As engineered nanoparticles (NPs) are increasingly used, their entry into the environment has become an important topic for water sustainability. Recent investigations point to the critical role of natural organic matter (NOM) in altering the persistence of NPs by complexing with their surfaces. The NP-NOM complex, in turn, is the ...

Non-Abelian topological superconductors are characterized by the existence of zero-energy Majorana fermions bound in the quantized vortices. This is a consequence of the nontrivial bulk topology characterized by an odd Chern number. It is found that in topological semimetals with a single two-band crossing point all the gapped superconductors are ...

The polyethylenimine (PEI) derivatives (PTn) are prepared by treating PEI25k with Tris(hydroxymethyl) acrylamidomethane via the Michael addition. These PTns can effectively condense nucleic acids into nanosized particles with positive surface charges. The PTns show lower cytotoxicity and better serum-resistant capacity than PEI25k. Specially, the transfection efficiency of PT26/DNA is 29-fold ...

Stigmasterol and sitosterol, important sterols present in plants, are known to influence permeability and fluidity characteristics of the plasma membrane and other organellar membranes. We had previously demonstrated that the Arabidopsis Atcyp710A1 gene, which catalyzes conversion of sitosterol into stigmasterol, plays a role in plasma membrane permeability, thus influencing leakage ...

Sensory substitution is a promising technique for mitigating the loss of a sensory modality. Sensory substitution devices (SSDs) work by converting information from the impaired sense (e.g., vision) into another, intact sense (e.g., audition). However, there are a potentially infinite number of ways of converting images into sounds, and it ...

Arabidopsis thaliana lines expressing only one cruciferin subunit type (double-knockout; CRUAbc, CRUaBc, or CRUabC) or devoid of cruciferin (triple-knockout; CRU-) or napin (napin-RNAi) were generated using combined T-DNA insertions or RNA interference approaches. Seeds of double knockout lines accumulated homohexameric cruciferin and contained similar protein levels as the wild type ...

Two concise and high-yielding diastereoselective syntheses of 4-aryl-3-methyl-4-piperidinemethanols were realized from 1,3-dimethyl-4-piperidinone. The key reactions to control the C3-C4 relative stereochemistry were the alkoxymethylation of a metalloenamine generated from 4-aryl-3-methyl-1,2,3,6-tetrahydropyridine that afforded the (3R*,4S*)-form, and the nucleophilic substitution of a fluoroarene with deprotonated 3-methyl-4-piperidinenitrile giving the (3R*,4R*)-isomer. The corresponding fluoromethyl ...

Rationale: Studies identify common factors important for a "good death." However, it is important for clinicians to individualize end-of-life care by eliciting patients' preferences. We sought to determine preferences for death and dying among veterans with chronic obstructive pulmonary disease (COPD) by performing a cross-sectional study. Participants (n = 376) ...

BACKGROUND: Studies have consistently shown that Latinos with depression have lower adherence to antidepressant medication. Given that low adherence is associated with poorer response to treatment, this is a likely source of unequal care. The current study examined the efficacy of a motivational interviewing intervention for improving antidepressant adherence among ...

Although high-temperature superconductor cuprates have been discovered for more than 25 years, superconductors for high-field application are still based on low-temperature superconductors, such as Nb(3)Sn. The high anisotropies, brittle textures and high manufacturing costs limit the applicability of the cuprates. Here we demonstrate that the iron superconductors, without most of ...

Risk stratification after pregnancy with GDM is based on screening with the 2h-OGTT. Actually, prediabetes and diabetes are diagnosed by impaired fasting (FPG) and 120'-post load glucose levels (120'-PLG). We hypothesized that the clinical information could be improved by including measurements at different time points from the OGTT in the ...
