The dehydrogenation of primary and secondary amine-boranes (RNH(2)·BH(3) and R(2)NH·BH(3); R = alkyl groups) was studied using the bulky N-heterocyclic carbene IPr (IPr = [(HCNDipp)C:]; Dipp = 2,6-(i)Pr(2)C(6)H(3)) as a stoichiometric dehydrogenation agent. In the case of primary amine-boranes, carbene-bound adducts IPr·BH(2)-NH(R)-BH(3) were obtained in place of the desired polymers ...

In human mate choice, sexually dimorphic faces and voices comprise hormone-mediated cues that purportedly develop as an indicator of mate quality or the ability to compete with same-sex rivals. If preferences for faces communicate the same biologically relevant information as do voices, then ratings of these cues should correlate. Sixty ...

An electrochemical synthesis is developed through quantitative electrochemical reaction of N-alkylcarbazole leading to a novel class of structurally interconnected high-C(60) content (60 wt%) polymer films with negligible doping and intrinsic physicochemical properties of pure C(60) . This strategy allows preparation of previously unavailable low-doped fullerene-containing non-conjugated polymers and broadens the ...

Monolayers of polymer-encapsulated Au nanoparticles with controlled density are obtained via a facile solution-based method by modulating the inter-particle repulsion and using empty polymer micelles as spacers. These Au nanoparticles are then used to catalyze the vapor transport growth of metal oxide nanowires, where distinct density-dependent growth regimes are identified.

Hatching of infective larvae from embryonated eggs in the intestine is an essential first step in Trichuris infections. There are three isolates of the murine parasitic nematode Trichuris muris: E, E-J (the E isolate maintained in Japan), and S. Incubation of T. muris embryonated eggs with the intestinal bacteria Escherichia ...

Diffusion tensor imaging (DTI) studies consistently reported abnormalities in fractional anisotropy (FA) and radial diffusivity (RD), measures of the integrity of white matter (WM), in bipolar disorder (BD), that may reflect underlying pathophysiologic processes. There is, however, a pressing need to identify peripheral measures that are related to these WM ...

Whole-genome duplication (WGD) has been recurring and single-gene duplication is also widespread in angiosperms. Recent whole-genome DNA methylation maps indicate that gene body methylation (i.e. of coding regions) has a functional role. However, whether gene body methylation is related to gene origins and duplication modes has yet to be reported. ...

This study examined to what extent individual mate selectivity could be explained by characteristics of the mating market. Specifically, we hypothesized that females' selectivity would be more malleable, or context-dependent, than males' mate selectivity (cf. Baumeister, 2000; Gangestad & Simpson, 2000). In a series of 22 speed-dating events in which ...

The origin of the pygmy right whale (Caperea marginata) has long been one of the most vexing conundrums of marine mammal evolution. The extremely disparate skeletal structure of Caperea and a patchy fossil record have left morphology and molecules at odds: whereas most morphological analyses ally Caperea with right whales ...

Adherence to antiretroviral therapy is an important predictor of long-term treatment success. Adherence can be differentiated between early adherence challenges, that are about integrating pill-taking into daily life, and long-term adherence, where patients struggle to maintain clinical connections and interrupt clinical care and medication use. In resource-limited settings, treatment interruptions ...

Glomerular filtration rate (GFR) is an essential clinical assessment of renal function post-renal transplantation. Creatinine clearance (CrCl) measured over 12 h and estimated GFR (e-GFR) (calculated by the Modification of Diet in Renal Disease equation) were compared in 28 stable renal transplant recipients (RTRs). This single center study included 14 African ...

In 2009 Pertab, James, and Bigler published a critique of two prior meta-analyses by Binder, Rohling, and Larrabee (1997) and Frencham, Fox, and Maybery (2005) that showed small effect size difference at least 3 months post-injury in individuals who had sustained a mild traumatic brain injury (mTBI). The Binder et al. ...

Soil and plant hydraulics constrain ecosystem productivity by setting physical limits to water transport and hence carbon uptake by leaves. While more negative xylem water potentials provide a larger driving force for water transport, they also cause cavitation that limits hydraulic conductivity. An optimum balance between driving force and cavitation ...

The aridification from Middle Miocene onwards has transformed the Asian interior into an arid environment, and the Pleistocene glacial-interglacial oscillations exerted further ecological impact. Therefore, both aridification and glaciation would have considerably influenced the evolution of many mid-latitude species in temperate Asia. Here, we tested this perspective by a phylogeographic ...
