Several novel molecules, 1-(3'-(9H-carbazol-4-yloxy)-2'-hydroxypropyl)-3-aryl-1H-pyrazole-5-carboxylic acid derivatives 3a-g were synthesized and screened to evaluate their cytotoxicity against cancer cells in vitro. The compounds 3a-g has been prepared by the reaction of ethyl 3-aryl-1H-pyrazole-5-carboxylate with 4-oxiranylmethoxy-9H-carbazole in moderate to excellent yields. The cytotoxicity of synthesized compounds was evaluated by a SRB (sulforhodamine B) assay against cancer cell such as SK-N-SH human neuroblastoma (NB), human A549 lung carcinoma, human breast cancer MCF-7 cell lines. The results showed that seven compounds can suppress SK-N-SH tumor cancer cell growth. Among them, compound 3d was the most effective small molecule in inhibiting SK-N-SH cell growth.

Burns carry a large surface area, varying in shapes and depths, and an elevated risk of infection. Regardless of the underlying etiology, burns pose significant medical challenges and a high mortality rate. Given the limitations of current therapies, tissue-engineering-based treatments for burns are inevitable.

Macrophages remove apoptotic cells via phagocytosis, also known as efferocytosis, during inflammation to maintain tissue homeostasis. This process is accompanied by various metabolic changes in macrophages including the production of lipid metabolites by fatty acid oxygenases. Among these, highly reactive metabolites, called lipid-derived electrophiles (LDEs), modify cysteines and other nucleophilic amino acids in intracellular proteins.

Polyelectrolyte multilayers (PEMs) based on hyaluronic acid (HA) and poly (diallyldimethylammonium chloride) (PDDA) were deposited on oxidized polystyrene (PS) via the layer-by-layer (LbL) method. The X-ray photoelectron spectroscopy (XPS) confirmed the PEM deposition on PS, and atomic force microscopy (AFM) indicated that the surface roughness of PS also increased after PEM deposition. The PEMs significantly enhanced PS wettability, reducing the contact angle from 73° on PS to 24° on PDDA-terminated (PDDA/HA) PEM (2.

Metabolomics provides powerful tools that can inform about heterogeneity in disease and response to treatments. In this exploratory study, we employed an electrochemistry-based targeted metabolomics platform to assess the metabolic effects of three randomly-assigned treatments: escitalopram, duloxetine, and Cognitive-Behavioral Therapy (CBT) in 163 treatment-naïve outpatients with major depressive disorder. Serum samples from baseline and 12 weeks post-treatment were analyzed using targeted liquid chromatography-electrochemistry for metabolites related to tryptophan, tyrosine metabolism and related pathways.

The increasing frequency of cyanobacterial blooms, particularly those induced by Microcystis aeruginosa (M. aeruginosa), poses severe economic, ecological and health challenges due to the production of microcystins (MCs). Environmental parameters such as light and nutrient availability influence MCs production, while the role of dissolved organic matter (DOM) photochemical processes in regulating these remains unclear.
