Preclinical evidence suggests that high-dose hypofractionated ionizing radiation (IR) can enhance anti-tumor immunity and result in significant tumor control when combined with immune checkpoint blockade (ICB). However, low-dose daily fractioned IR used for many tumor types including head and neck squamous cell carcinoma results in lymphopenia and may be immunosuppressive. We compared immune correlates, primary tumor and abscopal tumor control rates following the addition of PD-1 mAb to either high-dose hypofractioned (8Gyx2) or low-dose daily fractionated (2Gyx10) IR in syngeneic models of cancer...

The aim of this study was to investigate whether elimination of multifidus muscle in rats causes intervertebral disc (IVD) degeneration similar to that found after IVD lesion. Data were obtained from 36 male Wistar rats randomly assigned to one of three groups: (i) IVD lesion, in which the L4/L5 IVD was stabbed; (ii) multifidus muscle resection, in which all multifidus tissue between L3 and L6 was excised bilaterally; (iii) control, in which no intervention was applied. At 7, 14, and 28 days post-intervention, L4/L5 IVDs were harvested for histological analysis; left and right multifidus fascicles between L3 and S1 (from control and IVD lesion animals) and medial longissimus between L1 and S3 (from all animals) were dissected and weighed...

INTRODUCTION: Exercise and heat stress lead to systemic improvements in arterial endothelial function, vascular stiffness, and cardiopulmonary capacity. The improvements in endothelial function may be primarily mediated via increases in shear stress. This study examined whether improvements in arterial function may be achieved in the absence of systemic vascular adaptations. Specifically, we hypothesized that repeated bouts of brief occlusion would improve arterial endothelial function via shear stress-dependent mechanisms...

BACKGROUND: As individuals with musculoskeletal disorders often experience motor impairments, contemporary rehabilitation relies heavily on the use of motor learning principles. However, motor impairments are often associated with pain. While there is substantial evidence that muscle pain interferes with motor control, much less is known on its impact on motor learning, especially on locomotor learning. The objective of the present study was to assess the effects of muscle pain on locomotor learning...

BACKGROUND: Femoroacetabular impingment (FAI) syndrome is common among young active adults and a proposed risk factor for the future development of hip osteoarthritis. Pain is dominant and drives clinical decision-making. Evidence for altered hip joint function in this patient population is inconsistent, making the identification of treatment targets challenging. A broader assessment, considering adjacent body segments (i.e. pelvis, trunk) and individual movement strategies, may better inform treatment programs...

BACKGROUND: Previous research explored muscle activity in four distinct sitting postures with fine-wire electromyography, and found that lumbar multifidus muscle activity increased incrementally between sitting with flat thoracolumbar and lumbar regions, long thoracolumbar lordosis, or short lordosis confined to the lumbar region. This study used similar methods to explore whether people with a history of low back pain provoked by prolonged sitting used different patterns of trunk muscle activity in specific postures...

Immunosuppressive therapy fails to suppress the production of pro-inflammatory cytokines, particularly by CD8+T cells, in stable lung transplant recipients and those undergoing chronic rejection, suggesting that some patients may become relatively resistant to immunosuppressants such as glucocorticoids (GC). We have shown loss of GC receptor (GCR) from the CD8+ cells, and we hypothesized that the drug membrane efflux pump, p-glycoprotein-1 (Pgp), may also be involved in lymphocyte steroid resistance following lung transplant...

The earliest galaxies are thought to have emerged during the first billion years of cosmic history, initiating the ionization of the neutral hydrogen that pervaded the Universe at this time. Studying this 'epoch of reionization' involves looking for the spectral signatures of ancient galaxies that are, owing to the expansion of the Universe, now very distant from Earth and therefore exhibit large redshifts. However, finding these spectral fingerprints is challenging. One spectral characteristic of ancient and distant galaxies is strong hydrogen-emission lines (known as Lyman-α lines), but the neutral intergalactic medium that was present early in the epoch of reionization scatters such Lyman-α photons...

BACKGROUND: Use of magnetic resonance imaging (MRI) brain is restricted in patients with cardiovascular implantable electronic devices (CIEDs). We proposed to determine whether mortality difference exists for patients with non-MRI-conditional CIEDs undergoing brain MRI compared with controls. METHODS AND RESULTS: Retrospective analysis of prospectively collected data was performed to compare all-cause mortality in patients with CIEDs undergoing brain MRI (CIED-MRI) with 3 control groups matched for age, sex, imaging year, and type of CIED: (1) no CIED, brain MRI (no-CIED-MRI); (2) CIED, brain computerized tomography (CT) scan (CIED-CT); and (3) no CIED, brain CT (no-CIED-CT)...

Circulating vitamin B6 levels have been found to be inversely associated with lung cancer. Most studies have focused on the B6 form pyridoxal 5'-phosphate (PLP), a direct biomarker influenced by inflammation and other factors. Using a functional B6 marker allows further investigation of the potential role of vitamin B6 status in the pathogenesis of lung cancer. We prospectively evaluated the association of the functional marker of vitamin B6 status, the 3-hydroxykynurenine:xanthurenic acid ratio (HK:XA), with risk of lung cancer in a nested case-control study consisting of 5,364 matched case control pairs from the Lung Cancer Cohort Consortium (LC3)...

BACKGROUND: Most people experience low back pain (LBP), and it is often ongoing or recurrent. Contemporary research knowledge indicates individual's pain beliefs have a strong effect on their pain experience and management. This study's primary aim was to determine the discourses (patterns of thinking) underlying people's beliefs about what causes their LBP to persist. The secondary aim was to investigate what they believed was the source of this thinking. METHODS: We used a primarily qualitative survey design: 130 participants answered questions about what caused their LBP to persist, and where they learned about these causes...

An outbreak of influenza A(H7N2) virus in cats in a shelter in New York, NY, USA, resulted in zoonotic transmission. Virus isolated from the infected human was closely related to virus isolated from a cat; both were related to low pathogenicity avian influenza A(H7N2) viruses detected in the United States during the early 2000s.

Tractography based on non-invasive diffusion imaging is central to the study of human brain connectivity. To date, the approach has not been systematically validated in ground truth studies. Based on a simulated human brain data set with ground truth tracts, we organized an open international tractography challenge, which resulted in 96 distinct submissions from 20 research groups. Here, we report the encouraging finding that most state-of-the-art algorithms produce tractograms containing 90% of the ground truth bundles (to at least some extent)...

INTRODUCTION: We have previously established a link between impaired phagocytic capacity and deregulated S1P signaling in alveolar macrophages from COPD subjects. We hypothesize that this defect may include a disruption of epithelial-macrophage crosstalk via Spns2-mediated intercellular S1P signaling. METHODS: Primary alveolar macrophages and bronchial epithelial cells from COPD subjects and controls, cell lines, and a mouse model of chronic cigarette smoke exposure were studied...

Abrin, one of the most highly potent toxins in the world, is derived from the plant, Abrus precatorius. Because of its high toxicity, it poses potential bioterror risks. Therefore, a need exists for new reagents and technologies that would be able to rapidly detect abrin contamination as well as lead to new therapeutics. We report here a group of abrin-specific monoclonal antibodies (mAbs) that recognize abrin A-chain, intact A-B chain toxin, and agglutinin by Western blot. Additionally, these mAbs were evaluated for their ability to serve as capture antibodies for a sandwich (capture) ELISA...

Background -Recognition of rates and causes of hard, patient-centered outcomes of death and cerebrovascular event (CVE) after heart rhythm disorder management (HRDM) procedures is an essential step for development of quality improvement programs in electrophysiology laboratories. Our primary aim was to assess and characterize death and CVE (stroke or transient ischemic attack) after HRDM procedures over a 17-year period. Methods -We performed a retrospective cohort study of all patients undergoing HRDM procedures between January 2000 and November 2016 at the Mayo Clinic...

Objective: Neuromodulation is increasingly investigated for the treatment of low back pain (LBP). However, the neurophysiological effects of common neuromodulatory techniques (anodal transcranial direct current stimulation [tDCS] and peripheral electrical stimulation [PES]) have not been investigated in people with chronic LBP. Here we aimed to compare the effect of three neuromodulatory protocols (anodal tDCS, high intensity PES, and a priming protocol of combined tDCS/PES) on primary motor cortex (M1) excitability in people with and without chronic LBP...

Aims: To determine the frequency of implantable cardioverter defibrillator (ICD) therapy following cardiac resynchronization therapy (CRT-D) implantation in super and non-super responders and whether greater improvement in left ventricular (LV) function after CRT is associated with a reduced burden in ICD therapy. Methods and results: This is a two-centre, retrospective study between January 2002 and September 2011. Patients were classified as non-super responders and super-responders based on the post-CRT ejection fraction (EF) of < 50% and ≥50%, respectively...
