Objective: To investigate effect of demethoxycurcumin on stability of curcumin.
Methods: To add the demethoxycurcumin to pure curcumin, the change of curcumin was determined by HPLC and the dynamics of curcumin degradation was investigated.
Result: The stability both obtained from alcohol and demethoxycurcumin improved the stabilization of curcumin, the demi-period of curcumin prolonged with the addition of demethoxycurcumin.
Conclusion: The commixture of curcumin and demethoxycurcumin are more stable than pure curcumin at the same conditions. Stability of curcumin is improved by demethoxycurcumin,it is crude stabilizing agent.

In women globally, breast cancer ranks as the second most frequent cause of cancer-related deaths, making up about 25% of female cancer cases, which is pretty standard in affluent countries. Breast cancer is divided into subtypes based on aggressive, genetic and stage. The precise cause of the problem is still unknown.

Obesity-induced muscle alterations, such as inflammation, metabolic dysregulation, and myosteatosis, lead to a decline in muscle mass and function, often resulting in sarcopenic obesity. Currently, there are no definitive treatments for sarcopenic obesity beyond lifestyle changes and dietary supplementation. Feruloylacetone (FER), a thermal degradation product of curcumin, and its analog demethoxyferuloylacetone (DFER), derived from the thermal degradation of bisdemethoxycurcumin, have shown potential antiobesity effects in previous studies.

This study investigated the effect of different-polarity aqueous ethanol solutions on the formation of V-type starch originating from corn starch. Scanning electron microscopy revealed that the morphology of starch transformed from a random lamellar structure to a granular structure with decreasing solution polarity. When the ethanol concentration increased from 40 % to 60 %, the crystallinity and single-helix ratio of V-type starch increased from 9.

Latent fingerprints (LFPs) are invisible impressions that need to be developed before being used for criminal investigation; however, existing fingerprint visualization techniques face challenges, such as complex preparation and poor contrast. To advance practical fingerprint detection, green-emissive micron-sized curcumin/kaolin composites were synthesized a facile and cost-effective one-step physical cross-linking method, which exhibited unprecedented performance in developing diversified marks, including LFPs, knuckle prints, palm prints, and footprints, with clear three-level details on various substrates. Notably, the powders successfully developed LFPs that were aged for 30 days and even up to 100 days, meeting the stringent requirements for comprehensive forensic application.

Objective To investigate the protective effect of curcumin (Cur) against arsenic-induced neuroimmune toxicity and the underlying molecular mechanisms in vivo. Methods Eighty SPF female C57BL/6 mice were randomly assigned to four groups: a control group, an arsenic-treated group, a Cur-treated group and an arsenic+Cur group, with 20 mice in each group. The control group received distilled water; the arsenic-treated group was given 50 mg/L NaAsO in the drinking water; the Cur-treated group was gavaged with 200 mg/kg of curcumin for 45 days; and the arsenic+Cur group received distilled water and was gavaged with 200 mg/kg of curcumin.
