#1
Deepti Srivastava, C Heath Turner, Erik E Santiso, Keith E Gubbins
When confined within nano-porous carbons (activated carbon fibers or carbon nanotubes) having pore widths of about 1 nm, nitric oxide is found to react completely to form the dimer, (NO)2, even though almost no dimers are present in the bulk gas phase in equilibrium with the pore phase. Moreover, the yield of dimer is unchanged on varying the temperature over the range studied in the experiments. Earlier molecular simulation studies showed a significant increase in dimer formation in carbon nano-pores, but the dimer yield was considerably less than that found in the experiments, and decreased rapidly as the temperature was raised...

Wildflower seeds are routinely spread along highways and thoroughfares throughout North America as part of federal beautification policy, but the genetic effect of the introduction of these cultivated populations on wild populations of the same species is unknown. Interbreeding may occur between these seeded and wild populations, resulting in several possible outcomes. Here we sample 187 individuals in 12 matched pairs of neighboring wild and seeded populations of the Texas bluebonnet (Lupinus texensis), a species popular in commercially available wildflower seed mixes used by both the Texas Department of Transportation and the public...

Over the last 25 years, research on biodiversity has expanded dramatically, fuelled by increasing threats to the natural world. However, the number of published studies is heavily weighted towards certain taxa, perhaps influencing conservation awareness of and funding for less-popular groups. Few studies have systematically quantified these biases, although information on this topic is important for informing future research and conservation priorities. We investigated: i) which animal taxa are being studied; ii) if any taxonomic biases are the same in temperate and tropical regions; iii) whether the taxon studied is named in the title of papers on biodiversity, perhaps reflecting a perception of what biodiversity is; iv) the geographical distribution of biodiversity research, compared with the distribution of biodiversity and threatened species; and v) the geographical distribution of authors' countries of origin...

BACKGROUND: Infertility is prevalent and stigmatized in sub-Saharan Africa. Self-rated health, a subjective indicator that has been consistently related to objectively measured health, may be useful in evaluating the relationship between women's infertility and health. METHODS: Data were from surveys conducted from July 2014 to January 2015 with women aged 15 to 39 years (n = 915) as part of the initial assessment in a cohort study in Lilongwe district, Malawi...

Businesses marketing unproven stem cell interventions proliferate within the U.S. and in the larger global marketplace. There have been global efforts by scientists, patient advocacy groups, bioethicists, and public policy experts to counteract the uncontrolled and premature commercialization of stem cell interventions. In this commentary, we posit that medical societies and associations of health care professionals have a particular responsibility to be an active partner in such efforts. We review the role medical societies can and should play in this area through patient advocacy and awareness initiatives...

Paul Paddle, Inna Husain, Christine Moniz, Scott Turner, Ramon Arturo Franco
Objectives: Adductor spasmodic dysphonia (AdSD) is a focal dystonia predominantly involving the laryngeal adductor muscles. AdSD is reported to be a largely non-progressive neurological disorder, though fluctuations in symptom severity do occur. Repeated laryngeal onabotulinumtoxinA (BTX-A) injections are the primary management for AdSD. A number of studies have demonstrated long-term dose stability as evidence of this long-term disease stability. Methods: A retrospective review was performed on all patients undergoing BTX-A injections for AdSD from April 1994 to September 2013 by a single laryngologist at a tertiary referral laryngology center...

Background: Parents with cancer have high rates of psychological morbidity, and their children are at risk of poor psychosocial outcomes, particularly in the context of parental distress and poor family communication. Parents express concerns about the impact of cancer on their children and report a lack of professional guidance in meeting their children's needs. Few parenting interventions exist and current interventions have extensive infrastructure demands making them unsuitable for routine use in most health settings...

The emergence of Clostridium difficile as a significant human diarrheal pathogen is associated with the production of highly transmissible spores and the acquisition of antimicrobial resistance genes (ARGs) and virulence factors. Unlike the hospital associated C. difficile RT027 lineage, the community associated C. difficile RT078 lineage is isolated from both humans and farm animals; however, the geographical population structure and transmission networks remain unknown. Here we applied whole genome phylogenetic analysis of 248 C...

Objectives: Ceftaroline is often used in durations greater than that studied in clinical trials. Several retrospective, non-comparative studies have suggested a higher than anticipated incidence of neutropenia in patients receiving prolonged treatment with ceftaroline. We sought to determine if ceftaroline was associated with neutropenia by comparing the incidence with ceftaroline treatment with treatment with several comparative antibiotics. Methods: Patients receiving 14 or more consecutive days of treatment with ceftaroline were compared with patients receiving cefazolin, daptomycin, linezolid, nafcillin or vancomycin (control group)...

BACKGROUND: Laparoscopic fundoplication is an accepted surgical management of refractory gastro-esophageal reflux disease (GERD). The use of high resolution esophageal manometry (HRM) in preoperative evaluation is often applied to determine the degree of fundoplication to optimize reflux control while minimizing adverse sequela of postoperative dysphagia. OBJECTIVE: Assess the role of preoperative HRM in predicting surgical outcomes, specifically risk assessment of postoperative dysphagia and quality of life, among patients receiving laparoscopic Nissen fundoplication for GERD with immediate postoperative (< 4 weeks clinic), short-term (3-month clinic), and long-term (34 ± 10...

Survival for hypoplastic left heart syndrome patients following the Norwood procedure is 71-90%. Mortality in patients with Turner's syndrome and hypoplastic left heart syndrome after conventional palliation (Norwood operation) has been reported as high as 80%. This questions the approach of traditional staged palliation. Here, we report a patient with hypoplastic left heart syndrome and Turner's syndrome bridged to orthotopic heart transplantation following a hybrid procedure.

OBJECTIVES: Although large polyps are known to harbor more advanced neoplasia than small polyps, the extent of the relationship between size and type is not fully known. The study aim was to establish benchmarks for the prevalence of different histologic polyp types among varying size categories. METHODS: The Miraca Life Sciences Database is an electronic repository of histopathologic patient records from private practices throughout the United States. We extracted the records of 483,998 unique patients who underwent colonoscopy with polypectomy between January 2008 and December 2014...

The irrational performance beliefs inventory (iPBI) was developed to measure irrational beliefs within performance domains such as sport, academia, business, and the military. Past research indicates that the iPBI has good construct, concurrent, and predictive validity, but the test-retest reliability of the iPBI has not yet been examined. Therefore, in the present study the iPBI was administered to university sport and exercise students (n = 160) and academy soccer athletes (n = 75) at three-time points...

Purpose: To study the effect and time course of body position changes on IOP in nonhuman primates. Methods: We recorded continuous bilateral IOP measurements with a wireless telemetry implant in three rhesus macaques in seven different body positions. IOP measurements were acquired in the seated-upright, standing, prone, supine, right and left lateral decubitus positions (LDPs), and head-down inverted positions. Continuous IOP was recorded for 90 seconds in each position before returning to a supine reference position until IOP stabilized; measurements were averaged after IOP stabilized at each position...
