ABSTRACT

Since ancient times, Aloe vera L. (AV) has attracted scientific interest because of its multiple cosmetic and medicinal properties, attributable to compounds present in leaves and other parts of the plant. The collected literature data show that AV and its products have a beneficial influence on human health, both by topical and oral use, as juice or an extract. Several scientific studies demonstrated the numerous biological activities of AV, including, for instance, antiviral, antimicrobial, antitumor, and antifungal. Moreover, its important antidepressant activity in relation to several diseases, including skin disorders (psoriasis, acne, and so on) and prediabetes, is a growing field of research. This comprehensive review intends to present the most significant and recent studies regarding the plethora of AV's biological activities and an in-depth analysis exploring the component/s responsible for them. Moreover, its morphology and chemical composition are described, along with some studies regarding the single components of AV available in commerce. Finally, valorization studies and a discussion about the metabolism and toxicological aspects of this "Wonder Plant" are reported.

ABSTRACT

Colloidal food products, such as emulsions, foams, gels, and dispersions, are complex systems that need the presence of stabilizing agents to enable their formation and provide stability. Proteins are often used for food foams and emulsions because of their ability to lower interfacial tension and make viscoelastic interfaces. Generally, to improve the resistance against rupture, polysaccharides are used in association with the proteins. Pectin is a complex polysaccharide that can help to stabilize foams or emulsions. This work aims at studying the mechanical resistance of the interface formed by mixtures of ß-casein and pectin at high and low methoxylation degrees at the air/water interface using dilatational and shear kinematics. Frequency sweep tests, in the linear region, were performed in shear at different aging times and in dilatational mode, and the rheological data were analyzed. The transient data of the surface tension were analyzed by kinetic models to obtain the characteristic rates of the interfacial phenomena. The kinetic mechanisms of the protein/pectin mixed systems are controlled by protein and show a weak gel behavior for short aging times. The interfaces obtained with both pectins in a mixture with ß-casein evolved with time, gelling and showing a solid-like behavior at concentrations of 1 and 10 g/L and after 3.5 h of aging time. The interfacial shear trend obtained suggests a good stabilizing effect of the pectins from citrus with long aging times.

ABSTRACT

Recently, the research on innovative food packaging has been oriented toward biodegradable materials to lower the environmental impact generated by conventional plastics. The films often carry functional additives interacting with the matrix and modifying its physical properties. In this work tannin, a scarcely exploited active additive, was used to obtain potato starch-based films, and its content was optimized on the basis of mechanical and microscopic tests. Rheological measurements were adopted to evaluate the tannin-starch interaction and the microstructure of the film forming solutions (FFSs). Their thickness, color, thermal conductivity, elastic modulus (Eel), elongation at break (EAB), surface wettability and water solubility were evaluated. Furthermore, microstructure was investigated through Fourier-transform infrared spectroscopy (FTIR), polarized light (POM) and scanning electron microscopy (SEM). It was observed that all FFSs behave as weak gels and tannin addition weakens the gel structure and decreases the gelatinization temperature from about 60 °C to 57 °C. Plastic and deformable films (Eel = 1.96 MPa and EAB = 189 %) were obtained at low tannin fractions, whereas, at a higher concentration, stiffer films (Eel = 12 MPa and EAB = 10 %), with hydrophobic behavior were produced. Among the tested tannin fractions, an intermediate value of 1.7 % (w/w) was found to be promising for industrial purposes.

ABSTRACT

In recent years, the increasing demand for alternative foods has shifted research toward new sources enriched with nutraceutical molecules. It is well known that many diseases are caused by oxidative stress; thus, the supplementation of antioxidants has been proposed to reduce it. Cannabis sativa L. is an interesting species that could provide an alternative source of antioxidants. This work aimed to investigate the possibility of optimizing the yield of cannabidiol (CBD) and recovering it from residual biomass (stalks), valorizing the residual biomass, and using this for protein bar preparation. Different extraction methods were used, and High-Pressure Liquid Chromatography (HPLC) analysis was used to analyze the extracts. Antioxidant power was investigated using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays. The best results in terms of CBD yield were obtained via dynamic maceration after decarboxylation with a quantity of 26.7 ± 2 mgCBD/graw material from inflorescences. The extract also shows good antioxidant power with an IC50 value of 38.1 ± 1.1 µg/mL measured using the DPPH assay. The CBD extract was added to the hemp oil to obtain dough for protein bars. The doughs were studied by taking rheological and technological measurements, and it was found that the protein bars could provide an excellent means for the consumption of products enriched with antioxidants because their CBD anti-inflammatory activity is preserved after cooking.

ABSTRACT

(1) Background: Recent research on the valorization of agro-industrial waste has attempted to obtain new products. Grape residue is a waste product used in the grape wine industry that is rich in anthocyanins, as well as leaves and waste parts from red cabbage processing. Anthocyanins, thanks to their various functionalities, can be recovered and used as active and intelligent agents in food packaging. Anthocyanins have antioxidant properties that help to prevent cardiovascular disease. (2) Methods: In this study, the process of extracting waste was studied using solvent and supercritical CO2 extraction. The obtained anthocyanins were used in starch-based food film formulations. Several formulations were studied using rheometric techniques and the effect of adding anthocyanins on optimal film formulation was investigated. (3) Results: Solvent extractions resulted in a maximum extraction yield. The extracts obtained were used for the preparation of coating and edible films, optimized in the formulation. (4) Conclusions: The addition of anthocyanins to films resulted in increased sample structuring and mechanical properties that are valid for applications, like dipping using coverage methods. The packaging is also attractive and pH-sensitive.

ABSTRACT

Proteins are widely used in the formation and stabilization of multiphase systems, thanks to their ability to adsorb at the interface reducing the interfacial tension and promoting the formation of viscoelastic layers. Owing to the growing consumer demand, the food industry is moving toward the growing use of plant-based proteins, suitable for consumers who do not eat products of animal origin, for either ethical or health reasons. Nevertheless, the scientific literature lacks information on the surface activity and emulsifying ability of these proteins. In this work, the interfacial properties of soy, hemp and brown rice isolate proteins were investigated at the interface with commercial sunflower oil (O/W) to evaluate their characteristics in view of potential uses in food applications such as emulsions, sauces, dressing, topping and soft foods. Dilatational and shear kinematic, with pendant drop and magnetic rod techniques, respectively, were used. The dilatational analysis was performed in static and dynamic conditions, to obtain the equilibrium adsorption isotherms and the rheological parameters of the interfacial layers under both oscillation and stress relaxation. The interfaces were studied in shear conditions with small amplitude oscillations and creep tests. The obtained results evidenced that all tested proteins are able to build a strong viscoelastic layer with properties comparable to those of animal proteins. Brown rice protein seems particularly effective in reducing the interfacial tension even if shear tests evidence that the interface is weaker than that obtained using hemp or soy protein. Hemp protein seems very promising for potential practical uses yielding intermediate interfacial tensions and strong viscoelastic layers.

ABSTRACT

Emulgels are biphasic emulsified systems in which the continuous phase is structured with a specific gelling agent. In this work, a rheological and microscopic investigation of O/W emulgels prepared by structuring the aqueous (continuous) phase with citrus fiber was carried out with the aim of designing their macroscopic properties for food uses and predicting their characteristics with a rheological model. According to previous investigations, fiber suspensions behave as "particle gels" and, consequently, the derived emulgels' properties are strongly dependent on the fiber concentration and on process conditions adopted to produce them. Therefore, a rotor-stator system was used to prepare emulgels with increasing fiber content and with different levels of energy and power used for mixing delivered to the materials. An investigation of particle gels was then carried out, fixing the operating process conditions according to emulgel results. Furthermore, the effect of the dispersed (oil) phase volume fraction was varied and a modified semi-empirical Palierne model was proposed with the aim of optimizing a correlation between rheological properties and formulation parameters, fixing the process conditions.

ABSTRACT

The impaired ability to feed properly, evident in oncologic, elderly, and dysphagic patients, may result in malnutrition and sarcopenia. Increasing the consumption of dietary proteins by functional foods and enriching their composition by adding beneficial nutrients may represent an adjuvant therapy. We aimed to evaluate the safety and the positive effects of a standard diet (SD) supplemented with whey-derived protein puddings (WDPP), with appropriate rheological properties, and hemp seed oil (HSO), rich in polyphenols. Rats were assigned to SD, WDPP, WDPP plus hemp seed oil (HSOP), and HSO supplemented diets for eight weeks. "Anthropometric", metabolic, and biochemical variables, oxidative stress, tissue injury, liver histology, and cardiac susceptibility to ischemia/reperfusion were analyzed. All the supplementations did not induce significant changes in biochemical and metabolic variables, also in relation to glucose tolerance, and livers did not undergo morphological alteration and injury. An improvement of cardiac post-ischemic function in the Langendorff perfused heart model and a reduction of infarct size were observed in WDPP and HSOP groups, thanks to their antioxidant effects and the activation of Akt- and AMPK-dependent protective pathways. Data suggest that (i) functional foods enriched with WDPP and HSOP may be used to approach malnutrition and sarcopenia successfully under disabling conditions, also conferring cardioprotection, and that (ii) adequate rheological properties could positively impact dysphagia-related problems.

ABSTRACT

Bigels are interesting semisolid formulations with better properties for different applications such as cosmetics and pharmaceutical systems. Due to the mixing of two phases of different nature (polar and apolar), bigels possess some interesting features like ability to deliver hydrophilic and hydrophobic drugs, better spreadability and water washability, improved permeability of drugs, enhanced hydration of stratum corneum and ability to manipulate the drug release rate. The main objective of this review article is to provide a thorough insight into the important characteristics of bigels together with the discussion on modelling of bigel systems to relate their properties with individual constituents and different parameters. Moreover, some important applications of bigels are also discussed by considering some examples from the literature.

ABSTRACT

BACKGROUND: Atopic dermatitis (AD) is a chronic, recurrent, inflammatory skin disorder which may persist or directly start in adults. This is an open-label prospective study to clinically and instrumentally evaluate the effects of an emollient glycerin and paraffin-based cream and a gentle refatting cleanser in the management of mild to moderate adulthood AD. METHODS: Fifty adult patient with mild to moderate AD were recruited at the Professional Dermatology and Allergology Outpatient Clinic of the San Gallicano Dermatological Institute of Rome, between November 2016 and January 2018. The patients applied the emollient cream twice daily for 2 months. To assess the efficacy of the cream, two different areas of treatment were identified in each patient's limbs. The outcome was evaluated at 30 days (T1) and 60 days (T2) of treatment comparing to baseline (T0) by means of clinical evaluation, Dermatology Life Quality Index (DLQI) questionary, transepidermal waterloss (TEWL) and corneometry measurements. RESULTS: Clinical evaluation showed significative improvement of skin xerosis, fissuring, itching and erythema. Consistently, a significative reduction of TEWL and an improvement in skin hydration was also detected. A significative improvement of DLQI score was also detected. CONCLUSIONS: Study treatment was well tolerated and showed significative improvement of clinical and instrumental parameters evaluated. The topical daily use of an emollient glycerin and paraffin-based cream and a gentle refatting cleanser seems to be a useful tool in the treatment of mild to moderate adulthood AD improving quality of life.

ABSTRACT

Zearalenone (ZEN) is an estrogenic mycotoxin occurring in Fusarium-infected cereals. Glucosylation is an important plant defense mechanism and generally reduces the acute toxicity of mycotoxins to humans and animals. Toxicological information about ZEN-glucosides is limited due to the unavailability of larger amounts required for animal studies. HvUGT14077, a recently-validated ZEN-conjugating barley UDP-glucosyltransferase was expressed in Escherichia coli, affinity purified, and characterized. HvUGT14077 possesses high affinity (Km = 3 µM) and catalytic efficiency (kcat/Km = 190 s-1·mM-1) with ZEN. It also efficiently glucosylates the phase-I ZEN-metabolites α-zearalenol and ß-zearalenol, with kcat/Km of 40 and 74 s-1·mM-1, respectively. HvUGT14077 catalyzes O-glucosylation at C-14 and C-16 with preference of 14-glucoside synthesis. Furthermore, relatively slow consecutive formation of 14,16-di-glucosides was observed; their structures were tentatively identified by mass spectrometry and for ZEN-14,16-di-glucoside confirmed by nuclear magnetic resonance spectroscopy. Recombinant HvUGT14077 allowed efficient preparative synthesis of ZEN-glucosides, yielding about 90% ZEN-14-glucoside and 10% ZEN-16-glucoside. The yield of ZEN-16-glucoside could be increased to 85% by co-incubation with a ß-glucosidase highly selective for ZEN-14-glucoside. Depletion of the co-substrate UDP-glucose was counteracted by a sucrose synthase based regeneration system. This strategy could also be of interest to increase the yield of minor glucosides synthesized by other glucosyltransferases.

ABSTRACT

Bigels are biphasic systems formed by water-based hydrogels and oil-based organogels, mainly studied, in the last few years, for pharmaceutical and cosmetic application focused on the controlled delivery of both lipophilic and hydrophilic active agents. The rheological properties of bigels depend on both the amount and the rheological characteristics of single structured phases. Moreover, it can be expected that, at large fractions of one of the starting gels, systems more complex than oil-in-water or water-in-oil can be obtained, yielding bicontinuous or matrix-in-matrix arrangement. Model bigels were investigated from a microstructural (i.e. microscopy and electrical conductivity tests) and rheological point of view. The hydrogel was prepared by using a low-methoxyl pectin whereas the organogel was prepared by using olive oil and, as gelator, a mixture of glyceryl stearate and policosanol. Model bigels were obtained by increasing the amount of organogel mixed with the hydrogel, and microstructural characterisation evidenced an organogel-in-hydrogel behaviour for all investigated samples, even though at the highest organogel content a more complex structure seems to arise. A semi-empirical model, based on theoretical equations developed for suspensions of elastic spheres in elastic media, was proposed to relate bigel rheological properties to single phase properties and fractions.

ABSTRACT

The microstructure of organogels based on monoglycerides of fatty acids (MAGs) and policosanol and on different edible oils was investigated by using different techniques (calorimetry, nuclear magnetic resonance, infrared spectroscopy, rheology, polarized light microscopy) towards a better understanding and control of the oil gelation phenomena. Dynamic moduli were related via a fractal model to microstructural information such as solid content and fractal dimension. Infrared spectroscopy evidenced that network structure in MAGs gel is mainly due to hydrogen bonding, whereas in policosanol system is mainly given by van der Waals interactions. Because of the different relative contribution of molecular interactions, the investigated organogelators exhibit a distinguished macroscopic behavior. MAGs are sensitive to the utilized oil and structuration occurs quickly, even though at a temperature lower than policosanol. Policosanol organogels exhibit a behavior independent of the used oil and a slower gelation rate, as a result of the weaker van der Waals interactions. Nevertheless, at lower concentration a stronger final gel is obtained, probably due to of the large number of interactions arising among the long alkyl chains of the fatty alcohols. Obtained results evidenced that policosanol is very effective in gelation of different oils and seems promising for potential commercial uses.

ABSTRACT

BACKGROUND: Pemphigus vulgaris (PV) is an autoimmune blistering disease mediated by IgG autoantibodies targeting desmogleins (Dsgs). The anti-CD20 monoclonal antibody rituximab is increasingly used in corticosteroid-resistant PV patients. In a subset of rituximab-treated patients in remission, high ELISA index values have been reported; however, their significance remains so far unclear. OBJECTIVE: To address the discrepancy between anti-Dsg3 serum antibody titers and disease severity. MATERIALS & METHODS: 6 rituximab-treated PV patients were prospectively followed-up for two years and anti-Dsg3 autoantibodies levels and pathogenic activity were measured. RESULTS: All patients achieved complete remission without any serious side effects. Both anti-Dsg3 autoantibodies (p = 0.031) and their pathogenic activity (p = 0.003) were significantly related to disease severity. However, in selected patients, the dissociation index was a more sensitive indicator for PV clinical activity than the ELISA index. CONCLUSION: Our findings have demonstrated the existence of non-pathogenic autoantibodies in PV patients in remission, establishing the basis for the design of a system able to precisely monitor the course of disease.

ABSTRACT

Low molecular weight organogels are semisolid systems structured by the assembly of molecules that crystallise under suitable process conditions. The inner microstructure of organogels is made up of a 3-D network, in which both an organic liquid solvent and other dispersed particles can be entrapped. In this work, olive oil organogels, structured from policosanol (a nutraceutical mixture of fatty alcohols), were studied in order to obtain the best formulation for producing a support for delivery of lipophilic agents (namely ferulic Acid) via oral administration. A rheological optimisation of the olive oil-policosanol organogel was first of all performed with Step Shear Rate Temperature Ramp tests. This provided important information on the policosanol fraction to be added to the system and on the onset of crystallisation temperature, an indirect measurement of the system melting point. It was found that a policosanol weight percentage of 0.03 was suitable to obtain contemporary semisolid organogels, consistent enough and thermally stable for human ingestion. In vitro tests on organogels loaded with ferulic acid were also carried out in order to simulate the oral intake of the nutraceutical compound. This evidenced a release mechanism determined by both erosion and diffusion; a good performance of gels and their ability to control the release rate through the degree of structuration were also observed.

ABSTRACT

BACKGROUND: Rituximab induces depletion of B cells and has shown efficacy in antibody-mediated autoimmune disorders. In studies on small series of patients with pemphigus, rituximab administration results in significant improvement. However, differences in inclusion criteria, treatment protocols, and follow-up make it difficult to derive uniform conclusions. OBJECTIVES: We sought to test the efficacy and tolerability of rituximab as adjuvant therapy to corticosteroids in the treatment of pemphigus. METHODS: In all, 42 patients with pemphigus were treated with rituximab and followed up for up to 5 years. No additional immunosuppressive agents were used. Steroids were rapidly tapered. Outcomes were the proportion of patients who achieved a complete response on or off therapy, the rate of discontinuation of corticosteroid within 6 months, length of remission, time to relapses, and occurrence of adverse events. RESULTS: In all, 36 of 42 patients (86%; 95% confidence interval 75%-96%) achieved a complete response on or off therapy and discontinued steroids within 6 months from induction therapy. Six patients had a complete response off therapy with an additional infusion of rituximab 6 months after initial treatment. Twenty patients experienced a total of 34 relapses; the time to relapse was 8 to 64 months. Every relapse was treated with rituximab (500 mg) without corticosteroids, which induced a new complete response. No serious adverse events were observed. LIMITATIONS: Lack of a control group is a limitation. CONCLUSIONS: Rituximab therapy induces prolonged clinical remission in patients with pemphigus. Coadministration of other immunosuppressive agents is not necessary. Relapses can be managed with additional infusions administered on demand.

ABSTRACT

Postnatal depression (PND) affects about 10-15% of women and can last more than a year in chronic cases. The Edinburgh Postnatal Depression Scale (EPDS) is a well-known questionnaire for screening PND symptomatology during the first weeks after birth, but its use in later periods is rare, reflecting a tendency to pay more attention to the onset of PND instead of its course. The study aimed to explore stability of PND symptomatology at 3, 9 and 18 months after birth, using the EPDS. Depression rate decreased from 3 to 18 months postpartum. Onset of symptoms was mainly within the first 3 months; 23.4% of 167 women showed an EPDS score > or =13 on at least one of the assessments, and 7.2% of women did so on at least two assessments. Over the 18-month period, the number of women who had recovered in the period from one assessment to the following was not significantly different from the number of women becoming depressed. Our findings underline the need to consider the existence of different courses of depressive symptomatology in research and clinical practice; women with persistent or recurrent depressive symptoms need forms of preventive intervention that cover at least the first postpartum year.
