Turmeric, known for its curcuminoid-rich rhizome, particularly curcumin, exhibits notable antioxidant and antiviral properties. The likelihood of microbial contamination necessitates finding reliable techniques for subjecting the sample to radiation from this plant-based raw material. One alternative is to expose curcumin to radiation (e-beam), which was carried out as part of this research. Confirmation of the lack of curcumin decomposition was carried out using HPLC-DAD/MS techniques. Additionally, using the EPR technique, the generated free radicals were defined as radiation effects. Using a number of methods to assess the ability to scavenge free radicals (DPPH, ABTS, CUPRAC, and FRAP), a slight decrease in the activity of curcumin raw material was determined. The analysis of the characteristic bands in the FT-IR spectra allowed us to indicate changes in the phenolic OH groups as an effect of the presence of radicals formed.

Nowadays, several processes to enrich desired bioactive compounds in plant extracts have been developed. The objective of the present study was to assess the performance of bovine serum albumin in increasing the extractive yields of anthraquinones and diarylheptanoids from their respective raw plant powder extracts. Aloe emodin, rhein, emodin, and chrysophanol, from , , , and , and curcumin from were analyzed in parent dry extracts, solubilized either with water, ethanol, or hydro-alcoholic mixtures, and in ones treated with aqueous solutions of bovine serum albumin by HPLC with UV/Vis detection.

Macrophages are an integral part of the innate immune system and act as a first line of defense to pathogens; however, macrophages can be reservoirs for pathogens to hide and replicate. Tuberculosis, influenza virus, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are common diseases whose pathogens are uptaken into macrophages. Current treatments for diseases such as these are limited by the therapeutic delivery method, which typically involves systemic delivery in large, frequent doses.

Chemoprevention is one of the accessible strategies for preventing, delaying or reversing cancer processing utilizing chemical intervention of carcinogenesis. NAD(P)H quinone oxidoreductase 1 (NQO1) is a xenobiotic metabolizing cytosolic enzyme/protein with important functional properties towards oxidation stress, supporting its ability in detoxification/chemoprotective role. A set of 3,5-diylidene-4-piperidones (as curcumin mimics) bearing alkyl sulfonyl group were synthesized with potential NQO1 induction properties.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.

Atherosclerosis (AS) is a lipid-driven chronic inflammatory disease characterized by the presence of numerous proinflammatory cytokines, massive reactive oxygen species (ROS) and excess lipids, which together result in an overall inflammatory positive feedback loop in the plaque focus. Due to its excellent enzyme-like activity in ROS scavenging and inflammation inhibition, as well as its photothermal effects in the lipid efflux ability of foam cells, Prussian blue (PB) has greater potential in preventing inflammatory factor loops for enhanced treatment of AS than traditional nanozymes. In this study, the multifunctional nanozyme BSA@PB/Cur was synthesized by self-assembly of bovine serum albumin (BSA) with PB and further encapsulation of the anti-inflammatory drug curcumin (Cur).
