Objective: To evaluate the effect of infliximab on adhesion formation and it's associated morbidity and complications.
Methods: This study was performed in the Faculty of Medicine, Gazi University, Turkey between July 2005 and October 2005. Thirty-five rats were randomly divided into 4 groups. Laparotomy was performed in the Sham group (n=5), whereas cecal abrasion was carried out in all other groups. After cecal abrasion 0.9% sodium chloride was administered in the saline group (n=10), infliximab was administered to the study group (n=10) and nothing was administered to the last group (n=10). Adhesion formation was evaluated with macroscopic and microscopic adhesion scoring systems. Peritoneal fluid samples and mesenteric lymph node biopsies were taken to rule out bacterial peritonitis. Blood and peritoneal irrigation fluid samples were taken to measure the Tumor necrosis factor-alpha (TNF-alpha) levels.
Results: Macroscopic adhesion scores showed fewer adhesions in the infliximab group. The infliximab group had significantly fewer adhesions than the abrasion control and saline groups. According to the histological findings, there were no statistically significant differences between the groups.
Conclusion: Early blocking of the activity of TNF-alpha after cecal abrasion resulted in lower rates of adhesion formation, macroscopically. The TNF-alpha, a proinflammatory cytokine appears to be an important mediator for postoperative adhesion formation.

Once multicellularity was thriving, a key development involved the emergence of epithelial layers that separated "inside" from "outside". Most epithelia then generate their own transepithelial electrical signals. So electrical forces were instrumental in the development of epithelial tissues, which themselves generate further electrical signals.

Hydroxyapatite nanoparticles (HANPs) have been applied in several biomedical fields. However, its interaction with biological systems is less exploited. This study aimed to characterize HANPs, examine their influence on kidneys, and explore the potential protective effects of naturally extracted red pigment (RP) from Monascus purpureus against HANPs-induced renal toxicity.

Background: Thrombocytopenia affects 12-20% of women with preeclampsia and a low platelet count impairs coagulation. Women with preeclampsia have an increased risk of both cerebral hemorrhage, thromboembolism, and postpartum hemorrhage. Studies of platelet function and coagulation in women with preeclampsia show conflicting results.

Neurovascular flow-diverting stents (FDSs) are revolutionizing the paradigm for treatment of intracranial aneurysms, but they still face great challenges like post- implantation acute thrombosis and delayed reendothelialization. Surface modification is of crucial relevance in addressing such key issues. In this study, we fabricated an ultrathin nanocoating out of copper (II) together with protocatechuic acid (PCA) and nattokinase (NK) bioactive molecules on NiTi FDSs via a coordination chemistry approach, with favorable biophysiochemical interactions, to fulfill this goal.

Endometriosis is a chronic gynecological disease that affects 1 in 10 reproductive-aged women. Most studies investigate established disease; however, the initiation and early events in endometriotic lesion development remain poorly understood. Our study used neutrophils from human menstrual effluent from subjects with and without endometriosis for immunophenotyping, and a mouse model of endometriosis and a mouse endometriosis cell line to determine the role of neutrophils in the initiating events of endometriosis, including attachment and survival of minced endometrial pieces.
