Soft tissue defects, such as incisional hernia or pelvic organ prolapse, are prevalent pathologies characterized by a tissue microenvironment rich in fragile and dysfunctional fibroblasts. Precision medicine could improve their surgical repair, currently based on polymeric materials. Nonetheless, biomaterial-triggered interventions need first a better understanding of the cell-material interfaces that truly consider the patients' biology.

The depth of myometrial invasion is one of the most important prognostic factors, being directly associated with tumor recurrence and mortality. In this study, ALCAM, a previously described marker of EC recurrence, was studied by immunohistochemistry at the superficial and the invasive tumor areas from 116 EC patients with different degree of myometrial invasion and related to a set of relevant epithelial and mesenchymal markers.

This paper presents the rationale, design, and study protocol for a randomized controlled trial, the aim of which is to evaluate the efficacy and safety of prophylactically placing a bioabsorbable synthetic mesh for reinforcement of a midline fascial closure.
Methods: The PREBIOUS trial (PREventive midline laparotomy closure with a BIOabsorbable mesh) is a multicenter randomized controlled trial in which adult patients undergoing elective or urgent open abdominal operations through a midline laparotomy incision are assigned to one of two groups based on the laparotomy closure procedure: an intervention group in which a continuous polydioxanone (PDS) suture is reinforced with a commercially available GORE® BIO-A® Tissue Reinforcement prosthesis (W.
Background: The malignant potential of tumour cells may be influenced by the molecular nature of KRAS mutations being codon 13 mutations less aggressive than codon 12 ones. Their metabolic profile is also different, with an increased anaerobic glycolytic metabolism in cells harbouring codon 12 KRAS mutations compared with cells containing codon 13 mutations. We hypothesized that this distinct metabolic behaviour could be associated with different HIF-1α expression and a distinct angiogenic profile.

Besides the characteristics of the disorder itself, comorbid disorders play an important role in this complexity. The aim of the study is to analyze the clinical validity of 3 components for BPD Diagnostic and Statistical Manual of Mental Disorders criteria--called affective dysregulation, behavioral dysregulation, and disturbed relatedness--investigating differences in patterns of comorbidity.

The aim of this study was to evaluate the safety and efficacy of prophylactically placing a biodegradable mesh within the incision site at closure in a rat model.
Methods: A 4-cm full-thick midline laparotomy was made in Sprague-Dawley rats along the linea alba and closed by inserting a commercially available web of synthetic polymers (polyglycolic acid-trimethylene carbonate) that are slowly degraded by the body.
We have described recently the Ets family transcription factor, ERM/ETV5, specifically up-regulated in endometrioid endometrial carcinoma (EEC) and associated with myometrial infiltration. Ets family members have been correlated to tumor progression by up-regulating the expression of matrix-degrading proteases. In the present study, we investigated the possibility that in EEC, ERM/ETV5 may act by inducing the expression of genes involved in extracellular matrix remodeling.
