Adsorption and Thermal Decomposition of Triphenyl Bismuth on Silicon (001).

We investigate the adsorption and thermal decomposition of triphenyl bismuth (TPB) on the silicon (001) surface using atomic-resolution scanning tunneling microscopy, synchrotron-based X-ray photoelectron spectroscopy, and density functional theory calculations. Our results show that the adsorption of TPB at room temperature creates both bismuth-silicon and phenyl-silicon bonds. Annealing above room temperature leads to increased chemical interactions between the phenyl groups and the silicon surface, followed by phenyl detachment and bismuth subsurface migration.

Selection Criteria for Small-Molecule Inhibitors in Area-Selective Atomic Layer Deposition: Fundamental Surface Chemistry Considerations.

ConspectusAtomically precise and highly selective surface reactions are required for advancing microelectronics fabrication. Advanced atomic processing approaches make use of small molecule inhibitors (SMI) to enable selectivity between growth and nongrowth surfaces. The selectivity between growth and nongrowth substrates is eventually lost for any known combinations, because of defects, new defect formation, and simply because of a Boltzmann distribution of molecular reactivities on surfaces.

Tetranectin as a potential novel prognostic biomarker in anthracycline-related cardiac dysfunction.

To assess the association of serum tetranectin levels with cardiac remodeling parameters and to evaluate its prognostic role in women with anthracycline-related cardiac dysfunction (ARCD) and without previous cardiovascular diseases (CVD) during 24-month follow-up period. A total of 362 women with primary diagnosed breast cancer who were planned to be treated with anthracyclines were examined. At 12 months after chemotherapy completion, all women were examined and ARCD was diagnosed in 114 patients.

[Anthra-cycline-Induced Cardiotoxicity: the Role of Genetic Predictors].

Aim      To evaluate the predictive significance of gene polymorphism in endothelin-1 type 2A receptor, NADPH oxidase, p53 protein, endothelial nitric oxide synthase, caspase 8, interleukin-1β, tumor necrosis factor-α, superoxide dismutase-2, glutathione peroxidase-1, β1-adrenoceptor, angiotensin-converting enzyme, and matrix metalloproteinase-3 (MMP-3) genes in evaluating the risk of anthracycline-induced cardiotoxicity (AIC) in women without concurrent cardiovascular diseases (CVD).Material and methods  This study included 176 women aged 45.0 [42.

"Stapling" scFv for multispecific biotherapeutics of superior properties.

Single-chain fragment variable (scFv) domains play an important role in antibody-based therapeutic modalities, such as bispecifics, multispecifics and chimeric antigen receptor T cells or natural killer cells. However, scFv domains exhibit lower stability and increased risk of aggregation due to transient dissociation ("breathing") and inter-molecular reassociation of the two domains (VL and VH). We designed a novel strategy, referred to as stapling, that introduces two disulfide bonds between the scFv linker and the two variable domains to minimize scFv breathing.
