[reaction: see text] Using a combination of chiral monodentate phosphoramidite ligands in the rhodium-catalyzed conjugate addition of boronic acids to three different substrates, we have shown for the first time that the ligand combination approach is applicable for C-C bond formation. Chiral catalysts based on hetero-combinations of ligands are found to be more effective than the homo-combinat...

Neutron diffraction with isotopic substitution (NDIS) experiments and molecular dynamics (MD) simulations have been used to characterize the structure of aqueous guanidinium carbonate (Gdm2CO3) solutions. The MD simulations found very strong hetero-ion pairing in Gdm2CO3 solution and were used to determine the best structural experiment to demonstrate this ion pairing. The NDIS experiments conf...

In social insects, workers trade personal reproduction for indirect fitness returns from helping their mother rear collateral kin. Colony membership is generally used as a proxy for kin discrimination, but the question remains whether recognition allows workers to discriminate between kin and nonkin regardless of colony affiliation. We investigated whether workers of the ant Formica fusca can i...

PURPOSE Stargardt disease 3 (STGD3) is a juvenile macular dystrophy caused by mutations in the elongase of very long-chain fatty acids-like 4 (ELOVL4) gene, which encodes an elongase involved in the production of extremely long-chain fatty acids. The STGD3-related mutations cause production of C-terminally truncated proteins (ELOVL4ΔC). STGD3 is transmitted in an autosomal dominant manner. To d...

Sterile-alpha-motif (SAM) domains are common protein interaction motifs observed in organisms as diverse as yeast and human. They play a role in protein homo- and hetero-interactions in processes ranging from signal transduction to RNA binding. In addition, mutations in SAM domain and SAM-mediated oligomers have been linked to several diseases. To date, the observation of heterogeneous SAM-medi...

A diversity-oriented solution and solid-phase synthesis of tetrahydroquinoline-based tricyclic derivatives has been achieved from enantiomerically pure, natural product-like bicyclic scaffold. The solution synthesis of enantiopure bicyclic scaffold was developed by asymmetric hetero Michael reaction. Our approach for the synthesis of polycyclic derivatives utilized regio- and stereoselective he...

Although highly controversial just a few years ago, the idea that G-protein-coupled receptors (GPCRs) may undergo homo-oligomerization or hetero-oligomerization has recently gained considerable attention. The recognition that GPCRs may exhibit either dimeric or oligomeric structures is based on a number of different biochemical and biophysical approaches. Although much effort has been spent to ...

We report on organometallic synthesis of luminescent (ZnSe/CdS)/CdS semiconductor heterostructured nanorods (hetero-NRs) that produce an efficient spatial separation of carriers along the main axis of the structure (type II carrier localization). Nanorods were fabricated using a seeded-type approach by nucleating the growth of 20-100 nm CdS extensions at [000 +/- 1] facets of wurtzite ZnSe/CdS ...

OBJECTIVE To analyze the degree of influence of the organizational identification on the experiences of pleasure and suffering of women who are members of the nursing staff of two general hospitals in Belo Horizonte. METHOD A quantitative study was conducted with 97 nurses and 414 nursing technicians chosen by convenience in their workplaces. We used a self-administered questionnaire containi...

Abstract We developed an electrocatalytic reduction of (hetero)aryl halides under mild conditions using a proton exchange membrane (PEM) reactor. This approach allows substituting the halogeno groups on aryl rings to protons by water and electron. Taking advantage this transformation, deuterodehalogenation halides, which forms mono‐deuterated (hetero)aryls, was demonstrated heavy as deuterium s...
