Low back pain (LBP) is the most common pain syndrome, and is an enormous burden and cost generator for society. Lumbar facet joints (FJ) constitute a common source of pain, accounting for 15-45% of LBP. Facet joint degenerative osteoarthritis is the most frequent form of facet joint pain. History and physical examination may suggest but not confirm facet joint syndrome. Although imaging (radiographs, MRI, CT, SPECT) for back pain syndrome is very commonly performed, there are no effective correlations between clinical symptoms and degenerative spinal changes...

Adsorbed atomic H (H* ads ) facilitates indirect pathways play a major role in the electrochemical removal of various priority pollutants. It is crucial to identify the atomic sites responsible for the provision of H* ads . Herein, through a systematic study of the distribution of H* ads on Pd nanocatalysts with different sizes and, more importantly, deliberately controlled relative abundance of surface defects, we uncovered the central role of defects in the provision of H* ads . Specifically, the H* ads generated on Pd in an electrochemical process increased markedly upon introducing defect sites by changing the morphology to ultrathin polycrystalline Pd nanowires (NWs), while dramatically reduced upon decreasing the number of surface defects through an annealing treatment...

Mõttus and colleagues (2017) reported evidence that the unique variance in specific personality characteristics captured by single descriptive items often displayed trait-like properties of cross-rater agreement, rank-order stability, and heritability. They suggested that the personality hierarchy should be extended below facets to incorporate these specific characteristics, called personality nuances. The present study attempted to replicate these findings, employing data from 6,287 individuals from 6 countries (Australia, Canada, Czech Republic, Denmark, Japan, and United States)...

ZnS nanostructures of barbell-shaped porous and hollow nanoplates with a controlled amount of S vacancies have been facilely fabricated via the hydrothermal treatment of ZnS(en)0.5 (en = ethylenediamine) nanoplates. The amount of S vacancies as well as the morphologies of ZnS nanostructures have been controlled by adjusting the hydrolysis time; the layered structure of ZnS(en)0.5 nanoplates decomposes to yield discrete ZnS nanoparticles at two end facets of template nanoplates, producing barbell-shaped porous and hollow ZnS nanoplates with abundant S vacancies finally...

Background and aims The evidence for interventional treatment of thoracic facet joint pain remains limited. This is partly due to inconsistency of the path of thoracic medial branches and a lower incidence of thoracic facet pain among spine pain patients. The purpose of this study is to evaluate the efficacy of bipolar radiofrequency (RF) neurotomy of medial branches for treating chronic thoracic facet joint pain. Methods This is a retrospective record review of all patients diagnosed to have thoracic facet pain with diagnostic block and subsequently treated with bipolar RF neurotomy of medial branch between January 2012 and December 2015...

INTRODUCTION: Lumbar pain affects between 60-90% of people. It is a frequent cause of disability in adults. Pain may be generated by different anatomical structures such as the facet joint. However, nowadays pain produced by the facet joint has no clinical diagnosis. Therefore, the purpose of this article is to propose a clinical diagnostic scale for lumbar facet syndrome. MATERIALS AND METHODS: The study was conducted by means of 6 phases as follows, Phase 1, a systematic review of the literature was performed regarding the clinical diagnosis of facet-based lumbar pain based on the PRISMA checklist; Phase 2, a list of signs and symptoms proposed for diagnosis lumbar pain of facet origin was made...

BACKGROUND: IL-17A has recently emerged as a potential target that regulates the extensive inflammation and abnormal bone formation observed in ankylosing spondylitis (AS). Blocking IL-17A is expected to inhibit bony ankylosis. Here, we investigated the effects of anti IL-17A agents in AS. METHODS: TNFα, IL-17A, and IL-12/23 p40 levels in serum and synovial fluid from patients with ankylosing spondylitis (AS), rheumatoid arthritis (RA), osteoarthritis (OA), or healthy controls (HC) were measured by ELISA...

BACKGROUND: Neural blockade of the cervical medial branches is a validated procedure in the diagnosis and treatment of cervical zygapophyseal joint pain. Fluoroscopic visualization of the lower cervical medial branch target zones (CMBTZs) in lateral view is sometimes challenging or not possible due to the patient's shoulders obscuring the target. Large shoulders and short necks often exacerbate the problem. Clear visualization is critical to accuracy and safety. OBJECTIVE: We aim to describe a method for optimal fluoroscopic visualization of the lower CMBTZs using a modified swimmer's view...

BACKGROUND: Among the various causes of vertigo, the so-called cervicogenic vertigo (CV) has been the most controversial. However, perturbations of proprioceptive signals and abnormal activity of the cervical afferents can induce vertigo. Medial branch blocks (MBBs) are a diagnostic tool designed to test whether a patient's neck pain is mediated by one or more of the medial branches of the dorsal rami of the spinal nerve. It is unknown whether MBBs are also suitable for testing symptoms other than pain...

The epidemiology of cutaneous malignant melanoma (CMM) has a number of facets that do not fit with sunlight and ultraviolet light as the primary etiologic agents. Indoor workers have higher incidence and mortality rates of CMM than outdoor workers; CMM occurs in body locations never exposed to sunlight; CMM incidence is increasing in spite of use of UV blocking agents and small changes in solar radiation. Installation of two new fluorescent lights in the milking parlor holding area of a Minnesota dairy farm in 2015 caused an immediate drop in milk production...

Understanding the function and molecular relevance of distinct miRNAs in endothelial cells (ECs) paves avenues for possible therapeutic intervention by targeting epigenetic mechanisms in vascular endothelial dysfunction, one of the major complications of type 2 diabetes mellitus (T2DM). MiR-342-3p, an obesity-associated miRNA, has recently been shown to be significantly upregulated in human angiosarcoma compared to benign hemangioma, indicating its potential involvement as a proangiogenic factor. Herein, we show that endothelial miR-342-3p expression was significantly compromised in T2DM organisms and this inhibition powerfully blocked vasculogenesis in vivo by repressing endothelial proliferation and migration...

Despite significant advances toward accurate tuning of the size and shape of colloidal nanoparticles, the precise control of the surface chemistry thereof remains a grand challenge. It is desirable to conjugate functional bio-molecules onto the selected facets of nanoparticles owing to the versatile capabilities rendered by the molecules. We report here facet-selective conjugation of DNA molecules onto upconversion nanoparticles via ligand competition reaction. Different binding strengths of phosphodiester bonds and phosphate groups on DNA and the surfactant molecules allow one to create heterogeneous bio-chemistry surface for upconversion nanoparticles...
