Abstract
Food packaging has a crucial function in the modern food industry. New food packaging technologies seek to meet consumers and industrial's demands. Changes related to food production, sale practices and consumers' lifestyles, along with environmental awareness and the advance in new areas of knowledge (such as nanotechnology or biotechnology), act as driving forces to develop smart packages that can extend food shelf-life, keeping and supervising their innocuousness and quality and also taking care of the environment. This review describes the main concepts and types of active and intelligent food packaging, focusing on recent progress and new trends using biodegradable and biobased polymers. Numerous studies show the great possibilities of these materials. Future research needs to focus on some important aspects such as possibilities to scale-up, costs, regulatory aspects, and consumers' acceptance, to make these systems commercially viable.

Abstract
BACKGROUND The development of brewer's spent grain protein (BSG-PC) films with potential active packaging properties was investigated. Films were prepared by casting protein dispersions at different pH values (2, 8, 11), plasticizers [polyethylene glycol (PEG) or glycerol] and levels (0-0.25 g g-1 ) of PEG. Mechanical, water-barrier and solubility, optical, antioxidant (reducing power, ABTS•+ and lipidic radical scavenging), and antimicrobial properties of films were determined. Also, the structural characteristics of films were evaluated by attenuated total reflectance-Fourier transform infrared spectroscopy. RESULTS Only films prepared at pH 2 and plasticized by PEG were homogeneous in appearance and could be manipulated; thus, different levels of PEG were studied at this pH. Higher PEG concentrations increased water solubility, water vapor permeability and elongation at break, and decreased tensile strength and elastic modulus. PEG increased α-helix structure only when 0.10 g PEG g-1 BSG-PC was used. This could be related to the better mechanical properties of F0.10 films (higher tensile strength, and elastic modulus) with respect to the other films. Antioxidant activity depended on PEG concentration, whereas no antimicrobial properties against Bacillus cereus, Salmonella newport and Penicillium corylophylum were detected. CONCLUSION The formulations with 0.10 and 0.15 g PEG g-1 BSG-PC appear to be the most promising, balancing mechanical, water-barrier properties and the antioxidant capacity of these films. Moreover, BSG proteins could be a cheap alternative for the preparation of biodegradable films, which are capable of being used as active food packaging. © 2020 Society of Chemical Industry.

Abstract
This work deals with the preparation of cellulose nanocrystals (CNC) from microcrystalline cellulose by acid hydrolysis, discusses how their characteristics varied according to the drying technique used for their conservation and analyzes their re-dispersion in water. A stable water dispersion of "rod" or "needle" type CNC (≈5 nm of diameter, 276 nm of length and 41 mV of Z potencial) was initially prepared and then dried by lyophilization and spray. Thus powders with similar cristalinity but different morphology were obtained, while CNC seemed to aggregate in such an extent that hindered their re-dispersion in water. Only lyophilized CNC could be re-dispersed in water and maintained stable in dispersion for at least 24 h, when working with concentrations of CNC higher than a certain minimum value (3 %) and after submitting them to intense ultrasound treatments. The tested time achieved should be enough to allow their subsequent use in several applications.

Abstract
1,2-dihydroxybenzenes (DHBs) are organic compounds which are widely studied as they are applied to advanced oxidation processes (AOPs). These compounds are also related to the development of oxidative stress, wood biodegradation, and neuronal disease in humans. DHBs are metal ligands with pro-oxidant and antioxidant properties. These activities are related to their chelation properties and a consequence of the deprotonation of their hydroxyl groups. In literature, there are several pKa values for the hydroxyl groups of DHBs. These values vary depending on the experimental conditions or the algorithm used for calculation. In this work, an experimentally validated computational method was implemented in aqueous solution for pKa determination of 24 DHBs. The deprotonation order of the hydroxyl groups in DHB was determined observing a selective deprotonation, which depended on the ability of the substituent to donate or withdraw electron density over the ring.

Abstract
The aim of this work was to study the physicochemical and antioxidant properties of phycobiliproteins-phycocolloids-based films, obtained from mixtures of two aqueous fractions extracted from Porphyra columbina red seaweed, one enriched in phycocolloids (PcF) and the other in phycobiliproteins (PF). Films with different ratios of PF:PcF (0, 25, 50, 75, 100% [w/w]) and without plasticizer addition were prepared by casting. PcF films had excellent mechanical properties (tensile strength ∼50MPa, elongation at break ∼3% and an elastic modulus ∼17.5MPa). The addition of PF to formulations exerted a plasticizing effect on the PcF matrix, which was manifested in moisture content, water solubility and mechanical properties of the resulting films but not in its water vapour permeability. The antioxidant capacity (TEAC) of the PcF films was significantly increased by the addition of PF and a direct relationship between TEAC and the total phenolic compounds (r(2)=0.9998) and R-phycoerythrin (r(2)=0.9942) was observed.

Abstract
A 73 year-old white male, living in the interior of the state of Mato Grosso do Sul, in central Brazil, after an initial diagnosis of sinusitis was transferred to the neurology service with a 3-day evolution of intracranial hypertension. Exams showed lymphocytic leukemia and a tumor-like lesion, either an expanding inflammatory process such as an abscess or a neoplasm. Treatment with Ceftriaxone and Decadron was started and intracranial hypertension was controlled. Methotrexate was injected on the occasion of the next puncture considering a possible leukemia infiltration. Flagellate forms of T. cruzi were observed in the CSF and treatment with Benznidazole was started. After 4 days the CSF presented fractionated forms of trypomastigotes. The protein level was 27%. Signs of intracranial hypertension ceased. Tomography and magnetic resonance images showed an important reduction of the tumor-like lesion. The clinical condition of the patient improved.
