Literature review comparing laparoscopic and percutaneous endoscopic gastrostomies in a pediatric population.

Objective. This study compares laparoscopic and percutaneous endoscopic gastrostomy (PEG) in a paediatric population to test the hypothesis that there is a difference in the frequency of serious gastrointestinal complications between the two methods. Methods. All reports published between 1995 and 2009 on laparoscopic gastrostomy and PEG in children was included. Prospective and retrospective tria

Can microRNAs control vascular smooth muscle phenotypic modulation and the response to injury?

Vascular smooth muscle cell (VSMC) migration and proliferation are critical events in vascular proliferative diseases. Recent studies have established micro-RNAs (miRNAs) as important mediators for the modulation of VSMC phenotype by targeting transcription factors and the cytoskeleton, which act as molecular switches for VSMC differentiation. The importance of miRNAs for VSMC development, differe

Estimated clinical benefit of protecting neurogenesis in the developing brain during radiation therapy for pediatric medulloblastoma.

We sought to assess the feasibility and estimate the benefit of sparing the neurogenic niches when irradiating the brain of pediatric patients with medulloblastoma (MB) based on clinical outcome data. Pediatric MB survivors experience a high risk of neurocognitive adverse effects, often attributed to the whole-brain irradiation that is part of standard management. Neurogenesis is very sensitive to

Helicobacter species and gut bacterial DNA in Meckel's diverticulum and the appendix.

AIM: To analyse the possible association of various Helicobacter species and certain common gut bacteria in patients with Meckel's diverticulum and appendicitis. METHODS: A nested-polymerase chain reaction (PCR), specific to 16S rRNA of the Helicobacter genus, was performed on paraffin embedded samples, 50 with acute appendicitis, 50 normal appendixes, and 33 Meckel's diverticulum with gastric he

Myocardium at risk can be determined by ex vivo T2-weighted magnetic resonance imaging even in the presence of gadolinium: comparison to myocardial perfusion single photon emission computed tomography.

AIMS: Determination of the myocardium at risk (MaR) and final infarct size by cardiac magnetic resonance imaging (CMR) enables calculation of salvaged myocardium in acute infarction. T2-weighted imaging is performed prior to the administration of gadolinium, since gadolinium affects T2 tissue properties. This is, however, difficult in an ex vivo model since gadolinium must be administered for dete

Human neural progenitor cells promote photoreceptor survival in retinal explants.

Different types of progenitor and stem cells have been shown to provide neuroprotection in animal models of photoreceptor degeneration. The present study was conducted to investigate whether human neural progenitor cells (HNPCs) have neuroprotective properties on retinal explants models with calpain- and caspase-3-dependent photoreceptor cell death. In the first experiments, HNPCs in a feeder laye

Exercise-induced release of cytokines in patients with major depressive disorder.

BACKGROUND: Patients with major depressive disorder (MDD) may display elevated plasma levels of pro-inflammatory substances. Although the underlying mechanisms are unknown, inflammation has been proposed to play a direct role in the generation of depressive symptoms. Skeletal muscle is a potent producer of cytokines, and physical exercise has been suggested to alleviate symptoms of depression. In

Structural and Functional Progression in the Early Manifest Glaucoma Trial.

PurposeTo elucidate the temporal relationship between detection of glaucomatous optic disc progression, as assessed by fundus photography, and visual field progression.DesignProspective, randomized, longitudinal trial.ParticipantsThree hundred six study eyes with manifest glaucoma with field loss and 192 fellow eyes without any field defect at the start of the trial, from a total of 249 subjects i

Light vs. heavy sedation during mechanical ventilation after oesophagectomy--a pilot experimental study focusing on memory.

BACKGROUND: To assess and compare the feasibility and stressful memories of light vs. heavy sedation during post-operative mechanical ventilation. METHODS: Randomized clinical trial in one general intensive care unit (ICU) in a Swedish university hospital. Thirty-six adults were randomly assigned to receive either light [Motor Activity Assessment Scale (MAAS) 3-4] or heavy (MAAS 1-2) sedation with

Human aggrecanase generated synovial fluid fragment levels are elevated directly after knee injuries due to proteolysis both in the inter globular and chondroitin sulfate domains.

OBJECTIVE: To examine different aggrecanase generated fragments in synovial fluid (SF) from patients with acute and chronic knee injuries and from knee healthy subjects. METHODS: We prepared SF-D1 samples from acute (n=35) and chronic (n=35) knee injury patients and knee healthy subjects (n=10). Aggrecan fragments were analyzed in the SF-D1 samples by quantitative (G1, ARGS, KEEE and G3 antibodies

Long-term Outcome After Surgical Treatment of Lipedema.

Lipedema is a condition characterized by abnormal deposition of adipose tissue in the lower extremities leading to circumferential bilateral lower extremity enlargement typically seen extending from the hips to the ankles. Diagnosis of the condition is often challenging, and patients frequently undergo a variety of unsuccessful therapies before receiving the proper diagnosis and appropriate manage

Probiotics lower plasma glucose in the high-fat fed C57BL/6J mouse.

Today, the gut microbiota is considered a key organ in host nutritional metabolism and recent data have suggested that alterations in gut microbiota contribute to the development of type 2 diabetes and obesity. Accordingly, a whole range of beneficial effects relating to inflammation and gut health have been observed following administration of probiotics to both humans and different animal models

Early changes in the hypothalamic region in prodromal Huntington disease revealed by MRI analysis.

Huntington disease (HD) is a fatal neurodegenerative disorder caused by an expanded CAG repeat. Its length can be used to estimate the time of clinical diagnosis, which is defined by overt motor symptoms. Non-motor symptoms begin before motor onset, and involve changes in hypothalamus-regulated functions such as sleep, emotion and metabolism. Therefore we hypothesized that hypothalamic changes occ

Depoliticising water conflict. The quest for functional peacebuilding in the Red Sea-Dead-Sea-Water-Conveyance project.

This article analyses the nexus of technocracy-peacebuilding and its implications on water conflicts and hydropolitics. It is a conceptual exploration, which advances an interdisciplinary approach by combining theories from two distinct research fields: peacebuilding and transboundary water management. It probes the argument that synergies between water management, development and peacebuilding fr

Inhibition of mitogen-activated protein kinase 1/2 in the acute phase of stroke improves long-term neurological outcome and promotes recovery processes in rats.

Extracellular signal-regulated kinase (ERK) 1/2 is activated during acute phase of stroke and contributes to stroke pathology. We have found that acute treatment with MEK1/2 inhibitors decrease infarct size and neurological deficits two days after experimental stroke. However it is not known whether benefits of this inhibition persist long-term. Therefore, the aim of this study was to assess neuro

Multiple Constraints Driven System-on-Chip Test Time Optimization

The cost oftesting SOCs (systems-on-chip) is highly related to the testapplication time. The problem is that the test application timeincreases as the technology makes it possible to design highlycomplex chips. These complex chips include a high number of faultsites, which need a high test data volume for testing, and the hightest data volume leads to long test application times. For modularcore-b
