Understanding lipid digestion is crucial for promoting human health. Traditional methods for studying lipolysis face challenges in sample representativeness and pre-treatment, and cannot measure real-time lipolysis in vivo. Thus, non-invasive techniques like magnetic resonance imaging (MRI) need to be developed.

Sea cucumbers are widely used in oriental cuisine due to their medicinal properties. Antioxidant, antifungal, antiviral, anticancer and neuroprotective activities have already been identified in several species and in different tissues. Among the class of compounds with biological activity are cerebrosides, which have important functions for the proper functioning of cells, especially neuronal cells.

The introduction of high-performance TLC (HPTLC) instrumentation that allows precise control of critical parameters has transformed the technique into an efficient and rapid tool for analyzing various metabolites, namely lipids. Although mass spectrometry (MS) has largely replaced lipid analysis techniques over recent decades due to its comprehensive lipidome profiling capabilities, it typically lacks the rapidity and simplicity of TLC. HPTLC remains advantageous due to its ease of use, simpler data interpretation, and compatibility with complementary techniques.

As an established analytical method, high-performance thin-layer chromatography (HPTLC) offers powerful capabilities. This study focused on its application to analyze chlorinated paraffins (CP) by planar solid phase extraction (pSPE). Based on previous work, an irradiation chamber was developed to investigate the derivatization process on planar thin-layers and ensure a robust and reproducible analysis.

Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis.
