For commissioning of a proton therapy unit depth dose distributions must be determined and introduced into the Treatment Planning System. In pencil beam scanning (PBS) technique, integral depth dose (IDD) acquisition should be performed with detector large enough to ensure entire beam laterally broadened by scattered and secondary contributions. The purpose of this article is to quantify, using measurements and Monte Carlo transport calculations, the ionization chamber's (IC) geometrical efficiency versus the chamber radius and proton beam energy...

Intervertebral disc degeneration (IDD) is associated with the deterioration of nucleus pulposus (NP) cells due to hypertrophic differentiation and calcification. Emerging studies have shown that long noncoding RNAs (lncRNAs) play critical roles in the development of IDD. Using bioinformatics prediction, we hereby sought to identify the lncRNAs that regulate the expression of microRNA-146a-5p (miR-146a-5p), an IDD-related inflammatory factor. Our study demonstrated that lncRNA HCG18 acted as an endogenous sponge to down-regulate miR-146a-5p expression in the NP cells by directly binding to miR-146a-5p...

Iodine deficiency in soils and plants is a common problem in the hilly areas and has still been ignored. The aim of the current study is to investigate associated health issues, socio-economic characteristics and people's perception regarding iodine deficiency. Furthermore, a follow-up study was conducted to determine iodine and nutrients concentration in soil and crops at District Diamer, Gilgit-Baltistan, Pakistan. A descriptive and empirical analysis was examined. Most importantly, male was significantly observed as more affected for iodine deficiency than female, as contrary to the literature, socio-economic factors such as households' income and awareness (education) are reported as negative and significant contributor to reduce the iodine deficiency among the people irrespective of the gender...

BACKGROUND: Numerous studies have assessed the socio-cognitive profile in Williams syndrome (WS) and, independently, in 22q11.2 deletion syndrome (22q11.2DS). Yet, a cross-syndrome comparison of these abilities between individuals with these two syndromes with known social deficits has not been conducted. METHODS: Eighty-two children participated in four study groups: WS (n = 18), 22q112.DS (n = 24), age-matched individuals with idiopathic developmental disability (IDD; n = 20) and typically developing (TD) controls (n = 20)...

Circular RNAs (circRNAs) are relatively recently identified noncoding RNAs that are ubiquitously expressed in human tissues and serve key functions in regulating gene expression. However, few studies have focused on human intervertebral disc degeneration (IDD) circRNAs, and the potential role of circRNAs in IDD has not been described in detail. In the present study, circRNA expression data was downloaded from the Gene Expression Omnibus database, and circRNAs in the human intervertebral disc were classified according to their length, indicating their uniform distribution of circRNAs of different lengths...

The importance of supporting families with members who have intellectual and developmental disabilities (IDD) is well-established in both policy and research. Yet little is known about how familiar parents are with existing resources (e.g., programs, supports, trainings), what information they would consider most helpful, and how they would prefer to access resources. Our study examined the resource needs of 1,738 parents of children and adults with IDD in the state of Tennessee. Most parents reported limited familiarity with programs across every domain (e...

Medicaid Home and Community Based Services (HCBS) 1915(c) waivers are the largest source of funding for the long term services and supports of people with intellectual and developmental disabilities (IDD). National-level analyses of HCBS IDD waivers are crucial because of the large variance across states, the recent CMS rule and regulation changes (CMS 2249-F/2296-F), and the ever changing economic and political landscape. Therefore, the aim of this study was to examine state waiver priorities for people with IDD...

This grounded theory study gathered descriptions the bereavement experience for adults with intellectual disabilities (IDD) through the eyes and voices of a small sample of grief counselors. The counselors described bereaved adults with IDD as individuals who faced potentially heightened effects of the broken attachment bonds, increased risk of coping obstacles, long histories of unrecognized losses, and disenfranchised grief. The participants described bereaved adults with IDD (who sought treatment) as getting pushed to the sidelines to deal with their losses in isolation and confusion...

The aberrant proliferation of nucleus pulposus (NP) cells has been reported to be implicated in the pathogenesis of intervertebral disc degeneration (IDD). Previous studies have demonstrated that microRNAs (miRNAs), which are a group of small noncoding RNAs, are critical regulators of cell proliferation in various pathologies. However, the role of miRNA‑96 (miR‑96) in the proliferation of NP cells remains to be determined. In the present study, reverse transcription‑quantitative polymerase chain reaction was used to investigate the expression of miR‑96 in NP tissues from patients with IDD and healthy tissues from patients with traumatic lumbar fracture as the control...

Our group has reported that mature adipocyte-derived dedifferentiated fat (DFAT) cells show multilineage differentiation potential similar to that observed in mesenchymal stem cells. In the present study, we examined whether DFAT cell transplantation could contribute to intervertebral disc regeneration using a rat intervertebral disc degeneration (IDD) model. The IDD was created in Sprague-Dawley rats by puncturing at level of caudal intervertebral disc under fluoroscopy. One week after injury, rat DFAT cells (5 × 10(4), DFAT group, n = 13) or phosphate-buffered saline (PBS, control group, n = 13) were injected into the intervertebral disc...

INTRODUCTION: Factors promoting nerve cell ingrowth are considered responsible for chronic back pain resulting from the intervertebral disc degeneration (IDD). One of the recent exploratory IDD treatments is stem cell transplantation therapy. The CD271 (low-affinity nerve growth factor receptor) has been identified as a marker of the most homogeneous mesenchymal stem cell (MSC) subset. It is capable of promoting differentiation along adipogenic, osteogenic and chondrogenic lineages and producing significantly higher levels of cytokines as compared to the total population of plastic adherence-mesenchymal stem cells (PA-MSCs)...

Intervertebral disc degeneration (IDD) is thought to be the primary cause of low back pain, a severe public health problem worldwide. Current therapy for IDD aims to alleviate the symptoms and does not target the underlying pathological alternations within the disc. Activation of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway protects against IDD, which is attributed to increase of ECM content, prevention of cell apoptosis, facilitation of cell proliferation, induction or prevention of cell autophagy, alleviation of oxidative damage, and adaptation of hypoxic microenvironment...

Teriflunomide is an oral therapy approved for the treatment of relapsing remitting multiple sclerosis (MS), showing both anti-inflammatory and antiviral properties. Currently, it is uncertain whether one or both of these properties may explain teriflunomide's beneficial effect in MS. Thus, to learn more about its mechanisms of action, we evaluated the effect of teriflunomide in the Theiler's encephalomyelitis virus-induced demyelinating disease (TMEV-IDD) model, which is both a viral infection and an excellent model of the progressive disability of MS...
