Global occurrence and hazards of benzodiazepines in water resources: Knowledge gaps and future directions.

Benzodiazepines (BZDs) are a group of psychoactive pharmaceuticals that are used to treat a variety of medical conditions. Due to the widespread usage of this class of medicines, BZDs have been frequently reported in aquatic systems. We performed a critical review of the refereed literature to better understand the prevalence of BZDs in aquatic matrices and associated water quality hazards.

Inhibition of Fin Regeneration in Fathead Minnow () by a Potent Synthetic Glucocorticoid and Development of Adverse Outcome Pathway 334.

Despite structural and functional conservation across vertebrate species, the glucocorticoid receptor has been minimally studied in comparison to other biological targets for endocrine-disrupting compounds in aquatic systems. Because prolonged use of pharmaceutical glucocorticoids in humans has been linked to osteoporosis and impaired bone growth, we hypothesized that the ability of teleost fish to regenerate fins following damage may be inhibited by exposure to synthetic glucocorticoids in the environment. In the present study, we examined fin regeneration following a 7 days waterborne exposure of juvenile fathead minnows () to the synthetic glucocorticoids, fluticasone propionate and dexamethasone.

Associations between exposure to sodium/iodide symporter inhibitors and markers of thyroid function: A systematic review and meta-analysis.

Background: Perchlorate, nitrate, and thiocyanate are well-known sodium/iodide symporter (NIS) inhibitors that disturb iodide uptake at the thyroid, affecting thyroid function. However, the associations between NIS inhibitor exposure and thyroid function are not well summarized in humans.

Objective: We aimed to summarize associations between NIS inhibitor exposure and thyroid function markers and to identify key information gaps for future studies.

A novel approach for unveiling co-occurrence patterns of UV filter mixtures in sunscreens: Prioritization for hazard and risk assessment.

In recent years, concerns regarding the toxicity of organic UV filters in sunscreen products have increased. While sunscreen products contain multiple UV filters in combination, current understanding on their co-occurrence patterns and mixture toxicities is still limited. This study utilized a public database, "Hwahae", and analyzed 2183 sunscreen products marketed in South Korea as of 2019, using an association rule mining (ARM) to elucidate their co-occurrence patterns.

Exposure to Phthalates and Alternative Plasticizers in Patients with Impaired Kidney Function in Korea: Temporal Trend during 2011-2020 and Its Association with Chronic Kidney Disease.

Phthalates are chemical risk factors of chronic kidney disease (CKD); however, little is known about temporal trends of phthalate exposure and associated health risks among CKD patients. Such information is even scarce for alternative plasticizers. CKD patients were recruited from 2011 to 2020 in Korea ( = 200) and assessed for the temporal changes of both traditional and alternative plasticizer exposure.

Thyroid, neurodevelopmental, and kidney toxicities of common organic UV filters in embryo-larval zebrafish (Danio rerio), and their potential links.

Organic UV filters (OUVFs) have been commonly used in sunscreen and many consumer products. Following dermal application, these compounds can enter circulation and may cause systemic effects in humans. In the present study, we chose four OUVFs frequently detected in the environment, i.

Deciphering Host-Parasite Interplay in Infection through a One Health View of Proteomics Studies on Drug Resistance.

Recent efforts in the study of vector-borne parasitic diseases (VBPDs) have emphasized an increased consideration for preventing drug resistance and promoting the environmental safety of drugs, from the beginning of the drug discovery pipeline. The intensive use of the few available antileishmanial drugs has led to the spreading of hyper-resistant strains, resulting in a chronic burden of the disease. In the present work, we have investigated the biochemical mechanisms of resistance to antimonials, paromomycin, and miltefosine in three drug-resistant parasitic strains from human clinical isolates, using a whole-cell mass spectrometry proteomics approach.

Adverse thyroid hormone and behavioral alterations induced by three frequently used synthetic musk compounds in embryo-larval zebrafish (Danio rerio).

Synthetic musk compounds (SMCs) have been extensively used in numerous consumer products, such as perfumes, cosmetics, soap, and fabric softener. Due to their bioaccumulative nature, these compounds have often been detected in the aquatic ecosystem. However, their effects on endocrine and behavioral effects in freshwater fish have rarely been investigated.

Effects of 2-ethylhexyl-4-methoxycinnamate (EHMC) on thyroid hormones and genes associated with thyroid, neurotoxic, and nephrotoxic responses in adult and larval zebrafish (Danio rerio).

One of the most widely used UV filters, 2-ethylhexyl-4-methoxycinnamate (EHMC), has been widely detected in the environment. While its endocrine disruption potential has often been reported, toxicological information on EHMC is limited. This study was conducted to determine the thyroid, neurological and renal toxicity potentials of EHMC in adult male and embryo-larval zebrafish (Danio rerio).
