CD9-positive Exosomes Derived from Cancer-associated Fibroblasts Might Inhibit the Proliferation of Malignant Melanoma Cells.

Background/aim: Exosomes secreted by various cells in the tumour microenvironment have been reported to be mediators of intercellular communication that play an important role in cancer progression. In this study, we aimed to investigate the effects of exosomes derived from cancer-associated fibroblasts (CAFs) on the proliferation of malignant melanoma (MM) cells and evaluated their clinicopathological significance.

Materials And Methods: Three malignant melanoma cell lines, A375, MMAc, and COLO679, and three CAFs established from malignant melanomas at stages 1a, 2b, and 3b, were used.

Venous Flap Reconstruction following Wide Local Excision for Primary Cutaneous Malignancies in Extremities.

Unlabelled: Cutaneous malignancies in the extremities are relatively common, and radical treatment such as ray amputation was performed for certain advanced skin cancer cases in the past. The concept of surgical treatment of primary cutaneous malignant tumor has gradually changed, and preservation of the extremity by performing the appropriate excision and reconstruction became possible. Various reconstructive methods after the resection of malignant tumors such as skin grafts, local flaps, and free flaps, including perforator flaps have been noted.

A Dynamic Costal Cartilage Platform Promotes Ocular Prosthetic Excursion: Preliminary Report.

Unlabelled: The quality of life of the face involves mainly its configuration, and it plays an important functional role in communication skills. Thus, having artificial eyes is extremely essential in maintaining the quality of life of patients who have lost their eyeballs. We will present the details of the technique, including tips and innovations for eye socket reconstruction using spherical costal cartilage implant, which leads to dynamic and aesthetic results.

Combined Method with Free Omentum Flap and Split-thickness Skin Flap for Hand Reconstruction Following Radical Excision of an Arteriovenous Malformation.

The treatment for arterial venous malformation (AVM) of functionally and aesthetically important parts such as the hand is considered to be challenging. AVM existed in the right forearm and the thenar region of 55-year-old man. Combined method with free omentum flap and split-thickness skin flap was performed for hand reconstruction after radical excision of an AVM.

C-X-C Motif Ligand 1 (CXCL1) from melanoma cells down-regulates the invasion of their metastatic melanoma cells.

The surgical resection of a primary melanoma is sometimes followed by the immediate development of distant metastases, suggesting that the primary melanoma might control the metastatic process. We hypothesized that a paracrine factor(s) from primary melanoma cells might regulate the progression of metastasizing melanoma cells. Here we attempted to identify the factor(s) from primary melanoma cells that regulate the invasion ability of metastatic melanoma cells.

The Influence of Palatoplasty on Eating Function.

Postoperative dietary control and surgical procedures are important for minimizing complications after a palatoplasty because the palate is always exposed to stresses by various movements associated with eating. Currently, we provide fluid foods (food paste, liquid food, and soft food) to postpalatoplasty patients. However, nutritional inadequacies associated with fluid food necessitate the need to develop a new food specifically for postpalatoplasty patients.
