Assessment of oxidative stress and trace element dynamics in acute myocardial infarction and heart failure: a focus on zinc, copper, and thiol dynamics.

Background: Acute Myocardial Infarction (AMI) and Heart Failure (HF) are the leading global causes of death from Cardiovascular Diseases (CVD). This study aimed to investigate the association of serum Zinc (Zn), Copper (Cu), and thiol levels with CVD and new potential biomarkers.

Methods: The study included serum samples from 150 participants, including 50 AMI patients, 50 HF patients, and 50 healthy individuals.

Mass Spectrometry-Based Untargeted Metabolomics Identifies Distinct Metabolic Signatures in Infertility: A Comparative Analysis of PCOS, POR, and NOR.

Background: Infertility affects approximately 15% of reproductive-age couples, with polycystic ovary syndrome and poor ovarian reserve being major contributing factors. Metabolomic profiling of follicular fluid offers insights into the underlying metabolic disturbances associated with these infertility phenotypes. This study aims to identify metabolic biomarkers distinguishing PCOS, POR, and male factor infertility, which may facilitate improved diagnostic and therapeutic strategies.

Serum NMR metabolomics in distinct subtypes of hematologic malignancies.

Hematologic malignancies encompass a diverse array of subtypes, contributing to substantial heterogeneity that poses challenges in predicting clinical outcomes. Leveraging the capabilities of nuclear magnetic resonance holds substantial promise in the detection of serum biomarkers and individual metabolic alterations in patients. This study involved the analysis of the sera from patients with acute myeloid leukemia, chronic lymphocytic leukemia, and non-Hodgkin lymphoma to investigate the affected metabolites and their associated pathways.

Short-term effects of dapagliflozin on biomarkers of bone and mineral metabolism in patients with diabetic kidney disease: A prospective observational study.

Background: There is still a lack of information regarding the impact of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on bone and mineral metabolism in patients with diabetes and chronic kidney disease (CKD). Therefore, we aimed to investigate the effects of SGLT2i in a cohort of patients suffering from diabetic kidney disease (DKD).

Methods: In this prospective observational study, patients with type 2 diabetes and biopsy-proven diabetic nephropathy or presumptive DKD with eGFR levels ≥20 ml/min/1.

Mass spectrometry-based untargeted metabolomics study of non-obese individuals with non-alcoholic fatty liver disease.

Objectives: Non-alcoholic fatty liver disease (NAFLD) is a disease characterized by the accumulation of excessive fat in the liver, which can lead to fibrosis and has an increasing prevalence. NAFLD requires non-invasive diagnostic biomarkers. While typically observed in overweight individuals, it can also occur in non-obese/non-overweight individuals.

Measurement of vitamin K and its derivatives in human plasma through enzyme-assisted liquid chromatography-tandem mass spectrometry assay.

Vitamin K is an essential lipophilic vitamin that acts as a coenzyme in several metabolic pathways. Accurate measurement of apolar metabolites transported by lipoproteins in serum matrices requires high-recovery extractions of vitamin K and its derivatives following standardized protocols. Conventionally developed methods in this field have predominantly employed solid-phase extraction for the measurement of vitamin K and its derivatives.

Investigation of serum enzyme activities and oxidative stress markers in preeclampsia: a multiparameter analysis.

Objectives: Preeclampsia, a high cause of fetomaternal morbidity-mortality, remains a significant burden affecting 8% of all pregnancies. Environmental conditions induce disease development leading to endothelial dysfunction in genetically predisposed women. Our aim is to discuss oxidative stress as a well-established contributing factor to disease progression with being the first study to show new evidence about serum dehydrogenase enzyme levels (isocitrate, malate, glutamate dehydrogenase) with oxidative markers (myeloperoxidase, total antioxidant-oxidant status, oxidative stress index).

Maternal Serum Levels of Zinc, Copper, and Thiols in Preeclampsia Patients: a Case-Control Study.

Preeclampsia is one of the leading causes of maternal mortality-morbidity, and environmental factors act as the main driving force for the development of disease in genetically lean women. Trace element levels (zinc, copper) and thiol state (total, native thiol) may affect involved risk factors and play a role in the pathogenesis. The objective of our study is to assess trace element and thiol levels in patient and control groups.

Effect of Camellia sinensis, Hypericum perforatum and Urtica dioica on kidney and liver injury induced by carbon tetrachloride in rats.

This study is aimed to investigate the effects of Camellia sinensis (CS), Hypericum perforatum (HP) and Urtica dioica (UD) in kidney and liver injury induced by carbon tetrachloride (CCl4) in rats. Highly toxic CCl4 which is used as a solvent in industry comprises experimental toxicity in rats and is widely used in hepatotoxicity and other tissue injury models. The purpose of this investigation is to monitor blood and various tissues by biochemical and histopathological analysis for preventive effects of CS, HP and UD on oxidative stress induced by administration of CCl4 and to enlighten the probable mechanism.

Effects of intra-articular administration of autologous bone marrow aspirate on healing of full-thickness meniscal tear: an experimental study on sheep.

Objective: The aim of this study was to evaluate the effects of bone marrow-derived mesenchymal stem cell and bone marrow elements on the healing of meniscal tears.

Methods: This study was performed on twelve, 2-year-old male Tahirova sheep. In each subject, one knee was used for experiment purposes and the other knee was used as a control.
