High Levels of Glycosaminoglycans in the Urines of Children with Attention-Deficit/Hyperactivity Disorder (ADHD).

Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral/neurodevelopmental disorder. Some early studies indicated that increased intake of added sugars might have a role in ADHD. In the present study, we tested this possibility by evaluating the urinary excretion of oligosaccharides and glycosaminoglycans (GAGs) in ADHD and control subjects.

Acid glycosaminoglycan (aGAG) excretion is increased in children with autism spectrum disorder, and it can be controlled by diet.

Autism research continues to receive considerable attention as the options for successful management are limited. The understanding of the autism spectrum disorder (ASD) etiology has now progressed to encompass genetic, epigenetic, neurological, hormonal, and environmental factors that affect outcomes for patients with ASD. Glycosaminoglycans (GAGs) are a family of linear, sulfated polysaccharides that are associated with central nervous system (CNS) development, maintenance, and disorders.

[New technique for intestinal lengthening -- from the idea to the clinical application].

Introduction: In severe short bowel syndrome, as a result of the natural adaptation, the bowel becomes overdilated, this interferes with the persitalsis and may lead to stasis, bacterial translocation and sepsis. At present two techniques are used to improve peristalsis. The Bianchi procedure is technically challenging, the Serial Transverse Enteroplasty (STEP) is easy however it results in an aphysiological ultrastructure altering the orientation of the muscle fibres.

High-throughput live-cell imaging reveals differential inhibition of tumor cell proliferation by human fibroblasts.

Increasing evidence indicates that cancer development requires changes both in the precancerous cells and in their microenvironment. To study one aspect of the microenvironmental control, we departed from Michael Stoker's observation (Stroker et al, J Cell Sci 1966;1:297-310) that normal fibroblasts can inhibit the growth of admixed cancer cells (neighbour suppression). We have developed a high-throughput microscopy and image analysis system permitting the examination of live mixed cell cultures growing on 384-well plates, at the single cell level and over time.

[Disease course, frequency of relapses and survival of patients with juvenile or adult dermatomyositis].

Introduction: The idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by chronic muscle inflammation resulting progressive weakness and frequent involvement of internal organs, mainly the pulmonary, gastrointestinal and cardiac systems.

Objective: To present clinical characteristics, disease course, frequency of relapses and survival of 79 patients with juvenile or adult dermatomyositis.

Methods: A national registry of patients with juvenile dermatomyositis was elaborated by the authors in Hungary.
