Summary: This paper introduces a toolbox called "BigBrainWarp" aimed at simplifying the workflow of integrating histological atlases of the human brain with multi-modal neuroimaging and promoting the adoption of best practices. The toolbox provides a simple wrapper function for users to easily map data between BigBrain and standard MRI spaces, automatically pulling specialized transformation procedures based on a wide collaborative network of researchers to support multi-scale brain organization investigations.

Summary: This study examined the three-dimensional morphological changes of urination and urinary continence anatomical structures in overactive bladder (OAB) patients. The findings showed that OAB patients had increased thickness and volume of the bladder detrusor, as well as lower thickness and volume of the main part of the urethral sphincter. These results provide valuable insights for the diagnosis and treatment of OAB.

Summary: This study found that nearly half of women seeking pelvic floor physical therapy for pelvic pain also had coccygodynia. These women had higher pain scores, increased pelvic floor dysfunction, and significantly greater abnormal physical exam findings. The study highlights the strong link between coccygodynia, pelvic floor symptoms, and pelvic pain.

Summary: In this study, the clinical application of a depithelized gracilis adipofascial flap for pelvic floor reconstruction after pelvic exenteration was evaluated. The flap was found to be an ideal and reliable choice with few complications, a high survival rate, sufficient volume, and minimal impact on the donor site function.

Summary: Dissection of the pelvic floor reveals its elegant simplicity, but confusion arises due to conflicting illustrations and lack of anatomical accuracy. To overcome this, we must focus on structures rather than words, reject theory-induced blindness, and revive century-old standards of anatomical illustration.

Summary: The study aimed to evaluate the feasibility of using New Zealand White rabbits for studying implanted biomaterials in pelvic reconstructive surgery, and to compare the occurrence of graft-related complications between a commercial polypropylene mesh and a newly developed human dermal matrix. Results showed that NZW rabbits are a suitable model for evaluating graft materials, with hADM associated with fewer complications and better tissue integration compared to PP mesh.

Summary: In this study, an efficient automatic segmentation model of pelvic floor muscles with MRI was proposed based on DenseUnet, which achieved muscle volume calculation and provided a reference for assessing pelvic floor function. The improved DenseUnet showed good segmentation performance, time efficiency, and accuracy compared to manual segmentation.

Summary: The plate-like structure, known as the pancreas-major arteries ligament, is located behind the portal vein system, between the pancreatic head and the celiac trunk and superior mesenteric artery. It consists of fibrous bundles connected to major arteries and the pancreas, providing a comprehensive understanding of the anatomy surrounding the pancreatic head.

Summary: Recent studies have revealed extended smooth muscle structures in the male pelvic floor, including the anterior longitudinal muscle bundle, bilateral plate-like structures, and the rectourethral muscle. These structures have varying fiber orientations and densities, suggesting a dynamic coordination mechanism between smooth and skeletal muscles in the pelvic floor.

Summary: This study analyzed the anatomical basis of force transmission between the hip muscle obturator internus and the pelvic floor muscle levator ani. The results showed that these muscles were in broad contact through the obturator fascia, and the obturator fascia provided attachment for the levator ani. This anatomical feature suggests that hip muscle movement contributes to pelvic floor support and improves defaecation/urinary function.

Summary: The purpose of this review is to discuss our research on the pelvic outlet muscles and provide insights into the mechanism of pelvic floor stabilization. The study incorporates macroscopic examination, immunohistological analysis, 3D reconstruction, and imaging techniques. It goes beyond previous reports by including both skeletal and smooth muscle structures in the pelvic floor and perineum. The findings suggest new concepts of pelvic floor stabilization, such as dynamic coordination between skeletal and smooth muscles.

Summary: This study aimed to characterize the anatomical configuration of the deep brachial artery and evaluate its clinical utility as a recipient artery in free-flap transfers for reconstruction of the posterior upper arm. The deep brachial artery was found between the long head and lateral head of the triceps brachii muscle, crossing the x-axis at an average distance of 13.2±2.9 cm from the acromion, with an average diameter of 1.9±0.49 mm. In clinical cases, the superficial circumflex iliac perforator flap was used for coverage, with the deep brachial artery as the recipient artery. All flaps survived completely with no complications.
