Show Abstract
Hide Abstract
Implantation of a magnetic lower esophageal sphincter augmentation device is now an alternative to fundoplication in the surgical management of gastroesophageal reflux disease (GERD). Although successful management of GERD has been reported following placement of the device, there are instances when device removal is needed. The details of the technique for laparoscopic magnetic lower esophageal sphincter device removal are presented to assist surgeons should device removal become necessary.

Foramen of Winslow hernia: a minimally invasive approach.
Surg Endosc
PUBLISHED: 07-11-2014
Show Abstract
Hide Abstract
Hernias through the foramen of Winslow comprise 8 % of all internal hernias and the majority contain incarcerated bowel. Clinical signs are often non-specific and delay in diagnosis associated with a mortality rate that approaches 50 %. Management is urgent surgical reduction with bowel decompression and resection of devitalized bowel. A foramen of Winslow hernia (FWH) has traditionally been managed via an exploratory laparotomy incision and the vast majority of cases describe an open approach. We describe a minimally invasive approach to the management of an incarcerated FWH requiring decompression and bowel resection.

[Current concepts of weaning children from invasive ventilation].
Anasthesiol Intensivmed Notfallmed Schmerzther
PUBLISHED: 11-05-2013
Show Abstract
Hide Abstract
Timely weaning from invasive ventilation is of major importance to limit time of invasive ventilation and improve outcomes. However, in pediatrics only limited knowledge on the optimal weaning approach is available. In this review evidence from recent trials on weaning in pediatrics is summarized. Standardized daily evaluation of weaning readiness, daily interruption of sedation, use of pediatric sedation protocols, application of noninvasive ventilation and prophylactic treatment with steroids of patients with high risk for post-extubation upper airway obstruction have been shown to decrease duration of invasive ventilation or to decrease the risk of extubation failure. However, due to the heterogeneous patient population in pediatric intensive care units, an individual approach might be necessary for certain subgroups of pediatric patients.

Cerebral oxygenation in very low birth weight infants supported with sustained lung inflations after birth.
Pediatr. Res.
PUBLISHED: 04-28-2011
Show Abstract
Hide Abstract
Sustained lung inflations (SIs) immediately after birth might decrease the need for subsequent mechanical ventilation in preterm infants. However, effects of SIs on oxygenation and hemodynamics are undetermined. Our aim was to study immediate effects of SIs on heart rate, arterial oxygen saturation, and cerebral tissue oxygen saturation in preterm infants supported with SIs after birth for lung recruitment. Heart rate, arterial oxygen saturation, and cerebral tissue oxygen saturation using near infrared spectroscopy was measured in 24 preterm infants of 28.0 (26.6-29.3) wk GA [median (interquartile range)] during resuscitation using up to three SIs of 20, 25, and 30 cm H2O of 15 s duration each followed by nasal continuous positive airway pressure (CPAP) as first line approach for respiratory support. During positioning and suctioning immediately after delivery infants became progressively hypoxemic and bradycardic before respiratory support was initiated. In 18 infants (75%), more than one SI were applied. During the last SIs, there was a rapid increase in the infants heart rate and an increase in cerebral tissue oxygen saturation. Arterial saturation increased with slight delay. In conclusion, effective last sustained inflations increase heart rate and cerebral tissue oxygen saturation to be followed by an increase in arterial saturation.

Optimization and characterization of a highly-efficient diffraction nanograting for MHz XUV pulses.
Opt Express
PUBLISHED: 03-04-2011
Show Abstract
Hide Abstract
We designed, fabricated and characterized a nano-periodical highly-efficient blazed grating for extreme-ultraviolet (XUV) radiation. The grating was optimized by the rigorous coupled-wave analysis method (RCWA) and milled into the top layer of a highly-reflective mirror for IR light. The XUV diffraction efficiency was determined to be around 20% in the range from 35.5 to 79.2 nm. The effects of the nanograting on the reflectivity of the IR light and non-linear effects introduced by the nanograting have been measured and are discussed.

Investigation on the properties of a laminar grating as a soft x-ray beam splitter.
Appl Opt
PUBLISHED: 08-11-2010
Show Abstract
Hide Abstract
Laminar-type gratings as soft x-ray beam splitters for interferometry are presented. Gold-coated grating beam splitters with 1000 lines/mm are designed for grazing incidence operation at 13.9 nm. They are routinely fabricated using electron beam lithography and ion etching techniques. The laminar grating is measured to have almost equal absolute efficiencies of about 20% in the zeroth and -1st orders, which enables a fringe visibility up to 0.99 in the interferometer. The discrepancy of the grating profiles between the optimized theoretical and the experimental results is analyzed according to the comparison of the optimized simulation results and the measurement realization of the grating efficiencies. By a precise control of the grating profile, the grating efficiency in the -1st order and the fringe visibility could be improved to 25% and 1, respectively.

Residual CD95-pathway function in children with autoimmune lymphoproliferative syndrome is independent from clinical state and genotype of CD95 mutation.
Pediatr. Res.
PUBLISHED: 05-01-2009
Show Abstract
Hide Abstract
Human autoimmune lymphoproliferative syndrome (ALPS) is caused by defective CD95-mediated apoptosis of lymphocytes. In most patients, heterozygous mutations within the CD95 gene are found. Mutated proteins interfere with CD95-signaling in a dominant-negative way. However, the penetrance of clinical disease is variable. We describe 13 patients out of nine families with the clinical presentation of ALPS. Eight different mutations were detected. Sensitivity to CD95-induced cell-death, assembly of the CD95-death-inducing signaling complex (DISC), and activity of initiator caspases-8 and -10 were compared in EBV-transformed B-lymphoblastoid cells of these patients. All CD95-mutations led to a reduced DISC formation and diminished initiator caspase activity upon CD95-stimulation, whereas a marked heterogeneity in sensitivity to CD95-induced killing was found. Residual apoptosis sensitivity to almost normal levels could be achieved upon cross-linking by addition of protein A. Thus, no correlation between residual CD95 sensitivity and clinical phenotype or genotype of ALPS was found. This observation is only partially explained by the variable effects of the CD95-mutations themselves. It also points to a pronounced influence of additional factors, such as modifier pathways or exogenous effects apart from the CD95 pathway in the pathogenesis of ALPS.

Pseudotumor cerebri associated with modified Fontan anatomy.
Pediatr Cardiol
Show Abstract
Hide Abstract
Surgical treatment of functional single-ventricle heart disease with a modified Fontan procedure results in elevated central venous pressure. The case report describes a 19-year-old boy with hypoplastic left heart syndrome and Fontan palliation that resulted in frequent debilitating headaches after transcatheter closure of systemic venous-to-pulmonary venous collaterals. Measured increased intracranial pressure and prompt relief of the headaches with lumbar puncture favored a diagnosis of pseudotumor cerebri. After implantation of a lumboperitoneal shunt, the patients headaches improved dramatically. Headaches are frequent in patients with Fontan circulation. The current literature supports a pivotal role of elevated dural venous sinus pressure in the pathogenesis of pseudotumor cerebri. The high superior and inferior vena caval pressures characteristic of modified Fontan anatomy may account for headaches in some of these patients.

Plasmonic properties of aluminum nanorings generated by double patterning.
Opt Lett
Show Abstract
Hide Abstract
In this Letter we evaluate a technique for the efficient and flexible generation of aluminum nanorings based on double patterning and variable shaped electron beam lithography. The process is demonstrated by realizing nanorings with diameters down to 90 nm and feature sizes of 30 nm utilizing a writing speed of one ring per microsecond. Because of redepositions caused by involved etching processes, the material of the rings and, therefore, the impact on the plasmonic properties, are unknown. This issue, which is commonly encountered when metals are nanostructured, is solved by adapting a realistic simulation model that accounts for geometry details and effective material properties. Based on this model, the redepositions are quantified, the plasmonic properties are investigated, and a design tool for the very general class of nanofabrication techniques involving the etching of metals is provided.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
