8 days (VAC). All grade surgery-related complications were seen in 74% patients (CONV) vs. 74% patients (VAC); grade 3 complications in 3 patients (CONV) vs. 6 patients (VAC). Prolonged hospital stay occurred in 32% patients (CONV) vs. 48% patients (VAC); median hospital stay was 11.5 days. Reintervention due to complications occurred in 45% patients (CONV) vs. 42% patients (VAC). CONCLUSIONS In this prospective, randomized trial we could not observe a significant difference between epidermal vacuum treatment and conventional wound care.Traumatic brain injury (TBI) is a major public health problem worldwide that is associated with increased mortality and morbidity. Posttraumatic epilepsy (PTE) is one of the sequelae of TBI. The aim of this study was to investigate the role of N-acetylcysteine (NAC) as an adjuvant on the efficacy of levetiracetam (LEV) and gabapentin (GBP) in PTE model encouraged by pentylenetetrazol (PTZ) after mild-TBI in male Sprague-Dawley rats. Mild-TBI was performed by the weight-drop method in male Sprague-Dawley rats. PTE model was developed by injecting PTZ (30+15+15 mg/kg, 30 min intervals, i.p.) 7 days after head trauma. After the development of posttraumatic seizures, the rats were treated with NAC (100 mg/kg), LEV (50 mg/kg), GBP (100 mg/kg), NAC+LEV and NAC+GBP intraperitoneally for 14 days. Seizures related to PTE were scored by video-EEG recording. Motor performance of the animals was also evaluated in the rotarod test. 50 mg/kg LEV and 100 mg/kg GBP reduced seizures related to PTE. LEV alone (p = 0.009), but the administration of GBP+NAC (p = 0.015) was more effective on PTE-related seizure control. However, GBP+NAC application adversely affected the fall latency in the rotarod test. In terms of trauma-related seizure control, there was no statistically significant difference between the use of prophylactic LEV and symptomatic LEV. LEV alone or the combination of GBP with NAC provides more effective seizure control in the PTE facilitated by PTZ. On the other hand, the use of prophylactic LEV did not have any extra effect on posttraumatic seizure development and control.BACKGROUND Genomic instability is a hallmark of cancer. Cancer progression depends on the development and amplification of mutations that alter the cellular response to threats to the genome. This can lead to DNA replication stress and the potential loss of genetic integrity of the newly formed cells. This study utilised fission yeast to map the interactions occurring in some of the most crucial pathways in both DNA replication and checkpoint monitoring involving Rad4, the Schizosaccharomyces pombe (S. pombe) TopBP1 homologue. We have modelled conditions of replication stress in the genetically tractable fission yeast, S. pombe using the hypomorphic rad4-116 allele. Synthetic genetic analysis was used to identify processes required for cell survival under conditions of DNA replication stress. XL177A With the aim of mapping the genetic interactions of rad4 and its mutant allele, rad4-116, several genes that could have an interaction with rad4 during replication stress have emerged as attractive. RESULTS Interactions with genes involved in chromatin remodelling, such as hip1, and replication fork stalling resolution, such as mrc1, swi1 and swi3 were explored and confirmed. The interactions of Rad4 with each of the genes provided separate and distinct tumour formation pathways, as evident in the synthetically lethal interactions. Even within the same complex, rad4-116 double mutants behaved differently proving that Rad4 interacts at different levels and functions with the same proteins. CONCLUSION Results from this study provide a novel view of the rad4 interactions, the association of Rad4 with the replisome. The study also provides the groundwork on a theoretical and practical level for the exploration and separation of interactions of TopBP1 with the histone chaperone family and the replisome.BACKGROUND Octamer-binding transcription factor 4 (Oct4) is a transcription factor that has an important role in stem cell differentiation and self-renewal. Oct4 has also been implicated in tumorigenicity of different cancers. This study aimed to analyze Oct4 expression in gastric carcinoma (GC) and to evaluate the relation between Oct4 expression and clinicopathologic parameters, tumor proliferation, and angiogenesis in addition to patient survival. RESULTS Oct4 mRNA was detected by quantitative reverse transcription PCR (qRT-PCR) in 45 GC specimens and adjacent non-cancerous tissues. We found a significant difference in Oct4 mRNA relative expression levels in GC tissue compared with adjacent non-cancerous tissues (p  less then  0.001). Furthermore, immunohistochemistry (IHC) was performed to study the Oct4 expression in GC cases. High Oct4 immunostaining was detected in 62.2% of GC specimens. High Oct4 expression both by mRNA relative quantitation and IHC were significantly related to poorly differentiated tumors, nodal metastasis, and stage III tumors. Moreover, high Oct4 IHC expression was also associated with cases positive for Ki-67 and VEGF expressions (p  less then  0.001 and 0.021, respectively). Oct4 expression identified by both mRNA relative quantitation and IHC was significantly related (p  less then  0.001). As regards patient survival, high Oct4 expression was significantly related to poor overall survival (OS) and disease-free survival (DFS) (p = 0.029 and 0.031, respectively). CONCLUSION Oct4 plays a valuable role in the progression and prognosis of GC. High Oct4 expression is associated with high tumor grade, nodal metastasis, stage III tumors, and poor OS and DFS. High Oct4 is also significantly associated with Ki-67 and VGEF expression, thus enhancing tumor proliferation and angiogenesis.PURPOSE We aim to compare short-term outcomes of robotic intraperitoneal onlay (rIPOM), transabdominal preperitoneal (rTAPP) and retromuscular (rRM) repair for uncomplicated midline primary ventral hernias (PVH) and determine risk factors associated with postoperative complications. METHODS The three groups were compared in terms of pre-, intra-, and post-operative variables. Postoperative complications were assessed using previously validated classifications. Univariate analyses were conducted to determine which variables influence postoperative complications (up to 90 days), followed by a multivariate regression analysis revealing statistically important risk factors. RESULTS A total of 269 patients who underwent robotic PVH repair patients were grouped as rIPOM (n = 90), rTAPP (n = 108), and rRM (n = 71). rRM repair allowed for the use of larger-sized meshes for larger defects; however, it was associated with higher-grade complications. rTAPP repair resulted in the lowest morbidity and offered the highest mesh-to-defect ratio for smaller-sized hernias.
