Abstract
Grape seeds are an excellent source of flavonoids and tannins with powerful antioxidant properties. However, the astringency of tannins limits their direct incorporation into food. To overcome this challenge, we investigated the encapsulation of grape seed tannins within nanoliposomes formed by ultrasound cycling. We characterized the nanoliposomes' physicochemical properties, including encapsulation efficiency, antioxidant activity, stability, microstructure, and rheological properties. Our findings reveal that the nanoliposomes exhibited excellent stability under refrigerated conditions for up to 90 days with a mean particle size of 228 ± 26 nm, a polydispersity index of 0.598 ± 0.087, and a zeta potential of -41.6 ± 1.30 mV, maintaining a spherical multilamellar microstructure. Moreover, they displayed high antioxidant activity, with encapsulation efficiencies of 79% for epicatechin and 90% for catechin. This innovative approach demonstrates the potential of using ultrasound-assisted nanoliposome encapsulation to directly incorporate grape seed tannins into food matrices, providing a sustainable and efficient method for enhancing their bioavailability and functionality.

Abstract
Edible composite coatings (ECC) formulated from biopolymers that incorporate antioxidant molecules represent an innovative alternative to improve food texture and provide health benefits. Tannins have aroused great interest due to their ability to stabilize suspensions and counteract the effects of free radicals. The mechanical and surface properties are crucial to establishing its quality and applicability. In this study, the objective was to analyze the mechanical and surface properties of ECC made with nanoliposomes that encapsulate grape seed tannins (TLS) and polysaccharides such as hydroxypropylmethylcellulose (HPMC) and kappa carrageenan (KCG) for their future direct application in foods susceptible to oxidation. The inclusion of HPMC or KCG affected the density, showing values in the range of 1010 to 1050 [kg/m3], evidencing significant changes (p < 0.05) in the surface tension in the TLS/FS-HPMC and TLS/FS mixtures. KCG and in the dispersion coefficients, with values in the range of -2.9 to -17.6 [mN/m] in HPS (S1) and -17.6 to -40.9 [mN/m] in PDMS (S2). The TLS/FS-HPMC coating showed higher stiffness and elastic recovery capacity than the TLS/FS-KCG coating, suggesting that the presence of TLS influenced the stiffness of the polymer. HPMC is recommended as a suitable polymer for coating solids, while KCG is more appropriate for suspensions. These findings provide valuable information for directly applying these ECC compounds to food products, potentially offering better preservation and health benefits.

Abstract
The central nervous system (CNS) is particularly vulnerable to oxidative stress and inflammation, which affect neuronal function and survival. Nowadays, there is great interest in the development of antioxidant and anti-inflammatory compounds extracted from natural products, as potential strategies to reduce the oxidative/inflammatory environment within the CNS and then preserve neuronal integrity and brain function. However, an important limitation of natural antioxidant formulations (mainly polyphenols) is their reduced in vivo bioavailability. The biological compatible delivery system containing polyphenols may serve as a novel compound for these antioxidant formulations. Accordingly, in the present study, we used liposomes as carriers for grape tannins, and we tested their ability to prevent neuronal oxidative stress and inflammation. Cultured catecholaminergic neurons (CAD) were used to establish the potential of lipid-encapsulated grape tannins (TLS) to prevent neuronal oxidative stress and inflammation following an oxidative insult. TLS rescued cell survival after H2O2 treatment (59.4 ± 8.8% vs. 90.4 ± 5.6% H2O2 vs. TLS+ H2O2; p < 0.05) and reduced intracellular ROS levels by ~38% (p < 0.05), despite displaying negligible antioxidant activity in solution. Additionally, TLS treatment dramatically reduced proinflammatory cytokines’ mRNA expression after H2O2 treatment (TNF-α: 400.3 ± 1.7 vs. 7.9 ± 1.9-fold; IL-1β: 423.4 ± 1.3 vs. 12.7 ± 2.6-fold; p < 0.05; H2O2 vs. TLS+ H2O2, respectively), without affecting pro/antioxidant biomarker expression, suggesting that liposomes efficiently delivered tannins inside neurons and promoted cell survival. In conclusion, we propose that lipid-encapsulated grape tannins could be an efficient tool to promote antioxidant/inflammatory cell defense.

Abstract
e22019 Background: Conventionals serum biomarkets have a low sensibility in breast cancer diagnosis. Proteomic is a promising tool to identify new proteins profiles to be used in screening and early diagnosed. Methods: 1)Biomarker identification: Serum proteins from 114 women were separated and analysed by bidimensional gel electrophoresis; data from 72 patients (p) were compared with those from 42 control women to search for differentially expressed proteins. Several comparisons were performed between controls and p regarding clinical parameters such as histological type, tumour stage and lymph node affection (-/+). A total of 53 spots were found to be differentially expressed and identified by mass spectrometry (MS) as potential breast cancer biomarkers.2) Protein Chip development: A Protein Chip was developed with antibodies against six biomarkers and three control proteins (an antibody for the detection of a spiked control, for data normalization and two proteins as positive and negative controls). An antibody against CA15–3 antigen was also included as a reference breast tumour marker to be compared with our biomarker panel. 3) Clinical validation of the Protein Chip: A clinical validation study was carried out with 75 healthy women and 125 breast cancer p. After multivariate statistical analysis of the biomarker data, CA15–3 was discarded due to its low significance while a panel of 5 biomarkers was obtained as the best predictive model to discriminate p from healthy subjects. Results: 53 diferentially expressed proteins have been identified as potential breast cancer serum biomarkers after analysing 114 serum samples by 2DE Technology. A Protein Chip has been developed for the simultaneous detection of five serum biomarkers and three control proteins. After clinical validation with 200 p and healthy women, the sensitivity of the Protein Chip to detect breast cancer was 95% and its specificity was 27%. Conclusions: The high sensitivity of the Protein Chip suggests that it could be a valid tool to complement mammography (sensitivity < 80%) in breast cancer screening programs, specially when its sensitivity tends to decrease, as it happens in young women and dense breast cases. Larger clinical validation trials are being developed. This work is supported by INDAS BIOTECH. No significant financial relationships to disclose.
