AI Article Synopsis
- The study aimed to investigate how serum from specific traditional Chinese herbs affects the contraction of rat colonic smooth muscle cells.
- The researchers isolated the muscle cells and tested their contraction in response to different concentrations of the herbal serum, as well as a control substance (acetylcholine).
- Results showed that the herbal serum caused dose-dependent contractions, but the strongest effects among the different herbal serums were not statistically significant from each other.
Article Abstract
Objective: To study the kinetogenic effects of serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala on the colonic smooth muscle cells of rats.
Methods: Serum containing Chinese materia medicas was made according to standard methods. Smooth muscle cells were isolated from the muscle layers of Wistar rat's colon, referred to modified Bitar's method. The contractile response of colonic smooth muscle cells to serum containing Chinese materia medicas (10%, 50%, 100% concentration) and other medicines (blank and 1 x 10(-3) mol/L acetylcholine) were separately observed. The contractility was presented by the decrease of the cell length between the drug groups and the control.
Results: Serum containing each Chinese materia medica can make dose-dependent contraction at different concentrations (P < 0.05), but the strongest effect of each serum had no significant difference (P > 0.05).
Conclusion: Serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala can make notable contraction on colonic smooth muscle cells in rats.

Uterine fibroids are benign monoclonal neoplasms of the myometrium, representing the most common female pelvic neoplasms globally. Treatments may be invasive, such as hysterectomy and myomectomy, non-invasive, such as medical therapy or focused ultrasound, or minimally invasive, such as transcervical radiofrequency ablation (TFA). To date, more than 12,000 women have been treated worldwide using TFA with the Sonata System.

The prevalence of cardiovascular disease varies with sex, and the impact of intrinsic sex-based differences on vasculature is not well understood. Animal models can provide important insights into some aspects of human biology; however, not all discoveries in animal systems translate well to humans. To explore the impact of chromosomal sex on proteomic phenotypes, we used iPSC-derived vascular smooth muscle cells from healthy donors of both sexes to identify sex-based proteomic differences and their possible effects on cardiovascular pathophysiology.

The octapeptide angiotensin II (Ang II) is a circulating hormone as well as a locally formed agonist synthesized by the angiotensin-converting enzyme (ACE) of endothelial cells. It forms a powerful mechanism to control the amount and pressure of body fluids. All main effects are directed to save body salt and water and ensure blood pressure under basic conditions and in emergencies.

Photobiomodulation (PBM) therapy, a therapeutic approach utilizing low-level light, has garnered significant attention for its potential to modulate various biological processes. This study aimed at optimizing and investigating the effects of PBM on angiogenesis and mitochondrial metabolic activity. In vitro experiments using human umbilical vein endothelial cells (HUVECs) and vascular smooth muscle cells (VSMCs) were performed to assess PBM's impacts on cell migration, proliferation, endogenous protoporphyrin IX production, mitochondrial membrane potential, Rhodamine 123 fluorescence lifetime, mitochondrial morphology, and oxygen consumption.
