Summary: Researchers have identified a FOXL1+ intestinal subepithelial network of telocytes (TCs) that play a crucial role in the proliferation and regeneration of epithelial stem and progenitor cells. These FOXL1+ lineage cells are found not only along the intestinal epithelium, but also within the muscle layers. The study suggests that there is a mutual origin for TCs and smooth muscle cells (SMCs).

Summary: This paper investigates the dynamics of coupled cell assemblies to understand the spontaneous generation of electrical activity in tissues without specialized pacemaker cells. The findings demonstrate that these assemblies exhibit a wide range of behaviors, including chaos, but when embedded in a lattice, they produce spatial-temporal patterns corresponding to quiescent states or synchronized oscillations. These patterns can be reproduced by a simplified model with only excitatory and oscillatory elements.

Summary: This study preliminarily explored the association between muscularis macrophages (MM phi) and achalasia. The findings showed that patients with achalasia had fewer interstitial cells of Cajal (ICC) and higher levels of M1 macrophages in the lower esophageal sphincter (LES). There were significant correlations between M2/MM phi and the numbers of ICC and glial cells, suggesting that MM phi may be associated with the occurrence and development of achalasia.

Summary: The contraction activation of smooth muscle in the stomach wall (SW) is coordinated by slow electrical waves initiated and propagated by interstitial cells of Cajal (ICC). This model integrates a biophysically based model of ICC pacemaker activity and a mechanical feedback mechanism to simulate gastric slow waves induced by abnormal stretching of the antral SW. The model predicts stretch-induced gastric arrhythmias, such as the emergence of an ectopic pacemaker in the gastric antrum.

Summary: The primary challenge in generating spherical images is controlling the plausibility and wideness of the generated images. Researchers propose a method that incorporates scene symmetry to estimate the possible symmetry range and generate various plausible spherical images by combining symmetric transformations of NFOV image features.

Summary: Loss of interstitial cells of Cajal (ICC) and aging are associated with higher gastric slow wave velocity, but the exact reasons for these relationships are still unknown. Increased slow wave velocity may modulate gastric emptying higher, although in gastroparesis other pathological factors must dominate to prevent emptying.

Summary: With the development of industrial video technology, the use of cameras for anomaly detection in industrial products has gained attention. In this study, an unsupervised ensemble detection method based on image enhancement is proposed. It utilizes pseudo-anomaly images and pseudo-labels to guide the training process. The method shows improvements in performance in various real datasets.

Summary: A novel automated method for measuring whole gut transit time in mice was developed, utilizing high definition cameras capturing time-lapse videos for offline analysis. The results demonstrated that the loperamide group with delayed transit showed slowed transit compared to the control group, supporting the feasibility of this automated approach and raising discussions on traditional methods.

Summary: In this study, we demonstrate that the electrogenic Na+/HCO3- cotransporter, NBCe1/Slc4a4, is expressed in subsets of interstitial cells of Cajal (ICCs) responsible for electrical slow wave generation throughout the mouse gastrointestinal tract, while absent in other ICCs. The transcripts of Slc4a4 expressed in mouse ICCs and human gastrointestinal smooth muscle are regulated isoforms. This indicates a significant role for HCO3- transport in the generation of gastrointestinal motility patterns.

Summary: This study focuses on quantifying first-order components of a rift-hosted geothermal field by integrating electromagnetic, lithological, and temperature data through 1D models and a stochastic framework. By jointly modeling a multichannel dataset, key heat flows within a complex magmatic-volcanic-hydrothermal province can be accurately quantified. This approach could be beneficial for decision makers in the geothermal industry to optimize sustainable electricity generation and well drilling locations.
