Abstract: The present invention is a composition that can form an edible film or an edible liquid coating that can be applied to the surface of fresh fish (fillets or cuts) or fresh seafood. The present invention acts as a physical barrier preventing oxygen, water and microorganisms from entering the food product, and also acts as a bacteriostatic and antioxidant agent.

Abstract: The invention relates to self-assembled nanofibers of chitosan and bioactive compounds for use as nutraceuticals or drugs. Suitable bioactive compounds include molecules of a low molecular size with acid or lactone groups, aromatic rings and hydroxyls. The nanofibers are absorbed, without degradation, in the small intestine, containing and protecting the bioactive compounds until they reach target organs. The nanofibers also cross the blood-brain barrier, allowing the compounds to reach the brain where they act as a controlled release system. If the bioactive compounds are neuroprotectors, the nanofibers can treat or prevent neurodegenerative diseases, strokes and other diseases related to aging or associated with oxidative stress. The invention also relates to a method for obtaining the nanofibers involving mixing chitosan with the bioactive compounds and allowing self-assembly. The invention further relates to a dosage form containing the nanofibers, particularly for oral administration.

Abstract: Techniques for quantifying respiration using a wearable device are described. According to some aspects, a wearable device includes multiple thermal sensors thermally coupled to one or more heat spreaders. The wearable device may in some cases be small enough to be wearable between the mouth and nose of the patient, such as via an adhesive attachment to the upper lip. When the patient exhales, air is produced through the mouth and/or through the nose. Each heat spreader may absorb heat of exhaled air which may thermally propagate to a thermal sensor coupled to the heat spreader. By measuring the change in temperature over time measured by the thermal sensors, measures of respiration such as respiratory rate, minute volume and/or tidal volume of the patient may be determined. Such measures may be determined by the wearable device or by an external device to which data is transmitted.

Abstract: Natural composition for controlling bacterial infections in potatoes, lettuce, vegetables, cores and flowers in general comprising extracts from monofloral honey flavonoids and/or phenols that act independently as controller of various bacterial infections.
