The effect of outer-sphere environment on alkene epoxidation catalysis using an organic hydroperox-ide oxidant is demonstrated for calix[4]arene-TiIV single-sites grafted on amorphous vs. crystalline delaminated zeotype (UCB-4) silicates as supports. A chelating calix[4]arene macrocycle ligand enforc-es a constant TiIV inner-sphere, as characterized by UV-visible and X-ray absorption spectroscopies, thus enabling the rigorous comparison of outer-sphere environments across different siliceous supports. These outer-sphere environments are characterized by solid-state1 H NMR spectroscopy to comprise proximally organized silanols confined within 12-membered-ring cups in crystalline UCB-4, and are responsible for up to 5-fold enhance-ments in rates of epoxidation by TiIV centers...

Health care increasingly collects patient-reported outcomes (PROs) via web-based platforms. The purpose of this study was to evaluate how patient age influences portal engagement. Patients undergoing elective surgery at a single multispecialty orthopedic practice from September 2014 to February 2017 had access to an online portal to complete PROs, message the clinic, and view physical therapy instructions. A mobile app was optionally available. Age, sex, log-in frequency, PRO completion rates, and number of messages sent were reviewed retrospectively...

PURPOSE: Pancreatic cancer is one of the most devastating diseases with a 5-year survival rate of 3-5%. Here we investigated if circulating tumor cells (CTCs) may predict metastatic spread and survival in pancreatic cancer patients. EXPERIMENTAL DESIGN: In a prospective study we enrolled 69 pancreatic cancer patients. In peripheral blood CTCs were identified by MACS enrichment (anti-cytokeratin/anti-EpCam) and subsequent automated analysis after combined anti-cytokeratin/anti-CD45/DAPI staining...

Aplanobacter agropyri was first described in 1915 by O'Gara and later transferred to the genus Corynebacterium by Burkholder in 1948 but it was not included in the Approved Lists of Bacterial Names in 1980 and, consequently, is not recognized as a validly published species. In the 1980s, bacteria resembling Corynebacterium agropyri were isolated from plant samples stored at the Washington State Mycological Herbarium and from a diseased wheatgrass plant collected in Cardwell, Montana, USA. In the framework of this study, eight additional isolates were recovered from the same herbarium plant samples in 2011...

Animals respond to predators by altering their behavior and physiological states, but the underlying signaling mechanisms are poorly understood. Using the interactions between Caenorhabditis elegans and its predator, Pristionchus pacificus, we show that neuronal perception by C. elegans of a predator-specific molecular signature induces instantaneous escape behavior and a prolonged reduction in oviposition. Chemical analysis revealed this predator-specific signature to consist of a class of sulfolipids, produced by a biochemical pathway required for developing predacious behavior and specifically induced by starvation...

Achieving an osseous fusion across the lumbosacral spine is still challenging in spine surgery. For the long multisegmental fusion surgery, it is crucial to build a robust and substantial foundation, which sometimes necessitates the distal spinal fixation to the pelvis. The pelvic fixation technique involves advancing the screw through the alar, thereby providing more purchase across the sacroiliac joint and into the ilium. The S2 alar iliac screws can obtain immediate stability and proper biomechanical strength of constructs...

BACKGROUND CONTEXT: The systemic response regarding cytokine expression after application of recombinant human Bone Morphogenetic Protein-2 (rhBMP-2) in a rat spinal fusion model has recently been defined1 , but the local response has not. Defining the local cytokine and growth factor response at the fusion site will help explain the roles of these molecules in the fusion process, as well as that of rhBMP-2. Our hypothesis is that application of rhBMP-2 to the fusion site will alter the local levels of cytokines and growth factors throughout the fusion process, in a manner that is different than the systemic response given the tissue-specific effects of rhBMP-2...

Allogeneic blood stem cell transplantation (aBSCT) still is the only curative therapy for patients with myelodysplastic syndromes. While it carries the hope for cure for some patients, it may result in severe toxicity and death from complications or recurrent disease in others. Recent developments have improved patient and donor selection as well as technical aspects of the transplant procedure and post-transplant care, including early detection and treatment of relapse. Areas covered: This review will discuss current stratification tools to identify suitable patients, donors and transplant techniques...

To compare trace mineral (TM) repletion in feedlot steers after depletion by S and Mo, 72 Red Angus steers blocked by BW (253 ± 14 kg) were assigned (6 steers per pen, fed via GrowSafe bunks) to corn silage depletion diets (DEP) supplemented with NRC (1996) recommended concentrations of Cu, Mn, Se, and Zn (CON) or supplemented with 0.3% S (CaSO4), 2 mg of Mo/kg DM, and no added Cu, Mn, Zn, or Se (ANT). Three 62 d TM repletion strategies (REP) were applied within DEP diets on d 89: 1) Multimin90 injection (contains Cu, Mn, Se, Zn) and 100% of recommended Cu, Mn, Zn, and Se from inorganic sources (ITM), 2) saline injection and 150% of recommended TM from inorganic sources (ING), or 3) saline injection and 150% of recommended TM provided as 25% organic and 75% inorganic sources (BLEND)...

BACKGROUND: Patients with congenital diaphragmatic hernia (CDH) have a high residual morbidity rate. We compared self-reported health-related quality of life (HRQoL) between patients with CDH and healthy children. METHODS: Forty-five patients with CDH who were born from January 1, 1990, through February 15, 2015, were matched to healthy, age-matched control participants at a 1:2 ratio. The health records of the study participants were reviewed to determine comorbid conditions, and HRQoL was assessed by both the participants and their parents with the Pediatric Quality of Life Inventory (PedsQL)...

Patients with glioblastoma multiforme (GBM) are at high risk to develop a relapse despite multimodal therapy. Assumedly, glioma stem cells (GSCs) are responsible for treatment resistance of GBM. Identification of specific GSC markers may help to develop targeted therapies. Here, we performed expression analyses of stem cell (ABCG2, CD44, CD95, CD133, ELF4, Nanog, and Nestin) as well as differentiation and microglia markers (GFAP, Iba1, and Sparc) in GBM compared to nonmalignant brain. Furthermore, the role of these proteins for patient survival and their expression in LN18 stem-like neurospheres was analyzed...

PURPOSE: MRI or CT imaging can be used to identify the esophageal location prior to left atrial ablation, but the esophagus may move making the location unreliable when ablating to minimize esophageal injury. The aim of this study was to evaluate esophageal position and movement based on serial MRI imaging with the goal of identifying imaging and clinical characteristics that can predict the esophageal movement. METHODS: Fifty patients undergoing 190 MRI scans were analyzed...

Evolutionary adaptations are occasionally convergent solutions to the same problem. A mutation contributing to a heat tolerance adaptation in Senepol cattle, a New World breed of mostly European descent, results in the distinct phenotype known as slick, where an animal has shorter hair and lower follicle density across its coat than wild type animals. The causal variant, located in the 11th exon of prolactin receptor , produces a frameshift that results in a truncated protein. However, this mutation does not explain all cases of slick coats found in criollo breeds...

Biological sex, a fundamental dimension of internal state, can modulate neural circuits to generate behavioral variation. Understanding how and why circuits are tuned by sex can provide important insights into neural and behavioral plasticity. Here we find that sexually dimorphic behavioral responses to C. elegans ascaroside sex pheromones are implemented by the functional modulation of shared chemosensory circuitry. In particular, the sexual state of a single sensory neuron pair, ADF, determines the nature of an animal's behavioral response regardless of the sex of the rest of the body...

PURPOSE: Deranged metabolism is now recognized as a key causal factor in a variety of heart diseases, and is being studied extensively. However, invasive methods may alter metabolism, and conventional imaging techniques measure tracer uptake but not downstream metabolism. These challenges may be overcome by hyperpolarized MR, a noninvasive technique currently crossing the threshold into human trials. The aim of this study was to image metabolic changes in the heart in response to endogastric glucose bolus and to acute hypertension...

Over the course of their wildly successful proliferation across the earth, the insects as a taxon have evolved enviable adaptations to their diverse habitats, which include adhesives, locomotor systems, hydrophobic surfaces, and sensors and actuators that transduce mechanical, acoustic, optical, thermal, and chemical signals. Insect-inspired designs currently appear in a range of contexts, including antireflective coatings, optical displays, and computing algorithms. However, as over one million distinct and highly specialized species of insects have colonized nearly all habitable regions on the planet, they still provide a largely untapped pool of unique problem-solving strategies...
