The aim of this study was to investigate the uptake of four beta-blockers by the model plant Lepidium sativum (garden cress) and their possible metabolization over a time period of 8 days. Therefore, cress was grown hydroponically in tap water for a week until they were matured, following irrigation with drug-containing water over the course of another 8 days. Samples were taken at days 1, 2, 4, and 8 after irrigation started. All four beta-blockers were taken up by the plants and the different octanol-water coefficients (log P) of the drugs have an influence on the uptake speed in the roots of the plants. The log P seems to have no influence on the translocation of the drugs from the root to the shoots. Furthermore, neither phase I nor phase II metabolization occurred inside the plants.

Background/objective: Calcium channel blockers, when taken in overdose quantities, can cause hyperglycemia requiring so-called hyperinsulinemic-euglycemic therapy. The objective of this report was to describe a patient with calcium channel blocker toxicity resulting from overdose of amlodipine.
Case Report: A 74-year-old man presented with a fall and loss of consciousness.

Background: Phaeochromocytoma multisystem crisis (PMC) is characterized by labile blood pressures (extremes of hypo- and/or hypertension) and multiorgan failure as a result of catecholamine excess. Initial stabilization requires pharmacological and/or mechanical circulatory support, followed by the institution of antihypertensives to correct the underlying pathophysiology.
Case Summary: A previously well 40-year-old male developed a sudden onset of breathlessness.

Scope: Triglyceride-based lipid emulsions are critical for total parenteral nutrition (TPN), but their long-term use has adverse effects, such as severe liver dysfunction necessitating improved formulations. This study compares the uptake mechanism and intracellular fate of novel glycerol-stabilized nano-sized lipid emulsions with conventional emulsions in CD4 T cells, focusing on their impact on cellular metabolism.
Methods And Results: Nanoemulsions were formulated with increased glycerol content.

Diabetes mellitus (DM) is a chronic metabolic condition, characterized by hyperglycaemia, oxidative imbalance, pancreatic β-cell death, and insulin insufficiency. Angiotensin II (Ang II) increases oxidative stress, inflammation, and apoptosis, and Ang II type 1 receptor (AT1R) blockers (ARBs) can ameliorate inflammatory response and oxidative stress. However, like other small-molecule drugs, free ARBs show poor efficacy and dose-limiting toxicities.

Wastewater surveillance is an effective and objective approach to monitor contaminant releases and drug usage in the catchment, the estimation requires accurate measurement. In this study, a novel diffusive gradients in thin-film (DGT) technique based on molecularly imprinted polymers (MIPs) for selective measurement of a class of widely prescribed cardiovascular drugs (β-blockers) in wastewater was developed. The synthesized MIPs showed strong affinity and selectivity for the target compounds.
