BACKGROUND: Anastomotic stricture following colorectal cancer surgery is not a rare complication, but proper management of anastomotic stricture located close to the anal verge is uncertain. This study aimed to investigate risk factors and management strategies for anastomotic stricture after ultralow anterior resection (ULAR). METHODS: We retrospectively reviewed a database of patients with rectal cancer who underwent surgery between January 2007 and June 2015, and included patients with an anastomosis within 4 cm from the anal verge...

Currently no treatments exist for preterm infants with diffuse white matter injury (DWMI) caused by hypoxia. Due to improved care of preterm neonates and increased recognition by advanced imaging techniques, the prevalence of DWMI is increasing. A better understanding of the pathophysiology of DWMI is therefore of critical importance. The integrated stress response (ISR), a conserved eukaryotic response to myriad stressors including hypoxia, may play a role in hypoxia-induced DWMI and may represent a novel target for much needed therapies...

The development of brief instruments is an important area in the clinical and psychological assessment in the past years. Brief instruments reveal many advantages due to their efficiency and shortness for the users. However, the psychometric standards of development and validation were often neglected during the construction of short forms. The current overview presents 6 brief instruments for the assessment of disordered eating and eating disorders in German: Eating Attitudes Test 8 (EAT-8), Eating Disorder Examination-Questionnaire 8 (EDE-Q8) and the child version (ChEDE-Q8), ICD-10-Symptom-Rating subscale eating disorders (ISR-E), SCOFF questionnaire, and Short Evaluation of Eating Disorders (SEED)...

Traumatic brain injury (TBI) is a leading cause of long-term neurological disability, yet the mechanisms underlying the chronic cognitive deficits associated with TBI remain unknown. Consequently, there are no effective treatments for patients suffering from the long-lasting symptoms of TBI. Here, we show that TBI persistently activates the integrated stress response (ISR), a universal intracellular signaling pathway that responds to a variety of cellular conditions and regulates protein translation via phosphorylation of the translation initiation factor eIF2α...

Inverse Stochastic Resonance (ISR) is a phenomenon in which the average spiking rate of a neuron exhibits a minimum with respect to noise. ISR has been studied in individual neurons, but here, we investigate ISR in scale-free networks, where the average spiking rate is calculated over the neuronal population. We use Hodgkin-Huxley model neurons with channel noise (i.e., stochastic gating variable dynamics), and the network connectivity is implemented via electrical or chemical connections (i.e., gap junctions or excitatory/inhibitory synapses)...

BACKGROUND: Traditional immunosuppressive regimens (ISR) used in lung transplantation rely on calcineurin inhibitors (CNI) that occasionally cause severe adverse reactions necessitating discontinuation. Belatacept is a novel costimulation antagonist approved for use in renal transplantation which lacks data in lung transplantation. This series aims to describe the response to belatacept ISR in 11 lung transplantation recipients after CNI failure. METHODS: Single center, retrospective medical record review of adult lung transplant recipients (LTR) before and after conversion to belatacept-based ISR...

Overlapping stents are widely used in vascular stent surgeries. However, the rate of stent fractures (SF) and in-stent restenosis (ISR) after using overlapping stents is higher than that of single stent implantations. Published studies investigating the nature of overlapping stents rely primarily on medical images, which can only reveal the effect of the surgery without providing insights into how stent overlap influences the implantation process. In this paper, a finite element analysis of the overlapping stent implantation process was performed to study the interaction between overlapping stents...

Interictal spikes (IS) are one of the major hallmarks of epilepsy. Understanding the factors promoting or suppressing IS would increase our comprehension of epilepsy and possibly open new avenues for therapy. Sleep strongly influences epileptic activity, and the modulatory effects of the different sleep stages on IS have been studied for decades. However, several aspects are still disputed, in particular the role of sleep spindles and slow waves in the activation of IS during Non-REM sleep. Here, we correlate the rate of IS with quantitative measures derived from stereo-EEG during one Non-REM cycle in 10 patients suffering from drug-resistant epilepsy due to type 2 focal cortical dysplasia...

PURPOSE: To investigate whether administering cilostazol after treatment for femoropopliteal in-stent restenosis (ISR) can have a positive impact on recurrent ISR (Re-ISR). METHODS: The database of a multicenter, retrospective, observational registry was interrogated to identify 338 consecutive patients (mean age 72.3±8.8 years; 148 men) who underwent endovascular therapy for femoropopliteal ISR in 379 limbs from January 2010 to December 2014. Ninety-seven patients (103 limbs) who received cilostazol after the initial stent implantation procedure were excluded...

In-stent restenosis (ISR) is a limitation of percutaneous coronary intervention and has been linked to specific clinical and angiographic variables. The aim of the present study was to investigate the predictive value of preprocedural CHA2DS2-VASc score on ISR in patients undergoing revascularization with bare-metal stent (BMS) implantation for stable coronary artery disease or acute coronary syndrome. In the years 2012 to 2014, a total of 358 consecutive patients (mean age: 62.36 ± 11.28 years and 62.2% men) who had undergone successful BMS implantation were included in the study...

INTRODUCTION: In-stent restenosis (ISR) remains a major limitation of percutaneous coronary intervention (PCI). A role for peripheral blood cells as major regulators of immune and inflammatory systems has been proposed. We aim to evaluate the relationship between eosinophil count and development of restenosis after drug-eluting stent (DES) implantation. METHODS: In this prospective study, all consecutive patients undergoing elective DES implantation for chronic stable angina (CSA) in a university-affiliated heart center within a 6-month period were enrolled and followed for another 6 months...

Root colonization by Trichoderma fungi can trigger induced systemic resistance (ISR). In Arabidopsis, Trichoderma-ISR relies on the transcription factor MYB72, which plays a dual role in the onset of ISR and the activation of Fe uptake responses. Volatile compounds (VCs) from rhizobacteria are important elicitors of MYB72 in Arabidopsis roots. Here we investigated the mode of action of VCs from Trichoderma fungi in the onset of ISR and Fe uptake responses. VCs from Trichoderma asperellum and Trichoderma harzianum were applied in an in vitro split-plate system with Arabidopsis or tomato seedlings...

Multi-organ failure in response to uncontrolled microbial infection is characterized by low blood pressure accompanied by a systemic over-inflammation state, caused by massive pro-inflammatory cytokines release and liver damage. Recently, the integrated stress response (ISR), characterized by eukaryotic translation initiation factor 2α (eIF2α) phosphorylation, was involved with controlling apoptosis in stressed hepatocytes and associated with poor survival to endotoxin challenge. Lipopolysaccharide (LPS) alone is able to induce the ISR in hepatocytes and can trigger massive liver damage along with tumor necrosis factor-alpha (TNF-α) expression...

BACKGROUND: Our study aimed to compare the efficacy of seal-wing paclitaxel-eluting balloon catheters (PEB) with iopromide-coated PEB and everolimus-eluting stents (EES) for treating bare metal stent restenosis (BMS-ISR). METHODS: We enrolled 64 patients with 69 BMS-ISR. The control group comprised patients from the iopromide-PEB and EES arms of a previous TIS study. The primary end-point was 12-month in-segment late lumen loss (LLL). Secondary end-points included incidence of binary in-stent restenosis and 12-month major adverse cardiac events (MACE)...

Functional neuroimaging has been used to show that the developing auditory cortex of very young human infants responds, in some way, to sound. However, impoverished stimuli and uncontrolled designs have made it difficult to attribute brain responses to specific auditory features, and thus made it difficult to assess the maturity of feature tuning in auditory cortex. To address this, we used functional magnetic resonance imaging (fMRI) to measure the brain activity evoked by naturalistic sounds (a series of sung lullabies) in two groups of infants (3 and 9 months) and adults...

Robotic surgical system has been widely applied in sphincter-preserving surgery for low rectal cancer with the advantages of clear 3D images and stably flexile manipulation. Its application principle includes radical resection of tumor and complete preservation of function. The main operation procedures of robotic surgical system in sphincter-preserving surgery for low rectal cancer are as follows: (1) Anterior resection of low rectal cancer: It is safe and feasible and has obvious advantages in observation of pelvic nerves, dissociation of presacral and sacral side, and high rate of sphincter-preserving, while the improvement of postoperative recovery and long-term survival needs to be verified by further large sample researches...

Hydrogen sulfide (H2S) regulates various physiological processes including neuronal activity, vascular tone, inflammation, and energy metabolism. Moreover, H2S elicits cytoprotective effects against stressors in various cellular models of injury. However, the mechanism of the signaling pathways mediating the cytoprotective functions of H2S is not well understood. We previously uncovered a heme-dependent metabolic switch for transient induction of H2S production in the transsulfuration pathway. Here, we demonstrate that increased endogenous H2S production or its exogenous administration modulates major components of the integrated stress response (ISR) promoting a metabolic state primed for stress response...

Cells are exposed to various intrinsic and extrinsic stresses in both physiological and pathological conditions. To adapt to those conditions, cells have evolved various mechanisms to cope with the disturbances in protein demand, largely through the Unfolded Protein Response (UPR) in the Endoplasmic Reticulum (ER), but also through the Integrated Stress Response (ISR). Both responses initiate downstream signaling to transcription factors that, in turn, trigger adaptive programs and/or in the case of prolonged stress, cell death mechanisms...
