    <p>Abstract</p> <p>Background</p> <p>Vitamin/mineral supplements are among the most commonly used treatments for autism, but the research on their use for treating autism has been limited.</p> <p>Method</p> <p>This study is a randomized, double-blind, placebo-controlled three month vitamin/mineral treatment study. The study involved 141 children and adults with autism, and pre and post symptoms of autism were assessed. None of the participants had taken a vitamin/mineral supplement in the two months prior to the start of the study. For a subset of the participants (53 children ages 5-16) pre and post measurements of nutritional and metabolic status were also conducted.</p> <p>Results</p> <p>The vitamin/mineral supplement was generally well-tolerated, and individually titrated to optimum benefit. Levels of many vitamins, minerals, and biomarkers improved/increased showing good compliance and absorption. Statistically significant improvements in metabolic status were many including: total sulfate (+17%, p = 0.001), S-adenosylmethionine (SAM; +6%, p = 0.003), reduced glutathione (+17%, p = 0.0008), ratio of oxidized glutathione to reduced glutathione (GSSG:GSH; -27%, p = 0.002), nitrotyrosine (-29%, p = 0.004), ATP (+25%, p = 0.000001), NADH (+28%, p = 0.0002), and NADPH (+30%, p = 0.001). Most of these metabolic biomarkers improved to normal or near-normal levels.</p> <p>The supplement group had significantly greater improvements than the placebo group on the Parental Global Impressions-Revised (PGI-R, Average Change, p = 0.008), and on the subscores for Hyperactivity (p = 0.003), Tantrumming (p = 0.009), Overall (p = 0.02), and Receptive Language (p = 0.03). For the other three assessment tools the difference between treatment group and placebo group was not statistically significant.</p> <p>Regression analysis revealed that the degree of improvement on the Average Change of the PGI-R was strongly associated with several biomarkers (adj. R<sup>2 </sup>= 0.61, p < 0.0005) with the initial levels of biotin and vitamin K being the most significant (p < 0.05); both biotin and vitamin K are made by beneficial intestinal flora.</p> <p>Conclusions</p> <p>Oral vitamin/mineral supplementation is beneficial in improving the nutritional and metabolic status of children with autism, including improvements in methylation, glutathione, oxidative stress, sulfation, ATP, NADH, and NADPH. The supplement group had significantly greater improvements than did the placebo group on the PGI-R Average Change. This suggests that a vitamin/mineral supplement is a reasonable adjunct therapy to consider for most children and adults with autism.</p> <p>Trial Registration</p> <p><b>Clinical Trial Registration Number: </b><a href="http://www.clinicaltrials.gov/ct2/show/NCT01225198">NCT01225198</a></p

    Muscle Interstitial Cells: A Brief Field Guide to Non-satellite Cell Populations in Skeletal Muscle

    Skeletal muscle regeneration is mainly enabled by a population of adult stem cells known as satellite cells. Satellite cells have been shown to be indispensable for adult skeletal muscle repair and regeneration. In the last two decades, other stem/progenitor cell populations resident in the skeletal muscle interstitium have been identified as "collaborators" of satellite cells during regeneration. They also appear to have a key role in replacing skeletal muscle with adipose, fibrous, or bone tissue in pathological conditions. Here, we review the role and known functions of these different interstitial skeletal muscle cell types and discuss their role in skeletal muscle tissue homeostasis, regeneration, and disease, including their therapeutic potential for cell transplantation protocols

    Tumour necrosis factor beta gene polymorphisms in myasthenia gravis

    Genetic analyses indicate that genes within the major histocompatibility complex (MHC) can be involved in susceptibility to autoimmune disease. To investigate the role of the tumour necrosis factor beta (TNFB) gene in myasthenia gravis (MG) susceptibility, we analysed an NcoI polymorphism within the TNFB gene in 63 MG patients and 93 healthy individuals. When patients were subdivided according to thymic pathology, we found differences between MG patients with thymic hyperplasia and thymoma versus controls. In MG patients with thymic hyperplasia we found a positive association with the TNFB*1 allele [Relative risk (RR): 2.6; P < 0.001] and phenotype (RR: 1.8; P < 0.005) and a negative association with the TNFB*2/2 genotype (RR: 0.2; P < 0.001) when compared to the controls. On the other hand, in MG patients with thymoma we found a positive association with the TNFB*2/2 genotype (RR: 5.6; P < 0.01) and a negative association with the TNFB*1 allele (RR: 0.3; P < 0.05) and *1/2 genotype (RR: 0.2; P < 0.01). These data suggest that the two different forms of MG can have different pathogenesis and that the TNFB gene could influence susceptibility to MG

    Multi-proxy analysis in defining sedimentary processes in very recent prodelta deposits: the Northern Phlegraean offshoreexample (Eastern Tyrrhenian Margin)

    A multi-proxy analysis of Volturno River prodelta deposits in the outer shelf of Northern Phlegraean margin (Eastern Tyrrhenian Sea) has been carried out to reconstruct the sedimentary processes acting during recent times. The late Holocene sediments were characterized through Subbottom Chirp profiles coupled with sedimentological and petrophysical data. The chronostratigraphic framework was achieved by means of colorimetric parameter a* correlations with nearby dated marine sediment. A time interpretation of about 2,300 years BP is estimated for the sedimentary record collected in the cores. Seismic stratigraphic analysis shows late Holocene outer shelf deposits, characterized by fluid escape features and small-offset faults. However, the undisturbed sedimentation and the preservation of an internal geometry at decimetre scale, as detected by the sedimentological and petrophysical analysis, indicates a slow sliding without sediment reworking for this sedimentological body. So far a possible recent (\2,300 years BP) shear dominated downward displacement of high water content sediments, triggered by the occurrence of seismic activity, is inferred. Based on the depth-age conversion of the detected lithological features, a regular climatically driven change in the sediment supply of the prodelta depositional environment is suggested. The detection of spectrophotometry correlations of Holocene shelf margin sediments, several km apart, goes beyond the previous work and confirms even for continental shelf area the potential value of spectrophotometer data in high-resolution stratigraphic correlations
