GEM Operation in Negative Ion Drift Gas Mixtures

, 2003
The first operation of GEM gas gain elements in negative ion gas mixtures is reported. Gains up to several thousand were obtained from single-stage GEMs in carbon disulfide vapor at low pressure, and in mixtures of carbon disulfide with Argon and Helium,

Studies on Bile Pigments II. Seperation of Natural Direct Bilirubins [PDF]

, 1956
Separation of both forms of the direct bilirubin were carried out from the dog's gallbladder bile, and further isolations of them were also done. 1. The natural salt-form bilirubin was isolated after separation on the column of aluminium oxide with a n ...

Determination of clenbuterol with differential pulse anodic stripping voltammetry technique at tungsten disulfide-modified electrode

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2022
In the present work, tungsten disulfide was synthesised and characterised by using X-ray diffraction and scanning electron microscopy. This material was employed to modify a glassy-carbon electrode to analyse clenbuterol.

Introduction to protein folding for physicists [PDF]

, 2007
The prediction of the three-dimensional native structure of proteins from the knowledge of their amino acid sequence, known as the protein folding problem, is one of the most important yet unsolved issues of modern science.

Formation of protein cross-links by singlet oxygen-mediated disulfide oxidation

Redox Biology, 2021
Cross-links formed within and between proteins are a major cause of protein dysfunction, and are postulated to drive the accumulation of protein aggregates in some human pathologies. Cross-links can be formed from multiple residues and can be reversible (

Design of double-walled carbon nanotubes for biomedical applications [PDF]

, 2012
Double-walled carbon nanotubes (DWNTs) prepared by catalytic chemical vapour deposition were functionalized in such a way that they were optimally designed as a nano-vector for the delivery of small interfering RNA (siRNA), which is of great interest for

NMR solution structure of a chymotrypsin inhibitor from the Taiwan cobra Naja naja atra [PDF]

, 2013
The Taiwan cobra (Naja naja atra) chymotrypsin inhibitor (NACI) consists of 57 amino acids and is related to other Kunitz-type inhibitors such as bovine pancreatic trypsin inhibitor (BPTI) and Bungarus fasciatus fraction IX (BF9), another chymotrypsin ...

Development of catalyst-free carbon-sulfur bond formation reactions under aqueous media and their applications

Green Synthesis and Catalysis, 2022
Methods for the carbon-sulfur bond formation under catalyst-free, aqueous conditions are extremely useful in organic synthesis and chemical biology. Our laboratory has developed methodologies to construct carbon-thiol bonds, carbon-sulfinic acid bonds ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Solid-phase-assisted synthesis of targeting peptide-PEG-oligo(ethane amino)amides for receptor-mediated gene delivery. [PDF]

, 2012
In the forthcoming era of cancer gene therapy, efforts will be devoted to the development of new efficient and non-toxic gene delivery vectors. In this regard, the use of Fmoc/Boc-protected oligo(ethane amino)acids as building blocks for solid-phase ...
