery systems.

Methods: In a randomized, cross-over trial, eight participants with T1D being treated with automated insulin pumps (five females, age: 47 ± 16 years, BMI: 27.5 ± 3.

Unlabelled: Background Firearm-related deaths are a substantial public health crisis in America, with studies reporting an increasing rate in the past decade. Effective public health interventions rely on comprehensive information about risk and protective factors.

Aim: This study aims to provide a comprehensive examination of trends in firearm-related deaths over the past 55 years, shedding light on the changing landscape and identifying key risk and protective factors associated with firearm-related deaths in the United States.

Design: The hormone secretin, best known for regulating pH in the duodenum, has anorectic properties in mice proposedly mediated via secretin-induced brown adipose tissue (BAT) activation. We investigated the effects of exogenous secretin on ad libitum food intake, BAT activity, and postprandial physiology in healthy male volunteers.

Methods: In a randomized, placebo-controlled, double-blind, crossover study, 25 healthy men underwent two 5-h i.

Article Synopsis
  • - The study examined gallbladder emptying and GLP-1 hormone responses in women with gestational diabetes mellitus (GDM) during pregnancy and postpartum to understand GDM's impact on these processes.
  • - Twenty women (15 with GDM and 15 with normal glucose tolerance) participated in mixed meal tests, revealing no differences in gallbladder emptying or GLP-1 responses between the two groups during pregnancy or after.
  • - Results showed that while gallbladder volume and emptying increased significantly during pregnancy, GLP-1 responses decreased, indicating that changes in gallbladder function may not be the main factors contributing to reduced GLP-1 levels in women with GDM.
