AbsorbaTack™ vs. ProTack™ vs. sutures: a biomechanical analysis of cervical fixation methods for laparoscopic apical fixations in the porcine model

Fortifying the foundation: assessing the role of uterine ligament integrity in uterine prolapse and beyond

BACKGROUND

Pelvic floor stability is influenced by various biomechanical, anatomical, and physiological factors. Understanding these dynamics is crucial for improving the treatment of pelvic organ prolapse (POP) and related conditions.

OBJECTIVE

To analyze the key factors affecting pelvic floor integrity and explore both non-surgical and surgical interventions to enhance stability and treatment outcomes.

METHODS

This review draws from biomechanical research to assess the role of the uterosacral ligament in pelvic support, while also examining the potential of both traditional and emerging therapeutic approaches, including non-surgical interventions like vitamin C supplementation.

RESULTS

- The uterosacral ligament demonstrates superior strength and stiffness, making it essential for structural support of pelvic organs. - Non-surgical interventions, such as vitamin C supplementation, show potential in improving ligament integrity and preventing pelvic floor disorders. - Emerging surgical techniques, including tendon-based procedures and injectable fibrous hydrogel composites, offer promising improvements in outcomes for patients with pelvic organ prolapse. - Additional factors such as muscle strength and neural deficiencies contribute to the complexity of pelvic floor biomechanics, indicating the need for multifaceted treatment approaches.

CONCLUSION

This analysis provides a comprehensive framework for understanding and managing pelvic floor stability by integrating biomechanical, physiological, and anatomical insights. The findings highlight the potential for personalized treatment strategies to improve patient outcomes in pelvic floor disorders.

Potential of the Novel Slot Blot Method with a PVDF Membrane for Protein Identification and Quantification in Kampo Medicines

Kampo is a Japanese traditional medicine modified from traditional Chinese medicine. Kampo medicines contain various traditional crude drugs with unknown compositions due to the presence of low-molecular-weight compounds and proteins. However, the proteins are generally rare and extracted with high-polarity solvents such as water, making their identification and quantification difficult. To develop methods for identifying and quantifying the proteins in Kampo medicines, in the current study we employ previous technology (e.g., column chromatography, electrophoresis, and membrane chromatography), focusing on membrane chromatography with a polyvinylidene difluoride (PVDF) membrane. Moreover, we consider slot blot analysis based on the principle of membrane chromatography, which is beneficial for analyzing the proteins in Kampo medicines as the volume of the samples is not limited. In this article, we assess a novel slot blot method developed in 2017 and using a PVDF membrane and special lysis buffer to quantify advanced glycation end products-modified proteins against other slot blots. We consider our slot blot analysis superior for identifying and quantifying proteins in Kampo medicines compared with other methods as the data obtained with our novel slot blot can be shown with both error bars and the statistically significant difference, and our operation step is simpler than those of other methods.
