Influenza A virus (IAV) infection relies on the action of the hemagglutinin (HA) and neuraminidase (NA) membrane proteins. The HA ligands anchor the IAV virion to the cell's surface by binding the sialic acid (SA) present on the host's receptors while NA is an enzyme capable of cleaving the SA from the extracellular environment. It is believed that the activity of NA ligands increases the motility of the virions favoring the propagation of the infection.

A quantitative model of the mobility of ligand-presenting particles at the interface is pivotal to understanding important systems in biology and nanotechnology. In this work, we investigate the emerging dynamics of particles featuring ligands that selectively bind receptors decorating an interface. The formation of a ligand-receptor complex leads to a molecular bridge anchoring the particle to the surface.

Introduction: Children's Hospitals' Solutions for Patient Safety (SPS) acknowledged a recommendation from the American Academy of Pediatrics to develop education programs on the communication of adverse events with patients and families. SPS set out to create a guide that would outline a standardized disclosure process and provide a training curriculum and tools so that providers would feel better prepared to have effective disclosure conversations.

Methods: SPS disclosure work began with the development of a project team made up of 9 network hospitals.

Background: This study evaluated the effects of the Breath-Body-Mind Workshop (BBMW) (breathing, movement, and meditation) on psychological and physical symptoms and inflammatory biomarkers in inflammatory bowel disease (IBD).

Methods: Twenty-nine IBD patients from the Jill Roberts IBD Center were randomized to BBMW or an educational seminar. Beck Anxiety Inventory, Beck Depression Inventory, Brief Symptom Inventory 18, IBD Questionnaire, Perceived Disability Scale, Perceived Stress Questionnaire, Digestive Disease Acceptance Questionnaire, Brief Illness Perception Questionnaire, fecal calprotectin, C-reactive protein, and physiological measures were obtained at baseline and weeks 6 and 26.

Rationale: There is increasing evidence for the presence of autoantibodies in chronic obstructive pulmonary disease (COPD). Chronic oxidative stress is an essential component in COPD pathogenesis and can lead to increased levels of highly reactive carbonyls in the lung, which could result in the formation of highly immunogenic carbonyl adducts on "self" proteins.

Objectives: To determine the presence of autoantibodies to carbonyl-modified protein in patients with COPD and in a murine model of chronic ozone exposure.

Objectives: This study examines whether M(2) receptors contribute to direct contraction of the detrusor in human neurogenic and idiopathic overactive bladders.

Methods: Control detrusor muscle was obtained from patients undergoing cystectomy for bladder cancer, whilst overactive detrusor muscle was obtained from patients undergoing clam cystoplasty for idiopathic or neurogenic detrusor overactivity. The affinities of a range of subtype selective antagonists (DAMP, darifenacin, methoctramine R0-320-6206, and pirenzepine) were obtained in tissue bath experiments by using carbachol as the agonist.
