STUDY DESIGN: Retrospective cohort comparative study. OBJECTIVE: To evaluate presurgical and surgical factors that affect return to work (RTW) status after multilevel cervical fusion, and to compare outcomes after multilevel cervical fusion for degenerative disc disease (DDD) versus radiculopathy. SUMMARY OF BACKGROUND DATA: Cervical fusion provides more than 90% of symptomatic relief for radiculopathy and myelopathy. However, cervical fusion for DDD without radiculopathy is considered controversial...

Ependymoma is a malignant pediatric brain tumor, often incurable under the current treatment regimen. We aimed to evaluate the expression of microRNAs (miRs) in pediatric ependymoma tumors in an attempt to identify prognostic molecular markers which would lead to potential therapeutic targets. Following miR-array expression analysis, we focused on 9 miRs that correlated with relapse which were further validated by quantitative real time PCR (qRT-PCR) in a cohort of 67 patients. Western blotting and immunohistochemistry were used to measure target protein expression in 20 and 34 tumor samples, respectively...

Blindness is associated with well-documented changes to the morphometry and function of the occipital cortex. By comparison, its impact on the perisylvian regions in the superior temporal plane (STP) is poorly understood, with many studies reporting null findings on this issue. Here we re-approach this question using a morphometric analysis that relied on fine-scale, manual annotation of 13 sub-regions within the STP and that quantified both univariate and multivariate differences in morphometry. We applied these analyses to both cortical thickness (CT) and surface area (SA) data from congenitally and late blind, as compared to two matched sighted control groups...

BACKGROUND: High tumor mutational burden (TMB) is an emerging biomarker of sensitivity to immune checkpoint inhibitors and has been shown to be more significantly associated with response to PD-1 and PD-L1 blockade immunotherapy than PD-1 or PD-L1 expression, as measured by immunohistochemistry (IHC). The distribution of TMB and the subset of patients with high TMB has not been well characterized in the majority of cancer types. METHODS: In this study, we compare TMB measured by a targeted comprehensive genomic profiling (CGP) assay to TMB measured by exome sequencing and simulate the expected variance in TMB when sequencing less than the whole exome...

Motivation: Sources of variability in experimentally derived data include measurement error in addition to the physical phenomena of interest. This measurement error is a combination of systematic components, originating from the measuring instrument, and random measurement errors. Several novel biological technologies, such as mass cytometry and single-cell RNA-seq, are plagued with systematic errors that may severely affect statistical analysis if the data is not properly calibrated...

Background Haspin (haploid germ cell-specific nuclear protein kinase) is an atypical serine/threonine-protein kinase that was for a long time considered an inactive pseudokinase due to low degree of structural homology of Haspin with the 'classical' protein kinases. However, the discovery of Haspin-catalyzed phosphorylation of histone H3 at Thr3 residue unveiled importance of Haspin in mitosis and provided yet another link between mitotic phosphorylation pathways and chromatin modifications. Results In this review of 111 publications, we have (1) briefly summarized catalytic properties and physiological roles of Haspin, (2) focussed on the architecture of Haspin and mechanisms behind its substrate recognition, (3) provided detailed insight into the advances in the development and characterization of Haspin-selective inhibitors, and (4) given overview of inhibitor scaffolds that despite targeting other protein kinases feature Haspin as a common off-target...

Adenosine A1 receptors (A1 Rs) interact negatively with dopamine D1 receptors (D1 Rs) in neurons of the basal ganglia's direct pathway, while adenosine A2A receptors (A2A Rs) negatively interact with dopamine D2 receptors (D2 Rs) in indirect-pathway neurons. The aim of this study was to investigate the cerebral density of A1 Rs in Parkinson's disease (PD) in its early stages, using PET scans with the radioligand 8-dicyclopropylmethyl-1-(11) C-methyl-3-propylxanthine ((11) C-MPDX). We studied 10 drug-naïve patients with early PD...

We assessed the effect of a single bout of intense exercise on the adaptation and consolidation of a rotational visuomotor task, together with the effect of the order of exercise presentation relative to the learning task. Healthy adult participants (n = 29) were randomly allocated to one of three experimental groups: (1) exercise before task practice, (2) exercise after task practice, and (3) task practice only. After familiarization with the learning task, participants undertook a baseline practice set. Then, four 60° clockwise rotational sets were performed, comprising an adaptation set and three retention sets at 1 h, 24 h, and 7 days after the adaptation set...

Few studies have investigated the appropriateness of antibiotic use in postdisaster settings. We retrospectively evaluated clinical databases on health care delivered at clinics near shelters set up after the Great East Japan Earthquake, 2011. We defined appropriate, acceptable, and inappropriate antibiotic use for each diagnostic category, by applying and adopting precedent studies and clinical guidelines. From March to July, 2011, a total of 23,704 clinic visits occurred at 98 shelters with 7934 residents...

Sticholysin II is a pore-forming toxin produced by the sea anemone Stichodactyla helianthus that belongs to the actinoporin protein family. The high affinity of actinoporins for sphingomyelin (SM)-containing membranes has been well documented. However, the molecular determinants that define this affinity have not been fully clarified. Here, we have examined the binding and permeabilizing activity of StII to different single and mixed lipidic systems by combining lipid monolayers, liposomes, and permeabilizing assays...

Spatial heterogeneity of transcriptional and genetic markers between physically isolated biopsies of a single tumor poses major barriers to the identification of biomarkers and the development of targeted therapies that will be effective against the entire tumor. We analyzed the spatial heterogeneity of multiregional biopsies from 35 patients, using a combination of transcriptomic and genomic profiles. Medulloblastomas (MBs), but not high-grade gliomas (HGGs), demonstrated spatially homogeneous transcriptomes, which allowed for accurate subgrouping of tumors from a single biopsy...

Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis in patients at high or prohibitive surgical risk. Nevertheless, long-term clinical and echocardiographic data are still lacking. We carried out an analysis of 560 consecutive patients who underwent TAVI at our institution from 2008 to 2016 to evaluate temporal changes in TAVI characteristics, predictors of 1-year and long-term outcomes, and to compare the performance of the early- and new-generation valve systems...

X-linked hypophosphataemic rickets (XLH), caused by mutations in the PHEX gene, has traditionally been treated with a combination of high doses of oral phosphate and active vitamin D metabolites with the goal of normalizing serum phosphate concentration to a degree sufficient to heal the rickets while avoiding iatrogenic complications. Although XLH is caused by elevated serum levels of fibroblast growth factor 23 (FGF23), parathyroid hormone (PTH) still plays a role through its independent effect on the tubular threshold for phosphate per glomerular filtration rate (TP/GFR), which influences serum phosphate concentration...

Necroptosis is a form of regulated necrosis that results in cell death and content release after plasma membrane permeabilization. However, little is known about the molecular events responsible for the disruption of the plasma membrane. Here, we find that early increase in cytosolic calcium in TNF-induced necroptosis is mediated by treatment with a Smac mimetic via the TNF/RIP1/TAK1 survival pathway. This does not require the activation of the necrosome and is dispensable for necroptosis. Necroptosis induced by the activation of TLR3/4 pathways does not trigger early calcium flux...

Hidden caries is a dentinal lesion beneath the dentinoenamel junction, visible on radiographs. A single report described this lesion in primary dentition. This case report describes a case of hidden caries in a mandibular second primary molar, misdiagnosed as malignant swelling. A 3-year-old white girl was referred to the Department of Pediatric Dentistry with a chief complaint of pain and extraoral swelling on the right side of the mandible for the last 3 months. She was earlier referred to the surgical department for biopsy of the lesion...
