Article Abstract
We propose a method for the quantitative determination of serotonin in blood serum using high-performance liquid chromatography with tandem mass spectrometry detection (HPLC-MS/MS) and online solid-phase extraction in a chromatographic system. This approach allows serotonin quantification in blood serum within a range of 0.5-2000 ng/ml, partially automates the sample preparation process, and minimizes the influence of matrix components. The method is designed for the quantitative measurement of serotonin levels in patients with various deviations of serotonin levels and associated diseases.

Background: Clinical and basic research suggests that exercise is a safe behavioral intervention and effective in improving cognition in vascular dementia (VD). However, despite global efforts, there is still no effective method to completely cure VD. This study aimed to investigate the effects of long-term exercise pretreatment on typical VD pathology in a rat model, and further compare the neuroprotective impacts of different exercise modalities on VD rats.

Secondary metabolites are important bioactive compounds for diet and medicine. This study optimizes the extraction of hydroethanolic herbal extracts using an EDGE (Energized Dispersive Guided Extraction) system, evaluates their antioxidant capacity, and analyzes correlations among antioxidant activity, total phenolic content, and individual compounds. A Doehlert matrix design was used to optimize extraction, having temperature and time as independent variables, and total phenolic content (mg GAE/g) as the response, quantified via the Folin-Ciocalteu method.

Ethnopharmacological Relevance: Primary dysmenorrhea (PD) is common and has a major impact on women's daily activities and quality of life. Wenjing Decoction (WD), a classic Chinese medicine formula, has been widely used for thousands of years in China to treat PD. However, the key pharmacodynamic substances in WD responsible for its anti-dysmenorrhea efficacy are still unclear.

Carprofen (CAR) is an NSAID commonly used in veterinary medicine that preferentially inhibits cyclooxygenase-2 (COX-2), thereby mitigating inflammation and pain while minimizing adverse effects linked to cyclooxygenase-1 (COX-1) inhibition. This study characterizes the pharmacokinetics of CAR in Siamese crocodiles (Crocodylus siamensis) and was conducted at an ambient temperature range of 27-30 °C following single intravenous (IV) or intramuscular (IM) administration at 2 mg/kg, and IM administration at 4 mg/kg. Plasma concentrations were determined using a validated high-performance liquid chromatography method with ultraviolet detection (HPLC-UV).
