Authors: Gómez-Merino Fernando Carlos , Castillo-González Ana María , Ramírez-Martínez Maribel , Trejo-Téllez Libia Iris
Published: November 2020

We tested two sources of lanthanum (La), LaCl3 and La(NO3)3 × 6H2O at a concentration of 40 µM each, in the treatment solution of cut flowers of 15 tulip (Tulipa gesneriana L.) cultivars. Ascorbic acid (AsA; 0.2 g/L) was used as a reference solution, while distilled water was evaluated as an absolute control. With both La sources, bud length and diameter, and stem length were increased; as a result, stem curvature was also significantly increased with La treatments. The cultivars Laura Fygi and Rosario registered the highest relative stem elongation. Lalibela and Acropolis displayed the greatest stem curvature on the last day in vase. At 3, 5, 7, 9 and 11 days after cutting, the highest solution uptake was recorded in flower stems treated with LaCl3, surpassing the control by 5, 11, 15, 18 and 24%, respectively. The relative stem elongations observed were 21.3, 27.4, 35.2 and 35.5% in the control, AsA, LaCl3 and La(NO3)3, respectively. The mean solution uptake per gram of stem fresh biomass weight was 1.44, 1.44, 1.71 and 1.54 mL in the control, AsA, LaCl3 and La(NO3)3, respectively. LaCl3 significantly increased the bud length and solution uptake of flower stems, while La(NO3)3 × 6H2O increased stem fresh weight.

The continuous search for natural products that attenuate age-related losses has increasingly gained notice; among them, those applicable for skin care have drawn significant attention. The bioester generated from theChenopodium quinoa’soil is a natural-origin ingredient described to produce replenishing skin effects. With this as motivation, we used shotgun proteomics to study the effects of quinoa bioester on human reconstructed epidermis tridimensional cell cultures after 0, 3, 6, 12, 24, and 48 h of exposure. Our experimental setup employed reversed-phase nano-chromatography coupled online with an Orbitrap-XL and PatternLab for proteomics as the data analysis tool. Extracted ion chromatograms were obtained as surrogates for relative peptide quantitation. Our findings spotlight proteins with increased abundance, as compared to the untreated cell culture counterparts at the same timepoints, that were related to preventing premature aging, homeostasis, tissue regeneration, protection against ultraviolet radiation and oxidative damage.

Fate and functional roles of Prominin 1+ cells in liver injury and cancer
Authors: Wu Raymond , Pan Stephanie , Chen Yibu , Nakano Yasuhiro , Li Meng , Balog Steven , Tsukamoto Hidekazu
Published: November 2020

Prominin 1 (PROM1) is one of a few clinically relevant progenitor markers in human alcoholic hepatitis (AH) and hepatocellular carcinoma (HCC), and mouse liver tumor initiating stem cell-like cells (TICs). However, the origin, fate and functions of PROM1+ cells in AH and HCC are unknown. Here we show by genetic lineage tracing that PROM1+ cells are derived in part from hepatocytes in AH and become tumor cells in mice with diethyl nitrosamine (DEN)-initiated, Western alcohol diet-promoted liver tumorigenesis. Our RNA sequencing analysis of mouse PROM1+ cells, reveals transcriptomic landscapes indicative of their identities as ductular reaction progenitors (DRPs) and TICs. Indeed, single-cell RNA sequencing reveals two subpopulations of Prom1+ Afp– DRPs and Prom1+ Afp+ TICs in the DEN-WAD model. Integrated bioinformatic analysis identifies Discodin Domain Receptor 1 (DDR1) as a uniquely upregulated and patient-relevant gene in PROM1+ cells in AH and HCC. Translational relevance of DDR1 is supported by its marked elevation in HCC which is inversely associated with patient survival. Further, knockdown of Ddr1 suppresses the growth of TICs and TIC-derived tumor growth in mice. These results suggest the importance of PROM1+ cells in the evolution of liver cancer and DDR1 as a potential driver of this process.

Published: November 2020

In this research, hWJ-MSCs were grown on silk scaffolds and induced towards chondrogenesis by supplementation with L-ascorbic acid (LAA) or platelet rich plasma (PRP). Silk scaffolds were fabricated with salt leaching method by mixing silk fibroin (SF) with silk spidroin (SS). The silk fibroin was obtained from Bombyx mori cocoon that had been degummed, and the silk spidroin was obtained from wild-type spider Argiope appensa. The effect of scaffold composition and inducer on cell proliferation was observed through MTT assay. The most optimal treatment then continued to be used to induce hWJ-MSC towards chondrogenic differentiation for 7 and 21 days. Scaffolds characterization showed that the scaffolds produced had 3D structure with interconnected pores, and all were biocompatible with hWJ-MSCs. Scaffold with the addition of 10% SS + 90% SF showed higher compressive strength and better pore interconnectivity in comparison to 100% silk fibroin scaffold. After 48 h, cells seeded on scaffold with spidroin and fibroin mix had flattened morphology in comparison to silk fibroin scaffold which appeared to be more rounded on the scaffold surface. Scaffold with 10% (w/w) of silk spidroin (SS) + 90% (w/w) of silk fibroin (SF) was the most optimal composition for cell proliferation. Immunocytochemistry of integrin β1 and RGD sequence, showed that scaffold with SS 10% provide better cell attachment with the presence of RGD sequence from the spidroin silk which could explain the higher cell proliferation than SF100% scaffold. Based on Alcian Blue staining and Collagen Type II immunocytochemistry (ICC), cells grown on 10% SS + 90% SF scaffold with 10% PRP supplementation were the most optimal to support chondrogenesis of hWJ-MSCs. These results showed that the addition of spidroin silk from A. appensa. had impact on scaffold compressive strength and chondrogenic differentiation of hWJ-MSC and had the potential for further development of bio-based material scaffold in cartilage tissue engineering.

Does it take two to tango? RING domain self-association and activity in TRIM E3 ubiquitin ligases
Authors: Fiorentini Filippo , Esposito Diego , Rittinger Katrin
Published: November 2020

TRIM proteins form a protein family that is characterized by a conserved tripartite motif domain comprising a RING domain, one or two B-box domains and a coiled-coil region. Members of this large protein family are important regulators of numerous cellular functions including innate immune responses, transcriptional regulation and apoptosis. Key to their cellular role is their E3 ligase activity which is conferred by the RING domain. Self-association is an important characteristic of TRIM protein activity and is mediated by homodimerization via the coiled-coil region, and in some cases higher order association via additional domains of the tripartite motif. In many of the TRIM family proteins studied thus far, RING dimerization is an important prerequisite for E3 ligase enzymatic activity though the propensity of RING domains to dimerize differs significantly between different TRIMs and can be influenced by other regions of the protein.

Context.The study of exoplanet atmospheres is essential for understanding the formation, evolution, and composition of exoplanets. The transmission spectroscopy technique is playing a significant role in this domain. In particular, the combination of state-of-the-art spectrographs at low- and high-spectral resolution is key to our understanding of atmospheric structure and composition.

Aims.We observed two transits of the close-in sub-Saturn-mass planet, WASP-127b, with ESPRESSO in the frame of the Guaranteed Time Observations Consortium. We aim to use these transit observations to study the system architecture and the exoplanet atmosphere simultaneously.

Methods.We used the Reloaded Rossiter-McLaughlin technique to measure the projected obliquityλand the projected rotational velocityveq⋅sin(i*). We extracted the high-resolution transmission spectrum of the planet to study atomic lines. We also proposed a new cross-correlation framework to search for molecular species and we applied it to water vapor.

Results.The planet is orbiting its slowly rotating host star (veq⋅sin(i*) = 0.53−0.05+0.07km s−1) on a retrograde misaligned orbit (λ= −128.41−5.46+5.60°). We detected the sodium line core at the 9-σconfidence level with an excess absorption of 0.34 ± 0.04%, a blueshift of 2.74 ± 0.79 km s−1, and a full width at half maximum of 15.18 ± 1.75 km s−1. However, we did not detect the presence of other atomic species but set upper limits of only a few scale heights. Finally, we put a 3-σupper limit on the average depth of the 1600 strongest water lines at equilibrium temperature in the visible band of 38 ppm. This constrains the cloud-deck pressure between 0.3 and 0.5 mbar by combining our data with low-resolution data in the near-infrared and models computed for this planet.

Conclusions.WASP-127b, with an age of about 10 Gyr, is an unexpected exoplanet by its orbital architecture but also by the small extension of its sodium atmosphere (~7 scale heights). ESPRESSO allows us to take a step forward in the detection of weak signals, thus bringing strong constraints on the presence of clouds in exoplanet atmospheres. The framework proposed in this work can be applied to search for molecular species and study cloud-decks in other exoplanets.

Context. The detection and characterization of exoplanet atmospheres is currently one of the main drivers pushing the development of new observing facilities. In this context, high-resolution spectrographs are proving their potential and showing that high-resolution spectroscopy will be paramount in this field.

Aims. We aim to make use of ESPRESSO high-resolution spectra, which cover two transits of HD 209458b, to probe the broadband transmission optical spectrum of the planet.

Methods. We applied the chromatic Rossiter–McLaughin method to derive the transmission spectrum of HD 209458b. We compared the results with previous HST observations and with synthetic spectra.

Results. We recover a transmission spectrum of HD 209458b similar to the one obtained with HST data. The models suggest that the observed signal can be explained by only Na, only TiO, or both Na and TiO, even though none is fully capable of explaining our observed transmission spectrum. Extra absorbers may be needed to explain the full dataset, though modeling approximations and observational errors can also be responsible for the observed mismatch.

Conclusions. Using the chromatic Rossiter–McLaughlin technique, ESPRESSO is able to provide broadband transmission spectra of exoplanets from the ground, in conjunction with space-based facilities, opening good perspectives for similar studies of other planets.

Published: November 2020

All construction activities will inevitably produce CO2 emissions from the production process of materials, transportation, the usage of plant and equipment, the construction process, up to building demolition. Therefore, it is very important to understand the construction process and the amount of CO2 emissions released at each stage of the construction process. This research aims to estimate the amount of CO2 emissions during the construction process of a rigid pavement project. Data collection is done by observing rigid pavement of Palur Flyover project as a case study. The results show the total CO2 emissions during the construction process equals 92.901 tonnes CO2e, consisting of 91.334 tonnes CO2e (98.3%) of off-site activities, and 1.567 tonnes CO2e (1.7%) of on-site activities. The highest emission from off-site activities coming from material production of cement and steel rebars of 88.166 tonnes CO2e (94.9%), and the material transportation process of 3.168 tonnes CO2e (3.4%). This research shows that off-site construction activities, i.e. material production and transportation significantly influence the extent of CO2 emissions in this rigid pavement project. Therefore, it is recommended that strategic efforts for reducing the CO2 emissions of other typical rigid pavement projects should focus on these two.

Sanitary landfill is the most commonly used way to process municipal solid waste (MSW) in most countries including Indonesia. Sanitary landfill system produces leachate which contains a lot of inorganic pollutants, heavy metals, dissolved organic matter, and xenobiotics. Most leachate treatment plants in Indonesia consist of stabilization ponds, aeration ponds, anaerobic ponds, maturation ponds, and tertiary treatment such as wetlands. A small part of waste water treatment plant (WWTP) consists of equalization tanks, facultative bodies, aeration tanks, polishing pools, sedimentation tanks, chemical and biological processing tanks, mud ponds and sand filters. In fact, leachate was found at depths of 4, 9, 15, 20, 30 m in final processing site in the Gampong Jawa, Banda Aceh. Real conditions, some WWTPs do not function properly, buildings are damaged, and effluent quality exceeds the standard. Leachate needs to be managed properly, so as not to cause pollution to ground water and surface water. Although, there are many negative problems related to leachate management, but there are many opportunities that can be developed. These opportunities not only reduce their negative impacts but also help meet energy needs and improve environmental health in the long run. This review article aims to discuss the opportunities and challenges of leachate recirculation in Indonesia in terms of technical aspects.

Fouling is an adverse problem for ship. Fouling itself is some kind of marine biota like shells, mussels, or barnacles, which grow and live on the surface of ship’s hull or inside the ship’s piping system. Many methods have been applied to prevent fouling. Impressed Current Anti Fouling (ICAF) was developed and applied as an alternative in mitigation of fouling. The aim of the research was to determine the effects of electrical current, duration time, salinity on Anadara granosa death in simple ICAF system. The simple ICAF reactor was operated in electric current of 1.5 A, and duration time (1,3,5,7 dan 9 h), variations of salinity (33 ‰, 35‰ and 37‰) and the size of shell (1-2 cm and 2-3 cm). Steel of AH36 has a role as a cathode, meanwhile pure copper (Cu) was an anode. The death of Anadara granosa was conducted using direct observation. The direct observation was carried out by opening the shells one by one. The death of mollusc can be confirmed by looking the response from the mollusc. If the mollusc showed no response when it was pierced, it indicated that the mollusc was dead. Besides that, there was white slime inside the mollusc. Based on the results, the death of Anadara granosa with shell size of 2-3 cm showed the highest percentage of 90% at electrical current of 1.5 A, duration time of 9 h, and salinity of 37 ‰. Meanwhile the smallest percentage of Anadara granosa death reached 10% at electrical current of 1.5 A, duration time of 7 h, and salinity of 33 ‰ for shell size of 1-2 cm. In conclusion, duration time and salinity were higher so that the death of Anadara granosa was higher too. Besides that, the small size of Anadara granosa was more resistant.
