Abstract

Abstract Objective Neuromyelitis optica spectrum disorders (NMOSD) are rare inflammatory astrocytic diseases of the central nervous system (CNS). The roles of immune response gene‐1 (IRG1) and the IRG1–itaconic acid–NLRP3 inflammatory pathway in the pathogenesis of NMOSD and the effects of 4‐octyl itaconate (4‐OI) on the NLRP3 inflammatory pathway in NMOSD are unclear. This study aimed to determine the role of IRG1 and the activation status of the NLRP3 inflammatory pathway in acute‐onset NMOSD and to investigate the inhibitory effects of 4‐OI on NLRP3 inflammasome activation via the IRG1–itaconic acid–NLRP3 pathway in monocytes and macrophages by using in vitro models. Methods Peripheral blood mononuclear cells (PBMCs) and serum were collected from patients with acute NMOSDs and healthy controls (HC), followed by monocyte typing and detection of the expression of NLRP3‐related inflammatory factors. Subsequently, the effects of 4‐OI on the IRG1–itaconic acid–NLRP3 pathway were investigated in peripheral monocytes from patients with NMOSD and in macrophages induced by human myeloid leukemia mononuclear cells (THP‐1 cells) via in vitro experiments. Results Patients with acute NMOSD exhibited upregulated IRG1 expression. In particular, the upregulation of the expression of the NLRP3 inflammasome and proinflammatory factors was notable in monocytes in acute NMOSD patients. 4‐OI inhibited the activation of the IRG1–itaconic acid–NLRP3 inflammatory pathway in the PBMCs of patients with NMOSD. Interpretation 4‐OI could effectively inhibit NLRP3 signaling, leading to the inhibition of proinflammatory cytokine production in patients with NMOSD‐derived PBMCs and in a human macrophage model. Thus, 4‐OI and itaconate could have important therapeutic value for the treatment of NMOSD in the future.

Abstract

International audience; Near-infrared Spectrometer (NIRS3) onboard Hayabusa2 successfully obtained reflectance spectra of the C-type near-Earth asteroid Ryugu over a wavelength range of 1.8-3.2 µm. It was observed that Ryugu exhibits very low albedo (less than 0.02 at 2.0 μm), a slightly positive spectral slope, and an ubiquitous weak OH absorption band at 2.72 μm. These properties are nearly homogeneous across the asteroid surface. However, data of regions near the equator with ~40 m spatial resolution (~20 km altitude) exhibit variations in the 2.0-μm albedo that are possibly associated with geomorphological features. Reflectance values are higher near crater rims and lower in crater centers. Future updates to the photometric correction may change these apparent associations, but it is also observed that spectra of several flat areas without any obvious geomorphological features show relatively high reflectance (e.g., near 270, 300, and 350 degrees longitude, close to the equatorial ridge). If verified, the brighter areas could indicate surface materials that (a) are relatively carbon-poor, (b) have different physical properties, such as smaller grain size and/or decreased porosity, and/or (c) exhibit different forms/degrees of space weathering. Comparing spectra of carbonaceous chondrites with those of Ryugu shows that no meteorites are an ideal spectral match to Ryugu at all wavelengths. However, spectra of shocked or heated carbonaceous chondrites are most similar with their low albedo and weak, narrow OH absorption feature at 2.72 μm. Future lab analyses of samples returned from Ryugu will provide additional information on the mineralogical and chemical properties of Ryugu and how these relate to its spectral characteristics.

Abstract

International audience; On 27 June 2018, JAXA's Hayabusa2 spacecraft arrived at a distance of 20 km from its target 162173 Ryugu, a sub-km sized asteroid in the near-Earth space, and began its 1.5-year asteroid proximity operation. We have performed near-infrared (1.8-3.2 µm) spectroscopic observations of Ryugu using the NIRS3 instrument onboard Hayabusa2 to begin characterizing and mapping the surface composition. The initial data, obtained by NIRS3 at a spatial resolution of about 35 m, show a very dark surface with little spectral variations across the surface. At this stage, the lack of a significant 2.7-µm feature illustrates that the spectra of Ryugu are different from those of phyllosilicate-rich carbonaceous chondrites. We will present the results of the analysis of the NIRS3 data, including the high-resolution data to be obtained during the first descent operations.

Abstract

Phyllosilicates, carbonates, zeolites, and sulfates on Mars give clues about the planet's past environmental conditions, but little is known about the specific conditions in which these minerals formed within the crust and at the surface. The aim of the present study was to gain increased understanding on the formation of secondary phases by hydrothermal alteration of basaltic glass. The reaction processes were studied under varying conditions (temperature, pCO2, water:rock ratio, and fluid composition) with relevance to aqueous hydrothermal alteration in fully and partly saturated Martian basalt deposits. Analyses made on reaction products using X‐ray diffraction (XRD) and scanning electron microscope (SEM) were compared with near infrared spectroscopy (NIR) to establish relative detectability and spectral signatures. This study demonstrates that comparable alteration minerals (phyllosilicates, carbonates, zeolites) form from vapor condensing on mineral surfaces in unsaturated sediments and not only in fully water‐saturated sediments. In certain environments where water vapor might be present, it can alter the basaltic bedrock to a suite of authigenic phases similar to those observed on the Martian surface. For the detection of the secondary phases, XRD and SEM‐EDS were found to be superior to NIR for detecting and characterizing zeolites. The discrepancy in detectability of zeolites between NIR and XRD/SEM‐EDS might indicate that zeolites on Mars are more abundant than previously thought. [ABSTRACT FROM AUTHOR]

Abstract

Severe weather conditions such as rain and snow often reduce the visual perception quality of the video image system, the traditional methods of deraining and desnowing usually rarely consider adaptive parameters. In order to enhance the effect of video deraining and desnowing, this paper proposes a video deraining and desnowing algorithm based on adaptive tolerance and dual-tree complex wavelet. This algorithm can be widely used in security surveillance, military defense, biological monitoring, remote sensing and other fields. First, this paper introduces the main work of the adaptive tolerance method for the video of dynamic scenes. Second, the algorithm of dual-tree complex wavelet fusion is analyzed and introduced. Using principal component analysis fusion rules to process low-frequency sub-bands, the fusion rule of local energy matching is used to process the high-frequency sub-bands. Finally, this paper used various rain and snow videos to verify the validity and superiority of image reconstruction. Experimental results show that the algorithm has achieved good results in improving the image clarity and restoring the image details obscured by raindrops and snows.

Abstract

Exogenous nucleotides (NTs) are considered conditionally essential nutrients, and the brain cannot synthesize NTs de novo. Therefore, the external supplementation of exogenous NTs is of great significance for maintaining normal neuronal metabolism and function under certain conditions, such as brain aging. This study, therefore, sets out to assess the neuroprotective effect of four kinds of single exogenous NTs and a mixture of the NTs, and to elucidate the potential mechanism. A rat pheochromocytoma cell line PC-12 was treated with different concentrations of exogenous NTs after 4 h of exposure to 200 µM H2O2. We found that the exogenous NTs exerted significant neuroprotection through decreasing neuron apoptosis and DNA damage, ameliorating inflammation and mitochondrial dysfunction, promoting cell viability, and augmenting antioxidant activity, and that they tended to up-regulate the NAD+/SIRTI/PGC-1α pathway involved in mitochondrial biogenesis. Among the different NTs, the neuroprotective effect of AMP seemed to be more prominent, followed by the NT mixture, NMN, and CMP. AMP also exhibited the strongest antioxidant activity in H2O2-treated PC-12 cells. UMP was excellent at inhibiting neuronal inflammation and improving mitochondrial function, while GMP offered major advantages in stabilizing mitochondrial membrane potential. The mixture of NTs had a slightly better performance than NMN, especially in up-modulating the NAD+/SIRTI/PGC-1α pathway, which regulates mitochondrial biogenesis. These results suggest that antioxidant activity, anti-inflammatory activity, and protection of mitochondrial function are possible mechanisms of the neuroprotective actions of exogenous NTs, and that the optimization of the mixture ratio and the concentration of NTs may achieve a better outcome.

Abstract

Introduction: The Ryugu samples brought back by the Hayabusa2 spacecraft in December 2020 have been delivered to the JAXA Extraterrestrial Curation Center [1]. Bulk samples and then individual grains have been picked up and stored into sapphire dishes, weighted, and analyzed with an optical microscope, FTIR spectroscopy, and MicrOmega hyperspectral imaging [2-4] for initial description. The MicrOmega instrument used in the JAXA Extraterrestrial Curation Center is a near-infrared (NIR) hyperspectral microscope [5]. It has a total field of view of ~5 mm x 5 mm, with a resolution of ~22 µm/pixel in the focal plane. It covers the spectral domain from 0.99 µm to ~3.6 µm, enabling the identification of most candidate minerals and molecules of relevance (e.g. mafic minerals, altered phases, salts, ices, aliphatic/aromatic CH, NH-rich compounds) [6]. In particular, in the spectral domain of MicrOmega, carbonates have a strong characteristic double absorption band in the 3.3-3.5 µm range, accompanied by two other weaker bands around 2.5 and 2.3 µm. The exact position of these bands varies with the cation content of the carbonate [7]. Iron-bearing carbonates also show a strong Fe2+ absorption below 1.5 µm. Initial analyses with MicrOmega were first made on the bulk samples from chambers A and C of the Hayabusa 2 returned capsule, and then on individual grains stored in their sapphire dishes (by the end of 2021, ~180 individual grains have been analyzed), as well as 14 sub-bulks. Such extensive characterization provides a unique opportunity to assess the different processes that shaped Ryugu's material. Here, we focus on the MicrOmega analyses of Ryugu carbonate-rich grains and inclusions which record the alteration processes encountered on Ryugu parent body. Results: Spectra of the Ryugu samples at the mm-scale share common features: a very low reflectance (2-3%), an absorption band centered around 2.715 µm attributed to OH, and a weak absorption centered around 3.4 µm attributed to a variety of CH-rich compounds and carbonates [2]. Only at a sub-millimeter scale do heterogeneities clearly show up, either or both at grain level or as inclusions within grains. In total, more than 200 carbonate-rich areas larger than ~45 µm (2x2 MicrOmega pixels) have been detected among the grains and bulks/sub-bulks observed with MicrOmega by the end of 2021 (which does not preclude the presence of carbonates at finer scale). While most of the detections are smaller than ~100 µm in size, the largest carbonate-rich areas can reach several hundreds of µm, displaying various kinds of morphologies. The analysis of the position of the absorption features enabled the identification of various types of carbonates, similar to dolomite and breunnerite for the large majority of them. These various detections and the context in which they are made will be presented. Implications for the alteration processes encountered on Ryugu's parent body will also be discussed.

Abstract

Introduction: On December 6, 2020, the Hayabusa2 mission successfully returned to Earth ~ 5.4 g of samples collected at the surface of the C-type asteroid Ryugu [1,2]. Its surface was first sampled on February 22, 2019 ("bulk A"), then on July 11, 2019, close to a 15-meter large artificial crater, so as to possibly access sub-surface material ("bulk C") [3]. The collected samples are now kept at ISAS (Institute of Space and Astronautical Science) for a first round of preliminary analyses, with the objective of characterizing in a non-destructive manner both the bulk samples and a few hundreds of grains extracted from them [4]. In particular, the goal is 1) to support their further detailed characterization by the international Initial Analysis Teams, and 2) to build a catalogue of the grains, accessible to the international community through AO selection, starting mid-2022. Importantly, the analyzed samples have always been kept, since their collection, in a fully clean and controlled environment either under vacuum or ultra-clean GN2. Methods: The preliminary characterization of these samples is being conducted with a visible microscope with six color filters [4], a FTIR spectrometer (1-4 μm) [4], and MicrOmega, a hyperspectral microscope [5], operating in the near-infrared range (0.99-3.65 μm) where diagnostic signatures of most candidate minerals and molecules of relevance (e.g. mafic minerals, altered phases, salts, ices, aliphatic/aromatic CH, NH-rich compounds) can be found. For each 22.5x22.5 μm² pixel of the 250x256 pixels² field of view, the reflectance spectrum is retrieved in up to 400 contiguous spectral channels. Both the negligible amount of illuminating power at less than 10-8 W/px and the lack of contact with the samples allow entirely non-destructive and non-invasive characterization. By the beginning of 2022, bulk samples from chamber A and chamber C of the Hayabusa2 returned capsule (each divided into 3 sub-bulks), as well as >200 individual grains and 14 "small-bulks" extracted from them have been analyzed with MicrOmega. Results: When analyzed at the mm-scale by averaging thousands of pixels, the spectra of bulk A and bulk C exhibit a pattern similar to those acquired remotely down to the meter scale by the NIRS3 IR spectrometer on board Hayabusa2 [6]. The global reflectance is extremely low, 2-3 %, in agreement with the measurements of the ONCs and NIRS3 at Ryugu [7,8], and consistent with the taxonomic spectral classification of Ryugu as a C-type asteroid [1,2]. The main spectral feature is the diagnostic OH absorption centered at 2.715 +/-0.005 μm, position compatible with that of NIRS3 spectra [8,9]. No significant differences can be observed between bulk A and bulk C for this specific feature. MicrOmega spectra also exhibit a broad feature in the 3.3-3.5 μm range, centered around 3.4 μm, present throughout the sub-bulk samples. This feature is considered indicative of the large-scale presence of a variety of CHrich compounds and carbonates. A fainter ~3.1 μm broad feature, indicative of the presence of NH-bearing compounds is also detected, although with varying and much fainter intensities. Only at a sub-millimeter scale do heterogeneities clearly show up, either or both at grain level or as inclusions within grains. Detections include for example: 1) carbonates of various compositions, detected on a rather large number of occurrences with sizes ranging from a few tens to a few hundreds of micrometers [10]; 2) spots enriched in organics, in particular through a 3.4 μm feature indicative of the presence of aliphatic compounds; 3) spots enriched in a nitrogen-rich phase, through a ~3.1 μm feature sometimes coupled to additional spectral features. These detections, as well as others, will be presented and candidates will be discussed. Noticeably, no chondrules nor refractory inclusions have been identified yet. Conclusion: The initial spectral characterization of the returned samples by MicrOmega currently points towards Ryugu containing a fascinating variety of grains, including OH-, CH- and NH- rich compounds spread at a global scale, and alteration products, among which highly diagnostic carbonates. The occurrence of volatile-rich species, likely originating from the outer solar system, would support Ryugu having preserved some of its building blocks, together with their partially altered phases. The Hayabusa2 returned samples, thus, appear among the most primordial material available in our laboratories. [ABSTRACT FROM AUTHOR]

Abstract

The total cross section and the forward-backward asymmetry for the process e(+)e --> mu(+)mu(-)(n gamma) are measured in the energy range 20-136 GeV by reconstructing the effective centre-of-mass energy after initial state radiation. The analysis is based on the data recorded with the ALEPH detector at LEP between 1990 and 1995, corresponding to a total integrated luminosity of 143.5 pb(-1). Two different approaches are used: in the first one an exclusive selection of events with hard initial state radiation in the energy range 20-88 GeV is directly compared with the Standard Model predictions showing good agreement. In the second one, all events are used to obtain a precise measurement of the energy dependence of sigma(0) and A(FB)(0) from a model independent fit, enabling constraints to be placed on models with extra Z bosons.

Abstract

MicrOmega, a miniaturized near-infrared hyperspectral microscope, has been selected to characterize in the laboratory the samples returned from Ryugu by the Hayabusa2 mission. MicrOmega has been delivered to the Extraterrestrial Samples Curation Center of the Japanese Aerospace eXploration Agency at the Institute of Space and Astronautical Science in July 2020 and then mounted and calibrated to be ready for the analyses of the samples returned to Earth on December 6, 2020. MicrOmega was designed to analyze the returned samples within a field of view of 5 × 5 mm 2 and a spatial sampling of 22.5 µm. It acquires 3D near-infrared hyperspectral image-cubes by imaging the sample with monochromatic images sequentially covering the 0.99-3.65 µm spectral range, with a typical spectral sampling of 20 cm -1 . This paper reports the calibration processes performed to extract scientific data from these MicrOmega image-cubes. The determination of the instrumental response and the spectral calibration is detailed. We meet or exceed the goals of achieving an accuracy of ∼20% for the absolute reflectance level, 1% for the relative wavelength-to-wavelength reflectance, and <5 nm for the peak position of the detected absorption features. For the nominal measurements of Ryugu samples with MicrOmega/Curation, the instrument performance also reaches a signal-to-noise ratio of >100 over the entire spectral range. By characterizing the entire collection of the returned samples at the microscopic scale, MicrOmega/Curation offers the potential to provide unprecedented insights into the composition and history of their asteroid parent body.

Abstract

Ryugu is a carbonaceous rubble-pile asteroid visited by the Hayabusa2 spacecraft. Small rubble pile asteroids record the thermal evolution of their much larger parent bodies. However, recent space weathering and/or solar heating create ambiguities between the uppermost layer observable by remote-sensing and the pristine material from the parent body. Hayabusa2 remote-sensing observations find that on the asteroid (162173) Ryugu both north and south pole regions preserve the material least processed by space weathering, which is spectrally blue carbonaceous chondritic material with a 0-3% deep 0.7-µm band absorption, indicative of Fe-bearing phyllosilicates. Here we report that spectrally blue Ryugu's parent body experienced intensive aqueous alteration and subsequent thermal metamorphism at 570-670 K (300-400 °C), suggesting that Ryugu's parent body was heated by radioactive decay of short-lived radionuclides possibly because of its early formation 2-2.5 Ma. The samples being brought to Earth by Hayabusa2 will give us our first insights into this epoch in solar system history., (© 2021. The Author(s).)

Abstract

Aggressive surgical cytoreduction has been shown to have a positive impact on survival of patients with ovarian cancer. After first-line chemotherapy, 47% of patients relapse within 5 years, and median survival after second line chemotherapy is 10-15 months. Adding intraperitoneal chemohyperthermia (IPCH) to surgical cytoreduction could further control ceolomic spread of disease. The aim of this study was to determine morbidity and mortality, regional relapse-free survival and, preliminarily, overall survival after combining cytoreductive surgery with IPCH for the treatment of peritoneal carcinomatosis from ovarian epithelial cancer relapsed after prior chemotherapy. Thirty women affected with such a relapse were included. Patients underwent extensive cytoreductive surgery including tumor resections and peritonectomy, followed by intraoperative IPCH with cisplatin. Complete surgical cytoreduction down to nodules less than 2.5 mm (CC0-CC1) was obtained in 23 patients (77%). One patient died postoperatively from a pulmonary embolism. Major postoperative morbidity was 5/30 (16.7%). We registered one case of anastomotic leakage, a spontaneous ileum perforation, a postoperative cholecystitis, a hydrothorax, and one patient with bone marrow toxicity. Kaplan-Meier estimates of median locoregional relapse-free survival and median overall survival were 17.1 months and 28.1 months, respectively. Patients with CC0-CC1 had locoregional relapse-free and overall survival rates of 24.4 and 37.8 months, whereas the remainder had survival rates of 4.1 and 11.0 months. We concluded that cytoreductive surgery combined with IPCH is feasible with acceptable morbidity and mortality and seems to promise good results in selected patients affected with peritoneal carcinomatosis from ovarian cancer.
