A novel nanocomposite for food packaging developed by electrospinning and electrospraying

Publication date: June 2019Source: Food Packaging and Shelf Life, Volume 20Author(s): Daiane Angelica Schmatz, Jorge Alberto Vieira Costa, Michele Greque de MoraisAbstractThe association of electrospinning and electrospraying can produce a new nanomaterial for coating sensitive bioactive compounds as phycocyanin and the final product of these process present characteristics which make it possible the application as food packaging with actives properties. The aim of this work was the development of a new nanofiber material with incorporated phycocyanin/polyvinyl alcohol nanoparticles (PC-PVAn) through electrospinning and electrospraying techniques. Nanoparticles were produced with 11% PVA and 2% PC (w v−1) upon a collector with deposited 12% polycaprolactone (PCL) or 13% poly-L-lactic acid (PLLA) nanofibers. The PC-PVA nanoparticles presented nanoencapsulation efficiency of 75.1 ± 0.2% and provided antioxidant activity by the ABTS, DPPH and reducing power methods. The results obtained potentiate the application of nanomaterials produced by the association of electrospinning and electrospraying techniques in active food packaging due to their good thermal and mechanical characteristics and antioxidant capacity, which protect food from deterioration and increase their shelf-life.

Conclusions/Importance: Anti-MJ messages designed to discourage use might heighten reactance and inadvertently lead to greater craving and intent to use. The link between reactance and craving may be more affectively mediated than the link between reactance and message rejection. PMID: 31418607 [PubMed - as supplied by publisher]

Conclusions: High screen time was the most prevalent lifestyle risk behavior independently associated with depressive symptoms. Multiple lifestyle changes and improvement of appearance satisfaction should be included in measures targeting adolescents for the prevention and treatment of depressive symptoms. Future studies should elaborate on the gender differences in other adolescent age groups. Appearance satisfaction should be acknowledged as an important confounder in future studies of lifestyle and depressive symptoms. PMID: 31419392 [PubMed - as supplied by publisher]

Publication date: Available online 16 August 2019Source: Sensors and Actuators A: PhysicalAuthor(s): Weina Liu, Xinwei Yang, Youtian Niu, Haoran SunAbstractIn this paper, a sub-wavelength resonance sensor is proposed to microwave detection applications. A meta-material element—multiple split ring resonator (MSRR) is used to improve the sensitivity of the sensor. Therefore, the sensor is based on micro-strip technology and consists of a micro-strip and a MSRR. It is observed that the strongest electric field of the sensor can achieve to 105V/m. So the sensor is very sensitive to capture changes of dielectric signals. ...

Publication date: Available online 16 August 2019Source: Pharmacology Biochemistry and BehaviorAuthor(s): Morales-Mulia MarcelaAbstractAlcohol use is frequently associated with mood disorders. Similarly, individuals suffering from these disorders have a higher risk of developing alcoholism. Several reports have implicated orexin signaling in different behaviors related to alcohol consumption, whereas antagonists block these actions. However, the involvement of orexin-1-receptor (Orx1R) in ethanol-induced anxiolysis remains relatively unexplored. The purpose of this study was to investigate whether intra-accumbal inhibition...

The objective of the present study was to investigate the association between hair and urine Al levels and obesity.MethodsA total of 206 lean and 205 obese non-occupationally exposed subjects (30-50 y.o.) were enrolled in the study. Hair and urine Al levels were assessed with ICP-MS. Laboratory quality control was performed using the certified reference materials of human hair, plasma, and urine.ResultsHair and urinary Al levels in obese subjects were significantly higher by 31% and 46% compared to the control levels, respectively. The presence of hypertension (41% cases), atherosclerosis (8%), type 2 diabetes melli...
