Assessment of toxicity and oxidative stress induced by rare earth oxide nanoparticles in brine shrimp (Artemia salina).

This study meticulously explored the oxidative stress effects induced by lanthanum (III) oxide (LaO), erbium (III) oxide (ErO), and yttrium (III) oxide (YO) nanoparticles on Artemia salina, with the objective of evaluating the environmental toxicity of rare earth oxide nanoparticles. The characterization of the nanoparticles was conducted using a suite of advanced techniques, including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), dynamic light scattering (DLS), and zeta potential analysis. Artemia salina, a widely recognized model organism in ecotoxicological research, was exposed to these nanoparticles under meticulously controlled laboratory conditions.

Women's preferences and experiences of birthing practices in Turkey: A cross-sectional study.

In this study, the aim was to evaluate the preferences and experiences interventions among women in Turkey. A total of 347 women who gave birth vaginally participated in this analytical cross-sectional study. Data were collected using the face-to-face interview technique in the clinic rooms within the first 24 hours after delivery, when the women's babies were asleep, allowing the mothers to comfortably answer the questions before discharge.

Investigation of factors affecting mothers' satisfaction with childbirth and the supportive care given to them during labor.

The aim of this study was to investigate the factors affecting mothers' satisfaction with birth and the supportive care given to them during labor. The tools used to collect the data were the Scale for Measuring Maternal Satisfaction in Birth and Bryanton Adaptation of the Nursing Support in Labor Questionnaire. The study sample consisted of 352 mothers.

Factors Affecting Breastfeeding in Births Given During the Day and at Night; A Cross-Sectional Comparative Study.

How giving birth at night and during the day affects the breastfeeding process should be evaluated when health services are planned. In this study, we investigated the effect of giving birth at night and during the day on the breastfeeding process. In this cross-sectional comparative study, we included 228 women who gave birth at night and 192 women who gave birth during the day.

Green Synthesis (Paeonia kesrouanensis) of Silver Nanoparticles and Toxicity Studies in Artemia salina.

This study aims to describe a simple and environmentally friendly procedure for producing silver nanoparticles (AgNPs) using Paeonia kesrouanensis (P. kesrouanensis) extracts and to determine the toxic effect in the aquatic environment. The morphologies, size, size distributions, and structural properties were analyzed using SEM-EDX, TEM, DLS, zeta potential, FTIR, and XRD.

An Evaluation Research About Effects of Characterized Cadmium Selenide (CdSe) and Lead Selenide (PbSe) Quantum Dots on Brine Shrimp (Artemia salina).

Quantum dots (QDs), such as cadmium selenide (CdSe) and lead selenide (PbSe) exhibit excellent optical, magnetic and chemical properties due to their extremely size (ca. 1-10 nm) and are attractive semiconductor nanomaterials for optical studies and energy storage. In this study, aqueous synthesis of CdSe and PbSe QDs in a size range of 2-10 nm was described.

Effects of Zn and ZnO Nanoparticles on Artemia salina and Daphnia magna Organisms: Toxicity, Accumulation and Elimination.

In the study, Zn in the size of 40-60 nm and 80-100 nm and ZnO in the size of 10-30 nm were applied to A. salina and D. magna individuals in 7 groups with 3 repetitions.

Assessment of Oxidative Stress on Artemia salina and Daphnia magna After Exposure to Zn and ZnO Nanoparticles.

In this study, the effect of zinc nanoparticles (Zn NPs) and zinc oxide nanoparticles (ZnO NPs) on Artemia salina and Daphnia magna, the primary consumer organisms were investigated. In this sense, investigation of trophic transfer and ecological sustainability potentials among living things, such as fish and crustaceans that are at the top of the food chain were also aimed. Zn NPs in the size of 40-60 nm and 80-100 nm and ZnO NPs (10-30 nm) were administered to A.

Assessment of impact of α-Fe O and γ-Fe O nanoparticles on phytoplankton species Selenastrum capricornutum and Nannochloropsis oculata.

In this study, the impact of alpha-iron oxide (α-Fe O , 20-40 nm) and gamma iron oxide (γ-Fe O , 20-40 nm) nanoparticles (NPs) on phytoplankton species Selenastrum capricornutum and Nannochloropsis oculata was investigated Characterizations of the NPs were systematically carried out by TEM, dynamic light scattering, zeta potential, X-ray diffraction, SEM, and Fourier transformation infrared spectroscopy. Acute toxicity was tested between 0.2 and 50 mg/L for each NP for a period of 72 hours exposure.
