#1
N J Hickok, I M Shapiro, A F Chen
With the increase in numbers of joint replacements, spinal surgeries, and dental implantations, there is an urgent need to combat implant-associated infection. In addition to stringent sterile techniques, an efficacious way to prevent this destructive complication is to create new implants with antimicrobial properties. Specifically, these implants must be active in the dental implant environment where the implant is bathed in the glycoprotein-rich salivary fluids that enhance bacterial adhesion, and propagation, and biofilm formation...

OBJECTIVE: Neonatal ICUs and PICUs increasingly admit patients with chronic critical illness: children whose medical complexity leads to recurrent and prolonged ICU hospitalizations. We interviewed participants who routinely care for children with chronic critical illness to describe their experiences with ICU care for pediatric chronic critical illness. DESIGN: Semi-structured interviews. Interviews were transcribed and analyzed for themes. SETTING: Stakeholders came from five regions (Seattle, WA; Houston, TX; Jackson, MS; Baltimore, MD; and Philadelphia, PA)...

PURPOSE: Hematopoietic stem cell transplantation (HCT) is potentially curative for a number of hematologic malignancies, but is associated with high symptom burden. We conducted a randomized sham-controlled trial (RCT) to evaluate efficacy and safety of acupuncture as an integrative treatment for managing common symptoms during HCT. METHODS: Adult patients with multiple myeloma undergoing high-dose melphalan followed by autologous HCT (AHCT) were randomized to receive either true or sham acupuncture once daily for 5 days starting the day after chemotherapy...

REVIEW
Gary P Wormser, Eugene D Shapiro, Franc Strle
Positive blood cultures for Lyme borrelia have been well documented in untreated patients with early Lyme disease. In this report we review the validity of three studies that reported the recovery of Borrelia burgdorferi sensu lato from the blood of a high proportion of patients for whom no evidence was presented, and no claim was made, that the patients had untreated early Lyme disease. In two of the studies the patients had been treated extensively with antibiotics for Lyme disease before the cultures were obtained...

INTRODUCTION: We sought to determine whether intrabronchial oxygenation would provide adequate gas exchange during both anesthesia induced apneic and cardiopulmonary arrest and cardiac massage (CPR). METHODS: Ten pigs underwent general anesthesia with mechanical ventilation. Blood gases were measured in each animal at 4 min intervals for up to 28 min. An intrabronchial catheter (4 L/min O2) was inserted through an endotracheal tube after respirator cessation. Group A animals (6) were resuscitated with the catheter but without CPR...

#7
Adam J Shapiro, Margaret W Leigh
Primary ciliary dyskinesia (PCD) is a genetic disorder causing chronic oto-sino-pulmonary disease. No single diagnostic test will detect all PCD cases. Transmission electron microscopy (TEM) of respiratory cilia was previously considered the gold standard diagnostic test for PCD, but 30% of all PCD cases have either normal ciliary ultrastructure or subtle changes which are non-diagnostic. These cases are identified through alternate diagnostic tests, including nasal nitric oxide measurement, high-speed videomicroscopy analysis, immunofluorescent staining of axonemal proteins, and/or mutation analysis of various PCD causing genes...

STUDY QUESTION: How and where is pro-ovastacin activated and how does active ovastacin regulate zona pellucida hardening (ZPH) and successful fertilization? STUDY FINDING: Ovastacin is partially active before exocytosis and pre-hardens the zona pellucida (ZP) before fertilization. WHAT IS KNOWN ALREADY: The metalloproteinase ovastacin is stored in cortical granules, it cleaves zona pellucida protein 2 (ZP2) upon fertilization and thereby destroys the ZP sperm ligand and triggers ZPH...

Magnetic levitation is a technique for measuring the density and the magnetic properties of objects suspended in a paramagnetic field. We describe a novel magnetic levitation-based method that can specifically detect cell membrane-bound and soluble antigens by measurable changes in levitation height that result from the formation of antibody-coated bead and antigen complex. We demonstrate our method's ability to sensitively detect an array of membrane-bound and soluble antigens found in blood, including T-cell antigen CD3, eosinophil antigen Siglec-8, red blood cell antigens CD35 and RhD, red blood cell-bound Epstein-Barr viral particles, and soluble IL-6, and validate the results by flow cytometry and immunofluorescence microscopy performed in parallel...

BACKGROUND: Impairment of spine rotation is a key concept in several theories explaining the pathogenesis and progression of scoliosis. In previous studies, a more limited range of motion in scoliotic girls compared to their non-scoliotic peers was noted. The Trunk-Pelvis-Hip Angle measurement is a test used to assess the range of motion in the trunk-pelvis-hip complex in the transverse plane. The aim of this study was to assess an immediate effect of Proprioceptive Neuromuscular Facilitation specific mobilization (mPNF) on the angle of trunk rotation and Trunk-Pelvis-Hip Angle range of motion in adolescent girls with double scoliosis...

Many ERα-positive breast cancers develop resistance to endocrine therapy via mutation of estrogen receptors (ER) whose constitutive activation is associated with shorter patient survival. Because there is now a clinical need for new antiestrogens (AE) against these mutant ER, we describe here our development and characterization of three chemically novel AE that effectively suppress proliferation of breast cancer cells and tumors. Our AE are effective against wild type and Y537S and D538G ER, the two most commonly occurring constitutively active ER...

The linear and nonlinear theory of a gyroamplifier using a confocal waveguide is presented. A quasi-optical approach to describing the modes of a confocal waveguide is derived. Both the equations of motion and the mode excitation equation are derived in detail. The confocal waveguide circuit has the advantage of reducing mode competition but the lack of azimuthal symmetry presents challenges in calculating the gain. In the linear regime, the gain calculated using the exact form factor for the confocal waveguide agrees with an azimuthally averaged form factor...

In the field of early intervention, only a few studies of parenting interventions include both participant and facilitator behaviors. Fidelity and supervision (facilitator characteristics) and dosage and satisfaction (participant characteristics) were tested on the outcome of improved parenting style in a sample of 36 parents of young children with disabilities. Results indicated that the facilitator behavior of fidelity was significantly and negatively related to the program outcome of parenting style; no effect was found for the facilitator behavior of supervision...

Because cancer stem cells (CSCs) have been implicated in chemo-resistance, metastasis and tumor recurrence, therapeutic targeting of CSCs holds promise to address these clinical challenges to cancer treatment. VS-4718 and VS-6063 are potent inhibitors of focal adhesion kinase (FAK), a non-receptor tyrosine kinase that mediates cell signals transmitted by integrins and growth factor receptors. We report here that inhibition of FAK kinase activity by VS-4718 or VS-6063 preferentially targets CSCs, as demonstrated by a panel of orthogonal CSC assays in cell line models and surgically resected primary breast tumor specimens cultured ex vivo...
