Background: Benzoyl peroxide (BPO) has been a mainstay of topical acne treatment for years. However, is frequently accompanied by cutaneous irritation and erythema. To reduce these side effects many novel drug delivery systems have been developed in the past, of which solid lipid nanoparticles (SLN) demonstrate clear dominance. Hence, we developed a facile method to prepare stable SLN of BPO and evaluated their anti-bacterial activity.
Results: BPO-SLN optimized using 2(3) full factorial design provided high occlusion factor, low permeation rate, increased drug deposition, reduced skin irritation and strong anti-bacterial activity in contrast with marketed product.
Conclusion: Desired goals were achieved by factorial design approach in shortest possible time with minimum number of experiments. The developed BPO-SLN system provided controlled drug release, thereby reducing the well-known side effects.

Reprogramming of energy metabolism to support cellular growth is a "hallmark" of cancer, allowing cancer cells to balance the catabolic demands with the anabolic needs of producing the nucleotides, amino acids, and lipids necessary for tumor growth. Metabolic alterations, or "addiction", are promising therapeutic targets and the focus of many drug discovery programs. Asparagine metabolism has gained much attention in recent years as a novel target for cancer therapy.

Pancreatic ductal adenocarcinoma (PDAC) is one of the worst solid malignancies in regard to outcomes and metabolic dysfunction leading to cachexia. It is alarming that PDAC incidence rates continue to increase and warrant the need for innovative approaches to combat this disease. Due to its relatively slow progression (10-20 years), prevention strategies represent an effective means to improve outcomes.

Background/objectives: Lavender has been utilized for its medicinal properties since ancient times, with numerous health benefits reported. This study aimed to valorize solid waste from lavender essential oil production by developing a novel lavender extract from solid lavender residues. The extract's preclinical safety and efficacy were evaluated with emphasis on plasma lipid and lipoprotein metabolism, glucose tolerance, and adipose tissue metabolic activity.

Parkinson's disease (PD) is a debilitating neurodegenerative disorder characterized by motor and non-motor symptoms, with limited effective treatment options. This study proposes a novel approach utilizing intranasal delivery of carbenoxolone (CBX) via chitosan-coated solid lipid nanoparticles (CS-coated SLNs) to manage PD symptoms by enhancing CBX delivery and brain targeting. Formulated CS-coated SLNs exhibited favorable quality attributes including particle size (164 ± 0.

In order to study the change rule of freshness and acid ions in reconstituted tobacco slurry, the content changes of 17 organic acids and 5 inorganic anions in reconstituted tobacco slurry with different residence times under confined condition were determined by on-line solid-phase extraction ion chromatography in this study. The results showed that the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were regular and consistent, and the trends of the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were correlated with each other in a highly significant way. Taking the evaluation of olfactory aroma and sensory quality qualities of reconstituted tobacco pulps with different residence times as a benchmark, it was found that the variation patterns of nitrate ions and isovaleric acid in reconstituted tobacco pulps with oscillation time were consistent with the variation patterns of olfactory and sensory qualities in the process of closed oscillation; compared with the fresh pulp, the olfactory aroma and sensory qualities of tobacco pulps had unpleasant odours appearing when the content of nitrate ions was reduced by about 48%.
