The theory of turbulent diffusion of chemically reacting gaseous admixtures developed previously [T. Elperin et al., Phys. Rev. E 90, 053001 (2014)PLEEE81539-375510.1103/PhysRevE.90.053001] is generalized for large yet finite Reynolds numbers and the dependence of turbulent diffusion coefficient on two parameters, the Reynolds number and Damköhler number (which characterizes a ratio of turbulent and reaction time scales), is obtained. Three-dimensional direct numerical simulations (DNSs) of a finite-thickness reaction wave for the first-order chemical reactions propagating in forced, homogeneous, isotropic, and incompressible turbulence are performed to validate the theoretically predicted effect of chemical reactions on turbulent diffusion...

BACKGROUND: Concealed left sided accessory pathways (CLAP) are a cause of SVT in the young. Most are mapped with RV apical/outflow pacing. Rarely, alternative means of mapping are required. We review our experience from 3 pediatric EP centers with a rare form of "hidden" CLAP. METHODS: All patients < 21 years undergoing EP study from 2008-2014 with a "hidden" CLAP (defined as an accessory pathway (AP) for which RV pacing at CL's stable for mapping did not demonstrate eccentric retrograde conduction) were included...

Recent research has shown that infants selectively approach prosocial versus antisocial characters, suggesting that foundations of sociomoral development may be present early in life. Despite this, to date, the mental processes involved in infants' prosocial preferences are poorly understood. To explore a possible role of emotions in early social evaluations, the current studies examined whether four samples of infants and toddlers express different emotional reactions after observing prosocial (giving) versus antisocial (taking) events...

Although genetic factors contribute to almost half of all cases of deafness, treatment options for genetic deafness are limited. We developed a genome-editing approach to target a dominantly inherited form of genetic deafness. Here we show that cationic lipid-mediated in vivo delivery of Cas9-guide RNA complexes can ameliorate hearing loss in a mouse model of human genetic deafness. We designed and validated, both in vitro and in primary fibroblasts, genome editing agents that preferentially disrupt the dominant deafness-associated allele in the Tmc1 (transmembrane channel-like gene family 1) Beethoven (Bth) mouse model, even though the mutant Tmc1 Bth allele differs from the wild-type allele at only a single base pair...

OBJECTIVE: To compare the incidence of incisional hernia (IH) between midline and transverse specimen extraction site in patients undergoing laparoscopic colectomy. BACKGROUND: Midline specimen extraction incision is most commonly used in laparoscopic colectomy, but has high IH risk. IH may be lower for transverse incision. METHODS: A single-center superiority trial was conducted. Eligible patients undergoing laparoscopic colectomy were randomly assigned to midline or transverse specimen extraction...

Grafting density and graft distribution impact the chain dimensions and physical properties of polymers. However, achieving precise control over these structural parameters presents long-standing synthetic challenges. In this report, we introduce a versatile strategy to synthesize polymers with tailored architectures via grafting-through ring-opening metathesis polymerization (ROMP). One-pot copolymerization of an ω-norbornenyl macromonomer and a discrete norbornenyl co-monomer (diluent) provides opportunities to control the backbone sequence and therefore the side chain distribution...

In response to three papers about sex and disability published in this journal, I offer a critique of existing arguments and a suggestion about how the debate should be reframed going forward. Jacob M. Appel argues that disabled individuals have a right to sex and should receive a special exemption to the general prohibition of prostitution. Ezio Di Nucci and Frej Klem Thomsen separately argue contra Appel that an appeal to sex rights cannot justify such an exemption. I argue that Appel's argument fails, but not (solely) for the reasons Di Nucci and Thomsen propose, as they have missed the most pressing objection to Appel's argument: Appel falsely presumes that we never have good reasons to restrict someone's sexual liberty rights...

Background: Heterogeneity in work outcomes is common among individuals with serious mental illness (SMI). Objective: In 2 studies, we sought to examine the efficacy of adding errorless learning, a behavioral training intervention, to evidence-based supported employment to improve SMI work outcomes. Work behavior problems were targeted for intervention. We also explored associations between early work behavior and job tenure. Methods: For both studies (VA: n = 71; community mental health center: n = 91), randomization occurred at the time of job obtainment with participants randomized (1:1) to either errorless learning plus ongoing supported employment or ongoing supported employment alone and then followed for 12 months...

INTRODUCTION: Enhanced recovery pathways (ERP) include a bundle of evidence-based preoperative, intraoperative, and postoperative interventions that together reduce morbidity and length of stay after colorectal surgery. Increased adherence with the bundle is associated with better postoperative outcomes, but adherence is lowest in the postoperative period. Identifying risk factors for lower adherence may help design quality improvement strategies. The aim of this study was to estimate the extent to which patient, procedural, and organizational factors predict adherence to postoperative ERP elements in laparoscopic colorectal surgery...

BACKGROUND: We evaluated selected birth defects over a 9-year period to assess prevalence trends by selected maternal and infant factors. METHODS: Data were pooled from 11 population-based birth defects surveillance programs in the United States for children born between 1999 and 2007. Overall prevalence, as well as 3-year interval prevalence, was calculated for 26 specific birth defects, stratified by maternal age, maternal race/ethnicity, and infant sex. Average annual percent change (AAPC) was calculated for each birth defect...

Epigenetic influences mediating brain iron deposition, oxidative mitochondrial injury, and macroautophagy in Parkinson disease and related conditions remain enigmatic. Here, we show that selective overexpression of the stress protein, heme oxygenase-1 (HO-1) in astrocytes of GFAP.HMOX1 transgenic mice between 8.5 and 19 months of age results in nigrostriatal hypodopaminergia associated with locomotor incoordination and stereotypy; downregulation of tyrosine hydroxylase, DAT, LMX1B, Nurr1, Pitx3 and DJ-1 mRNA and/or protein; overproduction of α-synuclein and ubiquitin; oxidative stress; basal ganglia siderosis; mitochondrial damage/mitophagy; and augmented GABAergic systems (increased GABA, GAD67 and reelin)...

BACKGROUND: Approximately 10% of patients with lateral epicondylitis go on to have surgical treatment; however, multiple surgical treatment options exist. The purpose of this study was to review the literature for the clinical outcomes of open, arthroscopic, and percutaneous treatment of lateral epicondylitis. The authors hypothesized that the clinical outcome of all 3 analyzed surgical treatments would be equivalent. METHODS: A systematic review was performed using PubMed, Cochrane Central Register of Controlled Trials, and Google Scholar in July 2016 to compare the functional outcome, pain, grip strength, patient satisfaction, and return to work at 1-year follow-up for open, arthroscopic, and percutaneous treatment of lateral epicondylitis...

Cochlear synaptopathy can result from various insults, including acoustic trauma, aging, ototoxicity, or chronic conductive hearing loss. For example, moderate noise exposure in mice can destroy up to ∼50% of synapses between auditory nerve fibers (ANFs) and inner hair cells (IHCs) without affecting outer hair cells (OHCs) or thresholds, because the synaptopathy occurs first in high-threshold ANFs. However, the fiber loss likely impairs temporal processing and hearing-in-noise, a classic complaint of those with sensorineural hearing loss...

REVIEW
M Charles Liberman
The classic view of sensorineural hearing loss has been that the primary damage targets are hair cells and that auditory nerve loss is typically secondary to hair cell degeneration. Recent work has challenged that view. In noise-induced hearing loss, exposures causing only reversible threshold shifts (and no hair cell loss) nevertheless cause permanent loss of >50% of the synaptic connections between hair cells and the auditory nerve. Similarly, in age-related hearing loss, degeneration of cochlear synapses precedes both hair cell loss and threshold elevation...

Schizophrenia is a neuropsychiatric disorder that features neural oxidative stress and glutathione (GSH) deficits. Oxidative stress is augmented in brain tissue of GFAP.HMOX1 transgenic mice which exhibit schizophrenia-relevant characteristics. The whey protein isolate, Immunocal® serves as a GSH precursor upon oral administration. In this study, we treated GFAP.HMOX1 transgenic mice daily with either Immunocal (33mg/ml drinking water) or equivalent concentrations of casein (control) between the ages of 5 and 6...
