#1
Alex Gillespie, Julie Hald
When interacting with people with aphasia, communication partners use a range of subtle strategies to scaffold, or facilitate, expression and comprehension. The present article analyses the unintended effects of these ostensibly helpful acts. Twenty people with aphasia and their main communication partners (n = 40) living in the UK were video recorded engaging in a joint task. Three analyses reveal that: (1) scaffolding is widespread and mostly effective, (2) the conversations are dominated by communication partners, and (3) people with aphasia both request and resist help...

Accurate modeling and numerical simulation of reaction kinetics is a topic of steady interest. We consider the spatiotemporal chemical master equation (ST-CME) as a model for stochastic reaction-diffusion systems that exhibit properties of metastability. The space of motion is decomposed into metastable compartments, and diffusive motion is approximated by jumps between these compartments. Treating these jumps as first-order reactions, simulation of the resulting stochastic system is possible by the Gillespie method...

OBJECTIVE: No standard protocol exists to determine when a patient is ready and able to be discharged from voice therapy. The aim of the present study was to determine what factors speech-language pathologists (SLPs) deem most important when discharging a patient from voice therapy. A second aim was to determine if responses differed based on years of voice experience. METHODS: Step 1: Seven voice-specialized SLPs generated a list of items thought to be relevant to voice therapy discharge...

Purpose: Retinal prostheses provide vision to blind patients by eliciting phosphenes through electrical stimulation. This study explored whether character identification and image localization could be achieved through direct multiple-electrode stimulation with a suprachoroidal retinal prosthesis. Methods: Two of three retinitis pigmentosa patients implanted with a suprachoroidal electrode array were tested on three psychophysical tasks. Electrode patterns were stimulated to elicit perception of simple characters, following which percept localization was tested using either static or dynamic images...

Antigenic drift and shift of influenza strains underscore the need for broadly protective influenza vaccines. One strategy is to design immunogens that elicit B cell responses against conserved epitopes on the hemagglutinin (HA) stem. To better understand the elicitation of HA stem-targeted B cells to group 1 and group 2 influenza subtypes, we compared the memory B cell response to group 2 H7N9 and group 1 H5N1 vaccines in humans. Upon H7N9 vaccination, almost half of the HA stem-specific response recognized the group 1 and group 2 subtypes, whereas the response to H5N1 was largely group 1-specific...

Porcine epidemic diarrhea virus (PEDV) causes acute diarrhea, dehydration in pigs, and high mortality rates in piglets <3 weeks of age. Maternal immunity protects piglets, but information on vaccination before or after natural infection in endemically exposed sow herds is limited. Currently, the recovery goal in sow units infected with PEDV is to become fully naive again or use natural virus infection to develop immune gilts through a feedback program before introduction into the sow herd. Since neutralizing antibodies in the gut are critical for protection against enteric viral infections such as PEDV, we evaluated the effect of a conditionally licensed, adjuvanted inactivated PEDV vaccine on neutralizing antibody levels in milk and colostrum in both naive and previously naturally exposed sow herds...

In late mitosis and G1, origins of DNA replication must be "licensed" for use in the upcoming S phase by being encircled by double hexamers of the minichromosome maintenance proteins MCM2-7. A "licensing checkpoint" delays cells in G1 until sufficient origins have been licensed, but this checkpoint is lost in cancer cells. Inhibition of licensing can therefore kill cancer cells while only delaying normal cells in G1. In a high-throughput cell-based screen for licensing inhibitors we identified a family of 2-arylquinolin-4-amines, the most potent of which we call RL5a...

RNA secondary structure folding kinetics is known to be important for the biological function of certain processes, such as the hok/sok system in E. coli. Although linear algebra provides an exact computational solution of secondary structure folding kinetics with respect to the Turner energy model for tiny ([Formula: see text]20 nt) RNA sequences, the folding kinetics for larger sequences can only be approximated by binning structures into macrostates in a coarse-grained model, or by repeatedly simulating secondary structure folding with either the Monte Carlo algorithm or the Gillespie algorithm...

BACKGROUND: Nerve injuries occur in approximately 11% of pediatric extension supracondylar humerus fractures (SCHF), yet there is scarce literature to guide clinicians on management. The primary goal of this study was to report the presentation, treatment, and outcome of motor nerve injuries associated with extension SCHF. Our secondary goal was to determine which injury and treatment factors were associated with prolonged motor nerve recovery. METHODS: Two hundred forty-four traumatic nerve injuries associated with extension SCHF treated at a single institution between 1996 and 2012 were reviewed...

BACKGROUND: Multimorbidity, defined as the presence of at least two chronic conditions, becomes increasingly common in older people and is associated with poorer health outcomes and significant polypharmacy. The National Institute for Clinical Excellence (NICE) recently published a multimorbidity guideline that advises providing an individualised medication review for all people prescribed 15 or more repeat medicines. This study incorporates this guideline and aims to assess the effectiveness of a complex intervention designed to support general practitioners (GPs) to reduce potentially inappropriate prescribing and consider deprescribing in older people with multimorbidity and significant polypharmacy in Irish primary care...

Melphalan is a cytotoxic chemotherapy used to treat patients with multiple myeloma (MM). Bone resorption by osteoclasts, by remodeling the bone surface, can reactivate dormant MM cells held in the endosteal niche to promote tumor development. Dormant MM cells can be reactivated after melphalan treatment; however, it is unclear whether melphalan treatment increases osteoclast formation to modify the endosteal niche.Melphalan treatment of mice for 14 days decreased bone volume and the endosteal bone surface, and this was associated with increases in osteoclast numbers...
