Background And Objectives: Standard techniques of laparoscopic access involve creating an abdominal wall defect and can result in complications. We describe the umbilical ring easy kannula access (UREKA) technique, evaluating safety and a decrease in complications related to port placement.
Methods: UREKA is performed via a supra- or infraumbilical incision followed by circumferential dissection of the umbilical stalk. The umbilical skin is dissected free from the fascia, exposing the umbilical ring. Pneumoperitoneum is established either before or after placement of a dilating port through the open ring. We reviewed all laparoscopic procedures performed by one pediatric surgeon over 14 months using UREKA.
Results: Ninety-four patients underwent laparoscopic surgery with initial port placement via UREKA. Appendectomy (n=57) was the most common procedure, followed by fundoplication (15) and cholecystectomy (10). No intestinal, solid organ, vascular, or bladder injuries related to port placement occurred. The only postoperative complication was a superficial wound infection in a 135-kg patient following cholecystectomy, treated successfully with oral antibiotics alone.
Conclusion: The umbilical ring persists to some degree in all pediatric patients and provides a safe portal of entry for laparoscopic surgery. UREKA has few complications and is a straightforward, reproducible technique for gaining initial laparoscopic access.

Angiogenesis, a meticulously regulated process essential for both normal development and pathological conditions, necessitates a comprehensive understanding of the endothelial mechanisms governing its progression. Leveraging the zebrafish model and NgAgo knockdown system to identify target genes influencing angiogenesis, our study highlights the significant role of gastric inhibitory polypeptide (GIP) and its receptor (GIPR) in this process. While GIP has been extensively studied for its insulinotropic and glucagonotropic effects, its role in angiogenesis remains unexplored.

A series of Dehydroabietylamine (DHAA) C-ring Schiff derivatives, L-L, were synthesized and their in vitro cytotoxic activity against the human tumor cell lines cervix HeLa, breast MCF-7, lung A549, liver HepG2, and the nonmalignant cell line umbilical vein HUVEC was investigated. Most of the compounds showed varying degrees of anticancer activity against HeLa cell lines while demonstrating lower toxicity to normal HUVEC cells compared to DHAA and doxorubicin (DOX), especially compound L, which not only enhanced the anticancer activity of DHAA, but also significantly reduced the toxicity to normal cells, achieving a selectivity index (SI) 118 times higher than that of DHAA and 245 times higher than that of DOX. In addition, Compound L induced apoptosis in HeLa cells in a dose-dependent manner, suppressed the expression of the anti-apoptotic protein Bcl-2, and arrested the cell cycle at the S phase.

Angiogenesis is mediated by vascular endothelial growth factor (VEGF), a protein that plays a key role in wound healing, inflammatory diseases, cardiovascular processes, ocular diseases, and tumor growth. Indeed, modulation of angiogenesis represents a potential approach to treating cancer and, as such, therapeutic approaches targeting VEGF and its receptors have been widely investigated as part of the broader search for curative interventions. Equally, RNA interference is a powerful tool for treating diseases, but its application as a disease treatment has been limited in part because of a lack of efficient small interfering RNA (siRNA) delivery systems.

Blood vessel formation relies on biochemical and mechanical signals, particularly during sprouting angiogenesis when endothelial tip cells (TCs) guide sprouting through filopodia formation. The contribution of BMP receptors in defining tip-cell characteristics is poorly understood. Our study combines genetic, biochemical, and molecular methods together with 3D traction force microscopy, which reveals an essential role of BMPR2 for actin-driven filopodia formation and mechanical properties of endothelial cells (ECs).

Background: Colorectal cancer (CRC) is the second-leading cause of cancer-related deaths. Curcumin has been reported to have suppressive effects in CRC and to address the physiological limitations of curcumin, a chemically synthesized curcuminoid analog, known as (2E,6E)-2,6-Bis (2,3-Dimethoxy benzylidine) cyclohexanone (DMCH), was developed and the anti-metastatic and anti-angiogenic properties of DMCH in colorectal cell line, SW620 were examined.
Methods: The anti-metastatic effects of DMCH were examined in the SW620 cell line by scratch assay, migration, and invasion assay, while for anti-angiogenesis properties of the cells, the mouse aortic ring assay and Human Umbilical Vein Endothelial Cells (HUVEC) assay were conducted.
