Controlled Synthesis of Silver Nanoparticles Using Double Reductants and Its Voltammetric Characteristics Study [PDF]

open access: yes, 2016
Constructing robust silver nanoparticles (AgNPs) with good shape and dispersibility is of particular interest in analytical applications. Herein, monodispersibility AgNPs with the average size of 20 nm have been successfully prepared via one-pot method ...

The specificity of cysteamine oxygenase

open access: yesFEBS Letters, 1975
Oxidation of cysteamine to hypotaurine is catalyzed by cysteamine oxygenase (EC 1.13.11.19), a non-heme iron enzyme of large distribution [l-3] . A similar oxidation of cysteine to cysteine sulfinic acid has been reported to require a different oxygenase [4,.5]. Specificity of cysteamine oxygenase has been studied earlier in this laboratory by assaying

Copper-cysteamine and methods of use [PDF]

open access: yes, 2017
Structure and luminescence properties of a new Cu-Cyteamine (Cu-Cy) crystal material are provided. The crystal structure of the Cu-Cy is determined by single crystal X-ray diffraction.

Beneficial effects of cysteamine in Thy1-α-Syn mice and induced pluripotent stem cells with a SNCA gene triplication

open access: yesNeurobiology of Disease, 2020
A number of publications have reported that cysteamine has significant therapeutic effects on several aspects of Parkinson's disease (PD)-related pathology but none of these studies have evaluated its impact on pathological forms of α-Synuclein (α-Syn ...

Synthesis of diacylated γ-glutamyl-cysteamine prodrugs, and in vitro evaluation of their cytotoxicity and intracellular delivery of cysteamine [PDF]

open access: yes, 2015
To overcome the major disadvantages of cysteamine, the only registered treatment for the rare genetic disease cystinosis, nine prodrugs of γ-glutamyl-cysteamine (4) were synthesized for evaluation.

Evaluation of the effect of adding cysteamine on Ros 308 sperm quality parameters and reduction of lipid peroxidation rate during freezing-thawing process [PDF]

open access: yesپژوهش های علوم دامی, 2022
Introduction: Long-term storage of semen is essential for achieving the benefits of artificial insemination (Tuncer et al. 2010). This is carried out by sperm cryopreservation, which stops the sperm metabolic activities, allowing long storage (Bailey et ...

Facile synthesis of cooperative acid-base catalysts by clicking cysteine and cysteamine on an ethylene-bridged periodic mesoporous organosilica [PDF]

open access: yes, 2016
A periodic mesoporous organosilica (PMO) that contains ethylene bridges was functionalized to obtain a series of cooperative acid-base catalysts. A straightforward, single-step procedure was devised to immobilize cysteine and cysteamine on the support ...

Glutathione amperometric detection based on a thiol-disulfide exchange reaction [PDF]

open access: yes, 2006
A method based on a thiol-disulfide exchange reaction is proposed for glutathione detection. The method utilises a reaction between glutathione and an excess of the disulfide cystamine which produces an equimolar concentration of the thiol cysteamine ...
