Novel multiphase composite electrode decorated with Pd nanoparticles for electrochemical determination of herbicides.

This study investigates the electrochemical determination of dicamba (3,6-dichloro-2-methoxybenzoic acid, DIC) and 2,4-D-dichlorophenoxyacetic acid (2,4-D) using a palladium (Pd)-decorated multiphase composite electrode (TiN/TiO/MgTiO/MgTiO) denoted as Pd@MPC. The synergistic coexistence and contact between these phases improved the electrochemical performance of the material and provided complementary properties such as electrical conductivity (from TiN and Pd), chemical stability (of MgTiO), and surface reactivity (of TiO and Pd), which are crucial for efficient electroanalytical applications. The electrode material was characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM), which confirmed the successful incorporation of Pd nanoparticles and significantly improved the catalytic properties.

Immunohistochemical Analysis of Placental Tissue of Women Infected with SARS-CoV-2 During Pregnancy-A Prospective Clinical Study.

SARS-CoV-2 has an affinity for binding to the human Angiotensin-converting enzyme 2 (ACE2) receptor through cleavage and conformational changes at the S1-S2 boundary and the receptor binding domain of the spike protein, which is also the most variable part of SARS-CoV-2. This study aimed to investigate the expression of Angiotensin-converting enzyme 2 (ACE2), spike protein, and CD68+ markers in placental tissue to demonstrate a possible correlation with the level of systemic oxidative stress biomarkers in patients who were infected with SARS-CoV-2 during pregnancy. A prospective clinical cohort study was designed to investigate the presence of CD68+ macrophages, ACE2, and spike proteins in placental tissue using immunohistochemical methods and to compare these results with oxidative stress from our previous study.

SARS-CoV-2 Infection and Its Association with Maternal and Fetal Redox Status and Outcomes: A Prospective Clinical Study.

The impact of the SARS-CoV-2 viral infection during pregnancy on the fetus can be direct-transmitted through the placenta-and indirect-creating unfavorable conditions for the development of the fetus because of inflammation, micro-thrombosis, and hypercoagulation. Our study aimed to determine the types and frequency of pathohistological changes in placental tissue in SARS-CoV-2-positive pregnant women and to examine the possible role of oxidative stress in the prognosis of the delivery and its maternal and fetal complications. This prospective clinical study included 50 pregnant women divided into two groups, SARS-CoV-2 positive (COVID-19 group) and SARS-CoV-2 negative (control group), from who we collected demographic, clinical, obstetric, biochemical and pathologic data.

Green Pre-Treatment Strategy Using Ionic Liquid-Based Aqueous Two-Phase Systems for Pesticide Determination in Strawberry Samples.

Pesticides used in agriculture can contaminate foods like fruits and vegetables, posing health risks to consumers and highlighting the need for effective residue monitoring. This study explores aqueous two-phase systems (ATPSs) comprising phosphonium or ammonium ionic liquids (ILs) combined with ammonium sulfate as an alternative pre-treatment method for extracting and concentrating the pesticides clomazone, pyraclostrobin, and deltamethrin from strawberry samples. Liquid-liquid equilibrium measurements for each ATPS were conducted, followed by extraction experiments to determine the most efficient systems for pesticide extraction.

Case report: Spontaneous rupture of leiomyosarcoma uteri 8 months after primary laparoscopic surgery of STUMP.

Introduction: Leiomyosarcoma (LMS), together with smooth muscle tumors of uncertain malignant potential (STUMP) and benign leiomyomas, belongs to a heterogeneous group of uterine neoplasms. According to the World Health Organization, tumors originating from uterine smooth muscle fibers are the second most frequent tumors. It is challenging to distinguish between STUMP and LMS because of an overlap of symptoms, lack of a precise definition, and unequivocal information obtained using imaging diagnostic methods.

Therefore, there is a need for the development of efficient and cost-effective methods for the separation and purification of these valuable compounds.

Five-year disease-free survival in FIGO IA stage endometrial cancer patients: Tertiary institution experience in a developing country.

Purpose: Endometrial cancer is characterized as histopathological, molecular, genetic, biological, and very diverse group of malignancies. Due to the need to precisely define the indications for adjuvant treatment in recent years, there has been a division made according to risk groups based on prognostic factors, which identify patients at risk for disease relapse, who may benefit from adjuvant therapy. The aim of this research was to examine the clinical and morphological factors that influence disease-free survival (DFS) and overall survival (OS) in patients with FIGO IA stage endometrial cancer.

Potential role of d--inositol in reducing oxidative stress in the blood of nonobese women with polycystic ovary syndrome.

d--Inositol (DCI), an isomer of inositol, possesses antioxidative and endothelial protective properties. Possibly due to a deficiency of insulin mediators, polycystic ovary syndrome (PCOS) is often associated with insulin resistance (IR) and hyperinsulinemia, likely responsible for an elevated production of reactive oxygen species. We investigated oxidative-related alterations of inositol in the blood of women with PCOS before and after treatment with DCI.
