The smart labels prepared via the casting method and molten 3D printing method have a long heating time at high temperature and a dense network structure, resulting in a decrease in the color response ability of the labels. Therefore, this study uses a nonphase change foam 3D printing method with a shorter heating time to improve the color sensitivity of smart labels. By the pH driving method, the blending and pregelation of sodium alginate (Alg) can extend the drainage time of the interfacial film to the maximum extent, thus further improving the foam stability of egg white protein (EWP) and endowing the interfacial adsorption layer with better flexibility and fluidity.

Article Synopsis
  • * Increased concentrations of these metal ions improve key properties of the LDL gel, including hardness and energy storage, as well as enhancing the gel's secondary structure and aggregation behavior.
  • * The findings suggest that the addition of bivalent ions exposes more proteins and lipids, strengthening hydrophobic interactions and leading to a denser gel network, with practical applications in improving gel-like egg product processing technology.

The 'African eye worm', also known as Loa loa, is filarial nematode that is commonly, transmitted by deer flies. A history of recent travel to endemic countries near western, Africa is common in patients with Loiasis. While a majority of patients infected with Loa, loa are asymptomatic, common presentations of Loiasis include localized areas of, edema, Calbar swellings, and ocular symptoms secondary to the migration of worms, through the spaces within the eye.

The heart of date palm (HDP) is a nutrient-dense vegetable, rich in protein and carbohydrate, obtained from the core of palm trees. Carbohydrates are the major component of the heart of date palm, providing a quick source of energy and fiber content can help digestion and contribute to feeling of fullness, making it good addition to a balanced diet. The study investigated the potential of incorporating HDP into low-fat bio fermented camel milk (BCM).

  • This study explores using high internal phase Pickering emulsions (HIPPEs) to enhance the health and safety of pork while also improving its texture and cooking properties.
  • HIPPEs significantly increased the viscosity and shear recovery of pork gel, making it better for 3D printing and suitable for individuals with swallowing difficulties.
  • The adjusted pork gel reduced cooking loss and improved digestibility, highlighting its potential for creating specialized diets for dysphagic patients.

  • The study investigates the stability and age-friendliness of high internal phase Pickering emulsions (HIPPEs) stabilized with egg yolk and carboxymethyl cellulose (EYCMC), revealing differences in their aggregation states.
  • EYCMC exhibits distinct behaviors at the oil-water interface, influenced by electrostatic interactions and kinetics, which contribute to the stability of HIPPEs.
  • Results show that soluble complexes provide the best stability, indicating potential applications in food innovations, including 3D printing and digestion simulations for the elderly.

  • Researchers created a new edible film by mixing purified flavonoids from Moringa oleifera leaves with chitosan at different concentrations (0.5-4%), enhancing its physical and mechanical properties.
  • The highest concentration (4%) significantly improved water vapor permeability, mechanical strength, and antioxidant capacity, while also showing effective inhibition of harmful bacteria in beef burgers.
  • Overall, the study suggests that these chitosan-flavonoid composite films could be used in the food industry to extend the shelf-life and improve the safety of packaged foods.

Free-floating thrombus (FFT) of the aorta is a rare condition characterized by a nonadherent portion of thrombus floating within the aortic lumen. Hypercoagulability is a well-known complication of COVID-19 infection, and thromboses related to COVID-19-related hypercoagulability commonly present in the form of venous or arterial thrombosis such as deep vein thrombosis (DVT), pulmonary embolism (PE), ischemic stroke, and myocardial infarction. Unfortunately, FFT associated with COVID-19 infection has been rarely reported in the literature.

The low solubility and stability of fat-soluble curcumin in water limit its application in active packaging. This study explored the use of a pH-driven method to investigate the preparation and enhancement of the performance of films loaded with curcumin in a matrix of sodium alginate (Alg) and egg white protein (EWP). In this study, the EWP, Alg, and curcumin primarily bind through hydrogen bonding, electrostatic interactions, and hydrophobic interactions.

Hyperuricemia contributes significantly to gout arthritis pathogenesis, which promotes urate crystal deposition in the joints and activates joint-resident macrophages and circulating monocytes to initiate a state of inflammatory arthritis. In the joint, macrophages have an immune defense role where the presence of urate crystals results in the inflammatory mediators secretion, inflammatory cells recruitment to the joint, and shift macrophage population toward M1 pro-inflammatory phenotypes. Current treatment modalities of gout arthritis have side effects that limit their use in the elderly.

Background: Extreme heat events (EHEs), driven by anthropogenic climate change, exacerbate the risk of cardiovascular disease (CVD), although the underlying mechanisms are unclear. Disturbances in sleep health, caused by excessive heat, may be one way EHEs increase the risk of incident or recurrent CVD. Our objective was to systematically review the empirical peer-reviewed literature on the relationship between EHEs, sleep health, and cardiovascular measures and outcomes, and narratively describe methodologies, evidence, and gaps in this area.
