Assessing gut barrier integrity and reproductive performance following pre-mating oral administration of solid-lipid-nanoparticles designed for drug delivery.

Solid lipid nanoparticles (SLNs) have gained interest as drug delivery carriers due to their efficient cellular internalization and increased therapeutic effect of the loaded drug, with minimal side effects. Although recently several studies have shown the possibility to administer SLNs during pregnancy to vehicle mRNA to the placenta, data about the effect of premating exposure to SLNs on pregnancy outcome are scant. Considering that assumption of drug-delivering nanocarriers in reproductive age may potentially affect women's reproductive health, the aim of the present study was to evaluate whether repeated oral administration of SLNs to female mice prior to mating would influence key pregnancy outcomes.

Precise description of the interaction between molecular oxygen and metal surfaces is one of the most challenging topics in quantum chemistry. In this work, we use low-temperature scanning tunneling microscopy (STM) to identify and characterize an adsorption state of molecular oxygen that coordinates to three Ag atoms (μ) on Ag(100). Surprisingly, μ-O cannot be identified as a stable configuration with generalized gradient approximation (GGA)-level density functional theory (DFT) calculations.

Background: The rise in the frequency of liver cancer all over the world makes it a prominent area of research in the discovery of new drugs or repurposing of existing drugs.
Methods: This article describes the pharmacophore-based structure-activity relationship (3DQSAR) on the secondary metabolites of Alhagi maurorum to inhibit human liver cancer cell lines Hepatocellular carcinoma (HCC) and hepatoma G2 (HepG2) which represents the molecular level understanding for isolated phytochemicals of Alhagi maurorum. The definite features, such as hydrophobic regions, average shape, and active compounds' electrostatic patterns, were mapped to screen phytochemicals.
Synthesis, Anti-proliferation, Apoptosis Induction in Breast Cancer Cells, and Aromatase Inhibition of Coumarin-Triazole Hybrids: In Vitro and In Silico Studies.

Breast cancer is one of the most common cancers found in women worldwide. Besides the availability of clinical drugs, drug resistance and considerable side effects are concerning issues driven the needs for the discovery of novel anticancer agents. Aromatase inhibition is one of the effective strategies for management of hormone-dependent breast cancer.
View Article and Find Full Text PDFBackground: The contribution of MTHFR and TP53 genetic variants to breast carcinoma (BC) susceptibility has been examined, but their findings have been inconclusive. This work is designed to explore the potential roles of the MTHFR (rs1801131, rs1801133) and TP53 (rs1042522) variants with increased risk of BC using genetic and bioinformatic approaches.
Methods: This work included a total of 242 female participants [142 BCE patients and 100 healthy controls].
