Physicochemical, antioxidant and antibacterial properties of fish gelatin-based edible films enriched with orange peel pectin: wrapping application

Publication date: Available online 20 January 2020Source: Food HydrocolloidsAuthor(s): Mourad Jridi, Ola Abdelhedi, Ali Salem, Hela Kechaou, Moncef Nasri, Yosra MenchariAbstractThe physicochemical, thermal and mechanical properties of blood orange peel pectin (BOPP) film blended with fish gelatin (F-G), at different ratios, were investigated. BOPP was first, tested for its antioxidant capacity, monitored through the β-carotene bleaching, DPPH radical-scavenging and reducing power activities. BOPP and gelatin blending was found to reduce the wettability of the gelatin film, whereas it slightly reduced its transparency. F-G:BOPP film prepared with equal ratios (50:50) showed the highest glass transition temperature (Tg ∼ 79 °C) and tensile strength (TS ∼ 14 MPa) values. The structure analysis of the blend films showed their homogeneity and miscibility, as revealed by the infrared spectra, the differential scanning calorimetry and the microstructure results. Of particular interest, blend films showed high antioxidant and antibacterial capacities, compared to the gelatin-based film and the best results were recorded in the F-G:BOPP (50:50) among all the other films, reaching 0.96, 50.36% and 67.36% for the reducing power, the β-carotene bleaching inhibition and the radical scavenging activity, respectively. Furthermore, the prepared films were used to wrap cheese in order to enhance their preservation. The results showed that the F-G:BOOP wrapping improved t...

CONCLUSIONS.: Our results confirm orbitofrontal structural deficits in BPD, while providing a framework and preliminary findings on identifying structural correlates of symptom dimensions in BPD, especially with dorsolateral and orbitofrontal cortices. PMID: 32093800 [PubMed - in process]

CONCLUSIONS.: Despite sharing a lower IQ and a higher prevalence of psychiatric disorders, brain abnormalities in BDo appear less pronounced (but are not absent) than in SZo. Lower ICV in SZo implies that familial risk for schizophrenia has a stronger association with stunted early brain development than familial risk for bipolar disorder.

Authors: Higuchi M Abstract The deposition of fibrillar tau aggregates has been implicated in Alzheimer's disease (AD) and allied neurodegenerative disorders collectively referred to as tauopathies. Growing non-clinical and clinical evidence has supported intimate links between tau fibrillogenesis and neuronal deteriorations, rationalizing the development of imaging agents for tau fibrils to gain etiological insights into tauopathies and to facilitate diagnostic and therapeutic approaches to these diseases. Radiochemicals derived from three major chemotypes were initially applied to positron emission tomography (PE...

Associations Between APOE Variants, Tau and α-Synuclein. Adv Exp Med Biol. 2019;1184:177-186 Authors: Rodriguez-Vieitez E, Nielsen HM Abstract Neurodegenerative diseases are characterized by the aggregation and deposition of misfolded proteins in the brain, most prominently amyloid-β (Aβ), tau and α-synuclein (α-syn), and are thus referred to as proteinopathies. While tau is a hallmark of Alzheimer's disease (AD) and other non-AD tauopathies, and α-synuclein is the pathological feature of the spectrum of synucleinopathies including Parkinson's disease (PD), Parkinson's...

Authors: Morisaki T, Fukuhara T, Matsuda E, Moritani S, Miyake N, Koyama S, Fujiwara K, Takeuchi H Abstract Lymphadenopathy is frequently observed in immunoglobulin G4 (IgG4)-related disease in some cases, and such cases are known as IgG4-related lymphadenopathy. The ultrasonography findings associated with IgG4-related lymphadenopathy have not been described in previous reports. Herein, we describe ultrasonography findings in two cases of IgG4-related lymphadenopathy in conjunction with histopathological findings. Combined ultrasound scanning with Doppler examination accurately represented the specific histopathol...

CONCLUSIONS: In cases of BCCs with thickness of ≤1 mm, there was a high correlation (r=0.870) of the tumor spread depth between micromorphological measurements and the results obtained using a 75 MHz transducer and in cases of BCCs with thickness of>1 mm, a very high correlation (r=0.951) of the tumor spread depth was observed between histomorphometry and30 MHz transducer measurements.
