To investigate gender stereotypes, demonstrated engineering aptitude, and attitudes, children (N=105) solved an engineering problem using either pastel-colored or primary-colored materials. Participants also evaluated the acceptability of denial of access to engineering materials based on gender and counter-stereotypic preferences (i.e., a boy who prefers pastel-colored materials). Whereas material color was not related to differences in female participants' performance, younger boys assigned to pastel materials demonstrated lower engineering aptitude than did other participants...

BACKGROUND: HIT complicated by severe thrombocytopenia and thrombosis can pose significant treatment challenges. Use of alternative anticoagulants in this setting may increase bleeding risks, especially in patients who have a protracted disease course. Additional therapies are lacking in this severely affected patient population. METHODS: We describe three HIT patients who had severe thromboembolism and prolonged thrombocytopenia refractory to standard treatment but achieved an immediate and sustained response to intravenous immunoglobulin G (IVIg) therapy...

BACKGROUND: The optimal antithrombotic regimen for urgent percutaneous coronary interventions (PCI) following thrombolytic therapy for ST segment myocardial infarction (STEMI) is currently unknown. METHODS: We performed a retrospective analysis of all patients referred to our institution from January 2005 to July 2014 who underwent urgent PCI within 24 hr after receiving thrombolytic therapy. The patients were divided into three cohorts based on the anticoagulation strategy during PCI-bivalirudin, heparin alone or heparin plus Glycoprotein IIb/IIIa inhibitor (GPI)...

Youth often hold group norms that perpetuate inequality. One way these norms can be changed is by challenging these norms by choosing to include new members into these groups who hold morally just norms. In the current study, children's and adolescents' inclusion decisions and social reasoning about challenging group norms through inclusion were investigated. The sample included 9-10 (children) and 13-14 year-olds (adolescents) (N = 673, 54.4% female). Participants supported including challengers into groups holding norms supporting relational aggression and unequal allocation of resources, but they were less likely to support including a challenger into a physically aggressive group...

The United States has substantially higher levels of firearm violence than most other developed countries. Firearm violence is a significant and preventable public health crisis. Mental illness is a weak risk factor for violence despite popular misconceptions reflected in the media and policy. That said, mental health professionals play a critical role in assessing their patients for violence risk, counseling about firearm safety, and guiding the creation of rational and evidence-based public policy that can be effective in mitigating violence risk without unnecessarily stigmatizing people with mental illness...

Extraintestinal pathogenic Escherichia coli (ExPEC) strains are typically benign within the mammalian gut, but can disperse to extraintestinal sites to cause disease. As occupation of the intestinal tract is often a prerequisite for ExPEC-mediated pathogenesis, we set out to understand how ExPEC colonizes this niche. A screen using transposon sequencing (Tn-seq) was performed to search for genes within the ExPEC isolate F11 that are important for growth in intestinal mucus, which is thought to be a major source of nutrients for E...

Virulence plasmids and antibiotic resistance plasmids are usually maintained separately in Salmonella spp., however we report an instance of a hybrid plasmid (pN13-01125) in Salmonella Dublin. The complete sequence of the 172,265 bp plasmid suggested that pN13-01125 is comprised of the previously described pSDVr and pSH696_135 plasmids and that the mechanism of hybridization likely involved IS6 (IS26) insertion sequence elements. The plasmid has a low conjugation frequency, confers resistance to six classes of antimicrobials, and contains a complete spv virulence operon...

Carbapenem-resistant Enterobacter cloacae complex isolates submitted to a reference laboratory from 2010 to 2015 were screened by PCR for seven common carbapenemase gene groups, namely, KPC, NDM, OXA-48, VIM, IMP, GES, and NMC-A/IMI. Nineteen of the submitted isolates (1.7%) were found to harbor Ambler class A blaNMC-A or blaIMI-type carbapenemases. All 19 isolates were resistant to at least one carbapenem but susceptible to aminoglycosides, trimethoprim-sulfamethoxazole, tigecycline, and ciprofloxacin. Most isolates (17/19) gave positive results with the Carba-NP test for phenotypic carbapenemase detection...

Extending the class of group 6 metal-metal bonded methylate compounds supported by alkali metal counter-ions, the first sodium octamethylmolybdate(ii) complex [(TMEDA)Na]4Mo2Me8 and heptamethylchromate(ii) relations [(donor)Na]3Cr2Me7 (donor is TMEDA or TMCDA) are reported. The former was made by treating [(Et2O)Li]4Mo2Me8 with four equivalents of NaOtBu/TMEDA in ether; whereas the latter resulted from introducing TMEDA or TMCDA to ether solutions of octamethyldichromate [(Et2O)Na]4Cr2Me8. X-ray crystallography revealed [(TMEDA)Na]4Mo2Me8 is dimeric with square pyramidal Mo centres [including a short Mo-Mo interaction of 2...

The pathogenicity of Escherichia coli O78 strain K46, originally isolated from an outbreak of septicemia in neonatal lambs, was investigated in zebrafish embryo and murine models of infection. Its biofilm potential, cellulose production, and the expression of type 1 pili and curli fimbriae were measured by in vitro assays. The strain was highly pathogenic in the zebrafish embryo model of infection, where it killed all embryos within 24 h post inoculation (hpi) at doses as low as 1000 colony forming units. Zebrafish embryos inoculated with similar doses of commensal E...

Uropathogenic Escherichia coli (UPEC), the primary causative agent of urinary tract infections, colonize and invade the epithelial cells of the bladder urothelium. Infection of immature urothelial cells can result in the formation of persistent intracellular reservoirs that are refractory to antibiotic treatments. Previously, we defined a novel therapeutic strategy utilizing the bladder cell exfoliant chitosan to deplete UPEC reservoirs. However, though a single treatment of chitosan followed by ciprofloxacin administration had a marked effect on reducing UPEC titers within the bladder, this treatment failed to prevent relapsing bacteriuria...
