Background/aim: Thiol status is a good reflector of the cellular redox and have vital roles in various cellular signaling pathways. The purpose of the study was to investigate thiol status in patients with SARS-CoV-2 infection.
Materials And Methods: A total of 587 subjects (517 patients/70 healthy controls) were enrolled in the study.The patients were categorized into the groups regarding to the severity of disease (mild, moderate, severe, and critical).Thiol status of all groups were compared.
Results: The patients had significantly diminished thiol levels compared to controls. Thiol levels were gradually decreased as the severity of the disease increased. Logistic regression analyses identified that thiol concentrations were an independent risk factor for the disease severity in each phase (mild group OR 0.975, 95%CI 0.965-0.986; moderate group, OR 0.964, 95%CI 0.953-0.976; severe group OR 0.953, 95%CI 0.941-0.965; critical group OR 0.947, 95%CI 0.935-0.960).Thiol test exhibited the largest area under the curve at 0.949, with the highest sensitivity (98.6%) and specificity (80.4%).
Conclusions: Depleted thiol status was observed in SARS-CoV-2 infection. Decline of the thiol levels by degrees while the severity of infection increased was closely related to the progression of the disease. This outcome highlights that thiols could be an impressible biomarker for predicting of the severity of COVID-19.

Recent findings highlighted the potential of long non-coding RNAs (lncRNAs) as novel indicators of gestational diabetes mellitus (GDM), as they demonstrate altered expression in metabolic disorders, oxidative stress (OS) and inflammation (IFM). The aim of this study was to evaluate the diagnostic potential and prognostic significance of the OS/IFM-related lncRNAs H19, and in GDM and their correlations with redox status-related parameters. The relative quantification of selected lncRNAs from peripheral blood mononuclear cells (PBMCs) of GDM patients and controls (n = 50 each) was performed by qPCR.

Low molecular weight (LMW) thiols, particularly glutathione, play pathogenic roles in various multiorgan diseases. The liver is central for the production and systemic distribution of LMW thiols; thus, it is particularly susceptible to the imbalance of redox status that may determine increased oxidative stress and trigger the liver damage observed in metabolic dysfunction-associated steatotic liver disease (MASLD) models and humans. Indeed, increased LMW thiols at the cellular and extracellular levels may be associated with the severity of MASLD.

The amino thiols are key antioxidants in organisms, and their detection in food is of significant importance. This study developed a new stable isotope chemical labelling coupled with ultra-performance liquid chromatography-tandem mass spectrometry method to detect six amino thiols from fish samples. By the proposed method, amino thiols were labeled after liquid extraction using the stable isotope labeling reagents of iodoacetamide (IAM) and D-IAM.

The study aimed to compare the oxidative stress status in the kidney tissue of rats treated with paraquat and nanoparaquat. The levels of oxidative stress markers, including malondialdehyde (MDA), total antioxidant capacity (TAC), and thiol groups (TTG), were measured in the kidney tissue samples. A total of forty male Wistar rats were randomly assigned to eight groups, each consisting of five rats: a control group, a paraquat (PQ) group, an N-acetylcysteine (NAC) group, groups receiving nanoparaquat α and β (α and β), groups receiving PQ and NAC (PQ + NAC), and groups receiving nanoparaquat α and β with NAC (+ NACα and β).
