Detection of an Extrasolar Planet Atmosphere [PDF]

Astrophys.J.568:377-384,2002, 2001
We report high precision spectrophotometric observations of four planetary transits of HD 209458, in the region of the sodium resonance doublet at 589.3 nm. We find that the photometric dimming during transit in a bandpass centered on the sodium feature is deeper by (2.32 +/- 0.57) x 10^{-4} relative to simultaneous observations of the transit in ...

Synthesis of 1,2,3-triazole functionalized hyperbranched poly(ethyleneimine) and its use as multifunctional anionic macroinitiator for diglycidyl ether of bisphenol A curing [PDF]

, 2016
Hyperbranched poly(ethyleneimine) (PEI) has been modified by the addition of propargyl acrylate following a Michael addition reaction. On this polymer (PEI-yne) a copper (I)-catalyzed azide alkyne cycloaddition (CuAAC) has been performed to obtain a ...

Effects of Sodium Azide, Barium Ion, d-Amphetamine and Procaine on Inward Rectifying Potassium Channel 6.2 Expressed in Xenopus Oocytes

Journal of the Formosan Medical Association, 2008
Background/Purpose: Inward rectifying potassium channel 6.2 (Kir6.2 Δ C26 channel) is closely related to ATP-sensitive potassium channels. Whether sodium azide, barium ion, d-amphetamine or procaine acts directly on the Kir6.2 Δ C26 channel remains ...

Cross-Correlated Motions in Azidolysozyme [PDF]

arXiv, 2021
The changes in the local and global dynamics of azide-labelled Lysozyme compared with that of the wild type protein are quantitatively assessed for all alanine residues along the polypeptide chain. Although attaching -N$_3$ to alanine residues has been considered to be a minimally invasive change in the protein it is found that depending on the ...

Release of macromolecules from albumin-heparin microspheres [PDF]

, 1992
Hydrophilic microspheres based on albumin-heparin conjugates have been prepared as a macromolecular delivery system. The soluble albumin-heparin conjugate was synthesized and crosslinked in a water-in-oil emulsion with glutaraldehyde to form microspheres

High‐Throughput Microfluidic‐Mediated Assembly of Layer‐By‐Layer Nanoparticles

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

3D Bioprinted Coaxial Testis Model Using Human Induced Pluripotent Stem Cells:A Step Toward Bicompartmental Cytoarchitecture and Functionalization

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
The ability of human induced pluripotent stem cells (hiPSCs) to model developmental processes makes them a promising source for engineering testicular tissues to study in vitro maturation and sperm production. This work describes the first hiPSC‐derived testicular model and shows that it captures functional aspects of prepubertal testicular tissues ...

Author Correction: Next generation histology methods for three-dimensional imaging of fresh and archival human brain tissues

Nature Communications, 2018
In the original version of this Article, the concentration of boric acid buffer for the SDS clearing solution was given incorrectly as ‘1 M sodium borate’ and should have read ‘0.2 M boric acid’.
