"Circular dichroism The differential transmittance measurements were carried out in a custom-made optical setup. A white-light tungsten halogen lamp (Ocean Optics, HL-2000-HP, FL, USA) is coupled to a silver reflective collimator (RC08SMA-P01, Thorlabs) and used as an excitation light source. The light beam is passed through a Glan-Thompson Calcite Polarizer (GTH10M, Thorlabs) and directed to a super achromatic quarter wave-plate (SAQWP05M-700, Thorlabs) oriented at ±π/4 compared to the polarization direction on a rotation mount (ELL14, Thorlabs) to obtain a circularly polarized light beam. The optical elements are automatically controlled by custom software (LabView NXG). The sample is positioned at the focal plane of a pair of 4x objectives (RMS4X, NA = 0.1, Olympus). Finally, the transmitted light is fiber-coupled to a spectrometer (Ocean Optics, QEPro-FL). Steady-state circularly polarized photoluminescence Chiral photoluminescence is characterized using the same optical elements as for the dichroic transmittance but reversed in order. First, the emitted chiral photoluminescence is directed to a quarter wave-plate (10RP52-1B, Newport) oriented at ±π/4 and then to a linear polarizer (20LP-VIS-B, Newport), filtering one of the circular components. The excitation source consisted of a 200ps pulsed laser source (LDH-P-C-405 laser driven with a PDL 800B driver with 5–80 MHz repetition rate)) with its wavelength peak at 405nm. In the case of the unpolarized excitation study, the light source used for excitation was an unpolarized LED centered at 405nm (M405L4, Thorlabs) coupled to a 4x (RMS4X, NA=0.1, Olympus) objective used to collimate the diverging emitted beam and refocused with an achromatic 50mm lens upon the metasurface. Time-resolved circularly polarized photoluminescence The optical set-up used for the time-resolved photoluminescence was PicoQuant Time Correlated Single Photon Counting system (Time Harp 260 PICO board, 25 ps temporal resolution; PMA Hybrid 40 detector, 250 ps response time; 405 nm LDH-P-C-405 laser driven with a PDL 800B driver with 5–80 MHz repetition rate) equipped with a compact monochromator (Solar Laser Systems). Photoluminescence lifetimes were retrieved using the PicoQuant FluoFit Pro software, and fitting the PL decay data accounting for instrument response function.", Peer reviewed

C-S-H and C-S-Ag-H gel solutions were analysed by UV/Vis/NIR spectroscopy with a Shimadzu 3600 UV/Vis/NIR spectrometer equipped with 2H and Wlamps, a photomultiplier (UV/Vis), and a InGaAs and a PbS (NIR) detectors. The baseline reference sample was prepared with 1000 µL of MilliQ water. The samples were diluted 1:19 (50 μL of gel solution to 950 μL of of MilliQ water) and the measurements were recorded in the range of 190–850 nm, with slow scan speed. The sampling interval and the slit width were 0.5 nm and 1 nm, respectively. For the 29Si NMR analysis of dried C-S-H and C-S-Ag-H, a Bruker AV-400 (9.4 T and νR of 4 kHz) (Bruker, Germany) NMR spectrometer was used in the following conditions: pulse width of 7 μs and relaxation delay of 60 s with typically 3000 scans. The 29Si chemical shifts were determined relative to tetramethylsilane. The spectra were treated for band deconvolution into Gaussian peaks and fitted using Origin 2022 software. The micro-Raman spectra were carried out on pressed pellets of the samples with a Raman microscope Renishaw RM1000 (Renishaw, Wotton-under-Endge, UK) equipped with a Leica microscope and an electrically refrigerated CCD camera. Laser excitation line was provided by a He:Ne (633 nm wavelength, 25 mW output power with approximately 2 mW at the sample). The spectra were obtained using a 50× magnification objective, a spectral resolution of 4 cm−1, a 10 s exposure time, 5 accumulations, and 2mW laser power per spectra in the range of 2000–100 cm−1 in order to increase signal/noise ratio. The frequencies were calibrated with silicon at 520 cm−1. X-ray photoelectron (XP) and SERS spectra were taken on pressed C-S-Ag-H pellets before and after irradiation at 355 nm, and 532 nm (and of the reference C-S-H pellet). For the former technique, the analysis was performed under a base pressure lower than 7.5 · 10−9 Torr using a PHOIBOS-150 (Specs) electron analyzer, Mg Kα radiation and a constant pass energy of 100 eV and 20 eV for the wide and narrow scans, respectively. The pellets were fixed to the sample holder using double-sided conductive carbon tape to ensure a good conductivity and the X-ray gun was used at 100 W power in order to avoid any possible sample degradation induced by the X-ray irradiation. The binding energy scale was referenced to the main C 1s signal of the adventitious carbon contamination layer which was set at 284.8 eV. All the spectra were fitted using pseudo-Voigt lines (30 % Gaussian/70 % Lorentzian) and a Shirley-type background. For the SERS analysis, the same experimental conditions were used as for obtaining the Raman spectra using Rhodamine B as a probe molecule (an aliquot of 2 µl of a 5 × 10−6 M aqueous solution was dropped on the irradiated and on the non-irradiated silver-containing pellets). Additionally, different reference RhB spectra were acquired on hydroxylamine-reduced silver nanoparticles (NPs), 2 µl dropped on top of both C-S-H and C-S-Ag-H pellets for the comparison of the SERS activities. More details about samples preparation and irradiation conditions are available in Materials folder., Data life: 2024- (unlimited validity), This is the experimental dataset used in the paper Applied Surface Science, 662: 160107 (2024) (https://doi.org/10.1016/j.apsusc.2024.160107) in which a novel Surface-Enhanced Raman Spectroscopy (SERS) sensor based on a nanostructured substrate, calcium silicate hydrate (C-S-H), the main hydration product of Portland cement, was synthetized. The procedure involves first the incorporation of silver within the nanostructure of the gel (C-S-Ag-H) and second the modification of the surface of pellets of the newly synthesized material by laser irradiation at 532 nm or 355 nm. This data set includes the results of the effect of silver on the gel structure via visible UV spectroscopy, micro-Raman and 29Si Magic Angle Spinning Nuclear Magnetic Resonance (MAS NMR). It also includes the characterization analyses of the C-S-Ag-H pellets by X-ray Photoelectron Spectroscopy (XPS) to determine the silver oxidation state and the assessment of their SERS activity before and after laser irradiation using for the latter Rhodamine B (RhB) as a probe., We acknowledge financial support from the Spanish State Research Agency (AEI) through projects PID2019-104124RB-I00/AEI/10.13039/501100011033; PID2020-113900RB-I00/AEI/10.13039/ 501100011033; and PID2022-137017OB-I00/AEI/10.13039/501100011033; from European Union’s Horizon 2020 through IPERION HS (Integrated Platform for the European Research Infrastructure ON Heritage Science, GA 871034) project; and from the Community of Madrid through Maestro-Guijarro’s Youth Guarantee contract (CAM20_IQFR_AI_06)., Materials folder: “Sample_synthesis”; “Laser_irradiation_conditions” NMR folder: "NMR_readme"; "NMR_C-S-H"; "NMR_C-S-Ag-H" Raman folder: “Raman_readme"; "Raman_C-S-H"; "Raman_C-S-Ag-H"; "Raman_C-S-H_RhB"; "Raman_C-S-Ag-H_RhB" SERS folder: "SERS_readme"; "SERS_RhB_C-S-Ag-H_355"; "SERS_RhB_C-S-Ag-H_355_NPs"; "SERS_RhB_C-S-Ag-H_532"; "SERS_RhB_C-S-Ag-H_532_NPs"; "SERS_RhB_C-S-Ag-H_NPs"; "SERS_RhB_C-S-H_NPs" XPS folder: "XPS_readme"; "XPS_AgAuger_C-S-Ag-H_532"; "XPS_AgAuger_C-S-Ag-H_355"; "XPS_Ag3d_C-S-Ag-H_532"; "XPS_Ag3d_C-S-Ag-H_355"; "XPS_Ag3d_C-S-Ag-H"; "XPS_Ag3d_C-S-H"; "XPS_Ca2p_C-S-Ag-H_532"; "XPS_C1s_C-S-Ag-H_532"; "XPS_wide_C-S-Ag-H_532"; "XPS_wide_C-S-Ag-H_355"; "XPS_wide_C-S-Ag-H"; "XPS_wide_C-S-H" UV-Vis folder: "UV-VIS_readme"; "UV-VIS_C-S-H"; "UV-VIS_C-S-Ag-H", Peer reviewed

There is an urgent need to improve conventional cancer-treatments by preventing detrimental side effects, cancer recurrence and metastases. Recent studies have shown that presence of senescent cells in tissues treated with chemo- or radiotherapy can be used to predict the effectiveness of cancer treatment. However, although the accumulation of senescent cells is one of the hallmarks of cancer, surprisingly little progress has been made in development of strategies for their detection in vivo. To address a lack of detection tools, we developed a biocompatible, injectable organic nanoprobe (NanoJagg), which is selectively taken up by senescent cells and accumulates in the lysosomes. The NanoJagg probe is obtained by self-assembly of indocyanine green (ICG) dimers using a scalable manufacturing process and characterized by a unique spectral signature suitable for both photoacoustic tomography (PAT) and fluorescence imaging. In vitro, ex vivo and in vivo studies all indicate that NanoJaggs are a clinically translatable probe for detection of senescence and their PAT signal makes them suitable for longitudinal monitoring of the senescence burden in solid tumors after chemotherapy or radiotherapy., Peer reviewed

Existing databases published in open source are used to develop a tool to evaluate possible interactions between energy bills, housing rental costs and income level in households located in stressed residential market areas. As a result, the pressure of bills for the average dwelling (energy and rent price) on the average income of each census tract in the three cities analyzed is provided. The areas that exceed the mean values on the three indicators (rental price, energy bills and household income) are also detected and those that exceed the mean value for each of the three cities, increased by the standard deviation for each of the three indicators, are identified as critical areas. These results allow us to identify the stressed areas where housing expenditures exceed 30% of disposable income globally for the three cities. In addition, they provide a detailed analysis of the indicators in the stressed areas on a case-by-case approach for each of the three cities., [ES] El trabajo que se presenta supone el desarrollo por parte del Instituto de Ciencias de la Construcción Eduardo Torroja (IETcc), perteneciente a la Agencia Estatal Consejo Superior de Investigaciones Científicas (CSIC), de un modelo sobre el comportamiento energético del parque de viviendas en alquiler a través del análisis de tres ciudades situadas en diferentes zonas climáticas de España, con diferentes necesidades de calefacción y de refrigeración (Santander, Madrid y Málaga). Se utilizan bases de datos existentes publicadas en abierto para desarrollar una herramienta que permite evaluar posibles interacciones entre el coste de la energía, el coste del alquiler y el nivel de renta en los hogares situados en zonas de mercado residencial tensionado. Como resultado se ofrece la presión de las facturas para la vivienda media (energía y precio del alquiler) sobre la renta media de cada sección censal en las tres ciudades analizadas.

Excel file including: Conditions tested in the study, proximate composition and physicochemical parameters of porcine liver, degree of hydrolysis, antioxidant activity (ABTS, DPPH, FRAP and ORAC), ferrous ion chelating activity (% Chelation), and free amino acids (mg amino acid/g liver) of liver hydrolyzates., In the study of protein-rich byproducts, enzymatic hydrolysis stands as a prominent technique, generating bioactive peptides. Combining exo- and endopeptidases could enhance both biological and sensory properties. Ultrasound pretreatment is one of the most promising techniques for the optimization of enzymatic hydrolysis. This research aimed to create tasteful and biologically active pork liver hydrolyzates by using sequential hydrolysis with two types of enzymes and two types of ultrasound pretreatments. Sequential hydrolyzates exhibited a higher degree of hydrolysis than single ones. Protana Prime hydrolyzates yielded the largest amount of taste-related amino acids, enhancing sweet, bittersweet, and umami amino acids according to the Taste Activity Value (TAV). These hydrolyzates also displayed significantly higher antioxidant activity. Among sequential hydrolyzates, Flavourzyme and Protana Prime hydrolyzates pretreated with ultrasound showed the highest ferrous ion chelating activity. Overall, employing both Alcalase and Protana Prime on porcine livers pretreated with ultrasound proved to be highly effective in obtaining potentially tasteful and biologically active hydrolyzates., Grants PID2020−119684RB-I00 funded by MCINU/AEI/10.13039/501100011033 and PRE2021−100576 allocated to MILM, funded by MCIU/AEI/10.13039/501100011033 in conjunction with the European Social Fund, are acknowledged.

Excel file including: Degree of hydrolysis, antioxidant activity evaluated by DPPH, FRAP and ABTS assays, inhibition of DPP-IV of 3 enzymatic hydrolysates of Spanish dry-cured ham bone, peptide separation by reverse phase chromatography (RP-HPLC) and hydrophilic interaction liquid chromatography (HILIC); peptide identification by mass spectrometry in tandem and free amino acid content of each hydrolysate, The utilization of animal bones as a protein source could be used as a sustainable pathway for the production of bioactive compounds. In this study, bones were pretreated with pepsin enzyme (PEP) and then sequentially hydrolyzed with Alcalase (PA) and Alcalase, as well as Protana prime (PAPP). The degree of hydrolysis, antioxidant activity, and DPP-IV inhibitory activity were measured. All three hydrolysates showed antioxidant and DPP-IV inhibitory activity; however, the highest result in both bioactivities was obtained with the PAPP hydrolysate. The obtained free amino acid content was 54.62, 88.12, and 668.46 mg/100 mL of hydrolyzed in PEP, PA, and PAPP, respectively. Pepsin pretreatment did not significantly affect the degree of hydrolysis; however, it is suggested that it promoted the cleavage of certain bonds for subsequent protease action. Accordingly, a total of 550 peptides were identified in PEP hydrolysate, 1087 in PA hydrolysate, and 1124 in PAPP hydrolysate using an LC-MS/MS approach. Pepsin pretreatment could be an effective method in the utilization of bone sources for the production of antioxidant and hypoglycemic peptides., Grant PID2020-119684RB-I00 funded by MCIN/ AEI /10.13039/501100011033 is acknowledged.
