The structure and morphology of nonmaterial formed by colloidal synthesis represent a subject of interest as it is a factor deciding the physicochemical properties and biological applications of nanostructures. Among various nanoparticles, gold can develop fractal assembled patterns. Herein, we report a nano-aggregate of a thiol-on-gold self-assembled structure and the influence of β-cyclodextr...

background & aim: parkinson's disease (pd) can be created with loss of dopaminergic substantial nigra neurons which is widely associated with oxidative stress and reduced glutathione (gsh), as the most important and abundant thiol in tissues and one of the antioxidant defense, is one of the earliest biochemical events related to parkinson's and consumption of antioxidants has a protec...

pegylation is a well-established technique utilized to overcome the problems related to the therapeutic applications of peptides and proteins. reasons for the pegylation of these biological macromolecules include reducing immunogenicity, proteolytic degradation and rapid clearance from blood circulation. octreotide is an octapeptide analogue of naturally-occurred somatostatin. this peptide has ...

in this study the effects of fe2o3 and fe3o4 magnetic nanoparticles and edta on urease activity was investigated. the effect of nano-fe2o3 and nano-fe3o4 on urease activity were investigated. urease activity was studies by uv-vis spectrophotometry at 40 °c at ph = 7.2 using sodium phosphate as buffer. measurements were carried out using 0.075 mg/ml of urease and a range of nano-fe2o3 and nano-f...

A thiol-epoxy click chemistry reaction is used to introduce thiol groups on magnetic nanogels for the attachment of Au nanorods.

Aim: Testicular torsion which is the most common cause of acute scrotum, a real surgical emergency. However, despite imaging techniques and laboratory studies used in differential diagnosis pathologies causing difficult. Therefore, there need for parameters that confirm testicular torsion.In our study, we aimed to investigate usability as parameter scrotum inflammation children via thiol-disulf...

Objective: We aimed to investigate the relationship between umblical coiling index and thiol/disulfide balance in SGA newborns compare with AGA newborns.
 Material Methods: Fetal umbilical cord serum samples were collected during labour homeostasis was measured. After birth, cords parameters examined including, length, number of coils, index.
 Results: Significant decrease native thio...

Objective: To determine serum thiol/disulfide homeostasis in panic disorder (PD). Methods: Serum native thiol, total thiol, and disulfide levels were measured in the patients with 40 PD patients and 40 healthy subjects. Serum native thiol, total thiol, and disulfide levels were measured with a novel colorimetric, automated method. The thiol-disulfide ratio was also calculated. Results: The nati...

background: parkinson's disease is one of the prevalent degenerative diseases of the neural system. oxidative stress, which has been recognized as the most important factor of parkinson's disease, plays a main role in the death of neurons in this disease. antioxidants have a proved role in the prevention of oxidative stress. objective: considering the presence of evidence regarding antioxidant ...
