QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study

Advanced Science, EarlyView.
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

Angewandte Chemie, EarlyView.
Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

Determinação do nível de lisina na fase inicial-I do crescimento de suínos, através da composição química e deposição de tecidos

Boletim de Indústria Animal, 2013
Vinte leitões híbridos comerciais, machos castrados e fêmeas foram amostrados em um experimento de desempenho e abatidos para determinar o melhor nível de lisina sobre a composição química das frações corporais e taxas de deposição protéica e lipídica na carcaça e corpo vazio. Os níveis de lisina total foram 0,85; 0,95; 1,05; 1,15 e 1,25%

Structural Insights Into Man9 Recognition by the HIV Antibody 2G12 Revealed by Paramagnetic NMR

Advanced Science, EarlyView.
The HIV gp120 glycoprotein displays Man9 oligomannose structures that are recognized by the neutralizing antibody 2G12. Detailed characterization of the binding epitope in solution is important for immunogen design but remains challenging, since the signals of the terminal mannoses from the three arms of Man9 (D1, D2, and D3) cannot be distinguished in
