BACKGROUND: Hepatic steatosis causes severe liver damage and has deleterious effects when associated with ischemia-reperfusion mechanisms. Ischemic preconditioning (IPC) protects lean liver against prolonged ischemia by improving micro-circulation and reducing lipid peroxidation. We investigated the effect of intermittent IPC on liver ischemia-reperfusion injury (IRI) and extensive hepatectomy in severe hepatic steatosis. METHODS: Severe hepatic steatosis was performed by 12-14 weeks of choline-free diet in 108 Wistar rats...

BACKGROUND: The frequency of laparoscopic approaches increased in hernia surgery over the past years. After mesh placement in IPOM position, the real extent of the meshes configurational changes after termination of pneumoperitoneum is still largely unknown. To prevent a later mesh folding it might be useful to place the mesh while it is kept under tension. Conventionally used meshes may lose their Effective Porosity under these conditions due to poor elastic properties. The aim of this study was to evaluate a newly developed elastic thermoplastic polyurethane (TPU) containing mesh that retains its Effective Porosity under mechanical strain in IPOM position in a porcine model...

Malabsorption is a major and common clinical characteristics of short bowel syndrome (SBS) and inflammatory bowel diseases (IBD). Traditional treatment opportunities have focused on decreasing malabsorptive losses via dietary modifications and antisecretory/antidiarrheal agents. However, novel therapeutic modalities aim to enhance the absorptive capacity of the residual bowel by the administration of different intestinal growth factors including teduglutide. In a current study the existence of two distinct functional putative epithelial stem cell subpopulations (i...

Back pain is a major health problem. The degenerative cascade of the spine begins in the intervertebral disc, due to an impairment in the blood supply through the vertebral endplates. Our objective was to develop a novel disc degeneration model based on these premises, akin to the process in humans, in contrast to other proposed models (puncture, enzyme injection, aberrant loads,…) Material and methods: 37 Sprague-Dawley rats, 2 arms: (a) histological (n = 17, one died), en- bloc sections, Van Gieson staining, (Nisimura-Mochida criteria) and also collagen VI staining (tissue oxidative stress), four animals were euthanized every 2 weeks (2-8); and (b) imaging (n = 20, six wound sloughs), MRI 9...

PURPOSE: Endometriosis is a disease that affects 6-10% of the female population, mainly women of reproductive age, and causes a variety of cyclic symptoms. Deep infiltrating endometriosis and in particular bowel involvement presents a challenge for modern surgery. To date, there are no experimental animal models in this field, demonstrating experimental induction of endometriosis directly attached to surface of the colon imitating human colorectal endometriosis; hence, the implementation of novel pharmaceutical and surgical strategies for the management of colorectal endometriosis is mainly limited to clinical studies...

PURPOSE: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation. MATERIALS AND METHODS: We selected 112 patients who underwent nonrigid fixation (17 men and 44 women) or posterior lumbar interbody fusion (13 men and 38 women) for this retrospective study. Based on the T2-weighted magnetic resonance imaging (MRI) scans taken preoperatively, and 6, 12, and 24 months after surgery, the nucleus pulposus in the upper segments of the operated level was considered an ellipsoid, and their volumes were measured respectively and then compared between the two groups...

INTRODUCTION: Liposuction is a popular surgical procedure. As in any surgery, there are risks and complications, especially when combined with fat injection. Case reports of fat embolism have described a possible explanation as the puncture and tear of gluteal vessels during the procedure, especially when a deep injection is planned. METHODS: A total of 10 dissections were performed in five fresh cadavers. Each buttocks was divided into four quadrants. We focused on the location where the gluteal vessels enter the muscle and the diameter of the vessels...

PURPOSE: Despite a substantial amount of literature on tissue-guided regeneration, decellularization process, repopulation time points and stem cell turnover, more in-depth study on the argument is required. Currently, there are plenty of reports involving large animals, as well as clinical studies facing cardiac repair with decellularized homografts, but no exhaustive rodent models are described. The purpose of this study was to develop such a model in rats; preliminary results are also herein reported...
