Microplastics in human urine: Characterisation using μFTIR and sampling challenges using healthy donors and endometriosis participants.

Microplastics (MPs) are found in all environments, within the human food chain, and have been recently detected in several human tissues. The objective herein was to undertake an analysis of MP contamination in human urine samples, from healthy individuals and participants with endometriosis, with respect to their presence, levels, and the characteristics of any particles identified. A total of 38 human urine samples and 15 procedural blanks were analysed.

Cytotoxic effects of Ridolfia segetum (L.) Moris phytoproducts in cancer cells.

Ethnopharmacological Relevance: The past few years have witnessed an increasing interest in essential oils (EOs) as potential therapeutic agents against a wide variety of pathologies, including cancer. EOs extracted from Ridolfia segetum (L.) Moris (R.

Secondary metabolites (essential oils) from sand-dune plants induce cytotoxic effects in cancer cells.

Ethnopharmacological Relevance: Despite advances in modern therapeutic strategies, cancer remains the second leading cause of death worldwide. Therefore, there is a constant need to develop more efficient anticancer targeting strategies. The anticancer therapeutic proprieties of medicinal plants and their bioactive compounds have been reported for several years, making natural extracts and/or compounds derived from these a promising source of novel anticancer agents.

WSB-1 regulates the metastatic potential of hormone receptor negative breast cancer.

Background: Metastatic spread is responsible for the majority of cancer-associated deaths. The tumour microenvironment, including hypoxia, is a major driver of metastasis. The aim of this study was to investigate the role of the E3 ligase WSB-1 in breast cancer biology in the context of the hypoxic tumour microenvironment, particularly regarding metastatic spread.

Low molecular weight heparin suppresses tissue factor-mediated cancer cell invasion and migration in vitro.

Elevated expression of tissue factor (TF) has been associated with an increased risk of thrombosis in the majority of cancers. Moreover, treatment of cancer patients with low molecular weight heparin (LMWH) appears to have beneficial effects that reach beyond controlling the immediate hypercoagulable state. In this study, we investigated the influence of the treatment of cancer cells with LMWH (0-2,000 μg/ml) on cell invasiveness and migration in cancer cell lines from five separate tissues; pancreatic, breast, colocarcinoma, ovarian and melanoma.
