Abstract
Decellularized extracellular matrix hydrogel (dECM-G) has demonstrated its significant tissue-specificity, high biocompatibility, and versatile utilities in tissue engineering. However, the low mechanical stability and fast degradation are major drawbacks for its application in 3D printing. Herein, we report a hybrid hydrogel system consisting of dECM-Gs and photocrosslinkable gelatin methacrylate (GelMA), which resulted in significantly improved printability and structural fidelity. These pre-mixed hydrogels retained high bioactivity and tissue-specificity due to their containing dECM-Gs. More specifically, it was realized that the hydrogel containing dECM-G derived from porcine peripheral nerves (GelMA/pDNM-G) effectively facilitated neurite growth and Schwann cell migration from 2D cultured dorsal root ganglion explants. The nerve cells were also encapsulated in the GelMA/pDNM-G hydrogel for 3D culture or underwent cell-laden bioprinting with high cell viability. The preparation of such GelMA/dECM-G hydrogels enabled the recapitulation of functional tissues through extrusion-based bioprinting, which holds great potential for applications in regenerative medicine.

Soft-Dielectron Excess in Proton-Proton Collisions at sqrt[s]=13 TeV. PHYSICAL REVIEW LETTERS 2021; 127:042302.

Abstract
A measurement of dielectron production in proton-proton (pp) collisions at sqrt[s]=13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. This enables the investigation of a kinematic domain at low dielectron (ee) invariant mass m_{ee} and pair transverse momentum p_{T,ee} that was previously inaccessible at the LHC. The cross section for dielectron production is studied as a function of m_{ee}, p_{T,ee}, and event multiplicity dN_{ch}/dη. The expected dielectron rate from hadron decays, called hadronic cocktail, utilizes a parametrization of the measured η/π^{0} ratio in pp and proton-nucleus collisions, assuming that this ratio shows no strong dependence on collision energy at low transverse momentum. Comparison of the measured dielectron yield to the hadronic cocktail at 0.15<m_{ee}<0.6 GeV/c^{2} and for p_{T,ee}<0.4 GeV/c indicates an enhancement of soft dielectrons, reminiscent of the "anomalous" soft-photon and soft-dilepton excess in hadron-hadron collisions reported by several experiments under different experimental conditions. The enhancement factor over the hadronic cocktail amounts to 1.61±0.13(stat)±0.17(syst,data)±0.34(syst,cocktail) in the ALICE acceptance. Acceptance-corrected excess spectra in m_{ee} and p_{T,ee} are extracted and compared with calculations of dielectron production from hadronic bremsstrahlung and thermal radiation within a hadronic many-body approach.

Abstract
BACKGROUND Aldo-keto reductases-catalyzed transformations of ketones to chiral alcohols have become an established biocatalytic process step in the pharmaceutical industry. Previously, we have discovered an aldo-keto reductase (AKR) from Kluyveromyces marxianus that is active to the aliphatic tert-butyl 6-substituted (5R/S)-hydroxy-3-oxohexanoates, but it is inactive to aromatic ketones. In order to acquire an excellent KmAKRmutant for ensuring the simultaneous improvement of activity-thermostability toward tert-butyl 6-cyano-(5R)-hydroxy-3-oxohexanoate ((5R)-1) and broadening the universal application prospects toward more substrates covering both aliphatic and aromatic ketones, a fluorescence-based high-throughput (HT) screening technique was established. MAIN METHODS AND MAJOR RESULTS The directed evolution of KmAKR variant M5 (KmAKR-W297H/Y296W/K29H/Y28A/T63M) produced the "best" variant M5-Q213A/T23V. It exhibited enhanced activity-thermostability toward (5R)-1, improved activity toward all 18 test substrates and strict R-stereoselectivity toward 10 substrates in comparison to M5. The enhancement of enzymatic activity and the extension of substrate scope covering aromatic ketones are proposed to be largely attributed to pushing the binding pocket of M5-Q213A/T23V to the enzyme surface, decreasing the steric hindrance at the entrance and enhancing the flexibility of loops surrounding the active center. In addition, combined with 0.94 g dry cell weight (DCW) L-1 glucose dehydrogenase from Exiguobacterium sibiricum (EsGDH) for NADPH regeneration, 2.81 g DCW L-1 M5-Q213A/T23V completely converted (5R)-1 of up to 450 g L-1 at 120 g g-1 substrates/catalysts (S/C), yielding the corresponding optically pure tert-butyl 6-cyano-(3R,5R)-dihydroxyhexanoate ((3R,5R)-2, > 99.5% d.e.p ) with a space-time yield (STY) of 1.08 kg L-1 day-1 . CONCLUSIONS A fluorescence-based HT screening system was developed to tailor KmAKR's activity, thermostability and substrate scope. The "best" variant M5-Q213A/T23V holds great potential application for the synthesis of aliphatic/aromatic R-configuration alcohols.

Abstract
Extrusion-based bioprinting is an emerging and most frequently used technique for the fabrication of cell-laden constructs. A suitable hydrogel-based bioink for cell encapsulation and protection is critical for printability, structural stability, and post-printing cell viability. The thiol-ene chemistry-based gelatin-norbornene (GelNB) hydrogels have drawn much attention as a promising substitution of gelatin methacryloyl (GelMA), owing to the fast and controllable step-growth polymerization mechanism, as well as a significant reduction in reactive oxygen species (ROS) accumulation. Herein, thiolated heparin (HepSH) was synthesized and used as a macromolecular crosslinker for GelNB-based bioprinting, so that GelNB gelation became less sensitive to the thiol/ene ratio. The mechanical stability and moduli of GelNB/HepSH hydrogels were easily manipulated by the concentration and/or degree of thiol substitution. The GelNB/HepSH hydrogel allowed little intracellular ROS for encapsulated cells but provided vascular endothelial growth factor binding affinity for potential facilitation of neovascularization. Finally, the GelNB/HepSH bioink enabled a convenient printing process for both complex-structured bioscaffolds and cell-laden constructs, and resulted in good printability and high post-crosslinking cell viability. The crosslinker HepSH may serve as a multifunctional macromolecule that enables GelNB-based bioprinting in broad applications in regenerative medicine.

Abstract
Abstract
Hepatic epithelioid hemangio-endothelioma (EHE) is a rare, often misdiagnosed malignancy of vascular origin. We describe a case of a 36-year-old, who presented with a burning sensation in his chest on exercise and was believed to have bilobar intrahepatic cholangiocarcinoma. After receiving chemotherapy with partial response, the patient underwent staged resection modified ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) procedure – laparoscopic radiofrequency assisted ALPPS (RALPPS). Histological examination of the stage 1 specimen revealed EHE deposits in the left lobe of the liver. The patient proceeded to have stage 2 open right hepatectomy with concurring histology. 90-days follow-up CT scan showed almost complete resolution of EHE lesions.
Low incidence, non-specific clinical and radiological characteristics all contribute to high EHE misdiagnosis rate. Histological analysis can be used for confirmation of the diagnosis; however, specialist staining is required, which is not routinely performed. Multiple treatments are available against EHE, but only liver resection and liver transplantation are potentially curative. ALPPS and its modifications (such as RALPPS) offer an alternative for conventional two-stage hepatectomy for patients with extensive bilobar EHE, who are at risk of developing post-hepatectomy liver failure or patients with anomalous hepatic vasculature anatomy, which makes PVE challenging.

Abstract
The elliptic flow of electrons from beauty hadron decays at midrapidity (|y|<0.8) is measured in Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV with the ALICE detector at the LHC. The azimuthal distribution of the particles produced in the collisions can be parametrized with a Fourier expansion, in which the second harmonic coefficient represents the elliptic flow, v_{2}. The v_{2} coefficient of electrons from beauty hadron decays is measured for the first time in the transverse momentum (p_{T}) range 1.3-6 GeV/c in the centrality class 30%-50%. The measurement of electrons from beauty-hadron decays exploits their larger mean proper decay length cτ≈500 μm compared to that of charm hadrons and most of the other background sources. The v_{2} of electrons from beauty hadron decays at midrapidity is found to be positive with a significance of 3.75 σ. The results provide insights into the degree of thermalization of beauty quarks in the medium. A model assuming full thermalization of beauty quarks is strongly disfavored by the measurement at high p_{T}, but is in agreement with the results at low p_{T}. Transport models including substantial interactions of beauty quarks with an expanding strongly interacting medium describe the measurement within uncertainties.

Abstract
OBJECTIVE Recent studies have corroborated that circular RNAs (circRNAs) as endogenous noncoding RNAs gain research interest in carcinogenesis, functioning as prognostic and diagnostic biomarkers and therapeutic targets. The present study is aimed to determine whether circRNAs could serve as prognostic and diagnostic biomarkers to predict thyroid carcinoma. MATERIALS AND METHODS High-throughput sequencing analysis was conducted to detect circRNAs expression profile in thyroid cancer. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) measurement was utilized to validate circRNAs expression in blood and tissue specimens. Kaplan-Meier method and receiver operating characteristic (ROC) curves and the area under the ROC curve (AUC) were used to assess whether circRNAs could function as prognostic and diagnostic biomarkers of thyroid cancer, respectively. RESULTS Hsa_circ_0124055 and hsa_circ_0101622 as the most conspicuous biomarkers were significantly increased in tumor tissues and plasma of thyroid cancer patients. High hsa_circ_0124055 or hsa_circ_0101622 expression exhibited shorter overall survival. Our findings also provided strong evidence that plasma hsa_circ_0124055 (AUC = 0.836, 95% CI: 0.763-0.908, p<0.001) and hsa_circ_0101622 (AUC = 0.805, 95% CI: 0.727-0.883, p<0.001) could be used as diagnostic markers for thyroid cancer, and hsa_circ_0124055 combined with hsa_circ_0101622 could provide a more powerful diagnostic value (AUC = 0.911, 95% CI: 0.859-0.962, p<0.001) than the use of hsa_circ_0124055 or hsa_circ_0101622 alone. Furthermore, the knockdown of hsa_circ_0124055 or hsa_circ_0101622 exhibited a significant anti-proliferative and pro-apoptotic activity of thyroid cancer cells in vivo and in vitro. CONCLUSIONS Both hsa_circ_0124055 and hsa_circ_0101622 could facilitate the prognosis and diagnosis of thyroid cancer, and function as the therapeutic targets for clinical practice.

Abstract
The differential expression of genes is crucial for plant somatic embryogenesis (SE), and the accurate quantification of gene expression levels relies on choosing appropriate reference genes. To select the most suitable reference genes for SE studies, 10 commonly used reference genes were examined in synchronized somatic embryogenic and subsequent germinative cultures of Liriodendron hybrids by using quantitative real-time reverse transcription PCR. Four popular normalization algorithms: geNorm, NormFinder, Bestkeeper and Delta-Ct were used to select and validate the suitable reference genes. The results showed that elongation factor 1-gamma, histone H1 linker protein, glyceraldehyde-3-phosphate dehydrogenase and α-tubulin were suitable for SE tissues, while elongation factor 1-gamma and actin were best for the germinative organ tissues. Our work will benefit future studies of gene expression and functional analyses of SE in Liriodendron hybrids. It is also serves as a guide of reference gene selection in early embryonic gene expression analyses for other woody plant species.

Abstract
OBJECTIVE To analyze the characteristics of menicus microstructure and to reconstruct a microstructure-mimicing 3D model of the menicus. METHODS Human and sheep meniscus were collected and prepared for this study. Hematoxylin-eosin staining (HE) and Masson staining were conducted for histological analysis of the meniscus. For submicroscopic structure analysis, the meniscus was first freeze-dried and then scanned by scanning electron microscopy (SEM). The porosity of the meniscus was determined according to SEM images. A micro-MRI was used to scan each meniscus, immersed in distilled water, and a 3D digital model was reconstructed afterwards. A three-dimensional (3D) resin model was printed out based on the digital model. Before high-resolution micro-CT scanning, each meniscus was freeze-dried. Then, micro-scale two-dimensional (2D) CT projection images were obtained. The porosity of the meniscus was calculated according to micro-CT images. With micro-CT, multiple 2D projection images were collected. A 3D digital model based on 2D CT pictures was also reconstructed. The 3D digital model was exported as STL format. A 3D resin model was printed by 3D printer based on the 3D digital model. RESULTS As revealed in the HE and Masson images, a meniscus is mostly composed of collagen, with a few cells disseminated between the collagen fiber bundles at the micro-scale. The SEM image clearly shows the path of highly cross-linked collagen fibers, and massive pores exist between the fibers. According to the SEM images, the porosity of the meniscus was 34.1% (34.1% ± 0.032%) and the diameters of the collagen fibers were varied. In addition, the cross-linking pattern of the fibers was irregular. The scanning accuracy of micro-MRI was 50 μm. The micro-MRI demonstrated the outline of the meniscus, but the microstructure was obscure. The micro-CT clearly displayed microfibers in the meniscus with a voxel size of 11.4 μm. The surface layer, lamellar layer, circumferential fibers, and radial fibers could be identified. The mean porosity of the meniscus according to micro-CT images was 33.92% (33.92% ± 0.03%). Moreover, a 3D model of the microstructure based on the micro-CT images was built. The microscale fibers could be displayed in the micro-CT image and the reconstructed 3D digital model. In addition, a 3D resin model was printed out based on the 3D digital model. CONCLUSION It is extremely difficult to artificially simulate the microstructure of the meniscus because of the irregularity of the diameter and cross-linking pattern of fibers. The micro-MRI images failed to demonstrate the meniscus microstructure. Freeze-drying and micro-CT scanning are effective methods for 3D microstructure reconstruction of the meniscus, which is an important step towards mechanically functional 3D-printed meniscus grafts.

Abstract
The present study investigated the effects of protein restriction and antibiotics on the hypothalamus-pituitary-liver growth axis during the compensatory growth of growing and finishing pigs. Growth performance, serum hormones, and messenger RNA (mRNA) levels of hormones and their receptors in growth axis tissues were recorded for analyses. A total of 64 piglets (large white × Landrace × Duroc cross) with an initial weight of 10.07 ± 0.14 kg were randomly divided into 4 treatment groups of 16 piglets per group. The dietary treatments consisted of 2 protein levels (14% and 20%) and 2 antibiotic levels (no antibiotics and 20 mg/kg colistin sulfate with 50 mg/kg kitasamycin) in a 2 × 2 factorial arrangement. The study was performed over 30 d for the first stage (S1, restriction phase) and 74 d for the second stage (S2, realimentation phase). The 4 treatment diets were maintained throughout the duration in the restriction phase. The 4 groups were fed the same diet in the realimentation phase. The trial period totaled 104 d. Protein restriction decreased BW, average daily food intake, and ADG in weaning pigs (P < 0.01) and induced compensatory growth after feeding a normal diet during the growth of finishing pigs. Average daily gain increased during the last phase of compensatory growth (P < 0.01). Protein restriction increased serum GH and leptin (LEP) and the mRNA levels of liver IGF-1 receptor (IGF-1-R; P < 0.01) but decreased serum IGF-1 (P < 0.01) and the mRNA levels of liver GH receptor (GH-R; P < 0.01) and IGF-1 (P < 0.05) in weaning piglets. Serum GH was increased, but serum IGF-1 was decreased during the realimentation phase (P < 0.05). Antibiotics increased the mRNA levels of GHRH (P < 0.05) and decreased somatostatin (P < 0.01) in the hypothalamus of weaning pigs. Protein restriction and antibiotics had no interactions across the entire trial. In conclusion, the slowing of growth caused by early protein restriction may be compensated for in the later stages of pig raising, and the mechanism of compensation is related to the regulation of GH, IGF-1, GH-R, and IGF-1-R.

Abstract
The scaffolding biomaterials and their internal structures are crucial in constructing growth-permissive microenvironment for tissue regeneration. A functional bioscaffold not only requires sufficient extracellular matrix components, but also provides topological guidance by mimicry of the ultrastructure of the native tissue. In our laboratory, a decellularized nerve matrix hydrogel derived from porcine sciatic nerve (pDNM-G) is successfully prepared, which shows great promise for peripheral nerve regeneration. Herein, longitudinally oriented microchannel structures were introduced into pDNM-G bioscaffolds (A-pDNM-G) through controlled unidirectional freeze-drying. The axially aligned microchannels effectively directed and significantly promoted neurite extension and Schwann cell migration, assessed by culturing dorsal root ganglion explants on the longitudinal sections of A-pDNM-G scaffolds. Such regenerative cellular responses can be further optimized by tuning the channel sizes. In vivo studies confirmed that the implanted nerve guidance conduits containing A-pDNM-G scaffolds significantly facilitated axonal extension, myelination, and reached considerable functional recovery in 15-mm rat sciatic nerve defects. The incorporation of nerve growth factor further improved the overall performance in the grafted nerve. The bioactive pDNM-G enables controlled release of neurotrophic factor and easy integration of topological cue provided by the axially aligned microchannels into implantable bioscaffolds, which may serve in future clinical treatments of peripheral nerve injury.

Abstract
The gut hormone cholecystokinin (CCK) is primarily secreted from I-cells in the duodenum and proximal jejunum. CCK secretion is stimulated by food digests and inhibited by proteases from pancreatic juice. CCK regulates digestion and appetite, stimulates pancreatic growth, and participates in pancreatic carcinogenesis. The molecular mechanisms of CCK-induced effects are not fully understood. When the mechanisms are studied in animals, the surgical model of pancreatobiliary diversion (PBD) is frequently used. After animals have had PBD, their CCK secretion is no longer inhibited by pancreas-derived proteases, so circulating CCK is increased. PBD is established in rats and hamsters, but not in mice. In this study, we modified PBD procedures and established the model in the mouse. In an experiment, we performed PBD and sham operation (SO) in two groups of mice (20 mice per group). Twenty days after operation, 75% of the PBD mice and all SO mice survived. When plasma CCK was determined by radioimmunoassay, the PBD group had higher levels than the SO group (p < 0.001). To assess pancreatic growth, we determined pancreatic weight and pancreatic contents of protein and DNA. We also stained pancreatic sections by immunohistochemistry to show the proliferating cells that either expressed the proliferating cell nuclear antigen or were labeled with 5-bromo-2'-deoxyuridine. As a result, the pancreases of the PBD mice were heavier (p < 0.001) and had more protein (p < 0.001), DNA (p < 0.01), and proliferating cells (p < 0.01) than those of the SO counterparts. Thus, pancreatic growth was increased as a result of PBD-induced hypercholecystokininemia. The plasma and pancreatic data demonstrated that the PBD model was a success. This model may be used in CCK-related research. For instance, pancreatic cancer is frequently studied in transgenic mice. PBD may be combined with the cancer model to study the role of CCK in the molecular biology of pancreatic cancer.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2020; 79:153334. [PMID: 32920288 DOI: 10.1016/j.phymed.2020.153334] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 07/31/2020] [Accepted: 09/02/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Although garcinone C, a natural xanthone derivative identified in the pericarp of Garcinia mangostana, has been demonstrated to exert different health beneficial activities in oxidative stress and β-amyloid aggregation, the role of garcinone C in colon tumorigenesis has not been investigated. In addition, aberrant Hedgehog (Hh) signaling activation is associated with tumorigenesis including colon cancer. Here, we hypothesized that garcinone C can prevent colon tumorigenesis through regulating the Hh signaling pathway. METHOD Colony formation assay and flow cytometry were used to evaluate the effect of garcinone C on the proliferation and cell cycle progression of colon cancer cells. Protein expression of cell cycle related markers and Hh/Gli1 signaling mediators were determined. The regulatory effect of orally administered garcinone C on the Hh/Gli1 signaling pathway and colon tumorigenesis was evaluated in an azoxymethane (AOM)/dextran sulfate sodium (DSS)-induced colon cancer animal model. RESULTS Garcinone C suppressed the proliferation of colon cancer cells, induced G0/G1 cell cycle arrest, as well as regulated the expression of cell cycle-related markers such as cyclin D1, cyclin E, CDK6, and p21. Garcinone C inhibited the expression of Gli1, a key mediator of Hedgehog signaling, and protein kinase B (AKT) phosphorylation in Smo-independent colon cancer cells. In the AOM/DSS-induced colon tumorigenesis model, garcinone C significantly inhibited tumor development, regulated the expression of cell cycle markers and Gli1, and reduced AKT phosphorylation in colon tumor tissues, which is consistent with our in vitro results. CONCLUSION Garcinone C can suppress colon tumorigenesis in vitro and in vivo through Gli1-dependent non-canonical Hedgehog signaling, suggesting that it may serve as a potent chemopreventive agent against colon tumorigenesis.

Abstract
Neurological functional recovery depends on the synergistic interaction between angiogenesis and neurogenesis after peripheral nerve injury (PNI). Decellularized nerve matrix hydrogels have drawn much attention and been considered as potential therapeutic biomaterials for neurovascularization, due to their intrinsic advantages in construction of a growth-permissive microenvironment, strong affinity to multiple growth factors (GFs), and promotion of neurite outgrowth. In the present study, nerve growth factor (NGF) and vascular endothelial growth factor (VEGF) were incorporated into porcine decellularized nerve matrix hydrogel (pDNM-gel) for PNI treatment. Both GFs bound strongly to pDNM-gel and underwent a controlled release manner, which showed facilitated axonal extension and vascular-like tube formation in vitro. Especially, a companion growth was identified when human umbilical vein endothelial cells and neurons were cocultured on the GFs containing pDNM-gel. In a crushed rat sciatic nerve model, the incorporated NGF and VEGF appeared to contribute for axonal growth and neovascularization correspondingly but separately. Both GFs were equally important in improving nerve functional recovery after in situ administration. These findings indicate that pDNM-gel is not only a bioactive hydrogel-based material that can be used alone, but also serves as suitable carrier of multiple GFs for promoting an effective PNI repair. Impact statement Decellularized matrix hydrogel derived from nerve tissue has demonstrated its effectiveness in promoting nerve reinnervation, remyelination, and functionalization. Meanwhile, angiogenesis is highly desirable for treatment of long-distance peripheral nerve defects. To this end, we incorporated both vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) into porcine decellularized nerve matrix hydrogel (pDNM-gel) to induce neovascularization and neuroregeneration. At the cellular level, the pDNM-gel with both growth factors (GFs) exhibited significant capability in promoting axonal elongation, Schwann cell proliferation and migration, as well as vessel/nerve interaction. In crushed peripheral nerve injury (PNI) rat model, the integrated VEGF was more favorable for angiogenesis, whereas NGF mainly contributed to neurogenesis. However, the combination of both GFs in pDNM-gel highly facilitated motor functional recovery, highlighting the therapeutic promise of decellularized matrix hydrogel for growth factor delivery toward neuroprotection and neuroregeneration after PNI.

Abstract
To investigate the cytotoxicity of deoxynivalenol (DON) on human embryo liver CCC-HEL-1 and hepatoma cell line HepG2 cell models, both cell experience and metabolomic approach were studied. For the cell evaluation, cells viabilities of CCC-HEL-1 and HepG2 were decreased in both a time- and dose-dependent manner at concentration range from 0.08~10 μmol/l, after which the concentration of 1 μmol/l DON was selected for the next experiments. A higher production of reactive oxygen species (ROS) in DON treated CCC-HEL-1 cells was found after 2 h treatment compared with the HepG2 group, while ROS generation was significantly dropped after 48 h in both models. DON-treated CCC-HEL-1 and HepG2 cells displayed significantly decreased percentages of ΔΨm loss. For the metabolomic study based on liquid chromatography quadrupole time-of-flight mass spectrometry, it was notable that certain amino acids identified in the two DON-treated groups were upregulated. The pathway analysis also revealed that amino acid metabolism played a crucial role underlying DON exposure in the two studied models. Our results provided metabolic evidence that further confirmed the toxicological potential of DON to disturb amino acid and lipid metabolism in human embryo liver cells.

Abstract
Brachial plexus root avulsion (BPRA) is one of the most serious injuries of the upper extremity, which requires more effective treatment. Trehalose, a natural disaccharide, has reported to has a protective effect in neurodegenerative diseases. However, the effective effects and mechanism of trehalose on BPRA are still unclear. BPRA rat model were established, and then effects of trehalose on BPRA were investigated. TBHP-treated NSC34 cells with or without trehalose treatment were used for mechanism studies by Western blotting, Immunofluorescence and Flow cytometry analysis. Trehalose elevated the survival of motor neurons in rats after BPRA, suggesting a protective role of trehlose on BPRA. Trehalose treatment in rats after BPRA enhanced the autophage and thus inhibited apoptosis compared with rats in Vehicle group. Moreover, in TBHP-treated NSC34 cells, trehalose promoted the expression of autophage-related markers (LC3 and Beclin-1), concomitant with decreased levels of apoptosis. In vitro mechanism study indicated that the regulations of trehalose on autophage and apoptosis were via the AMPK-ULK1 pathway. Trehalose protects injured MNs by enhancing autophage and inhibiting apoptosis, which demonstrating the essential role of trehalose in the prevention and treatment of BPRA.

Abstract
Achieving a desirable combination of good mechanical properties and healing efficiency is a great challenge in the development of self-healing elastomers. Herein, a class of tough and strong self-healing polyacrylate elastomers (denoted as HPs) was developed simply by free-radical copolymerization of n-butyl acrylate (nBA) and tert-butyl acrylate (tBA) and a subsequent hydrolysis reaction rather than direct copolymerization of nBA and acrylic acid (AA). The tiny difference in reactivity between nBA and tBA makes the structural units of the copolymer easy to control. Precise regulation of molecular composition can be realized just by varying the relative monomer content, making its mechanical properties to vary from ductile to robust. Strikingly, when HP samples are cut off within the gauge length, they can heal into coherent and smooth samples and recover at least 79% of the original strength. Hydrogen bond interactions serve as physical cross-linking points, contributing to the high mechanical performance (fracture energy of up to 73.78 MJ·m-3 and tensile strength of up to 17.80 MPa) as well as shape memory function. Moreover, the HP samples emit strong fluorescence when exposed to a 365 nm UV lamp and exhibit an aggregation-enhanced emission effect in the state of dissolution.

Abstract
Background Lymphedema is a chronic disease results from impaired flow of the lymphatic system. Therefore, reconstruction of lymphatic system is crucial to treat limb lymphedema. Vascular endothelial growth factor (VEGFC) has been reported to be an important regulator involved in the growth and differentiation of lymphatic endothelial cells; however; the application of exosomes with VEGFC in the treatment of lymphedema has been rarely reported. Methods From the membrane-based fusion technology, we constructed engineered exosomes that overexpress CD63-VEGFC fusion protein (CD63-VEGFC/exos). We examined the in vitro effects of CD63-VEGFC/exos on the proliferation, migration, and tube formation of human dermal lymphatic endothelial cells (HDLECs) by MTT assay, migration assay, and tube formation assay, respectively. CD63-VEGFC/exos were embedded in sodium alginate hydrogel and their effect on lymphedema was evaluated by a mouse model. Results VEGFC could be successfully delivered to lymphatic endothelial cells via engineered CD63-VEGFC/exos. Treatment with CD63-VEGFC/exos resulted in a significant increase in the proliferation, migration, and tube formation of lymphatic endothelial cells. Using CD63-VEGFC/egos in sodium alginate hydrogel enabled a sequenced release of exosomes and markedly improved lymphedema in a mouse model. Conclusions Our findings supply a novel adipose tissue-derived stem cell (ADSC)-exo-based strategy that delivers target proteins to lymphatic endothelial cells and thus enhances the treatment of lymphedema.

Measurement of the Low-Energy Antideuteron Inelastic Cross Section. PHYSICAL REVIEW LETTERS 2020; 125:162001.

Abstract
In this Letter, we report the first measurement of the inelastic cross section for antideuteron-nucleus interactions at low particle momenta, covering a range of 0.3≤p<4 GeV/c. The measurement is carried out using p-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of sqrt[s_{NN}]=5.02 TeV, recorded with the ALICE detector at the CERN LHC and utilizing the detector material as an absorber for antideuterons and antiprotons. The extracted raw primary antiparticle-to-particle ratios are compared to the results from detailed ALICE simulations based on the geant4 toolkit for the propagation of (anti)particles through the detector material. The analysis of the raw primary (anti)proton spectra serves as a benchmark for this study, since their hadronic interaction cross sections are well constrained experimentally. The first measurement of the inelastic cross section for antideuteron-nucleus interactions averaged over the ALICE detector material with atomic mass numbers ⟨A⟩=17.4 and 31.8 is obtained. The measured inelastic cross section points to a possible excess with respect to the Glauber model parametrization used in geant4 in the lowest momentum interval of 0.3≤p<0.47 GeV/c up to a factor 2.1. This result is relevant for the understanding of antimatter propagation and the contributions to antinuclei production from cosmic ray interactions within the interstellar medium. In addition, the momentum range covered by this measurement is of particular importance to evaluate signal predictions for indirect dark-matter searches.

Abstract
OBJECTIVE In December 2019, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection broke out in Wuhan, China. However, we still lack a comprehensive understanding of this emerging virus. In this manuscript, we collected relevant articles and reviewed the characteristics about SARS-CoV-2. MATERIALS AND METHODS We performed an online search on PubMed and Web of Science with the keywords COVID-19, 2019-nCoV and SARS-CoV-2, and summarized the epidemiology, virology, clinical features and treatments of SARS-CoV-2 infection. RESULTS We retrieved 157 published papers about SARS-CoV-2 from January, 2020 to April, 2020. We found that SARS-CoV-2 was a kind of virus with low mortality rate and high infectivity. This virus can enter human cells through angiotensin-converting enzyme 2 (ACE2) in alveoli and activate immune response in human body. SARS-CoV-2 infection can be classified as asymptomatic, mild, common, severe, and critical. We summarized antiviral drugs against SARS-CoV-2, such as remdesivir, hydroxychloroquine and favipiravir. Because the vaccine of SARS-CoV-2 is developing, more clinical studies are needed to verify the safety and efficacy of these treatments. CONCLUSIONS SARS-CoV-2 is a novel coronavirus that has caused a global pandemic. We should pay more attention to prevent SARS-CoV-2 and try to control it sooner.
