Preparation and characterization of active films based on oregano essential oil microcapsules/soybean protein isolate/sodium carboxymethyl cellulose.

This study aimed to prepare oregano essential oil microcapsules (EOMs) by the active coalescence method using gelatin and sodium alginate as wall materials and oregano essential oil (OEO) as the core material. EOMs were added to the soybean protein isolate (SPI)/sodium carboxymethyl cellulose (CMC) matrix to prepare SPI-CMC-EOM active films, and the physical and chemical features of the active films and EOMs were characterized. The results showed that the microencapsulated OEO could protect its active ingredients.

Designing a resilient retail supply network for fresh products under disruption risks.

The retail sector supplies the daily fresh products and increasingly plays a key role in the stability and livability of cities. However, public health events such as COVID-19 have caused frequent product shortages in recent years. The risk of fresh product shortages not only causes retailers to lose profits, but also affects the normal life of residents.

Design of carboxymethyl chitosan-reinforced pH-responsive hydrogels for on-demand release of carvacrol and simulation of release kinetics.

pH-responsive carboxymethyl chitosan (CC)/sodium alginate (SA)/carvacrol (CA) hydrogels were prepared using CC and SA as wall materials. The formation of hydrogels is attributed to electrostatic interactions and hydrogen bonding. The thermostability of the hydrogels was improved with increasing CC content.

Preparation, characterization and application of poly(lactic acid)/corn starch/eucalyptus leaf essential oil microencapsulated active bilayer degradable film.

This study aimed to develop a composite bilayer film based on corn starch (CS)/polylactic acid (PLA). The film had a hydrophobic outer layer and an absorbent inner layer. A natural bioactive substance was incorporated into the inner layer, namely, eucalyptus essential oil microcapsules (EOM).

Analyses of crime patterns in NIBRS data based on a novel graph theory clustering method: Virginia as a case study.

This paper suggests a novel clustering method for analyzing the National Incident-Based Reporting System (NIBRS) data, which include the determination of correlation of different crime types, the development of a likelihood index for crimes to occur in a jurisdiction, and the clustering of jurisdictions based on crime type. The method was tested by using the 2005 assault data from 121 jurisdictions in Virginia as a test case. The analyses of these data show that some different crime types are correlated and some different crime parameters are correlated with different crime types.

[Effect of danhong injection on ET-1, sP-sel, and hs-CRP in patients with acute coronary syndrome undergoing percutaneous coronary intervention].

Objective: To observe the effect and explore the action mechanism of Danhong Injection (DHI) on serum levels of endothelin-1 (ET-1), soluble P-selectin (sP-sel) and high sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).

Methods: Seventy ACS patients scheduled to receive PCI were assigned to two groups. Around PCI, the 34 patients in the control group were treated with conventional therapy and the 36 in the DHI group treated with conventional therapy combined with DHI treatment given from the day of PCI to the 14th day after operation at the dose of 40 mL per day by dissolving in 250 mL of 5% glucose for venous dripping.
