Polymer films doped with 2-(5, 5-dimethyl-3-styryl-cyclohex-2-enylidene)-malononitrile chromophore and various sensitizers have been prepared and characterized. The material exhibits high sensitivity in the red region (S=0.26 cm(2)/J at lambda=633 nm), a large dynamic range (Dn=-0.05) , and large transient two-beam coupling gain (G=110 cm(-1)) . Self-diffraction effects, such as energy and phase coupling, and photoinduced scattering are studied.

A Novel Peptide Mapping Method Utilizing Cysteine as a Reducing Agent.
Pharm Res

Institute of Drug Metabolism and Pharmaceutical Analysis, College of Pharmaceutical Sciences, Zhejiang University, Hangzhou, 310058, China.
Purposes: In the peptide mapping reduction process for monoclonal antibodies (mAbs) and other proteins, the conventional reducing reagents β-mercaptoethanol (β-ME) and dithiothreitol (DTT) pose challenges due to their strong odor and toxicity at high concentrations. Cysteine (Cys), an essential amino acid for new protein synthesis, is an overlooked, nontoxic, and odorless reducing agent. This study presents a novel peptide mapping method using Cys as the reducing agent.

L-type amino acid transporter 1 (LAT1, SLC7A5), overexpressed in various cancers, mediates the uptake of essential amino acids crucial for tumor growth. It has emerged as a promising target for cancer therapy. Nanvuranlat (JPH203/KYT-0353), a LAT1 inhibitor, has shown antitumor activity in preclinical studies and efficacy in biliary tract cancer during clinical trials.

We report the fabrication and characterization of a Bi(III) oxide/polypyrrole (BiO/Ppy) nanocomposite thin film optoelectronic photodetector synthesized by a simple one-pot method. The nanocomposite consists of spherical BiO nanoparticles embedded in a Ppy matrix, forming a porous structure with a high surface area. The XRD analysis reveals that the BiO nanoparticles have a poly-crystalline nature with a crystal size of 40 nm and an optical bandgap of 2.

Despite their high clinical relevance, obtaining structural and biophysical data on transmembrane proteins has been hindered by challenges involved in their expression and extraction in a homogeneous, functionally-active form. The inherent enzymatic activity of receptor tyrosine kinases (RTKs) presents additional challenges. Oncogenic fusions of RTKs with heterologous partners represent a particularly difficult-to-express protein subtype due to their high flexibility, aggregation propensity and the lack of a known method for extraction within the native lipid environment.

The repercussions of hormone replacement therapy (HRT) and bisphosphonates pose serious clinical challenges and warrant novel therapies for osteoporosis in menopausal women. To confront this issue, the present research aimed to design and fabricate daidzein (DZ); a phytoestrogen-loaded hydroxyapatite nanoparticles to mimic and compensate for synthetic estrogens and biomineralization. Hypothesizing this bimodal approach, hydroxyapatite nanoparticles (HAPNPs) were synthesized using the chemical-precipitation method followed by drug loading (DZHAPNPs) via sorption.
