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...

in this paper, synthesized (raw) multi-walled carbon nanotube (rmwcnts) surfaces were modified with chitosan and β-cyclodextrin using chen’s soft cutting technique. raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (tem). the results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...

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 ...

Aim. To investigate the role of a novel oxidative stress marker, thiol/disulphide homeostasis, in patients diagnosed with acute appendicitis (AA). Methods. In this study, seventy-one (43 male and 28 female) patients diagnosed with AA and 71 (30 male and 41 female) healthy volunteers were included. Age, gender, body mass index (BMI), haemoglobin (Hb), white blood cell (WBC), c-reactive protein (...

Gold nanoparticles (GNPs) are often used as colloidal carriers in numerous applications owing to their low-cost and size-controlled preparation as well as their straightforward surface functionalization with thiol containing molecules forming self-assembling monolayers (SAM). The quantification of the ligand density of such modified GNPs is technically challenging, yet of utmost importance for ...

in this paper, the chemical functionalization of carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. phosphorus ylides are important compound in organic chemistry. at first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...

This article provides an overview of the rich chemistry rhenium and manganese decacarbonyls, M2(CO)10 (M = Re, Mn) their acetonitrile derivatives [M2(CO)8(NCMe)2] as precursors for synthesis new di‒, tri‒ tetranuclear complexes derived from a wide range heterocyclic thiols such pyridine-2-thiol, pyrimidine-2-thiol, tetrahydropyrimidine-2-thiol, 2-mercapto-1-methylimidazole, benzimidazole-2-thio...

Mercury thrown even at low concentrations in water resources causes a severe threat to the ecosystem hence presented work describes low-cost and environmentally friendly clean-up platform for decontamination of terms mercury ions. For this purpose, MgFe2O4—Gum Arabic composite was prepared with simple ultrasound-assisted precipitation route further modified l-Cysteine as thiol resource improve ...

In this study, attention and memory functions were evaluated during two types of TMT: the ordinary random pattern (TMT-random), and the test which eventually revealed the figure (TMT-figure). Using fMRI, the areas significantly activated by the TMT-figure compared with TMT-random were BA18, BA13, BA6 (attention-related), and hippocampus (memory-related). The TMT-figure may be more suitable for ...
